A COMPARISON OF THE McMASTER AND CIRCUMPLEX FAMILY ASSESSMENT INSTRUMENTS*

This study compared clinical rating scales and self-report scales from the McMaster and Circumplex models of family functioning. Forty-one families were given self-report measures, while clinicians assessed the families using clinical rating scales. There are three main findings: (a) The McMaster instruments have superior sensitivity (i.e., ability to correctly identify clinical families based on instrument scores); (b) there is greater correspondence between clinical rating scales and family member self-report inventories on the McMaster instruments; (c) there is lack of support for the curvilinear model of pathology suggested by the Circumplex model, as evidenced by unequal and linear distribution of scores on the Circumplex dimensions.
