This leaflet tells you about our study investigating how well people remember their use of mobile phones.

Why was the study set up?

To find out how accurately people remember their use of their mobile phone. The results will help us with the findings from a separate study investigating the potential health effects of using a mobile phone.

Why is this study important?

The use of mobile phones is rapidly increasing and their safety is an issue of public concern. Studies assessing the possible risks involved often ask questions about past phone use. We need to know how accurately people remember this if we are to make use of this information.

Who is doing the study?

The study is being organised by the Unit of Epidemiology and Health Services Research at the University of Leeds. Our research team is listed on the back page with our contact address. It is funded by the Department of Health.

What kind of people are we looking for?

We hope that people of all ages and backgrounds will take part. As long as your name appears on a mobile phone bill you are eligible.

I have a pre-paid phone: do you want me to take part?

Yes please. We might have less information from the operators but we do want to include pre-paid phone users.

What does it involve?

About 10 to 15 minutes of your time. We would like you to answer two short questionnaires, one now, the other in 3 or 6 months time. The questionnaire can be completed over the telephone or you can post it back to us in the pre-paid envelope provided.

What will happen to the information?

The information you give will be checked against records of your use provided by the mobile operators. We can only obtain this data with your signed permission. The four mobile phone operators in the UK have agreed to collaborate by providing us information on individuals’ mobile phone use with their written permission.

If I agree what sort of questions will I be asked?

There will be a brief set of questions about yourself and about your mobile phone use. This will include, how often you use your phone and how long the calls are.

How will this information help the research?

Decisions on whether mobile phones may effect your health may be based on studies which ask people about their past use. It is crucial for researchers to know how reliable and valid this information is.

Will the information be kept confidential?

Yes. All the information you provide is entirely confidential. It will not be given to anyone and the data will be destroyed at the end of the study.

Why should I help?

Because we need volunteers to support our project, the results of which will have implications for future epidemiological research into mobile phones. We would really appreciate your involvement and help in our study.

What should I do now?

Please fill in and return the enclosed form indicating whether you would like to answer the questionnaire over the phone or send it back by post.

[If you have picked up this leaflet without the questionnaire, consent form and pre-paid envelope, please contact Roger Parslow at the address on the back of this leaflet].

You will also find a form to sign and return to us giving us permission to look at your records held by the mobile phone operating companies.

If you agree to take part a research interviewer will then contact you.
