About the Study

1. What happens if we lose or forget our ID number?      

Just send an email to and I’ll send it to you again.                   

2. How do I find out about the results of the study?

Once the study is published, we’ll add information about the findings on this website, as well as a link to the published paper.

3. Has this study been ethically approved?

Yes! This study has been reviewed and approved by the College Ethics Committee at Royal Holloway, University of London.

4. How do I download the app for the second part of the study?

The task for the app is still being finalised. In the meantime, you can start Part 1 of the study as soon as you have submitted a consent form and received an ID number via email. If you have signed up to participate, we will email you to let you know when the app is available for the Part 2 tasks.

5. What types of operating system does the app work on?

At the moment, we, unfortunately, can only run the test on iPhones. Hopefully, we will be able to expand to different operating systems in the future. Until then, only people who own iPhones, or have access to one, can complete the tasks.

6. What if I don’t have an iPhone?

If you don’t have one, you could try to find out if anyone you know has one (and if they would be able to let you borrow it for a short time to complete the task). If this isn’t possible, you can still take part in the study (you just won’t be able to take part in the iPhone task).

7. Do we have to complete all the tasks in one go?

No, you don’t have to. You close the browser at any point when you’re completing the questionnaires and have a break for as long as you want. When you decide to carry on, you can click on the same link and you’ll be taken back to the last page you were on. You can also complete the Part 2 tasks when it is convenient for you – you don’t need to do this on the same day as the questionnaires.

8. Is there a reward for taking part?

Unfortunately, we are not able to provide rewards for everyone who takes part. However, all children will be entered into a prize draw for the chance to win book vouchers! We have one £50 voucher to give away, two £20 vouchers, and ten £10 vouchers.

9. Do we have to live in the UK to take part?

No! While the study is based in the UK, you can take part regardless of which country you live in

About Interoception and Eating Disorders

1. I can’t feel anything happening in my body. Is there something wrong with me?

No! A lot of people find it hard to feel the sensations from their body. While some studies have suggested that interoception may be related to lots of psychological factors, including mental health problems, there is not enough evidence to suggest that having poor interoception will cause any problems in your life. Other factors, such as our genes, social situation, environment, diet, personality and biological differences (and much more!) affect our health, both physically and mentally. We think that the way these factors interact is the most important, rather than any of these individual factors alone. However, if you are concerned about any health problems, you should talk to your GP.

2. I’m a little concerned about my responses on some of the questionnaires. What should I do?

If you are a parent, the best thing to do if you have any physical or mental health concerns is to contact your GP. If your concerns are related to eating disorders specifically, you can contact Beat, which is a UK based Eating Disorder Charity. Their adult helpline number is 0808 801 0677. You can also contact them via email at

If you are a child who has taken part in the study, the best person to talk to first is one of your parents/legal guardians. If for any reason you do not want to talk about a problem with your parents, that is OK. You can contact your doctor, or if your school has a nurse or doctor then you can speak to them. You could also talk to your teacher or another relative who you trust. If you have any specific worries about eating, you can also contact Beat. Beat is a special charity that helps people who have problems with eating, especially people who feel that they eat too much or don’t eat enough. They also help people who feel sad or anxious because they do not like the size or shape of their body. If you would like to speak to them, you can call their Youth line at 0808 801 0711, or you can email them at
