Participant Information Sheet


If you are 16 years or older, have a diagnosis of cystic fibrosis (CF) and are under the care of a clinical CF team we would like to invite you to complete our online survey, which is an educational project contributing to Lauren Clayton’s PhD thesis. Before you decide whether you want to be involved it is important you understand why the research is being done and what it would involve for you.


Why are we doing this survey?

Traditionally it has been believed that people with CF lose an increased amount of salt through sweat, especially during exercise or when in a hot environment. Despite exercise being an important part of clinical care for people with CF, there is a lack of clear guidelines on salt supplementation or hydration when exercising with no exercise-specific guidelines. Similarly, there are no guidelines on salt supplementation or hydration available for during hot weather or exercising in hot environments.

New treatments for CF known as CFTR modulator therapies (e.g Kaftrio/Trikafta®, Symkevi/Symdeko®, Orkambi® and Kalydeco®are now raising even more questions around salt supplementation as current guidelines only consider salt losses prior to the availability of modulator therapies. However, not everyone has access to these modulator therapies, and it is important we understand more about people with and without access to these treatments.

As a group of clinicians and researchers we want to help build the research to develop clearer guidelines.

We need your help to understand your experiences of:

1. Physical activity and exercise behaviours

2. Experiences of symptoms of dehydration and heat-related illness 

3. Current salt intake and use of salt supplements (e.g. tablets etc.) at rest, during exercise, during exposure to hot environments and whilst exercising in hot environments. As well as your current knowledge of salt supplementation and hydration guidelines or recommendations from specialists in your clinical CF care team. 


Am I eligible to take part?

To participate in this survey you must meet the following criteria: 

- Be 16 years or older

- Currently under the care of a clinical CF team

- Have a clinical diagnosis of CF


What will happen to me if I take part?

If you agree to take part you will be asked to complete the online survey about your physical activity and exercise behaviours, your experiences of symptoms that may be linked to dehydration or heat-related illness. You will also be asked questions on your current salt supplementation regime including any salt tablets you take, salt you add to your diet, or any fluid you consume to help increase your salt intake or hydration. We will ask you if you follow any guidelines and what guidelines you follow or whether you get any guidance from specialists in your clinical CF care team. The survey will take you approximately 20 minutes to complete.


Do I have to be involved?

No, not at all. Being involved is completely up to you. You are free to withdraw at any point during the survey by exiting your internet browser. Once you have submitted your response you can no longer withdraw from the study. This is because results submitted will be anonymous and we will not be able to determine which response is yours. 


Will my results be confidential?

Yes, all results will be kept confidential and stored anonymously. Results of the survey will be stored on the JISC software until the study closes. Once the survey has closed, data will be saved securely on the University of Portsmouth's Google Drive. Only members of the research team will have access to the data.

At the end of the study we will publicise this work in the press and in research journals. It will not be possible to identify individuals. You will be able to access study results through a summative report which will be found on the CF Warriors Charity website, This will also be advertised through the CF Warriors Charity social media accounts (Twitter; @CFwarriorsUK or Instagram; cfwarriorsorg). The data may be used to apply for further funding to continue this work.


What if there is a problem?

If you have a query, concern or complaint about any aspect of this study, in the first instance you should contact the researcher(s), if appropriate. As the researcher is a PhD student, there will also be an academic member of staff listed as the supervisor (Dr. Zoe Saynor), whom you can contact with details of the complaint. The contact details for both the researcher and Dr. Saynor are detailed at the bottom of the information sheet.

If your concern or complaint is not resolved by the researcher or their supervisor, you should contact the Head of School:

Professor Richard Thelwell
