Agoraphobia is not merely anxiety about a single situation. Individuals with agoraphobia experience significant anxiety in at least two of the following situations:

* Using public transportation (e.g., taxis, buses, trains, boats, airplanes)
* Being in open spaces (e.g., parking lots, marketplaces, bridges)
* Being in enclosed spaces (e.g., elevators, theaters, cinemas)
* Standing in lines or being in crowds
* Being outside the home alone

To aid in diagnosis, your doctor will likely ask a series of questions. These may include, but are not limited to:

* What symptoms are you experiencing that concern you?
* When did you first notice these symptoms?
* In which situations do your symptoms become most severe?
* What factors seem to increase or decrease the intensity of your symptoms?
* Do you avoid any situations or places due to fear that they might trigger your symptoms?
* How do your symptoms affect your social life?
* Have you been diagnosed with any medical conditions?
* Have you previously received treatment for psychological conditions?
* Have you ever considered self-harm?
* Do you use alcohol or recreational drugs? If so, how often?

The diagnosis of agoraphobia typically relies on:

* An assessment of your signs and symptoms.
* A comprehensive discussion with your doctor.
* A thorough examination to rule out other conditions that could cause your symptoms.
* The diagnostic criteria for agoraphobia as listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association, also assist in the diagnostic process.
