“…The studies (Table 1) offered summer reading programs to children at risk or at some risk of reading difficulties (Beach et al, 2018;Christodoulou et al 2017;Rafferty, 2012;Siddiqui et al, 2014;Zeng et al, 2016;Zvoch & Stevens, 2013) and behavioral problems (Hart et al, 2016;Rafferty, 2012;Zeng et al, 2016) or to low-income children (Beach et al, 2018;Gettinger & Stoiber, 2018;Hart et al, 2016;McCormick et al, 2021;Nicholson & Tiru, 2019;Pears et al, 2014;Siddiqui et al, 2014;Sinatra & Eschenauer, 2012;Xu & de Arment, 2017;Zvoch & Robertson, 2017). The programs ranged from 2 weeks to 8 weeks over a period of several years (i.e., longitudinal studies; Kraft & Monti-Nussbaum, 2017) or just for one summer and were administered to children in different grades (Christodoulou et al 2017;Gettinger & Stoiber, 2018;Nicholson & Tiru, 2019;Rafferty, 2012;Siddiqui et al, 2014;Sinatra & Eschenauer, 2012;White et al, 2014;Zeng et al, 2016;Zvoch & Stevens, 2013), or were used to prepare for the coming grade (Beach et al, 2018;Hart et al, 2016;McCormick et al, 2021;Pears et al, 2014;Zvoch & Robertson, 2017;Xu & de Arment, 2017). Thus, we have structured the narrative description of these studies according to their experimental design.…”
