Occupational Exposure Risk for Swine Workers in Confined Housing Facilities.

In an effort to change unsafe tractor operating behaviors among Appalachian youth resulting from practices and habits learned through a socialization process (termed an "apprenticeship of observation"), this study implemented a four-part intervention in high school agricultural education classes that included implementation of a cost-effective rollover protective structure (CROPS) curriculum. The curriculum included farm safety information, specific NIOSH plans for CROPS construction, and procedures for CROPS installation on unprotected tractors. In this exploratory study, pre- and post-assessments were conducted using theory of planned behavior (TPB) constructs to measure changes in four factors that influence changes in learner behavior: learner attitude, perceived social norms, behavioral control, and perceived behavioral intention.
