Cognitive behavioral therapy in perinatal mental health: An overview of systematic reviews.

Aim: The purpose of this study was to determine whether cognitive behavioral therapy (CBT) started in pregnancy can prevent depression and anxiety.

Methods: We conducted an overview review by selecting systematic reviews (SRs) that compared CBT with usual care, no CBT, or interventions other than CBT in perinatal women. We restricted the review to studies that included randomized controlled trials. The results of included SRs were descriptively integrated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Results: Seven SRs met our eligibility criteria. One SR was limited to CBT interventions, whereas others included psychoeducation and interpersonal psychotherapy. There was some variation in the number of sessions and timing of CBT, and whether there was a postpartum intervention. Five SRs showed that CBT reduced depression compared with usual care, an educational intervention, or no intervention. One SR that analyzed the effect on anxiety found that psychotherapy, including CBT, reduced anxiety compared with usual care or no intervention.

Discussion: CBT starting from pregnancy may be effective as a preventive intervention for postpartum depression and anxiety, although the degree of effectiveness varied.

Conclusions: This overview review aimed to clarify whether CBT is effective in preventing depression and anxiety from pregnancy. CBT may be effective in reducing perinatal depression and anxiety.
