Q

why use test battery and not single sensitive diagnostic test to diagnose CAPD

A

CAPD is not unitary disorder
- clinical presentations vary from number of mechanisms and auditory processes affected

  • different measures are required for accurate assessment of central auditory processes

Q

Test Battery Approach: questions asked to ensure diagnostic accuracy and usefulness

A

1) does the battery improve sensitivity and specificity over using individual tests
2) How many tests are needed to obtain optimal sensitivity and specificity
3) which combination if tests give the best sensitivity and specificity

Q

reason behind lax criterion trend

A

as size of test battery increases greater probability that a patient will fail any single test

  • normal patients have increased change of being incorrectly identified

9
Q

reason behind the strict criterion trend

A

as size of test battery increases, less probability that a patient will fail all tests

patient more likely to fail all tests when a battery has 2 to 3 tests compared to when it has 10 (more opportunities to pass)

Q

example of monaural low redundcy speech/auditory closure processes

A

Nu-6 filtered words
time compresses words
SSI-ICM
Speech in noise tests

23
Q

Dichotic processes test

A

different speech stimuli presented to each simultaneously (CVC or monosyllabic words, digits, or sentences)

24
Q

dichotic processes tests may assess either

divided attention:

Selective attention:

A

binaural integration or binaural separation

DA= repeat stimuli heard in both ears

SA = Ignore what is heard in one ear repeat what is heard in the target ear

25
dichotic process free call is used because and what it is
to prevent attention factors for contaminating results - repeating back words back without regard to which ear heard it
26
Dichotic tests are sensitive to lesions of
Corpus callosum and cerebral cortex
27
temporal processes and pattern tests
monotic presentation to assess each ear independently stimulus is often tones rather than speech
28
temporal processes and Patten tests temporal pattern test assess pattern perception and temporal functioning abilities including
feature detection abilities frequency/duration discrimination - acoustical pattern and contour recognition
29
temporal pattern tests are more sensitive to a compromised
right hemisphere if the test requires verbal response , it is sensitive to left hemisphere lesions
30
binaural interaction/fusion processes
test are binaural, stimuli presented to each ear at the same time assess integration between to ears
31
binaural interaction/fusion processes
unification of disparate information as a s single perceptual event takes place at the auditory brainstem
32
monaural low redundancy speech/auditory closure processes
- speech is redundant signal speech test involve modification (distortion) of acoustic signal to reduce amount of redundancy
33
monaural low redundancy speech/ auditory closure processes degraded speech stimuli are presented by modifying frequency, temporal, or intensity characteristic to reduce redundancy and are
sensitive to auditory closure abilities moderately sensitive to cortical lesions NOT BRAIN STEM LESIONS
34
What is CDA and what does it include
statistical measures that can be applied to individual and combinations of tests to determine maximum diagnostic value of tests - sensitivity and specificity - receiver operant curves - factor analysis (reduce large number of variables into fewer numbers of factors)
35
Recommended CAPD Evalution
- Case history - pre test standardized questionnaires - behavioral measures - electrophysiologic measures - psychoeducational evaluation - speech and language evaluation
36
case history components
Prenatal/postnatal developmental medical academic family social results of other evaluations work history
37
Screening tests Questionnaires 3 names
CHAPS (children's auditory performance scale) SIFTER (screening instrument for targeting educational risk) Fishers Auditory Problem Checklist
38
Screening tests typically have advantages over diagnostic tests
- more accesible less invasive/dangerous less time consuming less expensive less physically and psychologically uncomfortable for patients
39
CHAPS age range
7 years and older
40
CHAPS items
36 item checklist divided into six listening conditions and functions each item scores on a 7 point scale
41
CHAPS objective (3) and used by
parents and teachers - evaluates listening behaviors in diverse listening situations - assess child's ability in comparison to child's peers - used as part of screening process to identify children experiencing listening difficulties because of HL and CAPD
42
CHAPS SCORING - PASS - AT RISK RANGE
+36 to -11 -12 to -130
43
SIFTER Screening Instrument for targeting educational risk age range? completed by?
first through 5t grade teacher
44
Items of SIFTER (5)
15 questions three in each of five categorical areas 1) academics 2) Attention 3) communication 4) class participation 5) social behavior
45
Objective of SIfter
educationally screening students with known or suspected hearing loss classroom teacher compares childs functional ability to peers can be used to track childs performance over time
46
Fishers Auditory Problem Checklist
provides good information on children functional listening abilities in the classroom
47
Itemized behaviors in fishers auditory checklist
failure to attend to instructions need for repeated instructions easy distraction by auditory stimuli degrading processing in a competing acoustic environment also addresses attention and memory issues several questions related to language based deficits such as discrimination ability
48
fishers checklist contains? with value of how is it scored
25 items each with value of 4% each items not selected are multiplied by 4 for total percentage
49
fishers auditory problem checklist cut off score
72% at or below warrant a referral for further CAPD testing
50
what should be used to highlight concerns about a child but not determine wether a diagnostic capd assessment is warranted
CHAPS SIFTER TAPS-R
51
what tools from scan 3c screening test better predicted diagnosis of CAPD
Auditory figure ground Competing words free recall gap detection
52
electrophysiologic tests
oae immitance ABR (early latency response) Mid latency auditory evoked response late latency auditory evoked response
53
auditory evoked responses measures
neuromaturation and neuroplasticity of central auditory pathways
54
electrophysiologic tests provide additional information about
integrity of the CNS
