Psychosocial and psychological interventions for treating postpartum depression.
BACKGROUND
Postpartum depression is a major health issue for many women from diverse cultures. While pharmacological interventions are an effective treatment for depression, mothers are often reluctant to take antidepressant medication due to concerns about breast milk transmission or potential side-effects. It is important that non-pharmacologic interventions be evaluated for use with postpartum women experiencing depressive symptomatology.


OBJECTIVE
Primary: to assess the effects of all psychosocial and psychological interventions compared with usual postpartum care in the reduction of depressive symptomatology.Secondary: to examine (1) the effectiveness of specific types of psychosocial interventions; (2) the effectiveness of specific types of psychological interventions; (3) the effectiveness of specific types of psychosocial interventions versus psychological interventions; (4) the effects of intervention mode (e.g., individual versus group-based interventions); and (5) the effects of sample selection criteria (e.g., targeting women with clinically diagnosed depression versus self-reported depressive symptomatology).


METHODS
CCDANCTR-Studies and CCDANCTR-References were searched on 1/8/2007, the Cochrane Pregnancy and Childbirth Review Group trials register, CENTRAL, MEDLINE (1966 to 2006), EMBASE (1980 to 2006) and CINAHL (1982 to 2006) using various combinations of the terms 'postpartum/postnatal depression.' Secondary references and experts in the field were used to identify other published or unpublished trials.


METHODS
All published, unpublished, and ongoing randomised controlled trials and quasi-randomised trials of psychosocial or psychological interventions where the primary or secondary aim was a reduction in depressive symptomatology.


METHODS
Both review authors participated in the evaluation of methodological quality and data extraction. Additional information was sought from several trial researchers. Results are presented using relative risk for categorical data and weighted mean difference for continuous data.


RESULTS
Ten trials met the inclusion criteria, of which nine trials reported outcomes for 956 women. Any psychosocial or psychological intervention, compared to usual postpartum care, was associated with a reduction in the likelihood of continued depression, however measured, at the final assessment within the first year postpartum. Both psychosocial and psychological interventions were effective in reducing depressive symptomatology. Trials selecting participants based on a clinical diagnosis of depression were just as effective in decreasing depressive symptomatology as those that enrolled women who met inclusion criteria based on self-reported depressive symptomatology.


CONCLUSIONS
Although the methodological quality of the majority of trials was, in general, not strong, the meta-analysis results suggest that psychosocial and psychological interventions are an effective treatment option for women suffering from postpartum depression. The long-term effectiveness remains unclear.
