Dimensionality of three family assessment instruments: FAM, FES, and FACES

Abstract

This research identifies the major dimensions exhibited across three self-report family assessment instruments: the FAM, FES and FACES. The instruments were administered to 138 families, consisting of a mother, father, and one child between 12-18 years old. Principal components analysis was used to identify dimensions across instruments. As dimensions were identified, correspondence across instruments was assessed. Results indicated that the instrument subscales could be organized along three factors, labeled Affect, Activities, and Control. Factor composition for different family members, although not identical, was highly similar. Results also indicated that there was relatively little correspondence across the three instruments. Lack of correspondence appeared to be largely caused by the limited dimensionality of the FACES and FAM. In contrast, the FES demonstrated greater range, contributing substantially to all three factors. Additionally, the obtained factors corresponded to the domains of the Family Environment Model: Relationships, Personal Growth, and System Maintenance.
