Anxiety Tests Explained: BAI vs. GAD-7
When, why, and how to use two of the most common anxiety scales.
The two most commonly used tools for measuring anxiety symptoms are the Beck Anxiety Inventory (BAI) and the Generalized Anxiety Disorder-7 (GAD-7). Both measure anxiety, but they serve different purposes. This article compares the key differences.
Quick comparison
- BAI: 21 items, total 0–63. Measures the severity of physical anxiety symptoms in detail (palpitations, sweating, trembling).
- GAD-7: 7 items, total 0–21. A fast screen focused on generalized anxiety disorder; 10 or above is a common cut-off.
When to use the BAI
If you want to assess the physical/somatic component of anxiety in detail, the BAI is a good choice. It is useful for measuring symptom severity when panic-like symptoms are prominent.
When to use the GAD-7
For rapid screening, primary-care assessment, or regular monitoring of treatment response, the GAD-7's brevity is a major advantage. With only 7 items, it can be administered remotely and frequently.
Which one for which situation?
| Situation | Recommended |
|---|---|
| Rapid screen / initial assessment | GAD-7 |
| Severity of physical anxiety symptoms | BAI |
| Frequent monitoring of treatment response | GAD-7 |
| Detailed symptom profile | BAI |
What they share: Neither provides a diagnosis
Both scales are for screening. A high score indicates intense symptoms but does not diagnose an anxiety disorder. The result is interpreted only within a mental-health professional's clinical evaluation.
You can find detailed information about both scales on the BAI page and the GAD-7 page.
