Ability and trait complex predictors of academic and job performance: A person-situation approach

A battery of cognitive ability, knowledge, and non-ability measures were administered to 105 college students enrolled in a cooperative school-work program and used to predict academic and job performance. Composite scores for each domain were derived from factor analyses of 11 measures of verbal, numerical, and spatial abilities, four measures of domain knowledge, and 27 measures of personality and motivational traits, vocational interests, and self-assessments. Both ability and non-ability trait composites were significant predictors of academic performance, but only the non-ability trait composites predicted job performance. Implications for the integrative assessment of individual differences and their predictive validities for performance in different active work contexts, as well as the importance of trait composites across contexts, are discussed.
