Recent research has suggested that scores on measures of cognitive ability, measures of Conscientiousness, and interview scores are positively correlated with job performance. There remains, however, a question of incremental validity: To what extent do interviews predict above and beyond cognitive ability and Conscientiousness? This question was addressed in this paper by (a) conducting meta-analyses of the relationships among cognitive ability, Conscientiousness, and interviews, (b) combining these results with predictive validity results from previous meta-analyses to form a "meta-correlation matrix" representing the relationships among cognitive ability, Conscientiousness, interviews, and job performance, and (c) performing 9 hierarchical regressions to examine the incremental validity of 3 levels of structured interviews in best, actual, and worst case scenarios for prediction. Results suggested that interview scores contribute to the prediction of job performance over and above cognitive ability and Conscientiousness to the extent that they are structured, with scores from highly structured interviews contributing substantially to prediction. Directions for future research are discussed.
