ABSTRACT
Background: College students are a uniquely vulnerable group and may experience high stress levels due to COVID-19, especially for girls. This study aims to identify the post-traumatic stress disorder (PTSD) symptoms and related factors among the target population during the initial phases of the COVID-19 pandemic. Methods: A cross-sectional online survey was conducted during the initial phases of the COVID-19 pandemic in China. A total of 2205 college female students from six provinces enrolled in this study and completed the questions about cognitive status of COVID-19, the Impact of Event Scale-6 (IES-6), the Multidimensional Perceived Social Support Scale (MPSSS) and a self-developed 10-item Perceived threat scale. Univariate and multivariate logistic regression were performed by SPSS software to explore the determinants of PTSD symptoms. Results: PTSD symptoms were prevalent in this sample of college female students, and 34.20% met the cut-off for PTSD. Self-reported fair or poor health (AOR=1.78, 95%CI: 1.22-2.59), high concern about COVID-19 (AOR=1.66, 95%CI: 1.35-2.03), beliefs that 'COVID-19 can cause a global outbreak' (AOR=1.26, 95%CI: 1.02-1.56), the perception of ‘risk of infection’ (AOR=2.46, 95%CI: 2.16-2.81), beliefs that ‘closed management’ and ‘COVID-19 as a public health emergency of international concern’ would have an impact, and the fear of ‘impact on life planning’ were all positively associated with PTSD (AOR=1.37, 1.22 and 1.29, respectively), whereas perceived social support from family (AOR=0.81, 95%CI: 0.70-0.93) was negatively associated with PTSD. Among the significant variables at the bivariate level, multivariate logistic regression revealed that the greatest protector for PTSD was the high knowledge score (AOR=0.73, 95%CI: 0.60-0.90), while had confirmed cases among relatives and friends (AOR=7.70, 95%CI: 1.28-46.25) was the strongest predictor of PTSD. Conclusions: In summary, PTSD symptoms were prevalent among college female students in China during the COVID-19 epidemic. Targeting vulnerable populations to improve their knowledge of COVID-19 and create an atmosphere of social support would be beneficial to improve the mental health of the female students during the COVID-19 epidemic.
