Chapter 4: Informed Consent Requirements

Description of Informed Consent Forms

General Requirements

The consent form gives potential research subjects sufficient written information to decide whether to participate in a research study. Legal informed consent requires that potential human subjects be given a full and fair explanation of the proposed research in order to understand the nature of their participation. The consent form documents and protects all parties: the subject, the investigator, and the institution. Therefore, it is important that consent forms present information in an organized and easily understood format. Research has concluded that consent forms written at approximately a sixth grade reading level facilitate comprehension by research subjects. We strongly suggest that investigators use the sample consent form or assent form when planning to conduct human subjects research. (Please see Chapter 12, "Form HS-2 or Form HS-3")

The form should be easily identified in bold text as "Consent to Participate in Research" at the top of the first page. Specific identifying information may also be included such as "Consent Form for Children" or "Consent Form for Controls" to ensure that the proper form is used to enroll potential subjects before initiating the research activity.

The title of the research should be descriptive and not unnecessarily scientific. The title submitted on a grant is often too technical and thus uninformative, therefore it is suggested that investigators create a lay title. Section headings should be used to clearly identify the required elements of informed consent.

The initial text of the consent form should include a statement identifying the names and degrees of all investigators, their department affiliation, and the basis for the selection of subjects. Inclusion criteria (e.g., a specific disease, condition, characteristic, background) should be explained as well as exclusion criteria (e.g., pregnancy, age limitations, health restrictions).

For example, a study regarding drug use may read: "You are asked to participate in a research study of drug use in Los Angeles because you are over eighteen years of age and are currently attending a drug rehabilitation program sponsored by the City of Los Angeles."

A study into a new AIDS therapy may read: "You are asked to participate in a research study testing the safety and effectiveness of a new AIDS drug because you are over eighteen years of age, have symptoms of AIDS, and are currently receiving no therapy for this disease."

The first paragraph of a consent form should clearly state that the investigator is presenting research and that as a result, the subject’s "participation in this research is entirely voluntary" [45 CFR 46.116(a)(1)] and the subject is free to discontinue or withdraw at any time.

Purpose of the Study

This section should provide a clear and accurate statement of the scientific purpose, the objectives of the research, the reasons why the study is being conducted, and a description of the background supporting the activity [45 CFR 46.116(a)(1)]. For instance, a "Purpose of the Study" section may read as follows for research with service programs for the homeless and the effectiveness of the services for the homeless community:

Many service programs are offered to homeless individuals who live without adequate food and shelter. However, many of these programs are not fully used by the homeless community. This research has been designed to determine whether homeless individuals actually require the services of these support programs and whether the programs are effectively informing the homeless community of available services.

Pilot Studies or Phase I Drug Studies:

Subjects making an informed decision regarding their willingness to undertake the risks of a project is a principal element of the informed consent process. The consent form should, therefore, indicate that the study is a "pilot" study or "Phase I" study and that the subject is one of the first to participate in the process, treatment, or intervention.

Procedures

This section should clearly identify the procedures that will be followed during the course of the research activity. The procedures should be presented to subject in the order of their occurrence and should detail the approximate duration for each activity the subject is expected to complete [45 CFR 46.116(a)(1)]. The following example may provide insight into how to write the "Procedures" section:

If you volunteer to participate in this research you will be asked to answer three sets of questions. The first set will include 25 questions about your living conditions. This section is expected to take about thirty (30) minutes to complete and will ask questions about how long you have been homeless, how often you eat, etc.

The second set of questions should take approximately one (1) hour to complete. There will be 40 questions about your knowledge of the support programs in your area. This section will ask you questions like, "Where would you go if you would like a hot dinner?" or "Where can you take a shower?"

A final set of questions should take approximately 30 minutes to answer. You will be asked twenty (20) questions about the services that would help you most.

There are situations where the difference between clinically indicated and experimental interventions must be explained for subjects in the "Procedures" section of the consent form. These sections should contain a clear statement regarding which procedures are experimental and which procedures are standard of care. Consider the following sample:

If you agree to participate in this research you will be asked to have a chest x-ray to make sure that you are healthy. The x-ray is performed on all patients with your condition whether or not they decide to participate in this research. Following the chest x-ray, you will be asked to provide ten (10) cc’s (approximately one tablespoon) of blood (usually from a vein in your arm). This blood draw will be performed for the purpose of this research only.

Potential Risks and Discomforts

The consent form is required to provide subjects with a clear understanding of any risks or discomforts which are reasonably anticipated during their participation in the research [45 CFR 46.116(a)(2)]. All foreseeable risks and/or discomforts of participating in a research should be addressed in the "Risks/Discomforts" section.

Risks should not be understated or overstated. In some cases it is appropriate to cite statistical probability of risk occurrence, risk prevention measures, reversibility and treatment. Appropriate disclosure of the potential risks associated with an intervention can be particularly difficult in clinical regimens where decisions are based upon available data. Investigators should consider the following example when addressing the risks/discomforts of participation in a research activity.

Because you will be asked questions about personal aspects of your life, you may feel embarrassed or uncomfortable while answering them. Also, because it may take up to two (2) hours for you to answer all the questions, you may become tired. You may stop answering questions and take a break at any time.

Anticipated Benefits to Subjects

This section of the consent form should state whether there are any direct benefits to the subject that may reasonably be expected as a result of participation in the research. Examples of direct benefit to the subject may include treatment of an illness, or knowledge of value to the subject (e.g., results of a cardiac stress test, results of an educational test, etc.). The potential benefits to the subject should not be overstated, coercive, or guaranteed. If there are no benefits to the subject it should be so stated [45 CFR 46.116(a)(3)].

Anticipated Benefits to Society

This section is suggested to ensure fair representation of potential benefits to prospective subjects. All research should have some underlying potential benefit to society (e.g., advancement of knowledge, health benefit to others, etc.).

NOTE: This section should not address payment issues as a benefit. Payment will be addressed later in the consent form. To continue the homeless survey example, benefits of the study might be described as follows:

You should not expect to benefit directly from this research. However, your participation in this research may lead to information that could help individuals who are homeless if it identifies better ways to support homeless people.

Alternatives to Participation

In clinical research, all consent forms are required to indicate any therapeutic alternatives available to the subject in the non-research and/or research context that may be of reasonable benefit to the subject. When appropriate, the relative risks/benefits of the therapeutic alternative vs. the research should be stated [45 CFR 46.116(a)(4)]. It is important to remember that an alternative could be supportive care or "watchful waiting" only.

Medical protocols which are not therapeutic in nature should state: "Since this protocol is not therapeutic in nature, the only alternative to participation is not to participate in this research." For studies involving alternative therapies, the research alternatives as well as other available treatments should be clearly distinguished and described. For example, a research study of a new schizophrenia medication may be described as follows:

You should be aware that you have alternatives to participation in this research activity. If you choose not to participate in this study, you may receive medications which are currently available, such as Clozapine and Risperidone. Your doctor can give you additional information about these therapies at any time.

In non-medical research the consent form should state any alternatives that may be advantageous to the subjects. For instance, if the subjects are students who will receive academic credit, the consent form should describe the alternatives available to earn equivalent academic credit.

Payment for Participation

Cash payments (if any) should be described in dollar amounts. Subjects should also be told how much of the payment they will receive if they do not complete the research. The HSPCs, in compliance with the stated position of the FDA, encourage adoption of a pro-rated payment system whenever possible.

The nature, amount and method of payment or other remuneration must not constitute undue inducement to participate (e.g., the payment alone should not serve as sufficient inducement for the subject to volunteer). Reimbursement may be provided for costs of participation (parking fees, travel, lost time from work, baby-sitters, etc.). Therefore, partial participation in a research activity would obligate partial payment. Also, any anticipated delays in processing payment (i.e., "it will take up to six weeks for you to receive your check") should be mentioned. A "Payment for Participation" section in a homelessness study might read as follows:

As a part of this study you will be asked to complete two 30-minute questionnaires, and one 1-hour questionnaire. You will be given $10 for each of the thirty minute questionnaires you complete and $20 for completion of the 1-hour questionnaire. If you complete the entire study, you will receive $40. If you decide to stop before completing all of the questionnaires, you will be given a portion of money based upon how much of the study you have completed.

If payment will be in the form of academic credit that will be awarded for research participation, the amount and type of credit should be clearly stated as well as any required conditions for credit.

Possible Commercial Products

The California State Supreme Court decided in the Moore vs. UC case that subjects have the right to know if material such as tumor tissue, bone marrow, blood, etc., will be turned into a commercial product. As a result, investigators are required to inform subjects in the consent form if any human materials (tumor tissue, bone marrow, blood, etc.) may be used to establish a commercially useful product (e.g., a cell line). Subjects should also be informed that they may not benefit from the development of the cell line. Standardized language is included in the Sample Consent Form for Medical Research (Please see Chapter 12, "Form HS-2").

Financial Obligation

This section of the consent form is required for medical, dental, psychological, research., etc., and should clearly state all financial obligations the subject may incur as a result of participation in the study (e.g., for physician fees, hospital charges, medication, pharmacy dispensary charges, laboratory tests, post-treatment follow-up, etc.). In addition, the section should also indicate if drugs, devices, tests or services will be provided free-of-charge. The consent form should disclose all potential additional costs to the subject as a consequence of procedures carried out for research purposes (e.g., extended hospitalization, additional tests, etc.). Potential subjects should be advised that most health benefit plans do not cover experimental treatments, and they must be told if their insurance companies will be billed.

Emergency Care and Compensation for Injury

A statement regarding "Emergency Care and Compensation for Injury" is a required element of the consent form for all research that presents more than minimal risk as determined by the HSPCs [45 CFR 46.116(a)(6)]. "Minimal Risk," as defined by the federal regulations, is "where the probability and magnitude of harm or discomfort anticipated in the proposed research are not greater, in and of themselves, than those ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests" [45 CFR 46.102(i)]. For example, the risk of drawing a small amount of blood from a healthy adult for research purposes is no greater than the risk of doing so as part of a routine physical examination. Investigators should explain in the consent form whether any compensation/medical treatments are available if injury occurs and, if so, describe the extent and nature of the compensation.

Standardized language currently approved by the University of California describes compensation for research-related injuries as follows:

If you are injured as a direct result of research procedures not done primarily for your own benefit, you will receive treatment at no cost. The University of California does not provide any other form of compensation for injury.

Privately Sponsored Drug and Device Trials

The University of California, Office of the President, issued a memorandum on February 3, 1995, entitled "Requirements for Administration of Agreements with Private Sponsors for Drug and Device Testing Using Human Subjects" (Please see Appendix 11, "February 3, 1995 memorandum form the Office of the President" for more information). Section II of the memorandum indicates that all contracts with private sponsors, "...must make explicit that the sponsor assumes responsibility for reimbursing the University for the reasonable cost of medical treatment for injuries directly resulting from participation in the study. It is not acceptable for such agreements to require billing of third party insurance companies in lieu of recovery of such costs from the sponsor, nor is it appropriate to accept provisions restricting participation of human subjects on the basis of medical insurance coverage status or on the subject’s ability to pay." Therefore, all consent forms requesting participation of human subjects in privately sponsored drug and device trials are required to indicate that:

If you are injured as a direct result of participation in the research, you will receive treatment at no cost. The University of California does not provide any other form of compensation for injury.

Privacy and Confidentiality

This section should state that any information obtained in connection with the research and that could identify the subject will remain confidential and will be disclosed only with the subject’s permission or as required by law. It should detail the extent to which confidentiality will be adhered to and how specific records identifying the subject will be maintained [45 CFR 46.116(a)(5)].

Suggested text for this section is as follows:

  • The only people who will know that you are a research subject are members of the research team and, if appropriate, your physicians and nurses. No information about you, or provided by you during the research, will be disclosed to others without your written permission, except:
    • if necessary to protect your rights or welfare (for example, if you are injured and need emergency care); or
    • if required by law

Limits to Confidentiality:

Depending on the subject matter of the research, there may be limits to the investigator’s promise of confidentiality to the subject. An example would be if a subject reveals information about possible child or elder abuse or if the investigator and/or the research staff discover the possibility of abuse. (Please see Chapter 7, Responsibilities of Principal Investigators: Confidentiality" and Chapter 10, "Special State of California Requirements: Reporting Suspected Abuse of Children, Elderly Individuals, and Others" for more information.) The HSPC recommends the following text for the consent form:

Under California law, the privilege of confidentiality does not extend to information about sexual or physical abuse of children or the elderly. If any member of the program staff has or is given such information, he or she is required to report it to authorities. The obligation to report includes alleged or probable abuse as well known abuse.

Confidentiality of Audio/Video-Tapes and Photographs:

Investigators are required to protect and/or disguise an individual subject’s identity when using photographs, videos, or audio-tape recordings. Statements regarding the use of photographs, videos, or audio-tape recordings should be consistent in both parental permission forms and children assent forms. For example, if the child’s assent form indicates that the photographs, videos, or audio-tape recordings are confidential and only the investigators will have access to the material, then the parental permission form should not indicate that the parent/guardian will have access to the tapes or photographs.

The investigator should clearly outline in the consent form whether the tapes will be used for classroom presentations, conventions, presentations, or possibly released to news or advertising media. The consent form should also indicate when the tapes/photographs will be destroyed. In addition, the consent form should indicate the provisions for masking the subjects’ identity. The HSPC recommends the following consent form statements for research that includes photographs, videos, or audio-tape recordings:

In the process of the research you will be videotaped (and/or photographed, and/or audio-taped). The tapes or photographs will be used for teaching and/or research purposes [indicate the types of purposes] only and your identity will not be disclosed. [The statement should also include an indication of when the tapes will be destroyed.]

If the subject is identifiable from the photographs, videos, or audio-tape recordings, the HSPC suggests the following statement:

You have the right to review the tapes/photographs made as a part of the study to determine whether they should be edited or erased in whole or in part.

Releasing Information:

If the investigator intends to release any information, the standard statement of confidentiality should be modified to state the person(s) or agency to whom information will be furnished, the nature of the information, the purpose of the disclosure and whether the subject’s name will be used. When the research records may be subject to inspection by the FDA, a funding agency, or an industrial sponsor, the following information must be included:

Authorized representatives of the Food and Drug Administration (FDA) [or a funding agency such as the National Institutes of Health] and the manufacturer of a drug [or device] being tested [insert name of company] may need to review records of individual subjects. As a result, they may see your name, but they are bound by rules of confidentiality not to reveal your identity to others.

When the results of the research are to be published or presented at conferences, it is the investigator’s responsibility to make sure that no personal information will be included that would reveal a subject’s identity.

Participation and Withdrawal

Federal regulations require a clear statement in all consent forms that participation in the study is voluntary, refusal to participate will involve no penalty or loss of benefits to which the subject is otherwise entitled, and the subjects may discontinue participation at any time without penalty of loss of benefits to which the subject is otherwise entitled [45 CFR 46.116(a)(8)].

The Participation and Withdrawal section of a medical consent form is required to contain the following notice:

Your participation in this research is VOLUNTARY. If you choose not to participate, that will not affect your relationship with UCLA (or UCLA Medical Center), or your right to health care or other services to which you are otherwise entitled. If you decide to participate, you are free to withdraw your consent and discontinue participation at any time without prejudice to your future care at UCLA.

The Participation and Withdrawal section of a non-medical consent form is required to contain the following notice:

Your participation is VOLUNTARY. If you decide to participate, you are free to withdraw your consent and discontinue participation at any time without penalty. Your decision whether or not to participate will not affect your relationship with [name agency, health care provider, school, etc. where subject was recruited].

Consequences of Withdrawal

When appropriate, the consent form should state the consequences (e.g., medical/health) of a subject’s decision to withdraw from the research. If applicable, the consent form should also state any anticipated circumstances (e.g., adverse reactions, non-adherence to protocol instructions) under which the subject’s participation may be terminated by the investigator or sponsor without regard to the subject’s wishes.

The investigator may withdraw you from this research activity (without your consent) if certain circumstances arise. For example, you may be withdrawn from this study if the investigator feels that your continued participation places you at unnecessary risk of harm or you become ineligible (because of illness) to continue. [If appropriate, describe the anticipated circumstances under which the subject’s participation may be terminated by the investigator without regard to the subject’s consent.]

The section (if applicable) should address the following: In some cases withdrawal from a study may involve some consequences for the subjects that they should be made aware of prior to enrolling into a study. For example, during the course of a vaccine trial, a subject may be challenged with an infectious agent. If the subject decides to end participation in this type of activity after the challenge, there may be a period of time where the individual may be forced to continue quarantine prior to discharge from the study discharge. Sample language follows:

Although you may decide to withdraw from this research at any time, you are enrolling into a trial where you will be given a bacteria that causes disease in unvaccinated individuals to see if the vaccine protects you from becoming sick. After the injection, the study team must ensure that you cannot infect others with the bacteria. You will therefore be required to stay for three days and receive antibiotic therapy. You will be allowed to leave the study after that three day period.

New Findings

In medical, dental, psychological research, etc., the federal regulations require the inclusion of a separate statement indicating that if new information, such as changes in the risk/benefit ratio, or new alternatives to participation develop during the course of the study that may affect a subject’s willingness to continue participating, the subject will be informed promptly and may then decide whether to continue participating in the ongoing study. The HSPC will advise the PI whether or not subjects should be asked to sign a revised consent form.

Identification of Investigators

All consent forms must include a section explaining who can be contacted for answers to questions about the research, such as the results, and whom to contact in the event of a research related injury [45 CFR 46.116(a)(7)]. The "Identification of Investigators" section should clearly identify the members of the study team who may be contacted and a contact telephone number that can be used (24 hours a day, 7 days a week for greater than minimal risk studies). For more than minimal risks research the "Identification of Investigators" section of the consent form may be provided to subjects by the following statement:

In the event of a research related injury or emergency, or if you experience an adverse reaction, please immediately contact one of the investigators listed below. If you have any questions about the research, please feel free to contact the following individuals at their listed numbers (24) hours a day, (7) days a week.

Rights of Research Subjects

For research determined by the HSPCs to be more than minimal risk the investigator is required to make a statement regarding the rights of research subjects. (Please see Chapter 5, "Risk/Benefit Assessment" for information regarding risk.) This section of the Consent Form may not be modified by investigators. It must read as follows:

You may withdraw your consent at any time or discontinue your participation without penalty. By signing this consent form you are not waiving any legal claims, rights or remedies because of your participation in this research study. If you have any questions regarding your rights as a research subject, you may contact the Office for the Protection of Research Subjects, University of California Los Angeles, Box 951694, Los Angeles, CA 90095-1694; telephone: (310) 825-8714.

Additional Elements

Additional elements of informed consent may apply to certain research activities. Current federal regulations can be found at [45 CFR 46.116(b)(1-6)]. The following items should be addressed if they apply, and investigators should feel free to select simple titles for these sections:

  • When appropriate, a statement that a particular treatment or procedure may involve risks to the subject (or to the embryo or fetus, if the subject is or may become pregnant or if the male can induce harm to an embryo or fetus through contact with pregnant female) which are currently unforeseeable [45 CFR 46.116(b)(1)].
  • When appropriate, the approximate number of subjects involved in the study should be detailed in the consent form [45 CFR 46.116(b)(6)].
  • When appropriate, subjects should be told who is funding the research (drug company, device manufacturer, CIA).
