Diagnostics Exam 1 Flashcards
What is assessment?
A. The process
8. SLP’s use of assessment
Why do we complete an evaluation?
A. To determine: Is there a disorder?
B. To compare with norms
C. To share with others
If there is a communication disorder, you will need to:
~ Describe the problem
~ Judge severity
~ Deal with the etiology
~ Prognostic statement
~ Make recommendations
~ Write goals/ objectives
For an assessment to have foundational integrity it needs to adhere to these 5 principles:
~ thorough
~ uses a variety of modalities
~ valid
~ reliable
~ tailored to the individual client
Typical Assessment Includes:
~ Case history
~ Interview
~ Evaluate oral-facial mechanism
~ Sample the client’s speech and language abilities
~ Screen hearing
~ Evaluate assessment information
~ Share findings
May need to make referrals to other professionals
True
Possible other referrals:
~ Psychologist/psychiatrist
~ OT, PT
~ Audiologist
~ Physician
~ Another SLP
Each assessment will differ slightly
True
Some have extensive case histories, clients have different communication difficulties, some cases involve extensive interviewing, some cases require detailed written reports.
Differences in Evaluation
What environment factors do you need to consider while doing a diagnostic?
~ Privacy/confidentiality
~ Room consideration
~ Recording consideration
~ Stimulus consideration
~ Time
~ Seating
~ Distance
~ Appearance
measurement of human traits, abilities, and certain processes
psychometrics
a test measures what it claims to measure
test validity
results are replicable
reliability
provides standard procedures for the administration and scoring of the test
standardization
a test measures predetermined theoretical construct, which is an explanation of a behavior or attribute based on empirical observation
construct validity
validity that is established by an external criterion
criterion validity
a tests validity in comparison to a widely accepted standard
concurrent validity
a tests ability to predict performance in another situation or at a later time
predictive validity
refers to a tests stability over time
test-retest reliability
refers to a tests internal consistency
split-half reliability
refers to the level of agreement among individuals rating the test
rater reliability
results are consistent when the same person rates the test on more than one occasion
intra-rater reliability
results are consistent when more than one person rates the test
inter-rater reliability
refers to a test’s correlation coefficient with a similar test determined by administering Test A and Test B to the same group of people and comparing the results to determine the test’s alternate form reliability
alternate form reliability
standardized tests = ______ tests
formal
_______________ provides standard procedures for the administration and scoring of the test
standardization
standardization helps to eliminate ___-_____ bias and other extraneous influences so they do not affect the client’s performance
test-giver
majority of standardizes tests are ____-__________, but not ALL standardized tests are ____-________
norm-referenced
any test may be standardized as long as uniform test administration and scoring are used
true
consecutive test items that must be correct prior to continuing testing
basal standardization
number of test items incorrect prior to discontinuing testing
ceiling standardization
exact age of child at the date tested
chronological age
adjustment made in age of child if born prematurely
adjusted age
the initial score obtained from test results, but must be converted to interpret test results
raw score
each test should include information about:
- the purpose of the test
- test construction and development
- administration and scoring procedures
- the normative sample group and statistical information derived from it
- test reliability
- test validity
most tests available to SLP’s are ____-________
norm-referenced
norm-referenced tests are often used for evaluating articulation and language disorders
true
norm referenced tests are always ____________
standardized
