Development and Initial Validation of the COVID Stress Scales

Highlights

• •

  A large population-representative was surveyed to better understand COVID-19-related psychopathology.

• •

  We developed and validated the COVID Stress Scales, comprising 36 items on 5 scales.

• •

  The COVID Stress Scales offer promise for identifying people in need of pandemic-related mental health services.

Abstract

Research and clinical observations suggest that during times of pandemic many people exhibit stress- or anxiety-related psychopathology that include fear of becoming infected, fear of coming into contact with possibly contaminated objects or surfaces, fear of foreigners who might be carrying infection (i.e., disease-related xenophobia), fear of the socio-economic consequences of the pandemic, compulsive checking and reassurance-seeking regarding possible pandemic-related threats, and traumatic stress symptoms about the pandemic (e.g., nightmares, intrusive thoughts). We developed the 36-item COVID Stress Scales (CSS) to measure these features, as they pertain to COVID-19. The CSS were developed to better understand and assess COVID-19-related psychopathology. The scales were intentionally designed so they could be readily adapted for future pandemics. The CSS were developed and initially validated in population-representative samples from Canada (N = 3,479) and the United States (N = 3,375). A stable 5-factor solution was identified, corresponding to scales assessing COVID-related stress and anxiety symptoms: (1) Danger and contamination fears, (2) fears about economic consequences, (3) xenophobia, (4) compulsive checking, and (5) traumatic stress symptoms about COVID-19. The scales performed well on various indices of reliability and validity. The scales were intercorrelated, providing evidence of a COVID Stress Syndrome. The scales offer promise as tools for better understanding the psychopathology associated with COVID-19 and for identifying people in need of mental health services.
