Seminar Outline:Vulnerable Populations� Introduction and relevant terms

� Vulnerable populations� People with mental disorders or decisional impairments� People who are economically disadvantaged� People who are educationally disadvantaged

� Q&AStatutorily Protected; Non-Statutorily Protected; *45 CFR 46

People with Mental Disorders or Decisional Impairments� Statutorily protected

� Mental disorder vs. decisional impairment


People with Mental Disorders or Decisional Impairments (cont’d)

Mental disorder is� a clinically significant psychological syndrome that occurs in

an individual and is associated with distress, disability, or with an increased risk of suffering death, pain, or an important loss of freedom;


important loss of freedom;� must not be an expected and culturally sanctioned

response to a particular event.

American Psychiatric Association (2000)


Decisional impairment� The ability to reason and make sound choices is affected. � Not a chronic condition; it might be temporary, permanent,

progressive, or fluctuating.


Delano (2006)


Lacking the ability to provide valid informed consent.� Parent, legal guardian, legally authorized representative (LAR)

Ethical concerns: Respect, Justice, Beneficence.


Protections should be broadly applied regardless of particulars� A person impaired by brain injury or diabetes.� A person impaired as a result of schizophrenia or depression.� Both are entitled to the same level of protection.

Delano (2006)

People with Mental Disorders or Decisional Impairments (cont’d)� IRB regularly reviews research involving adults with

decisional impairments � membership includes persons familiar with the nature of impairment.

� Does not regularly review this type of research �� Scientific/clinical expertise� Patient/consumer representative


� Patient/consumer representative� Family member (spouse, parent, LAR)� Advocacy group member

� As complexity and risks of procedures increase, the required level of capacity should also increase.

Delano (2006)

People Who are Economically Disadvantaged� Statutorily protected� Economic vulnerability refers to the lack of “access to

adequate income, housing, or health care”.� A Principal Investigator (PI) may not recruit an individual who

is economically vulnerable when research participation “appears to offer benefits that are badly needed and only


“appears to offer benefits that are badly needed and only available to the individual through research participation”.

� Ethical concerns: Respect, Justice

DuBois (2006)

People Who are Educationally Disadvantaged� Statutorily protected� Educational vulnerability refers to having

� “limited education,”� not being able to read or write, or� “may do so at a lower level than the general population of a


� “may do so at a lower level than the general population of a given community”.

� The PI could use other materials (e.g., pictures, videos) that would help potential participants with educational vulnerability understand all information necessary for informed consent.

� Ethical concerns: Respect, Justice

Students and Employees� Non-statutorily protected

DuBois (2006)The Ohio State University HRPP Policies & Procedures (2009)

Students� Students should not be recruited by their professors when

those professors are the PIs.� Students may be recruited through student participant

pools� E.g., Psyc 202 participant pool


� E.g., Psyc 202 participant pool� Such recruitment may be facilitated by the students’

professors, provided that those professors are not the PIs.

Employees� Non-statutorily protected

who are higher in rank.� Employees may be recruited by researchers other than

their direct or indirect employer, supervisor, or other members within the same department.

The Ohio State University HRPP Policies & Procedures (2009)

Case Study� A professor asked her students to do her a favor by staying

after class for a few minutes to fill out a research questionnaire. She added that this task was voluntary, but when a student, Andy, began to leave, the professor said, “I’m certainly glad that the rest of you are willing to help me out.” Andy sat down, but was embarrassed and felt he had


Andy sat down, but was embarrassed and felt he had jeopardized his standing with the professor.

out the prospect of direct benefit to the childIf it presents more than minimal risk and


� If it presents more than minimal risk and holds out no direct benefit to the child, it promises to generate important scientific knowledge about conditions that affect the wellbeing of children

*Definition of minimal risk is presented on next slide

Consent

� Consent for participation should be provided on behalf of the child by a parent (biological or adoptive) or a legal guardian

� Consent from both parents is required in the case research poses more than minimal risk,


case research poses more than minimal risk, unless one parent is not available*

� Parental consent can be waived in the case of neglected or abused children, provided a mechanism is in place to ensure protections to this group of children in research

*Deceased, unknown, incompetent

Assent

� In addition to consent, assent – a child’s agreement to participate in research – should be solicited and documented when appropriate*

inducement, monetary or otherwise, to terminate the pregnancy
