Adherence to preventive behaviors among college students during COVID-19 pandemic in China: The role of health beliefs and COVID-19 stressors.

Before herd immunity is reached, preventive practices still play an important role in controlling the COVID-19 pandemic. Adherence to preventive behaviors could be determined by individuals' health beliefs, which would be influenced by antecedent factors such as previous exposure to pandemic stressors. Applying the health belief model (HBM), this study aims to examine the mediation association among COVID-19 stressors, HBM constructs, and preventive behaviors. Longitudinal data were collected from 1225 Chinese college students using web-based surveys at wave 1 (w1; between January 31 and February 11, 2020) and wave 2 (w2; between March 20 and April 3, 2020). Participants reported their COVID-19 stressors (w1), five HBM constructs (w2), and preventive behaviors (w1 and w2). Paired t-tests suggested that social distancing and self-quarantine behaviors decreased while precautionary behaviors increased from w1 to w2. Path analysis indicated that two HBM constructs (perceived barriers and self-efficacy) mediated the association between COVID-19 stressors and precautionary behaviors. These findings suggested that tailored prevention intervention for college students should attend to perceived barriers and self-efficacy. Individuals who exposed to multiple pandemic stressors merit particular attention and intervention should account for their early pandemic stress experiences.
