Determine the effectiveness of metacognitive training on anxiety, body image and symptoms in patients with body dysmorphic disorder (BDD)

The purpose of this study was to determine the effectiveness of metacognitive intervention[MCI] on anxiety, body image and symptoms of BDD. The design of this study was clinical trail with control group. Using volunteers from referral to dermatology and cosmic surgery clinics, 30 participants were selected and were randomly assigned to the experimental and control groups. The Yale-Brown Obsessive Compulsive Scale Modified for Body Dysmorphic Disorder [BDD-YBOCS], Fisher body test and Beck Anxiety inventory [BAI] were used as the pre and post-test measures. The intervention group received 8 weekly metacognitive intervention sessions. The control group was in the waiting list until the post-test. The analysis of covariance showed the MCI had a significant effect on controlling the symptoms of BDD, anxiety and body image. All patients in intervention group showed improvement on self-report measures at post-treatment. So, the metacognitive treatment appears promising in body dysmprphic patients.
