Abstract

The Communication Analysis System (CAS) was developed to facilitate efficient, effective treatment of conversational performance for persons with aphasia. The CAS provides frequent, objective, accurate, ratio-quality measures of ten classes of communicative behaviors for the patient and 11 for the clinician. The clinician using the CAS records the time of occurrence of communicative behaviors by a single keystroke on a keypad attached to an inexpensive microcomputer. The CAS software permits the analysis of data before the next clinical session and includes a method for assessing accuracy and reliability. Sample between-session data show the progress of one patient over several months, whereas within-session data illustrate a use of the CAS to measure a patient's performance under different communicative conditions. Simultaneously, measures of the clinician's communicative performance provide an accurate record of the treatment. This, in turn, allows observation of changes in the patient's behavior as a function of changes in the clinician's behavior. Clinical treatment can thereby be tailored precisely to the individual, optimizing the patient's rehabilitation.
