Comparative reliability of numerically anchored versus job-task anchored rating scales

Abstract

Compared the effectiveness with which job-task anchored equal-appearing interval scales could be used in contrast with scales anchored only by simple numerical benchmarks. 2 groups of judges rated identical lists of job-task statements in terms of both types of scales. Ratings were made on 5 sensory/physical dimensions of job activities. The reliabilities of ratings for all scales were computed by an analysis of variance approach. In a test of statistical significance across all 5 scale dimensions, it was found that job-task anchored scales could generally be used with significantly greater reliability than simple numerically anchored scales.
