Results: In this study, the best model for factor analysis was determined to be the item-response multivariate factor analysis method and with the aid of this model, two dimensions were reported for the Gottman questionnaires. Also, the items factor loadings, the parameters of the Item-response theory and the analysis of the Items were reported. Conclusion: At the end, two dimensions of "fight mode" and "positive and negative emotions towards marriage and spouse" were identified for these questionnaires.
