Sidney Jourard's (19) description of the role of self-disclosure in marriage is reviewed. George Kelly's (20) theory of personal constructs is described in an effort to explain the complexity of successful marriages and strong families. A kind of marital therapy based on the technique of self-disclosure and the rationale that couple pathology results from erroneous personal constructs is described. The idea that these faulty schemas largely derive from the observation of and experience with one's parents' marriage is discussed. The self-disclosure of personal constructs may provide a distinctive approach to family therapy.
