互联网的使用在撒哈拉以南非洲地区正在增长。计算机和互联网在减少与艾滋病毒相关的风险行为方面的有效性在美国的证据尚未在非洲得到复制。我们描述了一个基于互联网的艾滋病预防计划在乌干达的中学生，称为CyberSenga的发展，可用性和可导航性测试。在这项工作中，我们使用了四个数据收集活动，包括观察（a）计算机技能和（B）导航，（c）焦点小组讨论，（d）现场评估，以记录程序内容的理解和可用性。我们记录了学生的有限技能，但具有基本计算机技能的年轻人能够在教学后浏览该程序。青少年对互动性较强的活动最感兴趣。现场测试说明了在程序交付期间使用独立电源的重要性。这项工作表明，在非洲提供基于互联网的健康促进内容需要注意用户的准备和识字，带宽，互联网连接和电力。
Use of Internet is growing in Sub Saharan Africa. Evidence of computer and Internet effectiveness for reduction in risk behaviors associated with HIV shown in U.S. settings has yet to be replicated in Africa. We describe the development, usability and navigability testing of an Internet-based HIV prevention program for secondary school students in Uganda, called CyberSenga. For this work, we used four data collection activities, including observation of (a) computer skills and (b) navigation, (c) focus group discussions, and (d) field assessments to document comprehension and usability of program content. We document limited skills among students, but youth with basic computers skills were able to navigate the program after instruction. Youth were most interested in activities with more interaction. Field-testing illustrated the importance of using a stand-alone electrical source during program delivery. This work suggests delivery of Internet-based health promotion content in Africa requires attention to user preparedness and literacy, bandwidth, Internet connection, and electricity.
