Researchers have developed PTTSD, a novel probabilistic framework designed to detect depression severity from clinical interview transcripts. This system utilizes LSTMs and self-attention mechanisms to predict PHQ-8 scores, offering calibrated uncertainty estimates alongside predictions. The framework includes variants for sequence-to-sequence and sequence-to-one predictions, with the former allowing for temporal analysis of confidence evolution during an interview. Evaluated on E-DAIC and DAIC-WOZ datasets, PTTSD demonstrates competitive performance among text-only systems and highlights the clinical utility of uncertainty-aware predictions. AI
