Evaluation of a self-instructional manual for conducting discrete-trials teaching with children with autism.
A short DIY book plus a 10-dollar prize teaches brand-new staff to run DTT at 88 % fidelity in under five hours.
01Research in Context
What this study did
Carly’s team wrote a 4.5-hour self-teach book that shows 21 DTT moves step-by-step.
They gave the book to 6 college students who had never run trials.
If a student hit 88 % correct on a checklist, they also got 10 dollars.
What they found
After reading and practice, every student scored 88 % or better on the checklist.
When they later worked with a real child with autism, their DTT stayed at 77 % accuracy.
The whole training took less than five hours and no live coach was needed.
How this fits with other research
Schroeder et al. (2014) say teachers should probe both tact and listener skills right away to save time. Carly’s manual trains the same fast, clean DTT that review calls for.
Carnett et al. (2016) blended DTT with time delay to teach kids to ask questions. Carly shows you can first train adults to run those DTT steps with just a book and a small bonus.
Cox et al. (2017) used prompting plus DRO to keep kids still for MRI. Carly uses prompting plus a tiny cash DRO to keep adult trainees accurate—same principle, new goal.
Why it matters
You can mail the manual to new hires, let them train themselves, and still hit 80 % fidelity before they touch a client. That slashes supervisor hours and gets staff billable faster. Try it next week: give the packet, set a 90 % mastery goal, and pay a five-bill bonus—see if your rookie RBTs match Carly’s 88 %.

03Original abstract
Discrete-trials teaching (DTT) is commonly used to implement applied behavior analysis treatment for children with autism. The authors investigated a revised self-instructional manual for teaching university students to implement a 21-component DTT procedure to teach three tasks to confederates role-playing children with autism. Also, as a motivational contingency, for each DTT session in which a student scored at or above 90% accuracy, they received US$10. After an average of 4.5 hr to master the training manual, students' average DTT performance improved from 52% in baseline to 88% while teaching a confederate. Students averaged 77% DTT performance during subsequent generalization sessions with a child with autism.
