Convergent validity in the behavioral sciences refers to the degree to which two measures that theoretically should be related, are in fact related. Convergent validity, along with discriminant validity, is a subtype of construct validity. Convergent validity can be established if two similar constructs correspond with one another, while discriminant validity applies to two dissimilar constructs that are easily differentiated.
Evaluation / application
To assess the extent of convergent validity, a test of a construct is correlated with other tests designed to measure theoretically similar constructs. For instance, to assess the convergent validity of a test of mathematics skills, the scores on the test are correlated with scores on other tests that are also designed to measure basic mathematics ability. High correlations between the test scores would be evidence of convergent validity. ==See also==
