Construct validity primarily addresses:

Construct validity is a fundamental aspect of psychological testing that focuses on whether a test truly measures the theoretical construct it is intended to measure. This form of validity assesses the extent to which a test correlates with the underlying theoretical concepts and constructs related to the behaviors or attributes being measured. For instance, if a test is designed to measure anxiety, construct validity examines whether the test effectively captures the concept of anxiety according to existing psychological theories and frameworks.

Evaluating construct validity involves various methods, including examining convergent validity (how well the test correlates with measures of similar constructs) and divergent validity (ensuring the test does not correlate with measures of different constructs). This ensures that the test provides meaningful information about the construct it claims to assess, which is vital for the credibility and utility of psychological assessments.

The other options touch upon important aspects of test development but focus on different types of validity or measurement characteristics, such as criterion-related validity, reliability, and content validity, which do not directly address the core of what constitutes construct validity.
