DESCRIPTION (provided by applicant): Latino adolescents, especially those living in Puerto Rico, are at high risk for HIV/AIDS, other sexually transmitted infections (STIs), and unintended pregnancies. A web-based parent communication intervention provides an opportunity to benefit adolescents by providing additional support for safer sex decisions, and to increase parents' involvement in sexual health by decreasing barriers that keep them from participating in these interventions. The purpose of this proposed study is to evaluate a brief, theoretically informed, culturally appropriate, and linguistically tailored web-based parental communication program, Cu¿dalos ("Take care of them"), designed to improve parent-adolescent sexual communication and reduce adolescent sexual risk behavior. Recent findings from an R21 RCT testing a brief computer-based version of the Cu¿dalos program indicated that the program increased parent-adolescent general communication and sexual risk communication with English and Spanish speaking U.S. Latinos.7 In this proposed study, we plan to modify the Cu¿dalos intervention by changing to a web-based format, increasing the amount of content related to sexual communication and adding a module on HIV/AIDS stigma. In this RCT, we will recruit parents (n=680) and one of their adolescents (n=680) from community-based agencies in Puerto Rico, and will be randomly assigned to receive either the parent-based Cu¿dalos intervention or a web-based health promotion control condition. Parents and adolescents will complete measures at pre-intervention and at 3-(parents only), 6-, and 12-month follow-ups. We will address the five following specific aims: 1) Does the Cu¿dalos intervention increase parents' comfort with, as well as the amount of, communication with adolescents and decrease stigma at 3-,6-, and 12- month follow-ups as compared to the general health promotion control intervention; 2) Does the Cu¿dalos intervention decrease self-reported adolescent intercourse and unprotected intercourse at the follow-ups as compared to the general health promotion control intervention; 3) Do theory-based variables (attitudes, subjective norms, perceived behavioral control, intentions) mediate the intervention effects of Cu¿dalos on parents' communication with their adolescents; 4) Are the effects of the Cu¿dalos intervention on adolescent sexual behavior and parent-adolescent communication moderated by individual (adolescents: sexual experience, gender, age, stigma; parents: gender, age computer access/experience, frequency and time engaged in the program), and microsystem (adolescents: parent-adolescent communication) variables; and 5) Puerto Rican and Latino youth, the lack of culturally and linguistically effectiv interventions for Latino parents and adolescents, and the absence of web-based interventions for Latinos. If the program is efficacious, the web-based format will accelerate the translation of this program into public health practice and will be an important contribution in supporting safe adolescent sexual health behaviors. Is the intervention cost-effective? This study addresses existing disparities in sexual health outcomes among PUBLIC HEALTH RELEVANCE: Results from this study will provide an important resource to parents and adolescents to support adolescents' safer sex decisions. Results from testing and using a web-based format will provide important information for the development of future parent-adolescent sexual risk reduction programs and health related technology based interventions for this and other underserved populations.

描述（由申请人提供）：拉丁裔青少年，尤其是居住在波多黎各的青少年，感染艾滋病毒/艾滋病、其他性传播感染 (STI) 和意外怀孕的风险很高。基于网络的家长沟通干预措施提供了一个机会，通过为安全性行为决策提供额外支持来使青少年受益，并通过减少阻碍父母参与这些干预措施的障碍来增加父母对性健康的参与。这项拟议研究的目的是评估一个简短的、理论丰富的、文化上适当的、语言定制的基于网络的家长沟通计划，Cu¿dalos（“照顾他们”），旨在改善父母与青少年的性沟通并减少青少年的性危险行为。 R21 随机对照试验的最新结果表明，该计划增加了与讲英语和西班牙语的美国拉丁裔的父母与青少年的一般沟通和性风险沟通。 7 在这项拟议的研究中，我们计划通过更改为基于网络的格式、增加与性沟通相关的内容量以及添加有关艾滋病毒/艾滋病耻辱的模块来修改库达洛斯的干预措施。在这项随机对照试验中，我们将从波多黎各的社区机构招募父母（n=680）和他们的一名青少年（n=680），并将被随机分配接受基于父母的 Cu¿dalos 干预或基于网络的健康促进控制条件。家长和青少年将在干预前以及 3 个月（仅限家长）、6 个月和 12 个月的随访时完成措施。我们将实现以下五个具体目标： 1) 与一般健康促进控制干预措施相比，库达洛斯干预措施是否会增加父母与青少年沟通的舒适度和沟通量，并减少 3、6 和 12 个月随访时的耻辱感？ 2) 与一般健康促进控制干预措施相比，Cucdalos 干预措施是否减少了随访时自我报告的青少年性行为和无保护性行为？ 3）基于理论的变量（态度、主观规范、感知行为控制、意图）是否介导了Cucdalos对父母与青少年沟通的干预效果？ 4) 库达洛斯干预对青少年性行为和父母与青少年沟通的影响是否受到个人（青少年：性经历、性别、年龄、耻辱；父母：性别、年龄、计算机访问/经验、参与该计划的频率和时间）和微系统（青少年：父母与青少年沟通）变量的调节； 5) 波多黎各和拉丁裔青年，缺乏针对拉丁裔父母和青少年的文化和语言上有效的干预措施，以及缺乏针对拉丁裔的基于网络的干预措施。如果该计划有效，基于网络的格式将加速翻译 该计划将纳入公共卫生实践，并将为支持青少年安全性健康行为做出重要贡献。干预是否具有成本效益？这项研究解决了性健康结果中现有的差异 公共卫生相关性：这项研究的结果将为父母和青少年提供重要资源，以支持青少年做出更安全的性行为决定。测试和使用基于网络的格式的结果将为未来制定父母-青少年性风险降低计划以及针对这一人群和其他服务不足人群的基于健康相关技术的干预措施提供重要信息。
