Avoidant &nbsp;&nbsp;and ambivalent &nbsp;&nbsp;attachment styles and immature defense mechanisms &nbsp;&nbsp;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 &nbsp;&nbsp;acts as a moderator in the association between secure attachment style and marital adjustment.
