Evaluation Criteria – Validity & Reliability A. Validity – Accuracy of claims made in a research study 1. Internal validity (or causal validity) Accuracy of causal assertions of a study Do the relationships meet the criteria for causality? Are the connections/relationships among the variables defensibly argued? Are the claims supported by the evidence? Do the authors overstep their bounds of claims making? 2. External validity (or generalizability ) Accuracy of a study as it applies to other populations To what extent does the sample represent the larger population of interest? How generalizable are the results? How broadly can the results be applied to other populations? 3. Measurement validity Accuracy of the measures used Do the indicators accurately measure the concepts? B. Specific types of measurement validity 1. Face validity Measures appear to be appropriate “on their face” Do the measures make sense? Is a measure a plausible indicator at first glance? Are the measures consistent with other research?
