The primary objective is to rigorously evaluate the effectiveness of the Infant Mental Health Home Visiting (IMH-HV) model on maternal and child outcomes according to legislative standards via a randomized controlled trial. The research team will recruit caregivers and their children (0-24 months) or pregnant women (n=72) from locations across Washtenaw County to participate in the IMH-HV RCT. Half of the women will be randomly assigned to a treatment as usual (TAU) control group (with access to all available community resources), and half of the women will be randomly assigned to the treatment group (i.e., IMH-HV). Women assigned to the control group will not receive IMH-HV treatment through the study team, but will not be prohibited from seeking or accessing IMH-HV treatment or any other services through community resources. Women assigned to the treatment group will receive IMH-HV treatment for 12 months through the study team with rigorous monitoring of fidelity to the IMH-HV model. All study participants will undergo assessments across the 12-month period of the treatment trial (i.e., baseline (randomization will occur after baseline), mid-points (3, 6 and 9 months) and follow-up (12 months) after randomization).
