Outcome measures: scoring and cut-offs

Reference pages for the PHQ-9 and GAD-7, the two symptom measures at the core of NHS Talking Therapies: how each is scored, its published bands and cut-offs, how the service uses it, and where to get the official copy.

Scores, severity bands, and outcome classifications are computed by applying published clinical thresholds. They are informational aids, not diagnoses or clinical recommendations. Clinical interpretation remains the sole responsibility of the treating practitioner. These pages do not reproduce any questionnaire items and do not score responses.
