“Which prevention programs and policies are truly worthy of being considered “evidence-based”? I’ve been thinking about the answer to this challenging question for decades.  The difference between what can – and what should not – be called “evidence-based” is often critical, if we are  to avoid wasting the limited available resources we can expend on prevention.  But that difference is often difficult to discern, and as evidence accumulates  over time the status of a given program and policy may well change.  Sifting through the evidence on a continuing basis, and making recommendations as to what should and should not be implemented, is the job of the entire community involved in the application of prevention science.”
