The current study addressed the concept of dysmorphic concern as a symptom that may exist in a number of disorders. The aims of the study were to: (i) validate a recently developed questionnaire that measures dysmorphic concern, the Dysmorphic Concern Questionnaire (DCQ); and (ii) evaluate the relationship of dysmorphic concern to depressed mood, social phobia, and obsessive-compulsive symptomatology.
Sixty-five psychiatric inpatients were diagnosed using the computerized version of the Composite International Diagnostic Interview (CIDI-A). They then completed the DCQ, and questionnaires measuring body dysmorphic disorder (the Body Dysmorphic Disorder Examination, or BDDE), depression, social phobia, and obsessive-compulsive disorder (OCD). The factor structure and convergent validity of the DCQ were determined, and associations with mood and anxiety symptoms explored.
The DCQ was found to be a reliable and valid instrument that is sensitive to dysmorphic concern. Furthermore, although dysmorphic concern was associated with body dysmorphic disorder (BDD), depression, social phobia and OCD, only the score from the BDDE predicted DCQ score in a multiple regression analysis. Finally, BDD symptomatology was best defined by the presence of negative body beliefs as measured by the DCQ.
Negative body beliefs are the hallmark of BDD. However, the existence of dysmorphic concern does not necessarily imply a diagnosis of BDD. The DCQ is a quick and efficient means of identifying dysmorphic concern in those who present with depression, OCD, social phobia or BDD.
本研究探讨了畸形担忧这一症状概念，其可能存在于多种疾病中。本研究的目的是：（i）验证最近开发的一种测量畸形担忧的问卷，即畸形担忧问卷（DCQ）；（ii）评估畸形担忧与抑郁情绪、社交恐惧症和强迫症状之间的关系。
使用综合国际诊断访谈（CIDI-A）的计算机化版本对65名精神科住院患者进行诊断。然后他们完成了DCQ，以及测量身体畸形障碍（身体畸形障碍检查表，或BDDE）、抑郁、社交恐惧症和强迫症（OCD）的问卷。确定了DCQ的因子结构和收敛效度，并探讨了其与情绪和焦虑症状的关联。
发现DCQ是一种可靠且有效的工具，对畸形担忧敏感。此外，虽然畸形担忧与身体畸形障碍（BDD）、抑郁、社交恐惧症和OCD有关，但在多元回归分析中只有BDDE的得分能预测DCQ得分。最后，BDD症状最好由DCQ测量的负面身体信念来定义。
负面身体信念是BDD的标志。然而，存在畸形担忧并不一定意味着诊断为BDD。DCQ是一种快速有效的方法，可用于识别那些患有抑郁症、OCD、社交恐惧症或BDD的人的畸形担忧。
