Recognizing adolescence as a critical period of social and emotional development, this investigation seeks to understand how distinct personality dimensions shape patterns of interpersonal interaction and conflict. Adopting a descriptive survey method, data were gathered from a randomly selected sample of 300 adolescent students using standardized instruments to assess both personality characteristics and conflict behaviors. Statistical analyses revealed significant correlations between core personality dimensions extraversion and Introversion and the frequency and nature of interpersonal conflicts. Adolescents with higher agreeableness and conscientiousness demonstrated lower conflict tendencies, whereas those exhibiting elevated neuroticism and lower emotional stability reported greater interpersonal discord. Gender, religion, and institutional type also emerged as significant moderating variables. The study emphasizes the educational implications of integrating conflict management and socio-emotional learning within school settings. It further suggests that promoting adaptive personality development can substantially reduce peer conflicts and enhance the psychosocial well-being of adolescents. These insights contribute to the broader understanding of personality behavior dynamics in adolescent populations, particularly within culturally diverse coastal communities. https://pubs.sciepub.com/ajap/14/1/1/ajap-14-1-1.pdf Personality traits Interpersonal conflict Adolescents and Emotional development
