Measuring Effectiveness
Research in injury prevention is challenging, because the usual outcome of interest is deaths or injuries prevented, and it is nearly impossible to measure how many people did not get hurt who otherwise would have. Education efforts can be measured by changes in knowledge, attitudes, beliefs and behaviors, before and after the intervention, however tying these changes back into reductions in morbidity and mortality is often problematic.
Examining trends in morbidity and mortality in the population is usually not difficult and may provide some indication of the effectiveness of injury prevention interventions. However, this approach suffers from the potential of ecological fallacy, where the data shows an association between an intervention and a change in the outcome, but there is actually no causal relationship.

Famous quotes containing the word measuring:
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. Strong and Sensitive Cats, Atlantic Monthly (July 1994)
