Not a diagnostic tool. The PHQ-9 and GAD-7 are validated screening and severity-tracking instruments, not diagnostic instruments, a raised score indicates the likelihood and severity of symptoms, and any clinical decision should be confirmed by a qualified clinician through direct interview.

About these scales

The PHQ-9 is the nine-item depression module of the Patient Health Questionnaire, developed by Kroenke, Spitzer and Williams and validated as a standalone severity measure in 2001. Each item maps directly onto a DSM criterion for major depressive disorder, so the same nine responses double as a screen and a severity score. It is free to use, reproduce, and distribute without permission.

The GAD-7 is the seven-item anxiety screener developed by Spitzer, Kroenke, Williams and Löwe in 2006. It's the most widely used brief measure of generalized anxiety disorder severity in primary care and psychiatric settings, and is likewise free to use.

Why we didn't build a self-scoring HAM-D

The Hamilton Depression Rating Scale is clinician-administered through a structured interview, not a self-report form, rater judgment on several items makes a simple web form an unreliable substitute. MindFlow's clinical notes module includes a guided HAM-D interview flow for use inside a real consultation, where a clinician's judgment can inform each item.

How practices use this

Most clinics use PHQ-9/GAD-7 scores at intake and then again every few visits to track whether treatment is working, a change of 5 points or more is generally considered a clinically meaningful shift. MindFlow's patient portal can send these questionnaires to patients before a visit and score them automatically inside the chart, so the clinician sees the trend line the moment the patient walks in.
