Abstract
Aphasia is disturbance of any or all of the skill associations, and habits of spoken and written language, produced by injury to certain brain areas specialized for these functions, occurring in a person with a fully developed language system.
In the assessment of aphasia, each component of language should be tested individually and thoroughly including assessments of spontaneous speech, naming, repetition, comprehension, reading, and writing. Assessment of aphasia aims at a comprehensive evaluation for a range of cognitive and psychosocial constructs (as is possible in the available time).The available aphasia tests are not suitable to be applied on Egyptian patients without modification.
The aim of this study is to formulate and apply the Boston Diagnostic Aphasia Examination (BDAE) as a tool for evaluating Egyptian aphasic patients in order to diagnose of the presence and type of aphasia, measure the performance initially and detect change over time and comprehensive assessment of patient’s liabilities in all language areas as a guide of therapy.
BDAE is subdivided into five functional subsections: Conversational and expository speech for assessing functional competence in communication and making formal evaluation of the speech output pattern for severity rating and production of a speech characteristic profile. Auditory comprehension including; word comprehension commands, and complex ideational material test. Oral expression which includes testing of articulation, and automatized speech recitation, melody and rhythm, repetition and naming including the Boston Naming Test. Reading which is a comprehensive evaluation of functional reading in aphasia ranging from symbol recognition of letters and numbers to oral and silent reading comprehensions of sentences and Writing in which thorough evaluation of writing mechanics, dictation and narrative writing. The test also includes an appended Apraxia Assessment. The test contains three forms; in addition to the Standard examiner time and the Extended Test at the examiner’s option, for more probing and evaluation of language functions within each area of testing.
The test was translated and modified the applied on 60 adults, divided into two groups; 30 normal controls and thirty aphasic patients aged from 19-72 years.
Pilot study was done on 10 subjects to check test materials, the order of question administration. Certain modifications were done to suit the Egyptian culture.
Reliability of the test was proven by test retest method with three week interval, and through the internal consistency using reliability coefficient. Validity was proven through content validity, internal consistency validity, known group comparison and convergent validity. All methods indicated that the test is reliable and valid as a test for aphasia evaluation.
Normative scores were expressed in the form of mean, standard deviation, minimum and maximum and cutoff scores.
