「Rosenberg 自尊量表」之試題衡鑑：評等量尺模型的應用

The Rosenberg Self-Esteem Scale (RSES) is a most popular self-report instrument for evaluating self-esteem and is widely used in many fields. This study examined the psychometric properties of items in RSES with rating scale model (RSM). A sample of 1,155 students in Taiwan was used. By using the software ConQuest 2.0, item and step parameters and their corresponding infit statistics were provided. The results showed that RSES can discriminated the examinees with moderate self-esteem, rather than that in the upper and lower end of the continuum. Psychometric properties and norm values based on the representative sample are reported. Implications of using rating scale model for scale development and evaluation, as well as suggestions for future research, are discussed.
