Abstract

Introduction/objective: Treatment results of anorexia nervosa (AN) are modest, with fear of weight gain being a strong predictor of treatment outcome and relapse. Here, we present a virtual reality (VR) setup for exposure to healthy weight and evaluate its potential as an adjunct treatment for AN.

Methods: In two studies, we investigate VR experience and clinical effects of VR exposure to higher weight in 20 women with high weight concern or shape concern and in 20 women with AN.

Results: In study 1, 90% of participants (18/20) reported symptoms of high arousal but verbalized low to medium levels of fear. Study 2 demonstrated that VR exposure to healthy weight induced high arousal in patients with AN and yielded a trend that four sessions of exposure improved fear of weight gain. Explorative analyses revealed three clusters of individual reactions to exposure, which need further exploration.

Conclusions: VR exposure is a well-accepted and powerful tool for evoking fear of weight gain in patients with AN. We observed a statistical trend that repeated virtual exposure to healthy weight improved fear of weight gain with large effect sizes. Further studies are needed to determine the mechanisms and differential effects.

虚拟现实暴露于健康体重的身体是一种有希望的神经性厌食症辅助治疗。

简介/目的:神经性厌食症(AN)的治疗效果一般，对体重增加的恐惧是治疗结果和复发的一个强有力的预测因素。在这里，我们提出了一个虚拟现实(VR)设置暴露于健康体重，并评估其作为an辅助治疗的潜力。方法:在两项研究中，我们调查了20名高度体重或身材担忧的女性和20名AN女性的VR体验和VR暴露于更高体重的临床效果。结果:在研究1中，90%的参与者(18/20)报告了高度兴奋的症状，但口头表达了低到中等程度的恐惧。研究2表明，VR暴露在健康体重下会引起AN患者的高唤醒，并产生了一种趋势，即四次暴露可以改善对体重增加的恐惧。探索性分析揭示了三组个体对暴露的反应，这需要进一步的探索。结论:VR暴露是引起AN患者体重增加恐惧的一种被广泛接受的强大工具。我们观察到一种统计趋势，即重复虚拟暴露于健康体重的环境中，可以改善对体重增加的恐惧，而且效果显著。需要进一步的研究来确定其机制和差异效应。
