The literature contains few reports of behavior therapy used to treat compulsive gamblers. Desensitization (Draft, 1970),electrical aversion (Goorney, 1968; Seager, 1969),and a multifaceted approach including faradic shock, covert sensitization, massed practice, and time-out (Cotler, 1971)have been reported with mixed results. The increasing interest of behavior therapists in cognitive-symbolic mediation is well documented (Bandura, 1969; Mahoney, 1974; Meichenbaum, 1976);however, there are no reports of behavior therapists using a cognitive learning approach with a covert conditioning therapy to treat compulsive gambling. Such an approach is described in the present case report.
