National Survey of Adolescents, 2004: Malawi

The National Survey Adolescents was launched in 2004 in four Sub-Saharan African countries--Burkina Faso, Ghana, Malawi, and Uganda--to provide detailed information on adolescent risk-taking and health-seeking behavior as related to HIV, STDs and unintended pregnancy. The study examined a range of factors (e.g., behavioral, sociocultural, economic) that could lead to increased vulnerability to risk. The study also encompassed knowledge of means of prevention, sources of trusted information and health care, and impediments to adolescents' abilities to apply their knowledge and take preventive action. The survey in Malawi was administered between March and June 2004 and again in August 2004. Using a two-stage stratified sample design that selected households from rural and urban clusters, 7,750 households were listed for initial screening. After an initial interview in each household, individual surveys were administered in person to adolescents between the ages of 12 and 19 who were de facto or de jure members of the household. However, during the initial data collection period this process collected only 3,448 individual interviews with adolescents. Consequently, in August 2004, researchers extended the surveys to additional clusters excluded during the first round of surveys bringing the total number of individuals to 4,879. Because of the sensitive nature of questions administered in the survey, informed consent forms were obtained from both parents/guardians and the respondents, and in all possible instances interviewers and respondents were paired up by gender.

《国家青少年调查》项目于2004年启动，旨在四个撒哈拉以南非洲国家——布基纳法索、加纳、马拉维和乌干达——提供有关青少年风险行为及与艾滋病、性传播疾病及意外怀孕相关的健康寻求行为的详细信息。研究考察了一系列可能导致风险易感度增加的因素（例如，行为、社会文化、经济因素）。研究还涵盖了预防手段的知识、可信信息来源以及医疗保健，以及青少年应用其知识并采取预防措施的能力的障碍。马拉维的调查于2004年3月至6月进行，并于同年8月再次进行。该调查采用两阶段分层抽样设计，从农村和城市群体中选取家庭，共计7,750户家庭被列入初步筛选名单。在每户家庭进行初步访谈后，对12至19岁的实际或法定家庭成员进行了面对面个体调查。然而，在最初的数据收集期间，此过程仅收集了3,448份青少年的个体访谈。因此，在2004年8月，研究人员将调查扩展到第一轮调查中未被纳入的额外群体，使得总人数达到4,879人。鉴于调查中提出的问题具有敏感性，从父母/监护人及受访者处获得了知情同意书，并在所有可能的场合，访谈者和受访者均按照性别配对。
