Abstract

Non-suicidal self-injury (NSSI) is a common behavior, particularly among adolescents and young adults. Impulsivity has been implicated as an important factor associated with NSSI, however prospective longitudinal research is lacking. Moreover, the relationship between impulsivity and other risk factors for NSSI is unclear. By examining longitudinal models including impulsivity, attachment, and distress we hope to elucidate the nature of the association between impulsivity and NSSI. 1,686 community-recruited young people (ages 14–25) with no NSSI in the past year were followed up for one year, completing self-report measures of the above factors. Impulsivity independently predicted new onset of NSSI over and above other risk factors, indicating heightened impulsivity is a prospective risk factor for NSSI. Psychological distress mediated the parenting-NSSI association.

摘要

非自杀性自伤 (NSSI) 是一种常见行为，尤其是在青少年和年轻人中。冲动性被认为是与 NSSI 相关的一个重要因素，但缺乏前瞻性纵向研究。此外，冲动性与 NSSI 的其他危险因素之间的关系尚不清楚。通过检查包括冲动、依恋和痛苦在内的纵向模型，我们希望阐明冲动与 NSSI 之间关联的性质。对1686名社区招募的近一年无NSSI的青年（14-25岁）进行了为期一年的随访，完成了上述因素的自我报告测量。冲动性独立预测了 NSSI 的新发作，超过了其他风险因素，表明冲动性增强是 NSSI 的潜在风险因素。
