Self-harm represents a significant mental health concern during adolescence and is associated with various psychological risk factors. The present exploratory probe examines the mediating role of perceived social support in the relationship between self-esteem and self-harm among adolescents. The sample consisted of 155 adolescents aged 13 to 18 years (M = 16.35, SD = 1.73). Self-esteem was measured using the Rosenberg Self-Esteem Scale (RSES), self-harm was assessed using a modified version of the Self-Harm Inventory (SHI), and perceived social support was measured using the Multidimensional Scale of Perceived Social Support (MSPSS). Data were analyzed using correlation analysis, linear regression, and mediation. More than half of the participants (53.5%) reported repeated engagement in self-harming behavior. Self-esteem was significantly negatively associated with self-harm (ρ = −0.508, p < 0.001) and explained approximately 22% of the variance in self-harm. Mediation analysis indicated that perceived social support partially mediated the relationship between self-esteem and self-harm. Lower self-esteem was associated with lower perceived social support, which in turn predicted higher levels of self-harm. The indirect effect was significant (B = −0.31, 95% BootCI (−0.63, −0.09)). These findings highlight the protective role of perceived social support and suggest that strengthening adolescents’ self-esteem and social support networks may contribute to the prevention of self-harm.
