We are a group of teachers and researchers coming from different Universities (Bordeaux2, Bologna, Gent, Extremadura, Stirling), that are aiming to connect the academic world with practice, by building out research and training projects in the field of treatment and prevention for people with substance misuse problems . One of these projects covers the assessment of substance misuse. The main aim of this survey is to investigate about the availability of data collected with ASI/EuropASI or “ASI like” instruments (add some examples: if someone doesn’t know the ASI, how will he / she know what an ASI-like instrument is) in your community. By answering these few questions, you will help us to understand how to design further research projects on assessment and treatment, and to have a better knowledge of the state of art of data collection in Europe. We are very grateful of the time you dedicate to us and we will update you about possible development.
