Afonso P, et al. - Researchers aimed at evaluating anxiety, depression and sleep quality in full-time teleworkers during lockdown imposed by the coronavirus disease 2019 (COVID-19) pandemic. In addition, they examined potential correlations between these variables, sociodemographic characteristics, quality of life and perceived productivity. In this cross-sectional study, 143 full-time teleworkers were assessed for anxiety, depression and sleep quality using validated clinical instruments. Among the participants, poor sleep quality was identified to be highly prevalent (74%, N = 106). Anxiety/depressive symptoms were reported among them with the predominance of anxiety and very high levels of sleep impairment. Overall researchers noted a higher prevalence of poor sleep quality in comparison with other studies conducted during the COVID-19 pandemic as well as high levels of anxiety and depression. Results thereby underscore the significance of accounting the potential negative impact of telework on mental health.
