Single-group validity: Fact or fallacy?

Abstract

13 studies, including 1,291 white and 1,308 black Ss, were examined with regard to single-group validity. Each study employed approximately equal sample sizes for both the black and the white samples. Results indicate that the significance of validity coefficients was independent of racial group membership for the entire sample of studies (p > .30). Further, the significance of the validity coefficients remained independent of racial group membership for studies employing only subjective criteria (p > .25) and for studies employing only objective criteria (p > .50). Findings provide clear and direct confirmation of the results of F. L. Schmidt et al (see record 1974-10042-001 ) demonstrating the nonexistence of true single-group validity.
