Summary
Brief summary
This study tests whether Temgesic improves the effectiveness of exposure therapy for decreasing social anxiety symptoms. We predict that individuals from the community diagnosed with social phobia who receive four exposure therapy sessions in combination with Temgesic will experience a greater reduction in social anxiety symptoms in comparison to individuals who received the placebo in combination with four exposure therapy sessions. Participants receive, in total, five weekly group therapy sessions, the first is educational and the next four consist of public speaking exposure therapy. One month post intervention participants are assessed for social anxiety symptoms as well as other general health indicators. All subjects, therapists, assessors, and data entry staff are blind to condition.
