Abstract:
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 coefficient 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,theconsistency 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,promptingthat the self-administered method may be used to measure PA status in population by GPAQ.
