To assess the test-retest reliability and criterion validity of the Simplified Chinese-character version of the International Physical Activity Questionnaire Long form (IPAQ-L) in urban community-dwelling adults in Hanghzou, China.
A total of 158 eligible participants aged 25-59 years from 6 neighbourhoods in two central districts of Hangzhou completed the IPAQ-L questionnaire twice within a 7-day interval. Half of the subjects wore pedometers during the first 7 days. Test-retest reliability was examined by comparing the first (Day 1) and the second (Day 9) survey of IPAQ-L. Criterion validity was assessed by comparing IPAQ-L with pedometer data.
Modest to good test-retest reliability was found with intraclass correlation coefficients of 0.67 for total PA, 0.37 to 0.73 for specific dimensions, and 0.56 to 0.71 for different intensities of PA. Total PA measured by IPAQ-L was moderately correlated with exercise levels (partial r = 0.27, P = 0.020) and walking distance (partial r = 0.31, P = 0.007), which were measured by a pedometer, after adjusting for gender, age, educational attainment and employment status.
Our results indicate that the IPAQ-L is a reliable and validated measure for assessing physical activity levels in this population and possibly the adult population in other mainland Chinese cities.
评估国际体力活动问卷长表（IPAQ-L）简体中文版在中国杭州城市社区成年人中的重测信度和效标效度。
来自杭州市两个中心区6个社区的158名年龄在25 - 59岁的合格参与者在7天内两次完成IPAQ-L问卷。一半受试者在前7天佩戴计步器。通过比较IPAQ-L的第一次（第1天）和第二次（第9天）调查来检验重测信度。通过将IPAQ-L与计步器数据进行比较来评估效标效度。
发现重测信度从中等至良好，总体力活动的组内相关系数为0.67，特定维度的组内相关系数为0.37至0.73，不同强度体力活动的组内相关系数为0.56至0.71。在调整性别、年龄、教育程度和就业状况后，IPAQ-L测量的总体力活动与计步器测量的运动水平（偏相关系数r = 0.27，P = 0.020）和步行距离（偏相关系数r = 约0.31，P = 0.007）中度相关。
我们的结果表明，IPAQ-L是评估该人群以及可能中国其他内地城市成年人群体力活动水平的可靠且有效的测量工具。
