The Mediating Role of Psychological Inflexibility in the Relationship Between Resilience and Marriage Satisfaction Among Parents of Children With Developmental Disabilities: A Multigroup Bayesian Structural Equation Modeling Approach

This study examined the mediating role of psychological inflexibility in the relationship between resilience and marriage satisfaction among parents of children with developmental disabilities in a Turkish sample using Bayesian structural equation modeling (BSEM). Data were collected from 420 participants using the Acceptance and Action Questionnaire-II, the Connor-Davidson Resilience Scale, and the Marriage Life Scale. Results supported the hypothesized model with adequate fit (PPP = .48), with psychological inflexibility partially mediating the relationship between resilience and marriage satisfaction. Resilience was negatively associated with psychological inflexibility (β = −.73, 95% CI [−0.78, −0.68]), and psychological inflexibility was negatively related to marriage satisfaction (β = −.31, 95% CI [−0.40, −0.22]). The indirect effect of resilience on marriage satisfaction through psychological inflexibility was significant (β = .23, 95% CI [0.16, 0.30]). Gender differences were examined, with results suggesting similar structural patterns across genders, though males showed slightly higher levels of resilience and marriage satisfaction. The findings highlight the importance of psychological inflexibility as a mechanism through which resilience influences marriage satisfaction in parents of children with developmental disabilities.
