This chapter looks at how to evaluate the quality and credibility of various types of quantitative research that might be included in a systematic review. Various factors that determine the quality and believability of a study will be presented, including, • assessing the study’s methods in terms of internal validity • examining factors associated with external validity and relevance; and • evaluating the credibility of the research and researcher in terms of possible biases that might influence the research design, analysis, or conclusions. The importance of transparency is highlighted.

Keywords:   critical appraisal, validity, reliability, credibility, efficacy, effectiveness, bias, treatment fidelity, effect size
