Abstract
To compare changes in AIDS knowledge and risk behaviors among Brazilian cocaine users in an intervention trial. 119 participants were randomly assigned to either a standard or a standard plus "thought mapping" intervention, and re-interviewed 2 and 8 weeks after intake using standardized data collection instruments. Intervention effects were examined using generalized estimated equation model. Significant increases in AIDS knowledge and condom use were observed in the experimental group, as well as significant changes in the subscores for sexual and drug risks. The experimental intervention was less successful in decreasing mean days of cocaine use when compared to the standard. Although not robust, the findings nevertheless suggest that components of the experimental thought-mapping model might be useful in combination with other approaches.
