Informed Consent Process


The Consent Process

See the Protocol Forms, Sample Templates, and Appendices page for sample informed consent, assent, and permission templates.

The foundation for human subjects research is that individuals participate voluntarily. Informed consent means that the research population fully understands the purpose, risks, and benefits of the research study before agreeing to participate. Thus, information about a study must be expressed in language appropriate for the study population. But because participants always retain the right to withdraw from a study, informed consent is an ongoing process that continues until a subject’s participation is complete.

Written consent forms are required for most research, except in the following cases:

  1. With mailed, e-mailed, or web-based surveys, the participant's decision to return the survey or complete the online survey may represent his/her consent. However, an introductory statement must be included at the beginning that describes the nature of the study (as on a standard consent form) and explains that by submitting the questionnaire/survey, the participant is providing his/her consent.
  2. When obtaining signed consent is not feasible or may increase risk to participants, the researcher must first explain the nature of the study (as on a standard consent form), and then a subject may give oral consent. If audio or video data is to be collected, the oral consent should be recorded.  (Examples: interviews with indigenous people who do not have a written language, or interviews with people who state that they do not wish to sign their names to preserve anonymity.)
  3. For minimal risk studies that do not collect direct identifiers or enough indirect identifiers (such as demographics) to determine an individual's identity, researchers may request to use an "information sheet" that they distribute to potential participants, who read and retain the sheet. Then, the researcher may obtain oral consent, and the individuals' decision to participate represents his/her ongoing consent.

Federal Requirements for the Consent Form

In accordance with Federal regulations [45 CFR 46.116(a)&(b)], every consent form must include:

  1. A statement that the study involves research, an explanation of the purposes of the research and the expected duration of the subject’s participation, a description of the procedures to be followed, and identification of any experimental procedures;
  2. A description of any reasonably foreseeable risks or discomforts to the subject;
  3. A description of any benefits to the subject or to others that may reasonably be expected from the research;
  4. A disclosure of appropriate alternative procedures or courses of treatment, if any, that might be advantageous to the subject;
  5. A statement describing the extent, if any, to which confidentiality of records identifying the subject will be maintained;
  6. For research involving more than minimal risk, an explanation as to whether any compensation and/or medical treatments are available if injury occurs and, if so, what they consist of, or where further information may be obtained;
  7. Names and contact information of individuals able to answer pertinent questions about the research and research subjects’ rights, and contact information of those to notify in the event of a research-related injury to the subject; and
  8. A statement that participation is voluntary, refusal to participate will involve no penalty or no decrease in benefits to which the subject is otherwise entitled, and that the subject may discontinue participation at any time without penalty or loss of benefits to which the subject is otherwise entitled.

Additionally, regulations require the following information to be provided, when applicable:

  1. A statement that the particular treatment or procedure may involve risks to the subject (or to an embryo or fetus, if the subject is or may become pregnant) which are currently unforeseeable;
  2. Anticipated circumstances under which the subject’s participation may be terminated by the investigator without regard to the subject’s consent;
  3. Any additional costs to the subject that may result from participation in the research;
  4. The consequences of a subject’s decision to withdraw from the research and procedures for orderly termination of participation by the subject;
  5. A statement that significant new findings developed during the course of the research which may relate to the subject’s willingness to continue participation will be provided to the subject;
  6. The approximate number of subjects involved in the study.

Additional Seattle University requirements:

  1. Researchers must inform subjects of any conflict of interest they have in the research.
  2. If researchers will provide incentives for study participation, the consent form must describe the terms of the incentive and the conditions under which subjects would receive partial or no incentive (e.g., withdrawing from the study before participation is completed).
  3. The form should not say that the study is “sponsored” or “endorsed” by the University. The group conducting the study can be identified in the text of the document, but not at the very top of a consent form, and the identification should not advertise the group.
  4. If the project is conducted by faculty or staff, the first page of the consent form must include the Seattle University name and logo, and the Principal Investigator's name and Department and/or College.
  5. For student projects, “Seattle University” must appear at the top of the first page, and advisers’ names, departments, and office numbers should be given with the student’s name and contact information.

Children and Adolescents

Researchers must obtain parental permission for studies involving children under the age of majority (18 years old in Washington State). If the research involves greater than minimal risk, signatures from both parents are required unless: only one parent has legal responsibility for the care and custody of the child, or if one parent is deceased, unknown, or incompetent. On some occasions, the IRB can grant a “waiver of parental permission” (see Waiver or Alteration of Consent below), if the research involves minimal risk, if it will yield significant benefits to the population being studied or a public program, and/or if obtaining parental consent would pose a considerable risk to the potential subjects. Additionally, for some research, the requirement for parental permission may be inappropriate. For example, research involving older adolescents who, under applicable law, may consent on their own behalf for selected treatments (e.g., treatment for venereal disease, drug abuse, or emotional disorders). In other research (e.g., research on child abuse or neglect), the parents' interests may not adequately reflect the child's interests. In these cases, primary investigators must ensure alternative procedures for protecting the rights and interests of the children asked to participate, including, perhaps, the court appointment of special guardians.

Parental permission is documented similarly to an adult subject consent form, in which “your child” is substituted for “you.” Once the researcher has obtained written parental permission, the agreement of the child is required. (In therapeutic settings, parental permission overrules a child’s decision not to participate.)

A child’s agreement is documented with an “assent form,” a child-friendly document that outlines the essential information about the research. Most children 8 years old and above have the cognitive and emotional maturity to understand a research project and should be given the opportunity to assent to participation. Some children under the age of 8 may also be capable of granting and withholding assent, and the IRB asks researchers to be sensitive to the needs of these children on an individual basis.

In addition, a researcher must complete and submit Appendix B.Research with Minors Request.

Language Barriers

For research involving non-English speaking subjects, a protocol submission must include both English-language and translated consent forms. An explanation of the translations and the expertise of the translator should be provided for IRB review. (The IRB may consult with language experts or require a “back-translation” into English.) The researcher should also include a confidentiality agreement to be signed by the translator.

As an alternative to translated consent forms, an oral presentation of informed consent information together with a short form written consent document (stating that the elements of consent have been presented orally) and a written summary of what is presented orally can be approved by the IRB. A witness to the oral presentation is required, and the subject must be given copies of the short form document and the summary. If this situation applies to a proposed study, researchers must include Appendix A.Oral Consent or Alteration of Consent Request with the initial protocol.

When this procedure is used with subjects who do not speak English:

  1. the oral presentation and a short, simple consent document should be in a language understandable to the subject;
  2. the IRB-approved English language informed consent document may serve as the summary; and
  3. a witness fluent in both English and the language of the subject must be present to verify consent.

At the time of consent, the following signatures should be obtained (unless the researcher legitimately justifies reasons for not collecting signatures in the Appendix A.Oral Consent or Alteration of Consent Request):

  1. the shorter, simple consent document should be signed by the subject (or the subject's legally authorized representative);
  2. the summary (i.e., the English language informed consent document) should be signed by the person obtaining consent as authorized under the protocol; and
  3. the simple consent document and the summary should be signed by the witness. When the person obtaining consent is assisted by a translator, the translator may serve as the witness.

The IRB must receive all foreign language versions of the simple consent form as a condition of approval (46.117(b)(2)).

Sometimes a subject understands English but does not read or write English. An impartial witness should document that the subject understands the study and the consent process and consented to participate.


In some cases, a researcher may wish to employ deception (deliberately withholding information from subject participants) for the purpose of securing subject participation and/or to prevent potentially biased reporting of data or information by the subject. Before approving protocols involving deception, the IRB must verify that the following conditions will be met:

  1. Deception is necessary due to the lack of any other alternative procedure for data collection.
  2. Deceptive procedures will not place subjects at greater financial, physical, psychological, or social risk.
  3. The data collection/experiment will be followed by careful debriefing sessions in which the subjects are fully informed of the nature and purpose of the deception.

The procedures for deception must meet the guidelines established by the discipline of the investigator through its professional code of ethics. A researcher must complete and submit Appendix F.Use of Deception Request with the protocol application.

Waiver or Alteration of Consent

On some occasions, Federal regulations for human subjects research permit a waiver of the requirement for informed consent, or an alteration of consent, including waiving parental permission. For example, a study may investigate certain aspects of public benefit or service programs but may not be practicably carried out without waiver or alteration of the consent process (see 45 CFR 46.116[c]). Only the IRB may approve waivers or modifications of the consent process, after having determined:

  • the research involves no greater than minimal risk to the subjects;
  • the waiver or alteration will not adversely affect the rights and welfare of the subjects;
  • the research would be impracticable without the waiver or alteration; and
  • the subjects will be informed of the study when it is over (if at all possible).

If this situation applies to a proposed study, researchers must include Appendix A.Oral Consent or Alteration of Consent Request with the submitted protocol.
