Identifying mechanisms of youth mental health promotion: A realist evaluation of the Agenda Gap programme.

This study presents a realist evaluation of Agenda Gap, drawing on realist qualitative interviews with youth participants (n = 18) and adult collaborators (n = 4). The analysis used the middle-range theories of ‘Third Space’ and ‘Third Place’ to conceptualize how causal mechanisms were produced from the non-familial youth-adult relationships that are foundational to the programme.
