This paper reports on the systematization of an experience of evaluative and participative investigation relating to a DST/HIV/Aids prevention program that was implemented in the red-light zones of a remote municipality in the State of Amazonas. This perspective of qualitative evaluation emphasized issues that were not considered at the time of initially implementing this project among sex workers, relating to the dimensions of the constructions of collective meaning that were directly linked to the implementation of peer-based education. We have focused on this experience of community investigation with peer multipliers for the project and the reappropriation of the evaluation of their preventive and social actions. The results and discussion are presented as a double prism: 1 the sequence of "emerging" thematic questioning over the course of the participative action/investigation in the field; and 2 the pragmatic practices of the evaluative investigation within the sociocultural and sociopolitical context.
