The affective states most strongly associated with nonsuicidal self-injury (NSSI) remain poorly understood, particularly among veterans. This study used ecological momentary assessment (EMA) to examine relationships between affect ratings and NSSI urges and behaviors among veterans with NSSI disorder.
Participants (N = 40) completed EMA entries via mobile phone for 28 days (3722 total entries). Entries included intensity ratings for five basic affective states, as well as NSSI urges and behaviors, during the past 4 hours.
Bivariate analyses indicated that each affect variable was significantly associated with both NSSI urges and behaviors. Angry/hostile and sad were most strongly associated with both NSSI urges and behaviors. A multivariate regression revealed that angry/hostile, disgusted with self, and happy (inversely related) were contemporaneously (within the same period) associated with NSSI behaviors, whereas all five basic affective states were contemporaneously associated with NSSI urges. In a lagged model, angry/hostile and sad were associated with subsequent NSSI urges but not behaviors.
Findings highlight the relevance of particular affective states to NSSI and the potential utility of targeting anger in treatments for NSSI among veterans. There is a need for future EMA research study to further investigate temporal relationships between these variables.
与非自杀性自伤（NSSI）最密切相关的情感状态仍未被充分理解，尤其是在退伍军人中。本研究使用生态瞬时评估（EMA）来检查 NSSI 障碍退伍军人的情感评分与 NSSI 冲动和行为之间的关系。
参与者（N=40）通过手机完成了 28 天的 EMA 条目（共 3722 个条目）。条目包括过去 4 小时内五种基本情感状态的强度评分，以及 NSSI 冲动和行为。
双变量分析表明，每个情感变量都与 NSSI 冲动和行为显著相关。愤怒/敌意和悲伤与 NSSI 冲动和行为最密切相关。多元回归显示，愤怒/敌意、自我厌恶和快乐（负相关）与 NSSI 行为同时（同一时期）相关，而五种基本情感状态都与 NSSI 冲动同时相关。在滞后模型中，愤怒/敌意和悲伤与随后的 NSSI 冲动有关，但与行为无关。
研究结果强调了特定情感状态与 NSSI 的相关性，以及针对退伍军人 NSSI 中愤怒的治疗的潜在效用。需要进一步的 EMA 研究来进一步调查这些变量之间的时间关系。
