We determined the criterion validity and test-retest reliability of a brief park use questionnaire. From five US locations, 232 adults completed a brief survey four times and wore a global positioning system (GPS) monitor for three 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 in 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 0.62-0.65 and 0.62-0.67, respectively. For usual week park visit frequency and duration, the SCC were 0.40-0.50 and 0.50-0.53, respectively. Usual park visit frequency reliability was 0.78-0.88 (percent agreement 69%-82%) and usual park visit duration was 0.75-0.84 (percent agreement 64%-73%). These results suggest that the questionnaire to assess usual and past week park use had acceptable validity and reliability.
我们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调查，并佩戴全球定位系统（GPS）监测器三周。我们通过检查问卷中报告的公园访问频率和持续时间与GPS监测结果之间的一致性，评估了过去一周和平时一周公园访问的效度。使用斯皮尔曼相关系数（SCC）来衡量一致性。对于过去一周的公园访问频率和持续时间，SCC分别为0.62 - 0.65和0.62 - 0.67。对于平时一周的公园访问频率和持续时间，SCC分别为0.40 - 0.50和0.50 - 0.53。平时公园访问频率的信度为0.78 - 0.88（一致率69% - 82%），平时公园访问持续时间的信度为0.75 - 0.84（一致率64% - 73%）。这些结果表明，用于评估平时和过去一周公园使用情况的问卷具有可接受的效度和信度。
