Studies in job evaluation. 5. An analysis of the Factor Comparison System as it functions in a paper mill

Abstract

"Factor Comparison System job evaluation data from a paper mill were subjected to the Thurstone Factor Analysis technique following the intercorrelation of points awarded on each of the job elements and the total. Rotation was accomplished by the graphical method. The Wherry-Doolittle shrinkage selection method was used to select three of the job elements for an abbreviated scale." These were: Skill Requirements, Working Conditions, and Mental Requirements; when combined, these correlated .99 with the original scale. The evaluation system effected judgments on 2 principal axes. One of these, termed Skill Demands, accounted for 98% of the final variation in job rates, while the other—Job Characteristics—was responsible for only 2%. The abbreviated scale is considered as usable as the original scale. (See also 18: 3249; 19: 3127; 20: 3283; 21: 237.) (PsycInfo Database Record (c) 2025 APA, all rights reserved)
