Mental Health Status before and during the COVID-19 Pandemic in Patients First Visiting a Psychosomatic Internal Medicine Clinic in Tokyo, Japan

Abstract

The coronavirus disease (COVID-19) pandemic has aggravated anxiety and depression worldwide, particularly in patients with chronic illnesses and mental disorders. Using validated questionnaires, in this paper, we examine the psychological effects of the pandemic in Japan in detail. The General Mental Health Scale (GHQ), the State–Trait Anxiety Inventory (STAI), and the Center for Epidemiologic Studies Depression Scale (CES-D) were used to assess mental health, state and trait anxiety, and depression, respectively. The survey was completed during the patients’ first visits to the clinic of Psychosomatic Internal Medicine from November 2018 to April 2021. The Mann–Whitney U test was used to compare data from 226 participants before and during the COVID-19 pandemic. The GHQ total, GHQ subscales of “social dysfunction” and “anxiety and dysphoria”, and state anxiety scores were significantly higher during than before the pandemic. The GHQ total, some GHQ subscales, and state anxiety scores were significantly higher among male than female participants during the pandemic. The GHQ total, some GHQ subscales, CES-D, and state anxiety scores in those aged 10–39 years were significantly higher. Thus, the COVID-19 pandemic may have caused mental health changes in many individuals based on their gender, age, and with time.

“…However, COVID-19 is still gradually becoming a global public health crisis with incalculable damage to people’s physical and mental health [ 2 ]. Numerous experiments on specific psychiatric disorders during COVID-19 have shown that prolonged social isolation can produce a range of negative emotions, such as irritability, fear, anxiety, and sadness [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ], leading to a range of psychological problems such as insomnia, rising depression and anxiety, loneliness, and even more serious suicidal ideation [ 10 , 11 , 12 , 13 ]. Moreover, a literature review systematically studied the impact of the COVID-19 pandemic on psychological and psychosocial factors and proposed the “psychological COVID-19 syndrome”, with anxiety, stress, and depression becoming the greatest distress during the epidemic; these psychological problems caused by the COVID-19 pandemic are in urgent need of relief [ 14 ].…”
