Psychological Predictors of Deviant Behaviour among In-School Adolescents in Iwo, Osun State, Nigeria

Abstract

Abstract

Deviant behaviour among adolescents is influenced by a complex interplay of psychological and social factors. This study examined the psychological predictors of deviant behaviour among 187 in-school adolescents in Iwo, Osun State, focusing on childhood trauma, peer influence, and self-esteem. Data were collected using standardized instruments assessing trauma exposure, peer influence susceptibility, self-esteem, and engagement in deviant acts. Correlation analysis indicated that childhood trauma (r = .57, p < 0.01) and peer influence (r = .53, p < 0.01) were positively associated with deviant behaviour, while self-esteem was negatively associated (r = -.49, p < 0.01). Multiple regression results revealed that these predictors jointly accounted for 48% of the variance in deviant behaviour (R² = .48, F(3,183) = 57.32, p < .001). Childhood trauma emerged as the strongest predictor (β = 0.39), followed by peer influence (β = 0.34), with self-esteem serving as a moderate protective factor (β = -0.28). The findings underscore the significant roles of early adverse experiences, peer dynamics, and individual psychological resources in shaping adolescent behaviour. Interventions that enhance self-esteem, provide social support, and address the consequences of childhood trauma are recommended to mitigate deviant behaviour among adolescents.
