Few studies have explored barriers to physical activity in parks and streets among children, adolescents, and their parents. The purpose of this article is to evaluate the psychometric properties of a new survey of barriers to physical activity in neighborhood parks and streets. Adolescents and parents of children and adolescents completed surveys twice. Two barrier subscales (environment and safety) emerged that applied to both locations and all participant groups. Results generally supported acceptable, internal consistency as well as construct validity, but test-retest reliabilities were lower than desired. These scales may be used to improve understanding of perceptions of barriers to physical activity in neighborhood parks and streets, but further development is needed.
