In this interesting though controversial paper, the author describes a case of a twenty-year-old male transsexual who was given training in feminine behavior prior to sex-change surgery. The approach was a modification of a social skills training program and utilized coaching, modeling, video-feedback, and behavior rehearsal. There was also concurrent psychotherapy with a psychiatrist. Ten raters judged the subject's behavior as significantly more appropriate and more effectively feminine after treatment than before. Results of psychometric testing were more equivocal. The patient reported better adaptation and greater social ease. The author concluded that behavioral intervention before surgery can help a male transsexual with the acquisition of feminine skills and identity.
