A factor analysis of self-report measures of family functioning.

Four well-known, self-report measures of family functioning were serially examined in order to identify a limited set of reliable concepts for describing families. Following the completion of four separate data collection procedures, a 75-item scale comprising 15 dimensions of family functioning was constructed. The dimensions appear reasonably independent of each other and have satisfactory psychometric properties. An initial effort to validate the scales was undertaken by contrasting scale scores obtained from descriptions of intact families with those obtained from descriptions of families that subsequently were disrupted by separation and divorce. Significant differences in scale scores were obtained on 12 of the 15 dimensions of family functioning. The 15 dimensions of family functioning could be subsumed under the three general headings suggested by Moos, Insel, and Humphrey (14)--relationship dimensions, personal growth or value dimensions, and system maintenance dimensions.
