Centra America 2013: TRaC study measuring condom use among men at risk in Guatemala, El Salvador, Nicaragua, Costa Rica, Panama and Belize, round 1

1. GOAL OF THE TRaC STUDY The goal of this study is to collect baseline data on the prevalence of condom use and the opportunity, ability and motivation to adopt healthier behaviors among Men at Risk in Central America, defined as: migrant workers, uniformed men (private forces), truckers, construction workers, bus drivers and fishermen, all of them potential clients of sex workers. 2. RESEARCH OBJECTIVES This study design is the first wave of TRaCs with Men At Risk. It pretends to respond to three fundamental questions. Monitoring: What are the levels in key behavioral indicators (condom use at last sex and consistent condom use) among Men at Risk? Segmentation: Which opportunity, ability and motivation constructs are significantly associated to safer behavior (condom use at last sex and consistent condom use)? Evaluation: what is the level of exposure to the Com-Prevention Program: % of Men at Risk going through at least 3 interpersonal communication activities (IPC), one biomedical component (HIV-STIs test and treatment if necessary), and one complimentary component (attendance to Family Planning Services and/or Alcohol/Drug Treatment Center) ? Is the exposure to such program associated to healthier behaviors?

1. TRaC研究的研究目标
本研究旨在收集中美洲高危男性（Men at Risk）的安全套使用流行率，以及其采纳更健康行为的机会、能力与动机构念的基线数据。本研究定义的高危男性包括：移徙工人、身着制服人员（私人武装力量）、卡车司机、建筑工人、公交司机及渔民，上述人群均为性工作者的潜在服务对象。
2. 研究目标
本研究为针对高危男性开展的TRaC研究第一波次调研，旨在回答三个核心问题：
监测问题：当前高危男性的关键行为指标（末次性行为安全套使用情况及持续安全套使用情况）处于何种水平？
群体细分问题：哪些机会、能力与动机构念与更安全行为（末次性行为安全套使用及持续安全套使用）存在显著关联？
项目评估问题：高危男性接触综合预防项目（Com-Prevention Program）的情况如何？具体而言，即完成至少3次人际沟通活动（Interpersonal Communication，下称IPC）、1项生物医学干预环节（必要时开展人类免疫缺陷病毒/性传播感染（HIV-STIs）检测与治疗）、以及1项补充环节（参与计划生育服务和/或酒精/药物成瘾治疗中心服务）的高危男性占比？该项目接触情况是否与更健康行为存在关联？
