Background & Objectives
Essentials to the notion of routine aphasia evaluation at the bedside are efficiency of test administration as well as discriminative validity of measures. An aphasia screening test might satisfy the two conditions but existing aphasia screening tests have failed to verify content validity of test items. Thus, this study aimed to evaluate the content validity of aphasia tests and to propose test items of an aphasia screening test based on the evaluation.
After analyzing the subtests of the aphasia assessment tools and aphasia screening tests, Content Validity Index(CVI) was calculated based on CVI of the test items judged by seven speech-language pathologists.
It was found that CVIs of the test items of the newly developed aphasia screening test were above .60 and thus the items were thought to be suitable to detect aphasia.
Discussion & Conclusion
Aphasia screening test with optimal level of CVI of test items would serve as an appropriate screening test for detecting aphasia. A significance of this study was to provide content validity of test items as preliminary data in standardizing an aphasia screening test.
