This study aimed to investigate the association between individuals’ attachment styles and their marital satisfaction through positive relational behaviors (PRBs). This was a correlational study, of structural equation modeling (SEM) type. Out of all married students of Bu-Ali Sina University, 261 (69 men and 192 women) filled out our questionnaires. The results from SEM indicated that the hypothesized model in this study had a good fit with the study sample. The secure attachment style demonstrated a significant positive relationship with marital satisfaction through PRBs, while the ambivalent and avoidant attachment styles exhibited a negative association with marital satisfaction through PRBs.
