When you’re treating a patient with anxiety symptoms, you may use an assessment tool to support your diagnosis. The Beck Anxiety Inventory is one way to better understand the severity of a client’s anxiety symptoms, so you can determine the best course of treatment.
What is the Beck Anxiety Inventory?
The Beck Anxiety Inventory, or BAI, is a self-report assessment used to rate the severity of someone’s anxiety levels. It asks respondents about common anxiety symptoms over the course of the last week and how much these symptoms have affected them.
The BAI was developed by American psychiatrist Aaron T. Beck in 1988, and it’s been widely used since its inception. Beck also developed the Beck Depression Inventory, a self-report assessment for measuring depression symptoms.
Understanding the structure
The Beck Anxiety Inventory has 21 questions about common anxiety symptoms such as nervousness, face flushing, and dizziness. It asks respondents to rate their symptoms as follows:
- Not at all
- Mildly, but it didn’t bother me much
- Moderately — it wasn’t pleasant at times
- Severely — it bothered me a lot
Each answer on the Beck Anxiety Inventory scale corresponds with a point value from 0-3.
How to interpret the scoring system
Beck Anxiety Inventory scores range from 0-63. The higher the score, in general, the more severe a person’s anxiety will be. Beck Anxiety Inventory scores are grouped as:
- 0-21, Low anxiety: Suggests some anxiety symptoms that may benefit from monitoring or intervention
- 22-35, Moderate anxiety: Reflects clinically significant anxiety that may require therapeutic support or treatment
- 36-63, Severe anxiety: Points to intense, persistent anxiety likely impairing daily functioning and requiring comprehensive therapeutic treatment
Understanding the validity and reliability of the results
The BAI is considered a reliable tool for mental health providers to measure the severity of anxiety symptoms, especially alongside a clinical interview. As the inventory helps clinicians better understand an individual's experience of anxiety, it's also proven to differentiate between clients who experience severe anxiety and those who do not. It also shows high internal consistency, which means each question on the inventory equally measures anxiety and people who take the test get consistent results over a one-week time span.

How to use the Beck Anxiety Inventory in your practice
The Beck Anxiety Inventory can be a useful tool for assessing anxiety. While it’s not a diagnostic tool in and of itself, it can help measure the severity of a client’s anxiety and how their symptoms are impairing their life.
You can use the BAI as part of an initial assessment to gather a baseline of your client’s anxiety symptoms. The assessment can also be helpful for measuring changes in anxiety symptoms over time, so you can adjust your treatment plan if needed. It can be completed and scored on paper or electronically. Many EHRs include common mental health assessments, including the Beck Anxiety Inventory.
Consider using the Beck Anxiety Inventory alongside other well-known anxiety assessment tools, such as the GAD-7, for a more comprehensive picture of your client’s symptoms.
Consider these limitations before using.
As with any assessment, the Beck Anxiety Inventory is not meant to be a diagnostic tool in and of itself. Instead, it can help support a diagnosis and identify changing symptoms along with a clinical assessment conducted by a therapist.
The Inventory also only assesses anxiety symptoms over the last week. It can’t identify a person’s risk factors for anxiety, such as traumatic experiences and a family history of anxiety.
Keep in mind the Beck Anxiety Inventory is a self-assessment, which means clients rate their own symptoms and experiences. Some respondents may have trouble accurately recognizing and reporting their symptoms. Your clinical expertise plays an important role in diagnosing and treating anxiety symptoms.
