Although used in 9 countries including the United States, scaling and widespread dissemination is challenging. We discuss key revisions to TAP to facilitate dissemination including matching assessments to those used in different practice settings, translation of materials into different languages, providing worksheets to help trainees adapt TAP to local contexts and a training/certification online experience using story board, an interactive media integrated onto the Blackboard learn management system, to provide on-demand training modules. The learning platform allows learners to engage with others, preview modules and share experiences. Revisions enable greater flexibility for program adaptation yet adherence to its core principles. With over 150 trainees, we use REAIM to evaluate effectiveness of modifications and to understand implications for its reach.
