Abstract

ABSTRACT Objective Body dysmorphic disorder (BDD) is a chronic mental health condition with symptoms typically emerging in early adolescence. Despite the onset in adolescence, most self-report BDD severity measures have not been validated with adolescent and young adult samples. The Dysmorphic Concerns Questionnaire (DCQ) was developed to assess dysmorphic concern and to date has only been psychometrically validated in adult samples. The aim of the current study was to examine the psychometric properties of the DCQ to ensure it is suitable for clinical use with adolescent and young adult patients. Method One hundred and ninety-five individuals aged 12–21 years (M = 18.25, SD = 2.51; 59% female) participated in the study. Results The DCQ demonstrated a unidimensional construct [χ2 (14) = 24.59, p = .04; RMSEA =.06, SRMR =.02 and CFI =.99], with good internal consistency (α = .88). The DCQ also showed high convergent validity with measures of BDD symptomatology, however, divergent validity was not supported in this study. Known-groups validity of the DCQ was established, with a large effect size (d = 1.28). Conclusions These findings indicate that the DCQ is a brief, reliable, and valid measure that is appropriate to screen for symptoms of BDD in adolescent and young adults and to monitor symptom change during treatment. KEY POINTS What is already known about this topic: Body dysmorphic disorder is a mental health condition which results in significant functional impairment. The Dysmorphic Concerns Questionnaire (DCQ) is a psychometrically sound measure of dysmorphic concern. Body dysmorphic disorder commonly occurs in adolescence. What this topic adds: (1) This is the first study to evaluate the psychometric properties of the DCQ in a sample of adolescents and young adults. (2) The psychometric properties of the DCQ are similar in adult and adolescent/young adult samples. (3) The DCQ is appropriate to use with adolescent and young adult patients.

青少年和年轻人畸形担忧问卷（DCQ）的心理测量学验证

【摘要】目的身体畸形障碍(BDD)是一种慢性心理健康状况，其症状通常出现在青春期早期。尽管发病于青春期，但大多数自我报告的BDD严重程度测量尚未在青少年和年轻成人样本中得到验证。畸形关注问卷(DCQ)是为了评估畸形关注而开发的，迄今为止只在成人样本中进行了心理测量学验证。当前研究的目的是检查DCQ的心理测量特性，以确保它适用于青少年和年轻成人患者的临床应用。方法12 ~ 21岁个体195例(M = 18.25, SD = 2.51;(59%为女性)参与了这项研究。结果DCQ呈单维结构[χ2 (14) = 24.59, p = 0.04;RMSEA =。6、SRMR =。02和CFI =。99]，具有良好的内部一致性(α = 0.88)。DCQ也显示出与BDD症状测量的高收敛效度，然而，本研究不支持发散效度。DCQ的已知组效度成立，具有较大的效应量(d = 1.28)。结论DCQ是一种简单、可靠、有效的测量方法，适用于青春期和青壮年BDD的症状筛查和治疗过程中症状变化的监测。关于这个话题已经知道的:身体畸形障碍是一种导致严重功能损害的精神健康状况。畸形关注问卷(DCQ)是一种心理计量学上健全的畸形关注量表。身体畸形症通常发生在青春期。本课题补充的内容:(1)这是第一个在青少年和年轻人样本中评估DCQ心理测量特性的研究。(2)在成人和青少年样本中，DCQ的心理测量特征相似。(3) DCQ适用于青少年和青壮年患者。
