Background The aim of this study was to examine how patterns of academic and behavior problems in the 1047297rst
grade relate to longitudinal transitions in marijuana use from middle school through entry into high school
among African-AmericansMethods Latent class and latent transition analyses were conductedon a communitysampleof 458 low-income
urban-dwelling African-Americans
Results Two behavior problem classes emerged at school entry externalizing and attentionconcentration
Academic problems co-occurred with both problem behavior classes although more strongly with attention
concentration Youth in the attention concentration problem class were more likely to transition from no
marijuana involvement to use and problems beginning in the 7th grade and to use and problems given the op-
portunity to use marijuana early in high school compared to youth with no problems Youth in the externalizing
behavior problem class were signi1047297cantly more likely to transition from no involvement to having a marijuana
opportunity during the transition to high school compared to youth in the attentionconcentration problems
class
Conclusions These 1047297ndings highlight the importance of developing prevention programs and providing school
services that address the co-occurrence of academic and behavior problems as well as their subtype speci1047297c
risks for marijuana involvement particularly for low-income minority youth who may be entering school less
ready than their non-minority peers These 1047297ndings also provide evidence for a need to continue to deliver
interventions in middle school and high school focused on factors that may protect youth during these critical
transition periods when they may be especially vulnerable to opportunities to use marijuana based on theiracademic and behavioral risk pro1047297les

Total Math and Total Reading normal curve equivalent scores for each
child in the 1047297rst grade to create a composite academic achievement
variable The average was then dichotomized to indicate those children
with the most achievement dif 1047297culties (ie bottom 25 on achieve-
ment) In addition to this standardized achievement measure we
included the teacher report of the childs overall progress in the fall of
the 1047297rst grade This item was rated on a 6-point scale (1 = excellent
to 6 = extremely poor) and dichotomized for analyses to indicate
those with poor to extremely poor progress versus those with good toexcellent progress
223 Marijuana involvement in 6th 7th 8th and 9th grades
We considered responses to1047297ve questions about marijuana involve-
ment gathered in the spring of the 6th 7th 8th and 9th grades Oppor-
tunity to usemarijuanainvolved askingwhether a youth hadldquoever been
offeredrdquo marijuana as described by Crum Lillie-Blanton and Anthony
(1996) Adolescent reports of marijuana use were based on asking
ldquoHave you ever used marijuanardquo Frequency of marijuana use was
measured based on questions from the Monitoring the Future survey
( Johnston OMalley amp Bachman 1995) and was de1047297ned as ever using
marijuana more than a couple of times ie on three or more occasions
This low threshold for frequent marijuana use was chosen to be
meaningful for this sample of young adolescents It also gave us the
opportunity to explore whether this level of use is problematic in
young adolescents For this reason we also looked at health and social
problems associated with marijuana use Health and social problems
were assessed by asking if they ever experienced any health problems
or social problems from using marijuana The speci1047297c problems
comprising these two questions are listed in Appendix A
224 Demographic information
The school district provided information on the students sex and
ethnicity School records indicating each students free or reduced-cost
meal status were collapsed into a dichotomous variable of free or
reduced lunch versus self-paid lunch as an indicator of students
socioeconomic status
23 Statistical analyses
A cross-sectional latent class analysis (LCA) was applied to examine
the structure underlying the 1047297ve indicators of academic and behavior
problems in the 1047297rst grade The basic premise of LCA is that within
classes behaviors are locally independent (Lazarsfeld 1950) The goal
is to identify the smallest number of classes that adequately describes
the association among the behaviors Information about the resultant
class structure is conveyed through two sets of parameters the
probability of having high levels of academic andor behavior problems
within a particular class (item probabilities) and the proportion of
youth in each class (class prevalences)
A longitudinal latent class model (or latent stage model) was then
applied to examine the structure underlying the 1047297ve items comprising
the marijuana involvement pro1047297le over time While in principle it ispossible to allow the item probabilities and hence latent structure to
vary over time forthe 6thto 9th grade marijuana indicators this implies
that the de1047297nition of marijuana involvement is changing which would
substantially complicate the interpretation of a longitudinal model
Therefore we constrained the item probabilities to be constant over
time ie the probability of reporting a behavior within a latent stage
was thesame in each grade This is analogous to constraining the factor
loadings to be equal over time in a longitudinal factor analysis model
(sometimes referred to as factor invariance) The latent stage preva-
lences however were allowed to vary over time ie the proportion of
youth in each stage could change over time
Our model building strategy for the two sets of latent class models
involved starting with the most parsimonious one-class (or one-stage)
model and 1047297tting successive models with an increasing number of
latent classes (or stages) in order to determine the most parsimonious
model that provided an adequate 1047297t to the data The goodness-of-1047297t of
various models was evaluated using the Akaikes Information Criteria
(AIC) a global 1047297t index that combines goodness-of-1047297t and parsimony
Because we were concerned that the statistical power in this study
may be limited by the sample size we chose to rely on the AIC over
other global 1047297t indices as it is known to favor more complex models
(Lin amp Dayton 1997) Entropy was calculated to provide an indication
of the overall degree of classi1047297
cation uncertainty in the solution(Celeuxamp Soromenho 1996) Lower valuesof AIC are preferable where-
as higher values (or values closer to 1) are better for entropy For latent
class models there are considerations other than global goodness-of-1047297t
indices In particular an examination of thevalidityof thelocal indepen-
dence assumption which is the hallmark of LCA is critical We used a
modi1047297ed version of Garrett and Zegers (2000) Log-Odds Ratio Check
This method involves calculating thelog-oddsratio in both theobserved
and expected two-way tables for pairs of behaviors The observed data
log-odds ratio is then expressed as a z-score relative to the expected
data log-odds ratio The z-value is then used as a guide to detect items
that are locally dependent A threshold of plusmn15 was conservatively
chosen as suggestive of local dependence
Next we estimated the probability of transitioning between the
latent stages of marijuana involvement from the 6th through the 9th
grade and the in1047298uence of academic and behavior problem subtypes
on transition rates using latent transition analysis (LTA) LTA is an
extension of latent class analysis to the longitudinal framework which
expresses change over time in terms of transition probabilities and
models the impact of covariates on transitions using a multinomial
logistic regression formulation It has been used extensively to estimate
stage-sequential models of drug use over time (eg Chung Kim
Hipwell amp Stepp 2013 La Flair et al 2013 Lanza amp Bray 2010 Lee
Chassin amp Villalta 2013) We controlled for student-level covariates of
gender free or reduced cost lunch status and intervention status in
the LTA model A robust estimate of the LTA parameter variance that
accounts for the variation due to the estimation of the two sets of LCA
parameters is applied This approach is described in greater technical
detail in the study of Reboussin and Ialongo (2010)

independence assumption via the log-odds ratio residuals for the three
class model indicated that there were no residual dependencies Under
the three-class model that is displayed in Fig 1 61 of youth do not
have academic or behavior problems in the1047297rst grade based on teacher
report and standardized achievement scores Approximately 27 of
youth have high probabilities of falling into the top quartile for opposi-
tionalde1047297ant and aggressive disruptive behaviors as well as having
moderate probabilities of havingattention concentration and academic
problems We refer to this class as the ldquo
externalizing behavior prob-lemsrdquo class because it is primarily dominated by externalizing prob-
lems The least prevalent class (12) was a class of children with high
probabilities of being in the top quartile for attentionconcentration
problems and lowest quartile for both academic achievement and
teacher-reported overall progress We refer to this class as theldquoacadem-
ic and attentionconcentration problemsrdquo class
32 Stages of marijuana involvement longitudinal latent class analysis
Even though a longitudinal latent stage model of the 1047297ve marijuana
involvement behaviors suggested a best 1047297tting one stage model based
on the AIC (1 mdash class = 77395 2 mdash class = 85197 3 mdash class =
115208 4 mdash class = 117893) there was evidence of local dependence
under the one two and three stage models suggesting that additional
stages were necessary to explain the association among the marijuana
behaviors The addition of a fourth stage removed all local dependen-
cies however the prevalence of this fourth stage was only 1 in the
6th grade hindering our ability to obtain stable parameter estimates in
the latent transition models Entropy for the four stage model was also
relatively low (087) suggestive of more classi1047297cation uncertainty com-
pared to the three stage model with entropy of 094 To probe further
whether introductionof a third stage yielded a model that was clinically
meaningful in addition to its ability to improve the local independence
assumption we examined the resultant latent structure to evaluate its
interpretability and clinical meaningfulness and determined this to be
the most appropriate model
As shown in Fig 2 the most prevalent stage is a class with no mari-
juana exposure opportunities or marijuana use We refer to this as the
ldquono marijuana involvementrdquo stage The estimated prevalence of thisstage was 84 in the 6th grade 71 in the 7th grade 56 in the 8th
grade and 38 in the 9th grade The next most prevalent stage is one
in which almost everyone has been offered marijuana but the probabil-
ity of using marijuana is less than 20 We refer to this as the ldquooffered
marijuanardquo stage the prevalence was 14 in the 6th grade 20 in the
7th grade 28 in the 8th grade and 32 in the 9th grade The third
stage is a class of youth who have been offered and used marijuana
(N95) In addition almost 60 have used marijuana more than a
couple of times and almost all youth have experienced social problems
as a result of their marijuana use Just more than 40 have experienced
health problems We refer to this as the ldquomarijuana use and problemsrdquo
stage The prevalence of this stage was 2 in the 6th grade 9 in the
7th grade 16 in the 8th grade and 30 in the 9th grade
33 Transitions between stages of marijuana involvement latent transition
analysis
Asseenin Table 1 the probability of transitioning from no marijuana
involvement to being offered marijuana increases over time and is
signi1047297
cantly greater between the 8th and 9th compared to the 6thand 7th grades (OR = 210 p b 0001) The likelihood of transitioning
from no involvement to use and problems also increases over time
and is signi1047297cantly greater between the 8th and 9th grades (OR =
256 p b 005) and the 7th to 8th grades (OR = 222 p b 005)
compared to the 6th and 7th grades The probability of transitioning
from being offered marijuana to use and problems however is greater
between the 6th and 7th grades compared to between the 7th and 8th
grades (OR = 303 p b 005)
As seen in Table 2 relative to youth with academic and attention
concentration problems at school entry youth with externalizing
behavior problems are more likely to advance from no involvement to
being offered marijuana at entry to high school (ie 9th grade) after
adjustment for gender free and reduced lunch status and intervention
status (AOR = 725 p b 005) They are also more likely to transition
from no marijuana involvement to use and problems between the 7th
and 8th grades relative to youth with no problems (AOR = 1083
p b 005) Youth with academic and attentionconcentration problems
were also more likely to make this transition relative to youth with no
problems between the 7th and 8th grades (AOR = 1069 p b 005)
Youth with academic and attentionconcentration problems were
more likely to advance from being offered marijuana to use and
problems between the 8th and 9th grades relative to youth with no
problems (AOR = 599 p b 005)
4 Discussion
Our results suggest that academic problems occur in combination
with both externalizing and attentionconcentration problems in
African-Americans although to a lesser extent with externalizingproblems In contrast to the work of Reinke et al (2008) that included
both minorities and non-minorities we did not 1047297nd a subtype of
children that were experiencing academic or behavior problems in
isolation Further attention and concentration problems were also
present with moderate probability in the subtype of children with
externalizing behavior problems This is consistent with reports that
African-American youth are more likely to have teachers rate them as
inattentive (DuPaul amp Eckert 1997) and youth from families with
lower socioeconomic status are less likely to be engaged in school
(Smerdon 1999) Our 1047297nding that the subtype of children with exter-
nalizing behavior problems was the most prevalent problem behavior
subtype is also consistent with research that show African-Americans
are more likely than Whites to receive an educational diagnosis of
emotional disturbance (Kaufman 2005) This study demonstrates theneed for future prevention research as well as school services that
focus on the co-occurrence of academic achievement and behavior
problems It also emphasizes the need to intervene early in low income
African-American populations that may be less prepared for school
before this lack of readiness becomes intertwined with classroom
behavior problems setting children off on a path that places them at
risk for marijuana involvement in adolescence
We found that the greatest risk period for making the transition
from no involvement to being offered marijuana was later in middle
school and early in high school This 1047297nding is consistent with Storr
et al (2011) in a similar predominantly African-American urban sample
in which the opportunity to use marijuana rose markedly after the
age of 13 Rates of marijuana use and problems are also increasing
quickly over this time period suggesting a narrow window of

opportunity for prevention during this developmental period Just as
early elementary school is a critical transition period failure to adapt
to the academic and social task demands of middle and high schools
may precipitate ldquodriftrdquo into a deviant peer group wherein a wide
array of antisocial and delinquent behavior including alcohol and
drug use may be reinforced (Brook Nomura amp Cohen 1989 Jessor amp
Jessor 1978 Patterson et al 1992)
Children in the externalizing behavior class in the1047297rst grade were at
greater risk for transitioning from no involvement to being offered
marijuana across all years and signi1047297cantly so between the 8th and
9th grades compared to youth with attentionconcentration problems
This is consistent with the work of Rosenberg and Anthony (2001)who found that aggressive youth are more likely to be approached
with offers to buy drugs This could be theresult of an outward persona
that makes them targets of drug dealers or a greater af 1047297liation with de-
viant peers that are using drugs On the other hand children with
attentionconcentration problems were signi1047297cantly more likely to
transition to use given an opportunity between the 8th and 9th grades
but were not more likely to transition to opportunities This lack of
opportunities (or offers) may be a re1047298ection of rejection by their
peers however given an opportunity to use the impulsivity which
often co-occurs with attentionconcentration problems may cause
them to act without carefully thinking about the consequences of
marijuana use Therefore interventions for those with externalizing
problems may be more peer-focused while interventions for those
with attentionconcentration problems may be more inwardly focused
on strategies for controlling impulsivity Given that the highest risk
period for these transitions is entry into high school strategies for
dealing with the increased academic and social demands of high school
is critical in these problem behavior subgroups in which academic
problems are co-occurring
Limitations of the study should be noted Reliance on self-reported
marijuana use could be subject to underreporting bias however this
study was designed to be sensitive to ethnic-minority populations
with the intent of maximizing participation and minimizing under-
reporting of drug-using behaviors The small number of non-
minorities in the original sample precluded our ability to make anymeaningful (or statistically stable) comparisons between minorities
and non-minorities A larger and more diverse sample may have
allowed not only for ethnic comparisons but identi1047297cation of more
subgroups
Limitations in our sample size may have also hindered our ability to
detect group differences as evidence by a limited number of statistically
signi1047297cant 1047297ndings in the LTA modeling A focus of future work which
we did not consider should be other factors known to be associated
with substance use such as family peer and neighborhood factors
and how they might modify the in1047298uence of academic and problem be-
havior subtypes on transitions in marijuana use in a low-income ethnic
minority population We also caution the reader that the current study
maynot be generalizable to non-urban settings in which early academic

and behavioral pro1047297les school readiness and access to and norms
around marijuana use may differ
Despite these limitations the greatest strength of this study is the
availability of a large sampleof African-Americans participatingin a lon-
gitudinal study designed to be sensitive to ethnic-minority populations
with annualdata collection Prospective studies like this onemdash featuring
a representative cohort of an entire entering class of 1047297rst graders are
relatively rareparticularly bridging the development periods from mid-
dle school to high school Even rarer are prospective studies of African-American youth from neighborhoods that are characterized by high
levels of community violence crime and poverty An understanding
of the ldquosurvivorsrdquo in such an environment canpotentially greatly inform
the next stage of preventive intervention efforts While a larger and
more diverse sample may have allowed the identi1047297cation of more
subgroups cohort differences and ethnic comparisons a community
cohorthas thebene1047297t of identifying within-group differencesin a highly
vulnerable and under-investigated population not always fully cap-
tured in national surveys Our ability to more accurately re1047298ect the
true nature of African-American drug use is what makes this a unique
contribution to the literature
In summary our 1047297ndings highlight the importance of developing
prevention programs and providing school services that address the
co-occurrence of academic and behavior problems as well as their
subtype speci1047297c risks for marijuana involvement particularly for low-
income urban-dwelling African-American youth who may be entering
school less ready than their non-minoritypeers These1047297ndingsalso pro-
vide evidence for a need to continue to deliver interventions in middle
school andhigh school focused on factors that mayprotect youth during
these critical transition periodswhen they may be especially vulnerable
to opportunities to use marijuana based on their academic and behav-
ioral risk pro1047297les

Total Math and Total Reading normal curve equivalent scores for each
child in the 1047297rst grade to create a composite academic achievement
variable The average was then dichotomized to indicate those children
with the most achievement dif 1047297culties (ie bottom 25 on achieve-
ment) In addition to this standardized achievement measure we
included the teacher report of the childs overall progress in the fall of
the 1047297rst grade This item was rated on a 6-point scale (1 = excellent
to 6 = extremely poor) and dichotomized for analyses to indicate
those with poor to extremely poor progress versus those with good toexcellent progress
223 Marijuana involvement in 6th 7th 8th and 9th grades
We considered responses to1047297ve questions about marijuana involve-
ment gathered in the spring of the 6th 7th 8th and 9th grades Oppor-
tunity to usemarijuanainvolved askingwhether a youth hadldquoever been
offeredrdquo marijuana as described by Crum Lillie-Blanton and Anthony
(1996) Adolescent reports of marijuana use were based on asking
ldquoHave you ever used marijuanardquo Frequency of marijuana use was
measured based on questions from the Monitoring the Future survey
( Johnston OMalley amp Bachman 1995) and was de1047297ned as ever using
marijuana more than a couple of times ie on three or more occasions
This low threshold for frequent marijuana use was chosen to be
meaningful for this sample of young adolescents It also gave us the
opportunity to explore whether this level of use is problematic in
young adolescents For this reason we also looked at health and social
problems associated with marijuana use Health and social problems
were assessed by asking if they ever experienced any health problems
or social problems from using marijuana The speci1047297c problems
comprising these two questions are listed in Appendix A
224 Demographic information
The school district provided information on the students sex and
ethnicity School records indicating each students free or reduced-cost
meal status were collapsed into a dichotomous variable of free or
reduced lunch versus self-paid lunch as an indicator of students
socioeconomic status
23 Statistical analyses
A cross-sectional latent class analysis (LCA) was applied to examine
the structure underlying the 1047297ve indicators of academic and behavior
problems in the 1047297rst grade The basic premise of LCA is that within
classes behaviors are locally independent (Lazarsfeld 1950) The goal
is to identify the smallest number of classes that adequately describes
the association among the behaviors Information about the resultant
class structure is conveyed through two sets of parameters the
probability of having high levels of academic andor behavior problems
within a particular class (item probabilities) and the proportion of
youth in each class (class prevalences)
A longitudinal latent class model (or latent stage model) was then
applied to examine the structure underlying the 1047297ve items comprising
the marijuana involvement pro1047297le over time While in principle it ispossible to allow the item probabilities and hence latent structure to
vary over time forthe 6thto 9th grade marijuana indicators this implies
that the de1047297nition of marijuana involvement is changing which would
substantially complicate the interpretation of a longitudinal model
Therefore we constrained the item probabilities to be constant over
time ie the probability of reporting a behavior within a latent stage
was thesame in each grade This is analogous to constraining the factor
loadings to be equal over time in a longitudinal factor analysis model
(sometimes referred to as factor invariance) The latent stage preva-
lences however were allowed to vary over time ie the proportion of
youth in each stage could change over time
Our model building strategy for the two sets of latent class models
involved starting with the most parsimonious one-class (or one-stage)
model and 1047297tting successive models with an increasing number of
latent classes (or stages) in order to determine the most parsimonious
model that provided an adequate 1047297t to the data The goodness-of-1047297t of
various models was evaluated using the Akaikes Information Criteria
(AIC) a global 1047297t index that combines goodness-of-1047297t and parsimony
Because we were concerned that the statistical power in this study
may be limited by the sample size we chose to rely on the AIC over
other global 1047297t indices as it is known to favor more complex models
(Lin amp Dayton 1997) Entropy was calculated to provide an indication
of the overall degree of classi1047297
cation uncertainty in the solution(Celeuxamp Soromenho 1996) Lower valuesof AIC are preferable where-
as higher values (or values closer to 1) are better for entropy For latent
class models there are considerations other than global goodness-of-1047297t
indices In particular an examination of thevalidityof thelocal indepen-
dence assumption which is the hallmark of LCA is critical We used a
modi1047297ed version of Garrett and Zegers (2000) Log-Odds Ratio Check
This method involves calculating thelog-oddsratio in both theobserved
and expected two-way tables for pairs of behaviors The observed data
log-odds ratio is then expressed as a z-score relative to the expected
data log-odds ratio The z-value is then used as a guide to detect items
that are locally dependent A threshold of plusmn15 was conservatively
chosen as suggestive of local dependence
Next we estimated the probability of transitioning between the
latent stages of marijuana involvement from the 6th through the 9th
grade and the in1047298uence of academic and behavior problem subtypes
on transition rates using latent transition analysis (LTA) LTA is an
extension of latent class analysis to the longitudinal framework which
expresses change over time in terms of transition probabilities and
models the impact of covariates on transitions using a multinomial
logistic regression formulation It has been used extensively to estimate
stage-sequential models of drug use over time (eg Chung Kim
Hipwell amp Stepp 2013 La Flair et al 2013 Lanza amp Bray 2010 Lee
Chassin amp Villalta 2013) We controlled for student-level covariates of
gender free or reduced cost lunch status and intervention status in
the LTA model A robust estimate of the LTA parameter variance that
accounts for the variation due to the estimation of the two sets of LCA
parameters is applied This approach is described in greater technical
detail in the study of Reboussin and Ialongo (2010)

independence assumption via the log-odds ratio residuals for the three
class model indicated that there were no residual dependencies Under
the three-class model that is displayed in Fig 1 61 of youth do not
have academic or behavior problems in the1047297rst grade based on teacher
report and standardized achievement scores Approximately 27 of
youth have high probabilities of falling into the top quartile for opposi-
tionalde1047297ant and aggressive disruptive behaviors as well as having
moderate probabilities of havingattention concentration and academic
problems We refer to this class as the ldquo
externalizing behavior prob-lemsrdquo class because it is primarily dominated by externalizing prob-
lems The least prevalent class (12) was a class of children with high
probabilities of being in the top quartile for attentionconcentration
problems and lowest quartile for both academic achievement and
teacher-reported overall progress We refer to this class as theldquoacadem-
ic and attentionconcentration problemsrdquo class
32 Stages of marijuana involvement longitudinal latent class analysis
Even though a longitudinal latent stage model of the 1047297ve marijuana
involvement behaviors suggested a best 1047297tting one stage model based
on the AIC (1 mdash class = 77395 2 mdash class = 85197 3 mdash class =
115208 4 mdash class = 117893) there was evidence of local dependence
under the one two and three stage models suggesting that additional
stages were necessary to explain the association among the marijuana
behaviors The addition of a fourth stage removed all local dependen-
cies however the prevalence of this fourth stage was only 1 in the
6th grade hindering our ability to obtain stable parameter estimates in
the latent transition models Entropy for the four stage model was also
relatively low (087) suggestive of more classi1047297cation uncertainty com-
pared to the three stage model with entropy of 094 To probe further
whether introductionof a third stage yielded a model that was clinically
meaningful in addition to its ability to improve the local independence
assumption we examined the resultant latent structure to evaluate its
interpretability and clinical meaningfulness and determined this to be
the most appropriate model
As shown in Fig 2 the most prevalent stage is a class with no mari-
juana exposure opportunities or marijuana use We refer to this as the
ldquono marijuana involvementrdquo stage The estimated prevalence of thisstage was 84 in the 6th grade 71 in the 7th grade 56 in the 8th
grade and 38 in the 9th grade The next most prevalent stage is one
in which almost everyone has been offered marijuana but the probabil-
ity of using marijuana is less than 20 We refer to this as the ldquooffered
marijuanardquo stage the prevalence was 14 in the 6th grade 20 in the
7th grade 28 in the 8th grade and 32 in the 9th grade The third
stage is a class of youth who have been offered and used marijuana
(N95) In addition almost 60 have used marijuana more than a
couple of times and almost all youth have experienced social problems
as a result of their marijuana use Just more than 40 have experienced
health problems We refer to this as the ldquomarijuana use and problemsrdquo
stage The prevalence of this stage was 2 in the 6th grade 9 in the
7th grade 16 in the 8th grade and 30 in the 9th grade
33 Transitions between stages of marijuana involvement latent transition
analysis
Asseenin Table 1 the probability of transitioning from no marijuana
involvement to being offered marijuana increases over time and is
signi1047297
cantly greater between the 8th and 9th compared to the 6thand 7th grades (OR = 210 p b 0001) The likelihood of transitioning
from no involvement to use and problems also increases over time
and is signi1047297cantly greater between the 8th and 9th grades (OR =
256 p b 005) and the 7th to 8th grades (OR = 222 p b 005)
compared to the 6th and 7th grades The probability of transitioning
from being offered marijuana to use and problems however is greater
between the 6th and 7th grades compared to between the 7th and 8th
grades (OR = 303 p b 005)
As seen in Table 2 relative to youth with academic and attention
concentration problems at school entry youth with externalizing
behavior problems are more likely to advance from no involvement to
being offered marijuana at entry to high school (ie 9th grade) after
adjustment for gender free and reduced lunch status and intervention
status (AOR = 725 p b 005) They are also more likely to transition
from no marijuana involvement to use and problems between the 7th
and 8th grades relative to youth with no problems (AOR = 1083
p b 005) Youth with academic and attentionconcentration problems
were also more likely to make this transition relative to youth with no
problems between the 7th and 8th grades (AOR = 1069 p b 005)
Youth with academic and attentionconcentration problems were
more likely to advance from being offered marijuana to use and
problems between the 8th and 9th grades relative to youth with no
problems (AOR = 599 p b 005)
4 Discussion
Our results suggest that academic problems occur in combination
with both externalizing and attentionconcentration problems in
African-Americans although to a lesser extent with externalizingproblems In contrast to the work of Reinke et al (2008) that included
both minorities and non-minorities we did not 1047297nd a subtype of
children that were experiencing academic or behavior problems in
isolation Further attention and concentration problems were also
present with moderate probability in the subtype of children with
externalizing behavior problems This is consistent with reports that
African-American youth are more likely to have teachers rate them as
inattentive (DuPaul amp Eckert 1997) and youth from families with
lower socioeconomic status are less likely to be engaged in school
(Smerdon 1999) Our 1047297nding that the subtype of children with exter-
nalizing behavior problems was the most prevalent problem behavior
subtype is also consistent with research that show African-Americans
are more likely than Whites to receive an educational diagnosis of
emotional disturbance (Kaufman 2005) This study demonstrates theneed for future prevention research as well as school services that
focus on the co-occurrence of academic achievement and behavior
problems It also emphasizes the need to intervene early in low income
African-American populations that may be less prepared for school
before this lack of readiness becomes intertwined with classroom
behavior problems setting children off on a path that places them at
risk for marijuana involvement in adolescence
We found that the greatest risk period for making the transition
from no involvement to being offered marijuana was later in middle
school and early in high school This 1047297nding is consistent with Storr
et al (2011) in a similar predominantly African-American urban sample
in which the opportunity to use marijuana rose markedly after the
age of 13 Rates of marijuana use and problems are also increasing
quickly over this time period suggesting a narrow window of

opportunity for prevention during this developmental period Just as
early elementary school is a critical transition period failure to adapt
to the academic and social task demands of middle and high schools
may precipitate ldquodriftrdquo into a deviant peer group wherein a wide
array of antisocial and delinquent behavior including alcohol and
drug use may be reinforced (Brook Nomura amp Cohen 1989 Jessor amp
Jessor 1978 Patterson et al 1992)
Children in the externalizing behavior class in the1047297rst grade were at
greater risk for transitioning from no involvement to being offered
marijuana across all years and signi1047297cantly so between the 8th and
9th grades compared to youth with attentionconcentration problems
This is consistent with the work of Rosenberg and Anthony (2001)who found that aggressive youth are more likely to be approached
with offers to buy drugs This could be theresult of an outward persona
that makes them targets of drug dealers or a greater af 1047297liation with de-
viant peers that are using drugs On the other hand children with
attentionconcentration problems were signi1047297cantly more likely to
transition to use given an opportunity between the 8th and 9th grades
but were not more likely to transition to opportunities This lack of
opportunities (or offers) may be a re1047298ection of rejection by their
peers however given an opportunity to use the impulsivity which
often co-occurs with attentionconcentration problems may cause
them to act without carefully thinking about the consequences of
marijuana use Therefore interventions for those with externalizing
problems may be more peer-focused while interventions for those
with attentionconcentration problems may be more inwardly focused
on strategies for controlling impulsivity Given that the highest risk
period for these transitions is entry into high school strategies for
dealing with the increased academic and social demands of high school
is critical in these problem behavior subgroups in which academic
problems are co-occurring
Limitations of the study should be noted Reliance on self-reported
marijuana use could be subject to underreporting bias however this
study was designed to be sensitive to ethnic-minority populations
with the intent of maximizing participation and minimizing under-
reporting of drug-using behaviors The small number of non-
minorities in the original sample precluded our ability to make anymeaningful (or statistically stable) comparisons between minorities
and non-minorities A larger and more diverse sample may have
allowed not only for ethnic comparisons but identi1047297cation of more
subgroups
Limitations in our sample size may have also hindered our ability to
detect group differences as evidence by a limited number of statistically
signi1047297cant 1047297ndings in the LTA modeling A focus of future work which
we did not consider should be other factors known to be associated
with substance use such as family peer and neighborhood factors
and how they might modify the in1047298uence of academic and problem be-
havior subtypes on transitions in marijuana use in a low-income ethnic
minority population We also caution the reader that the current study
maynot be generalizable to non-urban settings in which early academic

around marijuana use may differ
Despite these limitations the greatest strength of this study is the
availability of a large sampleof African-Americans participatingin a lon-
gitudinal study designed to be sensitive to ethnic-minority populations
with annualdata collection Prospective studies like this onemdash featuring
a representative cohort of an entire entering class of 1047297rst graders are
relatively rareparticularly bridging the development periods from mid-
dle school to high school Even rarer are prospective studies of African-American youth from neighborhoods that are characterized by high
levels of community violence crime and poverty An understanding
of the ldquosurvivorsrdquo in such an environment canpotentially greatly inform
the next stage of preventive intervention efforts While a larger and
more diverse sample may have allowed the identi1047297cation of more
subgroups cohort differences and ethnic comparisons a community
cohorthas thebene1047297t of identifying within-group differencesin a highly
vulnerable and under-investigated population not always fully cap-
tured in national surveys Our ability to more accurately re1047298ect the
true nature of African-American drug use is what makes this a unique
contribution to the literature
In summary our 1047297ndings highlight the importance of developing
prevention programs and providing school services that address the
co-occurrence of academic and behavior problems as well as their
subtype speci1047297c risks for marijuana involvement particularly for low-
income urban-dwelling African-American youth who may be entering
school less ready than their non-minoritypeers These1047297ndingsalso pro-
vide evidence for a need to continue to deliver interventions in middle
school andhigh school focused on factors that mayprotect youth during
these critical transition periodswhen they may be especially vulnerable

child in the 1047297rst grade to create a composite academic achievement
variable The average was then dichotomized to indicate those children
with the most achievement dif 1047297culties (ie bottom 25 on achieve-
ment) In addition to this standardized achievement measure we
included the teacher report of the childs overall progress in the fall of

223 Marijuana involvement in 6th 7th 8th and 9th grades
We considered responses to1047297ve questions about marijuana involve-
ment gathered in the spring of the 6th 7th 8th and 9th grades Oppor-
tunity to usemarijuanainvolved askingwhether a youth hadldquoever been
offeredrdquo marijuana as described by Crum Lillie-Blanton and Anthony
(1996) Adolescent reports of marijuana use were based on asking
ldquoHave you ever used marijuanardquo Frequency of marijuana use was
measured based on questions from the Monitoring the Future survey
( Johnston OMalley amp Bachman 1995) and was de1047297ned as ever using
marijuana more than a couple of times ie on three or more occasions
This low threshold for frequent marijuana use was chosen to be
meaningful for this sample of young adolescents It also gave us the
opportunity to explore whether this level of use is problematic in
young adolescents For this reason we also looked at health and social
problems associated with marijuana use Health and social problems
were assessed by asking if they ever experienced any health problems
or social problems from using marijuana The speci1047297c problems
comprising these two questions are listed in Appendix A
224 Demographic information
The school district provided information on the students sex and
ethnicity School records indicating each students free or reduced-cost
meal status were collapsed into a dichotomous variable of free or
reduced lunch versus self-paid lunch as an indicator of students
socioeconomic status
23 Statistical analyses
A cross-sectional latent class analysis (LCA) was applied to examine
the structure underlying the 1047297ve indicators of academic and behavior
problems in the 1047297rst grade The basic premise of LCA is that within
classes behaviors are locally independent (Lazarsfeld 1950) The goal
is to identify the smallest number of classes that adequately describes
the association among the behaviors Information about the resultant
class structure is conveyed through two sets of parameters the
probability of having high levels of academic andor behavior problems
within a particular class (item probabilities) and the proportion of
youth in each class (class prevalences)
A longitudinal latent class model (or latent stage model) was then
applied to examine the structure underlying the 1047297ve items comprising
the marijuana involvement pro1047297le over time While in principle it ispossible to allow the item probabilities and hence latent structure to
vary over time forthe 6thto 9th grade marijuana indicators this implies
that the de1047297nition of marijuana involvement is changing which would
substantially complicate the interpretation of a longitudinal model
Therefore we constrained the item probabilities to be constant over
time ie the probability of reporting a behavior within a latent stage
was thesame in each grade This is analogous to constraining the factor
loadings to be equal over time in a longitudinal factor analysis model
(sometimes referred to as factor invariance) The latent stage preva-
lences however were allowed to vary over time ie the proportion of
youth in each stage could change over time
Our model building strategy for the two sets of latent class models
involved starting with the most parsimonious one-class (or one-stage)
model and 1047297tting successive models with an increasing number of
latent classes (or stages) in order to determine the most parsimonious
model that provided an adequate 1047297t to the data The goodness-of-1047297t of
various models was evaluated using the Akaikes Information Criteria
(AIC) a global 1047297t index that combines goodness-of-1047297t and parsimony
Because we were concerned that the statistical power in this study
may be limited by the sample size we chose to rely on the AIC over
other global 1047297t indices as it is known to favor more complex models
(Lin amp Dayton 1997) Entropy was calculated to provide an indication
of the overall degree of classi1047297
cation uncertainty in the solution(Celeuxamp Soromenho 1996) Lower valuesof AIC are preferable where-
as higher values (or values closer to 1) are better for entropy For latent
class models there are considerations other than global goodness-of-1047297t
indices In particular an examination of thevalidityof thelocal indepen-
dence assumption which is the hallmark of LCA is critical We used a
modi1047297ed version of Garrett and Zegers (2000) Log-Odds Ratio Check
This method involves calculating thelog-oddsratio in both theobserved
and expected two-way tables for pairs of behaviors The observed data
log-odds ratio is then expressed as a z-score relative to the expected
data log-odds ratio The z-value is then used as a guide to detect items
that are locally dependent A threshold of plusmn15 was conservatively
chosen as suggestive of local dependence
Next we estimated the probability of transitioning between the
latent stages of marijuana involvement from the 6th through the 9th
grade and the in1047298uence of academic and behavior problem subtypes
on transition rates using latent transition analysis (LTA) LTA is an
extension of latent class analysis to the longitudinal framework which
expresses change over time in terms of transition probabilities and
models the impact of covariates on transitions using a multinomial
logistic regression formulation It has been used extensively to estimate
stage-sequential models of drug use over time (eg Chung Kim
Hipwell amp Stepp 2013 La Flair et al 2013 Lanza amp Bray 2010 Lee
Chassin amp Villalta 2013) We controlled for student-level covariates of
gender free or reduced cost lunch status and intervention status in
the LTA model A robust estimate of the LTA parameter variance that
accounts for the variation due to the estimation of the two sets of LCA
parameters is applied This approach is described in greater technical
detail in the study of Reboussin and Ialongo (2010)

independence assumption via the log-odds ratio residuals for the three
class model indicated that there were no residual dependencies Under
the three-class model that is displayed in Fig 1 61 of youth do not
have academic or behavior problems in the1047297rst grade based on teacher
report and standardized achievement scores Approximately 27 of
youth have high probabilities of falling into the top quartile for opposi-
tionalde1047297ant and aggressive disruptive behaviors as well as having
moderate probabilities of havingattention concentration and academic
problems We refer to this class as the ldquo
externalizing behavior prob-lemsrdquo class because it is primarily dominated by externalizing prob-
lems The least prevalent class (12) was a class of children with high
probabilities of being in the top quartile for attentionconcentration
problems and lowest quartile for both academic achievement and
teacher-reported overall progress We refer to this class as theldquoacadem-
ic and attentionconcentration problemsrdquo class
32 Stages of marijuana involvement longitudinal latent class analysis
Even though a longitudinal latent stage model of the 1047297ve marijuana
involvement behaviors suggested a best 1047297tting one stage model based
on the AIC (1 mdash class = 77395 2 mdash class = 85197 3 mdash class =
115208 4 mdash class = 117893) there was evidence of local dependence
under the one two and three stage models suggesting that additional
stages were necessary to explain the association among the marijuana
behaviors The addition of a fourth stage removed all local dependen-
cies however the prevalence of this fourth stage was only 1 in the
6th grade hindering our ability to obtain stable parameter estimates in
the latent transition models Entropy for the four stage model was also
relatively low (087) suggestive of more classi1047297cation uncertainty com-
pared to the three stage model with entropy of 094 To probe further
whether introductionof a third stage yielded a model that was clinically
meaningful in addition to its ability to improve the local independence
assumption we examined the resultant latent structure to evaluate its
interpretability and clinical meaningfulness and determined this to be
the most appropriate model
As shown in Fig 2 the most prevalent stage is a class with no mari-
juana exposure opportunities or marijuana use We refer to this as the
ldquono marijuana involvementrdquo stage The estimated prevalence of thisstage was 84 in the 6th grade 71 in the 7th grade 56 in the 8th
grade and 38 in the 9th grade The next most prevalent stage is one
in which almost everyone has been offered marijuana but the probabil-
ity of using marijuana is less than 20 We refer to this as the ldquooffered
marijuanardquo stage the prevalence was 14 in the 6th grade 20 in the
7th grade 28 in the 8th grade and 32 in the 9th grade The third
stage is a class of youth who have been offered and used marijuana
(N95) In addition almost 60 have used marijuana more than a
couple of times and almost all youth have experienced social problems
as a result of their marijuana use Just more than 40 have experienced
health problems We refer to this as the ldquomarijuana use and problemsrdquo
stage The prevalence of this stage was 2 in the 6th grade 9 in the
7th grade 16 in the 8th grade and 30 in the 9th grade
33 Transitions between stages of marijuana involvement latent transition
analysis
Asseenin Table 1 the probability of transitioning from no marijuana
involvement to being offered marijuana increases over time and is
signi1047297
cantly greater between the 8th and 9th compared to the 6thand 7th grades (OR = 210 p b 0001) The likelihood of transitioning
from no involvement to use and problems also increases over time
and is signi1047297cantly greater between the 8th and 9th grades (OR =
256 p b 005) and the 7th to 8th grades (OR = 222 p b 005)
compared to the 6th and 7th grades The probability of transitioning
from being offered marijuana to use and problems however is greater
between the 6th and 7th grades compared to between the 7th and 8th
grades (OR = 303 p b 005)
As seen in Table 2 relative to youth with academic and attention
concentration problems at school entry youth with externalizing
behavior problems are more likely to advance from no involvement to
being offered marijuana at entry to high school (ie 9th grade) after
adjustment for gender free and reduced lunch status and intervention
status (AOR = 725 p b 005) They are also more likely to transition
from no marijuana involvement to use and problems between the 7th
and 8th grades relative to youth with no problems (AOR = 1083
p b 005) Youth with academic and attentionconcentration problems
were also more likely to make this transition relative to youth with no
problems between the 7th and 8th grades (AOR = 1069 p b 005)
Youth with academic and attentionconcentration problems were
more likely to advance from being offered marijuana to use and
problems between the 8th and 9th grades relative to youth with no
problems (AOR = 599 p b 005)
4 Discussion
Our results suggest that academic problems occur in combination
with both externalizing and attentionconcentration problems in
African-Americans although to a lesser extent with externalizingproblems In contrast to the work of Reinke et al (2008) that included
both minorities and non-minorities we did not 1047297nd a subtype of
children that were experiencing academic or behavior problems in
isolation Further attention and concentration problems were also
present with moderate probability in the subtype of children with
externalizing behavior problems This is consistent with reports that
African-American youth are more likely to have teachers rate them as
inattentive (DuPaul amp Eckert 1997) and youth from families with
lower socioeconomic status are less likely to be engaged in school
(Smerdon 1999) Our 1047297nding that the subtype of children with exter-
nalizing behavior problems was the most prevalent problem behavior
subtype is also consistent with research that show African-Americans
are more likely than Whites to receive an educational diagnosis of
emotional disturbance (Kaufman 2005) This study demonstrates theneed for future prevention research as well as school services that
focus on the co-occurrence of academic achievement and behavior
problems It also emphasizes the need to intervene early in low income
African-American populations that may be less prepared for school
before this lack of readiness becomes intertwined with classroom
behavior problems setting children off on a path that places them at
risk for marijuana involvement in adolescence
We found that the greatest risk period for making the transition
from no involvement to being offered marijuana was later in middle
school and early in high school This 1047297nding is consistent with Storr
et al (2011) in a similar predominantly African-American urban sample
in which the opportunity to use marijuana rose markedly after the
age of 13 Rates of marijuana use and problems are also increasing
quickly over this time period suggesting a narrow window of

opportunity for prevention during this developmental period Just as
early elementary school is a critical transition period failure to adapt
to the academic and social task demands of middle and high schools
may precipitate ldquodriftrdquo into a deviant peer group wherein a wide
array of antisocial and delinquent behavior including alcohol and
drug use may be reinforced (Brook Nomura amp Cohen 1989 Jessor amp
Jessor 1978 Patterson et al 1992)
Children in the externalizing behavior class in the1047297rst grade were at
greater risk for transitioning from no involvement to being offered
marijuana across all years and signi1047297cantly so between the 8th and
9th grades compared to youth with attentionconcentration problems
This is consistent with the work of Rosenberg and Anthony (2001)who found that aggressive youth are more likely to be approached
with offers to buy drugs This could be theresult of an outward persona
that makes them targets of drug dealers or a greater af 1047297liation with de-
viant peers that are using drugs On the other hand children with
attentionconcentration problems were signi1047297cantly more likely to
transition to use given an opportunity between the 8th and 9th grades
but were not more likely to transition to opportunities This lack of
opportunities (or offers) may be a re1047298ection of rejection by their
peers however given an opportunity to use the impulsivity which
often co-occurs with attentionconcentration problems may cause
them to act without carefully thinking about the consequences of
marijuana use Therefore interventions for those with externalizing
problems may be more peer-focused while interventions for those
with attentionconcentration problems may be more inwardly focused
on strategies for controlling impulsivity Given that the highest risk
period for these transitions is entry into high school strategies for
dealing with the increased academic and social demands of high school
is critical in these problem behavior subgroups in which academic
problems are co-occurring
Limitations of the study should be noted Reliance on self-reported
marijuana use could be subject to underreporting bias however this
study was designed to be sensitive to ethnic-minority populations
with the intent of maximizing participation and minimizing under-
reporting of drug-using behaviors The small number of non-
minorities in the original sample precluded our ability to make anymeaningful (or statistically stable) comparisons between minorities
and non-minorities A larger and more diverse sample may have
allowed not only for ethnic comparisons but identi1047297cation of more
subgroups
Limitations in our sample size may have also hindered our ability to
detect group differences as evidence by a limited number of statistically
signi1047297cant 1047297ndings in the LTA modeling A focus of future work which

around marijuana use may differ
Despite these limitations the greatest strength of this study is the
availability of a large sampleof African-Americans participatingin a lon-
gitudinal study designed to be sensitive to ethnic-minority populations
with annualdata collection Prospective studies like this onemdash featuring
a representative cohort of an entire entering class of 1047297rst graders are
relatively rareparticularly bridging the development periods from mid-
dle school to high school Even rarer are prospective studies of African-American youth from neighborhoods that are characterized by high
levels of community violence crime and poverty An understanding
of the ldquosurvivorsrdquo in such an environment canpotentially greatly inform
the next stage of preventive intervention efforts While a larger and
more diverse sample may have allowed the identi1047297cation of more
subgroups cohort differences and ethnic comparisons a community

vulnerable and under-investigated population not always fully cap-
tured in national surveys Our ability to more accurately re1047298ect the
true nature of African-American drug use is what makes this a unique
contribution to the literature
In summary our 1047297ndings highlight the importance of developing
prevention programs and providing school services that address the
co-occurrence of academic and behavior problems as well as their
subtype speci1047297c risks for marijuana involvement particularly for low-
income urban-dwelling African-American youth who may be entering
school less ready than their non-minoritypeers These1047297ndingsalso pro-

these critical transition periodswhen they may be especially vulnerable

independence assumption via the log-odds ratio residuals for the three
class model indicated that there were no residual dependencies Under
the three-class model that is displayed in Fig 1 61 of youth do not
have academic or behavior problems in the1047297rst grade based on teacher
report and standardized achievement scores Approximately 27 of
youth have high probabilities of falling into the top quartile for opposi-
tionalde1047297ant and aggressive disruptive behaviors as well as having
moderate probabilities of havingattention concentration and academic
problems We refer to this class as the ldquo
externalizing behavior prob-lemsrdquo class because it is primarily dominated by externalizing prob-
lems The least prevalent class (12) was a class of children with high
probabilities of being in the top quartile for attentionconcentration
problems and lowest quartile for both academic achievement and
teacher-reported overall progress We refer to this class as theldquoacadem-
ic and attentionconcentration problemsrdquo class
32 Stages of marijuana involvement longitudinal latent class analysis
Even though a longitudinal latent stage model of the 1047297ve marijuana
involvement behaviors suggested a best 1047297tting one stage model based
on the AIC (1 mdash class = 77395 2 mdash class = 85197 3 mdash class =
115208 4 mdash class = 117893) there was evidence of local dependence
under the one two and three stage models suggesting that additional
stages were necessary to explain the association among the marijuana
behaviors The addition of a fourth stage removed all local dependen-
cies however the prevalence of this fourth stage was only 1 in the
6th grade hindering our ability to obtain stable parameter estimates in
the latent transition models Entropy for the four stage model was also
relatively low (087) suggestive of more classi1047297cation uncertainty com-
pared to the three stage model with entropy of 094 To probe further
whether introductionof a third stage yielded a model that was clinically
meaningful in addition to its ability to improve the local independence
assumption we examined the resultant latent structure to evaluate its
interpretability and clinical meaningfulness and determined this to be
the most appropriate model
As shown in Fig 2 the most prevalent stage is a class with no mari-
juana exposure opportunities or marijuana use We refer to this as the
ldquono marijuana involvementrdquo stage The estimated prevalence of thisstage was 84 in the 6th grade 71 in the 7th grade 56 in the 8th
grade and 38 in the 9th grade The next most prevalent stage is one
in which almost everyone has been offered marijuana but the probabil-
ity of using marijuana is less than 20 We refer to this as the ldquooffered
marijuanardquo stage the prevalence was 14 in the 6th grade 20 in the
7th grade 28 in the 8th grade and 32 in the 9th grade The third
stage is a class of youth who have been offered and used marijuana
(N95) In addition almost 60 have used marijuana more than a
couple of times and almost all youth have experienced social problems
as a result of their marijuana use Just more than 40 have experienced
health problems We refer to this as the ldquomarijuana use and problemsrdquo
stage The prevalence of this stage was 2 in the 6th grade 9 in the
7th grade 16 in the 8th grade and 30 in the 9th grade
33 Transitions between stages of marijuana involvement latent transition
analysis
Asseenin Table 1 the probability of transitioning from no marijuana
involvement to being offered marijuana increases over time and is
signi1047297
cantly greater between the 8th and 9th compared to the 6thand 7th grades (OR = 210 p b 0001) The likelihood of transitioning
from no involvement to use and problems also increases over time
and is signi1047297cantly greater between the 8th and 9th grades (OR =
256 p b 005) and the 7th to 8th grades (OR = 222 p b 005)
compared to the 6th and 7th grades The probability of transitioning
from being offered marijuana to use and problems however is greater
between the 6th and 7th grades compared to between the 7th and 8th
grades (OR = 303 p b 005)
As seen in Table 2 relative to youth with academic and attention
concentration problems at school entry youth with externalizing
behavior problems are more likely to advance from no involvement to
being offered marijuana at entry to high school (ie 9th grade) after
adjustment for gender free and reduced lunch status and intervention
status (AOR = 725 p b 005) They are also more likely to transition
from no marijuana involvement to use and problems between the 7th
and 8th grades relative to youth with no problems (AOR = 1083
p b 005) Youth with academic and attentionconcentration problems
were also more likely to make this transition relative to youth with no
problems between the 7th and 8th grades (AOR = 1069 p b 005)
Youth with academic and attentionconcentration problems were
more likely to advance from being offered marijuana to use and
problems between the 8th and 9th grades relative to youth with no
problems (AOR = 599 p b 005)
4 Discussion
Our results suggest that academic problems occur in combination
with both externalizing and attentionconcentration problems in
African-Americans although to a lesser extent with externalizingproblems In contrast to the work of Reinke et al (2008) that included
both minorities and non-minorities we did not 1047297nd a subtype of
children that were experiencing academic or behavior problems in
isolation Further attention and concentration problems were also
present with moderate probability in the subtype of children with
externalizing behavior problems This is consistent with reports that
African-American youth are more likely to have teachers rate them as
inattentive (DuPaul amp Eckert 1997) and youth from families with
lower socioeconomic status are less likely to be engaged in school
(Smerdon 1999) Our 1047297nding that the subtype of children with exter-
nalizing behavior problems was the most prevalent problem behavior
subtype is also consistent with research that show African-Americans
are more likely than Whites to receive an educational diagnosis of
emotional disturbance (Kaufman 2005) This study demonstrates theneed for future prevention research as well as school services that
focus on the co-occurrence of academic achievement and behavior
problems It also emphasizes the need to intervene early in low income
African-American populations that may be less prepared for school
before this lack of readiness becomes intertwined with classroom
behavior problems setting children off on a path that places them at
risk for marijuana involvement in adolescence
We found that the greatest risk period for making the transition
from no involvement to being offered marijuana was later in middle
school and early in high school This 1047297nding is consistent with Storr
et al (2011) in a similar predominantly African-American urban sample
in which the opportunity to use marijuana rose markedly after the
age of 13 Rates of marijuana use and problems are also increasing
quickly over this time period suggesting a narrow window of

opportunity for prevention during this developmental period Just as
early elementary school is a critical transition period failure to adapt
to the academic and social task demands of middle and high schools
may precipitate ldquodriftrdquo into a deviant peer group wherein a wide
array of antisocial and delinquent behavior including alcohol and
drug use may be reinforced (Brook Nomura amp Cohen 1989 Jessor amp
Jessor 1978 Patterson et al 1992)
Children in the externalizing behavior class in the1047297rst grade were at
greater risk for transitioning from no involvement to being offered
marijuana across all years and signi1047297cantly so between the 8th and
9th grades compared to youth with attentionconcentration problems
This is consistent with the work of Rosenberg and Anthony (2001)who found that aggressive youth are more likely to be approached
with offers to buy drugs This could be theresult of an outward persona
that makes them targets of drug dealers or a greater af 1047297liation with de-
viant peers that are using drugs On the other hand children with
attentionconcentration problems were signi1047297cantly more likely to
transition to use given an opportunity between the 8th and 9th grades
but were not more likely to transition to opportunities This lack of
opportunities (or offers) may be a re1047298ection of rejection by their
peers however given an opportunity to use the impulsivity which
often co-occurs with attentionconcentration problems may cause
them to act without carefully thinking about the consequences of
marijuana use Therefore interventions for those with externalizing
problems may be more peer-focused while interventions for those
with attentionconcentration problems may be more inwardly focused
on strategies for controlling impulsivity Given that the highest risk
period for these transitions is entry into high school strategies for
dealing with the increased academic and social demands of high school
is critical in these problem behavior subgroups in which academic
problems are co-occurring
Limitations of the study should be noted Reliance on self-reported
marijuana use could be subject to underreporting bias however this
study was designed to be sensitive to ethnic-minority populations
with the intent of maximizing participation and minimizing under-
reporting of drug-using behaviors The small number of non-
minorities in the original sample precluded our ability to make anymeaningful (or statistically stable) comparisons between minorities
and non-minorities A larger and more diverse sample may have
allowed not only for ethnic comparisons but identi1047297cation of more
subgroups
Limitations in our sample size may have also hindered our ability to
detect group differences as evidence by a limited number of statistically
signi1047297cant 1047297ndings in the LTA modeling A focus of future work which
we did not consider should be other factors known to be associated
with substance use such as family peer and neighborhood factors
and how they might modify the in1047298uence of academic and problem be-
havior subtypes on transitions in marijuana use in a low-income ethnic
minority population We also caution the reader that the current study
maynot be generalizable to non-urban settings in which early academic

opportunity for prevention during this developmental period Just as
early elementary school is a critical transition period failure to adapt
to the academic and social task demands of middle and high schools
may precipitate ldquodriftrdquo into a deviant peer group wherein a wide
array of antisocial and delinquent behavior including alcohol and
drug use may be reinforced (Brook Nomura amp Cohen 1989 Jessor amp
Jessor 1978 Patterson et al 1992)
Children in the externalizing behavior class in the1047297rst grade were at
greater risk for transitioning from no involvement to being offered
marijuana across all years and signi1047297cantly so between the 8th and
9th grades compared to youth with attentionconcentration problems
This is consistent with the work of Rosenberg and Anthony (2001)who found that aggressive youth are more likely to be approached
with offers to buy drugs This could be theresult of an outward persona
that makes them targets of drug dealers or a greater af 1047297liation with de-
viant peers that are using drugs On the other hand children with
attentionconcentration problems were signi1047297cantly more likely to
transition to use given an opportunity between the 8th and 9th grades
but were not more likely to transition to opportunities This lack of
opportunities (or offers) may be a re1047298ection of rejection by their
peers however given an opportunity to use the impulsivity which
often co-occurs with attentionconcentration problems may cause
them to act without carefully thinking about the consequences of
marijuana use Therefore interventions for those with externalizing
problems may be more peer-focused while interventions for those
with attentionconcentration problems may be more inwardly focused
on strategies for controlling impulsivity Given that the highest risk
period for these transitions is entry into high school strategies for
dealing with the increased academic and social demands of high school
is critical in these problem behavior subgroups in which academic
problems are co-occurring
Limitations of the study should be noted Reliance on self-reported
marijuana use could be subject to underreporting bias however this
study was designed to be sensitive to ethnic-minority populations
with the intent of maximizing participation and minimizing under-
reporting of drug-using behaviors The small number of non-
minorities in the original sample precluded our ability to make anymeaningful (or statistically stable) comparisons between minorities
and non-minorities A larger and more diverse sample may have
allowed not only for ethnic comparisons but identi1047297cation of more
subgroups
Limitations in our sample size may have also hindered our ability to
detect group differences as evidence by a limited number of statistically
signi1047297cant 1047297ndings in the LTA modeling A focus of future work which
we did not consider should be other factors known to be associated
with substance use such as family peer and neighborhood factors
and how they might modify the in1047298uence of academic and problem be-
havior subtypes on transitions in marijuana use in a low-income ethnic
minority population We also caution the reader that the current study
maynot be generalizable to non-urban settings in which early academic

and behavioral pro1047297les school readiness and access to and norms
around marijuana use may differ
Despite these limitations the greatest strength of this study is the
availability of a large sampleof African-Americans participatingin a lon-
gitudinal study designed to be sensitive to ethnic-minority populations
with annualdata collection Prospective studies like this onemdash featuring
a representative cohort of an entire entering class of 1047297rst graders are
relatively rareparticularly bridging the development periods from mid-
dle school to high school Even rarer are prospective studies of African-American youth from neighborhoods that are characterized by high
levels of community violence crime and poverty An understanding
of the ldquosurvivorsrdquo in such an environment canpotentially greatly inform
the next stage of preventive intervention efforts While a larger and
more diverse sample may have allowed the identi1047297cation of more
subgroups cohort differences and ethnic comparisons a community
cohorthas thebene1047297t of identifying within-group differencesin a highly
vulnerable and under-investigated population not always fully cap-
tured in national surveys Our ability to more accurately re1047298ect the
true nature of African-American drug use is what makes this a unique
contribution to the literature
In summary our 1047297ndings highlight the importance of developing
prevention programs and providing school services that address the
co-occurrence of academic and behavior problems as well as their
subtype speci1047297c risks for marijuana involvement particularly for low-
income urban-dwelling African-American youth who may be entering
school less ready than their non-minoritypeers These1047297ndingsalso pro-
vide evidence for a need to continue to deliver interventions in middle
school andhigh school focused on factors that mayprotect youth during
these critical transition periodswhen they may be especially vulnerable
to opportunities to use marijuana based on their academic and behav-
ioral risk pro1047297les
