A new measure specifically designed for adolescents to assess body dysmorphic disorder (BDD) symptoms is needed to identify youth who could benefit from intervention to reduce their BDD-related symptomology. To address this gap, the Multidimensional Youth Body Dysmorphic Inventory (MY BODI) was developed and the psychometric properties were evaluated. Following development and expert assessment, Australian secondary school students (N = 582; 55% female; M = 13.62, SD = 1.59, aged 11 to 18 years, grades 7 to 12) completed a survey with the new items and validation measures. Results from the factor analysis supported a 3-factor, 21-items measure, which aligned with the DSM-5 diagnostic criteria of Impairment/avoidance, Preoccupation/repetitive behaviours, and Insight/distress. Supporting the convergent validity of the measure, the MY BODI total score and sub-scale scores correlated with measures of BDD symptoms, including the Appearance Anxiety Inventory (AAI) and Body Dysmorphic Disorder Questionnaire-Adolescent Version (BDDQ-A). This study provides preliminary validation of the MY BODI, a self-report measure of BDD symptoms and symptom severity, using a response set aimed to facilitate more reliable reporting, which may identify risk for BDD, and symptoms of BDD.
需要一种专门为青少年设计的新措施来评估体像障碍 (BDD) 症状，以确定那些可能受益于干预措施以减少 BDD 相关症状的年轻人。为了解决这一差距，开发了多维青少年体像障碍量表 (MY BODI)，并评估了其心理测量特性。在开发和专家评估之后，澳大利亚中学生 (N=582; 55%为女性; M=13.62, SD=1.59, 年龄 11 至 18 岁，7 至 12 年级) 完成了一项包含新条目和验证性测量的调查。因子分析的结果支持一个 3 因素 21 项的测量，与 DSM-5 的诊断标准相一致，包括损伤/回避、专注/重复行为和洞察力/痛苦。该测量的聚合效度得到支持，MY BODI 总分和子量表得分与 BDD 症状的测量方法相关，包括外貌焦虑量表 (AAI) 和青少年版体像障碍问卷 (BDDQ-A)。这项研究使用旨在促进更可靠报告的反应集，初步验证了 MY BODI，这是一种 BDD 症状和症状严重程度的自我报告测量，可能识别 BDD 的风险和 BDD 的症状。
