This paper reuietus the l iterature abou,t Olson's Circumplex model,and attempts to resolue two problems that haue been discouered byattempts to use the modeL. The tu;o probLems are that: tI i themodel theorizes that the relationships in it are crrt: i l inear, butsome data and some other theorizing suggest that at Least one ofthe relationships is l inear; and 12) the role of'communication in themodel is problematic. This paper proposes that the solution to thecontrouersy obotLt the shape of the relationships is that therelationships probably haue a different shape than preuiousLl,thought.

Olson's Circumplex model is one of rhe most valuable middle-rangetheories in coniemporary family science. It is oniy a decade oid tOlson,

As with most theories. there are unresolved problems rvrth Olson's

circumplex model, and there are ways it can be improved. This paper is an

attempl to review the l iterature about the model. clarif l ' severrl of the

controversies and limirations of the theory, and make several suggestions

which we hope wil l improve the modei and stimulate additional rheoretical,

conceptual, and empirical work. Hopefuliy, lhe suggestions also wii l make the

modei more useful to practit ioners such as therapists, famrly i i fe educators,

extension speciaiiscs, and famiiy scientists using it in business. induscry and

government.

THE CONTROVERSY ABOUT THE SHAPE OF RELATIONSHIPS

One of the controversies the model has stimulated is that chere are

different opinions about the shape of the relationships in the theory' Olson

( 1976) has proposed thar adaptabil ity and cohesion are related to family

effectiveness with symmetrical and curvil inear relationships. He views rhe

independent variables as having four categories as shown in Figure l, and

theorizes that famiiies in the balanced area have the grealest probabil ity of

being effective. Families in the extreme condil ions are thought to have

higher probabil it ies of ineffecciveness.

The controversy deals with rhe relationships that adaptabil ity and

cohesion have with famiiy effectiveness. The data from some studies -cuggestthese reiationshrps are curvri inear. but other srudies have found relativell '

I inear relationships. Aiso. some theorizing about the effects of adaptabil ity

suggests it has a curvil inear relationship, but other lheorizing suggests It IS a

Iinear relacionship.

Empirical Reosons For the Controuersy

The largest and most careful study of the relationships in the model wasOlson and McCubbin 's survey of 1.000 fami l ies (Olson. NlcCubbin, et a l . , 1983).The main findings from their study are reproduced in Table l. and therelabionships are all positive. None of the covariation is negative r.t enypoint along the range of variation in adaptabil ity or cohesion. It is clearfrom the data in Table 1 that lhe relationships are not i inear. If therelationships were l inear, it would mean that the scores on rhe dependentvariables would increase equally as the scores on adaptabil ity and cohesionincrease from one category to another. From data in Table l. i t appears that,there is a slightly curved rather than linear relarionship. The changes inadaptabil ity and cohesion xre associated with greater differences in thedependent variables when the independent variables are in the lower end oftheir range of varia[ion than when they are in rhe higher end of their range.The mosf accurate way to describe these relafionships is that, they arepositive and slighrly curvil inear.

Barnes and Olson (1985) did a follow-up study that analyzed a sub-sample of Olson and NlcCubbin's (1983) survey of 1000 families. and theirstudy had conflicting findings. The data for rhe parents fit Olson's model ofcurvil inearity. but the data for the adolescents had a positive relationship.The discriminant analysis in rhe study also argued for positive reiarionshipsbetween adaprabil ity, cohesion" family satisfaction, and the quality of theircommunication.

November, 1987 FA}IILY SCIENCE REVIEW

One other study has data that allows strong inferences about the shape

of the rdailonsdps )n the modd. Ib )s Russd)'s (1979) dara on 3) "lorma)"

families. This study supports the curvii inearity suggested b-v Olson as it

found that families who had baianced scores on adaptabil it l ' and r'ohesion

were having less diff icuity with their adoiescent child and those rvho had

more extreme scores were having more difficuity.

A number of studies have compared pathologtcal or clintcai s'oups rvrth

more normal groups and found the ineffective groups had hrgher proportions

with extreme scores (Craddock. 19831 Garbar ino e! a i . . l9r{ : Clark. -96{: end

Rodick et e l . , 1986, for example). A few studies have iound no, j t f ferences

between cl in ical and normai groups (Alexander et . r1. . l r ; - l . , l r .nconciuslve

patterns (Sprenkle & Olson, 1978).

Some of the studies that have compared pathological rnd nornei ::oupsprovide useful information about measurement, clinicel. and predtction issues.

but these studies are of i i tt le value in helping us understand :he rnsp€ 'ri the

relationships in the theory. They have two problems that prevent :hem irom

being useful in making inferences about the relacionships. The tlrst :s :hat

the studies combine all four of Olson's ex[reme types into one group. end thrs

makes it impossible to make inferences about the relattonships eciaot.rbil i ty

-rnd cohesion have with effectiveness.

The second problem is that comparing ciinical and non-ciinrcei samples

to see differences in rhe proportions who have balanced and extreme scores

does not provide information about how variation in the independent venables

is associated with changes in the probabil ity of effectiveness. The irnding

that clinical and non-clinical samples differ in the proponion '*'ho are

balanced and extreme can appear if the relationships are posttive. end it can

appear if rhe relationships are curvil inear. For example. r,r 'hen e large number

of the ineffective families are in any one of the four extreme categories,

which is f requent ly rhe case (Rodick et .a i . , 1986, for example' i t rs impossrbie

lo know whal the relationships are when either or boch of che rndependent

variables vary.

The above sludies all have quantitative data, and the evidence irom them

seems !o be contradictory. There is also a sizeable bodl' of clinrcal i i terature(see Olson el a l . , f979, pp. 7-9) that uses qual i tat ive data. end these' lata are

more consistent in arguing for the curvil inearity proposed in the ctrcumpiex

model. These studies suggest that families who have unusurliv lorv or hrgh

adaptabil ity or cohesion |end to have higher probabil itres ,rf ,Iff icuit, '-. E,. 'en

though these clinicaliy derived observations have not been letecteci in rnost of

the quantitative research. this cype of daba is as important as rhe quantltatlve

data in building and improving theories, and these clintcai inferences need ro

be given serious cOnsideration in any attempt [o resolve the controversv.

The conciusion we draw from lhese studies is that tne emDlrlcal er-tcience

currenbly available is controversiai and contradictory. We think that lt may

be possible to resolve [he controversy, bur before suggestlng a resoiutron. the

theoreticai reasons for the issue should be identif ied.

Theoretical Reasons for the Controuersy About the Shape of the Relationships

Olson (1976) used the perspective and insights provided b;z sysremstheory in developing and then refining and expanding his modei (Olson er al.,1979; Olson et a l . , 19831 Olson, 1986). He rvas especial iy " inf luenced bygeneral systems theory as described by Von Bertalanffy (1968) and applied tothe fami ly by Jackson (1965), Haley (1962, 1963, 1964), Speer r1970). Hi l l(1971), and Wertheim (1973, 1975)" (Olson e[ a i . , .1983 p.71). His explanar ions(1983, p. 7O-72, for example) of rhe reasons the extremes of adaptabi l i ry andcohesion creale probiems in femilies provides ir. sJ*stems oriented rarionale thatis very convincing.

Beavers (1977, f981. f982; Beavers & Voel ler . 1983), on rhe other hand,has suggested a more psychodynamic and developmentallv oriented model rhatis quite different from Olson's. There are several importanr differencesbecween the Beavers and Olson models, but if t irese more complicated aspectsare ignored and the differences are boiled dorvn to the relationships. Beeversproposes rhat the relationship between adaptabil it-"- and effectiveness is i inear.He argues lhal "adaptabil iry as a confinuum is common |o rhe work of mostfamily clinicians and research workers. Whether one is speaking ofindividuals or families, highly adaptive means capable, and rnoderareadaptiveness is deflrned as not so good" t 1983:87).

A third theoretical approach was taken by Vincent q 1966) in afunctionally oriented sociologica.l anirrysis. He theorized thar the relarionshipbelween adaptabii ity and famiiy eff ,ctiveness is curvil inear. He proposed rhat"an industrialized society character'zed by rapid social change necessirates ahighly adaptive family svstem" t 966:36), but when the adaptabil iry isexcessive it is dysfunctional. "An e<ampie or i l lustration which curs acrossclass l ines is to be found in the internal adaptiveness of the family to irsteen-age members. When familial adaptation to the needs and wancs of irsteen-age members reaches the point or degree rvhere parental controi is lost,such degree of adaptat ion becomes dysfunccional . . . " (1966:36).

Thus, previous theoretical formulations seem to add to the controversyrather rhan heip. There are theoretical models from clinical impressions,systems analysis. and sociological analyses that argue for l inearitv andcurvil inearity, and the plausibil i ty of each of them needs to be taken intoaccounc.

A Proposed Resolution of the Controuersy

The conlroversy about the shape of the relationships can be resolved iftwo changes are made. First. we need to reaiize that the differences betrveenthe Beavers and Olson models is a conceptuai difference rather rhan adifference of opinion about the shape of one relationship. Beavers definesadaptabil ity "as an emerging, ever eKpansible capabii iry to be placeci on acont inuum ranging from dysfuncr ional to opt imal" {1983:89). This means tharadaptabil ity is defined as capabil ity or adaptive capacity. and this ciearly hasa qualirative or good-bad qurrl ity to it. We agree with him rhat rvhen

Adaptability Cohesion

adaptabil ity is defined in this way it has to have a positive relatronshrp *rrh

additive manner. This means that the distance from the mean in eitherdirection in both distributions can be added together and the greater rhetotal distance from lhe mean Lhe greater the l ikelihood of ineffectiveness.

Viewing adaptabil ity and cohesion as continuous variables makes itpossible to take into account smaller intervais in the variation of rhese twovariables, and this provides the key that we think is needed to resolve thecontroversy. The reason we think this approach can resoive the controversyis because the reiationships are probably positive for mosl of the range ofvarialion in the independent variables, bur the direction changes in theexrreme upper end of the range of rheir variation.

Our resolut ion of the controversy is to suggesl thar rhe modes in lhedistribucions in Olson's model are not at the 5Oth percentile as implied b-"- thecurrenl modei and the research about the mociel. The mode in rherelationship between adaprabil ity end family effectiveness is probablv muchhigher. The eKitct locat ion of the mode can onl-y be determined wirhaddirional research that wil l allow these discriminations. bur ir may be ashigh as the 80th or 90th percentile of a random sample. We suspecr thar thisreiationship probably does not become strongly negacive unti l ebove rhe g5th

percentile in the con[emporary Western culture. Also, rve suspecr that rheIevels of adaptabil ity that are associated with the highesr probabil ity ofeffectiveness is not a large part of the total range of variarion inadaptabil ity. Therefore, our attempt to diagram this relationship in Fisure 3shows the mode to be fairly pointed. Also, we have included rhe slight curvedetected in Table 1 by dirrgramming a fairly strong relationship betweenadapcabil ity and effectiveness in the low end of its distribution.

Our interpretation of the data from previous research. and our clinicaland educationai impressions suggest thal the reiationship is probabiy somervhatdifferenl for cohesion and effectiveness. This relationship is drarvn in Figure3, and it also shows two directions in the relarionship. We suspec[ rhac rhemode is lower for cohesion than adaptabil ity, and we think rhar ir is a moreflat mode. If future data corroborate these theoretical speculations it meansthat having high cohesion is not as importanL for effectiveness as having highadaptabil ity. I l also means thar famiiies can choose among a much widerrange of cohesion and sti l l expect to effectively attain the outcomes or goalsrhey seek in their famiiy system.

These speculations seem to be an effective resolution of the differencesin the earlier theorizing and research. They allow for the curvii inearityproposed by Olson and Vincent, and they also recognize that the covaria[ionthat adaprabil ity and cohesion have with effectiveness is positive throughmost of lhe range of variation in the independent variables. The reason thechange in direction in the reiationship has not be detected rn the quantirativeresearch probabiy is because researchers have not used measures that aresensitive enough [o detect the negative covariation in the top part of thediscributions. The resolution also allows for the slight curvii ine:rrirv thatoccurs because changes in adaptabil ity and cohesion below their mid-pornthave a stronger relationship than above rt.

Conversely, it is l ikely that cuitures that are experiencing less change rvil lhave a more normal distribution in rhis relalionship. Also, it, is [kely thabthe mode for fhe relationship between cohesion and effectiveness is morepointed during periods of relative stabil ity, and during these periods the modefor adaptabil ity is probably more flat than the relationship we have proposed

in Figure 3.

A PROBLEII WITH THE ROLE OF CONIITUNICATION IN THE I,IODEL

A second problem with the circumplex model has to do with the role ofcommunication in the theory. Olson has stated that the theory has threemain factors: adaptabil ity, cohesion, and the quality of communication.Unfortunately, though, uhe practical resuit has been that it has become a twofactor model. Communication is ignored aimost ail of the time. Olson hassuggested that communication is different because it is a "facil i tating"var iable (Olson and NlcCubbin. 1983, p.+9), but rh is is not a helpfui way todifferentiate the roles of rhe three independent variables. From a s]'stemstheory perspective, the same thing can be said for adapcabil ity and cohesion.They are not outcomes or goals. Thev are transformalion processes or svs[emcharacteristics that help famiiies attain desired outcomes or goals such assatisfaction, affection. stress management, developmental tasks. consensus. andoptimai human growth.

It rvould be possible to make a case for cohesion being viewed sometimesas an outcome in familv systems because families sometimes talk about

Kindness is lhe amount famiiy members respond in a caring, loving,considerate and patient manner lo each other, especially when things arenot going weil in the family.

Consensu.s is the amount the famiiv tries to use a consensus-seeking method of making decisions. This method is somerimescalled a win-win method, and Gordon (1970) refers to it as hismethod III.

Control is how adequately the family is able to gradually transferto chi ldren the responsibi l i ty for valrous aspects of rheir own I ives.

Anger is a measure of how weil the famiiy is able to keep tempersand anger from being disruptive in the famiiy and horv rvell theyturn anger into construct ive uses. I t is adaprcd from ] Iace's i198 l )pornt of view of the role of anger in enrichment programs.

Support measures the amounc family members provide nurrurance toeach other through physical contact, helping each other achievesuccesses, and companionate interact ion. I t is used the way i t wasdefined in the Roll ins and Thomas review (1979), and includes thefactors derected in several recent factor analvses of suDDor[(Barber and Thomas. 1986).

The lines in Figures 5 and 6 show the data from [wo families thatparticipated in a PAT lVorkshop. These families were lwo of the moretroubled families that participated, and the data in these tables i l lustratesome of the benefits of using the profi le system ro help understand famijiesthat apply for enrichment programs.

Figure 5 shows the data for a family that we wil l cail the Smiths. TheSmibhs have a single mo[her and three children, and data were gathered fromthe mother and a 13 year old daughter. The solid l ine shows the morher'sperceptions, and the dotted l ine shows the daughter's. The mother perceivedthe family as being fairly good in most areas, but low in cohesion andlistening as these scores were belween 20 and 30. Some of the daughter'sscores were similar rc the mother's, but the daughter had much lower scoreson support and kindness. This information helped the workshop leadersrecognize that rhe daughter felt the family was not as effecrive as themother chought; and thab the daughter felt alienated and unappreciated. Thiskind of information helped the workshop leaders and participants find wa.v*schey could adapr the rvorkshop to help meef these specific needs. This famiil 'deliberately designed activit ies that would heip create interaction,understanding, and feelings of being included by the daughter.

Figure 6 shows the profi le of a famiiy that we wil l call the Jones. afamily that is quite differen[ from the Smiths. The Jones famiiy had twoparenls, one son, and four daughters. Figure 6 shows the scores for bothparents, the teenage son. and the teenage daughter. The scores show rhefather perceived the family to be fairly healthy, as he had no low scores.

TMPROVING A THIRD ASPECT oF THE CIRCUN{PLEX :vToDEL

There is another aspect of the circumplex model thar can be improvedby adding a profile method of summarizing data. The marn hypotheses in rhecircumplex model suggests that baranced families tend i" have higherprobabilities of effectiveness and extreme families have lower probabiiii ies(Olson et.al., 1983). Grouping several different rypes of families inro rhe"balanced" calegory is not a problem beceuse variarion in rhe middle part ofche range of variation with most variables has little value in famii-v- science.Predictive research since the lg30's has shown that the furrher people areout on the taiis of a distribution the grea[er the diagnosric. evaiuative, andpredictive power (Burgess and Cottrell, lgJg).

The limitation with fhe circumpiex model is rhat the rheorericai ideasthat have been generated and most, of [he research irbout the modei tend togroup all four forms of extreme conditions mgerher. when this is done ic

conceals variance that is potentially vaiuable. In this case, families with

certain combinations of extieme conditions may have different probabil it ies of

various types of ineffectiveness. For example, it may be that certain

combinations of the independent variables are associated rvith high

probabil it ies of undesirable outcomes such as violence. substence abuse' or

alienation, and other combinarions of extreme conditions are 3'ssociated rvith

other outcomes, such as deviance or inabil ity lo estabiish long-term

relat ionships. Rodick 's t1986) data. for example. suggest thet del inquenc\- mey

be more fiequent in chaoricaiiy enmeshed families rhan in en1' of the other

extreme types. Profi l ing these and oLher variables ma1- heip us uncierstand

horv other combinations of factors are associated rvith imput't 'r 'nI outcornes in

family systems.

The circumplex model distinguishes conceptuallv betrveen four :1-pes of

extreme conditions, but for some reason lhe theorizrng rnd rese:.rrch so flar

Fnds to ignore these distinctions. Theorists i lnd researchers :enci :o focus

on the diflerences between balanced and extreme l '3ther than iocuslng on

different types of extreme condirions. Ib is l ikel-"* thlt ecicitng 'r profi le

approach wil l make it easier to focus on ways the veriou: er'-reme conditions

ADVANTAGES, CAUTIONS AND FUTURE NEEDS

The two profiles in Figures 5 and 6 illustrate that prohles can ire very

helpful in a number of wayi in therapy and in enrichment Progr3tns. They

can help leaders know how to adapt or modify- programs u) me3 the needs

and goals of the participants. They also can help idenufy famrlies that

shouli be screened- out of enrichment programs because tbcy oced therapl"

and they can be used to monitor progress and evalual'e ihrl cfictiveness of

programs.

Profiles about family variables, such as the one begrg dacloped for the

PAT Workshop, also .utt b" valuable in a variety of oab hCily science

settings. For example, lhey could be used in family lift 1!fbo c'ourses'

Students beginning marriage and famill' classes could co6tb qElrnnaires

that would lead to profiles, and this could help rba !!, rmderstand

associated with changes in lhe probability of outcomes is a comfortable and

helpful way to rhink theoretically, empirically, clinically and educationally.

Profiles also focus attention simultaneousiy on several different

independent variables, and this helps schoiars avoid the overly simplistic two-

variable models that are so common. It also heips them identify

compensatory factors and the interaction of variables, and it is more

conducive to thinking in terms of strengths (Stinnett and Defrain. 1985) as

weil as problems.

When profi les are used, scholars also tend ro find themselves thinking

with stochastic or probabil istic models. They reason that changes in profi les

are associated with changes in the probabil ity of different ou[comes. This

type of reasoning is helpful in the contemporarv scene because it allows

precise thinking but avoids rhe host of problems that come with differences

of opinion about causation, de[erminism, free agency, and positivism thal are

concerns of some scholars (Osmond, 1981; Harre ' , Davide, and Nicola, 1985;

Thomas and Wilcox, 1987).

Profi les were first used in the famiiy field by Burgess and Wallin (1953),

but they have not been used extensively. There are a number of

psychological instruments Lhat provide profi le data about individual

characteristics, but we are only e',vare of [wo instruments that provide

profi les of family variables. The tv'o are Moos' (1983) family environment

scale and the Marital Inventory (MI tHolman et al., 1981). We sugges[ that,

for bhe reasons cited above, greabe. use of profi les would be very helpful to

the f-reld.

The development of effective, standardized instruments rhat profi le

family data wil l be a long-term process. It wil l involve a careful revierv of

theoretical models which can direct the process of selecting the variables t 'hal

should receive atlention, and it, will include the use of factor analy'sis to

determine redundance and orthogonalitv of factors. The instruments rvil l need

to be used enough to get norms and determine their reliabil i ty and validity,

and experience suggests they wrll need to be developed and then revised

before they will be very effective.

The next step is to engage in more of lhe systematic analysis of

concepts, theory, and measurement processes that' Ied Olson to identify

adaptabil ity and cohesion as two central variables in famiiy processes. This

analysis wil l help us identify a manageable group of other variables that wil l

provide complementary data. Next, the need wii l be to develop lnstrumenls

that effectively measure [hese factors, develop norms for them. :1nd acquire

evidence of reliabii i ty and validity. Fortunauely, the theory in the field and

rhe technology for instrument deveiopment are now sophisticated enough that

it is possible lo move ahead with this t.vpe of work at a rapid pace.
