「Rosenberg 自尊量表」之試題衡鑑：評等量尺模型的應用

Evaluation of the Rosenberg Self-Esteem Scale Using the Rating Scale Model

「Rosenberg自尊量表」旨在測量個人的自尊狀態，為一廣受歎迎與使用的自 陳式測量工具。本研究的目的旨在透過Rasch測量家族的評等量尺模式，檢視 「Rosenberg自尊量表」的心理計量特性。本研究探用ConQuest 2.0套装軟體進行 評等量尺模式分析，研究樣本計有1，155名臺灣國中生。研究結果顯示，「Rosenberg 自尊量表」較適合用來精確區分出中等程度自尊的受試者，但對於自尊特質 量尺兩端的受試者，其測量精確度較低。本研究除針對評等量尺模式在量表發展上 的應用予以探討外，並依據結果進行討論，以提出後續研究之相關建議。

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.
