Abstract

Objectives
：This study assessed the psychological impact of quarantine during the coronavirus disease 2019 (COVID-19) outbreak.
Methods
：A total of 2080 participants filled the self-report questionnaire from March 17 to April 20, 2020 in Daegu, Republic of Korea. An online link was sent to currently or previously quarantined participants. The self-report questionnaire included patient health questionnaire-9 (PHQ-9), generalized anxiety disorder-7 (GAD-7), primary care post-traumatic stress disorder screen for diagnostic and statistical manual-5 (PTSD-PC), state-trait anger expression inventory (STAXI), and P4 suicidality screener scale (P4). PHQ-9 score of 5 or more and 9 or less indicates mild to moderate depressive symptoms, and 10 or more indicates severe depressive symptoms; A GAD-7 score of 5 or more and 14 or less indicates mild to moderate anxiety symptoms, and a score of 15 or more indicates severe anxiety symptoms; A PTSD-PC-5 score of 2 indicates mild to moderate PTSD; a score of 3 or higher indicates severe PTSD; A STAXI score of 14 or higher indicates severe anger symptoms; In P4, the cut-off points for each self-report questionnaire were set as mild suicidal thoughts at 1 point or more and 2 points or less, and severe suicide thoughts at 3 or more points. Logistic regression analyses were used to explore COVID-19-related risk factors.
Results
：The prevalence of mental health symptoms among the survey respondents was at 52.5% for depression, 44.5% for anxiety, 39.4% for post-traumatic stress, 31.6% for anger, and 10.9% for suicidal ideation. Participants with confirmed or suspected COVID-19 family members showed a high risk for symptoms of anxiety, posttraumatic stress, and anger. Participants with financial loss had increased symptoms of depression, anxiety, posttraumatic stress, anger, and suicidal ideation. Participants with a history of medical/psychiatric illnesses reported more symptoms of depression, anxiety, post-traumatic stress, anger, and suicidal ideation. Having inadequate basic supplies during quarantine was associated with negative mental health outcomes.
Conclusions
：Quarantine had a negative psychological impact on all five mental health factors. The risk of depression, anxiety, post-traumatic stress disorder, anger, and suicidality increased among those who suffered from financial losses due to COVID-19. The associated risk factors will help identify populations at risk for mental health problems and implement mental health intervention policies.
