青少年同伴支持与体育学习投入的关系:自尊和锻炼自我效能感的链式中介

The Relationship between Adolescent Peer Support and Physical Education Learning Engagement:a Chain Mediated Relationship Between Self-Esteem and Exercise Self-Efficacy

青少年体质健康水平正呈逐年下降的趋势,制约着青少年的身心发展。本研究从积极心理学的角度,探讨初中生在体育课堂中的同伴支持对体育学习投入的影响,并考查自尊和锻炼自我效能感在其中的作用。使用《同伴支持量表》、《锻炼自我效能感量表》、《自尊量表》和《UWES-S学习投入量表》对539名初中生进行测量,并对变量进行相关分析和结构方程模型检验。相关分析结果显示:同伴支持、自尊、锻炼自我效能感和体育学习投入三个维度间均存在显著正相关。结构方程模型结果显示:同伴支持可以直接预测体育学习投入,直接效应为0.163;自尊在同伴支持和体育学习投入间起中介作用,间接效应为0.073;锻炼自我效能感在同伴支持和体育学习投入间起中介作用,间接效应为0.236。自尊和锻炼自我效能感在同伴支持和体育学习投入间起链式中介作用,间接效应为0.042。

The level of physical fitness among adolescents is showing a declining trend,which hinders their overall development.This study examines the influence of peer support in physical education classes on the engagement of junior high school students,taking into account the mediating roles of self-esteem and exercise self-efficacy from the perspective of positive psychology.A total of 539 junior high school students were measured using the Peer Support Scale,Exercise Self-Efficacy Scale,Self-Esteem Scale,and UWES-S Engagement Scale.Correlation analysis and structural equation modeling were conducted to analyze the variables.The results of the correlation analysis indicated significant positive correlations among peer support,self-esteem,exercise self-efficacy,and engagement in physical education.The structural equation modeling results revealed that peer support directly predicted engagement in physical education with a direct effect of 0.163.Self-esteem mediated the relationship between peer support and engagement with an indirect effect of 0.073.Exercise self-efficacy also mediated the relationship between peer support and engagement with an indirect effect of 0.236.Furthermore,self-esteem and exercise self-efficacy acted as sequential mediators in the relationship between peer support and engagement with a serial indirect effect of 0.042.
