The mediator role of psychological inflexibility in the relationships between relationship satisfaction, resilience and adult attachment styles in emerging adulthood

The main purpose of this research is to investigate the mediator role of psychological inflexibility in the relationship between relationship satisfaction, attachment styles and resilience in emerging adulthood. In this study, which is progressing quantitatively, relational survey models were used. In this context, relevant models were tested in the sample group formed with 773 participants who studied at 13 faculties or colleges and were in a romantic relationship for at least 3 months in 2023-2024 at Niğde Ömer Halisdemir University using proportional and random sampling methods. The data were collected face to face using the Personal Information Form, the Experiences in Close Relationship-II (ECR-II), the Happiness in Relationships Scale, the Brief Resilience Scale (BRS) and the Acceptance and Action Questionnaire-II (AAQ-II). In the analysis of the data, t test, pearson correlation coefficient, multiple regression analysis and hierarchical regression analysis were applied for independent samples. The mediating role between variables is handled with the PROCESS Macro Model 4 Plugin. The significance of the indirect effects was realized by the Bootstrap method. According to the research results, it has been seen that psychological inflexibility in adulthood, which appears, had a mediating role in the relationship between anxious attachment style and resilience, but also had a mediating role in the relationship between avoidant attachment style and resilience. However, it has been concluded that psychological inflexibility does not had a mediating role in the relationship between anxious attachment style and relationship satisfaction, it also does not had a mediating role in the relationship between avoidant attachment style and relationship satisfaction.
