History and accuracy of validity generalization equations: A response to the Callender and Osburn reply.

In a continuation of the discussion between the present authors (Schmidt et al; see record 1983-07150-001) and J. C. Callender and H. G. Osburn (see record 1983-07128-001), it is contended that neither Callender and Osburn (see record 1981-27033-001) nor F. L. Schmidt and J. E. Hunter (see record 1978-11418-001) have invented a model that accounts for the impact of artifacts on validity coefficients; this accomplishment is attributed to Spearman and to Fisher. An example is presented showing that in realistic situations, the present authors' noninteractive equation is more accurate than the Callender and Osburn equation. The 4-artifact equations are shown to be superior in either validity generalization values characterizing the findings of the field and those used in a specific application.
