Question

A researcher has developed a measure of a person's ability to detect colors. He finds the measure is not related to a person's spelling ability, which is a different type of measure. This finding is an example of _____ validity.

Answer 1

The correct answer is discriminant

Discriminant validity tests the hypothesis that the measure in question is not unduly related to different constructs.

Content validity is concerned with whether the measure represents the  different aspects or facets of the phenomenon to be measured. Advises that for the  obtaining better content validity, the investigator should try to minimize the  possible criticisms about the aspect investigated through the review of the existing literature,  specifying, through a correct conceptual definition, what is, or is not, the object of  measure. In addition to these aspects, a broad list of items that represent  all relevant dimensions of the studied phenomenon and request an evaluation by judges and  experts who report on the scope of the content to be covered. There are no ways to guarantee  proof of content validity, considering that it depends on the degree of revision of the  researcher's value judgments, in addition to assuming that all  possible dimensions and contents of the concept, phenomenon or behavior investigate.
