“…Such analyses are sometimes carried out to supplement the initial findings from RCTs by describing for whom or under what conditions under which the innovation “worked,” to uncover the best strategies for supporting optimal implementation, or to discover the influence of variation in context on implementation in a scale-up or sustainability study. These mostly exploratory analyses generally fall into two categories: those that examine short-term or immediate influences on implementation (e.g., Kurki, Boyle, & Aladjem, 2006; McCormick, Steckler, & McLeroy, 1995; Penuel, Fishman, Yamaguchi, & Gallagher, 2007) and those that examine long-term influences supporting sustained implementation over time (e.g., Clements et al, 2015; Lieber et al, 2010; McIntosh et al, 2013). Notably, in addition to quantitative studies, there are numerous examples of qualitative and mixed-methods studies that examine the influence of supportive or inhibiting factors on innovation implementation and sustainability (e.g., Billing, Sherry, & Havelock, 2005; Century & Levy, 2002; Lieber et al, 2009; Rijsdijk et al, 2014).…”
