PHQ-9 and GAD-7 labels were strongly correlated in the dataset. PHQ-9 was used as a 0-27 depression severity score with moderate and severe thresholds at 10 and 15. GAD-7 was used as a 0-21 anxiety severity score with thresholds at 5, 10, and 15. Labels came from self-administered questionnaires rather than clinician diagnostic interviews. The models predict screening scores related to severity scales rather than formal diagnoses.
