4 AREAS FOR TODAY• NEW FEATURE OF THE VINELAND II• CHANGES IN THE PURPOSES OF
ADAPTIVE BEHAVIOR ASSESSMENTS
• RECENT RESEARCH ON EFFECTS OF INTERVENTION WITH PERSONS WTH HIGH FUNCTIONING ASD
• CLINICAL APPLICATIONS AND ADAPTIVE PROFILES
Adaptive Behavior Assessment
Working our way back:
30 years since Pl 94-142 (1975)
16 years earlier AAMD (1959)
24 years earlier Edgar Doll published
The Vineland Social Maturity Scale (1935)
Things Have Changed
More and more assessing adaptive behavior has had broader applications
One reason is that different research has demonstrated that there appear to be
different profiles for various diagnostic groups
USES OF ADAPTIVE BEHAVIOR ASSESSMENTS
– Confirming or establishing diagnosis– Special services qualification– Program planning– Progress reporting/tracking– Identifying changes over time
USES, conintued
– Mental Retardation– Early Childhood Special Education– Autism Spectrum Disorders– Traumatic Brain Injury– Adult Mental Problems– As a measure to support the diagnosis of other
disabilities– Death Penalty Cases and
– Many others
A word about Death penalty cases:
Atkins versus Virginia.
Psychologists will be increasingly asked to provide testimony in these cases, mainly regarding adaptive functioning
A Virginia court just ruled that Atkins did not meet criteria for a diagnosis of mental retardation
2005
Supreme Court rules that individuals with (chronological) age under 18 years cannot be executed.
What about mental age?
VINELAND-II Overview
• Because clinicians have different needs when it comes to assessing adaptive behavior, we now offer four forms:
--Survey Interview Form– NEW Parent/Caregiver Rating Form– Teacher Rating Form– Expanded Interview Form
MAJOR NEW FEATURES• Ages: Birth to 90 years of age• New Norms• Increase Item density at floor and
ceiling• Extensive investigation and
elimination of item bias• Increase items relevant to ASD and
young children• Eliminate outdated items• Increase Items reflecting our
society’s technological advances• Subdomain standard scores• New Maladaptive
Other New Features
• Parent Caregiver Forms
• Teacher report Form – – Daily Living Skills
• Personal Subdomain• Academic Subdomain• School-Community Subdomain
• Attention Deficit/Hyperactivity Disorder• Autism – nonverbal• Autism – verbal• Learning Disability• Mental Retardation – Mild (child)• Mental Retardation – Moderate (child)• Mental Retardation – Mild (adult)• Mental Retardation – Moderate (adult)• Emotional Disturbance• Visual Impairment• Hearing Impairment
Validity Evidence: 11 Clinical Groups
• Vineland Adaptive Behavior Scales• Adaptive Behavior Assessment
System (ABAS)• WISC III• WAIS-III• BASC-2
Validity Evidence: Criterion
Internalizing Items• Is overly dependent • Avoids others and prefers to be alone • Has eating difficulties • Has sleep difficulties • Refuses to go to work or school because of
fear, feelings of rejection, or isolation • Is overly anxious or nervous • Cries or laughs too easily • Has poor eye contact • Is sad for no clear reason • Avoids social interaction • Lacks energy or interest in life
Externalizing Items
• Is impulsive• Has temper tantrums• Intentionally disobeys or defies those in
authority• Taunts, teases, or bullies• Is inconsiderate or insensitive of others• Lies, cheats, or steals• Is physically aggressive• Is stubborn or sullen• Says embarrassing things or asks embarrassing
questions in public• Behaves inappropriately at the urging of others

Maladaptive Behavior by Age for Individuals with MR
School-aged children with MR (all levels) had maladaptive means significantly higher than age matched clinical groups but < 1SD difference.
Adults (19-90) with MR (all levels) had maladaptive means significantly higher than age matched clinical groups AND school aged groups with MR
Maladaptive Behaviors by Age for Individuals with MR
Differences were greatest in the adult severe-profound group
Only Internalizing behaviors fell into the “elevated range” (the highest level) for this group
Adaptive Functioning of Mental Retardation Groups
For all levels and ages, mean levels of all domains and the adaptive behavior composite were at least 2SD below the mean

Mean age 11.8Mean IQ 54Vineland scores were so low we had to
use age equivalents/mental age ratiosThus, if Adaptive Behavior was

Asperger and high functioning autism
• Ami Klin
• Fred R. Volkmar

• Kathy Lord
• Domenic V. Cicchetti•All the participating families from the Yale Child Study Center and the Autism and Communication Disorders Center at the University of Michigan
• NICHD grant 5-PO1-HD03008
Special Thanks
• Autism symptoms have a severe impact on a person’s ability to meet the demands of everyday life
• Extreme variability in symptomatology and cognitive ability affects daily functioning
• “Higher-functioning” individuals, despite potential, fail to translate their skills to real-life adaptation
Recent Research in ASD
• Increasing focus on early diagnosis & intensive intervention = progress
• Still enormous variability in outcome– 12% achieving “very good outcome”
– 60% with “poor” or “very poor outcome” (Howlin, Goode, Hutton, & Rutter, 2004)
• Cognitive & language measures
• Does higher cognitive ability = greater outcome in adulthood???
• Translating potential into real-life skills becomes critical – Adaptive Behavior
Outcome in ASD
• “Real-life” Skills
• Vineland Adaptive Behavior Scales (Sparrow, Balla, & Cicchetti, 1984)
– Communication Daily Living Skills
– Socialization Motor
• Communication & Socialization skills = central & defining features
• Deficits in adaptive skills fall below cognitive ability across the spectrum– Significant deficits in socialization
– Intermediate deficits in communication(Bolte & Pustka, 2002; Carter et al., 1998)
Adaptive Functioning in Autism
• Consistent findings: – Adaptive impairments exist beyond MR– No entitlement for services without MR
• Inconsistent findings:(Freeman, Del’Homme, Guthrie, & Zhang, 1999; Liss et al., 2001; Schatz & Hamden-Allen, 1995; Szatmari, Bryson, Boyle, Streiner, & Duku, 2003)
– Positive relationship• e.g., Vineland Communication & VIQ• Early language and nonverbal IQ predicting
outcome for both comm. & socialization skills
– Negative relationship
Relationship between IQ and Adaptive Functioning
•Equally unclear relationship:
– Stable relationship
(e.g., Schatz & Hamden-Allen, 1995)
– Increase in AF w/ age
(e.g. Freeman et al., 1999)
– Decrease in AF w/ age
(e.g. Szatmari et al., 2003)
Relationship between Age and Adaptive Functioning
• Varying measures to assess severity of autism symptoms–Autism Behavior Checklist
–Childhood Autism Rating Scale
–Autism Diagnostic Observation Schedule
• Other factors (e.g., adaptive behavior and language) appear to be stronger predictors of outcome than severity of symptoms
• Very little research on relationship between symptomatology and adaptive behavior
Autism Symptomatology
• Cognitive potential may or may not play a role in positive outcomes
• Severity of autism symptoms may or may not play a role in positive outcomes
• Early detection and intensive intervention are beneficial to some, but not all, individuals on the spectrum
• “Real-life” skills are important for outcome– adaptive communication & social skills
Many Unanswered Questions
• Examines relationship between adaptive behavior (ability) and severity of symptoms (disability)– Vineland Adaptive Behavior Scales
– Autism Diagnostic Observation Schedule
• Investigates nature of ability & disability in relation to:
– Age
– IQ
– Diagnostic Classification
Present Study

judgment of 2 licensed clinicians • Verbal IQ > 70• Age range from 7 to 18 years

Real-life (adaptive functioning) in higher functioning individuals with autism and
PDDs
• Social ability and disability: two relatively dissociated domains (correlation)!!!!!!!
• Social disability is not correlated with age (stable)• Social ability is negatively correlated with age (decline
relative to peers, relative to increasing demands of the environment)
• Most programs emphasize reduction of symptoms
• Conclusion: all programs should prioritize adaptive functioning (REAL-LIFE SKILLS)

ConclusionsAssessment of Adaptive functioning is important
for individuals within any diagnostic categoryDetermining how everyday life (adaptive
functioning) is affected by nature or nurture (or both) should be our goal
Research and clinical work has shown us how different profiles are found in different groups
Aside:(Program planning and assessment of change after intervention are other goals of adaptive behavior assessment)
