| Summary: | 碩士 === 國立臺北護理健康大學 === 語言治療與聽力研究所 === 106 === This study aims to initially measure the reliability and validity of the Assessment of Auditory Perception for Conceptual Recognition (AAPCR; including the two subtests of Test 1 & Test 2—T1 & T2) in patients with neurological brain damage. There were 40 neurologically- impaired patients and 39 controls matched by age and education in the study (Mean age and Education years：Patients= 55.1 & 12.3; Controls= 53.8 & 11.9). All participants received a screening test of the Montreal Cognitive Assessment-Taiwanese version (MoCA-T) and the AAPCR. Test-retest reliability, internal reliability, construct validity, and criterion related validity were applied to establish the clinical effectiveness of the tool. KR 20 and Pearson’s correlation were used to measure the psychometrics of the AAPCR. The results demonstrated consistent responses, test reliability and a high correlation among the scores obtained from T1 and T2 subtests, and the AAPCR, as well as meeting the consistency with the results of the MoCA-T in both groups. With the exceptions found in control group, low internal consistency and mild correlation in T1 and MoCA-T were noted. Using an optimal cut-off score of 55, the AAPCR had a sensitivity 89.5% and acceptable specificity of 65% for detecting a disorder of central conceptual structures and/or perceptual deficit post brain damage, especially for patients post stroke. These findings indicate the AAPCR has good psychometrics and could be a valid and reliable tool for detecting a mild to moderate -severe disorder of central conceptual structures in neurologically-impaired patient populations.
