EPPP Assessment and Diagnosis Principles 2 — Questions and Answers
Question 1: A psychologist administers an IQ test to a client and obtains a score of 95. The test has a standard error of measurement (SEM) of 5. What is the 68% confidence interval for the true score?
- 85-105
- 90-100 (Correct answer)
- 80-110
- 92-98
Correct answer: 90-100
The 68% confidence interval is calculated as the obtained score ± 1 SEM (95 ± 5 = 90-100).
Question 2: Which type of validity evidence is gathered by examining how well a test correlates with an established measure of the same construct administered simultaneously?
- Predictive validity
- Concurrent validity (Correct answer)
- Convergent validity
- Face validity
Correct answer: Concurrent validity
Concurrent validity is established by correlating a new test with an existing criterion measure administered at the same time.
Question 3: In the DSM-5, which specifier indicates that symptoms of a major depressive episode are present during the last two weeks of pregnancy or within four weeks after delivery?
- With anxious distress
- With melancholic features
- With peripartum onset (Correct answer)
- With atypical features
Correct answer: With peripartum onset
The 'with peripartum onset' specifier applies when depression onset occurs during pregnancy or within four weeks postpartum.
Question 4: A test yields consistent results across different occasions but does not measure what it claims to measure. This test has:
- High validity and low reliability
- High reliability and low validity (Correct answer)
- Low reliability and low validity
- High reliability and high validity
Correct answer: High reliability and low validity
Reliability is necessary but not sufficient for validity; a test can be consistently wrong (high reliability, low validity).
Question 5: Which neuropsychological test is most commonly used to assess visuospatial construction and executive planning abilities?
- Trail Making Test
- Rey-Osterrieth Complex Figure Test (Correct answer)
- Stroop Color-Word Test
- Wisconsin Card Sorting Test
Correct answer: Rey-Osterrieth Complex Figure Test
The Rey-Osterrieth Complex Figure Test assesses visuospatial ability and visual memory through copy and recall of a complex figure.
Question 6: A clinician suspects malingering on a neuropsychological evaluation. Which assessment tool is specifically designed to detect symptom validity and effort?
- MMPI-3
- Test of Memory Malingering (TOMM) (Correct answer)
- Structured Clinical Interview for DSM (SCID)
- Beck Depression Inventory
Correct answer: Test of Memory Malingering (TOMM)
The TOMM is a symptom validity test designed to detect feigned or exaggerated memory impairment.
Question 7: According to the DSM-5, the diagnosis of intellectual disability (intellectual developmental disorder) requires deficits in intellectual functioning AND deficits in:
- Language development
- Adaptive behavior (Correct answer)
- Social communication
- Academic achievement
Correct answer: Adaptive behavior
DSM-5 requires both deficits in intellectual functions and deficits in adaptive behavior across conceptual, social, and practical domains.
