Health and Relationships Project, United States, 2014-2025 (ICPSR 37404)
The Health and Relationship Project is a longitudinal study of both spouses in same-sex and different-sex marriages who were legally married and aged 35 to 65 at Time 1 of data collection (2014-2015). Time 2 data were collected in 2021-2022 and Time 3 data were collected in 2024-2025.
At each time, both spouses completed a baseline questionnaire and a daily diary questionnaire (which was completed for 10 consecutive days); both components were completed online and spouses were asked to complete the surveys separately. The baseline questionnaire asks participants about a number of topics related to marriage and health, including stress, health status and health behaviors, relationship quality, and how they have approached health problems in the past. The diary questionnaire asks participants a number of questions about the past 24 hours, including daily stress experiences, social interactions, and health behaviors.
