The aim of the study was to modify the Amotivation Toward Exercise Scale-2 by dropping the outcome amotivation beliefs subscale while retaining the capacity, effort, value, and task characteristics amotivation beliefs. Data from 515 Greek nonexerciser adults aged 19-64 years and 399 Greek nonexerciser older adults aged 65-82 years, men and women, supported the latent four-factor structure of the Revised Amotivation Toward Exercise Scale-2 scores within each sample separately. The hierarchical model was also supported. Measurement invariance of Revised Amotivation Toward Exercise Scale-2 scores was supported across groups of gender, age, body mass index, and educational levels within adults and older adults. Configural measurement invariance supported a replicable factor structure across adults and older adults. Metric and strong invariance was supported across middle-aged and older adults but not between younger and older adults. Full measurement invariance was supported between younger and middle-aged adults.
本研究旨在修改运动动机量表-2，删除结果动机信念分量表，同时保留能力、努力、价值和任务特征动机信念。来自 515 名希腊非运动成年人（19-64 岁）和 399 名希腊非运动老年人（65-82 岁）的男性和女性的数据分别支持了修订后的运动动机量表-2 评分在每个样本中的潜在四因素结构。分层模型也得到了支持。在成年人和老年人中，性别、年龄、体重指数和教育水平的群体中，修订后的运动动机量表-2 评分的测量不变性得到了支持。配置测量不变性支持了成年人和老年人之间可重复的因子结构。中老年人的度量和强不变性得到了支持，但年轻人和老年人之间的不变性则没有得到支持。年轻人和中年成年人之间的完全测量不变性得到了支持。
