Using interactive behavior change technology to intervene on physical activity and nutrition with adolescents.

The use of interactive technologies to promote health behaviors is a rapidly expanding field. Yet, the integration of these technologies in the development of physical activity and nutrition interventions for adolescents is in its infancy. Health in Motion, a multimedia obesity-prevention program for adolescents, is described as a case example of a Web-based interactive program for promoting physical activity and fruit and vegetable consumption among high school students.

Acceptability of a school-based intervention for the prevention of adolescent obesity.

This article describes the development and pilot testing of a computer-based, multiple-behavior obesity prevention program for adolescents. Using the Transtheoretical Model as a framework, this intervention offers individualized feedback based on readiness to engage in physical activity, to consume fruits and vegetables, and to limit television viewing. Focus groups and interviews with students, teachers, school administrators, and experts guided the development.
