Objective: To validate a hearing conservation program (HCP) questionnaire based on the health belief model and stages of change model (or transtheoretical model).Material and Methods: The perception levels of 145 workers who voluntarily participated at 2 companies were determined using this HCP questionnaire from April 2014 to September 2015. Exploratory factor analysis was performed to justify the final questionnaire.Results: The final questionnaire had 24 items with 5 components: risk acceptance (8 items), perceived barriers (3 items), perceived benefits (5 items), role model (4 items), and the stages of change (4 items). Cronbach’s alpha coefficients of each component were 0.75, 0.64, 0.84, 0.85, 0.71, and the total Cronbach’s alpha coefficient of this questionnaire was 0.78. Workers in the factory who promoted continuous safety activities of HCP had a better score in all dimensions than those workers in the factory who did not.Conclusion: This questionnaire of 5 components was a well validated, predictable, and positive instrument for the HCP situation in manufacturing.
