Environmental Sustainability and Behavioral Science: Meta-Analysis of Proenvironmental Behavior Experiments - Richard Osbaldiston, John Paul Schott, 2012
To provide practitioners with useful information about how to promote proenvironmental behavior (PEB), a meta-analysis was performed on 87 published reports containing 253 experimental treatments that measured an observed, not self-reported, behavioral outcome. Most studies combined multiple treatments, and this confounding precluded definitive conclusions about which individual treatments are most effective. Treatments that included cognitive dissonance, goal setting, social modeling, and prompts provided the overall largest effect sizes (Hedge’s g > 0.60).
