The main objective of the current research project is to evaluate the usability, satisfaction of the antenatal iCBT program including telephone coaching for antenatal and postnatal depressive symptoms and collect nationally representative data on population-based screening of antenatal depressive and anxiety symptoms. The overarching hypothesis is that iCBT, with easy access and affordability, is user friendly and well accepted. In addition to examining the treatment response by questionnaires, we will study the infant development comprehensively as well as potential physiological changes associated with antenatal depression or its treatment.
