The ability to tolerate the infidelity-induced distress can be influenced by a variety of factors. According to these varieties, the aim of the present study was to investigate the mediating role of cognitive flexibility and stress perception in the relationship between psychological capital and forgiveness with distress tolerance in couples. The method of present study was a correlational study of structural equation type. which between them 215 person were selected by random cluster sampling method. They completed the distress tolerance, psychological capital, and Forgiveness and stress perception questionnaires. Data were analyzed by using SPSS-22 software and analysis of indexes fitness in moment structures (AMOS). The results were supported the fitness of the proposed model after control of overlap between two variables. The results of structural equation analysis and regression indicated to the significance coefficients of direct path in the final model. Also According to the first path, the mediate role of the cognitive flexibility was identified in the relationship between psychological capital and forgiveness with distress tolerance in couples. But in the second path, it was found that the stress perception variable has a modulating role in the positive effect of forgiveness and psychological capital on distress tolerance. Based on these results, it can be concluded that although psychological capital and forgiveness have a positive direct effect on distress tolerance in couples the suffering of marital infidelity.
