MedicalResearch.com Interview with: Dr. Jesper Enander Department of Clinical Neuroscience Karolinska Institutet MedicalResearch: What is the background for this study? Dr. Enander: Body dysmorphic disorder (BDD) is a common anxiety disorder affecting about 2% of the general population, and is associated with hospitalization, substance dependence and suicidality. The disorder is characterized by a intense preoccupation with perceived defects in physical appearance, despite looking perfectly normal. It is common for people with BDD to seek non-psychiatric care, such as dermatological treatment or plastic surgery, however, such treatments rarely work, and can even lead to a deterioration of symptoms. The National Institute for Health and Clinical Excellence (NICE) in the UK recommends that patients with Body dysmorphic disorder should be offered cognitive behavior therapy (CBT), however, there is a gap between supply and demand of CBT. One way of increasing access to CBT is to deliver it using the Internet. In this randomized clinical trial we tested the efficacy of a Internet based CBT program for Body dysmorphic disorder called BDD-NET and compared it to supportive therapy. MedicalResearch: What are the main findings? Dr. Enander: Our study shows that BDD-NET was associated with large and significant improvements in  Body dysmorphic disorder symptom severity. 56% of those receiving BDD-NET were responders (defined as at least a 30% reduction in symptoms), compared to 13% of those receiving supportive therapy. At the six months follow-up, 39% of those who received BDD-NET no longer met diagnostic criteria for Body dysmorphic disorder. No serious adverse events were reported, and most participants were satisfied with BDD-NET, despite no face-to-face contact with a therapist, and deemed the treatment as highly acceptable. (more…)
