本研究根據理論與相關研究提出高職階段中度智能障礙學生自我概念與自我 擁護模式，該模式假設個體的自我概念與自我擁護具有關聯性。本研究自編學生 自評與導師評量兩種問卷，調查臺灣地區347 位高職階段中度智能障礙學生與116 位導師，其中，學生自評問卷的填答類型是融合雙重二分法及圖示等級量表兩種 形式來呈現，導師評量和學生自評的問卷並非同一份問卷，題意維持相同，將題項 的主詞改成「學生」並且移除溝通圖，填答類型與計分方式是採用李克特四點量 尺。本研究目的為檢定自我概念與自我擁護模式在學生自評與導師評量群體之間 結構恆等性，了解中度智能障礙學生自評問卷的可行性。本研究運用結構方程模 式進行分析，研究結果發現所建構的高職階段中度智能障礙學生自我概念與自我 擁護關聯模式得到驗證與支持，而且自我概念與自我擁護模式在高職階段中度智 能障礙學生自評與導師評量群體之間具有結構恆等性，表示高職階段中度智能障 礙學生自評與導師評量學生自我概念與自我擁護關聯模式的整體架構是一致的。 從這些方面來看，高職階段中度智能障礙學生自評問卷是可以接受的。最後，根 據研究結果提出各項建議，以供高職階段中度智能障礙學生、家長、教師與輔導 工作者實務上及未來研究參考。

Purpose: Based on relevant theories and earlier studies, this study proposed a “selfconcept and self-advocacy model” of high school vocational students with moderate intellectual disabilities (IDs). This model assumed that an individual’s self-concept and self-advocacy are correlated. This study (a) developed self-concept and self-advocacy questionnaires for high school vocational students with moderate IDs; (b) evaluated the compatibility of the collected data and the theoretical model proposed in this study through confirmatory factor analysis and structural equation modeling; and (c) examined the structural invariance across groups. Methods: The initial item pool was developed based on a review of relevant literature and tools. The self-concept and self-advocacy questionnaires comprised 2 scales: the student rating scale (SRS) and teacher rating scale (TRS). Item analyses were used to delete inadequate items and establish reliabilities and validities. Both the SRS and TRS comprised 38 items from the self-concept and selfadvocacy scales. The format scale response of the self-concept and self-advocacy were adapted for students with moderate IDs. Two versions of the SRS were used, and two alternative response scale formats were developed: double binary and graphical. The TRS used a 4-point Likert-type scale. Samples were collected using stratified sampling. A total of 347 high school vocational students with moderate IDs who attended special schools and 116 of their teachers were involved in the study. Results /Findings: The study yielded the following results: (a) the content validity was established by consulting experts and exploring documents; (b) regarding internal consistency, both the SRS and TRS yielded extremely high coefficients (composite reliability); (c) a structural equation model was adopted to examine the factor structure of the “SRS and TRS for high school vocational students with moderate IDs, and the results indicated that this scale performed effectively in the following three categories: the preliminary fit, overall model fit, and the fit of the partial internal structural model; and (e) the evidence of structural invariance indicated that the hypothesized self-concept and self-advocacy model generally fit the data; the main structure and factor loadings were generally invariant across groups. This study supported the structural invariance of the assumed model between the student and teacher rating groups in Taiwan. Conclusions/Implications: Based on the results, the self-concept and self-advocacy questionnaires had acceptable indicator reliability and validity values. The psychometric findings indicated that the proposed questionnaires were suitable for gathering information from students and teachers regarding self-concept and self-advocacy. Therefore, we concluded that self-concept and self-advocacy dimensions have the same meaning among high school vocational students with moderate IDs and teacher groups. The implications of the results are discussed, and suggestions are made regarding high school vocational students with moderate IDs, parents, teachers, vocational high school counselors, and future research.
