近年来，虚拟现实已成为与健康相关的教育和培训的创新工具。虚拟现实的诸多好处之一是，当真实的环境可能很危险时，新手用户有机会在安全的环境中无人监督地参与。然而，如果虚拟世界中的行为与真实的世界中的行为有效地匹配，则虚拟环境仅对健康相关的研究有用。本研究旨在测试沉浸式，交互式虚拟行人环境的有效性。招募了102名儿童和74名成年人的样本，在虚拟环境和相同的真实的环境中完成模拟过马路。在儿童和成人样本中，通过虚拟和真实的世界中的行为之间的显著相关性来证明结构效度。结果还表明，通过发展差异的行为结构效度;收敛效度显示家长报告的儿童气质和行为之间的相关性在虚拟世界中的内部可靠性的各种措施的行人安全在虚拟世界中;和面子效度，作为衡量用户的自我报告的感知现实在虚拟世界中。我们讨论了其他虚拟环境的可推广性问题，以及虚拟现实应用于理解和预防儿科行人受伤的影响。(c)2008爱思唯尔有限公司保留所有权利。
In recent years, virtual reality has emerged as an innovative tool for health-related education and training. Among the many benefits of virtual reality is the opportunity for novice users to engage unsupervised in a safe environment when the real environment might be dangerous. Virtual environments are only useful for health-related research, however, if behavior in the virtual world validly matches behavior in the real world. This study was designed to test the validity of an immersive, interactive virtual pedestrian environment. A sample of 102 children and 74 adults was recruited to complete simulated road-crossings in both the virtual environment and the identical real environment. In both the child and adult samples, construct validity was demonstrated via significant correlations between behavior in the virtual and real worlds. Results also indicate construct validity through developmental differences in behavior; convergent validity by showing correlations between parent-reported child temperament and behavior in the virtual world; internal reliability of various measures of pedestrian safety in the virtual world; and face validity, as measured by users' self-reported perception of realism in the virtual world. We discuss issues of generalizability to other virtual environments, and the implications for application of virtual reality to understanding and preventing pediatric pedestrian injuries.
