The COVID-19 pandemic and ensuing isolation measures has had negative psychological impact on the general population of China, measured by mean levels of stress, depression and anxiety. Authors conducted a cross-sectional study (Jan. 31 - Feb. 2) (n=1210, from 194 cities) using an online questionnaire disseminated to university students who were encouraged to pass it along. Overall, 75.5% of respondents reported psychological impacts resulting from the pandemic. Women, students, presentation of various symptoms (ex: dizziness, coryza), and low reported health-status are high risk-factors for worsened mental health. Identifying populations vulnerable to psychological distress, and factors favouring psychological health, provide insight for the formulation of psychological interventions.
