Approximately 10% to 30% of individuals with eating disorders (EDs) are male, yet because measures often have not been tested among male participants, it is unclear whether the psychometric properties of ED measures are equivalent between sexes. The purpose of this study was to compare the test-retest reliability of common ED measures in men versus women. Participants ( N = 227; 58.1% female) completed self-report measures of body dissatisfaction, restrained eating, disinhibited eating, bulimic symptoms, and desire-for-muscularity at baseline and 2-to-4 weeks later. Intraclass correlations were used to compute retest correlations. Spearman's rho was used to compute retest correlations for skewed and kurtotic variables. We compared 95% confidence intervals for intraclass correlation coefficients to determine whether measures differed in reliability between sexes. Most ED measures had at least acceptable test-retest reliabilities. However, few measures of disinhibited and binge eating demonstrated good reliability in men. Results highlight the utility of several ED measures for assessing symptom change over time, and the need for additional research to identify and correct for sources of gender unreliability among ED self-report measures in men-particularly for assessing constructs that include binge-eating behavior.
大约 10%至 30%的进食障碍（ED）患者为男性，但由于针对男性参与者的测量方法通常未经测试，因此尚不清楚 ED 测量方法的心理测量特性在性别之间是否相同。本研究的目的是比较男性和女性中常见 ED 测量方法的重测信度。参与者（N=227；58.1%为女性）在基线和 2 至 4 周后完成了对身体不满、节食、放纵饮食、暴食症状和对肌肉发达的渴望的自我报告测量。使用组内相关系数计算重测相关性。对于偏态和峰态变量，使用 Spearman rho 计算重测相关性。我们比较了组内相关系数的 95%置信区间，以确定测量方法在性别之间的可靠性是否存在差异。大多数 ED 测量方法至少具有可接受的重测信度。然而，在男性中，很少有测量放纵和暴食的方法具有良好的可靠性。结果突出了几种 ED 测量方法在评估随时间变化的症状方面的效用，并且需要进行额外的研究，以确定和纠正男性 ED 自我报告测量方法中性别不可靠的来源，特别是在评估包括暴食行为的构念时。
