Although marriage enrichment programs have been shown to be effective for many couples, a multidimensional approach to assessment is needed in investigating these groups. The components of information and social support in successful marriage enrichment programs were compared in a completely crossed 2 x 2 factorial design with repeated measures. Participants (N=72) were married couples assigned to one of four treatment groups: assessment only; unstructured, social support; information only; and structured group with information and support. Subjects completed the Dyadic Adjustment Scale, the Personal Assessment of Intimacy in Relationships, and the Primary Communication Inventory, and were videotaped discussing a problem. Videotapes were coded using the Marital Interaction Coding System. The results showed that couples participating in treatment groups improved their marriages relative to those who underwent assessment only. Most of the effect seemed to be in increasing marital satisfaction and positive verbal behavior in couples who interacted with other couples. The information about marriage enrichment provided in the programs seemed to have little measurable effect. (NRB)
