| Abstract |
The Japanese CADL (JCADL) has been used to measure communication disabilities in people with aphasia. The correlation coefficient between the JCADL total score and measures of impairment, such as the Test for Differential Diagnosis of Aphasia and the Standard Language Test for Aphasia (SLTA), was reported to be quite high. However, a longitudinal study focusing on the relationship between impairment and disability measures has not been undertaken. This study aims to reveal the relationship over time between the performances on the JCADL and the SLTA in 32 subjects with aphasia. The SLTA and the CADL tests were administered at three points during the rehabilitation period. The results of the tests at these three points revealed concomitant improvement over time. In order to identify the factors that influenced improvement in the JCADL test for persons with severe aphasia, two types of data were analyzed: (1) the change in the patterns of each modality score (SLTA), and (2) the type and the number of compensatory strategies and the context in which they were used (CADL). The results indicated interactive effects between linguistic impairment and communication disability. Furthermore, the type of aphasia influenced the number of nonverbal compensatory responses, that is, the subjects with fluent aphasia used less nonverbal compensatory strategies as compared to the subjects with nonfluent aphasia. It was suggested that using the results of the JCADL and SLTA tests together with the information about the type of aphasia may yield useful cues for therapeutic intervention. |
