Final answer:
The therapist is using virtual reality exposure therapy to help Brianna with her agoraphobia.
Step-by-step explanation:
The technique Brianna's therapist is using is called virtual reality exposure therapy. This therapy involves using virtual reality to gradually expose individuals to their fears or phobias in a safe and controlled environment. It is often used to treat anxiety disorders, including agoraphobia.
Virtual reality exposure therapy has been found to be effective in helping individuals overcome their fears by gradually desensitizing them to the feared stimuli. The therapist gradually increases the duration and intensity of the exposure to help Brianna re-learn that going out in public is safe and manageable. Several studies have shown the efficacy of virtual reality exposure therapy in treating anxiety disorders, including post-traumatic stress disorder (PTSD) and specific phobias. It provides a unique and immersive experience that allows individuals to confront their fears in a realistic and controlled manner.
