Suicide is the second leading cause of death among adolescents, and youth who are cyberbullied are twice as likely to exhibit suicidal thoughts and behaviors as those who are not cyberbullied. Cyberbullying (CB) is strongly associated with suicidal ideation, a phenomenon known to fluctuate rapidly, which suggests need to intervene proximally to instances of CB to reduce suicide risk. There is public health need to reduce suicide risk among cyberbullied adolescents, especially underserved adolescents (i.e., youth from minority backgrounds) who face higher rates of CB and suicidal thoughts and behavior. Yet, current interventions are limited in their capacity to meet the needs of underserved youth and to intervene in moments of high vulnerability. The purpose of this Mentored Patient-Oriented Career Development Award (K23) is to provide the applicant, a behavioral health scientist and clinical social worker, with the skills necessary to bridge the gap between CB intervention and suicide prevention with stakeholder-informed and empirically driven digital interventions for adolescents. To accomplish this long-term goal, a multidisciplinary training plan will provide the applicant with expertise in: (1) design, conduct, and analysis of online clinical trials; (2) theory, research, and methods of adolescent CB assessment and intervention; and (3) methods of enhancing underserved adolescents’ utilization of digital interventions using human centered design (HCD) and brief motivational interventions. The applicant will receive mentoring in a strong multidisciplinary environment with accomplished experts in the fields of adolescent suicide prevention, CB research, HCD, and online clinical trials. Formal training and coursework will advance training in clinical trial design and conduct (ethics and social media- based recruitment), and analysis (mediation and moderation analysis and evaluation of machine learning [ML] models for clinical trials), CB research, and methods for enhancing engagement (HCD and motivational interviewing). A complementary research plan will focus on development and testing of imHere4U, a just-in- time, suicide prevention intervention for cyberbullied adolescents. Based on pilot data suggesting acceptability of imHere4U among cyberbullied youth, parents, and professionals, we propose three aims. Aim 1: Cyberbullied adolescents (N=20; >35% underserved) will participate in iterative design to optimize a digital product for their needs. Aim 2: Recently cyberbullied adolescents (N=80; >35% underserved) will participate in an online RCT testing imHere4U plus Questionnaires of online interactions vs. Questionnaires alone. Aim 3: We will examine the feasibility of using a ML algorithm to deliver feedback to adolescents on their supportive and bullying online interactions. This trial will test the feasibility and preliminary efficacy of imHere4U, essential data for a subsequent R01 application to test imHere4U’s efficacy within a larger sample and dissemination outcomes. Results from this investigation are expected to lead to an efficacious intervention that fills a critical gap in service delivery by intervening when and where CB occurs to prevent adolescent suicide risk.

自杀是青少年死亡的第二大原因，而受到网络欺凌的青少年是青少年死亡的两倍。 可能会表现出自杀的想法和行为，因为那些没有被网络欺凌的人。网络欺凌（CB） 与自杀意念密切相关，这种现象波动迅速，这表明需要 在CB病例附近进行干预，以降低自杀风险。公共卫生需要减少自杀 网络欺凌青少年的风险，特别是服务不足的青少年（即，少数民族青年 他们面临着更高的CB和自杀想法和行为的比率。然而，目前的干预措施 他们满足得不到充分服务的青年的需要和在高风险时刻进行干预的能力有限， 易损性.这个指导病人为导向的职业发展奖（K23）的目的是提供 申请人是一名行为健康科学家和临床社会工作者，具有弥合差距所需的技能 CB干预和自杀预防之间的关系， 对青少年的干预。为了实现这一长期目标，将制定一项多学科培训计划， 申请人在以下方面具有专业知识：（1）在线临床试验的设计，实施和分析;（2）理论，研究， 和青少年CB评估和干预的方法;（3）提高服务不足的方法 青少年使用以人为中心的设计（HCD）和简短的动机数字干预措施 干预措施。申请人将在一个强大的多学科环境中接受指导， 青少年自杀预防、CB研究、HCD和在线临床试验领域的专家。正式 培训和课程将推进临床试验设计和实施方面的培训（伦理和社交媒体- 基于招聘）和分析（中介和适度分析和机器学习的评估[ML] 临床试验模型），CB研究，以及增强参与度的方法（HCD和激励 面试）。一项补充研究计划将侧重于imHere 4U的开发和测试，这是一种刚刚进入市场的产品。 时间，自杀预防干预网络欺凌的青少年。根据表明可接受性的试点数据 imHere 4U在网络欺凌的青少年，家长和专业人士，我们提出了三个目标。目标1： 受网络欺凌的青少年（N=20; >35%服务不足）将参与迭代设计，以优化数字 产品满足他们的需求。目标2：最近被网络欺凌的青少年（N=80; >35%服务不足）将参加 一项在线随机对照试验，测试imHere 4U加在线互动的在线在线互动与单独在线互动。目标3： 我们将研究使用ML算法向青少年提供关于他们支持的反馈的可行性。 和欺凌在线互动。该试验将测试imHere 4U，Essential的可行性和初步疗效 随后的R 01应用程序的数据，以测试imHere 4U在更大样本和传播中的功效 结果。这项调查的结果预计将导致有效的干预，填补了一个关键的 通过干预CB发生的时间和地点，以防止青少年自杀风险，从而缩小服务提供的差距。
