Conclusion
In conclusion, there is an important lack of evidence in the field of perinatal mental health care. Available evidence now focusses on studies evaluating CBT and IPT for treating perinatal depression. More research is recommended on other psychiatric disorders, interventions and long-term follow-up outcomes. Additionally, collaborative care and especially a multi-professional approach to patient care is already implemented in most available interventions. However, interprofessional communication and multidisciplinary teams of more than two different professionals are rare. More trials are needed (on the impact of interprofessional communication) to be more conclusive whether collaborative care is a key component in perinatal mental health care.
