The Association between Attachment Styles and Marital Adjustment: The Moderating Role of Defense Mechanisms

Background: Researches on attachment theory shows that attachment styles influence marital adjustment. However, some psychological factors moderate this correlation. The present study was aimed to examine the moderating role of defense mechanisms in the association between attachment styles and levels of marital adjustment. Methods: This descriptive-correlational study collected data from a convenience sample of 300 married individuals (150 men, 150 women) using the Adult Attachment Inventory (AAI), Golombok Rust Inventory of Marital State (GRIMS) and Defense Styles Questionnaire (DSQ). Results: The results showed that the secure attachment style   and mature defense mechanisms   were significantly correlated with marital adjustment. Avoidant   and ambivalent   attachment styles and immature defense mechanisms   were negatively correlated with marital adjustment. The neurotic defense mechanism was not significantly correlated with marital adjustment. The results showed that mature and immature defense mechanisms   acts as a moderator in the association between secure attachment style and marital adjustment. Besides, mature defense mechanisms moderated the association between avoidant attachment style and marital adjustment. Furthermore, immature defense mechanisms  had moderated the association between ambivalent attachment style and marital  adjustment (p<0.001). Conclusion: Therefore, based on the results, the attachment styles and defense mechanisms would predict marital adjustment.
