title: Using thought mapping and structured stories to decrease HIV risk behaviors among cocaine injectors and crack smokers in the South of Brazil.
abstract: OBJECTIVE
  To compare changes in AIDS knowledge and risk behaviors among Brazilian cocaine users in an intervention trial.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Although not robust, the findings nevertheless suggest that components of the experimental thought-mapping model might be useful in combination with other approaches.
