Disgust has been implicated as a factor that maintains and exacerbates eating disorder (ED) symptoms. Emerging research suggests that disgust may be a risk factor for suicidality. Given the high rates of suicidality among individuals with EDs, we propose that disgust may contribute to the link between EDs and suicidality. To test this hypothesis, self-report data were collected from 341 young adults (66% women). Cross-sectional associations between disgust with the self, others and the world and disgust sensitivity and propensity, ED symptoms and suicidal ideation were examined using multivariate regression analyses. ED symptoms and body dissatisfaction were associated with increased suicidal ideation at high levels of disgust with the self and the world; at low levels of disgust, ED symptoms and body dissatisfaction did not significantly relate to suicidal ideation. Disgust may indicate risk for suicidal ideation among individuals with eating psychopathology.
厌恶被认为是维持和加剧饮食失调（ED）症状的一个因素。新出现的研究表明，厌恶可能是自杀倾向的一个风险因素。鉴于饮食失调患者的自杀率很高，我们提出厌恶可能导致饮食失调与自杀倾向之间的联系。为了验证这一假设，我们收集了341名年轻人（66%为女性）的自我报告数据。使用多元回归分析检验了对自我、他人和世界的厌恶以及厌恶敏感性和倾向、饮食失调症状和自杀意念之间的横断面关联。在对自我和世界高度厌恶的情况下，饮食失调症状和身体不满与自杀意念增加有关；在低厌恶水平下，饮食失调症状和身体不满与自杀意念没有显著关联。厌恶可能表明有饮食心理病理学的个体存在自杀意念风险。
