Evaluation of a dependent group contingency to increase physical activity during recess
Due to the increasing rates of type II diabetics, cardiovascular disease, and childhood obesity, ways to increase physical activity are needed. The researchers examined the use of a dependent group contingency to increase physical activity of a 4th grade class during recess as measured by a pedometer. Results showed that step counts declined after the initial baseline; therefore, we evaluated procedural modifications (i.e., new prizes and criterion) in a multielelment design. After the procedural modifications, step counts increased toward the initial baseline during the last sessions of the multielement design. We discuss variables that may have influenced the results and indicate areas for future research.
