Overview
GAD-7 (Generalized Anxiety Disorder-7) is a brief, clinically validated tool used to screen for anxiety disorders and measure anxiety severity.
Originally developed for use in primary care, GAD-7 is now widely used across mental health settings to support diagnosis, track symptom change, and evaluate treatment outcomes.
Its simplicity and strong psychometric properties make it a trusted assessment for outcome-focused care.
What Does GAD-7 Measure?
GAD-7 measures the frequency and severity of core anxiety symptoms experienced over the past two weeks.
It focuses on symptoms such as:
- Excessive worry
- Difficulty controlling worry
- Restlessness or feeling on edge
- Fatigue related to anxiety
- Difficulty concentrating
- Irritability
- Sleep disturbance due to anxiety
These symptoms align closely with diagnostic criteria for Generalized Anxiety Disorder (GAD) and other anxiety-related conditions.
Who Is GAD-7 For?
GAD-7 is appropriate for:
- Adults (18+)
- Adolescents (with clinical judgment)
It is commonly used by:
- Psychologists
- Psychiatrists
- Therapists and counselors
- Primary care providers
- Mental health clinics and community services
How GAD-7 Is Scored
Each of the 7 items is rated on a 4-point frequency scale:
- 0 – Not at all
- 1 – Several days
- 2 – More than half the days
- 3 – Nearly every day
Total Score Range
- Minimum score: 0
- Maximum score: 21
How GAD-7 Is Used
GAD-7 can be used at multiple stages of care to support both clinical insight and outcome measurement.
Common use cases include:
- Screening for anxiety disorders
- Supporting diagnostic assessment
- Monitoring symptom severity over time
- Evaluating treatment effectiveness
- Measuring outcomes for reporting and supervision
It can be administered:
- At intake
- At regular intervals during treatment
- At discharge or follow-up
Interpreting GAD-7 Scores
GAD-7 scores correspond to anxiety severity levels:
- 0–4: Minimal anxiety
- 5–9: Mild anxiety
- 10–14: Moderate anxiety
- 15–21: Severe anxiety
Scores of 10 or above often indicate clinically significant anxiety and may warrant further evaluation or intervention.
