The current study aimed to examine the factor structure, reliability, and validity of 3 measures of body image disturbance (body image flexibility, body avoidance, and body checking) considered to be relevant to eating disorder psychopathology, with the aim of determining the optimal structure of each for use in treatment planning and outcome monitoring. Additionally, the study aimed to identify which factors had the strongest association with disordered eating. Participants were 328 female undergraduate university students aged 17-25 years. Confirmatory factor analyses were conducted followed by correlational, regression, and test analyses. The original proposed models were retained for the body image flexibility and body checking measures, while an alternative model was supported for the body image avoidance measure. All 3 solutions were found to have acceptable validity and reliability. Scores on each measure differed significantly between normal and disordered eaters. The body image flexibility measure and selected subscales of the body image avoidance and checking measures had unique associations with eating disorder psychopathology and psychosocial impairment. Results of this study indicate how the assessment of body image can be achieved in treatment of eating disorders in such a way as to reduce participant burden while adequately assessing the body image disturbance that is characteristic of eating disorders.

本研究旨在考察 3 种被认为与饮食障碍病理相关的身体意象障碍测量方法（身体意象灵活性、身体回避和身体检查）的结构、信度和效度，目的是确定每种方法在治疗计划和结果监测中的最佳结构。此外，本研究还旨在确定与饮食障碍关系最密切的因素。参与者为 328 名年龄在 17-25 岁的女性大学生。进行了验证性因子分析，然后进行了相关、回归和 t 检验分析。身体意象灵活性和身体检查测量方法保留了最初提出的模型，而身体意象回避测量方法则支持替代模型。所有 3 种解决方案都被发现具有可接受的有效性和可靠性。每个测量方法的得分在正常和饮食失调者之间存在显著差异。身体意象灵活性测量方法以及身体意象回避和检查测量方法的一些特定分量表与饮食障碍病理和心理社会障碍有独特的关联。本研究的结果表明，如何在治疗饮食障碍时评估身体意象，既能减轻参与者的负担，又能充分评估饮食障碍特有的身体意象障碍。
