This comprehensive review examines the empirical evidence on the transformative impact of prosocial and altruistic behaviours on relationship quality and self-esteem growth in adolescents. By synthesizing findings from over several studies, this paper reveals that engaging in voluntary actions benefiting others (Prosocial behaviour) and selfless concern for others' welfare (Altruistic behaviour) significantly enhances adolescent relationships, fostering stronger social connections, empathy, and cooperation. Moreover, these behaviours contribute to self-esteem growth by promoting a sense of purpose, competence, and positive self-image. The review explores theoretical frameworks, including social learning theory and self-determination theory, and contextual factors influencing prosocial and altruistic development, such as family, school, and community environments. Key findings indicate that prosocial behaviour predicts improved peer relationships, social acceptance, and reduced loneliness, while altruistic behaviour enhances self-esteem, life satisfaction, and psychological well-being. Parental and teacher support emerge as critical facilitators of prosocial and altruistic behaviours. School-based interventions promoting prosocial behaviour demonstrate positive effects on relationship quality and self-esteem. This review underscores the importance of integrating prosocial and altruistic behaviours into adolescent development programs, highlighting implications for educators, and mental health professionals. By elucidating the benefits of prosocial and altruistic behaviours for adolescent relationship quality and self-esteem growth, this paper informs evidence-based strategies to support positive youth development and identifies avenues for future research, including longitudinal studies and culturally sensitive interventions.
