Testing the Common-Sense Model, this random telephone survey examined the associations between illness representations of COVID-19 and behavioral intention to visit hospitals for scheduled medical consultations (BI-VHSMC), and the mediations via coping and fear of nosocomial infection among 300 Chinese adults. The prevalence of BI-VHSMC was 62.3%. Mediation analysis found that maladaptive coping (rumination and catastrophizing) and fear of nosocomial infection mediated the associations between various dimensions of illness representations of COVID-19 (e.g. consequence and controllability) and BI-VHSMC, both indirectly and serially. Illness representations, coping, and fear should be considered when planning related health promotion during the COVID-19 pandemic.
