聽覺中樞處理功能測驗之發展

The Development of the CentralAuditory Processing Test Battery

本研究旨在發展一套評量聽覺中樞處理功能的測驗，測驗選取係以美國聽語學會2005 年提出之聽覺中樞處理功能新定義為依據，各測驗均採非語音、最簡約及電腦作答原則編製，包括頻率分辨、間隔察覺、音高型態辨識、時長型態辨識、雙耳異訊音高及聽覺辨位等六項測驗。研究對象為國小三年級聽覺正常兒童，包括預試樣本30 人、正式施測樣本100 人、重測與效標效度樣本31 人。研究顯示聽覺中樞處理功能測驗之內部一致性介於.83 到.94 之間，相隔十週後之重測信度介於.41 到.88 之間，且得分不受試題呈現先後次序的影響；在效度部分包括專家效度、效標效度、透過因素分析以及驗證性因素分析取得之構念效度之證據。本研究依據上述各項研究結果，針對實際在臨床施測與解釋提出各項建議。

The purpose of the study is to develop the Central Auditory Processing Test Battery (CAPTB). The six tests were chosen according to the definition made by American Speech-Language-Hearing Association in 2005. Test composition followed these principles: First， non-speech materials were adopted as the stimuli; second， the test was designed as a computer-assisted system， in which low level of effort was required of subjects to make responses. Participants were 3rd graders with normal hearing， including 30 for pre-testing， 100 for formal testing， and 31 for re-test and criteria validity test. The CAPTB included frequency discrimination， gap detection， pitch pattern recognition， duration pattern recognition， dichotic pitch， and lateralization tests. The main results were as follows: (1) The internal consistency reliability ranged from .83 to .94， and the test-retest correlation coefficient of test scores was between .41 and .88; (2) The expert validity， criterion-related validity， and construct-related validity were satisfactory. Suggestions for the application of the CAPTB and future research were offered and discussed.
