The current study attempts to explore the interaction between adult romantic attachment and cognitive-experiential decision making in predicting relationship satisfaction in couples and well-being in college students. The author introduces a model that suggests cognitive-experiential self-theory can be a useful framework for understanding how individuals with different attachment profiles make important relational decisions that may affect their current and future relationship satisfaction. In study one, 52 heterosexual married couples completed questionnaires assessing their attachment style, self-theory, and relationship satisfaction in order to test the hypothesis that attachment style and relational decision making interact to predict relationship satisfaction. In study two, 75 college students completed similar questionnaires assessing well-being instead of relationship satisfaction. Results suggest that the interaction between adult romantic attachment and cognitive-experiential decision-making processes are not predictive of an individual's own marital satisfaction but rather their partner's. Additionally, results suggest that the interaction is predictive of student's personal and relational well-being. Implications and directions for future study from these exploratory studies are provided.
