Surveys and questions within surveys that work well in one setting may not be relevant or clear in another setting. Therefore, we strongly suggest that all users follow the usual procedures of survey research and pretest questionnaires carefully. An example of triangulation would be to combine clinic service statistics and the observation of patient-provider interactions with the results from a standardized survey. Horizons has collected instruments from a number of international and local organizations, as well as from the published literature. Some surveys were designed for global use, some for use in the United States, and others for use in Africa, Asia, or Latin America.
Most surveys are available in English, but some are also available in other languages.
For ease of survey development, surveys have been presented in two forms. Complete instruments can be found in the Full Instrument section. Selected questions have also been separated into AIDS-related topic areas. An introduction accompanies each of the topic areas, to discuss methodological issues related to survey development. Summaries of the development and prior use of questionnaires are included in the Survey Development and Validation Summaries section.
