<p>School-aged children are increasingly spending less time outdoors and more time on screens. Research demonstrates that increased childhood exposure to nature is associated with better mental health outcomes, improvements in cognitive functioning and creativity. Outdoor education programs (OEPs) generally involve a remote nature-based setting and outdoor activities such as hiking, sailing, and rock climbing. These programs can vary considerably in length, from overnight stays to year-long residential experiences. This PRISMA-guided scoping review examined wellbeing outcomes of OEP participation among primary and secondary students. Wellbeing outcomes were explored using the PERMA framework, which comprises of Positive Emotion, Engagement, Relationships, Meaning and Accomplishment. A secondary aim was to explore whether program duration influences wellbeing outcomes over time. Twenty studies met inclusion criteria and the majority of results (80%) demonstrated that OEPs positively impacted wellbeing factors including participants’ relationships, personal growth, self-efficacy and sense of achievement. These positive impacts were found across all OEP durations from short-term to extended programs. Wellbeing impacts were present immediately following OEP completion and were sometimes sustained weeks, months and years after participation. A minority of study results (20%) found mixed or no significant wellbeing changes when comparing pre- and post-program data or qualitative interviews. Limitations are discussed including study design heterogeneity and study quality. Overall, findings from this scoping review support greater integration of OEPs into school curricula to enhance student wellbeing and shape their identities long after they have left camp.</p>
