Thank you for your interest in this study. Please read the participant information below and answer the screening questions, which will enable us to determine your eligibility for the study. If eligible, the researchers will send you the full survey for completion.

You are invited to participate in a study that examines the nature of fatigue, factors that influence fatigue and how fatigue affects functional everyday outcomes. The research is being conducted by Dr Cynthia Honan and Dr Jane O’Brien. Ms Samantha Findlater will be assisting with the study in partial completion of an Honours  degree within the College of Health and Medicine.

Purpose of the study
The purpose of this study is to investigate the relationship between subjectively experienced fatigue and functional outcomes (e.g., everyday social functioning, social participation, employment, quality of life) in people with chronic fatigue syndrome (CFS) when compared to healthy individuals. Factors that may influence this relationship including sleep, illness severity, social support, diet and lifestyle, and cognitive skills, will also be investigated.

What does my participation involve?
If you wish to take part in this study, you will be asked some initial screening questions (below) aimed at identifying whether you are suitable to participate. If you are deemed suitable, you will be emailed a unique participant number and a weblink to complete the full survey online. The survey will contain a series of questionnaires related to your: (1) general background; (2) CFS symptoms (if you have CFS); (3) diet; (4) alcohol use; (5) symptoms of depression; (6) experience of fatigue; (7) experience of daytime sleepiness; (8) sleep quality; (9) perceived thinking difficulties; (10) social functioning; (11) social support; and (12) quality of life and social participation. It is recommended that completion of the survey in the one sitting, although breaks can be taken when required. It is estimated that the survey will take 40 to 70 minutes to complete. If you feel that you would like to complete the survey over a longer period of time, we can post the survey to you.

We will also ask you for permission to contact a family member or friend (this is optional) to complete a short survey about your social functioning and integration as a result of your illness or condition. A link will be provided at the end of the (full) survey which can be emailed directly to your family or friend for completion.

The current research is intended to improve our understanding of the nature of fatigue and the link that fatigue may have with various functional outcomes in CFS. Whilst the benefits of participating in this research may not be of direct benefit to you, your participation will provide us with some invaluable information that will assist other people with CFS, researchers, and clinicians to further understand in particular the types of fatigue-related factors which are most relevant in predicting everyday functioning. Such an understanding is important as it may lead to more effective rehabilitative treatment programs for those who experience difficulties with fatigue. Note that your individual results from the questionnaires will not be available.

There will be no payment to participants of this study.
You are encouraged to discuss your participation with a family member, carer, or doctor prior to consenting to participate in this research. Where possible (or if asked by the researchers), please have a family member or carer present to witness your consent prior to completing the survey. Acknowledgement of the presence of a witness can be provided in the online survey link or by having your witness co-sign the included consent form (if receiving a hard-copy of the survey in the mail).
