Occupational Medicine: State of the Art Reviews; Chapter 6: Measurement of Psychosocial Workplace Exposure Variables Authors: Paul Landsbergis, Birgit Greiner, Niklas Krause, Joseph Schwartz, Tores Theorell
An important empirical and methodologic issue is the determination whether it is primarily the objective characteristics of jobs or an individual’s subjective perception and evaluation of them (or some combination of these) that is most predictive of changes in blood pressure and the development of cvd. This chapter describes three main approaches for measurement of job characteristics: self-report questionnaires (e.g., Job Content Questionnaire, Effort-Reward Imbalance questionnaire, Occupational Stress Index); imputation of job characteristics scores based on aggregate data (e.g. national job title averages); and external assessment (e.g. supervisor or coworker ratings, job analysis by expert observers). Use of multiple methods of assessment of job characteristics allows for triangulation. We review important research results, highlight advantages and limitations of each method and discuss some issues to be resolved through future research. We recommend multi-method strategies, for convergent validation, using as many of these approaches as possible.
