Harsh parenting and adolescents’ nonsuicidal self-injury: Rejection sensitivity and depression as serial mediators

We conducted this study to explore effective ways to reduce adolescents’ nonsuicidal self-injury (NSSI). Grounded in the four-function model of NSSI, this study examined the effect of negative parenting styles, relationship insecurity, and emotional problems on NSSI among 1,408 adolescents in China. The results showed that harsh parenting, rejection sensitivity, and depression significantly and positively predicted NSSI. Further, rejection sensitivity and depression acted as both independent and serial mediators in the association between harsh parenting and NSSI. Our findings provide direct and indirect paths to reduce NSSI among adolescents, and provide a basis for future interventions.
