The Relationship between Interoceptive Sensitivity, Age, and COVID-19 Anxiety During the First National Lockdown in the United Kingdom
Interoception refers to the multidimensional representation of the internal states of the body, including their sensation, appraisal, integration, and regulation. COVID-19 targets internal respiratory, temperature and gastrointestinal systems, thus posing a primary threat to humans that causes anxiety. Here, we examined the relationship between the sensitivity to internal bodily states and COVID-19 anxiety during the first national lockdown in the UK, when uncertainties surrounding the virus were at their peak. Between April and July 2020, N=232 individuals across 6 age-categories completed questionnaires measuring interoceptive sensibility (BPQ-SF and MAIA-2) and COVID-19 anxiety (adapted STAI). Several significant relationships suggested that the heightened sensation and the noticing of bodily signals were associated with higher COVID-19 anxiety, while healthy appraisal, attention regulation, mind-body integration and trusting of bodily signals were related to lower levels of COVID-19 anxiety. Age was associated with changes across multiple interoceptive dimensions and was related to lower levels of COVID-19 anxiety. Regression results further revealed that, after controlling for trait anxiety, higher age significantly predicted lower levels of COVID-19 anxiety, and a lower score on the Not Worrying subscale significantly predicted higher levels of COVID-19 anxiety. Our results extend previous findings of an age-related decline in COVID-19 anxiety to suggest underlying biopsychological changes in interoception. Interoceptive sensitivity may significantly influence anxiety management and regulate adaptive behaviour in the presence of health threats. Age-related interoceptive changes therefore raise important questions about best-practice guidance for individuals across the lifespan in protecting their own and other’s physical and mental health during a pandemic.
