Abstract:

To investigate the changing trends in adolescent self-injury (NSSI, hereinafter referred to as self- injury) and their macro-level influencing factors, a cross-temporal meta-analysis was conducted on studies that used the Adolescents Self-Harm Scale as the measurement tool. The findings indicated that: (1) From 2013 to 2022, the self-injury level among Chinese adolescents showed a gradual declining trend; (2) Economic development, Internet penetration rate, and the number of relevant policies signi?cantly predicted the decrease in self-injury levels; (3) Policy interventions required approximately three years to achieve a significant reduction in adolescent self-injury; (4) Age positively predicted self-injury levels; (5) No signi?cant overall di?erences were found in self-injury levels by gender or place of origin.
