Abstract

Occupational hearing loss can be prevented by enhancing noise-induced hearing loss-preventing behaviors. This research and development aimed to develop and study the effectiveness of a promoting behavior model for noise-induced hearing loss prevention from working employees in stone milling factories. Phase 1: Studying the behavior of using hearing protection devices among stone mill factory workers. Quantitative data were collected from a simple random sampling of 72 employees using a behavioral questionnaire. Qualitative data were gathered from five key informants, including human resources personnel and safety officers of the factory, through in-depth interviews, as well as from focus group discussions with 10 workers. Phase 2: Developing a promoting behavior model for noise-induced hearing loss prevention from working employees in a small sample group of 10 people from a stone milling factory. Phase 3: Implementing the model and evaluating its effectiveness. The sample was divided into an experimental group and a comparison group, with 36 participants in each group. The research instruments included the behavioral promotion model, a personal information questionnaire, a behavioral assessment questionnaire, a questionnaire on stages of behavior change, a process of behavior change questionnaire, and a behavior change stage evaluation form. The content validity was checked with the item consistency index of .99, and the Cronbach's alpha coefficient was found to be appropriate at .79-.94. The data were analyzed using descriptive statistics and t-tests. Research results found that Phase 1: The employees’ behavior in using hearing protection devices ranged from the pre-contemplation stage to the maintenance stage, with the highest proportion observed in the action to maintenance stage (38.89%). Phase 2: The behavioral promotion model consisted of five activities, including reinforcing for noise protection, identifying supportive factors, addressing behavioral conditions, managing the environment, and raising awareness about noise protection. Phase 3: After implementing the model, the experimental group showed a statistically significant increase in noise protection behavior compared to both the pre-intervention stage and the comparison group. The results in this study indicate that the promoting behavior model for noise-induced hearing loss prevention has an effect on preventing behaviors of working employees in stone milling factories.
