We examined the equivalence of videoconferencing assessment of communication by speech-language pathologists (SLPs). Using a randomized, double-crossover agreement study, 24 post-stroke patients were randomized to a remote or face-to-face administration of a subset of the Boston Diagnostic Aphasia Examination and to remote or face-to-face assessment of speech comprehension, speech expression and motor speech. The videoconferencing equipment was operated at a transmission speed of 384 kbit/s. Each patient was simultaneously scored by both the face-to-face and the remote SLPs. SLPs were blind to each other's results. Percentage agreement within the 95% limits of agreement ranged from 92% to 100% for each functional communication measure, regardless of assessment site and administration of the aphasia examination. The results suggest that assessment of a patient's functional communication using videoconferencing is equivalent to a face-to-face encounter.
