This questionnaire is for completion by the study young person. To log in you will need the username and password we recently sent you in the post. If you do not have your username and password please email

The data you provide will be available to approved researchers across the world and will help in answering important questions on human development, health and disease.

Please remember that your answers to all these questions are confidential and will be processed using a unique ID number. All your personal details will be removed by Children of the 90s staff and researchers will not be able to link your answers back to you. Your data will only be shared with approved researchers for research that has been approved by Children of the 90s.

Some questions may seem very similar to each other. This is because the combination of answers gives a clearer picture than one single answer. There may be questions that seem a bit strange and are not applicable to you because they are about specific feelings or problems. We would be very grateful if you would try to answer all the questions but we understand if there are questions that you either prefer not to answer or are unable to answer. Please just leave these questions blank. There are no right or wrong answers.

If you need help completing this questionnaire, please contact us and we will be happy to make the necessary arrangements. If you do not wish to complete this questionnaire please let us know by emailing with your name and date of birth and No to annual questionnaire 2016 in the subject line. We will then know not to send you any more reminders.

Thank you for taking the time to complete this questionnaire. To say thanks for taking part, we’ll send you a £10 shopping voucher which you can spend online or on the high street.

A list of organisations that offer support on some of the issues raised in this questionnaire is available on our Helplines sheet (PDF, 193kB).
