Designing and Determination of Validity and Reliability of the Questionnaire Increasing the Duration of using the Hearing Protection Device by Workers based on BASNEF Model

After the engineering noise control and management control, the last way for controling noise is using the hearing protective devices, whose effectiveness depends on full-time use of it. Due to the lack of a standard questionnaire about increasing the duration of worker's usage of hearing protection devices based on BASNEF behavioral pattern, this study has been done to design and measures this tool psychometrically.
The initial questionnaire of this study is drawn out of the texts, similar articles, and questionnaires. Face Validity and Content validity are measured by Lavsheh method based on obtaining the view of experts’ panel and the reliability was done by cronbach's alpha coefficient by tile industry workers. All analyses were performed using 19 SPSS software.
Findings: face validity and content validity of 49 items were identified. In professional content evaluation, CVR of items up to 60% were selected and the CVI of the remaining questions became 0.79%. The reliability of each of below indexes was approved as follow: knowledge: 82%, attitude: 88%, abstract norms: 83%, enabling factors: 88%, behavioral intention: 96% function: 89% and the overall reliability of research tool were approved by measuring Cronbach's alpha as 88%.
Discussion & Conlusions: vThese results introduced good evidence about the validity and the reliability of measurement tools on BASNEF model in increasing duration of workers usage of hearing protection devices.
