Regardless of how construct validity is defined, there is no single best way to study it. In most cases, construct validity should be demonstrated from a number of perspectives. Hence, the more strategies used to demonstrate the validity of a test, the more confidence test users have in the construct validity of that test, but only if the evidence provided by those strategies is convincing.
In short, the construct validity of a test should be demonstrated by an accumulation of evidence. For example, taking the unified definition of construct validity, we could demonstrate it using content analysis, correlation coefficients, factor analysis, ANOVA studies demonstrating differences between differential groups or pretest-posttest intervention studies, factor analysis, multi-trait/multi-method studies, etc. Naturally, doing all of the above would be a tremendous amount of work, so the amount of work a group of test developers is willing to put into demonstrating the construct validity of their test is directly related to the number of such demonstrations they can provide. Smart test developers will stop when they feel they have provided a convincing set of validity arguments.
