All the analyses were performed in SPSS software version 24 with a significance level of 5%.   Results: 30% (6 people) of the subjects were, 70% (40 people) of whom had   less than 15 years of work experience. Four items of the questionnaire were removed based on the minimum Lawshe's CVR values, as their CVR was less than 0.62. Finally, the (KR20) coefficient, scale-level CVI, and ICC were estimated at 0.827, 0.98, and 0.52, respectively. Conclusion:  The validity and reliability of the questionnaire were confirmed; therefore, this Persian version of 25-item scale is proposed as a suitable and effective tool for COVID-19 prevention measures in Persian language
