259This study examines the efficacy of computer-assisted exposure (CAE) treatment in helping to overcome flight phobia and analyzes the role of relaxation and information-related components in the reduction of fear. Fifty flight phobics were randomly assigned to 1 of 3 methods of treatment: (a) CAE; (b) a multicomponent method of treatment of information, relaxation, and CAE (IRCAE); and (c) waiting list control treatment. At the end of the treatment, an actual flight was chartered. The results showed that the first 2 methods of treatments were more effective than the waiting list control treatment. The CAE group showed the greatest reduction in fear. According to data from the IRCAE group, no reduction in flight phobia was observed after the information-relaxation phase. Follow-up data showed that improvements in anxiety self-assessment rates remained constant.Despite the high clinical frequency of flight phobia and its personal and financial repercussions (Wilhelm & Roth, 1997; Van Gerwen, Spinhoven, Diekstra, & Van Dyck, 1997), well-structured treatment programs and controlled studies to evaluate the effects of such programs are scarce, especially when compared with other phobias, although systematic research on the topic has begun to increase.One method of reducing fear of flying that has been most commonly used over the last 30 years is a combination of relaxation techniques and the provision of aeronautical data. Despite its extensive use, the real effectiveness of relaxation training still remains unclear. In Howard, Murphy, and Clarke's (1983) controlled study, relaxation treatment was equally effective as systematic desensitization, flooding, and implosion. In contrast, Denholtz and Mann (1975) found systematic desensitization to flight pictures to be more effective than either relaxation alone or exposure to flight film without relaxation. Moreover, in several controlled trials using relaxation as part of cognitive-behavioral treatments (Beckham, Vrana, May, Gustafson, & Smith,
