“…Examples of evaluation designs include descriptive (e.g., case study, observational), correlational (e.g., cohort study, cross-sectional study), quasi-experimental (e.g., nonequivalent control groups design, regression discontinuity design), experimental (i.e., experiment with true randomization), and meta-analysis designs (Crano & Brewer, 2002). There has been a debate within the field of evaluation on what constitutes credible evidence (Donaldson, Christie, & Mark, 2009), with some evaluators arguing for RCTs as the "gold standard" (Petrosino, 2003;Scott-Little, Hamann, & Jurs, 2002) and others questioning the superiority of the RCT (Jacobs, 2004;McCall & Green, 2004). In particular, evaluators of youth programs have argued that RCTs may not always fit the program or the program's need for evaluation (McCall & Green, 2004).…”
