Cognitive deficits have been shown to increase the likelihood of relapse in individuals with substance use disorders (SUD). As such, cognitive training programs are important interventions for this population. In this study, we describe the development and test the usability of a virtual reality (VR)-based cognitive training program for individuals with SUD - VRainSUD. A total of 17 patients receiving inpatient treatment for SUD at an Addiction Treatment Center agreed to participate in the study. Participants completed 9 tasks designed to test the platform's usability. The key performance indicators (e.g., time to complete the task) as well as any relevant observations were recorded. Finally, each participant completed a brief survey and the Post-Study System Usability Questionnaire (PSSUQ). VRainSUD was considered easy and pleasant to use but additional instructions were required on certain cognitive training tasks. The total PSSUQ score confirmed an overall high level of satisfaction concerning the platform's usability (2.72 ± 1.92). Among the three subscales, system usefulness presented the most satisfactory score (1.76 ± 1.37) and information quality presented the least satisfactory score (3.00 ± 1.95). Changes were made to the platform to improve the on-screen information and instructions. Overall, participants showed interest in integrating VRainSUD into their standard treatment. Despite limited prior VR experience, they quickly adapted to the controllers and navigation. VRainSUD can be a potentially successful add-on to SUD treatment.
认知缺陷已被证明会增加物质使用障碍（SUD）患者复发的可能性。因此，认知训练项目是针对这一人群的重要干预措施。在本研究中，我们描述了一种基于虚拟现实（VR）的针对SUD患者的认知训练项目VRainSUD的开发过程，并测试了其可用性。共有17名在戒毒治疗中心接受住院治疗的SUD患者同意参与该研究。参与者完成了9项旨在测试该平台可用性的任务。记录了关键性能指标（如完成任务的时间）以及任何相关观察结果。最后，每位参与者完成了一份简短的调查问卷和研究后系统可用性问卷（PSSUQ）。VRainSUD被认为使用起来简单且令人愉快，但在某些认知训练任务上需要额外的指导。PSSUQ总分证实了对该平台可用性的总体高度满意度（2.72±1.92）。在三个子量表中，系统有用性得分最令人满意（1.76±1.37），信息质量得分最不令人满意（3.00±1.95）。对该平台进行了改进，以提高屏幕上的信息和指导。总体而言，参与者对将VRainSUD纳入其标准治疗表现出兴趣。尽管之前的VR经验有限，但他们很快适应了控制器和导航。VRainSUD可能是SUD治疗中一个潜在成功的附加疗法。
