Describes methods to evaluate community-wide interventions, when random assignment studies are inappropriate.
"Most community-wide initiatives are fundamentally incompatible with commonly used evaluation methods, and random assignment frequently represents a very poor evaluation design in this setting... [For example, these initiatives] are 1) designed to capitalize on spillover effects from participants in programs on those who never participate; 2) offer linked sets of services and case management rather than a single, specific treatment or intervention..; and 3) are tailored to specific local conditions and capacity in a way that makes each initiative unique in its particular mix of program components.... However, there are evaluation methods that can address these challenges.... Innovative methods, many of which use propensity score reweighting methods in novel ways, can address the fundamental challenges" of evaluating community-wide initiatives (p.1).
