Professor Tyler believes that her measure of authoritarianism is valid after finding that it varies, as predicted by theory, with child rearing practices and voting behavior. Tyler is relying on a approach to validity.

Construct validity

Explanation:

Construct validity is the extent to which a research or test conducted measure what it claims to be measuring. This method of validity is established when researchers correlative their findings with other measures and then shows that the measures are associated in some way that is predictable by theory. A usual example of this is the measurement of the brain such as ability, emotion level, and/or intelligence level. Professor Tyler establishes a form of correlation between authoritarianism with voting behavior and child rearing. This shows construct validity.
