Establishing usable innovations.
Test every new ABA tool for usability and write the fidelity checklist before you scale.
01Research in Context
What this study did
Fixsen et al. (2026) wrote a how-to paper. They tell teams to test every new ABA tool for usability before scaling it.
The paper lists five steps: name the core parts, try them with real staff, write a fidelity checklist, revise, and lock the final version.
What they found
The authors do not present new data. Instead they give a blueprint that any agency can copy to turn a pilot program into a replicable package.
How this fits with other research
Leung et al. (2017) found no agreed-upon way to use accelerometers with clients who have ID. Fixsen’s blueprint could end that chaos by forcing teams to pick one wear-time rule and stick to it.
Patton et al. (2020) showed that only some fitness tests work reliably for adults with ID. Their mixed results mirror Fixsen’s point: test first, cut the weak parts, then scale.
Dababnah et al. (2025) warned that outcome scales can drift over time. Fixsen answers with a fix: build a fidelity check into the package up front so drift is caught early.
Why it matters
Next time your agency wants to roll out a new data sheet, parent class, or token board, run it through the five-step usability loop first. You will leave the meeting with a one-page fidelity checklist and staff who know exactly what to do. That small pause saves months of drift and retraining later.

03Original abstract
The persistence of the science to service gap is evidence that evidence is not enough when defining evidence-based programs. Innovations must be developed with attention to the internal and external validity of the innovations themselves so that innovations can be replicated and scaled. This paper outlines the requirements for establishing an innovation, recommends standards for a usable innovation, and describes the usability testing processes to meet those requirements. Usability testing is a systematic process to efficiently and effectively determine the essential components and to develop a fidelity measure for an innovation. Usability testing is the foundation for research to establish the internal validity (“the basic minimum without which any experiment is uninterpretable”) and external validity (“asks the question of generalizability”) of the innovation itself. Once the essential components of a usable innovation are defined, measured, and linked with outcomes, implementation and scaling of usable innovations with fidelity can narrow the science to service gap.
