“…Among the more prominent frameworks are the Exploration, Preparation, Implementation, Sustainment (EPIS) framework (Aarons et al, 2010); Getting to Outcomes (Wandersman et al, 2000); the Reach, Efficacy, Adoption, Implementation, and Maintenance framework (Glasgow et al, 1999); and the Active Implementation Frameworks (AIFs; Metz & Bartley, 2012). The way in which these have been utilized ranges from supporting the implementation of RSIs (Barbee et al, 2011; Metz et al, 2015; Pipkin et al, 2013), to structuring the investigation of such interventions (Gannon et al, 2019; Hickey et al, 2018; Moullin et al, 2019), or informing the development of theoretical concepts and models (Isaacs et al, 2017; Mason et al, 2014). While implementation frameworks differ in purpose, content, and form (Albers et al, 2017; Nilsen, 2015), they also have a number of aspects in common, among them the shared assumption that implementation occurs in stages—with two to four stages included in multiple frameworks (Albers et al, 2017).…”
