“…This argument, along with clinical and anecdotal evidence, still forms the basis for competing claims of therapeutic efficacy. However, it seems likely that a less partisan approach has an increasing number of advocates (Garfield and Kurtz, 1976; Meichenbaum, 1977;Wachtel, 1977;Mahoney, 1980;Macfie, 1980;Phillips and Bierman, 1981).
