This is the protocol for a review and there is no abstract. The objectives are as follows:
The primary objective of this review is to assess the effects of psychosocial and psychological interventions compared with usual postpartum care in the reduction of depressive symptomatology.
Secondary objectives are to examine:
(1) the effectiveness of specific types of psychosocial interventions (e.g. non-directive counselling, support groups);
(2) the effectiveness of specific types of psychological interventions (e.g. interpersonal psychotherapy, cognitive behavioural therapy);
(3) the effects of intervention mode (e.g. individual versus group-based interventions);
(4) the effects of sample selection criteria (e.g. targeting women with clinically diagnosed depression versus self-reported depressive symptomatology).
