Muscle dysmorphia (MD) is a body image disturbance characterized by a pathological preoccupation with muscularity. The study aimed to differentiate the levels of risk for MD among weightlifters and to define a tentative cut-off score for the Muscle Appearance Satisfaction Scale (MASS) for the identification of high risk MD cases. Hungarian male weightlifters (n=304) completed the MASS, the Exercise Addiction Inventory, and specific exercise and body image related questions. For the differentiation of MD, factor mixture modeling was performed, resulting in three independent groups: low-, moderate-, and high risk MD groups. The estimated prevalence of high risk MD in this sample of weightlifters was 15.1%. To determine a cut-off score for the MASS, sensitivity and specificity analyses were performed and a cut-off point of 63 was suggested. The proposed cut-off score for the MASS can be useful for the early detection of high risk MD.
肌肉变形障碍（MD）是一种身体意象障碍，其特征是病理性地专注于肌肉发达。本研究旨在区分举重运动员患 MD 的风险水平，并为肌肉外观满意度量表（MASS）定义一个暂定的截断分数，以识别 MD 高危病例。匈牙利男性举重运动员（n=304）完成了 MASS、运动成瘾量表以及特定的运动和身体意象相关问题。为了区分 MD，进行了因子混合模型分析，结果产生了三个独立的组：低、中、高 MD 风险组。在这个举重运动员样本中，高危 MD 的估计患病率为 15.1%。为了确定 MASS 的截断分数，进行了敏感性和特异性分析，建议截断分数为 63。MASS 的建议截断分数可用于早期发现 MD 高危病例。
