People's attitudes towards the use of quarantine in the Covid-19 pandemic in Iran: Validity and reliability study.

Background: The purpose of this study was first to translate (into Persian) and evaluate the psychometric properties of the attitudes towards the use of quarantine questionnaires (PAQ).

Methods: This methodological study was conducted on 1000 adults' participants in Iran, using convenience sampling. Based on permission from the developer of the scale, it was back-translated. Content validity, exploratory and confirmatory factor analyses were tested. Reliability of the questionnaire was evaluated with test-retest and internal consistency.

Results: The adequacy of the sample was acceptable because of the results of the Kaiser-Meyer-Olkin test (0.788), and Bartlett's test of sphericity revealed statistically significant results (P < .001). Exploratory factor analysis showed the 4-factor structure of the instrument. The reliability of the scale was 0.77 based on internal consistency. Also, the intra-class reliability of the scale was 0.9. The attitude of the maximum number of respondents towards quarantine is positive and they support a quarantine in the pandemic of COVID-19 in Iran.

Conclusions: Current study showed that the Persian version of attitudes towards the use of quarantine (PAQ) in the Iranian population including 17 items could be used as a valid and reliable instrument.
