Introduction: Given the influence of postpartum depression on patterns of parent-child relationships, in this study we aimed to determine detached mindfulness in meta-cognitive therapy on postpartum depression.

Methods: In this quasi-experimental study, the study sample included 30 patients among 89 patients referred to Bozorgmehr clinic in Tabriz in 2014, who had postpartum depression. Four weeks after delivery and after clinical interview and completing Beck Depression Inventory, depression was diagnosed. After eight sessions (two sessions a week, 90 minutes per month) of detached mindfulness-based cognitive therapy, depression questionnaire was administered in both groups. The data was analyzed using SPSS version 16 and analysis of covariance.

Results: The results of analysis of covariance showed that after the intervention, the average post-test in the test group decreased significantly (P = 0.026). Thus, this treatment reduced the rate of postpartum depression in the patients under study.

Conclusions: These findings may have important implications in the use of detached mindfulness in meta-cognitive therapy on postpartum depression.
