Pilot Program Fails to Boost Physical Activity Among Teen Girls, Spring Weather Works Better

Development and evaluation of an interactive physical activity program for girls

Researchers at the University of Michigan School of Nursing developed a 12-week computer-based interactive intervention to encourage adolescent girls to be more physically active, and tested it among girls in two low-income areas.

Key Findings

  • There was no significant difference between the control and intervention groups in the amount of physical activity they engaged in during the project.
  • Both groups reported a significant increase in days per week of physical activity.
  • The project director attributed this increase in part to a seasonal variation in activity: the pretest took place in the winter and the post-test in the spring.
