Purpose: 1) To investigate the clinical applicability and validity of the Korean CADL (Communicative Abilities in Daily Living) in evaluating the functional language abilities. 2) To assess the features of the aphasic patients after stroke.
Method: The Korean CADL and Boston Diagnostic Aphasia Examination (BDAE) were applied to 20 normal controls and to 20 stroke patients with aphasia.
Results: 1) Each categorical and total CADL scores of aphasic patients were significantly lower than those of normal controls. 2) Total CADL scores of aphasic patients were highly correlated with total scores of the BDAE. 3) Total CADL scores of normal controls were not significantly different in both sexes, but in aphasic patients case, those of males were significantly higher than those of females. 4) Scores of CADL & BDAE were high in order of anomic, expressive, receptive, and global aphasia.
Conclusion: The Korean CADL appeard to be a valid and reliable method in measuring the functional communicative abilities of the aphasic patients after stroke.

In order to investigate the acquisition and functional use of a mode interchange skill in severely aphasic patients, experimental training was conducted with a single-subject multiple-baseline across subjects design.
Methods: Four severely aphasic subjects underwent three phases of experimental training. In the first phase, the subjects were trained to acquire two expression modes: gesture and drawing. In the second phase, the subjects were trained through a paradigm of an "incorrect item offer" in a request situation. This procedure was known to induce mode interchange behavior in mentally retarded subjects. The subjects were required to convert to another communication mode when the first attempt to convey his/her request failed. The third phase was a probe test for generalization.
Results: Three of the four subjects were able to acquire the two modes. All three subjects needed additional training using prompt signs to induce mode interchange, and one of them needed a prompt sign fading procedure.
Conclusions: The results of a probe test indicated the importance of "waiting behavior" on the part of familiar communication partners to facilitate the use of the skill.
