Prediction and impact of maladaptive perfectionism on non-suicidal self-injury in adolescents: a study based on machine learning and structural equation modeling

These findings underscore the necessity for multi-target interventions that simultaneously address perfectionistic cognitions, impulsive tendencies, and regulatory skills in at-risk adolescents.
