Relationship Between Honesty, Ability, and Personality Tests and Job Performance

The relationship between honesty, mental ability, and personality and job performance was investigated. Subjects were 68 female and 9 male credit union tellers. The instruments used were the: Stanton Survey; Profile; credit union’s own performance appraisal instrument. Scores for Mental Ability, Honesty, and Personality were regressed on job performance ratings. Results indicated that honesty did not add significantly to the prediction of job performance over and above either mental ability (change in R$sp2$ =.01, F(1,74) =.85, p $>$.05) or personality (change in R$sp2$ =.03, F(1,65) = 2.31, p $>$.05). The combination of all three tests was no better at predicting job performance ratings than mental ability or honesty alone (change in R$sp2$ for all three versus Mental Ability =.12, F(11,64) =.90, p $>$.05; change in R$sp2$ for all three tests versus Honesty =.19, F(11,64) = 1.40, p $>$.05). However, the combination of all three tests predicted job performance to a greater extent than Personality alone (change in R$sp2$ for all three tests versus Personality =.15, F(2,64) = 5.94, p $<$.01).
