The Philadelphia Alliance for Child Trauma Services II (PACTS)has been awarded a 5 year (October 1st 2016 to September 30th 2021) Community Treatment Center (Category III) grant by the Substance Abuse and Mental Health Services Administration (S.A.M.H.S.A.) through a National Child Traumatic Stress Initiative. PACTS: Reaching the Most Vulnerable Youth is a child and adolescent behavioral and physical health system-wide trauma universal screening, education, prevention and intervention program, with a focus on the most vulnerable and underserved youth: young children (2-6 years old); Lesbian, Gay, Bisexual, Transgender and Questioning (LGBTQ) youth; Commercially Sexually Exploited Children (CSEC); and intentionally injured youth (IY). We will primarily serve children eligible for Medicaid( which is a large percentage of the population of children in Philadelphia) under the age of 18 as well as transitional youth ages 18-21 in these populations. We have selected 3 trauma-specific evidence-based practices to serve our youth and families: Trauma-Focused Cognitive Behavioral Therapy(TF-CBT); Child and Family Traumatic Stress Intervention(CFTSI) and the Child and Adult Relationship Enhancement(CARE) group parenting training. We will partner with the following child-service systems: Child Welfare, Juvenile Justice, Physical Health, School District of Philadelphia, Crisis Response, Faith Based and Grass-roots organizations.
