RUSSIA (2009): SUBSTANCE USE AND HIV/AIDS TRAC STUDY ASSESSING RISK BEHAVIOR AND SEEKING OF MEDICAL SERVICES AMONG STUDENTS OF VOCATIONAL TRAINING COLLEGES IN EKATERINBURG ROUND ONE

This is the first stage of a study conducted among students of vocational training colleges (referred to as PTUs) in Ekaterinburg. The goals of the study were: to assess key behavioral patterns related to health, HIV prevention, and drug use; and to outline determinants of high-risk behavior (with regard to HIV). The study's design is experimental: two groups are compared to one that is subject to measures implemented by PSI/Russia, and one that is not. This stage describes baseline data before PSI/Russia measures are implemented in the intervention group. For the purposes of the analysis the sample from PTUs where the intervention is to be implemented are referred to as the \"intervention group\". The sample from PTUs where there are currently no plans for the PSI intervention to be implemented are called the \"reference group.\" The study is based on a random sample of students of vocational training colleges with dormitories. Each student's chances of becoming part of the study group was proportional to the size of the PTU, i.e. students from larger PTUs had a greater chance of becoming part of the study, but the chances of any student from a given PTU were equal to those of every other student at the same PTU. Sample sizes for both groups are enough to conduct monitoring analysis and total sample (both groups together) is enough to perform segmentation analysis. With regard to the fact that some of the students were under 18, their participation in t he study was only possible with written consent of their parents or guardians. Participation was voluntary; students had to personally give oral consent for interviews. Interviews were conducted in rooms that ensured confidentiality.

本研究为在叶卡捷琳堡市职业技术学院（Vocational Training Colleges，简称PTUs）学生中开展的第一阶段研究。本研究的核心目标为：评估与健康、人类免疫缺陷病毒（Human Immunodeficiency Virus，HIV）预防及药物滥用相关的核心行为模式，并梳理与HIV感染相关的高危行为决定因素。本研究采用实验性设计：将研究对象分为两组，一组接受PSI/Russia推行的干预措施，另一组不接受相关干预，对两组进行对照分析。本阶段呈现的是干预组实施PSI/Russia干预措施前的基线数据。为便于后续分析，将计划开展PSI干预的职业技术学院的学生样本定义为"干预组"，将当前暂无PSI干预计划的职业技术学院的学生样本定义为"参照组"。本研究基于开设宿舍的职业技术学院学生的随机抽样样本。每名学生入选研究样本的概率与其所在PTU的规模成正比，即规模更大的PTU的学生入选概率更高，但同一PTU内的所有学生的入选概率完全均等。两组样本量均足以开展监测分析，总样本（两组合计）则足以开展细分群体分析。鉴于部分学生未满18周岁，其参与本研究需获得父母或法定监护人的书面同意。本次研究参与完全自愿，学生需亲自口头确认同意接受访谈。访谈均在保障隐私与保密性的房间内进行。
