Power Play! Campaign Research and Evaluation

The Power Play! Campaign model was developed through careful formative research  and proven effective through a large-scale evaluation study conducted in 1995. The Power Play! Campaign conducts regular formative, process, and impact evaluation on an ongoing basis and uses data from the California Children’s Health Eating and Exercise Practices Survey (CalCHEEPS), a biennial statewide survey of 9- to 11-year old children initiated in 1999. CalCHEEPS provided dietary and physical activity information which helped inform the Power Play! Campaign’s messages and interventions, assess its effectiveness, and guide future direction.

Impact Evaluation Study

In 2012, the Power Play! Campaign reached over 540,000 ethnically diverse, low-income 4th and 5th grade children across the state and partnered with approximately 680 of the qualifying schools statewide. A cluster randomized, controlled trial of approximately 4,000 4th and 5th grade children from low-resource schools in California demonstrated that the Power Play! Campaign had a beneficial impact on behaviors compared to control children by increasing: daily fruit and vegetable consumption (¼ cup/day more); daily physical activity time at school during recess and lunch (5 minutes more); and health-promoting knowledge, preferences, intentions, and social norms.
