Please visit this website for more information about the instrument: Boston Diagnostic Aphasia Exam
Supplemental: Friedreich's Ataxia (FA) and Mitochondrial Disease (Mito)
Short Description of Instrument
The Boston Diagnostic Aphasia Examination - Third Edition (BDAE-3) helps to distinguish between disorders of aphasic syndromes and to provide a comprehensive assessment of language to guide therapy. The test is organized into five major sections: Conservational and Expository Speech; Auditory Comprehension; Oral Expression; Understanding Written Language; and Writing.
Comments/Special Instructions
The short form takes 30 to 45 minutes to complete.
Scoring and Psychometric Properties
Scoring: Scoring is based upon the severity rating scale, the rating scale profile of speech characteristics, and the pattern of performance across subtests and modalities after raw scores have been converted to z-scores.
Psychometric Properties: The normative sample is a stroke population; thus, scores are not normally distributed but negatively skewed.
Strengths: Assesses language comprehensively, including reading and writing; subtests can be used independently.
Weaknesses: Adult only norms, designed to assess aphasia syndromes rather than developmentally based disorders of language.
