博士 === 國立高雄師範大學 === 特殊教育學系 === 107 === Individuals with intellectual disabilities (ID) have communicative difficulty in their lives, but there is no applicable language test in Mandarin for adults with ID. The study investigated the application of Concise Chinese Aphasia Test (CCAT) in the adults with ID. Also, the author offset six supplementary tests against the shortcomings of CCAT: Peabody Picture Vocabulary Test (PPVT), Mandarin Token Test (MTT), Similarity, Information, Vocabulary, Comprehension [the four latter tests belong to Wechsler intelligence scale for children-fourth edition (WISC-IV)]. The author verified these tests had acceptable reliabilities and validities for adults with ID. Ninety-four subjects with ID participated in the investigation. The results indicated that there was a high split-half reliability and intra-consistency in CCAT. The interrater reliability showed a strong degree of .883~.993. The analysis in discriminative validity proved that CCAT could differentiate among the severity of disabilities and from employment/nonemployment. The results from supplemental tests also revealed that they had high reliability coefficient in all six tests. In addition, the discriminative validity was well. According to the factor analysis, the complementation between CCAT and the supplemental tests was approved. In summary, CCAT was an applicable test for adults with ID. Furthermore, the additional tests could appropriately assess the language abilities in adults with ID. As a result, CCAT could combine with the supplemental tests to become a kit of language test, CCAT+, for adults with ID.
