National Couples' Health and Time Study (NCHAT)

Logo for the National Couples' Health and Time Study

The National Couples’ Health and Time Study (NCHAT) is a nationally-representative, multi-method study of cohabiting and married individuals ages 20 to 60 who were in a same- or different-gender couple in the United States during the COVID-19 pandemic. The sample includes 3,642 main respondents and 1,515 spouses/partners. The survey and time diary with experience sampling methods focus on relationship functioning, emotion regulation, discrimination, racial trauma, physical health, psychological well-being, health behaviors, stressors, and time use.

NCHAT is funded by the Eunice Kennedy Shriver National Institute of Child Health & Human Development, The Office of the Director, and the National Institute on Minority Health and Health Disparities (5R01HD094081-04, 1U01HD108779-01, & 1R03HD107126-01). This project also benefited from support provided by the University of Minnesota’s Minnesota Population Center (P2CHD041023) and the Bowling Green State University’s Center for Family and Demographic Research (P2CHD050959).
