This paper reviews the major elements of the functional family therapy model, i.e., the conceptual underpinnings, empirical foundations, treatment goals, and technology. Topics addressed include: (1) the assumption that deviant behavior is an influence strategy not acceptable to others; (2) the use of intervention strategies; (3) the role of the family therapist; (4) the goal of therapy as attempting to change specific ways in which individuals interact in interpersonal functions; and (5) the use of assessment, therapy, and education in the model. The current status and future directions of the model are discussed in terms of long-term relationship analysis, expansion to include extra-familial relationships, and the service delivery process.
