研究概览
简要总结
The aim of this study is to examine the efficacy of virtual reality exposure therapy (VRET) as a treatment for specific phobia (acrophobia). The study will randomly assign 42 participants with acrophobia to one of two conditions: a) the experimental condition (consisting of 3 sessions of virtual reality exposure) or b) a control condition. Both groups will receive short information session about general principles of exposure therapy before the start of the study. After the end of the study, the waitlist group will be invited to attend the short version (one or two-sessions) of the VRET. Both groups will receive a final follow-up questionnaires 2 months after the last session.

结局指标
主要结局
The IAPT phobia scale-avoidance
时间窗: 2-months Post-Treatment (Controlling for Immediate Post-Treatment Score)
The IAPT phobia scale-avoidance is a single item from the outcome measures administered by the UK National Health Service's IAPT programme (Improving Access to Psychological Therapies). The patient is asked to rate his/her avoidance of heights in daily situations on a scale from 0 (would not avoid it) to 8 (always avoid it).
Visual Height Intolerance Severity Scale (vHISS)
时间窗: 2-months Post-Treatment (Controlling for Immediate Post-Treatment Score)
The vHISS is a 8-item scale assessing the severity of visual height intolerance with additional questions for acrophobia.Raw score range from 0 to 13, where 0 = least severely affected and 13 = most severely affected.
Severity Measure for Specific Phobia-Adult (SMSP-A)
时间窗: 2-months Post-Treatment (Controlling for Immediate Post-Treatment Score)
SMSP-A is a 10-item scale that assesses the severity of specific phobias in individuals aged 18 and older over the past 7 days. Items are scored on a 5-point Likert scale with item scores of 1-4 respectively indicating mild, moderate, severe and extreme severity of specific phobia related distress.
次要结局
- Six-item State-Trait Anxiety Inventory (STAI-6)(Immediately Post-Sessions)
- Subjective Units of Distress Scale (SUDS)(Through study completion, an average of 1 months. During In-Sessions: week 1-3 (reported repeatedly during each session in response to presented exposure situations).)
- Anxiety Hierarchy(Immediately Post-Treatment (Controlling for Baseline Score))
