- 99 Questions
This exam assesses advanced knowledge of assessment and evaluation of communication disorders, focusing on
evidence-based practice, standardized and non-standardized assessment tools, differential diagnosis, and
interpretation of results for intervention planning. Content aligns with current ASHA guidelines and LSVT LOUD
principles for Parkinson's disease. It contains 99 multiple-choice questions, each with four distractors and a fully
worked rationale that explains why the keyed answer is correct. Content is organized into 10 focused sections:
Assessment and Evaluation of Communication Disorders, Differential Diagnosis of Parkinson's Disease, LSVT
LOUD Treatment Principles and Techniques, Voice and Speech Characteristics in Parkinson's Disease,
Intervention Planning and Goal Setting, Patient and Caregiver Education, Outcome Measurement and
Documentation, Interprofessional Collaboration in Parkinson's Care, Ethical and Cultural Considerations in SLP
Practice, Evidence-Based Practice in Motor Speech Disorders. Targeted learning outcomes include: Select and
interpret appropriate assessment tools for communication disorders; Analyze assessment results to formulate
differential diagnoses; Apply psychometric principles to evaluate test reliability and validity; Integrate
patient-reported outcomes and clinical measures for comprehensive evaluation. Every item has been reviewed for
clinical accuracy, current guidelines, and clarity so that students can study with confidence and self-correct as
they work through the bank. Use it as a high-yield review immediately before the exam, or as a structured practice
Section 1: Assessment and Evaluation of Communication Disorders (Questions 1-10)
1 When selecting a standardized assessment for a patient with suspected
Parkinson's disease, which psychometric property is most critical for
ensuring the test can detect clinically meaningful change in vocal
intensity over a 4-week LSVT LOUD intervention period?
A) Test-retest reliability (r > 0.90)
B) Inter-rater reliability (kappa > 0.80)
C) Responsiveness (minimal clinically important difference established)
D) Concurrent validity (correlation with expert judgment > 0.70)
Answer: C
Rationale: Responsiveness refers to a test's ability to detect change over
time, which is essential for monitoring intervention effects. While
reliability and validity are important, without established MCID, the test
may not capture meaningful improvement. LSVT LOUD focuses on
increasing vocal intensity, so the measure must be sensitive to such
changes.
,2 A clinician is evaluating a patient with hypokinetic dysarthria. The
patient's sustained vowel phonation is 10 seconds, diadochokinetic rate
is 4 syllables/second, and reading passage shows 80% intelligibility.
Which combination of assessment tools would provide the most
comprehensive evaluation of the underlying pathophysiology and
functional impact?
A) Acoustic analysis of intensity and fundamental frequency,
auditory-perceptual rating (e.g., GRBAS), and a communication
participation questionnaire
B) Oral mechanism examination, spirometry, and a language
comprehension test
C) Videofluoroscopic swallow study, cognitive screening, and a voice
handicap index
D) Electroglottography, nasalance measures, and a motor speech
examination
Answer: A
Rationale: Hypokinetic dysarthria requires objective acoustic measures
(intensity, pitch) to quantify impairment, perceptual rating to describe
quality, and patient-reported outcomes to assess participation. Option B
includes unnecessary pulmonary and language tests. Option C focuses on
swallowing and cognition. Option D includes nasalance, which is less
relevant for hypokinetic dysarthria.
3 A patient with Parkinson's disease demonstrates a Voice Handicap Index
(VHI) score of 60 and a maximum phonation time of 8 seconds.
However, during conversational speech, the patient's vocal intensity
averages 55 dB SPL at 30 cm. Which discrepancy between assessment
results most directly informs the need for a specific treatment target?
A) The VHI score indicates high handicap, but MPT is within normal
limits; treatment should focus on respiratory support
B) The VHI score is high, but conversational intensity is adequate;
treatment should focus on patient perception rather than voice production
C) The MPT is reduced, yet conversational intensity is near normal;
treatment should target sustained phonation rather than loudness
,D) The VHI score is high, and MPT is reduced, but conversational
intensity is low; treatment should prioritize increasing vocal intensity in
connected speech
Answer: D
Rationale: The discrepancy between a high VHI (indicating perceived
handicap), reduced MPT (indicating respiratory-phonatory inefficiency),
and low conversational intensity (55 dB SPL is below typical 60-65 dB)
suggests the patient needs to increase loudness during functional
communication. LSVT LOUD targets high-effort, high-intensity
phonation to generalize to conversation.
4 When conducting a motor speech evaluation for a patient with suspected
hypokinetic dysarthria, which combination of tasks is most sensitive to
the core deficits of reduced amplitude and range of movement?
A) Sustained vowel phonation, alternating motion rates (AMRs), and
sequential motion rates (SMRs)
B) Conversational speech sample, oral reading, and diadochokinetic rates
C) Maximum phonation time, s/z ratio, and fundamental frequency range
D) Vowel prolongation, pitch glides, and loudness variation tasks
Answer: A
Rationale: Sustained phonation assesses respiratory-phonatory support
(amplitude), AMRs (e.g., /ptk/) test articulatory rate and precision, and
SMRs (e.g., /ptk/ in sequence) assess motor planning. These tasks directly
evaluate the reduced amplitude and range seen in hypokinesia.
Conversational tasks are less controlled. Pitch glides and loudness
variation are useful but not the most sensitive for core deficits.
5 A clinician is evaluating a patient with a progressive neurological
condition. The patient scores 85% on the Sentence Intelligibility Test
(SIT) and 70% on the Assessment of Intelligibility of Dysarthric Speech
(AIDS) in words. Which interpretation best explains the discrepancy?
A) The SIT overestimates intelligibility due to contextual cues, while
AIDS understimates due to single-word presentation
, B) The AIDS is more reliable because it uses a larger sample, so the SIT
score is likely inflated
C) The patient has greater difficulty at the sentence level than at the word
level, indicating a language disorder
D) The SIT is a measure of speech intelligibility, while AIDS measures
speech precision; the discrepancy is expected
Answer: A
Rationale: The SIT uses sentences, which provide contextual and syntactic
cues that can improve intelligibility, especially for listeners. AIDS at the
word level removes context, making it harder. The discrepancy does not
necessarily indicate a language disorder; it reflects the effect of context on
intelligibility. Both tests measure speech intelligibility, not precision.
6 Which of the following assessment approaches best captures the impact
of a communication disorder on an individual's participation in daily
life, as recommended by the WHO ICF framework?
A) Administration of the Communication Participation Item Bank
(CPIB)
B) Acoustic analysis of vocal intensity during a monologue
C) Perceptual rating of dysarthria severity using the Unified Parkinson's
Disease Rating Scale (UPDRS) speech item
D) Measurement of speech rate in syllables per second during reading
Answer: A
Rationale: The CPIB is a patient-reported outcome measure that directly
assesses perceived participation restrictions in communication situations.
Acoustic analysis and perceptual ratings address body functions, and
speech rate is an activity-level measure. The ICF emphasizes participation,
so tools like CPIB are essential for a holistic evaluation.
7 A patient with Parkinson's disease undergoes a comprehensive voice
assessment. Results show: jitter 3.5%, shimmer 8%, NHR 0.20, and
MPT 6 seconds. Which interpretation is most accurate regarding the
underlying pathophysiology?
