RESUMEN
Attachment is an important predictor of relationship satisfaction and attachment insecurities are a risk factor for couples under stress. Drawing from the Vulnerability-Stress-Adaptation model, we investigated whether dyadic coping strategies (DCS) would explain the links between attachment insecurities and relationship satisfaction in 97 couples involved in medically assisted reproduction (MAR). Path analyses revealed that for women and men, attachment insecurities (anxiety, avoidance) were associated with their own lower relationship satisfaction through their lower use of positive DCS. Attachment avoidance was also associated with participants' own lower relationship satisfaction through their own lower use of negative DCS. Men's attachment avoidance was also related to their partner's lower relationship satisfaction via their own and their partner's lower use of positive DCS. The findings suggest that promoting the use of positive DCS may be important to preserve relationship satisfaction in couples involved in MAR.
