Test-retest reliability of a preadolescent environmental access to physical activity questionnaire

Background: Physical activity behavior is an important aspect of overall health, and it is important to understand determinants of physical activity in order for children to accumulate the recommended levels. The ecological-systems theory describes the relationship between individuals and their contexts, suggesting that environment affects physical activity behaviors. Researchers should measure children's access to physical activity to determine environmental influences. At the time of data collection, however, no reliable questionnaires had been created for measuring children's access to physical activity. Methods: Students from grades 4 and 5 completed a physical activity environmental-access questionnaire on 2 occasions, approximately 7 to 10 days apart. Results: The questionnaire appeared appropriate for children age 9 to 12. The lowest reliability was found with items located in the school environment. Conclusions: This questionnaire is a suitable tool for examining children's physical activity supports and inhibitors.
