RESUMEN
Romantic relationships have the potential to be a great source of support or a significant stressor depending on the quality of the relationship. Given the importance of these relationships, it is important to explore possible predictors of relationship quality, primarily if such predictors can be targeted in a clinical setting. Relationship mindfulness, or the propensity to be mindful in the setting of a romantic relationship, is one such option. The current study explored the associations between relationship mindfulness, negative relationship quality, and physical health. An online assessment was completed by 116 middle-aged different-sex couples that measured the variables of interest. In addition, an Actor-Partner Interdependence Mediation Model was utilized to determine significant associations between relationship mindfulness, negative relationship quality, and physical health for both actors and partners. The clinical implications are that relationship mindfulness may help to decrease negative relationship quality and subsequently benefit individual physical health.
