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:
“Man always made, and still makes, grotesque blunders in selecting and measuring forces, taken at random from the heap, but he never made a mistake in the value he set on the whole, which he symbolized as unity and worshipped as God. To this day, his attitude towards it has never changed, though science can no longer give to force a name.”
—Henry Brooks Adams (1838–1918)
