Thailand (2005): HIV/AIDS TRaC Study among Transgenders in Pattaya First Round

1) To gain comprehensive and detailed data for informing PSI's interventions with transgenders; 2) To segment the population according to consistent condom use with regular partners, consistent condom use with casual partners, and consistent water-based lubricant use; 3) To identify key determinants (OAM Opportunity, Ability and Motivation) associated with each behavior; and 4) To obtain baseline information for monitoring key indicators, behavior change, OAM determinants, and exposure to PSI Thailand's interventions. Respondent-Driven Sampling (RDS) was used to collect data from 400 transgenders aged 15-35 in Pattaya. For inclusion in the study, transgenders must have been living in Pattaya for at least three months and work or socialize in hot zones, which are in North, Central and South Pattaya, at least three nights a week. The self-administered questionnaire covered demographic information, sexual behavior, condom and lubricant use, OAM determinants, and exposure to PSI's interventions. Multivariate analyses were performed to identify significant determinants of condom and water-based lubricant use. Simple frequencies were run on descriptive data to complete the monitoring table.

1) 为支撑PSI针对跨性别群体的干预实践，获取全面详实的基础数据；2) 依据与固定性伴持续使用安全套、与临时性伴持续使用安全套，以及持续使用水性润滑剂的行为表现对人群进行分组；3) 明确与上述各类行为相关的关键决定因素——机会-能力-动机（Opportunity, Ability and Motivation，OAM）；4) 采集基线信息，用于监测关键指标、行为变化、OAM决定因素，以及PSI泰国项目的干预暴露情况。
本研究采用受访者驱动抽样（Respondent-Driven Sampling，RDS）方法，在泰国芭提雅招募了400名年龄介于15至35岁的跨性别者作为研究对象。
纳入本研究的跨性别者需满足以下条件：在芭提雅连续居住至少三个月，且每周至少三个夜晚在芭提雅北部、中部及南部的热点区域工作或参与社交活动。
本次研究使用的自填式调查问卷涵盖人口统计学信息、性行为特征、安全套与润滑剂使用情况、OAM决定因素，以及PSI项目的干预暴露情况。
研究人员通过多变量分析识别出影响安全套及水性润滑剂使用的显著决定因素；同时针对描述性数据开展简单频次分析，以完成监测表格的编制。
