ASSESSMENT TOOLS FOR APHASIA 2026/2027 | COMPLETE STUDY GUIDE, DIAGNOSTIC TESTS
& EXAM REVIEW
Formal assessment - ANS ✔✔Highly controlled observation using a published quantification tool
to gather information on a person's functioning.
Western Aphasia Battery (WAB) - ANS ✔✔Localization oriented
Score gives Aphasia Quotient that determines type/severity of aphasia
Good test-retest reliability (>.88)
Weaknesses of WAB - ANS ✔✔-Manual and administration weak
-Little linguistic information
-Limited sampling within subtests
-May not be appropriate for higher level patients
Strengths of WAB - ANS ✔✔-Relatively brief administration time (~1 hour)
-Classifies all patients quantitatively
-Provides AQ and CQ
Aphasia Diagnostic Profiles (ADP) - ANS ✔✔Localization based
Provides aphasia classifications
Percentile rank for Overall Aphasia Severity
, Modality specific scores and percentile ranks for Auditory Comprehension, Lexical Retrieval,
Repetition, Alternative Communication
Scoring system on a scale from 0-3 on verbal subtests
Test-retest reliability including subtests: .64-.91
Strengths of ADP - ANS ✔✔-Extensive qualitative scoring for naming
-Reading/writing tested with a functional approach
-Collects behavioral profile, including emotional lability, impulsiveness
-Singing subtest to determine if Melodic Intonation Therapy (MIT) is appropriate
-Alternate communication subtest to determine if writing, gestures could be helpful for patient
Weaknesses of ADP - ANS ✔✔-Relatively limited sampling within subtests
-Limited linguistic information
-Not all patients classified
Boston Diagnostic Aphasia Exam (BDAE) - ANS ✔✔Localization oriented
Comprehensive sampling of language behaviors important in diagnosing classic aphasia
syndromes
3 formats- short, standard, extended
Has instructional video
Includes supplementary non-language tests
