|Looking Deeper into the HIV Epidemic: A questionnaire for Tracing Sexual Networks (Joint United Nations Programme on HIV/AIDS, 1998, 24 p.)|
This new sexual network module in the questionnaire is relevant for researchers and managers who want to have a better understanding of the dynamics of the HIV epidemic in a context where heterosexual transmission is predominant. For evaluation purposes, though, the standard questionnaire  is still recommended. Note that the general design of the population survey is still the same and that all the sections in the methods package on sampling, sample size and other issues remain quite useful.
Five teams of investigators have already applied this new module in Dakar, Senegal; Cotonou, Benin; Lusaka, Zambia; Kisumu, Kenya and Yaounde, Cameroon, with technical support from UNAIDS. Biological information on HIV infection and on STDs has also been collected at these sites.
It should be noted that although the makeup of the teams collecting behavioural data is essentially the same as for the earlier questionnaire, more training will be needed for the application of this new network module, and data analysis is also more complex. The average budget of US$ 30,000 for the survey should be increased by 15% to take into account increased efforts in training, a longer average time for interviews and more time spent on data analysis and report writing. UNAIDS and its partners stand ready to provide technical assistance in, for example, identifying consultants to help with training in both the administration of the survey and subsequent analysis of data.
