Early psychological impact of the 2019 coronavirus disease (COVID-19) pandemic and lockdown in a large Spanish sample

Background Epidemic outbreaks have significant impact on psychological well-being, increasing psychiatric morbidity among the population. We aimed to describe the early psychological impact of COVID-19 and its contributing factors in a large Spanish sample, globally and according to mental status (never mental disorder NMD, past mental disorder PMD, current mental disorder CMD). Methods An online questionnaire was conducted between 19 and 26 March, five days after the official declaration of alarm and the lockdown order. Data included sociodemographic and clinical information and the DASS-21 and IES questionnaires. We analysed 21207 responses using the appropriate descriptive and univariate tests as well as binary logistic regression to identify psychological risk and protective factors. Results We found a statistically significant gradient in the psychological impact experienced in five domains according to mental status, with the NMD group being the least affected and the CMD group being the most affected. In the three groups, the depressive response was the most prevalent (NMD =40.9%, PMD = 51.9%, CMD = 74.4%, F= 1011.459, P< 0.001). Risk factors were female sex and classification as a case in any psychological domain. Protective factors were younger age and ability to enjoy free time. Variables related to COVID-19 had almost no impact except for having COVID-19 symptoms, which was a risk factor for anxiety in all three groups. Conclusions Our results can help develop coping strategies addressing modifiable risk and protective factors for each mental status for early implementation in future outbreaks.
