Policy-Sensitive Fairness Evaluation in Automated Scoring of Clinical Communication
Paper · 2026 · Saed Rezayi, Le An Ha, Victoria Yaneva et al.
Summary
The paper asks whether an automated scorer of medical students' patient-communication skills treats demographic groups equally, and whether that answer changes depending on how much each error type is penalized. The setting is formative: the Communication Learning Assessment (CLA) tool, where learners record spoken replies to video patient cases. Four trained NBME annotators marked case-specific patient-centered behaviors (PCBs) in these replies. ACTA, a DeBERTa-based encoder model, detects the same behaviors.
The authors define an encounter-level loss that weights false negatives and false positives with adjustable coefficients. They then compare groups by gender and race using a disparity measure that is adjusted for case. FN:FP ratios range from 1:5 to 5:1.
With equal weights, no group differences reach statistical significance. Across the other ratios the picture also stays largely stable, apart from a few isolated exceptions. The authors argue that error weighting is a value judgment and should be stated explicitly. In formative tools this matters because missed credit can discourage learners, while unearned credit can hide gaps in their skills.
Key points
- The data cover 1,383 records from 223 US 3rd- and 4th-year medical students across 8 clinical cases. A rubric defines 25 PCBs, with 1–4 per case. Annotators were blind to learner demographics.
- ACTA reached an average binary F1 of 0.92 per PCB (range 0.86–0.97). Fairness was assessed on out-of-fold predictions from 5-fold cross-validation.
- Human-annotated PCB prevalence was similar across the large groups, at roughly 59–63%. Small gender groups were reported only descriptively.
- Uncertainty was estimated with 1,000 bootstrap resamples stratified by case, and Bonferroni correction was applied.
- The only significant gaps appeared in the White/Caucasian vs Asian comparison at 2× and 3× FN weight. These gaps vanished at higher weights, and the authors treat them as a possible Type I error or a local effect.
