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

The purpose of this study is to propound the structural model of executive functions and extramarital relationship with the mediating role of marital commitment. 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. 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; 0.051, goodness of fit index; 0.942, normed fit index; 0.926, and comparative fit index; 0.942). 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.
