Analysis of non-suicidal self-injury and its association with negative life events among college students

Objective To discuss non-suicidal self-injury(NSSI) and its association with life events among college students. Methods Using the cluster sampling, 1988 college students from two universities were administered by a designed questionnaire, which included Self-injury subscale and Adolescent Self Rating Life Events Check List. Multiple logistic regressions were used to analyze the relationship between non-suicidal self-injury and life events. Results 176(10.5%) participants engaged non-suicidal self-injury in past 12 months. The total and subscales scores of ASLEC in college students who engaged NSSI were significantly higher than who denied NSSI(all P<0.05). Multiple Logistic regression suggested that interpersonal relationship factor and punishment factor were associated with NSSI(all P<0.05). Conclusions NSSI is significantly associated with life events,which may increase the risk of NSSI among college students.
