摘要:Early empirical data shows that schoolaged children and adolescents are experiencing elevated levels of anxiety and depression during the COVID-19 pandemic. However, there is only scarce evidence regarding the mental health and wellbeing impact on infants and pre-school-aged children. This global study aims to (a) describe and compare the COVID-19 related experiences within and across countries; (b) examine mental health outcomes for young children (1 to 5 years) and (c) caregivers over a 12-month period during the COVID-19 pandemic; (d) identify the risk and protective factors for child and caregiver emotional wellbeing. In this presentation, we will outline the background, study design, and measures for global collaboration. Method: We have developed partnerships with eight international sites (Australia, Cyprus and Greece, The Netherlands, Poland, Spain, Turkey, the United Kingdom, and the United States of America). Research partners are collecting data from caregivers of young children aged 1-5 years old on 4 occasions (baseline and 3-, 6- 12-months). Caregivers answer questions online about COVID-19 related exposure and experiences, their child’s wellbeing, their own mental health, and parenting. Results: The course of psychological wellbeing and the impact of risk and protective factors will be analysed using multivariate models accounting for nested effects (e.g. region) and repeated measures. Conclusions: The findings from the COVID-19 Unmasked global collaboration will directly translate into mental health promotion and prevention models for the early years by informing public health advice and identifying factors that contribute to positive outcome trajectories.
