Facing social anxiety and avoidant personality disorder

Abstract

This dissertation compares the effectiveness of Group Cognitive Behavioural Therapy (GCBT) and Group Schema Therapy (GST) in treating patients with social anxiety disorder (SAD) and avoidant personality disorder (AVPD). AVPD is often comorbid in patients with SAD. Those affected suffer from avoidance, low self-esteem, and an intense fear of rejection. They experience difficulties in social situations, such as social conversations and attending school or work. Previous research has shown that Cognitive Behavioral Therapy (CBT) is effective in treating SAD. However, not everyone benefits sufficiently from it. This may be related to the severity of SAD and co-occurring, underlying personality traits. Schema Therapy (ST) has been developed for the treatment of personality disorders and chronic problems that do not respond sufficiently well to CBT. A comparison of GCBT and GST showed no significant differences in outcomes. Both treatments effectively reduced the symptoms of SAD and manifestations of AVPD. The characteristics of the examined clients did not predict whether they would benefit more from GCBT or GST. Nor was any evidence found for differences in underlying treatment processes. Therefore, patients can choose between the two treatments if both are available. However, GST has a lower dropout rate. Consequently, it appears to be the most effective treatment for SAD and AVPD.
