Despite the high rates of suicidality in body dysmorphic disorder and eating disorders (EDs), research on suicidality in a related disorder, muscle dysmorphia (MD), is essentially nonexistent. Thus, this study tested relations between suicidal thoughts and behaviors and MD and ED symptoms in an online male community sample.
A total of 464 males (M = 40.3; 85% Caucasian) recruited from Amazon's Mechanical Turk completed measures that evaluated ED symptoms, MD symptoms, current suicidal ideation, and past suicide attempts.
Most MD and ED symptoms were correlated with current suicidal ideation and previous suicide attempts. In multivariate regression models, vomiting and appearance intolerance remained significantly related to suicidal ideation, while hard exercise and lower functional impairment were significantly related to prior suicide attempts.
Results indicate that appearance dissatisfaction, a core MD criterion, and hard exercise, a common behavioral symptom of MD, are associated with suicidality.
尽管在躯体变形障碍和饮食障碍(ED)中自杀率很高,但与相关障碍——肌肉变形障碍(MD)相关的自杀研究实际上还不存在。因此,本研究在一个男性在线社区样本中测试了自杀想法和行为与 MD 和 ED 症状之间的关系。
共有 464 名男性(M=40.3;85%为白种人)从亚马逊的 Mechanical Turk 上招募,他们完成了评估 ED 症状、MD 症状、当前自杀意念和过去自杀企图的量表。
大多数 MD 和 ED 症状与当前自杀意念和过去自杀企图相关。在多元回归模型中,呕吐和外貌不耐受与自杀意念显著相关,而剧烈运动和较低的功能障碍与之前的自杀企图显著相关。
结果表明,对外貌的不满,MD 的一个核心标准,以及 MD 的常见行为症状——剧烈运动,与自杀意念相关。
