Parental Permission Form

(< 18 years of age)

The Centers for Disease Control and Prevention’s (CDC) National Center for Environmental Health (NCEH) and the Agency for Toxic Substances and Disease Registry (ATSDR) is conducting this research study. Recently, your child took part in an ATSDR study that measured PFAS in your child’s blood. You and your child agreed to hear about new ATSDR studies. This makes your child eligible for this new research study.

KEY THINGS TO KNOW ABOUT THIS RESEARCH

AUTHORITY: 1980 Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), as amended by the 1986 Superfund Amendments and Reauthorization Act (SARA) (42 U.S.C. 9601, 9604), and the Public Health Service Act Section 301 (42 U.S.C. 241) and Section 311 (42 U.S.C. 243)

PURPOSE: To see if a person’s PFAS blood levels may be related to viral illnesses. This can include getting the COVID-19 virus.

WHO CAN TAKE PART: About 2,800 eligible adults (≥ 18 years of age) and 370 eligible children (4-17 years of age) who took part in an earlier ATSDR PFAS study.

• Eligible children 4-17 years (including pregnant girls) can enroll, with the exception noted below.

• People who are prisoners or under house arrest are not eligible to take part in this study.

Eligible adults aged 18 years and older (including pregnant women) can enroll (see adult consent form).

A parent can enroll more than one child. In this case, ATSDR will enroll each child separately. Parents, if eligible, may also enroll in the adult study.

You will not need any in-person contact with any CDC/ATSDR team members.

EXPECTED TIME IN THE STUDY: About 2-½ hours over a year-long period. You and your child are asked to answer five 30-minute surveys at home. The five surveys will be spaced three months apart, and each follow-up survey will ask about the three-month time period since the previous survey was completed.

PROCEDURES: If you agree for your child to take part, we ask you to sign this permission form. Next, if your child is 7-17 years of age, they should sign the assent form. Then, we ask you (with your child’s help) to answer the first survey that is attached to this permission form. You are asked to mail them both back to CDC/ATSDR in the addressed pre-paid envelope. You can choose to complete the next four surveys through an online platform or by mail. CDC/ATSDR will link new survey answers to your child’s earlier blood PFAS measures and data. No new blood or urine will be collected for this study.

Between the surveys, we will ask you to keep track of certain things, such as symptoms that could indicate a viral infection, exposures to people who have or might have COVID-19, and vaccinations. Keeping track of these things will help you to be able to provide accurate information on the follow up surveys.

BENEFITS: There are no direct benefits for your child to be in this study. Your child taking part will help us learn if a person’s PFAS blood measures may be related to viral illnesses. This can include the COVID-19 virus.

RISKS: The risks of taking part in this research are minimal. These risks are about the same as those your child would face in daily life. There is a small chance of an accidental breach of your child’s private information. We want you to know that our study staff are trained to take all necessary steps to protect your child’s private information to avoid this risk.

COSTS: You do not have to pay for your child to be part of this study.

INCENTIVES: We very much appreciate you and your child taking part in this study. Your child will receive a $10 gift card for each completed survey. If you (with help from your child) completes all five surveys, your child will receive an additional $25 gift card, for a total of $75 for completing all five surveys.

CONFIDENTIALITY: A Certificate of Confidentiality covers this research. CDC/ATSDR cannot be forced to release information that could identify your child even under a court order or subpoena (unless you choose to release it). You should know, however, that CDC/ATSDR may tell local authorities if harm to you, harm to others, or if child abuse or neglect becomes a concern.

IT IS YOUR DECISION: You and your child may freely choose to, or refuse to, take part in this research. You can stop at any time. You and your child can refuse to answer any questions on any of the surveys. There is no penalty for refusing to take part or for leaving the study at any time.

FOR QUESTIONS ABOUT THIS STUDY: If you have any questions about the study, or if you and your child decide to leave this study, please contact the Principal Investigator, Breanna Alman at (xxx) xxx-xxxx or [email protected].

FOR QUESTIONS ABOUT YOUR RIGHTS IN RESEARCH OR ABOUT A RESEARCH-RELATED INJURY: For questions about your rights in taking part in this study, call the CDC/ATSDR Human Research Protection Helpline at (800) 584-8814. Be sure to say your call is about CDC Protocol No. 7360. Leave your name, contact information, and a description of your concern.

DETAILS ABOUT THIS RESEARCH

MORE ON WHAT TO EXPECT DURING THIS STUDY:

• This research is solely a survey-based study. It does not involve collecting any samples from you (like blood or urine) or your home (like tap water).

• We are providing you with two copies of this form, one to keep and one to sign and return.

• Once this permission form is signed, you and your child are asked to complete the attached first survey.

• If your child is 7-17 years of age, they will also need to sign the attached assent form.

• Next, you are asked to return both the permission and assent (if applicable) forms and the completed survey to us in the mail.

• The completed survey must be returned with the signed permission and assent (if applicable) forms. Otherwise, we will not be able to use the information from your child’s survey.

• There is a section on the consent form to tell us how you want to receive your child’s four follow-up surveys. You can choose a secure online platform called REDCap or a paper survey in the mail.

  • If you choose the REDCap option, you need to provide us your child’s personal e-mail address. We will email you with instructions and a link for each follow-up survey. Please note – each participant, including children, needs their own, unique email address.

  • If you choose the mail option, we will send a paper survey with an addressed pre-paid envelope for each follow-up survey.

• With your consent, CDC/ATSDR will link your child’s new survey answers to your child’s earlier blood PFAS measures and data.

• Between surveys, we ask you to keep track of things like symptoms, exposures to people who might have COVID-19, and vaccinations, using the Symptom Diary included in this packet.

QUESTIONS WE WILL ASK: On the first survey, we will ask questions about your child’s medical history, flu vaccines, school or work-related situations, COVID-19 exposures, and COVID-19 vaccinations. On the follow-up surveys, we will ask about any changes in your child’s medical history, updates in vaccinations, changes in school or work situations, viral symptoms and testing, and COVID-19 exposures since the previous survey.

MORE ABOUT CONFIDENTIALITY: A Certificate of Confidentiality covers this research. CDC/ATSDR must protect the privacy of persons who are subjects of this research under subsection 301(d) of the Public Health Service Act (PHSA) [42 USC §241(d)]. CDC/ATSDR and their contractors cannot be forced to release information that could identify you or your child even under a court order or subpoena (unless you choose to such a release). You should know, however, that CDC/ATSDR may tell local authorities if harm to you, harm to others, or if child abuse or neglect becomes a concern.

You should know that a Certificate of Confidentiality does not prevent you from voluntarily releasing information about your child or his/her involvement in this research. If you want your child’s research information released to an insurer, medical care provider, or any other person not connected with the research, you must provide consent to allow CDC/ATSDR to release it.

CDC/ATSDR and their contractors are required to ensure that any investigator or institution not funded by CDC/ATSDR, who receives a copy of identifiable, sensitive information protected by a Certificate, understand they are also subject to the requirements of Subsection 301(d) of the PHSA.

YOUR PRIVATE INFORMATION: We will store your child’s answers and test results using a study number, not his/her name. We will keep your child’ records in locked files at CDC/ATSDR. CDC/ATSDR and their contractors will protect any computer files with your child’s information. Only study staff with a need-to-know will have access to your child’s information and test results. All study staff will take training on how to protect the privacy of people who take part in this research.

CDC/ATSDR might remove your identifiers to make datasets to share with other investigators for future research. To do this, CDC/ATSDR will not seek additional informed consent from you.

USE OF COLLECTED INFORMATION: We will combine everyone’s responses to get a picture of the health issues of the people included in the study as they may relate to PFAS. We will write reports or publish articles about the study results. These reports or articles will be available to the public after the study is finished. The reports will not identify who took part in the study.

THINGS TO KNOW ABOUT THIS STUDY

WHO IS DOING THIS STUDY: CDC/ATSDR are public health agencies that do research. A research study is when people like scientists, doctors, and teachers collect information to try and answer questions about certain things. If you have any questions about the study, your parents can help answer them, and you can also ask us.

PURPOSE: We are doing this study to try to find out if some things that may be found in people’s bodies could make it easier for them get a virus infection (like a cold or the flu) or make the virus infection worse.

We sent your parents a letter asking if we have their permission for you to be a part of the study. Even if they said it was ok, it is still your choice to make and you can say yes or no.

WHO CAN TAKE PART: ATSDR wants to enroll 2,800 eligible adults (≥ 18 years of age) and 370 eligible children (4-17 years of age) who took part in an earlier ATSDR PFAS study. You will not need any in-person contact with any CDC/ATSDR team members.

EXPECTED TIME IN THE STUDY: About 2-½ hours over a year-long period. Your parent (with your help) is asked to answer five 30-minute surveys at home. The five surveys will be spaced three months apart.

WHAT WILL YOU DO: If you agree and your parents give permission, we ask your parents to answer some questions about you. You can help your parents answer the questions. The questions are on a paper that came in the mail with this letter. If you or your parents need help answering the questions, they can ask us by calling xxx-xxx-xxxx or sending an email with your question to [email protected].

In about 3 months, we will send the next set of questions to answer. There will be three more sets of questions after that. Remember, you can help your parents answer any of the questions.

Section 4. Questions specific to COVID-19

This section relates to COVID-19 or a COVID-19-like illness. The items listed below could have happened more than once. For each item, please list, to the best of your recollection, the number of times it occurred since January 1, 2020 and use the date columns to list the approximate date(s), starting with the earliest occurrence. If the event occurred more than twice, please list the remaining dates together in the last column. Enter the dates using 2 digits for the month and 4 digits for the year (example: 01/2020)

For questions below that ask about COVID-19 testing, please note:

There are different types of COVID-19 tests available. Some test for current infection and some test for past infection.

• A viral test tells you if you have a current infection. Two types of viral tests can be used: nucleic acid amplification tests (often called PCR tests) and antigen tests. The viral test involves collecting a specimen with a swab from the nose, nasopharynx, mouth, or throat; or collecting saliva.

• An antibody test (also known as a serology test) is a blood test that might tell you if you had a past infection. Antibody tests are not used to diagnose a current infection.

Please remember: If you are a parent filling this survey out for your child, questions about “anyone else in the household” refers to anyone besides the child you are answering the questions for (including yourself).

Since January 1, 2020:	NO	YES	If YES, number of times	First approx. date (month/year)	Second approx. date (month/year)	Other approx. dates (month/year)
