This study determined the criterion validity and test–retest reliability of a brief park use questionnaire. From five U.S. locations, 232 adults completed a brief survey four times and wore a global positioning system (GPS) monitor for 3 weeks. We assessed validity for park visits during the past week and during a usual week by examining agreement between frequency and duration of park visits reported on the questionnaire to the GPS monitor results. Spearman correlation coefficients (SCC) were used to measure agreement. For past week park visit frequency and duration, the SCC were .62 to .65 and .62 to .67, respectively. For usual week park visit frequency and duration, the SCC were .40 to .50 and .50 to .53, respectively. Usual park visit frequency reliability was .78 to .88 (percentage agreement: 69%-82%) and usual park visit duration was .75 to .84 (percentage agreement: 64%-73%). These results suggest that the questionnaire to assess usual and past week park use had acceptable validity and reliability.

公园使用问卷的测量特性

本研究确定了一份简短的公园使用问卷的标准效度和重测信度。来自美国五个地点的 232 名成年人完成了四次简短的调查，并佩戴了全球定位系统 (GPS) 显示器 3 周。我们通过检查问卷中报告给 GPS 监测结果的公园访问频率和持续时间之间的一致性来评估过去一周和通常一周内公园访问的有效性。斯皮尔曼相关系数 (SCC) 用于测量一致性。对于过去一周的公园访问频率和持续时间，SCC 分别为 0.62 至 0.65 和 0.62 至 0.67。对于通常的一周公园访问频率和持续时间，SCC 分别为 0.40 至 0.50 和 0.50 至 0.53。通常公园访问频率的可靠性为 0.78 到 0.88（一致性百分比：69%-82%），通常公园访问持续时间为 . 75 到 0.84（百分比一致性：64%-73%）。这些结果表明，用于评估通常和过去一周公园使用情况的问卷具有可接受的有效性和可靠性。
