This study was aimed at exploring the possible roles of the cognitive attentional syndrome (CAS) and metacognitive beliefs in moderating the relationships between fear of coronavirus during the pandemic and health anxiety. Because some symptoms of health anxiety may overlap with symptoms of other anxiety disorders, we also tried to ascertain whether our hypothesized relations would be maintained when taking other anxiety disorder symptoms into account. We hypothesized that CAS strategies and meta-beliefs would play a role in the progression from fears of the coronavirus to coronavirus health anxiety. The method done was a cross-sectional study with n = 783 participants who completed questionnaires on fear of coronavirus, coronavirus-specific health anxiety, CAS, and symptoms of anxiety disorders. Fear of coronavirus and coronavirus health anxiety are correlated with medium effect size. CAS and metacognitive beliefs moderate the relationship between fear of coronavirus and symptoms of coronavirus-specific health anxiety. CAS predicts a unique part of health anxiety symptoms variance above symptoms of other anxiety disorders. The results of this cross-sectional study preclude causal inferences but tentatively suggest that CAS strategies may play a role in moderating the relationship between fear of coronavirus and coronavirus-related health anxiety. These relationships were obtained after controlling for variance shared with agoraphobia, social phobia, and general physical symptoms of anxiety.
