Reliability and convergent validity of the Job Components Inventory.

Further evidence is presented on the reliability and validity of the Job Components Inventory (JCI), a recently developed job analysis technique. The JCI covers the use of tools and equipment, physical and perceptual requirements, mathematical requirements, communication requirements, decision-making and responsibility requirements. Results of a study of 75 postmen and postwomen and seven supervisors are reported. Inter-rater reliability, supervisor-job incumbent agreement and inter-office agreement were all found to be high. This study indicates that the JCI can be used to analyse jobs other than low skill youth jobs for which it was originally developed [ABSTRACT FROM AUTHOR]
