(5) Assessment Flashcards
Chapter 5
Aphasia Assessment
Quantitative & qualitative data-gathering process of circumscribing an individual’s communicative function & activity limitations, understanding participation restriction, & devising appropriate rehabilitation objectives
Tools and Procedures
-Establish a diagnosis & prognosis
-Describing & understand all components of language functioning & related functions
-Gathering background information regarding individual with aphasia & family
-Seek input from the person with aphasia & family about assessment & rehabilitation goals
-Supporting initial communication interactions with the individual with aphasia
Assessment Administration
Procedures are divided into formal (administration of standardized tests) & informal (strategies employed by the clinician)
What type of test: encompasses many variables and usually yields quantitative results?
Formal assessments
Formal Assessment
Used as a synonym for a test
-Encompasses many variables
-Usually yields QUANTITATIVE results
Informal Assessment
Refers to the process of gathering information & observing patient’s behavior to make clinical decisions
-Usually yields QUALITATIVE results
Patient-related factor:
Where within the care continuum the individual with aphasia is receiving services
Purpose of formal assessment procedures
-establish the current level of communicative and cognitive functioning in the individual with aphasia
- identifying the presence, type and severity of aphasia
- delineating specific language and cognitive strengths and weaknesses
What does the ICF model construct?
-Loss of body function and structures
-Restrictions in activity participation
-Person factors
-Environmental factors
ICF Model
-ICF model constructs
Loss of body functions & structures
Restrictions in activity participation
Personal factors
environmental factors
-Assessment protocols should go beyond traditional focus & include additional formal & informal procedures to identify ACTIVITY & PARTICIPATION ISSUES and INFLUENTIAL ENVIRONMENTAL PERSONAL FACTORS
Standardization refers to
extensive sample of individuals who represent the population with whom the test will be used
Types of validity
- Content
- Construct
- Ecological
- Criterion related (predictive)
The process of administering a test to an extensive sample of individuals who represent the population segment on whom the test will be used
Standardization
Evidence-Based Practice
-Useful in guiding selection & administration of aphasia assessment procedures
-Clinicians should keep alongside advances in tests and procedures for QUANTIFYING and QUALIFYING aphasia & also critically evaluate these advances in terms of their VALIDITY & APPLICABILITY
Provides info pertaining to the degree with which a test yields similar data across repeated administrations under similar testing circumstances
Reliability
How would a clinician identify the most approapriate test for a client?
- consider the specific goals of the assessment
- review the psychometric characteristics of each test
Provides info on how well a test measures the skills or function that it contends to measure
Content validity
Boston Naming Test Spanish
developed to evaluate confrontation naming in Spanish Speakers, ensuring that culturally loaded items from the original BNT were excluded and items were reordered to reflect naming difficult in Spanish versus English
A type of criterion-related validity that indicates how well clients test scores reflect their behavior in their typical environments during their daily activities and interactions
Ecological validity
