Abstract: Objective： To explore the relationship of adult attachment with depression level in pregnant women. Methods： Relationship Questionnaire（RQ） and Experience of close relationships（ECR） inventory were used to assess the adult attachment in 176 participants. Center for Epidemiologic Studies Depression Scale（CES-D） was used to measure the depression level. Results： ①Distribution of adult attachment style in pregnant women was： 57.2% secure， 21.4% dismissing， 15.0% preoccupied and 6.4% fearful. ② Secure participants（11.58±7.09） were at the significantly low level of depression score when compared with the dismissing（18.16±10.85）、 fearful（18.82±7.68）， and preoccupied（21.65±10.55） participants （F＝12.78，P＜0.01）；③ CES-D score showed the significantly positive correlations with attachmently avoidance（r=0.445，P＜0.01） or attachment anxiety（r=0.215， P＜0.01）. Conclusions： Adult attachment was significantly correlated to depression level in pregnant women.
