HIV/STD Prevention for Young Adults Online

说明(申请人提供)：这项建议旨在利用青少年使用互联网推广安全套的使用，包括(1)为期一年的形成阶段，以评估青少年(即18至24岁)对网页设计的喜好，并根据社会认知理论(SCT)和计划行为理论(TPB)开发最先进的、基于网络的量身定制信息，以推广使用安全套；以及(2)随机对照试验(RCT)，以评估在青少年中使用安全套的基于网络的量身定制信息的效果。在最初的6个月中，调查人员将对18至24岁的年轻人进行迭代焦点小组，以生成、测试和修改定制避孕套使用信息的想法。在焦点小组的同时以及之后的6个月里，调查人员将与专业的网页设计师合作，将设计偏好转化为多个互联网网页。在项目的第13个月到第40个月，我们将实施一项随机对照试验，该试验将在互联网上进行。在丹佛大都市区的丹佛健康诊所或计划生育诊所就诊的18岁至24岁的年轻人将被招募参与这项研究。他们首先将完成(在诊所环境中)对避孕套使用结果预期、规范、自我效能和实践的在线自我管理基线评估。然后，参与者将被随机(通过计算机)分配到两个研究小组中的一个。在第一个手臂(对照)中，参与者将被引导到一个网页，其中包含关于使用避孕套的一般说教信息。第二个手臂(定制干预)将引导参与者访问网页，在那里他们将收到定制的反馈，以增加对使用安全套的积极结果预期、避孕套使用规范、避孕套谈判的自我效能以及以榜样传递的定制信息的形式使用避孕套的自我效能。所有参与者将被要求返回互联网网站两次--一个月是为了加强接触信息，三个月是为了后续风险评估。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，我们将了解安全套的预期结果、规范和自我效能是否受到定制互动信息的影响，以及与非主要伴侣的避孕套使用是否受到定制互动信息的影响。

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.
