Methodological issues for intervention research in occupational health and safety.
This article presents a brief summary of the nature and extent of intervention research being conducted in the area of occupational safety and health. Articles were classified either as engineering, administrative, or behavioral, according to the type(s) of interventions that were evaluated. Findings suggest that many of the intervention studies conducted lacked a theoretical basis, used small samples, and tested interventions lacking the intensity to cause the desired change. Most study designs were either nonexperimental or quasi-experimental. Recommendations for conducting future research are presented.
