Most studies of the Olson Circumplex Model of Marital and Family Systems have utilized a version of the Family Adaptability and Cohesion Evaluation Scales (FACES). Because FACES does not appear to operationalize the curvilinear dimension of the Circumplex Model, researchers have been pessimistic about the model's validity. However, the Clinical Rating Scale (CRS) has received some support as a curvilinear measure of the Circumplex Model. Therefore, we used the CRS rather than FACES to test the validity of the Circumplex Model hypotheses. Using a structural equation-modeling analytical approach, we found support for the hypotheses pertaining to the effects of cohesion and communication on family functioning. However, we found no support for the hypotheses pertaining to the concept of adaptability. We discuss these results in the context of previous studies of the Circumplex Model using FACES. Based on the collective findings, we propose a preliminary reformulation of the Circumplex Model.
