Project Abstract Family Therapy Training and Implementation Platform (FTTIP) was developed to address EBT training and implementation challenges. FTTIP 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. It provides interactive practice of skills in which the trainee records interventions in response to simulation and receives personalized expert feedback. The supplement project will have multiple components that augment the parent study by collecting qualitative data that we can combine with the parent study’s quantitative data to better understand the experiences of trainees and agency leaders with the platform. Twenty trainees (randomly selected from the 75 CIFFTA parent study trainees) and 16 agency leaders from the sample of the parent study will be included. The proposed supplement aims to: 1) gather perceptions and experiences of the trainees about the process of learning and practicing specific CIFFTA competencies from the platform (time 1 interview) and later, about their unique experiences related to implementation of the EBT, delivery of competencies learned, and the application of EBT in a real-world context (time 2); and 2) gain a deeper understanding from leaders of their experiences in facilitating EBTs at their agencies, the identification of barriers that can be addressed by the organizational readiness work (time 1), and later regarding their agencies experience with the platform, consultation process, perceived cost-benefit, and agency readiness (at time 2). The proposed supplement also includes a comprehensive career development and training plan during which the trainee gains experience in all the issues relevant to planning, conducting, and reporting on randomized trials, state of the art training and consultation processes, measuring family competencies, assessing, and intervening in organizational readiness to implement EBTs, data analysis, dissemination, and grant writing. Mentorship will include training in animation and simulation, quantitative data analysis to assist in the analyses of data for the parent grant, and qualitative research for the supplement study. Marketing and commercialization activities will include enrolling in a marketing course and assisting the benefit cost analyses expert in the parent study. Supplement study data will augment the parent study work in understanding the leadership decision-making process regarding the selection of EBTs, and training and implementation plans.
