Teenagers experience hearing loss due to exposure to loud noises. This study aimed to explore the effect of educational intervention on hearing health literacy in boy students.

This research was conducted experimentally on high school boy students in Sanandaj, Iran, in 2021. Using multi-stage cluster sampling, eight schools with 40 students were randomly selected for each group. Data were collected using a researcher-made questionnaire with 42 questions assessing hearing-related health literacy. The intervention group received six sessions of 50-65 minutes of virtual education. Measures were administered prior to the intervention and at a two-week follow-up. The educational content was designed based on reliable sources and according to general, specific, and behavioral goals. Data were analyzed using SPSS version 23.

Before the intervention, there was no significant difference between the intervention and control groups in their average scores in the domains of ear and hearing-related health literacy. After the educational program, the ear and hearing-related health literacy scores of the intervention group significantly improved (p<0.05) as follows: mean comprehension and evaluation skills (from 43.8±18.6 to 81.3±10.6), communicating skills (from 49.8±8.9 to 66.3±6.9), and the ability to apply hearing health information (from 25.6±14.5 to 56.9±11.9).

Virtual education is effective in increasing ear and hearing-related health literacy among school students.

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. 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. 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. 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.
