Types of consent
Back to Contents
Human subjects asked to contribute their time and effort to research should consent to do so freely. The consent should be given only after the subject understands what he or she is consenting to, and any risks that may be involved. Subjects should be assured that there will be no penalties for declining to participate, and that they are free to withdraw from the research at any time after they have given their initial consent. Federal regulations state this more formally:
"An investigator shall seek such consent only under circumstances that provide the prospective subject or the representative sufficient opportunity to consider whether or not to participate and that minimize the possibility of coercion or undue influence. The information that is given to the subject or the representative shall be in language understandable to the subject or the representative. No informed consent, whether oral or written, may include any exculpatory language through which the subject or the representative is made to waive or appear to waive any of the subject's legal rights, or releases or appears to release the investigator, the sponsor, the institution or its agents from liability for negligence."
The requirement for informed consent is ordinarily fulfilled by telling the subject, either orally or in writing,
Human Subjects Review Committees will consider the adequacy of the provision for such informed consent and whether the information given is in compliance with relevant requirements in Federal regulations.
When research involves certain special features or certain special populations, consent requirements specific to those features or populations apply. These requirements are detailed elsewhere in this section.
Federal regulations require that, in most cases, whenever there is more than minimal risk, consent is to be documented by a signed and dated consent form that has been approved by a Human Subjects Review Committee. A copy must be provided to the participant or the participant's legal representative. There are some exceptions to this requirement that are described below (see following sections on Oral Consent, Proxy Consent and Waiver of Consent.
Informed consent, including a signed and dated consent form, may also be appropriate for research exempt from Federal Regulations. Department chairs are authorized to require appropriate documentation of informed consent when approving exempt research.
Investigators are advised to read this section carefully. Many of the delays in proposal approval have been due to inadequate attention to including all necessary information in the consent form.
Revised Code of Washington 42.48, enacted in 1985, provides protection of research data from subpoena under certain circumstances. This law pertains specifically to data collected in the State of Washington.
The law provides protection for research data from subpoena of records for the purpose of taking any legal action against an individual subject. RCW 42.48 does not restrict access to individually identifiable research records if:
Investigators collecting data on illegal and sensitive data may wish to request a Federal Certificate of Confidentiality from the DHHS. Investigators who have been issued such a Certificate cannot be compelled to identify research subjects in any Federal, state, or local civil, criminal, administrative, or legislative proceedings. Further information on such Certificates may be obtained from the Human Subjects Division.
As appropriate, the following should be included in the informed consent statement:
An estimate of the hazard in terms readily understandable to the layman, e.g., a multiple of the background radiation to which people are exposed in one year, or as comparable to the exposure allowed radiation workers in one year. (For further information about radiation research, see Section VII.B.)
Any special risks that may be associated with the equipment, and a description of what equipment will be used and how it will be used in the research.
A statement that participation in the research project will have no effect on the inmate-participant's release date or parole eligibility.
Written consent is usually appropriate for research involving more than minimal risk. The written consent form normally consists of an information statement from the point of view of the investigator, written in language readily understandable to potential subjects, plus a statement of consent for the subject to sign. For potential subjects who are not English-speakers, the consent form should, of course, be presented in their own language. For special populations (e.g., children, legally incompetent persons), the consent of a legally responsible guardian or subject advocate may also be required. In addition to the written statement, potential subjects must have an opportunity to discuss with the investigator or the investigator's representative their concerns about participation and any questions they may have.
Subjects' consent is documented by their dated signature on the consent form and, when appropriate, by the dated signature of their legally authorized representatives, guardians or subject advocates. The investigator retains one copy of the signed consent form and gives one copy to the subject. Signed consent forms are to be retained by the investigator for a period of eight years.
The Human Subjects Review Committees may waive documentation of written consent in several situations. One is when the study poses minimal risks to the competent adult subject and the study procedures are not ones that would normally require written consent. The second is when the major risk posed to the subject is the existence of a signed consent document. When research is conducted on illegal or very sensitive behavior, subjects may be putting themselves at risk of criminal or civil liability or personal danger by signing a consent form. For example, subjects of research on cocaine dealing or domestic abuse would be ill advised to sign a consent form indicating that they were willing to take part in such studies.
A sample consent form format is included at the end of this manual. Investigators are strongly advised to draft consent forms to comply with the relevant requirements, in the order just listed, to avoid delays in approval.
Investigators are advised not to duplicate large numbers of their informed consent forms prior to approval, since changes may be required. Investigators are also urged to pay special attention to the form, appropriateness, and clarity of their consent forms. Consent forms should be written in short sentences using short words. Use the active rather than the passive voice and avoid jargon and technical language.
Oral rather than written consent may be obtained for research involving no more than minimal risk. Oral consent may also be appropriate under certain other circumstances and with IRB approval. For example, research in which identification by the consent document itself would place the subject at risk ordinarily makes oral consent preferable to written consent. (See Title 45, Code of Federal Regulations, Part 46.117(c).) Also, oral consent may be approved for interviews conducted by telephone under certain circumstances. (See Title 45, Code of Federal Regulations, Part 46.117(c).)
Investigators who request approval of oral consent for research involving more than minimal risk should provide a justification for the use of oral consent and a copy of the information statement to be presented or read to potential subjects. At a minimum, this statement should include the relevant elements of informed consent described in Section IV.C.
All uses of proxy consents must be approved prospectively by a Human Subjects Review Committee. There are several instances in which proxy consent may be approved. It may be approved in situations in which the prospective subject is anticipated to be incompetent to provide informed consent. This may be temporary (for example, when subjects have received sedating or pain-relieving medications and consent must be obtained before the effects of the medication have worn off). The duration of the incompetence may be unknown (for example, when a potential subject is in a coma resulting from traumatic injury). Or the incompetence may be a normal state (for example, when a subject is permanently cognitively impaired). The subject's legally authorized representative is responsible for making the decision about whether or not the subject should participate in the research. This person signs the consent form for the subject and indicates his or her relationship to the subject on the form.
Consent from the subject's legally authorized representative should be obtained by the researcher in person and documented on the approved consent form. If this is not possible, the consent form may be sent to the representative by facsimile transmission, express mail or regular mail and returned using the same mechanisms. In circumstances in which the Human Subjects Review Committee has approved a waiver of the documentation of informed consent (see below, Waiver of consent; consent may be provided by the representative over the telephone. When obtaining consent by telephone, the researchers must follow these procedures:
Consent provided by a proxy (whether by telephone, in writing, or in person, cannot override refusal by the prospective subject to take part in the research.
Under certain conditions described in the Federal Regulations,
a Human Subjects Review Committee may approve a consent procedure
which does not include, or which alters, some prescribed elements of
informed consent, or a Committee may waive the requirement that
informed consent be obtained. The essential conditions to allow a
waiver are
Under special circumstances, consent may also be waived for the use of an FDA-regulated test article (drug, device, or biologic). In this case, the investigator shall consult with the Human Subjects Division and a Human Subjects Review Committee Chair. In order to waive consent both the investigator and a physician who is not otherwise participating in the clinical investigation certify in writing all of the following:
The requirement for a written, signed consent form may be waived by a Human Subjects Review Committee if
Waiving the requirement for a written form does not waive the requirement that subjects be informed of the nature of the research, and that their consent (or the consent of their legal representatives) be obtained whenever appropriate.
Sometimes investigators wish to use what they call "passive" consent -- absence of a dissent to participate is assumed to imply willingness to take part in a study. "Passive" consent qualifies as a waiver of consent and a request to use "passive" consent must meet all the requirements of a waiver of consent.
The Committees may grant waivers of consent in compliance with regulations from the FDA and the NIH in certain emergency medicine research activities meeting the regulatory requirements. The Committee must find and document that:
Researchers requesting a waiver of informed consent for studies involving an investigational drug or device must obtain a unique investigational new drug application (IND) or investigational drug exemption (IDE) from the FDA even if an IND or IDE for the intervention already exists.
If the Human Subjects Review Committee declines to approve a requested waiver, it must document its findings and report promptly to the researcher and to the sponsor of the research. The research sponsor, in turn, must report this information to FDA and to the sponsor's researchers who are asked to participate in this or a substantially similar trial.
This rule does not apply to protocols involving populations and procedures which are specially protected by law. These include prisoners, fetuses, pregnant women, or in-vitro fertilization procedures.
Assent is required of all minors who are approached to take part in a research activity. Assent should be appropriate to the age of the child.
Children over the age of twelve may be asked to read, discuss and sign an adult consent form. If the consent form is being used for both adolescent and adult subjects, it should be titled "Assent/Consent Form" and signature, date, and relationship lines should be added to the form. Both the adolescent and the parent or guardian should sign the form.
Children who are between the ages of seven and twelve should be provided with a simplified version of the adolescent assent form written in language appropriate to the ages of the subject. Both the child and the parent or guardian must sign the form.
Oral assent may be used with children who cannot be expected to read, but who can be expected to comprehend the nature of the research procedures to be used.
Children who cannot understand enough to assent to participate in research activities generally cannot be research subjects. The only exception is if the research holds out a prospect of direct benefit to the child which is available only in the context of the research, and if consent is provided by one or both parents, or if the research poses minimal risks to the child which are outweighed by the prospective benefits. It is the responsibility of the Human Subjects Review Committee to make this determination on a case-by-case or protocol-wide basis.
Generally speaking, if minors are the subjects of research, the informed consent of the parent(s) or legal guardian is also required. An exception is made for individuals who have been declared "emancipated" minors and for children in the state of Washington aged fourteen years old and older who are seeking diagnosis or treatment for sexually transmitted diseases. Investigators should direct questions to the Human Subjects Division for information on this subject.
When data are gathered by anonymous questionnaires (i.e., there is no possibility of identifying subjects), the return of the completed questionnaire implies the consent of the subject. No written informed consent form for the subject's signature is required. However, such questionnaires should be accompanied by a cover letter that provides all of the applicable elements of consent
