Limited information is available on understanding why particular individuals engage in non-suicidal deliberate self-harm (DSH), especially among non-clinical populations. An array of personality traits, such as those included in the five-factor model of personality, may further an understanding of DSH. The purpose of this study was to examine personality traits among non-clinical groups with or without a history of DSH. College students (N=238) completed self-report measures of DSH and personality. Both multivariate (MANOVA, discriminant analysis) and univariate (ANOVA) statistical procedures supported the hypothesis that those with a history of DSH (n=59) had significantly higher levels of neuroticism and openness to experience, and significantly lower levels of agreeableness and conscientiousness. Contrary to expectations, there were no differences in extraversion between the two groups. These results indicate personality differences among those with a history of DSH, which with additional research, may prove to be risk factors or targets of intervention for future DSH or collateral problems.
关于特定个体为何会进行非自杀性蓄意自伤（DSH），尤其是在非临床人群中，目前可得信息有限。一系列人格特质，比如人格五因素模型中包含的那些特质，可能有助于加深对非自杀性蓄意自伤的理解。本研究的目的是检验有或无非自杀性蓄意自伤史的非临床群体的人格特质。大学生（N = 238）完成了关于非自杀性蓄意自伤和人格的自我报告测量。多变量（多变量方差分析、判别分析）和单变量（方差分析）统计程序均支持了这一假设，即有非自杀性蓄意自伤史的人（n = 59）神经质水平和经验开放性显著更高，宜人性和尽责性水平显著更低。与预期相反，两组在外倾性上没有差异。这些结果表明有非自杀性蓄意自伤史的人群存在人格差异，经过进一步研究，这些差异可能会被证明是未来非自杀性蓄意自伤或相关问题的风险因素或干预目标。
