“…Treatments derived from cognitive positions have been aimed at depressive thought processes (e.g., Beck, Rush, Shaw, & Emery, 1979;Fuchs & Rehm, 1977), whereas those derived from behavioral positions have been aimed at the improvement of social skills (Hersen, Bellack, & Himmelhoch, 1980;Sanchez, Lewinsohn, & Larson, 1980;Zeiss, 1977), at increasing pleasant activities and time management relaxation skills (Lewinsohn, 1977), and at more general problemsolving skills (McLean & Hakstian, 1979). In spite of this diversity, empirical support for the therapeutic efficacy of each has been provided (for recent reviews see Hollon & Beck, 1978;Lewinsohn & Hoberman, 1982;Parloff, Wolfe, Hadley, & Waskow, 1978;Rehm, 1981;Rehm & Kornblith, 1979). The problem facing the practitioner at this point is one of choosing from among a range of promising conceptual formulations and therapeutic approaches.…”
