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

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
Q

dichotic process

free call is used because and what it is

A

to prevent attention factors for contaminating results

  • repeating back words back without regard to which ear heard it
26
Q

Dichotic tests are sensitive to lesions of

A

Corpus callosum and cerebral cortex

27
Q

temporal processes and pattern tests

A

monotic presentation to assess each ear independently

stimulus is often tones rather than speech

28
Q

temporal processes and Patten tests

temporal pattern test assess pattern perception and temporal functioning abilities including

A

feature detection abilities
frequency/duration discrimination

  • acoustical pattern and contour recognition
29
Q

temporal pattern tests are more sensitive to a compromised

A

right hemisphere
if the test requires verbal response , it is sensitive to left hemisphere lesions

30
Q

binaural interaction/fusion processes

A

test are binaural, stimuli presented to each ear at the same time

assess integration between to ears

31
Q

binaural interaction/fusion processes

A

unification of disparate information as a s single perceptual event takes place at the auditory brainstem

32
Q

monaural low redundancy speech/auditory closure processes

A
  • speech is redundant signal
    speech test involve modification (distortion) of acoustic signal to reduce amount of redundancy
33
Q

monaural low redundancy speech/ auditory closure processes

degraded speech stimuli are presented by modifying frequency, temporal, or intensity characteristic to reduce redundancy and are

A

sensitive to auditory closure abilities

moderately sensitive to cortical lesions

NOT BRAIN STEM LESIONS

34
Q

What is CDA and what does it include

A

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
Q

Recommended CAPD Evalution

A
  • Case history
  • pre test standardized questionnaires
  • behavioral measures
  • electrophysiologic measures
  • psychoeducational evaluation
  • speech and language evaluation
36
Q

case history components

A

Prenatal/postnatal
developmental
medical
academic
family
social
results of other evaluations
work history

42
Q

CHAPS SCORING
- PASS
- AT RISK RANGE

A

+36 to -11
-12 to -130

43
Q

SIFTER

age range?
completed by?

A

first through 5t grade
teacher

44
Q

Items of SIFTER

(5)

A

15 questions three in each of five categorical areas

1) academics
2) Attention
3) communication
4) class participation
5) social behavior

45
Q

Objective of SIfter

A

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
Q

Fishers Auditory Problem Checklist

A

provides good information on children functional listening abilities in the classroom

47
Q

Itemized behaviors in fishers auditory checklist

A

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
Q

fishers checklist contains? with value of

how is it scored

A

25 items each with value of 4% each

items not selected are multiplied by 4 for total percentage

49
Q

fishers auditory problem checklist cut off score

A

72% at or below warrant a referral for further CAPD testing

50
Q

what should be used to highlight concerns about a child but not determine wether a diagnostic capd assessment is warranted

A

CHAPS
SIFTER
TAPS-R

51
Q

what tools from scan 3c screening test better predicted diagnosis of CAPD

A

Auditory figure ground
Competing words free recall
gap detection

52
Q

electrophysiologic tests

A

oae
immitance
ABR (early latency response)
Mid latency auditory evoked response

late latency auditory evoked response

53
Q

auditory evoked responses measures

A

neuromaturation and neuroplasticity of central auditory pathways

54
Q

electrophysiologic tests provide additional information about

A

integrity of the CNS
