AIM To make such a comparison. METHOD A group of adults with high-functioning ASD (n=40) were administered the Yale-Brown(More)
Body dysmorphic disorder (BDD) is thought to be etiologically related to obsessive-compulsive disorder (OCD) but the available evidence is incomplete. The current study examined the genetic and environmental sources of covariance between body dysmorphic and obsessive-compulsive symptoms in a community sample of adult twins. A total of 2,148 female twins(More)
BACKGROUND The evidence base for the efficacy of cognitive behaviour therapy (CBT) for treating body dysmorphic disorder (BDD) is weak. AIMS To determine whether CBT is more effective than anxiety management (AM) in an outpatient setting. METHOD This was a single-blind stratified parallel-group randomised controlled trial. The primary endpoint was at 12(More)
Individuals with Body Dysmorphic Disorder (BDD) are preoccupied with perceived defects in their appearance that are not visible to others. An excessive focus and processing of details has been proposed as a possible mechanism underlying this distorted self-image in BDD. The nature and extent of visuoperceptual abnormalities in BDD however require further(More)
BACKGROUND AND OBJECTIVES Self-focused attention is hypothesized to be a maintenance factor in body dysmorphic disorder (BDD). The aim of this study was to use an experimental paradigm to test this hypothesis by studying the effect of self-focused attention during mirror-gazing on appearance dissatisfaction. METHODS An experimental group design was used,(More)
OBJECTIVE Body dysmorphic disorder (BDD) typically starts in adolescence, but evidence-based treatments are yet to be developed and formally evaluated in this age group. We designed an age-appropriate cognitive-behavioral therapy (CBT) protocol for adolescents with BDD and evaluated its acceptability and efficacy in a pilot randomized controlled trial. (More)
There is some evidence for the efficacy of cognitive behavior therapy (CBT) for body dysmorphic disorder (BDD) after 1 to 6months but none in the long term. The aim of this study was to follow up the participants in a randomized controlled trial of CBT versus anxiety management to determine whether or not the treatment gains were maintained over time.(More)
