Project Summary/Abstract Family therapy has emerged as one of the most efficacious interventions for child and adolescent behavioral and psychiatric issues and for chronic health conditions. However, widespread implementation of family therapy is often hampered by high training costs, re-training needs following staff turnover, low agency readiness to support new practices, and training strategies that lack ongoing implementation support and are prohibitively expensive. To better address the treatment needs of children and families, and to address long standing training and implementation challenges, we developed an innovative Family Therapy Training and Implementation Platform (FTTIP). FTTIP: 1) is guided by advances in implementation science, agency readiness, and knowledge of what it takes to sustain an evidence-based treatment; 2) uses adaptive training and consultation processes that provide a dynamic and data-driven procedure in which a competency is taught, measured, and the success or failure of the learning informs the next step of training in real time; 3) provides interactive practice of skills in which the trainee records interventions in response to simulation and receives personalized feedback; and 4) provides optional learning paths that allow the learner to explore additional ways to master the skills. Our Phase I study demonstrated the feasibility of FTTIP and set the stage for a fully-powered multisite Phase II Randomized Controlled Trial that will investigate whether FTTIP is “not inferior” to traditional face-to-face training on all key domains, including trainee competencies, agency readiness, and client outcomes. The Phase II study aims to: 1) Complete learning, practice and competency- testing paths that provide the learner multiple learning options and to increase the dynamic nature of the platform; 2) Demonstrate that 75 FTTIP trainees show improvement in all core family therapy competencies that are not inferior to 75 providers receiving traditional in-person family therapy training as tested using pre and post training measures in a clinical trial; 3) Demonstrate that 150 families (child/parent dyad) receiving CIFFTA family therapy show adequate retention in treatment, therapeutic alliance, and significant pre-post treatment improvements on family environment and presenting problems; 4) Establish the process (e.g., initiation and delays in training new staff) and cost associated with training in each of the two conditions; 5) Demonstrate that 15 agency leaders receiving FTTIP agency readiness consultations show more pre and post change in agency readiness and knowledge than 15 leaders receiving agency engagement as usual. FTTIP’s commercial application is that national, state, and local treatment services funders and providers will find FTTIP to be a highly cost effective, flexible, and engaging way to improve the quality of their evidence-based treatments (EBTs). By better preparing the nation’s workforce on EBTs, and ...
