Abstract

Background and Purpose: COVID-19’s proliferation worldwide remains a significant threat to public health; therefore, the assessment and measurement of people’s intentions concerning the prevention of this threat can contribute to the development of suitable educational messages that promote preventive behaviors. This study aimed to develop a questionnaire to determine the factors affecting person’ intention of COVID-19 prevention (FAPI-COP).

Materials and Methods: This descriptive study was conducted on the people living in Mazandaran Province in 2020. The questionnaire was designed via literature review, focus group discussions, and interview with experts. A total of 10 specialists were selected to determine the content validity scores and 10 Mazandarani laypeople used to determine the reliability of the questionnaire. Finally, content validity index (CVI) and content validity ratio (CVR) were calculated by using Cronbach’s alpha and intraclass correlation coefficient (ICC) in SPSS, version 24.00.

Results: The first questionnaire consisted of 51 questions, and after evaluating validity and reliability, 36 questions were obtained. The content validity index of the questionnaire was 0.91, the content validity ratio 0.69, the Cronbach's alpha coefficient 0.78, and the internal correlation coefficient (ICC) 0.95 with the confidence interval of 0.80-0.99.

Conclusion: The results of the study showed that the present questionnaire had acceptable levels of reliability and validity, making it a useful tool in determining the factors affecting intention of COVID-19 prevention by people.
