This study was a concurrent validation of a paper and pencil test battery used at a national trucking company. Forty-eight driver managers were rated by their immediate supervisors with the performance appraisal covering 12 dimensions of job behavior that was developed by the experimenter. The driver managers were also administered the Wesman Personnel Classification Test, the Watson-Glaser Critical Thinking Appraisal, and the California Psychological Inventory (CPI). A biographical information blank was also developed and validated. Most validity correlations were nonsignificant, with the exception of the Dominance scale r = .25 (p < .05), the Self-control scale r = -.25 (p < .05), the Communanlity scale r = .29 (p < .05), and the Flexibility scale r = -.39 (p < .05), with overall performance.

An independent pilot study suggested that the Retail Employment Inventory (REI) might be predictive of subjectively and objectively measured Over the Road (OTR) truck driver performance. The present validation study consisted of three parts. First, an examination of the relationship between REI scores and 11 objective, performance criteria revealed weak and non-significant correlations. Second, a comparison of subjective ratings and REI scores failed to replicate the findings of the pilot study. And third, to confirm that the task components of the OTR job were correctly identified in the pilot study, a second job analysis was performed. Possible reasons for the failure of the REI to predict OTR performance and directions for future research are discussed.
