This study aims to investigate the psychological dimensions of cognitive, emotional, and behavioral aspects that arise as a consequence of COVID-19-related quarantines. Moreover, considering demographic factors, we hypothesize that these quarantines may influence the cognitive, emotional, and behavioral aspects. We performed a descriptive crosssectional design using an online survey (Google Forms) to gather data from a cohort of Jordanian participants during the period of quarantines spanning from March 21st to May 31st, 2020. The study sample contained (1577) individuals aged between 15 and 65 years. The survey employed a validated Arabic psychological scale. Findings revealed that the cognitive aspect experienced the most effect during the quarantine period in Jordan, followed by the behavioral aspect. Differences were observed in emotional and behavioral aspects across age group and marital status. Furthermore, age and gender appeared as predictors of psychological dimensions. Cognitive aspect was the most aspect affected by quarantine periods. We propose the implementation of psychological awareness programs by governmental organizations to address the cognitive, emotional, and behavioral concerns that may arise during pandemics.
