BEHAVIORAL SURVEILLANCE

描述（由申请人提供）：得克萨斯州国家艾滋病毒行为监测（NHBS）项目的目标是通过高危人群的艾滋病毒风险行为数据监测艾滋病毒流行，以指导得克萨斯州当地的艾滋病毒预防计划，并促进国家艾滋病毒行为监测系统的发展。在实施调查之前，将进行形成性研究，使用关键的知情人访谈、焦点小组和人种学评估，以制定当地调查问题，并确定开展实地研究活动的当地地点。德克萨斯州NHBS项目小组将在达拉斯-沃斯堡-阿灵顿大都会统计区达拉斯区的三个成年高危人群（男男性行为者（MSM）、注射毒品使用者（IDU）和高危异性恋者（HET））中开展一项关于艾滋病毒风险行为、获得和利用艾滋病毒预防服务的匿名横断面调查。在三年期项目的每个周期内，将对每个高风险群体的合格参与者进行至少500次调查，调查将酌情采用基于地点的时空抽样和受调查者驱动的抽样方法。此外，中心亦会为自愿及不记名的参加者进行爱滋病病毒测试，以估计每一高危组别的爱滋病病毒阳性率及发病率。所有的调查和艾滋病毒检测都将由一组经过培训的工作人员在一个安全的移动的检测装置（定制的休闲车）中进行。将对研究数据进行分析，并将研究结果分发给社区组织和艾滋病毒社区规划小组，以指导预防资源的分配，并设计和评估预防干预措施。得克萨斯州NHBS还将对当地NHBS系统、其采样系统的质量、效率和有用性以及数据收集方法进行评估，以确保该系统符合项目目标。

DESCRIPTION (provided by applicant): The goal of the Texas National HIV Behavioral Surveillance (NHBS) project is to monitor the HIV epidemic through HIV risk behavior data of high risk groups in order to guide local HIV prevention programs in Texas and contribute to the development of a National HIV Behavioral Surveillance system. Formative research will be conducted prior to implementation of the survey using key informant interviews, focus groups, and ethnographic assessments to develop local survey questions and identify local venues for conducting field research activities. The Texas NHBS project team will conduct an anonymous, cross-sectional survey of HIV risk behaviors, access to and utilization of HIV Prevention services in three adult high risk populations, men who have sex with men (MSM), injecting drug users (IDU) and heterosexuals at risk (HET) in the Dallas Division, Dallas-Fort Worth-Arlington Metropolitan Statistical Area. A minimum of 500 surveys will be completed from eligible participants in each high risk group during each cycle of the three year project using venue based, time-space sampling and respondent driven sampling methodologies as appropriate for the target population. Voluntary and anonymous HIV testing will also be conducted on consenting participants to estimate HIV seroprevalence and incidence of each high risk group. All surveys and HIV testing will be conducted by a team of trained staff in a secure mobile testing unit (customized recreational vehicle). Research data will be analyzed and study findings will be disseminated to community based organizations and HIV community planning groups to guide prevention resource allocation and to design and evaluate prevention interventions. The Texas NHBS will also conduct evaluations of the local NHBS system, the quality, efficiency, and usefulness of its sampling systems and data collection methods to ensure the system is meeting the project goals.
