Comparative Analysis of the Relative Validity for Subjective Time Rating Scales. Final Report.
Carpenter, James B.; And Others
Since the accuracy and validity of occupational data may vary according to the rating scale format employed, the first phase of the research described in the report employed hypothetical job descriptions from which accurate criterion data could be generated. The second phase of the research required developing an occupational survey instrument specifically designed for Air Force basic trainees. Criterion comparison (CRICOM) or error values were used with an analysis of variance design to determine the relative validities for subjective time rating scales. It was found that five-point relative scales were inferior to the other scales tested and that job incumbents could use scales of greater complexity than had previously been indicated in the literature. Results of the investigation indicate that a nine-point relative time spent scale yield the most accurate job description data from job incumbents using the Air Force developed occupational analysis methodology. Four appendixes covering 35 pages provide hypothetical job descriptions, time spent scales, and basic trainee job-task inventory. (Author/JR)
