Abstract: (2261 Views)
Background:The last strategy to protect workers' hearing against load noises is use of hearing protection devices. The efficiency of wearing headphone depends on its full time application. After education, we need to evaluate the efficiency of the conducted training course. One of the most important factors affecting a valid assessment is existence of an appropriate questionnaire
to evaluate the course properly. Methods: In order to standardize and investiagte the validity of the researcher-made questionnaire, 12 experts were asked to review it. To determine the questionnaire's validity, we used the face validity and content validity. In order to determine the quantitative content validity, we applied the content validity ratio (CVR) and content validity index (CVI). Then, reliability of the questionnaire was investigated by Alpha-Cronbach method. Results: We designed 30 questions as the questionaire's items, containing five demographic questions, 10 response questions, four content questions, four learning questions, four behavior evaluation questions, and seven questions about the outcomes. In experts' content evaluation, questions with CVR of higher than 0.56 were selected; while, the CVI of the remaining questions was 0.91. The overall reliability of the research tool was 0.83 using the internal consistency.Conclusion: This study provided a valid and reliable questionnaire for assessing the Kirkpatrick model. This questionnaire can be used as an appropriate tool to evaluate the training courses in accordance with the BASNEF model to increase the duration of using headphones by workers.
