The Circumplex Model focuses on the three central dimensions of marital and
family systems: cohesion, flexibility and communication. The major hypothe
sis of the Circumplex Model is that balanced couple and family systems tend
to be more functional compared to unbalanced systems. In over 250 studies
using the Family Adaptability and Cohesion Scales (FACES), a linear self-re
port measure, strong support has been found for this hypothesis. In several
studies using the Clinical Rating Scale (CRS), a curvilinear observational
measure, the hypothesis was also supported. These two assessment tools, th
e FACES and the CRS, are designed for research, clinical assessment and tre
atment planning with couples and families.
