This study examined the prospective and reciprocal relationships among perceived parental control, self-criticism, and nonsuicidal self-injury (NSSI). We also examined the mediating effect of self-criticism in the relationship between perceived parental control and NSSI. We aimed to find out whether perceived parental control and self-criticism acted as risk factors for NSSI, or consequences of NSSI, or both. A group of 3,600 Chinese adolescents (mean age = 14.63 years, 56.6% female) completed questionnaires, with measures assessing NSSI, self-criticism, and parental control. A cross-lag model was used to test the reciprocal relationships among variables at 3 time points with 6-month intervals. Perceived parental control and self-criticism did not reliably predict later NSSI, but NSSI predicted later perceived parental control and self-criticism. Findings of this study emphasize the adverse effects of NSSI, and shed light on the intervention efforts of this behavior.
