Results: < 0.01). 2) This study reveals that both negative and positive parenting styles serve as complete mediators in the relationship between impulsivity and NSSI behavior in adolescents, with distress tolerance as a significant factor. Conclusion: Impulsivity significantly influences NSSI behavior in adolescents through the mediation of parenting styles (both negative and positive) and distress tolerance.
