The Academic Motivation Scale (AMS) is a commonly used 28‐item measure of motivation orientation. However, the scale has not been examined using methods to distinguish between state and trait aspects of motivation. We applied Generalizability Theory to appraise the psychometric properties of the AMS and to differentiate items measuring state or trait motivation within the AMS.

使用概化理论研究学生动机的稳定和动态方面

学术动机量表（AMS）是常用的28项动机倾向量表。但是，尚未使用区分动机的状态和特质方面的方法来检验量表。我们应用概化理论来评估AMS的心理测量特性，并区分测量AMS内部状态或特质动机的项目。
