项目摘要

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.

自杀是青少年第二大死亡原因，遭受网络欺凌的青少年是青少年的两倍网络欺凌 (CB) 可能会表现出自杀想法和行为，就像那些没有受到网络欺凌 (CB) 的人一样。与自杀意念密切相关，这是一种快速波动的现象，这表明需要对 CB 实例进行近端干预以降低自杀风险公共健康需要减少自杀。遭受网络欺凌的青少年，尤其是服务不足的青少年（即少数民族青少年）面临的风险然而，目前的干预措施还不够。他们满足服务不足的年轻人的需求和在情绪高涨时进行干预的能力有限该以患者为导向的职业发展奖（K23）的目的是提供脆弱性。申请人是一名行为健康科学家和临床社会工作者，具有弥补差距所需的技能通过利益相关者知情和经验驱动的数字化，在CB干预和自杀预防之间进行研究为了实现这一长期目标，将提供多学科培训计划。申请人具有以下方面的专业知识：(1) 在线临床试验的设计、实施和分析；(2) 理论、研究、 (3) 改善服务不足的方法青少年利用以人为本的设计 (HCD) 和简短的动机进行数字干预申请人将在强大的多学科环境中接受辅导并取得成就。青少年自杀预防、CB 研究、HCD 和在线临床试验领域的专家。培训和课程将推进临床试验设计和实施方面的培训（道德和社交媒体- 基于招聘）和分析（机器学习的中介和调节分析和评估[ML] 临床试验模型）、CB 研究和提高参与度的方法（HCD 和动机采访）补充研究计划将重点关注 imHere4U（一个刚刚推出的项目）的开发和测试。时间，针对网络欺凌青少年的自杀预防干预基于表明可接受性的试点数据。为了针对遭受网络欺凌的青少年、家长和专业人士开展 imHere4U 活动，我们提出了三个目标 1：遭受网络欺凌的青少年（N=20；>35% 服务不足）将参与迭代设计，以优化数字化目标 2：最近遭受网络欺凌的青少年（N=80；>35% 服务不足）将参与在线 RCT 测试 imHere4U 加在线互动问卷与单独问卷调查的比较：我们将研究使用机器学习算法向青少年提供支持性反馈的可行性这项试验将测试imHere4U的可行性和初步功效，至关重要。后续 R01 应用程序的数据，以在更大的样本和传播中测试 imHere4U 的功效这项调查的结果预计将产生有效的干预措施，填补关键的空白。通过在CB发生的时间和地点进行干预来预防青少年自杀风险，从而缩小服务提供方面的差距。
