摘要

Childhood neglect is a well-established risk factor for non-suicidal self-injury (NSSI) in adolescents, yet the contributions of impulsivity and sleep problems within this relationship are not yet fully elucidated. This study aimed to explore if childhood neglect indirectly influences NSSI through impulsivity and to assess whether sleep problems moderate both the direct and indirect links between childhood neglect and NSSI across a 12-month period. A total of 1,987 adolescents (43.87% female, aged 10–14 years) participated in the study, completing questionnaires on childhood neglect, impulsivity, sleep problems, and NSSI across three waves. Baseline measures, along with age, gender, and socioeconomic status (SES), were included as covariates. A positive association between childhood neglect and NSSI was revealed, with impulsivity serving as a mediator in this relationship (indirect effect = 0.01, p < 0.05). Additionally, sleep problems moderated both the direct and indirect effects, amplifying the association between childhood neglect and NSSI, particularly at higher levels of sleep problems. These results underscore the importance of targeting impulsivity and sleep issues in interventions aimed at reducing NSSI risk for adolescents who have experienced neglect during childhood.
