Unpacking the Psychosocial Triad: How Adolescent Self-Expression Mediates Personality Development, Educational Aspirations, and Peer Group Dynamics

Abstract

Adolescent development is a critical transitional period shaped by the intersection of personal identity formation, peer socialization, and future-oriented academic expectations. While individual psychological components are well-documented, limited empirical research has evaluated how communicative competence mediates the structural relationship among personality development, educational aspirations, and peer group dynamics. This study empirically investigates the mediating role of adolescent self-expression in relation to personality development, educational aspirations, and peer group relationships among secondary school students. Adopting a quantitative positivist paradigm and a descriptive correlational research design, a stratified random sample of N = 600 secondary school students (Classes IX to X; aged 13 to 19 years; 69.17% male, 30.83% female; 59.83% urban, 40.17% rural) was evaluated across designated institutional locations in West Bengal. Primary data were collected using a bilingual psychometric instrument incorporating a 5-point Likert scale, comprising a Personal Data Sheet, the Self-Expression Scale, the Personality Inventory, the Educational Aspiration Scale, and the Peer Group Relationship Scale. Descriptive statistics (Mean and Standard Deviation) and inferential statistics (Pearson's Product-Moment Correlation) were utilized to test hypotheses at an alpha significance level of p < 0.01. Bivariate correlation analyses revealed that self-expression maintains positive and statistically significant relationships with personality development (r = 0.248, p < 0.001, M = 81.20, SD = 9.88 for self-expression; M = 77.93, SD = 11.98 for personality), educational aspirations (r = 0.211, p < 0.001, M = 84.82, SD = 12.47), and peer group relationships (r = 0.212, p < 0.001, M = 76.91, SD = 16.84). These empirical findings confirm that communicative competence functions as an active psychological mechanism supporting ego maturity, academic ambition, and healthy social integration. The findings validate the biopsychosocial framework of the adolescent psychosocial triad, demonstrating that fostering supportive communication climates enhances personality adjustment, academic motivation, and overall psychosocial wellbeing. These insights provide an empirical foundation for educators and policymakers to design targeted institutional interventions within secondary educational environments.
