“…Firstly, a large proportion of existing reviews are conceptual and descriptive, with a limited focus to specific migrant issues, populations, or settings (Barrie & Mendes, 2011;Botfield, Newman, & Zwi, 2016;Connor, Page Layne, & Ellis Hilb, 2014;Demazure, Gaultier, & Pinsault, 2018;Ehntholt & Yule, 2006;Nocon, Eberle-Sejari, Unterhitzenberger, & Rosner, 2017;Streitwieser, Loo, Ohorodnik, & Jeong, 2018;Sullivan & Simonson, 2016;Tyrer & Fazel, 2014;Vossoughi, Jackson, Gusler, & Stone, 2018). Secondly, there are insufficient numbers of rigorously designed and executed systematic reviews that also include a transparently reported study quality appraisal (Borsch et al, 2018;Botfield, Newman, Lenette, Albury, & Zwi, 2018;d'Abreu, Castro-Olivo, & Ura, 2019;Nakeyar, Esses, & Reid, 2018;Van Os, Zijlstra, Knorth, Post, & Kalverboer, 2018). Thirdly, none of the reviews specifically examine whether interventions were co-designed and therefore incorporated stakeholder's views in the design of the study.…”
