Design And Validation Of College Students Physical Activity Questionnaire

Research purposes:With the development of contemporary society and ever-increasing economic level,people's lifestyles have undergone great changes.While the emergence of high-tech has brought convenience to people,many adverse effects have been produced in succession,causing serious harm People's physical and mental health,lack of physical activity and prolonged sit-in are the main causes of various diseases and deaths.As the future builders of social undertakings,the good health of college students will work well for all aspects of work A good role in promoting.According to the existing problems of physical activity of college students,the designed physical activity questionnaire of college students can well calculate the level of physical activity such as work-study,traffic trip,dormitory life,exercise and leisure,sleeping and three levels of low,middle and high intensity the amount.It is great practical significance to guide college students' study and life by effectively monitoring energy consumption of physical activity of college students and timely and effective intervention in all aspects of physical health so that they can not be pre-cured.Research methods:Through the careful study of the IPAQ questionnaire,I learned about the structure of the IPAQ questionnaire,data cleaning,calculation methods of physical activity levels,and grouping standards.From the international distribution of 2011 third edition of the outline of the physical activity attached to the MET values extracted from college students physical activity related entries,and the relevant experts to discuss and decide the content of the questionnaire.Based on the content structure of IPAQ,a preliminary attempt is made to design a draft,and the related reliability and validity verification is carried out.Through the statistical analysis of the relevant data of a manuscript,the content and the structure of the manuscript are revised again to obtain two manuscripts,and the validity and reliability of the manuscripts are verified.On the test of good questionnaires for physical activity level grouping,and ultimately determine the final version of college students physical activity questionnaire.Research result:After two rounds of design,revision and verification,the questionnaire of college students' physical activity got a good test in terms of reliability and validity.After correlation analysis,the correlation coefficient of pearson between the two questionnaires was 0.85(P <0.01),and the validity was good.And through the regression analysis of the questionnaire of IPAQ long scroll and college students physical activity,the regression equation of the two is established as follows: Total energy consumption of college students = 3214.67 + 0.86 * The total energy consumption of IPAQ long scroll.In terms of reliability verification,pearson correlation coefficient of physical activity questionnaire of college students reached 0.97(P <0.01),pearson correlation coefficient of IPAQ long questionnaire reached 0.96,and reliability of the two questionnaires showed good,with no statistical difference.In the questionnaire of physical activity of college students,the correlation coefficients of dormitory living,exercise and leisure were 0.90 and 0.92(P <0.01),all of which reached above 0.9.The correlation coefficients of work study and social interaction were 0.88,0.87(P <0.01),which is above 0.8;while the correlation coefficients in traffic travel and sleep rest were 0.78 and 0.79 respectively(P <0.05),with statistical significance.In the reliability test of IPAQ long roll,the correlation coefficients of housework,exercise and leisure,non-workday and workday rest were 0.92,0.93,0.95,0.95 respectively(P <0.01),all of which were above 0.9 However,the correlation coefficient was only 0.83(P <0.05)in terms of traffic trips,but overall the reliability between the two measurements was still good.Research conclusion: 1.The completed questionnaire of physical activity of college students can be well applied to the investigation of the level of physical activity of college students and plays an important role in evaluating the life style of college students.2.After two rounds of design modification,the physical activity questionnaire of college students adapts well to the cognitive level of college students in content and structure.3.After two rounds of test of reliability and validity,the questionnaire of physical activity of college students has been verified by the reliability and validity of the college students.4.The completed questionnaire of college students' physical activity has not been well divided on the level of physical activity,and the grouping needs to be further explored.
