Background and Objective: In many countries, the noise has been ranked among the important risk factors in the printing industries. The purpose of this study was to design a tool for assessing the level of knowledge, attitude, and practice of the printing industry workers in terms of hearing protection and determine its validity and reliability.
Materials and Methods: To design a questionnaire, 35 questions were provided as the first step. Content validity methods were utilized in order to evaluate the validity of the questionnaire. Moreover, Cronbach's alpha coefficient and test-retest methods were used to assess the reliability of the questionnaire. The data were analyzed using SPSS software (version 20).
Results: The obtained results showed that 10 items in terms of content validity were below the standard levels and should be removed from the questionnaire. In addition, in the reliability analysis of the questionnaire, Cronbach's alpha coefficients were reported as 0.884, 0.719, 0.832, and 0.727 for all four parts of knowledge, attitude, risk perception, and practice, respectively. The Spearman’s correlation coefficients with the results of 0.810, 0.861, 0.890, and 0.985, as well as Pearson correlation coefficients with the results of 0.912, 0.964, 0.866, and 0.991, were used for knowledge, attitude, risk perception, and practice, respectively, to analyze the test-retest method of the questionnaire.
Conclusion: Designing this questionnaire to investigate the knowledge, attitude, and practice of the printing industry workers regarding hearing protection can examine possible solutions to reduce the harmful effects of the noise on employed workers, which is recommended to be tested on a larger scale.
