“…Thus, a realist review is not just about the replication of outcomes, but understanding why those outcomes succeed or fail, the influences on those outcomes and the theory of change regarding the intervention (Pawson & Tilley, 2004). It is especially well suited to areas of complexity with variable outcomes (Berg & Nanavati, 2016; Wiese et al., 2017), exploration of mixed data (Kastner et al., 2011) and enables in‐depth analysis (Pawson et al., 2005). Realist reviews have an impact in a wide range of settings including health (Brennan et al, 2017), community mental health (Gee, Bhanbhro, Cook, & Killaspy, 2016), offender mental health (Pearson et al., 2015), domestic violence screening (O'Campo, Kirst, Tsamis, Chambers, & Ahmad, 2011) and advocacy (Rivas, Vigurs, Cameron, & Yeo, 2019).…”
