How might the procedures for data collection look for this response?Data collection would likely focus on direct observation during DTT sessions, using a simple fidelity checklist to mark correct versus incorrect implementation of each step in the trial (for example, SD delivery, prompt level, reinforcement, and error correction). This could be collected during brief probes a few times per week so the data feel manageable and directly tied to coaching, rather than overly evaluative
Identify an intervention, or set of interventions, based on the PDC-HS data.

Since the PDC-HS points to the training domain, I would start with a targeted BST refresher that includes clear instructions, live modeling of correct DTT, opportunities for Stephanie to practice, and immediate feedback. If errors persist, I might add brief in-vivo coaching during sessions to support generalization while keeping the intervention focused and easy to maintain
