Xchange is an online registry of evidence-based prevention programmes. In its first phase, the registry will make available manualised interventions that European evaluation studies show have beneficial outcomes relating to substance use. For programmes of US origin, the registry also provides the evidence level of the evaluation studies conducted there (Blueprint ratings).
At present, Xchange contains 20+ manualised prevention programmes, all of which address substance use-related problems.
Xchange provides decisional support by continuously compiling information on implementation experiences with the programmes contained within it.
Users can access information on the effectiveness of a programme and on the extent to which it can be implemented. The real-life scenario in Europe’s multiple cultures is that a highly effective programme may not be easy to implement in a given country, while a less effective programme may be easier to implement.
