This study explored the differences in mindfulness qualities between various conflict regulation styles and attachment styles. Differences in relationship satisfaction were also examined in various conflict regulation styles. Seventy-nine individuals who have been in a monogamous relationship for at least one year and are co-habiting completed an online survey comprised of the Freiberg Mindfulness Inventory (FMI), Rahim Organizational Conflict Inventory-II (ROCI-II), Experiences in Close Relationships Inventory-Revised (ECR-R) and Multidimensional Relationship Questionnaire (MRQ). Results revealed significant differences in mindfulness and relationship satisfaction between conflict regulation styles. These results suggest that mindfulness qualities of openness, acceptance and non-judgment can be enhanced in clinical settings to improve conflict regulation outcomes and relationship satisfaction regardless of an individual’s adult attachment orientation.
