| Intervention(s) | A single session of behavioral economic communication training using AI-simulated patients (interaction with 3 cases and reviewing feedback, approx. 40-50 min) for three cohorts: (1) junior physicians (3-7 years post-grad), (2) specialty-trained physicians in Endocrinology and Diabetes, and (3) board-certified diabetologists. |
Outcome(s)
| Primary Outcome | Change in AI-generated total score for behavioral economic communication skills from Pre-test to Post-test (approximately 40-50 minutes after the start of the study). |
|---|---|
| Secondary Outcome | Change in self-efficacy (confidence levels, Q1-Q4) from Pre-test to Post-test. Change in the number of dialogue turns (rounds of conversation) required to reach a consensus with the AI patient. Mean scores of the System Usability Scale (SUS) in the post-intervention questionnaire. Comparison of baseline AI-generated scores among the three groups (junior, specialty-trained, and expert physicians) to verify construct validity. |
