To that end, non-familial youth-adult relationships can powerfully impact youths\u2019 healthy development, mental health and well-being, and capacities for enacting change within home, school, and policy contexts. Agenda Gap is a youth mental health promotion programme based on this principle, in which adult facilitators support youth (aged 15\u201324) in co-exploring activities focused on mental health promotion and policy advocacy, while fostering supportive, trusting intergenerational relationships. This study presents a realist evaluation of Agenda Gap, drawing on realist qualitative interviews with youth participants (n = 18) and adult collaborators (n = 4). We constructed 15 initial programme theories in four theoretical areas that we subsequently explored via analysis of the realist interview data. The analysis used the middle-range theories of \u2018Third Space\u2019 and \u2018Third Place\u2019 to conceptualize and articulate how causal mechanisms were produced from the non-familial youth-adult relationships that are foundational to the programme. Results are presented across 10 context-mechanism-outcome (CMO) configurations in three sections: (1) Agenda Gap Facilitation Activates \u2018Third-Space\/Third-Place\u2019 Mechanisms; (2) Youth Enhance Personal Mental Health while also Supporting Mental Health of Friends and Family; (3) Youth Become Inspired and Informed to Act as Advocates and Policy Change Agents. Taken together, these findings provide insights into the important mechanisms of non-familial intergenerational trust building and demonstrate how a strengths-based conceptualization of youth mental health supports mental health maintenance, promotion, and advocacy for this population.<\/jats:p>","DOI":"10.1371\/journal.pmen.0000068","type":"journal-article","created":{"date-parts":[[2024,6,18]],"date-time":"2024-06-18T17:31:29Z","timestamp":1718731889000},"page":"e0000068","update-policy":"https:\/\/doi.org\/10.1371\/journal.pmen.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Identifying mechanisms of youth mental health promotion: A realist evaluation of the Agenda Gap programme"],"prefix":"10.1371","volume":"1","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6807-2957","authenticated-orcid":true,"given":"Justin","family":"Jagosh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7868-564X","authenticated-orcid":true,"given":"Corey","family":"McAuliffe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4664-8104","authenticated-orcid":true,"given":"Liza","family":"McGuinness","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7068-575X","authenticated-orcid":true,"given":"Trevor","family":"Goodyear","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rebecca","family":"Haines-Saah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8664-7344","authenticated-orcid":true,"given":"Zachary","family":"Daly","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tanya","family":"Halsall","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0048-7712","authenticated-orcid":true,"given":"Taylor G.","family":"Hill","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tyesa","family":"Kruz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joan","family":"Wandolo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tasneet","family":"Suri","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4649-2904","authenticated-orcid":true,"given":"Emily","family":"Jenkins","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2024,6,18]]},"reference":[{"key":"pmen.0000068.ref001","unstructured":"WHO.
