Integrative family therapy is an integration of personality theory and counseling theory actualized in the counseling process. Personality theory contributes five interrelated concepts to a model of family therapy, including communication/perception, individual roles, family subunits, family themes, and individual personality dynamics; these concepts attempt to define the nature of individual and family function and dysfunction. In an integrative family therapy model, all therapist's interactions with the family are guided by the hypotheses generated from personality constructs. Research on the interaction of these concepts in dysfunctional families identifies a close correlation between several personality dynamics and family problems. The theory has been used with over 1100 families with relative success; however, further research is needed. (JAC)
