,Q1. A psychologist is subpoenaed to release therapy records in a child custody case.
The psychologist believes release would harm the child. Under HIPAA and APA
ethics, what is the most appropriate initial action?
A. Release the records because a subpoena is a court order.
B. Withhold the records entirely and assert psychotherapist-patient privilege.
C. Seek legal counsel and, if possible, obtain a protective order or quash the subpoena.
D. Release only the diagnostic summary, not process notes, to minimize harm.
Correct Answer: C. Seek legal counsel and, if possible, obtain a protective order or
quash the subpoena.
Rationale: A subpoena is not a court order; psychologists must seek legal advice and
attempt to protect confidentiality via a protective order or motion to quash before
releasing records. Releasing fully or partially without legal process violates
confidentiality and ethical duties.
Why Wrong:
A - A subpoena alone does not compel disclosure; it is a request, not a court order.
B - Absolute refusal may be legally inappropriate if a valid court order exists; the
psychologist must engage legal process.
D - Partial release without legal direction still breaches confidentiality and may not
satisfy legal requirements.

Psychologists and Code of Conduct, Standard 4.05; HIPAA Privacy Rule 45
CFR 164.512(e).
Q2. A test manual reports a reliability coefficient of 0.90 for a new anxiety scale. A
clinician uses it to make high-stakes treatment decisions. Which psychometric
limitation is most critical?
A. The coefficient is too low for any clinical use.
B. Reliability is sample-specific; the clinician must evaluate the SEM and confidence
intervals for the intended population.
C. A reliability of 0.90 indicates the test is valid.
D. The test likely has poor content validity because reliability is high.
Correct Answer: B. Reliability is sample-specific; the clinician must evaluate the SEM
and confidence intervals for the intended population.
Rationale: Reliability coefficients are not fixed properties; they vary across samples and
settings. Clinicians must consider the standard error of measurement (SEM) and
confidence intervals to interpret scores accurately for their specific population. High
reliability does not guarantee validity.
Why Wrong:
A - 0.90 is generally high, but the critical issue is applicability to the specific
Page 3
, population, not the absolute value.
C - Reliability is necessary but not sufficient for validity; this is a common
misconception.
D - High reliability does not imply poor content validity; they are independent
concepts.

Association, & National Council on Measurement in Education. (2014).

Q3. In a randomized controlled trial, 40% of participants in the treatment group
drop out before post-test, and they have higher baseline severity than completers.
Which statistical conclusion is most threatened?
A. Internal validity, specifically due to attrition bias.
B. External validity, because dropouts are more severe.
C. Construct validity, due to inadequate outcome measures.
D. Statistical conclusion validity, due to low power only.
Correct Answer: A. Internal validity, specifically due to attrition bias.
Rationale: Differential attrition (more severe participants leaving) creates systematic
bias, threatening internal validity by making groups non-equivalent. This is a classic
threat to causal inference. External validity is also affected but the primary threat is
internal.
Why Wrong:
B - External validity is a secondary concern; the immediate threat is to causal
inference.
C - Construct validity concerns the measures, not participant attrition.
D - Low power is a separate issue; attrition creates bias, not just reduced power.

Quasi-Experimental Designs, Ch. 3.
Q4. A psychologist is asked to provide an opinion on an individual's competence to
stand trial. Which forensic assessment principle is most essential?
A. Use a fixed battery of neuropsychological tests to ensure objectivity.
B. Base the opinion solely on clinical interviews to avoid test bias.
C. Use assessment instruments validated for the specific legal standard and consider
response validity.
D. Provide a diagnosis of mental disorder to establish incompetence.
Correct Answer: C. Use assessment instruments validated for the specific legal
standard and consider response validity.
