This paper presents a methodology for using the Benjamin Structural Analysis of Social Behavior (SASB) model in individual, couple and family therapy to describe relations among self-concept, early history and adult relationships. The SASB model of two-person social interactions defines behavioral opposites, complements, antidotes and introjections. The model describes dyadic social interactions in terms of focus, affiliation, interdependence and topic. Topics include: primitive basics; approach-avoidance; need fulfillment, contact, nurturance; attachment; logic and communication; attention to self development; balance in relationship; intimacy-distance; and identity. The model has been confirmed by factor analysis, circumplex analysis, dimensional ratings and autocorrelations. Details of questionnaires, computer programs used to analyze data and interpretation of output are offered for both the clinician and the researcher. (Author/SE)
