The Game of Contacts
(Heavy drug users: Curitiba, Brazil)
The game of contacts data were collected as nested items in a behavioral surveillance study of heavy drug users in Curitiba, Brazil. This larger behavioral surveillance study was conducted by the Brazilian Ministry of Health and the Oswaldo Cruz Foundation as part of the 10-city Brazilian Behavioral Surveillance Study of heavy drug users (Bastos, 2009).
The game of contacts data enables researchers to estimate the network composition and social visibility of groups. These estimates may be of intrinsic interest or may be used to adjust estimates of the sizes of hard-to-count populations made using the network scale-up method. For additional information about the game of contacts see Salganik et al. (2011).
This public data release includes two data files on 294 respondents in comma separated values (CSV) format, 13 R programs, data documentation, and a copy of the interviewer form (in Portuguese) to record the game of contacts data. By running the R programs, one can reproduce all the graphical and tabular results as reported in Salganik et al. (2011).
