The purpose of this study is to examine the effectiveness of the Fathers and Babies intervention (FAB). FAB aims to improve the mental health of fathers and provide strategies that help fathers support the mental health of their female partner. FAB was adapted from Mothers and Babies (MB), an evidence-based perinatal depression prevention intervention. FAB can be delivered as a standalone intervention or can be delivered alongside MB as a dyadic intervention to both fathers and mothers. In this longitudinal randomized controlled trial (RCT), the investigators will examine the effectiveness and implementation of the FAB intervention. To do this, the investigators will partner with Home Visiting (HV) programs in the state of Illinois (IL) and Texas (TX). Home visitors will be randomized to receive (intervention) or not to receive (controls) the FAB training. Home visitors that are randomized to receive FAB training will be trained and implement FAB or FAB with MB.

The specific aims include:

1. To evaluate the effectiveness of FAB, delivered as a stand-alone intervention, in improving paternal mental health outcomes compared to a control group that does not receive the FAB intervention;
2. To evaluate the effectiveness of FAB, when delivered in conjunction with MB, in improving paternal and maternal mental health outcomes compared to a control group that does not receive the FAB or MB intervention.
3. To evaluate FAB implementation to inform future intervention delivery and scalability; the investigators will assess key implementation outcomes guided by the RE-AIM framework (feasibility, acceptability, barriers, facilitators, reach, adoption, implementation, and maintenance).
