The researchers enlisted 100 volunteers for their study, all of whom had a clinically diagnosed fear of heights but were not receiving treatment for their phobia. The researchers then split the volunteers into two groups. Fifty-one volunteers served as the control, undergoing no treatment, while the other 49 had the opportunity to undergo a two-week-long virtual reality (VR) treatment regimen (47 agreed to the program, and 44 completed it).  The researchers published the results of their trial in the journal The Lancet Psychiatry on Wednesday.

A VIRTUAL COACH. Over the course of the VR treatment program, volunteers used a VR headset to meet with a “virtual coach” for six sessions, each roughly 30 minutes long.

This automated coach started by asking them questions about their fear of heights and telling them facts about their phobia. Next, the coach guided the volunteers through a series of virtual scenarios to help them address their fear.

These ranged from tossing balls over a ledge to rescuing a cat from a tree. At the end of each session, the virtual coach asked each volunteer how they felt.

The coach also encouraged the volunteer to encounter “real-world” heights between sessions. All of the participants in the study filled out questionnaires about the severity of their fear of heights at the beginning of the trial, two weeks later (at the end of the VR treatment program), and again two weeks after that.
