The purpose of this study was to assess the psychological impacts of quarantine during COVID-19 outbreak. Materials and method: Self-report questionnaire was conducted from March 17, 2020, to April 20, 2020 including the outburst period in Daegu, Republic of Korea. Two-thousand and eighty subjects were participated. The online link was sent to the subjects who were now quarantined (NQ) or past-quarantined (PQ). 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 (STAX-I), and P4 suicidality screener scale(P4). Results: Among 2080 subjects 52.5% (95% CI, 50.3%-54.7%) for PHQ-9, 44.5% (95% CI, 42.4%-46.7%) for GAD-7, 39.4% (95% CI, 37.3%-41.6%) for PTSD-PC, 31.6% (95% CI, 29.6%-33.6%) for STAX-I, and 10.9% (95% CI, 9.6%-12.3%) for P4 exceeded cutoff value. NQ group (n = 608, 29%) show more anger than PQ (n = 1472, 71%) (aORs, 1.417 [95% CI, 1.119-1.796]). Especially subjects who were quarantined for more than 28 days in NQ (n = 238, 39%) had high risk for symptoms of PHQ-9 (aORs, 1.428 [95% CI, 1.081-1.886]), GAD-7 (aORs, 1.326 [95% CI, 1.008-1.744]), PTSD-PC (aORs, 1.427 [95% CI, 1.083-1.879]), and STAX-I (aORs, 1.354 [95% CI, 1.017-1.802] than PQ . Conclusion: Our result suggest that quarantine have negative psychological effects such as depression, anxiety, post-traumatic stress disorder, anger. In particular NQ experiences more anger than PQ and the longer the period, the more depression, anxiety, PTSD, and anger.
