Relative Importance of Self-Disgust as a Predictor of Self-Injurious Thoughts and Behaviors among Young Adults

Introduction: Self-injurious thoughts and behaviors (SITBs) are prevalent among young adults. This study aimed to explore self-disgust as a potential correlate and predictor of SITBs. Methods: Participants were recruited on a college campus. One hundred and sixteen participants (62% female-identifying, 51% Caucasian, 40% LGBTQ+, Mage = 19.68, SD = 1.41) completed assessments. Results: Participants with a history of SITBs had significantly higher self-disgust scores than those without. Self-disgust was significantly associated with other demographic (e.g., LGBTQ+ identity), psychological (e.g., experiential avoidance), and clinical (e.g., history of psychopathology) variables. Multivariable logistic regression analyses showed that even when adjusting for other strong correlates, self-disgust remained a significant predictor of SITB history (yes/no). Further, self-disgust outperformed all other variables in the model on multiple metrics of relative importance. Conclusions: Findings suggest the significance of self-disgust as an important emotion in further understanding, and potentially predicting, SITBs among young adults.

研究背景：自我伤害想法与行为（Self-injurious Thoughts and Behaviors，SITBs）在青年群体中具有较高流行率。本研究旨在探讨自我厌恶作为自我伤害想法与行为潜在相关因素及预测因子的作用。研究方法：研究对象通过校园渠道招募，共纳入116名参与者（其中62%为女性身份认同者，51%为高加索裔，40%为女同性恋、男同性恋、双性恋与跨性别群体（LGBTQ+），平均年龄为19.68岁，标准差为1.41），所有参与者均完成了相关评估。研究结果：有自我伤害想法与行为史的参与者，其自我厌恶得分显著高于无该行为史的参与者；自我厌恶与多项人口统计学变量（如LGBTQ+身份认同）、心理学变量（如经验性回避）及临床变量（如精神病理学病史）均存在显著关联。多变量逻辑回归分析显示，即便在控制其他强相关变量后，自我厌恶仍为自我伤害想法与行为史（是/否）的显著预测因子；此外，在多项相对重要性评估指标中，自我厌恶的表现均优于模型中的其他变量。研究结论：本研究结果表明，自我厌恶作为一种关键情绪，对于进一步理解青年群体的自我伤害想法与行为，乃至潜在实现该行为的早期预测均具有重要价值。
