Effectiveness of video self‐monitoring for training and maintaining procedural fidelity during covert observations

Paden and team asked clinic staff to film their own DTI sessions. After each session, staff watched the clip and filled out a short fidelity checklist.

The study ran in a private ABA clinic with four technicians. The researchers later watched the same clips without staff knowing to score true fidelity.

Self-scoring kept fidelity above a large share even when the BCBA was not in the room. Gains stayed high for eight weeks with no extra coaching.

Covert checks matched staff self-scores, so the teams were not inflating numbers.

Bartle et al. (2026) also used video to train staff, but they had trainees watch a model film instead of watching themselves. Both studies raised fidelity, so you can pick self-watch or model-watch based on time and staff skill.

Nangle et al. (1993) first showed that kids who track their own work finish more math problems. Paden flips the idea: adults track their own work to keep DTI sharp.

Jobin (2019) proved DTT still works for preschoolers with ASD. Paden gives you a cheap way to guard the quality of that DTT when you can’t observe every trial.

You no longer need to choose between high fidelity and high caseload. Hand staff a tablet, have them record and score one short clip per shift, and you get weeks of accurate DTI without extra supervision hours. It’s free, fast, and travels home with them if you run telehealth sessions.
