Purpose: The purpose of this research is to determine the effects of Attachment and Biobehavioral Catch-up (ABC), an evidence-based parenting program, on stress biomarkers in children. Participants: The study will involve approximately 150 caregiver-child dyads, with children aged between 24 and 42 months. Participants will include primary caregivers fluent in English or Spanish, along with their children who have experienced social risk factors for adversity. Procedures (Methods): Participants will be randomly assigned to either receive the ABC parenting program (10 sessions) immediately or be placed on a wait-list, receiving the program after about 4 months. The study procedures include caregivers completing online surveys, engaging in play-based observational tasks with their children, and collecting non-invasive biological samples (saliva, cheek swab, hair) from the children and saliva samples from the caregivers at 2-3 time-points.
