Understanding Mental Health Screening Scores
These self-assessments are educational screening tools, not medical tests. They cannot diagnose any condition. Only a licensed clinician can provide a diagnosis.
If you've taken a depression or anxiety questionnaire at a doctor's office — or on this site — you've met one of medicine's most practical tools: the standardized screening scale. Here's what those numbers actually mean, and just as importantly, what they don't.
Why clinicians use questionnaires at all
Mood and anxiety don't show up on lab work. Screening scales solve a real problem: they turn "how have you been feeling?" into a consistent measurement that can be compared across visits. When a clinician sees a PHQ-9 drop from 18 to 9 over six weeks of treatment, that's meaningful evidence the treatment is working. The questionnaires on this site are the same ones used in clinics, presented in their standard form.
The PHQ-9, in plain English
The PHQ-9 asks about the nine symptom areas clinicians consider when evaluating depression — mood, sleep, energy, appetite, concentration, self-worth, interest in activities, physical restlessness or slowing, and thoughts of self-harm. Each answer scores 0 to 3, for a total of 0 to 27. The commonly used bands are: 0–4 minimal, 5–9 mild, 10–14 moderate, 15–19 moderately severe, and 20–27 severe. In many clinical settings, scores of 10 and above prompt a fuller evaluation.
The GAD-7, in plain English
The GAD-7 does the same job for anxiety in seven questions about worry, restlessness, irritability, and dread, scored 0 to 21. The bands: 0–4 minimal, 5–9 mild, 10–14 moderate, 15–21 severe. Like the PHQ-9, it was designed for screening and for tracking change over time, and it's often repeated across appointments for exactly that reason.
The PCL-5, in plain English
The PCL-5 is a 20-item checklist for posttraumatic stress symptoms, developed by the U.S. National Center for PTSD. It covers four symptom clusters — intrusive memories, avoidance, negative changes in thinking and mood, and changes in arousal and reactivity — scored 0 to 80 in total. Research studies often use a threshold in the low 30s as the point where further evaluation for PTSD may be worthwhile. Diagnosing PTSD itself requires a structured clinical interview; the checklist's job is to flag when that conversation makes sense.
What screening scores can't tell you
A score is a snapshot, not a verdict. It can be pushed up by a bad week, poor sleep, a physical illness, or a stressful stretch at work — and pushed down by a good day that doesn't reflect the month around it. Screening tools also can't distinguish between conditions that share symptoms. That's why no reputable clinician diagnoses from a questionnaire alone, and why an elevated score means "worth a real evaluation," never "you have this condition."
How to actually use your results
Print or write down your score and bring it to an appointment — any clinician will know exactly what a PHQ-9 or GAD-7 number means, and it gives your first conversation a running start. If you retake a tool later, compare the numbers: direction of change over time is often more informative than any single score. And a score doesn't need to reach a particular threshold before help is reasonable — if what you're feeling interferes with your life, that alone is a good enough reason to talk to someone.
