This article provides a commentary on 5 articles in the special section that marshal a substantial amount of information about 4 instruments for measuring work stress. The perspective is that of psychosocial epidemiology and highlights the differences between the environmental and the psychological traditions of studying stress and health. Several issues are addressed: (a) placing the 4 measures in a broader taxonomy of dimensions of work environment and evaluating the measures in that context, (b) discussing alternative strategies for measuring job strains, (c) analyzing some of the issues in the triviality debate, and (d) reconsidering a number of issues in the ongoing debate about "subjective" versus "objective" measurement approaches to work dimensions.
