Effect of marital satisfaction on self-regulation efforts in couples: Value of heart rate variability measurements.

This study explored self-regulatory efforts during the viewing of couple interactions and their association with relationship satisfaction. High-frequency heart rate variability (HF-HRV) was measured for each participant during a video recall of a recent couple interaction to quantify the self-regulatory processes governed by parasympathetic activity. Among 30 couples, HF-HRV was measured continuously during three specific periods to explore its change over time using a video-recall procedure: (1) resting state; (2) viewing of couple interactions (expressing daily life situations and conflictual interactions); and (3) recovery.

Stress, dyadic coping, and relationship satisfaction: A longitudinal study disentangling timely stable from yearly fluctuations.

The aims of the present study are to analyze the associations of different forms of dyadic coping (i.e., own supportive dyadic coping = OSDC; perceived supportive dyadic coping provided by the partner = PSDC; common dyadic coping = CDC) with relationship satisfaction, and to investigate whether these effects differ depending on the amount of perceived stress.
