群体变量对成员锻炼坚持性影响的多层线性分析

A hierarchical linear analysis of the effects of group variables on member exercise adherence

以52个有组织的锻炼群体共601名锻炼成员为研究对象,运用分层线性模型分析技术,主要考察锻炼群体的样本特征、凝聚力、领导行为等变量,在群体水平上对成员锻炼坚持性的影响。结果表明:个体锻炼坚持性存在显著的群体差异,个体锻炼坚持性的总体变异有12.8%由群体差异造成;锻炼群体的成立时间、凝聚力与领导行为等因素是影响成员锻炼坚持性的重要群体变量;群体成立时间、群体凝聚力与领导行为,对成员锻炼坚持性的群体变异均具有较大的解释率和显著的正向预测作用。

By basing their research objects on totally 601 exercise members from 52 organized exercise groups, andby applying hierarchical linear model analysis techniques, the authors mainly examined the effects of such variablesas the sample characteristic, cohesion and leading behavior of the exercise groups on member exercise adherence atthe group level, and revealed the following findings： individual exercise adherence has a significant group difference：12% of the total variance of individual exercise adherence is caused by group difference; such factors as exercisegroup establishment time, cohesion and leading behavior are important group variables that affect member exerciseadherence; group establishment time, group cohesion and leading behavior have a higher explanation rate anda significant positive prediction function on the group variance of member exercise adherence.
