A previous study examined role stress in relation to work outcomes; in this study, we added job structuring antecedents to a model of role stress and examined the moderating effects of locus of control. Structural equation modeling was used to assess the plausibility of our conceptual model, which specified hypothesized linkages among teachers' perceptions of (a) mechanistic/organic job structuring, (b) role ambiguity, role conflict, and role overload, and (c) commitment, satisfaction, and intentions to leave the school. Respondents to survey questions designed to capture the above constructs included 177 teachers in seven moderately sized comprehensive high schools in Southern California. Results indicated that predicted patterns of relationships were partially moderated by locus of control. The study suggests ways to reduce role stress and enhance the work outcomes of teachers through identifying an appropriate job structure.
