Negative life events and non-suicidal self-injury in an adolescent inpatient sample.

Although life stressors have been implicated in the aetiology of various forms of psychopathology related to non-suicidal self-injury (NSSI), particularly depression and suicidal behavior, they have rarely been examined in relation with NSSI. The objective of the current study was to assess the association between life stressors and NSSI in adolescent inpatients. Adolescent inpatients (n = 110) completed measures of life events, NSSI, and depressive symptoms at 3 time-points over a 9-month period. Higher rates of life stressors were significantly associated with greater NSSI. This finding held even after covarying concurrent depressive symptoms and gender. Life stressors may have a unique role in the pathogenesis of NSSI. Directions for future research and clinical implications are discussed.
