PainTrain-AI Pilot: Feasibility, Usability (SUS) and Concept-Shift in Primary Care and a Specialized Setting

Condition(s) studied

Investigational drug(s) / intervention(s)

PainTrain-AI Behavioral Training: PainTrain-AI is a behavioral educational intervention delivered through a digital clinical simulation platform. The system uses a retrieval-augmented generation (RAG) safety architecture to ensure that all responses are generated only from validated pedagogical content. Participants engage in simulated dialogues with virtual standardized patients to practice biopsychosocial reasoning about chronic pain. The intervention is non-diagnostic, does not provide clinical advice, and does not involve patient data. All participants receive the same intervention.

Study summary

This pilot will assess feasibility and usability (SUS) and explore concept shift (reduction of neurophysiology misconceptions) after exposure to a behavioral educational intervention (PainTrain AI), a digital clinical simulation "fenced" by evidence (RAG) for safe, non diagnostic training. The study will be conducted in Primary Care and in a specialized comparative setting, without patient data collection. Primary endpoint: SUS score. Secondary endpoints: concept shift, adherence to micromodules, and interaction latency as friction metric. The platform does not generate clinical advice; it retrieves validated teaching content.

Eligibility

Primary outcome measure(s)

• Usability (SUS, 0-100) — 4-8 weeks after onboarding
  Usability will be assessed using the System Usability Scale (SUS), a validated 10-item questionnaire that yields a score from 0 to 100. Higher scores indicate better usability. Participants will complete the SUS after interacting with the PainTrain-AI educational simulation for the predefined training period. The primary feasibility criterion is achieving a mean SUS score ≥75, indicating good usability.
