The main aim of the study is to have a better understanding of the effects that the COVID-19 crisis has had on people’s mental health. This research will help to better understand how people adapt to major health crises, and we also hope to understand how people cope with policies restricting their movements (e.g. lockdowns, curfews, social distancing, etc.) For instance, these results could inform government policies on how to tackle future public health crises similar to the current one. This survey is conducted in more than 10 countries, including Malaysia, Singapore, Indonesia, Thailand, Bangladesh, Iran, China, India, Australia, New Zealand, United States, Italy, Brazil, Sweden, Germany Canada etc.
