Physical activity behavioral intentions have a positive impact on individuals' physical and mental health, social adjustment, and academic work. This study explored the effects of peer relationships on college students' behavioral intentions for physical activity and analyzed the mediating role of social support and exercise self-efficacy.
The Peer Relationship Inventory, the Physical Activity Rating Scale-Intentions to Physical Activity Behavior subscale, the Social Support Scale, and the Exercise Self-Efficacy Scale were used to psychometrically measure 514 college students (age = 19.00 ± 1.27) from June 3, 2024, to June 7, 2024, and the Bootstrap method was used to mediate the relationship between social support and exercise self-efficacy.
(1) Peer relationships, social support, exercise self-efficacy and intention to engage in physical activity behaviors were positively correlated (all p < 0.01); (2) gender differences in exercise self-efficacy and intention to engage in physical activity behaviors existed (p < 0.001), and male students scored higher than female students (M ± SD: 3.18 ± 0.55 > 2.98 ± 0.59; 3.23 ± 0.62 > 2.95 ± 0.61); (3) the mediating effect size of social support (peer relationship→social support→behavioral intention to exercise) was 0.078, which accounted for 8.83% of the total effect, and that of exercise self-efficacy (peer relationship→exercise self-efficacy→behavioral intention to exercise) was 0.314, which accounted for 35.56% of the total effect, the chained mediation effect of social support and exercise The chain mediation effect size of self-efficacy (peer relationship→social support→exercise self-efficacy→behavioral intention to exercise) was 0.057, accounting for 6.46% of the total effect, and none of the confidence intervals contained 0.
(1) College students' peer relationships can significantly and positively predict behavioral intention to exercise; (2) college students' peer relationships can have a simple influence on the behavioral intention to exercise through social support and exercise self-efficacy, respectively; (3) College student peer relationships can also influence intention to engage in physical activity through social support and exercise self-efficacy in a chained manner.
身体活动行为意向对个体的身心健康、社会适应和学业表现具有积极影响。本研究探讨同伴关系对大学生身体活动行为意向的影响，并分析社会支持和运动自我效能感的中介作用。
于2024年6月3日至2024年6月7日，使用同伴关系量表、身体活动评定量表-身体活动行为意向分量表、社会支持量表和运动自我效能量表对514名大学生（年龄 = 19.00 ± 1.27）进行心理测量，并采用Bootstrap方法对社会支持和运动自我效能感之间的关系进行中介分析。
（1）同伴关系、社会支持、运动自我效能感与参与身体活动行为的意向呈正相关（均p < 0.01）；（2）运动自我效能感和参与身体活动行为的意向存在性别差异（p < 0.001），男生得分高于女生（M ± SD：3.18 ± 0.55 > 2.98 ± 0.59；3.23 ± 0.62 > 2.95 ± 0.61）；（3）社会支持的中介效应量（同伴关系→社会支持→运动行为意向）为0.078，占总效应的8.83%，运动自我效能感的中介效应量（同伴关系→运动自我效能感→运动行为意向）为0.314，占总效应的35.56%，社会支持和运动自我效能感的链式中介效应量（同伴关系→社会支持→运动自我效能感→运动行为意向）为0.057，占总效应的6.46%，且所有置信区间均不包含0。
（1）大学生的同伴关系能够显著正向预测运动行为意向；（2）大学生的同伴关系可分别通过社会支持和运动自我效能感对运动行为意向产生简单影响；（3）大学生同伴关系还可通过社会支持和运动自我效能感以链式方式影响参与身体活动的意向。
