OBJECTIVE
The purpose of this study was to investigate the use of the Dysmorphic Concerns Questionnaire (DCQ) as a screening measure for body dysmorphic disorder (BDD) and to derive DCQ cutoff scores to facilitate the screening procedure.
METHOD
The DCQ was completed by 244 undergraduates (mean = 20.80, SD = 3.10 years) and 57 BDD outpatients (mean = 29.60, SD = 9.44 years) in Melbourne, Australia. The undergraduate sample was screened for eating disorders using the Eating Attitudes Test-26, and for BDD using the Body Dysmorphic Disorder Questionnaire.
RESULTS
The BDD outpatients obtained significantly higher scores on the DCQ than the undergraduates. This difference remained statistically significant after controlling for the severity of depression and social anxiety symptoms. A DCQ cutoff score of 9 resulted in the correct classification of 96.4% of BDD patients and 90.6% of undergraduates.
CONCLUSIONS
The results supported the use of the DCQ as a brief, sensitive, and specific screening instrument for BDD.
目的
本研究旨在探讨使用畸形关注问卷（DCQ）作为躯体变形障碍（BDD）的筛查手段，并得出 DCQ 的截断分数以促进筛查程序。
方法
澳大利亚墨尔本的 244 名本科生（平均=20.80，SD=3.10 岁）和 57 名 BDD 门诊患者（平均=29.60，SD=9.44 岁）完成了 DCQ。本科生样本使用饮食态度测试-26 进行进食障碍筛查，使用躯体变形障碍问卷进行 BDD 筛查。
结果
BDD 门诊患者在 DCQ 上的得分明显高于本科生。在控制抑郁和社交焦虑症状严重程度后，这一差异仍然具有统计学意义。DCQ 截断分数为 9 时，正确分类了 96.4%的 BDD 患者和 90.6%的本科生。
结论
结果支持使用 DCQ 作为 BDD 的一种简短、敏感和特异的筛查工具。
