Construct validity is concerned with whether a test measures the psychological construct it claims to measure. Therefore, collecting construct validity evidence would be the best way to determine if a test measures an underlying psychological construct. Content validity (#A) is concerned with whether a test adequately covers all aspects of the construct being measured. Predictive validity (#C) is concerned with whether a test predicts future outcomes related to the construct being measured. Criterion validity (#D) is concerned with whether a test correlates with established criteria related to the construct being measured. While these types of validity evidence are important, they do not specifically address whether a test measures the underlying psychological construct.
