This guide is intended to familiarize therapists with the scope of marital difficulties and the range of techniques found useful in dealing with them. While it is tempting to think that proven techniques can be matched to specific marital problems, the literature cautions that predicting outcome in therapy research depends not only on the technique used, but also on therapist and couple characteristics, choice of conjoint, individual, or group therapy, as well as other variables of the therapeutic setting. Results of empirical investigations of these factors are inconclusive. Therapists can, however, examine results of empirical outcome research to distinguish which techniques are most helpful for certain problem areas. The 26 problems, presented alphabetically, include Alcoholism, Behavior Deficits and Excesses, Communication Breakdown, Hostility, Money and Sex. Sources used are representative of current outcome research and case presentations attesting to the effectiveness of the techniques described under each problem heading. For each problem area, one or more techniques are suggested as useful to therapists during treatment of couples. (Author)
