Although psychological and pharmacological treatment approaches for Body Dysmorphic Disorder have been evaluated, the relative effectiveness of these two types of interventions has not been examined. We conducted a meta-analysis of randomized clinical trials and case series studies involving psychological (i.e., behavioural, cognitive-behavioural, cognitive) or medication therapies. Our findings support the effectiveness of both types of therapy, but suggest that cognitive-behavioural treatment may be the most useful. These findings require cross-validation through large-scale clinical trials.
