Strength and limitations
This review extends the literature about the challenges in perinatal mental health care13,65,66 by giving a new broad overview of all current available therapies in this field and describing the role of collaborative care in this treatment. We limited our study to RCT’s only, which means we could have missed other potentially contributing studies. CBT and IPT were the most studied interventions, but we found a high heterogeneity within these interventions (e.g. content and number of sessions). Other interventions were studied by just a few trials. Also, retention and compliance rates were difficult to compare, because of the variation in the number of provided sessions and the time of follow-up. Another limitation is the lack of received additional information on CCC of the contacted authors, which could have led to an underestimation of the CCS’s. In short, this review gives a broad overview of studies, although there is high degree of heterogeneity on population, interventions and outcome measurements, which makes interpretation of findings difficult and decreases generalizability.
