Bulimia nervosa and non-suicidal self-injury (NSSI) co-occur at high rates, and both have been conceptualized as maladaptive emotion regulation strategies. Treatments focusing on emotion regulation have been designed for both problem behaviors, yet, there exists very little research examining the temporal emotional states surrounding acts of NSSI. Using ecological momentary assessment (EMA) methodology, the current study examined the temporal association between positive and negative emotional states prior to and consequent to acts of NSSI within a subset of bulimia nervosa patients. Results indicate significant increases in negative affect, and decreases in positive affect, prior to an NSSI act. Post-NSSI, positive affect significantly increased while negative affect remained unchanged. The findings offer partial support for an emotion regulation paradigm to understanding NSSI within bulimic populations and implications for treatment are discussed.
神经性贪食症与非自杀性自伤行为（NSSI）的共病率很高，二者都被视为适应不良的情绪调节策略。针对这两种问题行为，已经设计出了聚焦于情绪调节的治疗方法。然而，很少有研究考察非自杀性自伤行为发生时的即时情绪状态。本研究采用生态瞬时评估（EMA）方法，在一部分神经性贪食症患者中，考察了非自杀性自伤行为前后的正负性情绪状态之间的即时关联。结果表明，在非自杀性自伤行为之前，消极情绪显著增加，积极情绪减少。在非自杀性自伤行为之后，积极情绪显著增加，而消极情绪保持不变。这些发现为情绪调节范式理解贪食症人群中的非自杀性自伤行为提供了部分支持，并讨论了其对治疗的启示。
