This study was approved in the second session of the Psychological Committee of the Islamic Azad University of Tehran’s province in March 2020. Results: The results illustrate that the GPQ has acceptable internal consistency with Cronbach’s alpha coefficient (a=0.67), reliability coefficients with split-half (0.72), and one-week test-retest (r=0.73); in addition, the GPQ demonstrate moderate convergent validity with contamination obsessions checklist of Y-BOCS (r=0.44) as a convergent coefficient; and finally, the exploratory factor analysis indicates three-factors of the GPQ. Conclusion: Based on these findings, the GPQ has acceptable and good psychometric properties; researchers can use the GPQ as a reliable and valid instrument for assessing the germophobia levels in epidemic and pandemic crises like COVID-19.
