“…Of the included studies, one was a randomized controlled trial (Hardy, 2003), and one was a quasi-experimental study (Howard, 2005). The other eight were pretest/posttest studies (Gross, Miltenberger, Knudson, Bosch, & Breitwieser, 2007; Hanratty, Miltengerger, & Florentino, 2016; Liller et al, 2003), posttest only with a control group (Gatheridge et al, 2004; Himle et al, 2004; Kelso, Miltenberger, Waters, Egemo-Helm, & Bagne, 2007; Miltenberger et al, 2009), or posttest only with no control (Jostad, Miltenberger, Kelso, & Knudson, 2008).…”
