Who attends a free sexual health center in Paris for HIV/STI screening? an observational study.

Background: A key-population approach to sexually transmitted disease prevention does not fully take into account the multidimensional nature of sexual risk behavior. Visits to sexual health centers for HIV/STI screening provide an opportunity to spread prevention messages and tools, but few data are available on patients' sexual and prevention behaviors. This study aimed to identify the profile of patients consulting for HIV/STI testing in a Parisian sexual health center.

A validation of the Cannabis Abuse Screening Test (CAST) using a latent class analysis of the DSM-IV among adolescents.

This paper explored the latent class structure of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) (assessed with the Munich Composite International Diagnostic Interview). Secondly, the screening properties of the Cannabis Abuse Screening Test (CAST) in adolescents were assessed with classical test theory using the latent class structure as empirical gold standard. The sample comprised 3266 French cannabis users aged 17 to 19 from the general population.
