29. Critically Evaluating Research Construct Validity External Validity Evaluate the adequacy of the operational definition. Is the operational definition sufficiently measuring the construct it claims to measure? Evaluate the extent that the results can generalize to other populations and settings. Can the results be replicated with other participants? Can the results be replicated in other settings? Internal Validity Evaluate the extent that it was the independent variable that caused the changes or differences in the dependent variable. Are there alternative explanations (confounds)?
