摘要

Background and Objectives: Recent studies explored the relationships between metacognitive beliefs and body dysmorphic disorder. The purpose of this study was to develop and validate one self-report scale of metacognitive factor about body dysmorphic. Methods: Development of this scale involved three steps: 1) items generated from a qualitative study with lecture and care professionals, 2) expert panel review, and 3) pilot test.

Results: Study showed that scores on the 25-item measure correlated with five theoretically related constructs, including positive and negative metacognitive beliefs about body dysmorphic, thought-fusion and metacognitive control strategies. Convergent validity of Body Dysmorphic Metacognitive Scale (BDMCS) with Yale-Brown Obsessive Compulsive Scale was modified for Body Dysmorphic Disorder (BDD) and Thought Fusion Instrument (r = 0.44, r = 0.52, P
