Abstract: | In a sample of industrial job applicants, relationships among scores on an integrity test, a job knowledge measure, and maximal performance as assessed by a work sample measure were investigated. The observed correlation between the personality-based integrity test and maximal performance was .27, indicating that integrity tests can be predictive of maximal performance. Furthermore, integrity test scores correlated .14 with job knowledge and job knowledge scores had a validity of .36 for maximal performance. Theoretical implications for the maximal/typical performance distinction are discussed. |
