HIV/STD Prevention for Young Adults Online

描述（由申请人提供）：该提案旨在利用青少年互联网使用来促进安全套的使用，包括（1）为期一年的形成阶段，以评估青少年（即，18至24岁之间）对网页设计的偏好，并根据社会认知理论（SCT）和计划行为理论（TPB）开发最先进的、基于网络的定制信息，以促进安全套的使用;（2）一项随机对照试验（RCT），以评估基于网络的定制信息对青年安全套使用的效果。 在最初的6个月里，研究人员将与18至24岁的年轻人进行反复的焦点小组，以产生，测试和修改定制的安全套使用信息的想法。同时，焦点小组和6个月后，调查人员将与专家网页设计师，翻译设计偏好到多个互联网网页。在项目的第13个月到第40个月，我们将在互联网上进行一项随机对照试验。参加丹佛大都会地区丹佛健康或计划生育诊所的18至24岁的青年将被招募参加这项研究。他们首先将完成（在诊所环境中）一个在线的，自我管理的安全套使用结果的预期，规范，自我效能和做法的基线评估。 然后将受试者随机（通过计算机）分配至两个研究组之一。在第一组（对照组）中，参与者将被引导到一个网页，上面有关于避孕套使用的一般教育信息。第二个分支（有针对性的干预）将引导参与者进入网页，在那里他们将收到有针对性的反馈，以提高对安全套使用的积极预期结果、安全套使用规范、安全套谈判的自我效能和安全套使用的自我效能，其形式是由榜样提供有针对性的信息。所有参与者将被要求返回互联网网站两次-一个月的助推器接触的信息，和三个月的后续风险评估。这些后续访问可以在参与者可以访问互联网的任何地点进行。通过这项调查，我们将了解是否安全套的结果预期，规范和自我效能感的影响量身定制的互动信息，是否与非主要合作伙伴的安全套使用量身定制的互动信息。

DESCRIPTION (provided by applicant): This proposal is designed to capitalize on youth Internet use to promote condom use, incorporating (1) a one-year formative phase to assess youth (i.e., between 18 and 24 years old) preferences for web design and to develop state-of-the- art, web-based tailored messages promoting condom use based on Social Cognitive Theory (SCT) and the Theory of Planned Behavior (TPB); and (2) a randomized controlled trial (RCT) to assess the efficacy of web-based tailored messages on condom use among youth. During the first 6 months, investigators will conduct iterative focus groups with 18-to 24-year-olds to generate, test, and modify ideas for tailored condom use messages. Simultaneous to the focus groups and for 6 months thereafter, investigators will work with expert web designers, to translate design preferences to multiple Internet web pages. In months 13 through 40 of the project, we will implement a randomized controlled trial that will take place on the Internet. Youth between the ages of 18 and 24 who attend Denver Health or Planned Parenthood clinic sites in the Denver metropolitan area will be recruited to participate in the study. They first will complete (in the clinic setting) an online, self-administered baseline assessment of condom-use outcome expectations, norms, self-efficacy and practices. Participants will then be randomized (by computer) to one of two study arms. In the first arm (control), participants will be directed to a web page with generic didactic messages about condom use. The second arm (tailored intervention) will direct participants to web pages where they will receive tailored feedback to increase positive outcome expectancies towards condom use, condom use norms, self-efficacy for condom negotiation, and self-efficacy for condom use in the form of tailored messages delivered by role models. All participants will be asked to return to the Internet site two times--at one month for a booster exposure to messages, and three months for a follow-up risk assessment. These follow-up visits can occur at any location where the participant can access the Internet. Through this investigation we will discern whether condom outcome expectancies, norms and self-efficacy are affected by tailored interactive messages and whether condom use with non-main partners is affected by tailored interactive messages.
