项目摘要

Abstract HIV disproportionately impacts minority adolescents, and most of them have neither undergone HIV testing and counseling (HTC) nor know their status. Adolescence is a "window of opportunity" to intervene with HIV behavior change interventions. Challenges to implementing and disseminating some effective HIV prevention programs in adolescents may limit their impact. To address these challenges, innovative digital technologies can be used as interventions to improve health-related behaviors. They meet adolescents "where they are at," are engaging, provide more consistent fidelity to the intervention, and are easier to disseminate, leading to potentially greater reach at a lower cost. Therefore, the goal of this proposal is to build on the work completed with a Phase I project to further adapt an existing iPad-based HIV prevention intervention with demonstrated efficacy, PlayForward: Elm City Stories (developed for adolescents aged 11-14 and focused on sexual risk reduction) to create a new intervention focused on promoting access to and uptake of HTC in adolescents, aged 14-16. In the original PlayForward, participants create a virtual character they use to travel through life, facing challenges and making decisions that bring different risks, benefits, and consequences. The participants can see how their actions influence their future. The intervention involves a series of realistic stories representing risky situations faced by adolescents in middle or high school, and participants successfully resolve each story to acquire "senses" and "powers." The subsequent Phase I study adapted the intervention for a greater focus on HTC with enhanced storylines and conducted a pilot study that demonstrated efficacy in increasing actual HTC, intentions, and knowledge. For the proposed Phase II study, we will conduct additional formative work with focus groups, and our team of product developers and researchers will expand on the content and scope of the intervention while translating the intervention to a web-based platform. We will move towards commercialization of the digital intervention by working with implementation and marketing partners. We will evaluate the adapted intervention in a randomized controlled trial with 296 racial/ethnic minority adolescents, determining its efficacy as a web-based intervention for impacting their intention to seek HTC, actual obtaining of HTC, and knowledge about HIV/AIDS and testing. They will interact with the intervention for 2 hours per week for 6 weeks, and standardized assessment data will be collected at baseline, 6 weeks, 3 and 6 months. Given the compelling evidence supporting the efficacy of technology in health promotion and disease prevention, and their increased access, fidelity, and potential cost-effectiveness, this proposal holds the promise of an effective, engaging, tailored, and highly accessible prevention intervention with the potential for greater sustainable dissemination and considerable impact on this vulnerable population of adolescents.

抽象的艾滋病毒对少数族裔青少年的影响尤为严重，他们中的大多数都没有接受过艾滋病毒检测和咨询（HTC）也不知道他们的状况。青春期是干预艾滋病毒的“机会之窗” 行为改变干预措施。实施和传播一些有效的艾滋病毒预防措施面临的挑战针对青少年的计划可能会限制其影响。为了应对这些挑战，创新的数字技术可用作改善健康相关行为的干预措施。他们与青少年“在他们所在的地方”会面，具有吸引力，为干预提供更一致的保真度，并且更容易传播，从而导致可能以更低的成本实现更大的覆盖范围。因此，该提案的目标是在已完成的工作的基础上第一阶段项目旨在进一步调整现有的基于 iPad 的艾滋病毒预防干预措施，并已证实功效、PlayForward：Elm City Stories（为 11-14 岁青少年开发，重点关注性风险）减少）制定一项新的干预措施，重点是促进青少年获得和吸收 HTC， 14-16岁。在最初的 PlayForward 中，参与者创建一个虚拟角色，用于穿越人生，面对挑战并做出带来不同风险、收益和后果的决策。参加者可以看到他们的行为如何影响他们的未来。干预涉及一系列现实故事代表初中或高中青少年面临的危险情况，并且参与者成功解决每个故事以获得“感官”和“力量”。随后的第一阶段研究调整了干预措施为了更加关注具有增强故事情节的 HTC，并进行了一项试点研究，该研究证明了在增加实际的 HTC、意图和知识。对于拟议的第二阶段研究，我们将进行额外的研究与焦点小组的形成性工作，我们的产品开发人员和研究人员团队将扩展干预的内容和范围，同时将干预转化为基于网络的平台。我们会搬家通过与实施和营销合作伙伴合作，实现数字干预的商业化。我们将在一项涉及 296 名少数族裔的随机对照试验中评估调整后的干预措施青少年，确定其作为基于网络的干预措施的有效性，以影响他们寻求 HTC 的意图，实际获得HTC，以及有关艾滋病毒/艾滋病和检测的知识。他们将与干预措施互动每周 2 小时，持续 6 周，并在基线、第 6 周、第 3 周和第 3 周收集标准化评估数据 6个月。鉴于有令人信服的证据支持技术在健康促进和该提案认为，疾病预防及其增加的可及性、保真度和潜在的成本效益承诺提供有效、有吸引力、量身定制且易于使用的预防干预措施，具有潜在的潜力以便更可持续地传播并对青少年这一弱势群体产生重大影响。
