Validity generalization in the context of situational models.

Abstract

A primary objective of validity generalization analysis is to decompose the between-situation variance in validities into (a) variance attributable to between-situation differences in statistical artifacts and (b) variance attributable to between-situation differences in (unidentified) situational moderators. This process is based on the assumption that the effects of statistical artifacts on validities are independent of the effects of situational moderators on validities. The present article seeks to question the independence assumption by theoretically integrating situational variables into the validity generalization estimation process.
