项目摘要

DESCRIPTION (provided by applicant): This proposed project seeks to develop and test the feasibility of a human laboratory and clinically based virtual reality cannabis cue exposure assessment system (VR-CCA) for cannabis abuse and dependence. Traditional assessment methods (cue exposure) involve bringing persons into austere laboratory or clinical environments and using photos, video, paraphernalia or therapist role playing to elicit and assess reactions. While this results in reactions, the inherent lack of ecological validity may limit generalization of traditional cue exposure in treatment programs. Virtual reality exposure (VRE) combines computer graphics with sensory input devices including: tracking devices, visual head mounted displays (HMD), and directional audio designed to immerse a participant in a computer-generated virtual environment. VR-CCA for cannabis would combine the elements of VR with specific drug cues, environments, drug related social interactions, olfactory cues (various scents) and other associated stimuli in the safe, confidential and controlled lab or office setting. VR-CCA combining video images and exposure to complex cues can expand traditional assessment methods (i.e. cue-exposure/reactivity) approaches and offer distinct advantages over traditional approaches. This project will focus on the development of a VR-CCA combining both computer generated and video images depicting cannabis smoking cues (e.g. cannabis cigarettes, pipes, burning joints) and cannabis smoking social interactions (e.g. being offered a cannabis cigarette in a social context). The feasibility of VR-CCA will be tested in an open clinical pilot trial with current cannabis smokers. Twenty cannabis smokers will be exposed to both VR neutral stimuli and VR drug (cannabis) stimuli. Physiological arousal and self-reported craving and mood will be compared between the VR neutral and VR drug (cannabis) stimuli. The aim of this project is to develop and pilot test VR-CCA for cannabis smokers. The long-term goal is to develop and test the VR-CCA, and develop affordable turnkey, VR-CCA systems that will be commercially available to substance abuse programs, individual therapists, hospitals, and drug addiction researchers for assessment and treatment of cannabis and other drugs of abuse.

描述（由申请人提供）：该拟议项目旨在开发和测试人类实验室和基于临床的虚拟现实大麻提示暴露评估系统（VR-CCA）的可行性，以滥用大麻和依赖性。传统的评估方法（提示暴露）涉及将人员带入严峻的实验室或临床环境，并使用照片，视频，用具或治疗师角色扮演的角色扮演和评估反应。尽管这会导致反应，但固有的生态有效性可能会限制治疗计划中传统提示暴露的概括。虚拟现实曝光（VRE）结合了计算机图形和感官输入设备，包括：跟踪设备，视觉头安装显示器（HMD）和旨在将参与者浸入计算机生成的虚拟环境中的方向音频。用于大麻的VR-CCA将在安全，机密和控制的实验室或办公室环境中，将VR的要素与特定的药物提示，环境，与药物相关的社交互动（各种香气）和其他相关刺激结合在一起。结合视频图像和复杂提示的VR-CCA可以扩展传统的评估方法（即提示曝光/反应性）方法，并与传统方法相比提供了明显的优势。该项目将重点介绍VR-CCA的开发，结合了计算机生成的和视频图像，描绘了大麻吸烟提示（例如大麻卷烟，管道，燃烧的关节）和大麻吸烟社交互动（例如，在社交环境中提供大麻香烟）。 VR-CCA的可行性将在目前吸烟者的开放临床试验试验中进行测试。 20名吸烟者将暴露于VR中性刺激和VR药物（大麻）刺激中。在VR中性药物（大麻）刺激之间将比较生理唤醒和自我报告的渴望和情绪。该项目的目的是为吸烟者开发和试生VR-CCA。长期的目标是开发和测试VR-CCA，并开发负担得起的交钥匙，VR-CCA系统，该系统将在药物滥用计划，个人治疗师，医院和药物成瘾研究人员的评估和治疗大麻和其他滥用药物的评估和治疗。
