A Study On The Evaluation Index System Of Physical Activity Environment Of Middle School Students

Objective:(1)The system analysis of the effect in physical activity environment factors in youth;(2)The index system construction of youth physical activity environment evaluation;(3)Application of the index system of youth physical activity environment evaluation.Methods:(1) The literature analysis method:retrieving physical activity promotion related policy documents,searching the Chinese and foreign literature relevant to the physical activity environment of the youth,reading the Environmental Behavior, Environmental Psychology, Social Psychology and other related books.(2) Delphy:two rounds of expert consultation to survey involved in the investigation of the experts based on. In this study, the full collection of index system of youth physical activity environment evaluation opinions and suggestions.(3) The analytic hierarchy process:according to the logical relationship between the indicators of adolescent physical activity and environmental evaluation of each other, the use of Yaahp software to construct structured hierarchical model. The hierarchical model of internal structure of the comparison matrix based on the two two index. The experts issued to AHP questionnaire, comparison of various levels of internal index based on the relative importance of each other.(4)questionnaires:according to the environmental index system construction of the adolescent physical activity, adolescent self perceived physical activity environment questionnaire. And the Xuzhou city two middle school students were issued.Results:(1) to construct the index system of youth physical activity environment evaluation, and determines the weight of each index. Includes 4 first level indexes and 17 two level indexes.4 first class indexes are "school environment" and "family environment", "community environment","individual environmental".The weight were 42.14%,16.67%,5.17%,36.02%. The two level indicators "sports teacher quality", "physical activity awareness", "self-efficacy" top three.(2) according to the index system developed youth physical activity environment checklist. Through the questionnaire obtained The Cronbach’s alpha of the total were 0.901, The Cronbach’s alpha of four established levels were 0.783,0.795,0.671, 0.799, showed that scale dimensions and total reliability. Surface validity questionnaire, the results of principal component analysis showed that 6 factors explained 62.16% of the variance.Conclusion:This study on the basis of theoretical analysis, established a youth physical activity environment evaluation index system and weight system. One class index "school environment" weight the first, reflects the core of promote adolescent physical activity.
