A longitudinal study of mental health in healthcare workers in Japan during the initial phase of COVID-19 pandemic: comparison with the general population

The COVID-19 pandemic negatively impacted the mental health of people in Japan. Healthcare workers (HCWs) especially suffered from poor mental health, engaging with COVID-19 patients while protecting themselves from infection. However, a long-term assessment of their mental health in comparison to the general population remains to be conducted. This study evaluated and compared changes in mental health between these two populations over a six-month period. Measures of mental health, loneliness, hope and self-compassion were completed at baseline and at six-month follow-up. Two-way MANOVA (Time x Group) identified that no interaction effects were present. However, at baseline, HCWs had higher levels of mental health problems and loneliness, and lower levels of hope and self-compassion than the general population. Furthermore, a higher level of loneliness was found in HCWs at six months. These findings highlight strong feelings of loneliness in HCWs in Japan. Interventions such as digital social prescribing are recommended.
