0-5, 5 being normal, 0 being no speech output or auditory comprehension
Rating Scale Profile of Speech Characteristics

Subtest Scoring and Summary Profile
Computation of Language Competency Index
Overall measure of aphasia severity
Based on fluency, auditory comprehension and naming subtest scores
"Cookie Theft" Picture Description
Recent Revision
Third Edition - 2001
Added short and extended version (timing)
Incorporated Boston Naming Test as subtest in 1983
Addition of Language Competence Index
Integrated recent advances in neurolinguistic research
Standard form is more closely related to earlier version
Short form is "no frills"
Extended offers full neurolinguistic assessment
Test-Retest Reliability
BDAE - No Data
BNT - High over short intervals and mixed results over long intervals
Inter-Rater Reliability
BDAE - Satisfactory Results; variable based on study
Internal Consistency
BDAE - generally acceptable to high; variability among subtests
BNT - Very High
Validity
Deemed valid, one of the most widely used Aphasia tests
No sensitivity or specificity data provided
BDAE -
Provide language assessment for aphasia and related disorders
To enable a diagnosis of aphasia syndromes
Provide measure of strengths and weaknesses in both receptive and expressive language and communication abilities
Provide guidance for prognosis and treatment
BNT - assess vocab skills and visual object naming in children and adults
