| The health problems of teenagers have always been widely concerned.Nowadays,physical problems such as myopia,obesity and scoliosis,as well as psychological problems such as depression,anxiety and psychological disorders caused by lack of physical activities have become serious threats to their health.And sports as an important means to promote health has been widely accepted and recognized by all sectors of society.The State Council put forward the youth sports"health package" is a practice to make full use of the means of sports to promote youth health."Content production" is ubiquitous in the social media era,and its cost-effectiveness advantage for large-scale health promotion is particularly obvious.Various social media sports content production platforms are favored by the majority of teenagers because of their intelligence,digitalization,personalization and interaction,and become one of the important ways to promote youth sports and health.Based on the above facts,this paper uses literature method,interview method,questionnaire survey method,mathematical statistics method,experimental method,logical analysis and other research methods,take Self-presention theory,Social Cognitive Theory,Media-system dependency theory and health promotion model as the theoretical basis,try to explore social media content production and the relationship between the youth sports health promotion,and the influence mechanism.It is mainly divided into the following three sub-studies:Study 1:compilation and revision of measurement tools to provide reliable measurement tools for subsequent studies;Study 2:The influence of social media content production on adolescent sports health promotion;Study 3:The influence mechanism of social media content production on adolescent sports health promotion.Through the above research,the main research results of this paper are as follows:(1)Through exploratory factor analysis and confirmatory factor analysis,the Questionnaire on Social Media Content Production for Adolescents was compiled.The questionnaire was composed of two dimensions,user generated content(UGC)and professional generated content(PGC),with a total of 9 questions,among which UGC included 5 questions and PGC included 4 questions.The internal consistency coefficient of the questionnaire was 0.883.The retest reliability was 0.792;The Youth Sports Health Promotion Questionnaire is composed of sports cognition,sports emotion and sports behavior,with a total of 28 items,including 9 items of sports cognition,9 items of sports emotion and 10 items of sports behavior.The internal consistency coefficient of the questionnaire is 0.958,and the retest reliability is 0.832.(2)The causality relationship between the intervention mode of social media content production and adolescent physical health promotion was explored by using the research method of Solomon’s four groups experiment.The four groups of posttest groups(O2,O4,O5,O6)were analyzed by means of the variance analysis of the four groups of mean design,and then the comparison was made according to LSD-t method.As can be seen from the results,the analysis of the 4 formulation differences is statistically significant,P≦ 0.05.Note The mean values of each group are different.Combined with the mean values,we can see that O2>O4>O5>O6.(3)The influence mechanism of social media content production on adolescent physical health promotion was explored through structural equation model.The path coefficient of social media content production affecting adolescent physical health promotion was 0.255,p<0.001;The path coefficient of the influence of network social support on adolescent physical health promotion was 0.368,p<0.001;The influence path coefficient of social media content production on network social support is 0.628,p<0.001;The path coefficient of positive psychological capital on adolescent physical health promotion was 0.582,p<0.001;The influence path coefficient of social media content production on positive psychological capital is 0.422,p<0.001;The path coefficient of influence of network social support on positive psychological capital is 0.379,p<0.001.(4)In the path of social media content production--online social supportpositive psychological capital--adolescent physical health promotion,the relationship between online social support and positive psychological capital on social media content production and adolescent physical health promotion has an intermediary utility rate of 63%.The conclusions of this study are as follows:(1)The Questionnaire is composed of two dimensions,UGC and PGC.With good reliability and validity,the questionnaire is a reliable and effective measurement tool,which can be used as a tool to measure the content production of teenagers’social media.The Youth Sports Health Promotion Questionnaire is composed of three dimensions of youth sports cognition,sports emotion and sports behavior.With good reliability and validity,the questionnaire is a credible and effective measurement tool,which can be used as a tool to measure youth sports health promotion.(2)The main effect of intervention mode of social media content production was significant.The level of physical health promotion of adolescents in the intervention group witih social media content production was significantly better than that in the non-intervention group.(3)Social media content production can directly predict the level of adolescent physical health promotion.UGC and PGC can improve the level of sports health promotion by influencing teenagers’ sports cognition,sports emotion and sports behavior.Growing up in the digital age,teenagers generally have a natural sense of social media.Therefore,in the practice of youth sports health promotion,we should give full play to the positive role of social media content production.(4)Online social support plays a mediating role in the effect of social media content production on adolescent physical health promotion.The tool support,information support,friend support and emotional support of network social support all play an important role in improving the level of adolescent physical health promotion.Therefore,when promoting youth sports health,relevant departments should attach importance to the role of network social support,guide youth to take the initiative to participate in sports and carry out healthy self-management based on their needs.(5)Positive psychological capital plays a mediating role in the effect of social media content production on adolescent physical health promotion.Most adolescents have correct sports health cognition,but due to various reasons can not be implemented into action,positive psychological capital and its components(optimism,hope,resilience and self-efficacy)can help adolescents to overcome difficulties in sports,start and maintain sports behavior.(6)The chain mediating effect of online social support--positive psychological capital plays an important role in the process of social media content production promoting youth physical health.It can be seen that the promotion of youth sports health by social media content production is mainly achieved with the help of the network social support and the improvement of positive psychological capital.Therefore,in the practice of promoting youth sports health,the relevant departments should pay attention to the development and cultivation of the positive psychological capital elements of teenagers,cultivate their optimistic spirit and enhance their resilience to resist pressure.Based on the relevant research results of social media content production,online social support,positive psychological capital and adolescent physical health promotion,this study compiled and revised the research tools,and confirmed the causal relationship between the intervention mode of social media content production and adolescent physical health promotion through the Solomon experimental study.Then,a mechanism model of the influence of social media content production on adolescent physical health promotion was constructed,the relationship between variables was demonstrated,and the mediating effect of online social support and positive psychological capital was explored.The conclusion of this study can provide the basis for the relevant theoretical and practical research of adolescent physical health promotion,and also is the development and complement of relevant theories,which has certain theoretical and practical significance. |
