Résumé : Abstract Background Transition-age youth (TAY) face heightened risk for the onset of psychiatric disorders and significant discontinuities when moving from child/adolescent to adult mental health services. Early intervention models, including clinical staging and transdiagnostic approaches, have been proposed to bridge this “transition gap” and improve continuity of care. Methods Following PRISMA 2020 guidelines, we conducted a systematic review registered in PROSPERO (CRD42024595896). Searches across five databases (PubMed, PsycINFO, Scopus, ProQuest, Cochrane) identified publications between 2013 and 2025 describing service models or early interventions for TAY. Eligible studies included quantitative, qualitative, and mixed methods designs. Methodological quality was appraised using design-specific tools (AMSTAR, NOS, Jadad, SANRA), with item-level scoring reported in Appendix 2. Results Twenty-six studies met inclusion criteria, spanning Europe, North America, and Australia. Observational and longitudinal designs predominated, with interventions embedded in youth-specific service models such as headspace (Australia), ReARMS (Italy), FREED (UK), and NAVIGATE (USA). Across contexts, key themes emerged: youth-friendly design and accessibility, autonomy and functional recovery, multidisciplinary integration, preventive focus, societal engagement, continuity of care, systemic challenges, and economic evaluation. Methodological quality was moderate to good. Integrated hubs and structured transition protocols consistently reduced disengagement, while preventive strategies targeting subthreshold symptoms demonstrated feasibility and early efficacy. However, variability in fidelity, systemic gaps (such as lack of national protocols, insufficient resources), and uneven accessibility remain barriers to scale-up. Conclusions Early intervention models for TAY show promise in improving continuity of care, reducing dropout, and supporting functional recovery. Youth-friendly, integrated, and preventive approaches are central to effective service design, yet systemic and policy-level reforms are required to ensure sustainability and equitable access. Future research should prioritize comparative evaluations, long-term outcomes, and strategies for embedding early intervention into routine practice across diverse health systems.
