How do our relationships change as we grow older? Unfortunately, most research on marriage and dating has focused almost exclusively on the relationships of young adults. Thus, interventions designed to help people have happier, healthier relationships are being informed by studies conducted on a limited segment of the population. This project, which is funded by a grant from the National Science Foundation, collected data from almost 300 couples. The purpose of the study is to compare older and younger couples, both married and dating, to examine potential age-related changes in how couples approach relationship challenges, as well as the implications of different coping strategies for emotional and physical health. Thank you to all the couples who participated!
