This study identifies job self-efficacy as a moderating variable that may determine whether job control contributes positively or negative to coping with work stressors. Data from two samples (health professionals and an occupationally diverse group) demonstrated similar interactions between demands, control, and self-efficacy predicting blood pressure. These results may reconcile the previous inconsistent and largely method-bound support for Karasek's job demands-control model and suggest that efforts to improve job self-efficacy may be as important to reducing the cardiovascular consequences of job stress as efforts to enhance control.

Results of a primary meta-analysis indicated a significant main effect of the organizational behavior modification (O.B. Mod.) approach on task performance (d. = .51; a 17 percent increase) and a significant treatment-by-study interaction. To account for within-group heterogeneity of effect sizes, we conducted a two-level theory-driven moderator analysis by partitioning the sample of studies first into manufacturing and service groups and then into seven classes of reinforcement interventions. Results indicated a stronger average effect of O.B. Mod. in manufacturing organizations, moderation by the type of contingent interventions, and "pairwise" differences among average effect sizes in both organizational types. The practical …
