This paper presents both the procedure and the results of an evaluation of Tête à Queue, a condom promotion magazine for youth outside the school system. Three studies were conducted: a survey among practitioners, an experimental study to test the effects of the magazine on youths' attitudes and intentions regarding condom use, and a critical analysis of the controversy that surrounded the diffusion of the magazine. Results show that aspects related to the definition of the need to the definition of the target population, diffusion strategy, and some specific contents account for some of the difficulties encountered during the course of the project.
