Families living in urban poverty, enduring chronic and complex traumatic stress, and having difficulty meeting their children's basic needs have significant child maltreatment risk factors. There is a paucity of family focused, trauma-informed evidence-based interventions aimed to alleviate trauma symptomatology, strengthen family functioning, and prevent child abuse and neglect. Trauma Adapted Family Connections (TA-FC) is a manualized trauma-focused practice rooted in the principles of Family Connections (FC), an evidence supported preventive intervention developed to address the glaring gap in services for this specific, growing, and underserved population. This paper describes the science based development of TA-FC, its phases and essential components, which are based on theories of attachment, neglect, trauma, and family interaction within a comprehensive community-based family focused intervention framework.
