非自杀性自伤(NSSI)是一种普遍的行为,尤其是在年轻人中。然而,人们对 NSSI 的潜在机制或这些行为的性格相关性知之甚少。本研究的目的是探讨行为激活和抑制系统(BAS 和 BIS)在 NSSI 中的作用。共有 604 名本科生完成了 BAS 和 BIS 两项自我报告测量,以及 NSSI 历史。 Logistic 和负二项式线性回归用于检查 BAS 和 BIS 测量值与 NSSI 的存在和病程特征之间的关系。大约 30% 的参与者报告有 NSSI 病史。 BAS(驱动力、奖励和寻求乐趣)的高分与 BIS 总分的低分相结合,预测了 NSSI 历史。然而,反之亦然,BIS 总量水平较高,而 BAS(驱动力、奖励和寻求乐趣)水平较低,也可以预测 NSSI 历史。此外,BIS 的一些 BAS 交互预测了 NSSI 过程,其特征是使用更多的行为和方法。这项研究支持 BAS 和 BIS 在 NSSI 中的作用,并在确定这些性格相关性如何帮助识别有 NSSI 风险的个体方面迈出了第一步。
Non-suicidal self-injury (NSSI) is a prevalent behaviour, particularly among young adults. Little is known, however, about the mechanisms underlying NSSI or the personality correlates of these behaviours. The goal of this study was to examine the roles of the behavioural activation and inhibition systems (BAS and BIS) in NSSI. A total of 604 undergraduates completed two self-report measures of BAS and BIS, as well as NSSI history. Logistic and negative binomial linear regressions were used to examine the relationships between measures of BAS and BIS and the presence and course characteristics of NSSI. Approximately 30% of participants reported a history of NSSI. High scores on BAS (drive, reward and fun seeking), combined with low scores on BIS total, predicted NSSI history. However, the opposite was also true, with high levels of BIS total, combined with low levels of BAS (drive, reward and fun seeking), also predicting NSSI history. In addition, several BAS by BIS interactions predicted an NSSI course characterized by more acts and methods used. This study supports the roles of both BAS and BIS in NSSI and takes the first step in identifying how these personality correlates may help identify individuals at risk for NSSI.
