ABSTRACT: Educational achievement gaps persist globally, with some ethnic minority and socioeconomically disadvantaged students consistently underperforming. Self-affirmation interventions, brief value-reflection exercises, have shown promise for reducing identity threats, yet recent replications yield mixed results, necessitating systematic evaluation of when and how these interventions might work. This structured review evaluates self-affirmation interventions for adolescents aged 11 - 15, addressing: 1) overall effectiveness; 2) underlying mechanisms; 3) moderating factors; 4) optimal conditions; and 5) implications for practice. Following PRISMA 2020 guidelines, we systematically searched multiple databases for studies published 1990-2025, focusing on interventions for students aged 11 - 15 with educational or psychological outcomes. The synthesis of eighteen studies involving 81 to 4002 participants across six countries revealed that twelve studies (67%) reported positive effects on academic performance, while four found null effects and two showed negative effects in specific subgroups. Notably, effectiveness was strongly context-dependent: interventions succeeded when moderate stereotype threat existed alongside supportive environments, multi-session implementation, and among moderately performing students. The evidence supports decoupling mechanisms whereby affirmation disrupts links between poor performance and diminished belonging, with effects proving stronger for academic outcomes and belonging than psychological distress. These findings indicate that self-affirmation interventions are context-sensitive tools requiring alignment of meaningful threat, environmental support, quality implementation, and student receptivity. Importantly, effectiveness cannot be assumed from delivery alone, and psychological interventions must complement, not replace, structural reforms. Future research should prioritize mediation testing, cultural adaptation, and implementation fidelity to advance both theoretical understanding and practical application.
