成人失語症功能性溝通評估工具之編制

本研究目的為編制符合國人日常生活情境之功能性溝通評估工具並檢驗其信效度。 研究分為兩階段進行：研究一為編制成人失語症功能性溝通評估工具，並進行專家效度審查及題目修正，再由4名正常及4名失語症受試者進行預試，並依評估結果及受試者回饋再度進行修正，最後完成正式施測版本。研究二則招募14名失語症個案進行本研究編制之成人失語症功能性溝通評估工具的施測，進行信效度分析。 信度分析結果顯示，本研究編制之成人失語症功能性溝通評估工具，分測驗及全測驗內部一致性高（Cronbach’s alpha = 0.86~0.95），評分者間信度ICC值皆為1.0，評分者內信度ICC值皆高於0.9，均達極佳之信度水準。效度部分，各分測驗與全測驗之相關程度皆達中度相關以上（Kendall tau = 0.66~0.94），具建構效度；另與簡明失語症（CCAT）具高度相關（Kendall tau = 0.77），顯示具有效標關聯效度。 整體而言，本研究編制之成人失語症功能性溝通評估工具具備良好信效度，未來可供臨床評估或學術研究使用，以增加國內評估功能性溝通能力的便利性。

The aim of the study was to develop a functional communication assessment tool for people with aphasia, which applies to the daily activities in Taiwan, and to evaluate its validity and reliability. The study was conducted in two phases. The main purpose of study one was to establish the Functional Communication Assessment for Adults with Aphasia. The pretest version was established after expert panel review and multiple revisions, and was administered to 4 healthy and 4 aphasic participants. Revision was conducted again according to test results and feedback received from participants, and then the final version of the Functional Communication Assessment for Adults with Aphasia was accomplished. In study two, a total of 14 participants with aphasia were administered the Functional Communication Assessment for Adults with Aphasia, and the validity and reliability of this new evaluation tool was assessed. The Functional Communication Assessment for Adults with Aphasia demonstrated high level of internal consistency (Cronbach’s alpha = 0.86~0.95), excellent inter-rater reliability (ICC = 1.0) and intra-rater reliability (ICC = 0.965~0.999). In addition, correlation between whole-test and subtests was moderate to high (Kendall tau = 0.66~0.94), indicated acceptable construct validity. Correlation between the Function Communication Assessment for Adults with aphasia and the Concise Chinese Aphasia Test (CCAT) revealed a good criterion-related validity (Kendall tau = 0.77). In summary, results of this study suggested that the Functional Communication Assessment for Adults with aphasia displayed satisfactory validity and reliability that may be used in clinical settings or related research, and may enhance the convenience of assessing functional communication in aphasic adults in Taiwan as well.
