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


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.

  1. The child labor provisions of the 1938 federal Fair Labor Standards Act (FLSA) prohibit the employment of minors in jobs and under conditions harmful to their health or well-being. These provisions restrict work hours for youth under age 16 and define hazardous occupations that the Secretary of Labor has determined to be too dangerous for minors under age 18 to perform. Certain businesses are exempt from the FLSA, and varying standards apply to agricultural and nonagricultural industries (Department of Labor, Wage, and Hour Division 2016).
