The intervention group will receive 2 VR exposure interventions, once a week, and each intervention will experience 2 complete flight processes for about 90 minutes each time. A complete flight process includes: (1) waiting for the airport bus at the station, (2) check-in, security check, waiting, and boarding at the airport, (3) taxiing, taking off, cruising, landing, and leaving the aircraft during flight. Among them, the flight process requires the participant to sit on the flight seat, which takes about 24 minutes each time.

A scale assessment and skin electrode and heart rate data collection will be conducted before and after each intervention. The participants' skin electrode and heart rate data will also be collected during the intervention. They will be followed up in the 2nd week after the intervention. Follow-up content includes scale evaluation and safety evaluation.

The control group will receive scale assessments in weeks 1, 2, and 4, and after the waiting period, receive the same VR exposure intervention once a week for 2 weeks as the intervention group.

Virtual reality exposure therapy is a new treatment technology developed in recent years. This technology combines virtual reality technology with traditional exposure therapy, and uses virtual reality technology to present the exposure scenes required for exposure therapy. Therefore, it can break through the limitations of time and space and more intuitively display some things that are difficult to simulate in the treatment room. Scenes do not require the client to undergo treatment through imaginary exposure, thereby increasing the immersion and reality of the treatment. Over the past two decades, numerous studies have explored and proven the effectiveness of virtual exposure therapy.

It was compiled by Van Gerwen et al. in 1999 to assess flight-related anxiety in different situations. It consists of 32 items rated on a 5-point scale from 1 ("Not at all anxious") to 5 ("Extremely anxious"). "), with a total score of 32-160 points. The scale consists of three subscales that assess anticipatory flight anxiety (anxiety that occurs when a person anticipates flying), in-flight anxiety, and generalized flight anxiety, with item numbers of 14, 11, and 7 respectively. This questionnaire has good reliability and validity, has established norms, can be used as a clinical measurement tool for fear of flying, is widely used in clinical practice and research, and is used as the main efficacy indicator.

It was compiled by Van Gerwen et al. in 1999 and is used to measure the symptom pattern of expressing anxiety in flight situations, including a somatic pattern related to physical symptoms and a cognitive pattern related to the cognition of presence of pain, with a total of 18 items. , rated on a 5-point scale from 1 ("not at all") to 5 ("very strongly"), with a total score of 18-90. The questionnaire has good reliability and validity.
