Convergent and discriminant validity of FACES-III: family adaptability and cohesion.
Research on earlier versions of the Family Adaptability and Cohesion Evaluation Scales (FACES) has ostensibly shown that the scales lack discriminant and convergent validity (23). However, these studies have defined convergence as agreement between family members or as agreement between family members and family therapists. Such definitions confound real differences between respondents' perceptions of the family with the notion of convergent validity. In the current study, we take a different approach to construct validity. Multiple measures of family adaptability, cohesion, and talkativeness were administered to two family members (insiders) and two significant others (outsiders). The two insiders' responses were averaged together, as were the two outsiders' responses. Using confirmatory factor analysis, we demonstrated that family adaptability, cohesion, and talkativeness are distinct traits, and that the different sources of information about these traits, including FACES-III (24), have convergent validity.
