Abstract
Behavioral Marital Therapy has focussed on the modification of marital behavior in conjoint and couples group settings. This study extends previously published outcome studies in that one treatment condition involved treating only one of the partners. Fifty-seven couples were consecutively assigned to one of the three treatment conditions. Outcome evaluations included an independent assessment, marital satisfaction, sexual adjustment and an assessment of target problems. The results revealed no significant differences between the three treatment conditions. However, couples in the conjoint treatment resolved their target problems more rapidly than the other two treatments. The implications of the result as well as issues of outcome prediction, cost-effectiveness and the viability of treating one spouse are discussed.
