3.2. Search methods for identification of studies

We will use the following strategies to identify completed and on‐going potential studies:

Database: Medline, PsycInfo, PsycExtra, Social Policy & Practice, Scopus, Repec, ERIC, Econlit, CASE Engagement database (EEP, UCL), and the US National Criminal Justice.

Supporting Information: Appendix A presents an example of the search strings used for publication databases and search engines, with terms for interventions, regions and methodologies.

In addition to searching electronic databases, we will also screen the bibliographies of included studies and existing reviews of wilderness intervention programmes for eligible studies. Issues of relevant journals will also be hand‐searched for any possibly includable studies. A full list of these journals in provided below, as well as a list of research organizations and websites that we will search for any relevant publications (Table 3).

List of journals

In addition, we will the search relevant websites listed in Table 4. We will snowball to other websites identified in these searches, systematically documenting each website searched (website, URL, date, any filters or search strings used and studies identified for screening).
