The predictive role of attachment styles and decision-making styles in romantic relationship satisfaction

This study explores the predictive roles of attachment styles and decision-making styles on university students' romantic relationship satisfaction. While social relationships are known to impact psychological well-being, romantic relationships hold particular importance. This study investigates how secure, anxious, and avoidant attachment styles, along with rational, intuitive, avoidant, and panicked decision-making styles, jointly affect relationship satisfaction. Using a relational survey model, data were collected from 485 university students through the Personal Information Form, Relationship Satisfaction Scale, Three-Dimensional Attachment Styles Scale, and Melbourne Decision-Making Styles Scale-II. Analyses included Pearson Correlation, Standard Multiple Regression, and Hierarchical Multiple Regression, with assumptions such as normality, linearity, and multicollinearity tested. The findings indicated that attachment and decision-making styles together significantly explained 53% of the variance in relationship satisfaction. Secure attachment and rational decision-making were positive predictors, while anxious/avoidant attachment and panicked/avoidant decision-making were negative predictors. Hierarchical regression showed that attachment styles alone explained 28.6% of the variance, increasing to 53% with decision-making styles included. These results highlight the significant influence of attachment and decision-making patterns on romantic relationship satisfaction.
