The subjects had all been arrested and convicted of sexual offenses or had been engaging in illegal behavior including pedophilia, exhibitionism, voyeurism, or obscene telephone calls. Each of the subjects had been referred for evaluation for pharmacotherapy because of a lack of response to psychological treatment, intense and recurrent obsessions, difficulty in controlling their paraphiliac urges, and unremitting symptoms of anxiety and depression. The participants were administered the Hamilton Anxiety and Depression Scales, the Beck Depression Inventory, and the Yale-Brown Obsessive-Compulsive Scale and responded to semistructured interviews. The patients reported that they found serotonergic medications to be effective in reducing anxiety and depression, decreasing paraphiliac obsessions, increasing control over compulsive sexual behavior, reducing nonsexual obsessive-compulsive behaviors, improving concentration and other cognitive processes, and increasing ability to engage in psychotherapy. 2 tables and 20 references
