Pedestrian injury is a leading cause of injury-related mortality for children. This pilot randomized controlled trial tested the efficacy of a training program to teach where and how to cross safely.
Using fully immersive virtual reality technology, 142 children 7-10 years of age were recruited, with 130 completing crossing measures before (pretest) and immediately after (posttest) training. Training comprised 1.5 hr, was tailored to each child's performance over trials, and focused on either where to cross (n = 44 children completed testing) or how to cross safely (n = 43); corresponding control groups comprised 22 and 21 children, respectively. Following training, children in the intervention groups completed additional tasks to test conceptual knowledge and generalization of learning. Children in the control groups spent the same time as those in training groups but played a video game that used the same game controller but provided no training in street crossing.
The primary outcomes were errors in crossing at posttest, controlling for pretest error scores. Children in the intervention group made from 75% to 98% fewer errors at posttest than control children for all pedestrian safety variables related to where and how to cross safely, with effect sizes (incidence rate ratios) varying between 0.02 and 0.25. They also showed a generalization of what they had learned and applied this knowledge to novel posttraining situations.
Training within a virtual pedestrian environment can successfully improve children's conceptual understanding and crossing behaviors for both where and how to cross streets safely.
行人伤害是导致儿童与伤害相关死亡的主要原因。本试点随机对照试验测试了一项培训计划的效果,该计划旨在教授儿童如何安全地在何处以及如何过马路。
使用全沉浸式虚拟现实技术,招募了 142 名 7-10 岁的儿童,其中 130 名在培训前(前测)和培训后(后测)完成了过马路测试。培训包括 1.5 小时,针对每个孩子的表现进行定制,并侧重于过马路的位置(n=44 名儿童完成了测试)或安全过马路的方式(n=43 名儿童);相应的对照组由 22 名和 21 名儿童组成。培训后,干预组的儿童完成了额外的任务,以测试概念知识和学习的泛化。对照组的儿童花费与训练组相同的时间,但玩了一个使用相同游戏控制器但不提供过马路培训的视频游戏。
主要结果是后测时的过马路错误,控制了前测错误分数。与所有与安全过马路的位置和方式相关的行人安全变量相比,干预组的儿童在后测时的错误比对照组儿童减少了 75%至 98%,效果大小(发病率比)在 0.02 到 0.25 之间。他们还表现出了所学知识的泛化,并将这些知识应用于新的培训后情境。
在虚拟行人环境中进行培训可以成功提高儿童对安全过马路的位置和方式的概念理解和过马路行为。
