Preparing Teens to Stay Safe and Healthy on the Job: a Multilevel Evaluation of the Talking Safety Curriculum for Middle Schools and High Schools

摘要

US adolescents experience a higher rate of largely preventable job-related injuries compared with adults. Safety education is considered critical to the prevention of these incidents. This study evaluates the effectiveness of a foundational curriculum from the National Institute for Occupational Safety and Health (NIOSH), Talking Safety, to change adolescents' workplace safety and health knowledge, attitude, subjective norm, self-efficacy, and behavioral intention to engage in workplace safety actions. The study also examines the impact of teacher fidelity of curriculum implementation on student outcomes. A multilevel evaluation, based on a modified theory of planned behavior, was conducted in 2016 with 1748 eighth-graders in Miami-Dade, Florida. Post-intervention, students had statistically significant increases (p<.05) in mean scores across outcomes: workplace safety knowledge (34%), attitude (5%), subjective norm (7%), self-efficacy (7%), and behavioral intention (7%). Consistent with theory, gains in attitude (b=0.25, p<.001), subjective norm (b=0.07, p<.01), and self-efficacy (b=0.55, p<.001) were associated with gains in behavioral intention. Higher levels of implementation fidelity were associated with significant gains across outcome measures: knowledge (b=0.60, p<.001), attitude (b=0.08, p<.01), subjective norm (b=0.04, p<.001), self-efficacy (b=0.07, p<.01) and behavioral intention (b=0.07, p<.01). Findings demonstrate the effectiveness of Talking Safety, delivered with fidelity, at positively changing measured outcomes, and provide support for using this curriculum as an essential component of any school-based, injury prevention program for young workers.
