Mt. Hope Family Center's Project Sustaining Change will provide training, consultation, and technical assistance for child- and family-serving organizations and systems to improve dissemination and implementation of evidence-based treatment models for child trauma. Focusing on sustainability through organizational supports will promote longer-term accessibility to services for traumatized children, adolescents, and their families and enhance supports for best practices in child-serving systems. Goals of Sustaining Change include to: 1) expand access to evidence-based treatment for children and youth who have had traumatic experiences, and assist organizations in adopting and providing evidence-based models of intervention, 2) support organizations in identifying evidence-based interventions that fit the needs of their population served and organization, and in achieving successful evidence-based implementation through Implementation Science principles, 3) facilitate sustainability of evidence-based interventions through consultation and Leadership Forums, and 4) assist organizations in gaining an understanding of trauma-informed care, and adopting the guiding principles to embed trauma-informed care within their organizations and systems. Evidence-based training for 50 clinicians in Interpersonal Psychotherapy for Adolescents will improve access to treatment for traumatized youth with depressive symptoms and provision of Child-Parent Psychotherapy by 50 clinicians will improve access to trauma-informed treatment for children under age six and families. This training will be offered through 8 Learning Collaboratives. Education on evidence-based intervention in child welfare and mental health organizations will be provided through 5 webinars and 2 Leadership Forums. Through a partnership with the TRANSFORM National Child Center on Child Abuse and Neglect, Sustaining Change synergistically will leverage existing resources that translate research into best practices to maximize reach and depth of trauma-informed care to break the intergenerational transmission of trauma and assist organizations in adopting and providing evidence-based models of intervention. Consultation on trauma-informed organizational transformation will support 3 reflective supervision cohorts, improve prevention of secondary traumatic stress, and change agency climate to enhance workforce development and integrate SAMHSA's trauma-informed principles into practice for 2-5 organizations. Training will be targeted to child-serving organizations nationally, and will include over 1000 professionals trained over the course of the project. Trainings and consultation will include in-person, webinars, videoconferencing, leadership forums, and access to resources through the TRANSFORM website and social media. Evidence-based interventions and principles of trauma-informed care exist that can successfully impact the lives of individuals who have experienced trauma. Sustaining Change can offer hope through its network of supports and prepare the next generation of supervisors and practitioners to implement evidence-based trauma treatments into practice in sustainable ways.
