Criterion validity, construct validity, and factor analysis: An introductory overview.

ABSTRACT: This is the fourth and last article in the series on translation, adaptation, or development of a rating scale and its psychometric testing. The focus of this article is on criterion validity, construct validity, and factor analysis. Validity refers to whether the tool measures "what it purports to measure." Content validity, criterion validity, and construct validity are the different types of validity. Content validity was previously discussed in this series. Criterion validity assesses how a new scale correlates with a criterion or "gold standard."
