This integrative review explores adolescent motivation through 41 studies employing Interpretative Phenomenological Analysis (IPA). The findings reveal motivation as a multifaceted phenomenon shaped by emotional regulation, social support, autonomy, and identity development. Adolescents construct meaning by navigating social expectations, balancing authenticity with conformity, and seeking purpose through relationships. Key motivators include resilience, self-expression, and social belonging, highlighting the significance of interpersonal connections and supportive environments. The study underscores the value of IPA in capturing the nuanced, subjective dimensions of motivation, offering insights into how adolescents interpret challenges and construct identity. By integrating psychological, educational, and social perspectives, this review contributes to understanding how motivation fosters adolescent growth and development. These findings provide a foundation for interventions aimed at promoting well-being, agency, and meaningful engagement during adolescence, emphasizing the importance of relational and contextual factors in shaping motivational experiences.
