Stereoscopic 3D gives the viewer the same shape, size, perspective and depth they would experience viewing the real world and could mimic the perceptual threat cues present in real life. This is the first study to investigate whether an immersive stereoscopic 3D video exposure-based treatment would be effective in reducing fear of spiders. Participants with a fear of spiders (N = 77) watched two psychoeducational videos with facts about spiders and phobias. They were then randomized to a treatment condition that watched a single session of a stereoscopic 3D immersive video exposure-based treatment (six 5-min exposures) delivered through a virtual reality headset or a psychoeducation only control condition that watched a 30-min neutral video (2D documentary) presented on a computer monitor. Assessments of spider fear (Fear of Spiders Questionnaire [FSQ], Behavioral Approach Task [BAT], & subjective ratings of fear) were completed pre- and post-treatment. Consistent with prediction, the stereoscopic 3D video condition outperformed the control condition in reducing fear of spiders showing a large between-group effect size on the FSQ (Cohen's d = 0.85) and a medium between-group effect size on the BAT (Cohen's d = 0.47). This provides initial support for stereoscopic 3D video in treating phobias.
立体 3D 给观看者提供了与他们在现实世界中观察到的相同的形状、大小、视角和深度，并且可以模拟现实生活中存在的感知威胁线索。这是第一项研究，旨在调查基于沉浸式立体 3D 视频暴露的治疗是否会有效减少对蜘蛛的恐惧。有蜘蛛恐惧症的参与者（N=77）观看了两个关于蜘蛛和恐惧症的心理教育视频。然后，他们被随机分配到治疗条件，观看单次基于立体 3D 沉浸式视频暴露的治疗（六个 5 分钟的暴露），通过虚拟现实耳机呈现，或观看仅接受心理教育的控制条件，观看在计算机显示器上呈现的 30 分钟中性视频（2D 纪录片）。在治疗前和治疗后完成对蜘蛛恐惧的评估（蜘蛛恐惧问卷[FSQ]、行为接近任务[BAT]和恐惧的主观评分）。与预测一致，立体 3D 视频治疗条件在降低蜘蛛恐惧方面优于对照组，FSQ 上的组间效应量较大（Cohen's d=0.85），BAT 上的组间效应量中等（Cohen's d=0.47）。这为立体 3D 视频治疗恐惧症提供了初步支持。
