“…To balance the emphasis on internal and external validity, Glasgow et al (1999) designed an evaluation framework that expands assessments of interventions beyond efficacy. This Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework has demonstrated utility in evaluating internal and external validity indicators for a number of health behaviour interventions (e.g., nutrition and PA) (Aittasalo et al, 2006;DerAnanian et al, 2012;Dunton et al, 2009;Jenkinson et al, 2012;Nigg et al, 2012), and has been used in reviews of literature to demonstrate the degree to which researchers reported on external validity issues (Akers et al, 2010;Allen et al, 2011;Antikainen and Ellis, 2011;Dzewaltowski et al, 2004;Glasgow et al, 2004;White et al, 2009).…”
