Question

What is meant by two methods of construct validity nd two methods of criterion vaidity?

Answer 1

Construct validty has two subtyles, namely, convergent and discriminant validity. Convergent validity refers to the extent to which two measures of the construct that are theoretically supposed to be related, are in fact related. On the other hand, discriminant validity measures the degree to which measurements that theoretically should be unrelated are, in fact, unrelated.

Criterion validity is also comprised of two subtypes, which are concurrent and predictive validity. Concurrent validity refers to a comparison between the measure and an outcome assessed at the same time. Whereas, predictive validity, on the other hand, compares the measure with an outcome assessed at a later time.
