Convergent, discriminant, and incremental validity of competing measures of emotional intelligence.

Campbell and Fiske (1959) introduced the concept of discriminant validity within their discussion on evaluating test validity.

A successful evaluation of discriminant validity shows that a test of a concept is not highly correlated with other tests designed to measure theoretically different concepts.

Therefore, we cannot claim discriminant validity between them.

They may want to show discriminant validity with a scale measuring Self-esteem.

Convergent validity, along with discriminant validity, is a subtype of construct validity.

Interestingly, their results indicate the lack of discriminant validity among the three factors of OI.

Maximizing the discriminant validity of phallometric assessment data.

Again, a series of studies suggest that the three-factor model displayed convergent and discriminant validity.

Evaluation of discriminant (divergent) validity - The construct being measured by a test should not correlate highly with different constructs.
