摘要
目的采用两种资料收集方法测量全球体力活动量表(GPAQ)的信度与效度,评价两种测量方法结果的等同性。方法使用GPAQ分别对两组高血压患者采用自填法、访谈法进行2次体力活动测量,计算重测信度系数、一致性系数;采用计步器与国际体力活动问卷评价GPAQ的效标效度。结果两种方法测得的组内相关系数在重度体力活动(工作)、总中等强度体力活动、总中-重度体力活动方面比较差异有统计学意义(P<0.05)。在不同级别体力活动水平测量方面,两种方法测量一致性系数分别为0.37、0.31;在是否达到高血压患者推荐的体力活动水平方面,两种方法测量一致性系数分别为0.33、0.34。计步器、国际体力活动问卷与GPAQ测得的相关系数为0.19~0.46。结论 GPAQ具有较好的信度与效度,适于在高血压这一慢性病群体中推广应用。使用自填法测量的GPAQ信度和效度与访谈法测量的结果基本一致,提示可以采用自填法使用GPAQ测量人群的体力活动状况。
Objective To test the validity and reliability of global physical activity questionnaire （GPAQ） by using two methods for collecting data,and to evaluate the equality of two measure methods. Methods The physical activity （PA） in two hypertension groups was examined twice with GPAQ by using self-administered and interview methods respectively. The test-retest reliability coefficient and consistency coefficient were calculated based on the results of two groups. The criterion validity of GPAQ was assessed by adopting pedometer and international physical activity questionnaire （IPAQ）. Results The intra-group relative co- efficient detected by two methods had statistical difference in the aspects of,the vigorous PA （work）, total moderate PA and total moderate-vigorous PA（P〈0.05）. In the aspect of different grades of PA level measurement, the consistency coefficients detected by two methods were 0.37 and 0.31 respectively;in the aspect of whether reaching recommended PA level in hypertensive patients, the consistency coefficients detected by two methods were 0.33 and 0.34 respectively. The relative coefficient detected by pedometer, IPAQ and GPAQ was 0.19-0. 46. Conclusion GPAQ has good reliability and validity,is suitable to be popularized and applied in the group of chronic disease hypertension. The validity and reliability of GPAQ measured by the self-administered method are consistent to those measured by using the interview method,prompting that the self-administered method may be used to measure PA status in population by GPAQ.
