Reliable and comprehensive measurement of physical activity settings is needed to examine environment-behavior relations.
Surveyed park professionals (n = 34) and users (n = 29) identified park and playground elements (e.g., trail) and qualities (e.g., condition). Responses guided observational instrument development for environmental assessment of public recreation spaces (EAPRS). Item inter-rater reliability was evaluated following observations in 92 parks and playgrounds. Instrument revision and further reliability testing were conducted with observations in 21 parks and 20 playgrounds.
EAPRS evaluates trail/path, specific use (e.g., picnic), water-related, amenity (e.g., benches), and play elements, and their qualities. Most EAPRS items had good-excellent reliability, particularly presence/number items. Reliability improved from the original (n = 1088 items) to revised (n = 646 items) instrument for condition, coverage/shade, and openness/visibility items. Reliability was especially good for play features, but cleanliness items were generally unreliable.
The EAPRS instrument provides comprehensive assessment of parks' and playgrounds' physical environment, with generally high reliability.
为研究环境与行为的关系，需要对身体活动环境进行可靠且全面的测量。
对公园专业人员（n = 34）和使用者（n = 29）进行调查，以确定公园和游乐场的元素（如步道）和特征（如状况）。这些回答为公共休闲空间环境评估（EAPRS）的观察工具开发提供了指导。在92个公园和游乐场进行观察后，评估了项目的评分者间信度。在21个公园和20个游乐场进行观察后，对工具进行了修订并进一步进行了信度测试。
EAPRS评估步道/路径、特定用途（如野餐）、与水相关的、便利设施（如长椅）和游乐元素及其特征。大多数EAPRS项目具有良好至优秀的信度，尤其是存在/数量项目。对于状况、覆盖/遮荫和开放度/能见度项目，信度从原始工具（n = 1088个项目）到修订工具（n = 646个项目）有所提高。游乐设施的信度特别好，但清洁项目通常不可靠。
EAPRS工具对公园和游乐场的物理环境提供了全面评估，信度普遍较高。
