Teachers endorse disruptive behavior as a considerable concern for autistic students, which is compounded by the lack of adequate resources for behavioral intervention planning in the classroom. The RUBI program is an evidence-based, low-intensity manualized intervention, initially developed for parents of autistic children ages 3-14 and co-occurring disruptive behavior. Utilizing the Discover, Design/Build, Test (DDBT) framework, which combines user-centered design and implementation science, RUBI intervention content was collaboratively and iteratively redesigned with elementary school stakeholders (40 school staff from 28 schools) to ensure the feasibility, acceptability, and appropriateness of the redesigned intervention, RUBI in Educational Settings (RUBIES). Iterative quantitative and qualitative methods were conducted with stakeholders to identify targets for RUBI redesign. Conventional content analysis was used to code qualitative data and identify usability issues. Recommendations were provided for modifications to RUBI sessions to address the needs of the school context and end-users to develop RUBIES. Feasibility scores improved following the redesign. The use of the DDBT framework to redesign the RUBI intervention may promote greater usefulness and usability in school contexts.
