Long-term childhood cancer survivors are at risk for frailty and have significant health-related issues in adulthood. Various health promotion interventions have been proposed to enhance quality of life including wilderness therapy, which applies the impact of nature on health in a therapeutic context. Previous studies have described positive outcomes linked with various wilderness-related therapies for cancer survivors. However, there is no clarity on the role these therapies play in childhood cancer. The current scoping review aims to systematically map the concept, content and outcome of wilderness therapy for childhood cancer survivors.This review will be guided by the Joanna Briggs Institute Reviewers' manual for scoping reviews. A systematic literature search using medical subject headings (MeSH) and text words related to wilderness therapy and childhood cancer survivors will be performed in EMBASE, ERIC, Medline, Psycinfo, CINAHL, Scopus, Web of Science, SPORTDiscus and Svemed+, Sociological Abstracts, supplemented by grey literature searches. Eligible quantitative and qualitative studies will be screened, included, assessed for quality and extracted for data by two reviewers independently. Results will be described in a narrative style, reported in extraction tables and diagrams, and where appropriate in themes and text.This study describes a protocol for a scoping review that will undertake secondary analysis of data already published in literature and is therefore exempt from medical ethical review. The scoping review will inform understanding of the benefits and risks of wilderness therapy for childhood cancer survivors, their families, practitioners, clinicians and researchers, and will help elucidate the steps necessary for building its evidence base going forward. Results will be published in a peer-reviewed scientific journal.
