The aim of this paper is to describe the development of a questionnaire, the Dysmorphic Concern Questionnaire (DCQ), for the assessment of dysmorphic concern, and to establish correlations with clinical variables.
Consecutive admissions to a psychiatric hospital were surveyed.
The DCQ showed good internal consistency, with most of the variance being explained by a single factor. Strong correlations with distress and work and social impairment lend face validity to the questionnaire. Dysmorphic concern was not significantly influenced by the patient's age, sex or diagnosis. In terms of specific psychotic symptoms, there were weak positive correlations with thought interference and persecutory ideation. However, the strongest correlations were with depressed mood, according to the Beck Depression Inventory (BDI) but not the Montgomery Asberg Depression Rating Scale; the discrepancy was largely accounted for by the 'cognitive' depressive items on the BDI. In terms of objective assessment of dysmorphic features, ratings on the Waldrop scale for minor physical anomalies showed no correlation with concern expressed by the patient.
The strong correlation with depressive cognitions suggests that dysmorphic concern is often a reflection of a depressive cognitive set rather than being a diagnosis in itself.
本文旨在描述一份用于评估畸形担忧的问卷——畸形担忧问卷(DCQ)的编制过程,并建立其与临床变量的相关性。
对一家精神病医院的连续入院患者进行调查。
DCQ显示出良好的内部一致性,大部分方差由单一因素解释。与痛苦以及工作和社会功能损害的强相关性赋予了该问卷表面效度。畸形担忧并未受到患者年龄、性别或诊断的显著影响。就特定的精神病性症状而言,与思维干扰和被害妄想存在微弱的正相关。然而,根据贝克抑郁量表(BDI)而非蒙哥马利-艾森伯格抑郁评定量表,最强的相关性是与抑郁情绪;这种差异在很大程度上是由BDI上的“认知”抑郁项目造成的。就畸形特征的客观评估而言,Waldrop轻微身体异常量表的评分与患者表达的担忧无相关性。
与抑郁认知的强相关性表明,畸形担忧往往是抑郁认知倾向的一种反映,而非其本身就是一种诊断。
