Abstract

Nonsuicidal self-injury (NSSI) is theorized to be caused by negative associations with the self, including low self-esteem, but the mechanisms explaining why low self-esteem is related to more severe NSSI are unclear. The current study aimed to address this limitation by evaluating a mediation model, proposing that low self-esteem would relate to more severe NSSI through increasing self-punishment motivations. Data came from 468 undergraduate students with a history of NSSI who completed an online survey measuring NSSI characteristics and functions, self-esteem, and self-punishment motivations for NSSI. Mediation was tested using a structural equation model using bootstrapped 95% percentile-corrected confidence intervals in which NSSI severity was modeled as a latent variable composed of NSSI frequency, recency, and versatility of methods. The total model was significant and the indirect effect of self-esteem on NSSI severity through self-punishment motives was significant. Self-esteem also retained significant direct effects on NSSI severity, indicating partial mediation. These results provide support for the benefits and barriers model of NSSI, suggesting that negative self-views increase risk for more severe NSSI through self-punishment motivations. Clinical interventions that emphasize self-compassion and focus on modifying self-punishment motivations may help reduce NSSI behavior.

消极的自我认知与 NSSI 的严重程度:测试利益与障碍模型。
据推测,非自杀性自伤(NSSI)是由包括低自尊在内的自我负面联想引起的,但低自尊与更严重的非自杀性自伤之间的关系机制尚不清楚。本研究旨在通过评估一个中介模型来解决这一局限性,该模型认为低自尊会通过增加自我惩罚动机而与更严重的NSSI有关。数据来自 468 名有 NSSI 史的本科生,他们完成了一项在线调查,调查内容包括 NSSI 特征和功能、自尊以及 NSSI 的自我惩罚动机。我们使用了一个结构方程模型来测试中介作用,该模型使用了自引导的 95% 百分位数校正置信区间,将 NSSI 严重程度作为一个潜变量建模,该潜变量由 NSSI 频度、发生频率和方法的多样性组成。总模型是显著的,自尊通过自我惩罚动机对 NSSI 严重程度的间接影响是显著的。自尊对 NSSI 严重程度的直接影响也很明显,表明存在部分中介作用。这些结果为 NSSI 的益处和障碍模型提供了支持,表明消极的自我观点会通过自我惩罚动机增加更严重 NSSI 的风险。强调自我同情并注重改变自我惩罚动机的临床干预措施可能有助于减少 NSSI 行为。
