The BSS is a monitoring and evaluation tool that uses HIV and sexually transmitted
diseases (STD) serologic surveillance methods to track trends in HIV/AIDS-related
knowledge, attitudes and behaviour in at-risk populations such as sex workers,
injecting drug users, migrant men, and truck drivers, among other groups. 4 The BSS
sets a standard methodology for sampling, survey development, implementation and
analysis. BSS findings “yield evidence of project impact, provide indicators of
project success and highlight persistent problem areas, identify appropriate
intervention target populations, identify specific behaviors in need of change, function
as a policy and advocacy tool, and supply comparative data concerning behavioural
risk.” 5
This study used the modules for commercial sex workers and for men. In addition, a
qualitative module was added for gatekeepers and a quantitative module was added
for condom sales outlets. Extra questions on condoms were added to the
questionnaires for commercial sex workers and men.
Detailed information on the methodology and fieldwork for this study is contained in
the main report of the sex workers. In all, 811 interviews were completed (out of
1,252 sex workers contacted) in five types of sex work facilities (bars/karaoke clubs,
beauty saloons, sauna/houses, night clubs/hotels, and on the street). The study was
conduced in 12 locations, six each in Yunnan and Sichuan provinces (the capital city,
the prefectural city and four towns in each province).
