You are invited to participate in this research project, which is called the ‘Eating Disorders Genetics Initiative’, or EDGI.
We are seeking people 18 years of age and over who have experienced an eating disorder (ED) at any time in their life to participate. We are also seeking people who have never had an eating disorder (controls).
This Participant Information Sheet/Consent Form tells you about the research project. It explains what is involved in the study to help you decide if you want to take part.
Please read this information carefully. Ask questions about anything that you don’t understand or want to know more about. Before deciding whether or not to take part, you might want to talk about it with a relative, friend or your doctor.
If you decide you want to take part in the research project, you will be asked to provide your consent online. You will be able to save an electronic copy of this Participant Information Sheet and Consent Form to keep.
Genes are made of DNA – the chemical structure carrying your genetic information that determines many human characteristics such as the colour of your eyes or hair. Researchers study genes in order to understand why some people have a certain condition such as Anorexia Nervosa and why some people do not. Understanding a person’s genes may also explain why some people respond to a treatment while others don’t, or why some people experience side effects and others do not.
Anorexia Nervosa (AN) is a severe mental illness causing significant disability and burden, afflicting 3% of females and 0.3% of males. Bulimia Nervosa (BN) and Binge Eating Disorder (BED) are more common than AN and carry substantial morbidity and profoundly impact quality of life. Researchers so far have only scratched the surface in understanding the causes of eating disorders. EDGI researchers propose to use genetics to understand the biology of Eating Disorders and, in turn, the pathways and systems that influence these complex diseases.
We are seeking 3,500 participants who have experienced an eating disorder at some time in their life to help us reach this goal. We are also seeking people who have never had an eating disorder (controls). In research, case/control studies compare groups of people with different experiences (e.g. with and without AN) but who are otherwise similar, for instance, in terms of their age, background, and geographic location. This enables researchers to be certain any results they find are from the effect being measured, and not something else.
This research has been funded by a grant from the National Institute of Health (NIH), USA.
There are 3 parts to this study:
(i) In the first part of this study, you will be asked to complete an online consent form. We will then ask you for your contact details so we can contact you about the study;
(ii) After giving your consent, you will be asked to complete an online questionnaire about eating disorders and other health information.
(iii) Depending on your responses to the core online questionnaire, you may be asked to donate a saliva sample. We will extract your DNA from your sample to investigate genetic risk factors for eating disorders. To collect your sample, we will send you a specialised collection container for your sample. The collection kit is easy to use and the sample can be collected in your own home at your convenience. You will be asked to return this sample via Australia Post to our laboratory, at no cost to you.
Altogether, completing the online questionnaire will take approximately 45 minutes, but may take less time. For your convenience, the survey is designed so that you can start a module and return to it later where you left off.
There are no additional costs associated with participating in this research project, nor will you be paid.
Participation in this research project is voluntary. If you do not wish to take part, you do not have to. If you do not wish to take part you do not have to do anything. If you decide to take part and later change your mind, you are free to withdraw from the project at any stage.
This study is unlikely to be of any immediate and specific benefit to you. Extensive research is required to find answers to the questions we are studying. However, future medical or scientific discoveries may come from the research in which you participate. These may help improve the available treatments and outcomes for people suffering Eating Disorders.
You may feel that some of the questions we ask in the questionnaire are stressful or upsetting. If you do not wish to answer a question, you may skip it and go to the next question, or you may stop immediately. If your responses to questions in the online questionnaire indicate that you are at significant risk of serious harm, you will be provided with advice on how to seek appropriate counselling, support or formal health care.
All personal and questionnaire data collected, and information linked for the study remains confidential in accordance with the National Health and Medical Research Council (NHMRC) ethical guidelines and the Privacy Act. Your personal details, questionnaire data and genetic data will all be stored separately. The only link between your personal details and your other data is your participant identification number. Linking your personal details and other data using this number is restricted to members of the QIMR Berghofer research team. All information about you will be stored securely, with access restricted to members of the research team.
The researchers will store your other personal, questionnaire and genetic information indefinitely at QIMR Berghofer Medical Research Institute. This information may continue to be valuable to researchers many years into the future, and may be considered for use in future, related projects. Before any future work proceeds it will be subject to approval by the relevant ethics committees.
Your genetic information and some of your questionnaire information (not your name or other personal details) may eventually be put into an international genetics data repository. Information in the database will be available only to researchers from around the world who are approved to study how genes cause a variety of health conditions. These scientists will not know your name or other personal information we learn about you.
Results of this research project may be presented in scientific papers in medical literature, or in public talks, but your identity will not be revealed. The data collected as part of this study will be combined at analysis with the data from many other people, and as such there will be no way of identifying you as a participant.
In accordance with relevant Australian privacy and other relevant laws, you have the right to request access to the information about you that is collected and stored by the research team. You also have the right to request that any information with which you disagree be corrected. Please inform the research team member named at the end of this document if you would like to access your information.
By confirming your consent online you consent to the research team collecting and using personal, questionnaire and genetic information about you as described for the research project.
We will use your biological sample to extract one or more samples of DNA. The research team will then look for differences and similarities between participants’ DNA samples. This information can help us understand why some people have a certain eating disorder and some people do not.
Your biological sample and extracted DNA samples will be stored securely at QIMR Berghofer Medical Research Institute along with samples from many other people. They will be re-identifiable, which means that they will be stored with a barcode label, and can be identified as yours even though your personal details are stored separately. Linking your personal details with your biological sample or DNA using the barcode is restricted to members of the QIMR Berghofer research team.
We may send part of your DNA to another laboratory (which may be overseas) for genetic processing and analysis. This is called genotyping. If this occurs, your part sample will only be labelled with a number, and transported along with samples from many other people. No information about you will be sent to or accessible by the other laboratory. Any sample remaining after genetic processing or analysis by another laboratory will be destroyed.
We will store the remainder of your DNA sample indefinitely. We may send a small portion of your DNA to a scientific research repository established by the National Institutes of Mental Health (NIMH) in the USA for indefinite storage. If this occurs, your part sample will only be labelled with a unique number, a number not used in any other phase of the study, and transported along with samples from many other people. No information about you will be sent or accessible by this repository. Your sample will be used for future research on psychiatric disorders, related medical conditions and/or other health conditions. Access to the repository is strictly limited and all applications will be reviewed by the NIMH review panel. QIMR Berghofer will store any remaining DNA samples for use in future research studies that may or may not be related to the original research project. The purpose of storing these types of samples is to answer questions in the future, so we expect to keep your samples for a long time.
This research is not intended for the purpose of treating any health problems you may have. Participation in this research study does not take the place of visits to a doctor or other health professionals.
Your information will be used for research purposes and you will not be given any clinical results from this study. Your information will be analysed in combination with information from other participants in this study. The nature of the research means that the data is de-identified prior to analysis, and only results of a global (not individual) nature will be produced. It will therefore not be possible to provide any individual results from the study.
All research in Australia involving humans is reviewed by an independent group of people called a Human Research Ethics Committee (HREC). The ethical aspects of this research project have been approved by the HREC of the QIMR Berghofer Medical Research Institute (QIMRB-HREC).
This project will be carried out according to the “National Statement on Ethical Conduct in Human Research (2007)”. This statement has been developed to protect the interests of people who agree to participate in human research studies.
Participation is voluntary and you can choose not to participate.
