title: The unique effects of environmental strategies in health promotion campaigns: a review.
abstract: Various strategies are used as tools in health promotion campaigns to increase health-related outcomes among target populations. Evaluations of these campaigns examine effects on changing people's knowledge, attitudes, and/or behaviors. Most evaluations examine the combined impact of multiple strategies. Less is known about the unique effects of particular strategies. To address this gap, we used highly systematic methods to identify and review scientifically rigorous evaluations of 18 campaigns that examined the unique effects of three sets of intervention strategies (entertainment education, law enforcement, and mass media) on changes in knowledge, attitudes, and practice with regard to various health behaviors. Results showed differences in evaluation processes based on the type of strategy used to promote campaign messages. For instance, evaluations of mass-media based campaigns were more likely to examine changes in knowledge, relative to evaluations of campaigns that used law enforcement strategies. In addition, campaign effects varied by particular strategies. Mass media-based campaigns were more likely to affect knowledge, relative to behaviors. Law enforcement and entertainment education-based campaigns showed positive effects on behaviors. The implications for planning and evaluating health promotion campaigns are described.
