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.
体象障碍（BDD）的特征是一种令人痛苦和受损的关注，即对不存在或轻微的外表缺陷的关注。患有这种疾病的患者会向精神科和非精神科医生就诊。一些研究已经评估了普通人群中的 BDD 患病率，并表明该疾病相对常见。迄今为止，还没有在普通人群中验证 BDD 评估工具。我们的目的是在女性社区样本中验证一个简短的自我筛查工具，即体象障碍问卷（BDDQ）。BDDQ 被翻译成瑞典语，并由随机抽取的社区样本中的 2891 名女性填写。该问卷在 88 名女性的子样本中进行了验证，使用 DSM-IV 的结构化临床访谈（SCID）和临床评估作为金标准。在验证子样本中，BDDQ 显示出良好的同时效度，灵敏度为 94%，特异性为 90%，似然比为 9.4。因此，该问卷在女性人群中筛查 BDD 时可能具有价值。
