The survey was conducted by researchers at the University of Colorado School of Medicine, who collected data from 58,408 healthcare workers in 208 organizations between April and December 2020. Respondents were asked, "Due to…COVID-19, I am experiencing concerns about childcare," and subsequently assessed their CCS on a scale of 1, "not at all," to 4, "a great extent," with a score of 3 or 4 representing high CCS.
