Formal and informal aphasia assessment across ICF domains Flashcards
What is the activity ICF domain for aphasia?
The 4 modalities: auditory comprehension, verbal expression, written comprehension, written expression
And tasks necessary for daily living
What is the participation domain for aphasia?
Functional tasks, eg. grocery shopping, playing a sport, getting a job
What are the goals of aphasia assessment? (5)
- Establish diagnosis/prognosis
- Describe and understand all components of language functioning
- Gathering background information (eg. literacy level, medial and social hx)
- Seeking input from PWA and family members re: rehab goals
- Establishing baseline and measuring outcomes
Considerations for assessment planning (3)
Must be planned case-by-case
- Current and prev level of functioning
- Current setting (acute/subacute/community)
- Client’s needs/goals/premorbid status
What do formal ax of aphasia? (5)
- Thorough understanding of pre-therapy performace
- May focus on impairment or activity/participation
- Differentiate linguistic skills, eg. lexical-semantic retrieval, syntax, reading/writing
- May be designed to classify aphasia syndrome
- Help to prioritise therapy goals
Pros of formal ax of aphasia (5)
- Language and cognitive skills examined in aphasia batteries support a range of functional behaviours.
- Assist in identifying the individuals retained abilities.
- Assist in determining: nature of problem, severity, resources that may be used in therapy and potential for recovery
- May be useful for less
experienced clinicians whose observations and hypothesis-testing skills may not be fully developed. - May highlight difficulties that had been overlooked or underestimated.
Cons of formal ax of aphasia (5)
- Potentially important aspects of language and communication are not adequately assessed
- Lengthy and timely
- Provide a measure of
language impairment rather than communication activities of daily living (e.g. conversation). - Time taken may be better used in observation of the individual person with aphasia and hypothesis driven administration of selective assessments (such as subtests of the PALPA)
- Do not provide a clear description of the underlying nature of the language disorder.
What are some examples of informal assessment of PWA? (3)
- Discourse samples: oral and written
Eg. pictural description, retelling a story, procedure - Assessment involving PWA and family members - functional focus!
Eg. Case history, communicative history - Dynamic assessment
Experimental approach, attempt to identify the effects of factors that may influence performance
How aphasia assessment can be made therapeutic (4)
- Aims to help a person understand the changes to their communication
- Assessment should be a learning process
- Identifies both strengths and weaknesses
- Explaining why the assessment is relevant to the person
Commonly used assessments in aphasia and related neurogenic communication disorders (4)
- Screening/bedside assessments (short, non-standardised)
- Comprehensive aphasia assessments
- Functional communication assessments
- QOL and self-esteem
What are some standardised aphasia test batteries? (4)
- Comprehensive Aphasia Test (CAT)
- Westerna Aphasia Battery (WAB)
- Boston Diagnosic Aphasia Examination (BDAE)
- Bilingual Aphasia Examination
What is the CAT?
- Purpose: Nature of language impairment and identify suitable aspects for treatment
- Part A: oral and written language comprehension
- Part B: expressive language inc. repetition, naming, picture desc, reading aloud, writing
- Also screens for neuropsychological difficulties
- Includes a disability questionnaire
What is the WAB?
Obtain ‘aphasia quotient’ AQ from 31 subtests considering:
- Spontaneous speech (content + fluency)
- Auditory comprehension
- Repetition
- Naming
- Reading
- Writing
Takes 1 hour +
What is the BDAE?
34 subtests
- Conversational and narrative speech
- Auditory comprehension
- Oral expression
- Reading
- Writing
Scores converted to percentiles and registered on subject summary profile
Takes 2-6 hrs
What are some standardised aphasia tests of specific language skills? (2)
- Boston Naming Test (BNT)
- PALPA
