Personality and Cognitive Ability as Predictors of Effective Performance at Work

Conclusions about the validity of cognitive ability and personality measures based on meta-analyses published mostly in the past decade are reviewed at the beginning of this article. Research on major issues in selection that affect the use and interpretation of validation data are then discussed. These major issues include the dimensionality of personality, the nature and magnitude of g in cognitive ability measures, conceptualizations of validity, the nature of the job performance domain, trade-offs between diversity and validity, reactions to selection procedures, faking on personality measures, mediator and moderator research on test–performance relationships, multilevel issues, Web-based testing, the situational framing of test stimuli, and the context in which selection occurs.
