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.
