Aim: The present study aimed at modeling distress tolerance of couples with marital infidelity based on psychological capital and defective metacognitive beliefs through psychological flexibility. Methods: The method of this study was descriptive-survey with structural equation correlation design. The statistical population of the study included all married men and women experienced marital infidelity and referred to family counseling centers in Tehran in the first half of 2019. Cluster random sampling method was used in this study. The selected sample of the present study included 400 men and women who were evaluated using a questionnaire individually. Data were collected using demographic characteristics questionnaires, distress tolerance scale, psychological capital questionnaire, psychological flexibility questionnaire, and metacognitive beliefs questionnaire. AMOS and Spss22 software was used for data analysis. Results: The results revealed that the model designed to explain distress tolerance in couples with marital infidelity had acceptable fit indices. Accordingly, the relationship between psychological capital and defective metacognitive beliefs variables and distress tolerance was confirmed with mediating role of psychological flexibility in the form of path analysis. Therefore, the variable of psychological flexibility played facilitator role in the relationship between psychological capital and distress tolerance, while psychological flexibility moderated and reduced the relationship between defective metacognitive beliefs and distress tolerance. Conclusion: according to these results, it can be stated that in explaining the distress tolerance of people with marital infidelity, various factors such as psychological flexibility can play a mediating role and it can be stated that high flexibility facilitates and increases the effect of psychological capital on improving distress tolerance but moderates the role of defective metacognitive beliefs. Thus, based on these results, it is recommended to consider the role of individual variables of cognitive flexibility affecting anxiety tolerance.
