Optimal Question Selection from a Large Question Bank for Clinical Field Recovery in Conversational Psychiatric Intake — Panda et al. (2026) (arXiv:2604.22067, 2026)
What this evaluates
Evaluates sequential question-selection strategies for recovering target clinical fields from synthetic patient responses under a fixed interaction budget. It probes how well adaptive versus fixed questioning policies handle varying patient communication styles to maximize information coverage within conversational constraints.
Datasets
- Clinical Psychiatric Intake Vignette Benchmark — total ?; splits: test (300)
Metrics
accuracy(primary) — range: percent- Percentage of target clinical fields correctly recovered by the end of the interview session (max 20 turns or when all fields are recovered).
precision— range: percent- Percentage of recovered fields that are correctly labeled by the judge, measuring post-disclosure interpretation accuracy.
conversational_cost— range: other- Cumulative word count across the transcript, used to assess efficiency relative to accuracy.
Input / output format
Input: Current conversation transcript, in-loop recovery state, patient behavioral condition profile, and a question bank.
Output: A single question selected from the bank to ask the patient next.
Scoring recipe
def compute_metrics(recovered_fields, gold_fields, transcript):
total_target = len(gold_fields)
correct = sum(1 for f, v in recovered_fields.items() if f in gold_fields and v == gold_fields[f])
accuracy = (correct / total_target) * 100 if total_target > 0 else 0
precision = (correct / len(recovered_fields)) * 100 if len(recovered_fields) > 0 else 0
word_count = len(transcript.split())
return {'accuracy': accuracy, 'precision': precision, 'conversational_cost': word_count}
Common pitfalls
- Assuming higher transcript length or word count directly correlates with better performance; the paper shows the best strategy recovers more information per unit of conversational effort, not just longer transcripts.
- Overestimating the role of post-disclosure interpretation; precision is uniformly high (~98-99%), indicating the bottleneck is topic coverage and question selection, not field labeling.
- Ignoring behavioral condition heterogeneity; performance drops sharply for non-adaptive strategies under 'Guarded + Concise' conditions, masking overall strategy efficacy if averaged without stratification.
Evidence (verbatim from paper)
Random reaches 51.7%±19.6% mean accuracy, while form-based reaches 84.8%±15.8% and LLM-guided reaches 95.4%±8.1%. Precision remains uniformly high across all three strategies, ranging from 98.4% for random to 99.4% for LLM-guided.
