Objective: To evaluate the utility of the Werry-Weiss-Peters Activity Rating Scale (WWPARS) for children with a Chinese background. Methods:In the city of Changsha, 465 normal children aged 8～12 in two primary schools and 27 ADHD children in an outpatient department were tested with WWPARS. Psychometric properties of the scale were analyzed for reliability and validity. Results: While levels of activity increased with age for all children, there was no significant difference between the two groups assessed. The scale attained good reliability and validity. Conclusion: This scale can be applied for evaluation of activity levels for Chinese children.
