县域学龄儿童自我效能感与体力活动的关系:锻炼身份认同的中介作用

Associations between self-efficacy and physical activity in school-aged children:The mediating role of exercise identity

探索学龄儿童的自我效能感与体力活动间的关系及锻炼身份认同在其中发挥的中介作用。采用儿童体力活动问卷(PAQ⁃C)、一般自我效能感量表(GSES)、锻炼身份认同量表(EIS)等对江苏省南通市和甘肃省平凉市两所县域内小学的3~6年级小学生进行调查。结果显示,男生、低年级、非独生子女及西部地区的小学生体力活动水平更高。样本小学生的自我效能感与体力活动水平呈正相关关系;锻炼身份认同在自我效能感和体力活动之间起部分中介作用,且中介效应占比为59.3%。这在一定程度上解释了儿童青少年自我效能感和体力活动之间的内在影响机制,可为儿童青少年体力活动干预提供理论和实践依据。

This study aims to explore the relationship between self-efficacy and physical activity among school-aged children,along with the mediating role of exercise identity by utilizing the Physical Activity Questionnaire for Children(PAQ-C),General Self-Efficacy Scale(GSES)and Exercise Identity Scale(EIS)to investigate 3rd to 6th grade students of two primary schools in Nantong City,Jiangsu Province and Pingliang City,Gansu Province.The results showed that physical activity score was higher in males,younger students,non-only-child,and students from the western region.There was a positive correlation between self-efficacy and physical activity levels.The exercise identity played a partial mediating role between self-efficacy and physical activity,accounting for 59.3%.This study partially explains the intrinsic mechanism between children and adolescents’self-efficacy and physical activity,providing a theoretical and practical basis for physical activity intervention among children and adolescents.
