The present study is a correlational research from research methodology perspective. The statistical population consists of married males and females in the city of Isfahan in 2015. A sample of 217 couples was selected randomly. In order to collect the research data, three questionnaires were used including researcher-developed questionnaire of participation in the social networks, questionnaire of tendency to divorce (Roosevelt et al., 1986), and questionnaire of marriage satisfaction (Enrich, 2000). In order to analyze the research data and test the hypotheses, Pearson Correlation Coefficient Test, Multi-variable Regression Model, and Structural Equation Modeling were used. Our findings reveled that females used social networks such as WhatsApp, Viber, Line, and Instagram more than males. The results of regression model revealed that there are significant relationships among participation in the social networks with marriage satisfaction and divorce tendency. In other words, increase in the participation in social networks lead to less marriage satisfaction and much divorce tendency.
