South Africa (2007): MAP Study Evaluating Coverage and Quality of Coverage of Lovers Plus and Trust Condoms in Cape Town, Durban, and Johannesburg Second Round

The three cities (Johannesburg, Cape Town and Durban) where the Dutch government is funding were a focal for the MAP study. The primary sampling unit was Sub Places (SPs). Only SPs that are classified as urban or suburban were included. The Lot Quality Assurance sampling was employed, which allows for sensibly accurate estimates of coverage and quality of coverage for an entire supervision area. In each city a representative sample of HTAs and non-HTAs was randomly selected. The same sampling frame - which was obtained from Statistics South Africa - as that used for MAP phase I sampling was used to select the sample for MAP phase II. An audit sheet built onto PDAs was used to collect the data. Each PDA was synchronized into ACCESS. The data was subsequently exported and processed in SPSS.

荷兰政府资助的三座城市（约翰内斯堡、开普敦及德班）为本MAP研究的核心调研区域。本研究的基本抽样单元为次级街区（Sub Places, SPs），仅纳入被归类为城市或城郊的次级街区。研究采用批量质量保证（Lot Quality Assurance, LQA）抽样法，该方法可对整个监管区域的覆盖情况及覆盖质量实现较为精准的估算。各城市均随机抽取HTAs与非HTAs的代表性样本。本次MAP第二阶段抽样所使用的抽样框，与MAP第一阶段抽样采用的抽样框一致，该抽样框源自南非统计局（Statistics South Africa）。研究采用搭载于PDA（Personal Digital Assistant, PDA）的审计表单开展数据采集，每台PDA均与ACCESS数据库完成同步。后续将采集数据导出，并在SPSS（Statistical Product and Service Solutions, SPSS）中完成处理。
