Explanation
Validity refers to the accuracy and appropriateness of a research method, measurement, or study. A valid measurement truly captures the concept or phenomenon that researchers intend to examine.
Different forms of validity can be distinguished, including construct validity, internal validity, external validity, and ecological validity. Researchers seek to ensure that their findings are meaningful, credible, and scientifically sound.
In sociology and criminology, validity is particularly important when measuring abstract concepts such as deviance, fear of crime, social inequality, or attitudes toward punishment.
Theoretical Reference
Validity is a core principle of empirical social research and scientific methodology. Quantitative and qualitative traditions both address questions of validity, although they often apply different criteria for evaluating research quality and interpretation.
