Cross-sectional study on university students' mental health during the COVID-19 pandemic: Exploring the influence of adverse and positive childhood experiences.

AIM

This study examined the psychological impact of the COVID-19 pandemic on university students, focusing on how adverse childhood experiences (ACEs) and positive childhood experiences (PCEs) influence mental health.

METHODS

A web-based survey was administered to 3000 university students from October 26 to 31, 2022, following the peak of the COVID-19 pandemic. Mental health assessments included the Japanese version of the Kessler Psychological Distress 6-Item Scale (K6) for depressive/anxiety symptoms, the Impact of Event Scale-Revised (IES-R-J) for distress, fear of COVID-19, and a three-item loneliness scale.

RESULTS

Of the respondents, 46.9% reported depressive/anxiety symptoms, 55.4% reported distress, and 37.3% reported fear of COVID-19. Factors such as current psychiatric treatment history and reduced income (either parental or personal) were predictive of worsening depressive/anxiety symptoms, distress, and loneliness. ACEs were found to exacerbate depressive/anxiety symptoms and distress, while PCEs mitigated these symptoms, and vice versa.

CONCLUSION

This study underscores the importance of considering both ACEs and PCEs in supporting the mental health of university students. PCEs were found to independently prevent mental health deterioration, including depressive/anxiety symptoms and distress, which may include post-traumatic stress disorder symptoms, even in the presence of ACEs. Recognizing and fostering PCEs emerged as an effective strategy for mitigating mental health issues.
