Background and purpose: Since there is no test to evaluate body dysmorphic metacognition, the purpose of this study is to construct and determine the validity, reliability, and the factor structure of Body Dysmorphic Metacognition Questionnaire (BDMÇQ). Materials and methods: Data were collected through Body Dysmorphic Metacognition Questionnaire which was filled out by 200 students (100 male and 100 female), 20 patients with body dysmorphic disorder (BDD) and 20 students without BDD. Results: Çoncurrent validity of BDMÇQ with Yale –Brown Ôbsessive Çompulsive Scale modified for BDD was r=0.74 (P<0.001). Ïn an exploratory factor analysis, four factors were identified and labeled as follows: metacognition control strategies, thought –action fusion, positive and negative metacognitive beliefs about appearance, and safety–seeking behaviors that explained 48 % of the questionnaire variance. Ïn addition, scores of the group with BDD were significantly higher than that of the healthy group showing good diagnostic validity of the questionnaire. The Çronbach's alpha for the four factors was above 0.70. Çonclusion: Âccording to the results, BDMÇQ has a good reliability and validity to assess the metacognition problems in patients with BDD.
