Couples’ Communication Behaviors and Diurnal Cortisol Patterns

Previous research suggests that more negative or less positive couple communication can be stressful and that chronic stress can lead to less healthy patterns of physiological stress functioning. Our goal was to investigate whether couples’ observed communication behaviors and reported relationship conflict were related to diurnal cortisol patterns, an important indicator of hypothalamic–pituitary–adrenal axis functioning. Sixty-two couples (n = 124 individuals) reported marital conflict and were video-recorded engaging in a coded conflict discussion. Diurnal cortisol samples were collected. Results suggested that men’s greater observed communication quality predicted women’s higher awakening cortisol levels as well as men’s steeper decreases in cortisol across the day (i.e., slopes), men’s greater reported conflict predicted women’s lower awakening levels, and, in some models, women’s greater reported resolution predicted women’s lower awakening levels and men’s steeper slopes. These findings suggest that less positive and more negative marital conflict contribute to dysfunction of the hypothalamic–pituitary–adrenal axis.
