PHQ-9, GAD-7, CORE-OM: The Clinical Scores Your Therapist Wishes You Understood
Your therapist uses validated clinical instruments to measure your progress. Most clients have no idea what these scores mean or why they matter. Understanding them changes how you experience therapy.
Numbers That Actually Mean Something
When you go to a doctor for a physical problem, you expect measurements: blood pressure, heart rate, cholesterol levels. These numbers tell your doctor what is happening, whether treatment is working, and when to adjust the approach.
Mental health has the same kind of precise instruments. They have been developed, validated, and refined over decades of clinical research. Yet most people in therapy have never heard of them, and most platforms do not use them at all.
This is a problem. Without objective measurement, therapy relies entirely on subjective feeling. "Do you feel better?" is a useful question, but it is not the same as "Your depression score dropped from 18 to 9 over the last three months." One is an impression. The other is evidence.
Cozecare includes 13+ established screening questionnaires, not as optional extras, but as core components of the therapeutic ecosystem. Here is what they actually measure and why understanding them transforms your therapy experience.
The Big Three: PHQ-9, GAD-7, and CORE-OM
PHQ-9: Patient Health Questionnaire (Depression)
The PHQ-9 is the most widely used depression screening instrument in clinical practice. Developed by Pfizer and validated in over 600 studies, it measures nine symptoms of depression on a 0-3 scale.
Score Ranges:
- 0-4: Minimal depression
- 5-9: Mild depression
- 10-14: Moderate depression
- 15-19: Moderately severe depression
- 20-27: Severe depression
Why It Matters: A score change of 5 or more points is considered clinically significant. If your score drops from 16 to 10 over two months, that is not just "feeling a bit better." It represents a measurable, clinically meaningful improvement from moderately severe to moderate depression.
GAD-7: Generalized Anxiety Disorder Scale
The GAD-7 measures seven core symptoms of anxiety on a 0-3 scale. It is validated for screening generalized anxiety, social anxiety, panic disorder, and PTSD.
Score Ranges:
- 0-4: Minimal anxiety
- 5-9: Mild anxiety
- 10-14: Moderate anxiety
- 15-21: Severe anxiety
Why It Matters: Anxiety fluctuates more than depression. A single score tells you little. A trend across weeks tells you everything: is anxiety reducing over time? Are there spikes correlated with specific triggers? Is treatment working?
CORE-OM: Clinical Outcomes in Routine Evaluation
The CORE-OM is broader than PHQ-9 or GAD-7. It measures four dimensions: subjective wellbeing, problems/symptoms, life functioning, and risk. Used extensively in UK clinical services, it captures a holistic picture of psychological health.
Why It Matters: Some people improve on depression scores but their overall functioning does not change. CORE-OM catches this by measuring multiple dimensions simultaneously.
Beyond the Big Three: Additional Assessments on Cozecare
DASS-21: Depression, Anxiety, Stress Scale
Measures all three conditions in one 21-item questionnaire. Particularly useful when symptoms overlap, which is common.
Custom Metrics
Cozecare allows therapists to create custom tracking metrics specific to your treatment goals. Tracking alcohol consumption, exercise frequency, social interaction, or any behavior relevant to your therapy.
Personalized Check-In Questions
Beyond standardized assessments, Cozecare's daily check-ins can include therapist-customized questions that track specific aspects of your therapeutic journey.
How Cozecare Uses These Assessments Differently
Most platforms that include assessments treat them as intake forms: you fill them out once when you sign up, and they gather dust.
Cozecare treats assessments as living, longitudinal tools:
- Periodic re-assessment: Your therapist schedules regular re-assessments to track change over time
- Automated scoring: No manual calculation errors. Scores are computed instantly.
- Trend visualization: See your scores plotted over weeks and months in clear visual dashboards
- Therapist alerts: Significant score changes trigger alerts so your therapist can respond quickly
- Integration with check-ins: Assessment trends are correlated with daily check-in data for richer clinical insight
What This Means for You as a Client
Understanding your scores changes your relationship with therapy:
- Motivation: Seeing a PHQ-9 score drop from 17 to 11 provides concrete evidence that the work is paying off, even on days when you do not feel different
- Informed conversations: "My GAD-7 was 14 two months ago and now it is 8" is a more productive starting point than "I think maybe I feel a bit less anxious"
- Treatment decisions: If scores plateau after several months, it may be time to try a different therapeutic approach. The data makes this conversation objective instead of subjective
- Self-awareness: Tracking scores over time reveals patterns you would never notice through subjective reflection alone
A Real Example
A client begins therapy with a PHQ-9 of 19 (moderately severe depression) and a GAD-7 of 16 (severe anxiety). After 3 months of weekly therapy with daily Cozecare check-ins:
- PHQ-9: 19 to 11 (moderate depression, a clinically significant 8-point improvement)
- GAD-7: 16 to 9 (mild anxiety, a clinically significant 7-point improvement)
- CORE-OM: Overall functioning improved by 34%
This example illustrates how questionnaire scores may support a conversation with a psychologist; it does not predict or guarantee an outcome.
Start Measuring Real Change
If you are in therapy without validated assessments, you are navigating without a compass. You might be making progress. You might be stuck. Without measurement, neither you nor your therapist knows for certain.
Cozecare includes PHQ-9, GAD-7, CORE-OM, DASS-21, and 9 more validated instruments, all integrated into a continuous ecosystem of daily check-ins, therapeutic plans, and automatic session summaries.

Your progress deserves to be measured, not guessed.
