The purpose of this study was to examine the use of a descriptive taxonomy for assessment of communicative abilities, the Pragmatic Protocol, in a rehabilitation setting with brain-injured children and adolescents. Eight severely brain-damaged children/youths were assessed with the Pragmatic Protocol during an intensive 6-week rehabilitation period. The nature and extent of communicative functioning was rated independently by a speech language pathologist and a rehabilitation assistant. The data suggests that the number of inappropriate pragmatic behaviours is relatively high, above all regarding aspects of speech/language and nonverbal communication. Interrater agreement reached approximately 95% considering nature of the communicative dysfunction in each patient. Results indicate the use of the Pragmatic Protocol as a useful tool to trace aspects of communicative competence in need of further, detailed exploration. Information concerning intact abilities is clarified and can be used in designing treatment.
