First of all, make sure you are trying to log in at the right place. The TWIST (Wellbeing) log in page is at www.teds.ac.uk/wellbeing, not at the main TEDS web site.
You will only be able to log in if we have asked you to take part in this study, in which case we will have sent you three sets of login details, one for a parent, and one each for the twins. If you have lost any of these, please simply contact us for a reminder.
The twin logins will not be activated until a parent has logged in and completed the on line consent form.
We will not change your login details midway through a study, so if you have been able to log in before then please try again. Type the details carefully without any spaces – it should not matter whether you use lower case or capital letters.
We know that 16 and 18 year olds take a wide range of types of exams, including various vocational qualifications in addition to GCSEs and A-levels. Using paper forms will allow the teenagers to record all types of exam results. This would be more difficult with an on line form, where we would probably have to concentrate just on the most common qualification types.
For many other activities, we have been moving towards on line data collection for several years. This has several advantages, including a reduction in our costs, less impact on the environment through reduced use of paper, and improvements in data accuracy and security.
The findings will be published in scientific journals, and also made available on our web site after the completion of the study. As always, information provided by your family will be kept strictly confidential and anonymous.
When you log in to complete on line activities, your details are encrypted so they are securely transmitted over the internet. All the data that you submit are stored safely in a database on a secure server, which is located in the TEDS office. Only authorized TEDS research staff have access to the data.
All the data provided by your family are strictly confidential; your twins are identified only by a number in the study datasets. The data will be kept for a minimum of 10 years after completion of the TEDS study, as recommended by our funding body the Medical Research Council (MRC). The TEDS data are sometimes shared with other researchers, but only after removing identifying information about the participants. We will not pass your family’s information on to any other organisations. You are free to opt out of the study at any stage without giving a reason; data already collected will be stored anonymously, but no further data will be collected.
It is up to you as a family to decide whether or not to take part. If you do take part you are free to withdraw at any time, without giving a reason. Your decision not to take part in this study will not affect your involvement with TEDS in the future.
