Objective: We analysed more than 40 studies. A total of about 1500 persons were treated in all the studies combined. In most of the studies ( greater than 20) the treated persons were homo/bisexual men. The mean age is 35. The mean, since time of diagnosis, was 28 months. The average amount of sessions was 13. The control of medication was carried out only in some studies. Classification of the studies to the types of intervention: 1. Cognitive behavioral, 2. Stress-inoculation trainings, 3. Hypnotherapy/ Relaxation, 4. Humanistic (e.g. Rogers), 5. Sports, 6. Aerobic. Method: We calculated effects sizes separately for intervention and control groups and tested later for differences between the groups. Results: There is an over all superiority of the cognitive behavioral interventions in the domains of anxiety, depression, partly in symptoms. The humanistic forms were better for quality of life. Relaxation when systematically used, leads to a decrease of anxiety (r=-.27) in comparison with other interventions which do not use relaxation (r=. 17), (p is less than .10). Concerning improvement of psychological and physical symptoms, interventions which systematically used relaxation were more sucessfull (r=-.20) than interventions without relaxation r=-.11), (p is less than .06). Conclusion: Interventions using techniques like relaxation, cognitive changing strategies, inner communication were more successful in reducing anxiety (r=-.26) than other interventions (r=-.13), (p is less than .005). Differences in reducing depression were also statistically significant. Interventions using this type of technique showed a reduction (r=-.29), without these techniques (r=-.15), (p is less than .05).
