■本研究通过运动氛围和运动自我效能感的中介作用,探讨了大学生身体活动动机与运动行为之间的关系,并构建了连锁中介模型。
■通过随机抽样,使用锻炼动机量表对1032名大学生进行了调查,体育锻炼评定量表,运动气候量表,和运动自我效能感量表。
■(1)运动动机与运动行为之间存在巨大的正相关(r=0.240,p<0.01),将运动动机与运动行为联系起来的直接方式至关重要(β=0.068,t=0.040,p<0.01)。(2)运动动机能正向预测运动氛围(β=0.373,t=0.061,p<0.01)和运动自我效能(β=0.174,t=0.039,p<0.01);运动气候可以很好地预见运动行为(β=0.302,t=0.051,p<0.01)。运动自我效能感可以明确地预测运动行为(β=0.190,t=0.048,p<0.01)。(3)运动氛围和运动自我效能感在运动动机和运动行为之间起重要的干预作用。代言影响明确地来自三种方式产生的异常影响:运动动机→运动气氛→运动行为(中介效应值:0.113);运动动机→运动自我效能感→运动行为(中介效应值:0.033);运动动机→运动气氛→运动自我效能感→运动行为(中介效应值:0.027)。
■(1)运动气候,锻炼自我效能感,运动行为都可以通过运动动机来显著预测,这表明运动动机可能有助于增强这些变量。(2)除了对锻炼行为有直接影响外,运动动机还可以通过运动氛围和运动自我效能感的独立中介效应以及运动氛围和运动自我效能感的连锁中介效应产生间接影响。这对于鼓励大学生进行体育锻炼至关重要。
UNASSIGNED: This study explored the relationship between college students\' physical activity motivation and exercise behavior and constructed a chain mediation model through the mediating roles of exercise climate and exercise self-efficacy.
UNASSIGNED: By random sampling, 1,032 college students were investigated using the Exercise Motivation Scale, Physical Exercise Rating Scale, Exercise Climate Scale, and Exercise Self-Efficacy Scale.
UNASSIGNED: (1) There was a huge positive correlation between exercise motivation and exercise behavior (r = 0.240, p < 0.01), and the immediate ways of linking exercise motivation to exercise behavior were critical (β = 0.068, t = 0.040, p < 0.01). (2) Exercise motivation could positively predict exercise climate (β = 0.373, t = 0.061, p < 0.01) and exercise self-efficacy (β = 0.174, t = 0.039, p < 0.01), and exercise climate could emphatically foresee exercise behavior (β = 0.302, t = 0.051, p < 0.01). Exercise self-efficacy could foresee exercise behavior decidedly (β = 0.190, t = 0.048, p < 0.01). (3) Exercise climate and exercise self-efficacy play a critical intervening role between exercise motivation and exercise behavior. The intercession impact is explicitly made out of aberrant impacts created in three ways: exercise motivation → exercise climate → exercise behavior (mediating effect value: 0.113); exercise motivation → exercise self-efficacy → exercise behavior (mediating effect value: 0.033); exercise motivation → exercise climate → exercise self-efficacy → exercise behavior (mediating effect value: 0.027).
UNASSIGNED: (1) Exercise climate, exercise self-efficacy, and exercise behavior can all be significantly predicted by exercise motivation, suggesting that exercise motivation may help to enhance these variables. (2) In addition to having a direct impact on exercise behavior, exercise motivation can also have an indirect impact through the separate mediating effects of exercise climate and exercise self-efficacy as well as the chain mediating effect of exercise climate and exercise self-efficacy, which is crucial for encouraging college students to engage in physical activity.
