Couple satisfaction is seen as very important by all those in a romantic relationship; however, there are no recipes for it. Using a dyadic approach, we investigate how commitment and intimacy influence couple satisfaction and the moderator role of interpersonal emotion regulation (affect-improving and -worsening strategies). To achieve the scope of the study, we collected data from 131 couples, which were later analyzed using the actor-partner interdependence model with moderation (APIMoM). The results showed that the actor-effect of both commitment and intimacy on couple satisfaction is significant. We found mixed results for the partner-effect of the two variables. Both partners' strategies moderated the association between commitment and couple satisfaction. Women's use of affect-worsening strategies moderated the link between men's intimacy and women's couple satisfaction. The impact of the interactions of commitment or intimacy with interpersonal affect-improving and -worsening strategies on couple satisfaction is discussed further, as well as the implications and importance of the results.
