Examining the criterion related validity of the general ability measure for adults: A two sample investigation

Abstract

Across two employee samples (N=262 and 265) the authors examined the criterion-related validity of the General Ability Measure for Adults (GAMA), a brief nonverbal measure of cognitive ability. Results suggested that GAMA predicted job performance in both samples (uncorrected rs ranged from .27 to .50). No evidence was found for differential prediction across gender and age. These results highlight the usefulness of nonverbal cognitive ability tests in selection contexts. © 2010 Blackwell Publishing Ltd.
