Abstract
BACKGROUND: Due to the COVID-19 pandemic, a state of emergency was declared in Japan and university classes were suspended, causing concern about the deterioration of the mental health of isolated students. This study aimed to understand students' mental health status during the COVID-19 pandemic and suggest measures to prevent depressive anxiety among them. METHOD: Undergraduate and graduate students at one national and two private universities in the Kansai region were surveyed. The Kessler Psychological Distress Scale-6 was used to assess the students' mental health. Questions were included to assess students' awareness of COVID-19 and changes in lifestyle habits, including drinking, smoking, gaming, and other addictive habits. The University of Tokyo Health Sociology's version of the Sense of Coherence Scale was used to assess the ability to cope with stressors. RESULTS: More than 50% of undergraduate and graduate students felt more than mild depressive anxiety and approximately 11% felt severe depressive anxiety, indicating that anxiety about the future worsened the levels of depressive anxiety. Life with reversed day and night schedules was associated with the worsening of depressive anxiety levels, but a high sense of coherence was associated with decreased levels of depressive anxiety. CONCLUSION: COVID-19 pandemic triggered isolation which led to worsening the mental health of undergraduate and graduate students. Psychological support for lifestyle and a sense of coherence is necessary to prevent mental health deterioration among isolated students. LIMITATIONS: As we were unable to contact all students, the sample bias may affect interpretation of the data.
