Validation of the Body Dysmorphic Disorder Questionnaire in a community sample of Swedish women.
Body Dysmorphic Disorder (BDD) is characterized by a distressing and impairing preoccupation with a nonexistent or slight defect in appearance. Patients with the disorder present to both psychiatric and non-psychiatric physicians. A few studies have assessed BDD prevalence in the general population and have shown that the disorder is relatively common. To date, no BDD assessment instruments have been validated in the general population. Our aim was to validate a brief self-screening instrument, the Body Dysmorphic Disorder Questionnaire (BDDQ), in a female community sample. The BDDQ was translated into Swedish and filled out by 2891 women from a randomly selected community sample. The questionnaire was validated in a subsample of 88 women, using the Structured Clinical Interview for DSM-IV (SCID) together with clinical assessment as the gold standard. In the validation subsample, the BDDQ showed good concurrent validity, with a sensitivity of 94%, a specificity of 90% and a likelihood ratio of 9.4. The questionnaire can therefore be of value when screening for BDD in female populations.
