Background: Non-suicidal self-injury (NSSI) is a significant public health issue that threatens the physical and mental well-being of adolescents. Identifying associated factors is a crucial step toward effective intervention. Methods: This study analyzed data from 463 adolescents (42.12% boys; mean age = 16.21 years, range 12–18) to explore the relationships between NSSI, parental psychological control, self-disgust, and resilience. Results: Multivariate logistic regression indicated that parental psychological control, self-disgust, and resilience were significantly associated with NSSI. Furthermore, in the chain mediation model, self-disgust and resilience significantly mediated the relationship between parental psychological control and NSSI. Conclusions: This study examines the relationships between parental psychological control, self-disgust, resilience and NSSI in adolescents, providing theoretical insights and practical implications for developing intervention and prevention strategies.
