The research holds out the prospect of benefit to children and involves:

• A condition uniquely affecting/manifesting in children (e.g., pediatric cancer or systemic lupus erythematosus).
• A condition affecting both adults and children, where adult studies have been done but child-specific data is still needed (e.g., many drug trial conditions).
• An area of psychology or sociology specifically related to children (e.g., adolescent depression, childhood abuse).
• A pediatric condition linked to a different adult condition, so data could inform treatment of adult condition (e.g., Down’s syndrome/Alzheimer’s disease).

Note: Many other examples could be listed.

Minimal risk means that the probability and magnitude of harm or discomfort anticipated in the 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 21 CFR 50.3].

Describe the study risks in the IRB Application, clarifying what would be standard of care for the subject group(s) and how the research procedures differ from that standard of care. The consent/assent forms need only discuss in detail procedures (and their risks) that are being done specifically for purposes of the study. Also, keep in mind that what constitutes "daily life" or a "routine test” may not be constant over childhood, among children of the same age, or before and after the occurrence of a disease or condition. 

Description: "Research not involving greater than minimal risk."

Consent/Assent: 

• Permission from ONE parent/legal guardian may be sufficient.
• Assent of child (if child is 7 years of age or older).
• See the Waiver of Consent guidance for info on when the IRB may waive consent/assent for non-FDA-regulated research.

Type of Review: Generally, expedited review by the IRB. See the Levels of Review page for a list of expedited review categories. Occasionally, full committee review may be required.

Examples: 

• A study involving one blood draw (no more than the lesser of 50 ml or 3 ml/kg in an 8 week period) in healthy 10-year-old subjects.
• Other procedures that usually qualify as minimal risk include urinalyses, EEGs, allergy scratch tests, and minor changes in diet or daily routine.

Description: "Research involving greater than minimal risk, but presenting the prospect of direct benefit to the individual subjects.”

Consent/Assent:

• Permission of ONE parent/legal guardian may be sufficient.
• Assent of child (if child is 7 years of age or older).

Type of Review: Full committee review by IRB.

Examples:

• A study evaluating a new type of therapy to treat bulimia nervosa.
• A Phase II study using an experimental chemotherapeutic regimen for children with malignant brain tumors for whom standard therapy has failed.

Note: Although most clinical trials fall into Category 2, it is sometimes difficult to determine what the “prospect of direct benefit” is, as in a study that includes a control group whose participants face less risk than the active group but also less prospect for benefit.

Description: “Research not otherwise approvable which presents opportunity to understand, prevent, or alleviate a serious problem affecting the health or welfare of children." The IRB must agree with this determination.

The Secretary of the U.S. Department of Health and Human Services — after consultation with a panel of experts and following an opportunity for public review and comment — must either approve or deny approval of the study. The OHRP website includes a detailed description of this process. Note: Category 4 research is very rarely approved.

Consent/Assent:

• Permission of BOTH parents/legal guardians, unless one parent is deceased, unknown, incompetent, not reasonably available, or does not have legal responsibility for the custody of the minor.
• Assent of child (if child is 7 years of age or older).

Type of Review: Full committee review by the IRB and by DHHS.

Example: A study examining sleep mechanisms in children to better understand sleep-related diseases. Involves 13- to 17-year-old adolescents undergoing 3 hospital visits for IV infusion of acetate and glucose followed by MRI, in normal and sleep-deprived groups.

In most cases, children this young will not be able to participate in the assent process, and only a permission form for the parents or legal guardians will be needed.

Consent/Assent Notes:

1. Base the parental permission form on the IRB sample consent forms, and refer to the subject as "your child" throughout the form.
2. The signature line of this form should be preceded by an explanatory statement such as: “The person being considered for this study is unable to consent for herself/himself because s/he is a child. By signing this form, you are giving permission for your child or ward to participate in the study.”
3. In certain cases, the PI may deem a child in this age range capable of being involved in the assent process. If so, give the child a simple verbal explanation of what will happen to him/her, and then document on the parental permission form or in the study records that you obtained verbal assent.

In most cases, children this age will be able to participate in the assent process, using a simplified assent form. A separate, more detailed permission form will be needed for the parents or guardians.

Consent/Assent Notes:

1. A very simple assent form is needed, based on the IRB Sample Assent Form #1 or #2. Refer to the subject throughout as “you.” The child should sign the form if possible. If not, the form or study records must still document that verbal assent was obtained.
2. Base the separate parental permission form on the IRB sample consent forms, and refer to the subject as "your child" throughout the form.
3. The signature line of the parent’s or guardian’s form should be preceded by an explanatory statement such as: “The person being considered for this study is unable to consent for herself/himself because s/he is a child. By signing this form, you are giving permission for your child or ward to participate in the study.”

In most cases, adolescents should be fully informed about a study and give assent to their own participation in the research. There are two ways to document their assent.

Adolescent Consent Documentation-Option A

Option A is usually preferred. One form is written for the adolescent subject and the parents or guardians.

Consent/Assent Notes:

1. This assent/consent form should use clear, straightforward language (eighth-grade reading level).
2. Base the assent/consent form on the IRB sample consent forms, referring to the adolescent subject throughout as “you.” Both the adolescent and the parents or guardians are asked to sign this form, with a signature line for the adolescent first.
3. The signature line for parental consent/permission should follow, preceded by an explanatory statement such as: “The person being considered for this study is legally unable to consent for herself/himself because s/he is a child. By signing this form, you are giving permission for your child or ward to participate in the study.”

Adolescent Consent Documentation-Option B:
A simplified assent form is written for the adolescents. A separate, more detailed permission form is written for the parents or guardians.

Option B is reserved for studies where Option A is not feasible or appropriate. This option can be used for studies with a very complex protocol and/or involving adolescent subjects whose medical condition demands a simpler form than the adult’s form, even when the adult’s form is written at an eighth-grade level (e.g., see Sample Assent Form #3).

Consent/Assent Notes:

1. This adolescent assent form should be simpler than the adult consent form for the same study. Base the assent form on IRB Sample Assent Form #2 or #3, referring to the subject throughout as “you.” Only the adolescent is asked to sign this form. (Note that assent forms written for 7-12 year olds are often too simple for adolescents, but can be expanded upon or adapted as appropriate).
2. Base the separate parental permission form on the IRB sample consent forms, and refer to the subject as "your child" throughout the form.
3. The signature line of parent’s or guardian’s form should be preceded by an explanatory statement such as: “The person being considered for this study is legally unable to consent for herself/himself because s/he is a child. By signing this form, you are giving permission for your child or ward to participate in the study.”

• Permission from one parent/legal guardian: Generally sufficient for research in categories 1 and 2 (described above), although the IRB may require permission from both parents/legal guardians in some circumstances.
• Permission from both parents/legal guardians, unless one parent is deceased, unknown, incompetent, not reasonably available, or does not have legal responsibility for the custody of the child: Required for research in categories 3 and 4 (described above).

Signed parental permission forms should be retained with the study records.

Document the assent of children who are deemed capable in one of several ways (upon approval by the IRB):

1. Assent form signed by child (e.g., see Adolescent Assent-Option B, Sample Assent Form #3) is retained with the study records.
2. Assent form signed by person conducting the assent discussion (PI or other study staff member) is retained with the study records.
3. Certification of discussion/assent signed by person conducting the assent discussion (PI or other study staff member) is appended to parental permission form; or retained separately with the study records.

In certain cases, the IRB may consider waiving the requirement to obtain children’s assent, for example:

• “The capability of some or all of the children is so limited that they cannot reasonably be consulted;” or
• “The research holds out a prospect of direct benefit that is important to the health or well-being of the children and is available only in the context of the research” [45 CFR 46.408 21 CFR 50.55]. Here the parents’ right to make medical decisions for their child may come into conflict with the child’s right to give or withhold assent. In this situation, assent may not be mandatory, though it always should be sought.

In such cases, the PI may propose a waiver of child’s assent in the IRB application. The IRB’s decision about waiver of assent will depend on the specifics of the study.

Consent/Assent Notes:

• If the child is considered capable of providing assent, always provide a simple verbal explanation of what will happen to him/her and the opportunity for questions and discussion.
• Even if the requirement for assent is waived, it is always preferable to seek the child’s assent, if possible.
• Document on the parental permission form or in the study records that the child was appropriately informed about the study.

FDA-Regulated Studies

PARENTAL PERMISSION FOR CHILDREN’S ENROLLMENT CANNOT BE WAIVED. Subpart 21 CFR 50 lacks the provision for waiver of parental permission, because the FDA says it does not oversee studies for which such a waiver is appropriate. See the section Legal Exceptions Permitting Certain Minors to Consent for info on circumstances when minors may consent to research for themselves.

For Non-FDA-Regulated Studies

See the Waiving Informed Consent page for information on when consent may be waived completely for a study.

The IRB may also waive parental permission in some cases in which the study "is designed for conditions or for a subject population for which parental or guardian permission is not a reasonable requirement to protect the subjects (for example, neglected or abused children)." There must be “an appropriate mechanism for protecting the children who will participate as subjects in the research is substituted, and provided further that the waiver is not inconsistent with Federal, State, or local law.” [45 CFR 46.408]

Examples where parental permission MAY be waived:

• Research on child abuse or neglect, or research that is reasonably likely to elicit information identifying child abuse or neglect, where there is serious doubt as to whether the parents’ interests reflect the child’s interests. [45 CFR 46.408(c)].
• Research on people under 18 who are in circumstances where they are clearly outside of parental influence or control. The IRB would evaluate each study carefully to determine whether parental permission is not a reasonable requirement to protect the subjects. Note: Some people under 18 who are living independently may be able to consent for themselves without a waiver of parental permission.

Investigators should address all such consent concerns for research with minors, including arguments for waiver of standard consent procedures in the IRB Application.

Minors 12 years of age or older may consent on their own behalf for

• Outpatient mental health treatment or counseling (in limited circumstances) excluding ECT, psychosurgery or psychotropic drugs (Sec 6924);
• Medical care for the diagnosis or treatment of reportable infectious, contagious, or communicable/sexually transmitted diseases (Sec 6926);
• Medical care for the diagnosis or treatment of the condition and collection of medical evidence with regard to alleged rape (Sec 6927) or alleged sexual assault (Sec 2928);
• Medical care and counseling for the diagnosis and treatment of a drug- or alcohol-related problem (if the treating physician deems and documents that parental involvement is inappropriate), excluding narcotic replacement drugs (Sec 6929).

Minors may consent for themselves to medical care related to the prevention or treatment of pregnancy, but not necessarily to sterilization (Sec 6925).

Emancipated minors — those who are either

• married or divorced, or
• on active duty in the U.S. armed forces, or
• emancipated by a court —

have the legal right to consent on their own behalf to medical, dental or mental health treatment. They also have extensive other rights to enter into legal and business arrangements, and so can consent to be included in other research (such as surveys or interviews) (Sec 7000-7143).

• While the IRB is not legally required to apply the special protections of Subpart D for children set forth in 45 CFR 46 and 21 CFR 50 for research involving the categories of minors above, the IRB may apply special protections depending on the specific research study.
• In certain cases, the IRB may determine that certain groups of minors that otherwise may legally consent should be excluded from a research study in light of potential risks or due to the investigational nature of the trial (e.g., phase I or phase II trials of investigational new drugs or devices).
• Unless the PI obtains a Certificate of Confidentiality, the minor’s parents or legal guardians may obtain medical information relating to the minor’s drug or alcohol abuse, care even if the minor objects.

When children are asked to do something by parents, doctors, teachers or other adult authorities, they often feel implicit pressure to agree. Similar issues with social or peer pressure (e.g., for studies in educational settings) may also arise in recruiting children to participate in research.

Describe how you plan to minimize implicit pressure to participate in the "Recruitment" section of the IRB Application. As with all consent and assent forms, the freedom to decline participation should be made clear.

In designing studies involving children, consider any special arrangements for participation, such as scheduling, parking and food, and discuss them with parents if appropriate. Though such information is not required, it could be helpful to parents in deciding about or planning for study participation.

Examples of special study arrangements to consider:

• If the subject is to receive a series of procedures or tests, can these be coordinated with school and/or work schedules?
• Are there siblings who will need childcare or other provisions made?
• What about transportation and/or parking permits for the facility where the research is being conducted?
• Will subjects or their family members need snacks or meals during the study?

Consider how you will handle such situations should they arise. The permission and/or assent form should describe plans for disclosure — or non-disclosure — of such information to parents, legal authorities and the subjects themselves.

• In some cases, it may be appropriate for the PI to seek an NIH Certificate of Confidentiality.
• As with all UCSF consent forms, complete confidentiality should never be promised. See IRB sample consent forms for recommended wording.

• If there is continued interaction with participants who were first enrolled as children, re-consenting is required when a participant's legal status changes from minor to adult. 
• If the study does not involve ongoing interactions or interventions with the participants but continues to mee the definition of 'human subjects research' (such as ongoing analysis of specimesn or data), re-consent from the now-adult participants is required unless a waiver of consent is granted. 
• A waiver of documentation of consent may be granted by the IRB if it meets the regulatory requirements specified in 45 CFR 46.117(c). This includes scenarios where: 
  • The research involves no more than minimal risk to the participants.
  • The research could not practicably be carried out without the waiver. 

First, obtain support from the educational community of their target school/subject group. This may include contacting school district officials, the local PTA, and/or the principal of a particular school. School officials and/or teachers may approve recruitment for a study, but they do not have authority to give permission for participation of individual children in research — only a parent or guardian, with the child’s assent, can do so.

The IRB is unlikely to approve use of “implied consent” — e.g., a child brings home information about participating in a study at school, and absence of response is considered agreement. In most cases, obtaining “active consent” via permission and assent procedures appropriate for the subject group(s) is required.

Parental Consent for Children to Participate in Research (§51513): For K-12 students — tests, questionnaires, surveys, or examinations containing any questions about the pupil's or the pupil’s family’s personal beliefs or practices in sex, family life, morality and religion require written parental consent (permission).

Pay particular attention to recruitment issues such as scheduling, payment and minimizing pressure to participate, discussed in the section above.

If the study will be conducted during school hours, an equivalent alternative activity should be offered for students who do not wish to participate.
