A Study on the Effect of Family Support on Adolescent Girls'Sports Participation Level——Analysis Based on Chain Mediation Model
Objective:To understand the factors affecting the participation level of adolescent girls in sports and the relevant mechanisms to form a scientific prevention and intervention program.Methods:1588 middle school girls from 16 regions in China were investigated by stepwise regression method and chain mediation effect was construc-ted to investigate the relationship between family support,out-of-school exercise behavior,in-school exercise behavior and sports participation level of adolescent girls.Results:Family support,in-school exercise behavior and out-of-school exercise behavior predicted the level of adolescent girls'sports participation significantly(B=0.139,t=7.783∗∗;B=0.137,t=4.941∗∗;B=0.195,t=8.756∗∗),the direct effect of family sup-port on sports participation level accounted for 73.99%of the total effect.Ind1:Family support->out-of-school exercise behavior->Sports participation level and Ind3:Family support->out-of-school exercis e behavior->in-school exercise behavior->Sports participation level have significant effects.Conclusion:Family support indirectly predicts the level of adolescent girls'sports participation through the chain mediating effect of out-of-school exercise behavior and in-school exercise behavior.Therefore,with family support as the main driving force,combined with school sports and community sports as the main implementation site,the development of relevant physical health intervention programs to intervene in the physical exercise behavior of adolescent girls in school and outside school,so as to improve the level of sports participation of adolescent girls.
