Couples therapy using the technique of construct differentiation.

A central problem in couples therapy is the clients' tendency to persist in endless and fruitless alternation between attacking the partner and justifying themselves. The technique of construct differentiation described in this article has proved helpful in coping with this situation. In three clearly structured steps, the therapist explores the personal constructs of each partner in the presence of the other. Instead of concentrating in the usual way on circularity of thoughts, feelings, and behavior, the partners are hindered from interacting and are confronted by the therapist's questions concerning their own inner process, independently of that of the partner. By becoming aware of their own ambivalent constructs and those of the partner, the eagerness to convert the partner to their own point of view can be reduced, and the construct system of each partner can be enriched by the other's constructs. Construct differentiation proves especially useful in the treatment of power struggles and narcissistic collusions.
