The challenge of measuring real world community-based interventions.
Exposure to a multi-level multi-component childhood obesity prevention community-randomized controlled trial: patterns, determinants, and implications. - PubMed - NCB
"Treatment effects may be attenuated in community-based trials, as
participants may be differentially exposed to intervention components
and the comparison group may also be exposed. Exposure should be
measured to provide context to impact evaluations in multi-level trials.
Future analyses linking exposure scores to the outcome should control
for potential confounders in the treatment-on-the-treated approach,
while recognizing that confounding and selection bias may exist
affecting causal inference."
"This manuscript adds to implementation science by proposing a detailed
protocol for the development of exposure scores (dose received)
evaluated through process evaluation and by informing further impact
analysis and intervention successes."
