目的：修订中文版的青少年体力活动问卷（PAQ-A）,评估其信效度,为大样本的青少年体力活动提供测量工具。方法：选取125名13～14岁（男56人,女69人）健康青少年,间隔1周前后2次填写问卷,检验重测信度;招募47名（男17人,女30人）自愿佩戴加速度计者,佩戴7 d后填写问卷,以Actigraph GT3X＋加速度计为效标,进行效度检验。采用Cronbach＇sα系数检验问卷的内部一致性信度,Spearman等级相关检验重测信度和效标效度。结果：第1次、第2次发放问卷的内部一致性信度分别为0.82、0.85;删掉午休期间活动Q3前后,问卷重测信度从0.79增加到0.81,问卷稳定性良好。效度检验,问卷整体得分与加速度计计数值、中等到较大强度体力活动（MVPA）百分比均呈中度相关,相关系数r分别为0.48、0.39（P〈0.05）;删去Q3后,相关系数分别为0.51、0.40（P〈0.05）,且修订后问卷与加速度计的相关系数高于原文使用时的效度系数0.33。结论：修订后的PAQ-A中文版具有可接受的信度和效度,可以用于大样本的中国青少年体力活动评估研究。

Objective ： This study aimed at providing a reliable tool for the assessment of physical activity of children and adolescents in large sample, the reliability and validity of Physical Activity Questionnaire for Adolescents （PAQ-A） in Chinese version were evaluated. Methods：One hundred and twenty-five 13 ～14 years old healthy ado- lescents （56 boys ,69 girls）were recruited from a junior school, and they did the PAQ-A twice to evaluate test-re- test reliability. And validity of PAQ-A was tested by comparing its results with those from an activity monitor （ Ac- tiGraph GT3X ＋ accelerometer） in 47 adolescents. Internal consistency reliability of PAQ-A was measured by Cronbach＇s α,test-retest reliability and validity were tested by Spearman correlation. Results：Cronbach＇s α ranged from 0. 82 to 0. 85. Test-retest reliability was improved from 0. 79 to 0. 81 after that the Q3 （lunch time activity） was omitted. Associations between the PAQ-A summary score and activity monitor variables were r = 0. 48 for total PA and r =0. 39 for moderate and vigorous activity （P 〈0. 05） ,and r =0. 51,0.40 respectively after deleting the Q3. The validity of rectified PAQ-A （ Chinese version） was higher than original one （ r = 0. 33 ）. Conclusion ： The PAQ-A of Chinese version shows good internal consistency and acceptable validity,which is available for physical activity assessment of Chinese adolescents.
