Abstract

OBJECTIVE

To test the reliability and validity of International Physical Activity Questionnaires (long self-administrated format) (IPAQ), Chinese version on women of 12 - 44 years old, in Chengdu city.

METHODS

Clustered sampling was used, according to the age distribution of investigated population. One community, one university and two middle schools (including one high school and one junior high school) in Chengdu were selected. The reliability study was conducted in a 28-day period. Participants were contacted three times within 28 days (on the 1(st), the 8(th) and the 28(th) day respectively). In the validity study, participants completed the same questionnaire and Bouchard physical activity diary (PA diary) each day for seven days between visit 1 and visit 2 before comparing the IPAQ's result with Bouchard physical activity diary's for validity study. Pearson or Spearman' correlation coefficients were calculated for validity and interclass correlation coefficients for reliability according to date distribution.

RESULTS

(1) One hundred and eighty six participants were recruited for the reliability study. All of them completed the first questionnaire with 143 (76.88%) and 172 (92.50%) finished the second and third questionnaires. One hundred and fifty eight participants were recruited in the validity study. Qualified questionnaire accounted for 90.59% (143). (2) Results from the test-retest reliability of the Chinese version of long self-administrated format (IPAQ) showed: the ICC after one week ranged from 0.7373 to 0.972 (mean: 0.870) which were higher than those interval's reliability [ICC = 0.472 - 0.948 for three weeks interval (mean: 0.721), and 0.473 - 0.925 for four weeks interval (mean: 0.696)]. The ICCs of three weeks interval and four weeks interval were not significantly different. ICCs for vigorous physical activity and leisure time physical activity were the best. (3) The validity for different intensity, total physical activity and sitting time showed the correlation coefficients between IPAQ and PA diary ranged from 0.445 to 0.696, with correlation for vigorous physical activity the best (r = 0.696).

CONCLUSION

IPAQ-C seemed a reliable and validated measure of physical activity for 12 - 44 year-old women in Chengdu city.

摘要

目的

测试国际体力活动问卷（长自填式格式）（IPAQ）中文版在成都市12 - 44岁女性中的信度和效度。

方法

根据被调查人群的年龄分布采用整群抽样。选取成都市的1个社区、1所大学和2所中学（包括1所高中和1所初中）。信度研究为期28天。在28天内对参与者进行3次随访（分别在第1天、第8天和第28天）。在效度研究中，参与者在第1次和第2次访视之间的7天内每天完成相同的问卷和布沙尔体力活动日记（PA日记），然后将IPAQ的结果与布沙尔体力活动日记的结果进行比较以进行效度研究。根据数据分布计算Pearson或Spearman相关系数用于效度分析，组内相关系数用于信度分析。

结果

（1）招募了186名参与者进行信度研究。他们全部完成了第一份问卷，143名（76.88%）完成了第二份问卷，172名（92.50%）完成了第三份问卷。招募了158名参与者进行效度研究。合格问卷占90.59%（143份）。（2）长自填式格式（IPAQ）中文版的重测信度结果显示：一周后的组内相关系数（ICC）范围为0.7373至0.972（均值：0.870），高于那些间隔时间的信度[三周间隔的ICC = 0.472 - 0.948（均值：0.721），四周间隔的ICC = 0.473 - 0.925（均值：0.696）]。三周间隔和四周间隔的ICC无显著差异。剧烈体力活动和休闲时间体力活动的ICC最佳。（3）不同强度、总体力活动和久坐时间的效度显示，IPAQ与PA日记之间的相关系数范围为0.445至0.696，其中剧烈体力活动的相关性最佳（r = 0.696）。
