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.
