Construct Validity


Construct validity assesses whether the characteristic which a test is measuring is psychologically meaningful and consistent with how that construct is defined. Typically, the construct validity of a test is assessed by demonstrating that the test’s results correlate other major tests which measure similar constructs and do not correlate with tests that measure different constructs. (This is sometimes referred to as a test’s convergent and discriminant validity). Thus demonstrating that a test which measures fluid intelligence is more strongly correlated with an alternative measure of fluid intelligence than it is with a measure of crystallised intelligence, would be evidence of the measure’s construct validity.
