迄今为止，关于非自杀性自伤（NSSI）预测因素的大量研究已经将NSSI概念化为一个单一的结构，尽管NSSI可以以多种形式存在（例如，击打、切割、燃烧）。本研究的目的是研究不同形式的NSSI的差分预测。具体来说，我们研究了特质攻击作为更积极形式的NSSI的预测因子（即，hitting）。我们假设，较高的特质攻击性将区分那些从事打击形式的NSSI的人和那些没有的人，而其他因素（即，情绪调节和特质愤怒）将作为一个非特异性预测的NSSI。我们还假设，更高的特质攻击性与一生中打NSSI的频率有关，但与其他形式的NSSI无关，而情绪调节和愤怒将作为其他形式的NSSI的预测因子。为了验证这些假设，一个大样本的年轻人完成了特质攻击，特质愤怒，情绪调节和NSSI行为的措施。结果基本符合我们的假设。高水平的特质攻击区分那些谁从事打NSSI从那些谁没有，也与更大的频率打NSSI。这些结果意味着，不同的因素预测不同形式的NSSI和NSSI可能是最好的检查作为一个多方面的建设。
To date, the considerable body of research on predictors of non-suicidal self-injury (NSSI) has conceptualized NSSI as a unitary construct despite the fact that NSSI can exist in many forms (e.g., hitting, cutting, burning). The goal of the present study is to examine differential prediction of forms of NSSI. Specifically, we examined trait aggression as a predictor of more aggressive forms of NSSI (i.e., hitting). We hypothesized that higher trait aggression would differentiate those who engaged in hitting forms of NSSI from those who did not, whereas other factors (i.e., emotion regulation and trait anger) would serve as a non-specific predictor of NSSI. We also hypothesized that higher trait aggression would be related to lifetime frequency of hitting NSSI, but not other forms of NSSI, whereas emotion regulation and anger would act as predictors of other forms of NSSI. To test these hypotheses, a large sample of young adults completed measures of trait aggression, trait anger, emotion regulation, and NSSI behaviors. Results were generally in line with our hypotheses. Higher levels of trait aggression differentiated those who engaged in hitting NSSI from those who did not and was also associated with greater frequency of hitting NSSI. These results imply that different factors predict different forms of NSSI and that NSSI may be best examined as a multi-faceted construct.
