Behavioral assessment of physical activity in obese preschool children
Journal of Applied Behavior Analysis
We measured changes in physical activity in 2 obese preschool children when a package intervention was evaluated in a reversal design. Physical activity was measured via direct observation and pedometers. Although the intervention produced only modest increases in activity, the results provide preliminary concurrent validation for the dependent measures used, in that the two measures covaried and a similar degree of change was observed with each across baseline and intervention phases.
