Assessment of a pilot video's effect on physical activity and heart health for young children.

This article assessed the effects of a video, "Dynamotion," on children's knowledge, self-efficacy, and attitude about physical activity and heart health. A quasi-experimental design was used; 12 classrooms (grades K-2) were assigned to intervention (N = 116) or comparison (N = 92) groups. Students completed a 9-item pre- and posttest; only the intervention group was exposed to the video, during which qualitative assessments were made. Repeated measures analyses were used to detect changes. Overall, the intervention group had greater gains in knowledge and self-efficacy than did the comparison group (p < 0.001), and they seemed to enjoy the video. The results suggest that exposure to a short, interactive, educational video may promote health among young children.
