OBJECTIVE: The causes of the long-term persistence of symptoms after a SARS-CoV-2 infection (i.e., post-COVID syndrome) remain elusive. Although previous research identified demographic and medical risk factors for the development of post-COVID, the present prospective study is the first to investigate the role of psychological factors.
METHODS: The interview and survey data of PCR positive participants (n = 137, 70.8% female) were assessed in the acute, subacute (3 months after symptom onset) and chronic phases (6 months after symptom onset) of COVID.
RESULTS: After controlling for medical (BMI, disease score) and demographic factors (gender, age), psychosomatic symptom burden (measured by the SSD-12) predicted higher odds and magnitude of COVID-related symptom impairment in the post-COVID phases. Fear of COVID related health consequences (measured by the FCV-19 scale) also predicted higher odds of reporting any COVID symptoms in the subacute and chronic phase, while it only predicted higher magnitude of COVID-related symptom impairment in the subacute phase. In subsequent exploratory analyses, we found that other psychological factors were associated with an overall increase (i.e., chronic stress and depression) or decrease (i.e., trait positive affect) in the odds and magnitude of COVID-related symptom impairment.
CONCLUSIONS: We conclude that psychological factors can fuel or temper the experience in post-COVID syndrome, opening new possibilities for psychological interventions.Registration: The study protocol was preregistered in the open science framework (https://osf.io/k9j7t).
