DESCRIPTION (provided by applicant): The objective of the proposed study is to test the effectiveness of virtual reality (VR) based interactive distraction for acute pain management in children. To accomplish this general goal, the proposed series of studies will: 1) Test whether the interactive nature of VR is a critical contributor to its effectiveness as a distractor during an acute laboratory pain experience (cold pressor); 2) Test whether interactive distraction is more effective in reducing cold pressor pain when provided via VR technology than when provided without the use of VR technology; 3) Test the effectiveness of VR distraction with a younger sample of children than has been used in the literature (i.e., a sample that includes 6-8-year-old children in addition to older elementary and middle school aged children); 4) Test whether findings obtained in the laboratory generalize to a clinical population of hematology patients by conducting a pilot test of VR distraction with Hematology-Oncology patients; and 5) Examine the role of child age and child anxiety as possible moderators of treatment outcome. Three studies are proposed. Study 1 tests interactive versus passive VR distraction during a laboratory cold pressor task. Sixty-six children will complete a baseline cold pressor trial and will then be assigned to one of the two experimental distraction conditions or to a control condition for the second cold pressor trial. Study 2 tests interactive distraction with and without VR technology with 90 children undergoing a laboratory cold pressor task. A 3 (experimental group) by 2 (cold pressor trials trials) mixed design similar to Study 1 will be used. In both studies, children are expected to demonstrate improvements in pain tolerance, pain threshold, and perceived pain intensity during the distraction conditions. However, in study 1, interactive VR distraction is expected to be superior to passive VR distraction. In Study 2, interactive distraction with VR is expected to be superior to interactive distraction without VR. Study 3 tests the applicability of VR based interactive distraction to the clinical setting. A pilot sample of children undergoing repeated hematological procedures will receive interactive distraction with and without VR technology in an alternating treatments design. Self report of pain during medical procedures and overt behavioral distress are expected to be lower in both distraction conditions relative to baseline, with the greatest benefits evident when VR technology is used.

描述（由申请人提供）：拟议研究的目的是测试儿童急性疼痛管理的基于虚拟现实（VR）的互动分心的有效性。为了实现这一总体目标，拟议的一系列研究将：1）测试VR的互动性是否是其在急性实验室疼痛体验期间作为干扰物的有效性的关键因素（冷persor）； 2）测试通过VR技术提供的交互式分散注意力是否比不使用VR技术提供的时会更有效地减轻冷压力疼痛； 3）测试VR对年轻儿童样本分散注意力的有效性，而不是文献中使用的（即，除了年龄较大的小学和中学儿童外，还包括6-8岁儿童的样本）； 4）测试实验室中获得的发现是否通过对血液肿瘤患者分心的VR分心进行试验性测试来推广到血液学患者的临床人群； 5）检查儿童年龄和儿童焦虑症的作用是治疗结果的调节剂。提出了三项研究。研究1测试在实验室冷压任务中，交互式与被动VR分散注意力。 66名儿童将完成一项基线冷压力试验，然后将其分配给两个实验干扰条件之一或第二次冷压试验的对照条件。研究2测试与有90名儿童接受实验室冷训练任务的互动分散注意力。将使用类似于研究1的2（冷压试验）的3（实验组）（实验组）。在这两项研究中，预计儿童都将证明疼痛耐受性，疼痛阈值和分心条件下的疼痛强度的改善。但是，在研究1中，交互式VR干扰预计将优于被动VR分散注意力。在研究2中，预计在没有VR的情况下，与VR的互动分散注意力将优于互动分散注意力。研究3测试基于VR的互动分散注意力对临床环境的适用性。接受反复血液学程序的儿童的试验样本将在交替治疗设计中获得有或没有VR技术的互动分散注意力。相对于基准，在两种干扰条件下，医疗程序中的疼痛和公开行为困扰的自我报告预计将较低，当使用VR技术时，最明显的好处。
