To determine whether a test measures some underlying psychological construct, the most appropriate type of validity evidence to collect would be construct validity evidence. Construct validity is defined as the degree to which a test assesses the specific psychological construct it purports to measure. It is typically established by demonstrating associations with other relevant measures, showing convergence with conceptually related constructs, and distinguishing the construct from unrelated constructs. Content validity refers to the degree to which a test measures a representative sample of the domain it is intended to measure, predictive validity refers to the degree to which a test predicts future performance on a criterion measure, and concurrent validity refers to the degree to which a test agrees with existing measures of the same construct administered at the same time. While these other types of validity evidence can be informative, construct validity is most directly relevant to assessing whether a test is measuring the psychological construct of interest.
