In the present pilot study the feasibility and efficacy of Baby Triple P- an antenatal parent training- are investigated. Healthy becoming first time parents were randomly allocated to either the Baby Triple P parent-training group or a care as usual control group. It is expected that 78 couples of becoming first time parents are recruited. It is hypothesized that parents and their infants in the parent training group will show significantly less psychopathology / regulation problems and better partnership quality than participants in the control condition.

In this pilot study, the efficacy and feasibility of the Baby Triple P parenting training is investigated in a pilot study using a randomized controlled trial. According to the efficacy of the parenting training, it is expected that parents in the training condition show higher scores on mental health scales (BSI-18) and quality of Partnership (PFB). Furthermore, it is expected that infants whose parents has taken part in the parenting training have lower severity ratings of regulatory disorders assessed with the Baby-DIPS diagnostic interview than infants of parents in the care as usual control condition.
