The Mediating Role of Marital Satisfaction in the Relationship Between Midlife Crisis and Tendency to Infidelity Among Middle-Aged Men and Women in Rasht County

This study aimed to investigate the mediating role of marital satisfaction in the relationship between midlife crisis and the tendency to infidelity among middle-aged men and women in Rasht. The research was descriptive-correlational with a structural equation modeling design. The statistical population included all married men and women aged 40 to 60 in Rasht in 2023, and 200 individuals were selected through convenience sampling. The research instruments included the Midlife Crisis Inventory (MCI), the Tendency to Infidelity Scale (ITS), and the ENRICH Marital Satisfaction Questionnaire. Data were analyzed using structural equation modeling and AMOS software. The findings revealed that midlife crisis had both a direct and an indirect effect through the mediation of marital satisfaction on the tendency to infidelity. In other words, reduced marital satisfaction resulting from midlife crisis can lead to an increased tendency to engage in extramarital relationships. Additionally, there was a significant positive correlation between midlife crisis and the tendency to infidelity, and a significant negative correlation between marital satisfaction and the tendency to infidelity. These findings highlight the importance of addressing midlife crisis and enhancing marital satisfaction as key factors in preventing the tendency to infidelity in the middle-aged population.هدف
