Implementing Multi-system Programs to Strengthen Attachment in Children and Families Affected by Trauma (IMPACT) serves children ages 1-7 and their families impacted by trauma and at risk for, or are involved with, the child welfare system in marginalized communities in East Tennessee. Our goals are to increase awareness and community engagement around trauma, decrease traumatic stress symptoms and disruptive behavior in young children, and decrease caregiver stress by improving their ability to parent children with trauma histories. We will increase identification of young children with trauma by partnering to provide a web-based trauma screening training product for the young children’s system of care and increase implementation of trauma screening instruments for young children with community mental health partners. We will coordinate dissemination efforts with community mental health centers to implement Parent-Child Interaction Therapy (PCIT) and two modifications to target trauma symptoms and emotion regulation. PCIT-Trauma Directed Interaction adds a trauma component to PCIT to help caregivers manage trauma reactions. PCIT with Toddlers supports caregivers of children ages 12-24 months with behavior and emotion dysregulation to help their child better regulate their feelings and behavior by strengthening attachment. We will work with foster parents, relative caregivers, and kinship placements through the Resource Parent Curriculum—Child-Adult Relationship Enhancement (RPC-CARE), in concert with the Center for Children and Families (CCFH), to educate and support families of young children to better understand the impact of trauma on children’s behaviors, and give them specific skills to successfully parent. IMPACT will expand workforce capacity to support families by working with case workers and other non-clinical staff in the CARE model, which will be implemented in outpatient and in-home settings. We will also support providers working with families to address secondary traumatic stress with Reflective Supervision and Consultation (RS/C) workshops followed by monthly reflective consultation groups. Reflective consultation gives providers the space to reflect on their work with families, consider cultural and contextual elements of their work, and mitigate the effects of secondary traumatic stress. IMPACT will engage the community and families by partnering with Tennessee Voices for Children and forming an Advisory Board to meet semi-annually to guide the IMPACT project. The Advisory Board will guide project personnel on services accessibility, review and provide input to address implementation barriers, assist with achieving cultural sensitivity to materials and engagement strategies and advise on sustainability. We anticipate serving at least 30 people the first year of the grant, then increasing that capacity to 74 families per year for a total of at least 300 families over five years.
