Psychological determinants of behaviors leading to occupational injuries and diseases in agriculture : a literature overview.

Agriculture is one of the most hazardous occupational sectors, with a high prevalence of occupational injuries and work-related health problems. Most of these problems are caused by the interplay of human behavior and ergonomic factors and are thus preventable. Interventions to prevent occupational injuries and diseases among agricultural workers should aim to change risk behaviors and conditions by addressing specific behavioral determinants. To identify these factors, social cognitive models can be use that explain and predict health-related behavior. This study reviews the literature on the application of social cognitive models for the prevention of occupational injuries and diseases among agricultural workers. Studies are reviewed that apply the Health Belief Model, Theory of ReasonedAction, Theory of Planned Behavior, Transtheoretical Model of Change, or their subcomponents, to predict or change preventive behavior. Only a limited number of studies were found describing interventions that make use of these models, and those that do are often poorly documented with regard to the effect sizes and the explanatory or predictive value. It is concluded that the application of social cognitive models could significantly contribute to the effectiveness of preventive interventions in agriculture
