Non-suicidal self-injury (NSSI) has consistently been associated with self-reported difficulties in emotion reactivity and the regulation of negative emotions; however, less is known about the accuracy of these self-reports or the reactivity and regulation of positive emotions. The present study sought to investigate differences between women with and without a history of NSSI on: (a) self-reported general tendencies of negative and positive emotion reactivity, (b) self-reported general tendencies of negative and positive emotion regulation, and (c) emotion regulation reported in response to a positive and negative mood induction. The sample consisted of 36 women with a recent history of NSSI within the last 2 years ( = 20.06; = 1.51) and a comparison group with no history of NSSI ( = 34; = 20.15; = 1.54). Participants completed self-report measures of negative and positive emotion reactivity and regulation. In a separate session, participants underwent both a negative and positive mood induction using a counterbalanced design and reported their experienced emotions. Results from two-way MANOVAs and ANOVAs revealed those with a history of NSSI reported significantly greater difficulties in negative emotion reactivity and regulation than the no-NSSI comparison group; however, no group differences emerged in self-reported reactivity or regulation of positive emotions. In contrast, repeated measures ANOVAs on data from the mood induction task found no group differences in reactivity or regulation for either negative or positive emotions. These findings highlight the possibility that although individuals with a history of NSSI evaluate their ability to manage negative emotions as significantly worse than individuals with no history of self-injury, this may not reflect their actual emotion regulatory processes.
非自杀性自伤（NSSI）一直与自我报告的情绪反应困难以及负面情绪调节困难有关；然而，对于这些自我报告的准确性或积极情绪的反应性和调节知之甚少。本研究旨在调查有和没有NSSI病史的女性在以下方面的差异：（a）自我报告的负面和正面情绪反应的一般倾向，（b）自我报告的负面和正面情绪调节的一般倾向，以及（c）在正负情绪诱导后报告的情绪调节。样本包括36名在过去2年内有近期NSSI病史的女性（年龄=20.06岁；标准差=1.51）和一个没有NSSI病史的对照组（年龄=34岁；年龄=20.15岁；标准差=1.54）。参与者完成了负面和正面情绪反应及调节的自我报告测量。在另一次会议中，参与者采用平衡设计接受了负面和正面情绪诱导，并报告了他们体验到的情绪。双向多变量方差分析和方差分析的结果显示，有NSSI病史的人在负面情绪反应和调节方面报告的困难明显大于无NSSI对照组；然而，在自我报告的积极情绪反应或调节方面没有出现组间差异。相比之下，对情绪诱导任务数据进行的重复测量方差分析发现，在负面或正面情绪的反应性或调节方面没有组间差异。这些发现凸显了这样一种可能性，即尽管有NSSI病史的个体认为自己管理负面情绪的能力明显比没有自伤病史的个体差，但这可能并不反映他们实际的情绪调节过程。
