Risky decision-making putatively contributes to nonsuicidal self-injury (NSSI) yet empirical support for this association is inconsistent. Studies have not simulated socioemotional contexts most closely linked to NSSI, which may partially explain mixed findings. Accordingly, we examined the association between NSSI and risky decision-making following the receipt of criticism from a close other, a key interpersonal context. The study included 286 university students (Mage = 21.11) oversampled for a lifetime history of NSSI. Participants completed a modified Iowa Gambling Task, in which they chose to play or pass on "good" and "bad" decks associated with monetary gains and losses. Participants also completed the Criticism Gambling Task, which was identical to the Iowa Gambling Task except critical audio comments preceded each block of trials. Based on results of multilevel growth curve analyses, decreases in risky decision-making were steeper on the Iowa Gambling Task compared to the Criticism Gambling Task, suggesting poorer learning in the context of criticism. Further, how past-month NSSI was related to changes in risky decision-making across blocks differed between the two tasks, b = -0.004, t(3140.00) = 2.48, p = .013. On the Iowa Gambling Task, all participants decreased their risky decision-making, whereas on the Criticism Gambling Task, higher past-month NSSI frequencies were associated with riskier decision-making. Our findings support associations between risky decision-making and NSSI in negative socioemotional contexts, consistent with functional models of NSSI.
冒险决策据称与非自杀性自我伤害（NSSI）有关，但这种关联的实证支持并不一致。研究尚未模拟与 NSSI 最密切相关的社会情感背景，这可能部分解释了混合结果。因此，我们在收到亲密他人的批评后，检查了 NSSI 与冒险决策之间的关联，这是与 NSSI 密切相关的一个关键人际背景。该研究包括 286 名大学生（Mage = 21.11），对他们进行了终生 NSSI 史的抽样调查。参与者完成了一个改良的爱荷华赌博任务，在这个任务中，他们选择玩或不玩与金钱得失相关的“好”和“坏”牌组。参与者还完成了批评赌博任务，该任务与爱荷华赌博任务相同，只是在每个试验块之前都有批评性的音频评论。基于多层次增长曲线分析的结果，在爱荷华赌博任务中，冒险决策的下降幅度比批评赌博任务陡峭，这表明在批评的情况下学习能力较差。此外，过去一个月 NSSI 与不同任务中各块之间冒险决策变化的关系也不同，b = -0.004，t(3140.00) = 2.48，p =.013。在爱荷华赌博任务中，所有参与者都减少了他们的冒险决策，而在批评赌博任务中，过去一个月 NSSI 频率较高与更冒险的决策有关。我们的发现支持了冒险决策与负面社会情感背景下 NSSI 之间的关联，这与 NSSI 的功能模型一致。
