Mapping the Relationship between Health-related Beliefs, Fear, Avoidance, and Depression: Lessons from the Pandemic...

The COVID-19 pandemic brought a mental health crisis, with depression symptoms increasing nearly three-fold compared to pre-pandemic levels. To explain this surge and to outline related novel treatment targets for post-pandemic psychiatric interventions, the current study examined cognitive, emotional, and behavioral predictors of depression (in the context of the recent pandemic). Participants completed measures assessing perceived danger, perceived infectiousness, and fear of the coronavirus (COVID-19). Participants also reported symptoms of depression and behavioral tendencies: pandemic-related compulsive checking, cleaning, and avoidance (of activities, situations, places, and people). A multiple mediation model revealed that the relationship between perceived infectiousness of the virus and depression was atemporally mediated by fear of the virus and pandemic-related avoidance of activities, situations, places, and people. Furthermore, avoidance played a uniquely important role in the mediation model. First, it directly mediated the relationship between perceived infectiousness and depression, even when omitting fear from the model. Second, avoidance was a discriminant predictor of depression, as neither pandemic-related checking and reassurance-seeking nor cleaning behavior mediated the relationship between cognition and depressive symptoms. Clinical implications are discussed, including how addressing the relationship between anxiety about viral infections and depression can prospectively increase treatment success as we move beyond the pandemic.
