ABSTRACT
The datasets include relevant psychological and demographic variables relating to people's relationships, perceptions, and reactions to the Covid-19 pandemic. Participants were recruited from the United States (N = 396), China (N = 156), and Iran (N = 248). Participants were directed to an online survey that assessed their psychological well-being, affective states, factors related to life satisfaction, and their experiences with the Covid-19 pandemic. For the United States, participants were separated by developmental stage (e.g., young adults between 18 and 35 years old and older adults who were 55 years old or older). Participants from China and Iran were 18 years old or older. Participants from the United States also provided qualitative data in the form of a text-box response where they described their reactions to the Covid-19 pandemic. These data may be relevant for researchers who want to investigate cross-cultural or developmental differences in people's psychological states, perceptions, and reactions in the beginning phases of the Covid-19 pandemic.
