HSR Vulnerable Populations Protection 1 — Questions and Answers
Question 1: Under 45 CFR 46, which Subpart provides additional protections specifically for children involved in research?
- Subpart A
- Subpart B
- Subpart C
- Subpart D (Correct answer)
Correct answer: Subpart D
Subpart D of 45 CFR 46 contains additional protections for children as research subjects, requiring parental permission and child assent.
Question 2: When a child is capable of understanding a research study, the researcher must obtain:
- Only parental consent
- Assent from the child and parental permission (Correct answer)
- Only the IRB's approval
- A waiver signed by the child's guardian
Correct answer: Assent from the child and parental permission
Federal regulations require both parental permission and the child's affirmative assent when the child is capable of providing it.
Question 3: Which ethical principle from the Belmont Report is most directly invoked when ensuring vulnerable populations are not exploited in research?
- Respect for Persons
- Beneficence
- Justice (Correct answer)
- Autonomy
Correct answer: Justice
Justice requires that the benefits and burdens of research be distributed fairly and that vulnerable groups are not disproportionately enrolled to serve others' interests.
Question 4: Pregnant women are classified as a vulnerable population in human subjects research primarily because:
- They cannot legally provide informed consent
- Research risks may extend to the developing fetus (Correct answer)
- Federal law prohibits their enrollment in any study
- They are always considered economically disadvantaged
Correct answer: Research risks may extend to the developing fetus
Pregnant women require additional protections because interventions or exposures can affect not only the woman but also the fetus.
Question 5: A legally authorized representative (LAR) is most commonly required in research when a participant:
- Is under 18 years old
- Lacks decision-making capacity (Correct answer)
- Is incarcerated in a federal facility
- Belongs to an economically disadvantaged group
Correct answer: Lacks decision-making capacity
An LAR is needed when an adult lacks the cognitive or legal capacity to provide meaningful informed consent on their own behalf.
Question 6: Under 45 CFR 46 Subpart C, which category of research involving prisoners is explicitly permissible?
- Research on any condition affecting the general public
- Research on the possible causes of criminal behavior without limits
- Research on conditions particularly affecting prisoners as a class (Correct answer)
- Research solely designed to benefit non-prisoner populations
Correct answer: Research on conditions particularly affecting prisoners as a class
Subpart C permits research on conditions such as vaccine trials for hepatitis because hepatitis disproportionately affects prisoners as a class.
Question 7: When may an IRB waive the requirement for parental permission for a minor's participation in research?
- When the study involves greater than minimal risk
- When parental permission is not a reasonable requirement to protect the subjects (Correct answer)
- When the child is at least 10 years old
- When fewer than 20 minors are enrolled
Correct answer: When parental permission is not a reasonable requirement to protect the subjects
An IRB may waive parental permission when requiring it would not reasonably protect the child, such as in research on abused or neglected children.
