How Does the Beck Anxiety Inventory Work?

Developed by Dr. Aaron T. Beck, and published first in 1988, the Beck Anxiety Inventory is a common tool used by mental health practitioners to assess someone’s level of anxiety. It consists of 21 questions, ranging on a scale from 0 to 3 that aim to gauge a person’s anxiety symptoms. But, like any mental health tool, it’s only as useful as the outcomes it eventually leads to.

In this article, we’ll look at why the BAI was introduced, how it’s used in practice, its limits, and how it can impact those on a self diagnosis journey when it comes to their mental health.

Origins and Development

In developing the Beck Anxiety Inventory, the goal was to create a tool that could differentiate between anxiety and depression, two conditions that often appear together—or, in medical jargon, are co-morbid. While the BAI is copyrighted, versions of the document are easily accessible online. There is also research confirming its validity that has spanned more than thirty years.

Jenna DiLossi, PsyD LPC, co-founder of the Center for Hope and Health and clinical presenter for non-profit Minding Your Mind, said that, in her practice, she regularly uses both the anxiety and depression screeners.

Rachel Goldberg, MS, LMFT, has a different approach. She says that in her counseling practice, a Beck Anxiety Inventory score is something clients (in her case, often those looking for support with an eating disorder, postpartum mental health concerns, or who are navigating infertility) come in with, rather than something they are given by her.

“If a person goes into their doctor after giving birth, and they have their six weeks checkup, the doctor might hand them that Beck Inventory. And if the score is a little bit higher than what they would perceive as normal, they may send that to me with the referral. Then I have an idea of where I'm starting with that client.”

The Inventory and Its Limitations

The BAI consists of 21 questions where you are meant to list, on a scale from 0-3, how much different symptoms have affected you in the last week. Zero is not at all, Three is a lot. Questions include physical symptoms, like dizziness and indigestion, as well as broader ranging symptoms like a very present fear of death or an inability to relax.

While the scoring parameters have shifted over time, the higher the number, the more anxious you are assumed to be. From there, practitioners can sort you into mild, moderate, or severe anxiety.

The inventory does come with its own drawbacks. Researchers have noted that a lot of the symptoms listed allow a practitioner to hone in on physical symptoms more than they do cognitive ones. That’s something that DiLossi sees in her own practice.

DiLossi says that because these physiological symptoms are heavily connected with events like panic attacks, someone with a different presentation of their anxiety might be missed by the BAI. 

“A person who, for example, can't make decisions, struggles with decisions, laments over the best possible option. Or, people who are people pleasers and can't really tolerate if someone doesn't like them, a lot of that is still rooted in anxiety. And a measure like this doesn't quite capture that.”

Still, the BAI is seen as a significant diagnostic and treatment tool that is commonly used by primary care physicians. The inventory has been translated into a number of different languages and has informed diagnostic tools in countries like Korea.

Self Diagnosis and Interpretation

As with any tool that has become broadly available and discussed, including by telehealth providers like BetterHelp, the BAI does exist in a world where self diagnosis is prevalent. Goldberg says that, when it comes to the BAI, it can be a useful tool to start off with, and to track symptoms over time for insurance purposes, but that it’s not something people usually just stumble upon.

“...Usually someone who's seeking out that kind of test already knows they have anxiety. It's very rare that they randomly take this test unless their friend just hands it to them. They already know something's up and maybe they're just trying to get a feel for how high on the anxiety scale they are.”

Her advice is to seek out supports from professionals and to “take it with a grain of salt”  if the results feel as if they are entirely confirming or denying that you’re anxious.
