Prediction of Extramarital Relationships Based on Executive Functions With the Mediatory Role of Marital Commitment

Objective: The purpose of this study is to propound the structural model of executive functions and extramarital relationship with the mediating role of marital commitment. Methods: The samples were selected by convenience sampling method. In experimental situation, for assessing the executive function of the participants did computerized exams, including Stroop test, Wisconsin test, Go-No-Go test, N-Back test, completed commitment questionnaire of Rusbult, and attitudes toward infidelity scale of Whatley. The obtained data were analyzed using regression and structural equation modeling. Results: Executive functions, including inhibition, task switching, working memory, and commitment, directly affect the extramarital relationship through the mediation of commitment. The model has a suitable fit (average root mean square second approximation error; ۰.۰۵۱, goodness of fit index; ۰.۹۴۲, normed fit index; ۰.۹۲۶, and comparative fit index; ۰.۹۴۲). Conclusion: Executive functions (including inhibition, task switching, working memory), and marital commitment play an important role in extramarital relationships; therefore, they should be taken into consideration.
