Abstract
Background and Aim: Noise is the most common and also preventable harmful physical pollutant in the workplace in the world. Although the hearing protection devices are the last way to prevent hearing loss, most people do not use the equipment properly and consistently. The aim of this study was to determine the effect of theory-based training on the rate of using hearing protection devices in workers of autoparts factories in Qazvin Industrial Towns. Material and Methods: Using random sampling method, 120 workers from two autoparts factories in Kaspian and Alborz Industrial Towns were entered into this experimental study. Data collection tools included demographic questions and self-reporting questionnaire to measure TPB related constructs indirectly. The intervention program was composed of two 90 minute group discussion along with targeted educational booklet. Using SPSS version 20, data collected at different times were analyzed by chi-square, independent t-test and ANOVA. Results: After the intervention, we found increased mean scores for: attitude (from 36.0±17.3 to 64.5±22.8), subjective norms (from 28.5±10.7 to 46.8 ± 12.4), perceived behavioral control (from 41.8±19.3 to 72.1 ± 21.5), behavioral intention (from 3.6±3.1 to 7.5±3.8). Also use of hearing protection devices significantly increased in the experimental group (P<0.001). Conclusion: Educational intervention based on the theory of planned behavior led to increased use of hearing protection devices among workers. Designing educational programs based on the above mentioned theory in order to increase the use of personal protective equipment in workers is recommended.
