The Mediation Role of Resilience and Psychological Inflexibility in the Relationship Between Attachment and Well-Being

Background: Attachment, as the emotional bond between children and primary caregivers, plays a crucial role in human development and has been linked to well-being in adulthood. However, the mechanisms underlying this relationship remain unclear. Methods: This cross-sectional study examined whether resilience and psychological inflexibility mediate the relationship between attachment styles and well-being. A total of 279 adults (61.2% women) completed the CaMir-R (attachment), the Connor-Davidson Resilience Scale, the Fusion and Avoidance Questionnaire, and measures of mental health and well-being. Data were analyzed using the PROCESS macro for SPSS. Results: Findings indicated that attachment style directly influences mental health and well-being. In addition, these relationships were mediated by resilience and psychological inflexibility, highlighting their role as protective and risk factors. Conclusions: Attachment is directly related to well-being, but resilience and psychological inflexibility play a mediating role. These findings suggest that interventions targeting these psychological strengths could enhance mental health. Results are discussed within attachment theory, underscoring practical implications for promoting strengths from early developmental stages.
