Objective: This study aimed to investigate a causal model of marital quality of life based on psychological resilience with the mediating role of sexual satisfaction in married teachers. Methods and Materials: The research employed a descriptive-correlational design using structural equation modeling (SEM). The sample consisted of 375 married teachers selected through purposive sampling. Data were collected using the Connor-Davidson Resilience Scale (CD-RISC), the Sexual Satisfaction Questionnaire by Hudson et al., and the Revised Dyadic Adjustment Scale (RDAS) by Busby et al. Descriptive statistics and inferential analyses were conducted using SPSS and AMOS software. Assumptions of normality, linearity, and multicollinearity were checked and confirmed prior to model testing. Findings: The results revealed a significant direct effect of resilience on marital quality of life (β = 0.42, p < 0.001), indicating that higher resilience is associated with greater marital quality among married teachers. However, the indirect effect of resilience on marital quality of life through sexual satisfaction was not statistically significant (β = 0.10, p = 0.113), suggesting that sexual satisfaction does not mediate the relationship between resilience and marital well-being in this population. Model fit indices confirmed the adequacy of the proposed model (χ²/df = 2.54, RMSEA = 0.05, CFI = 0.94, NFI = 0.91, GFI = 0.95, AGFI = 0.93). Conclusion: Resilience plays a crucial and independent role in enhancing marital quality of life among married teachers, while sexual satisfaction, despite its overall importance, does not serve as a mediating factor in this relationship. The findings underscore the importance of psychological strengths in marital dynamics and suggest the need for interventions that enhance resilience to promote relational well-being, especially in high-stress professional contexts.
