The Coronavirus Reassurance-Seeking Behaviors Scale (CRBS) is a self-report measure of reassurance-seeking behaviors associated with concerns over coronavirus infection. Although it is generally considered helpful to be mindful of signs of COVID-19, excessive reassurance seeking may lead to negative consequences, such as increased anxiety, for some people. Therefore, the CRBS was developed to help clinicians and researchers measure the frequency that a person engages in coronavirus-related, reassurance-seeking behavior.
