|Intervention||Content/what||When||Format||Where||How often||Who should provide this?||Who should receive it?|
|1: Incentives and Rewards for follow-up clinic attendance||
a. Monetary incentive and reward: Financial incentives which participants could choose (e.g. monetary, charitable donation, prefer not to receive). Total incentive cost should not exceed £15, which may be broken down for each visit (i.e. £5 for each visit) that is accrued over time.|
b. Non-monetary (social) reward: Send ‘Thank you’ note after attending each clinic and mention that they are making a difference.
a. Monetary incentive and reward: Inform during and after recruitment/|
b. Non-monetary (social) reward: At the end of a trial
|Trial dependent: written information delivered by post or electronically (i.e. email containing online link for charity/vouchers options)||Participant receives at home||
a. Monetary incentive and reward: On completion of all visits|
b. Non-monetary (social) reward: After each visit
|Trial dependent: trial office/point of contact, health professionals, e.g. clinical specialists||Conditional on behaviour: all participants would have the opportunity to receive the incentive but only those who complete the behaviour would get the reward|
|2: Goal setting for improving questionnaire return||
Set goals that all questionnaires need to be returned. Show an example of the questionnaire and provide an opportunity to work through|
Provide the contact details (and photo) of the point of contact for any queries
During follow-up provide number (%) of other people who completed the questionnaire to encourage further
|During the beginning of the trial likely during the informed consent process.||Trial dependent: verbal, paper based, electronic.||Trial dependent: at trial site or home.||Dependent on the total duration and how many follow-up points in the trial||Trial dependent: by the point of contact, health professional, recruiter or peer from the trial||All participants|
|3: Self-monitoring to improve questionnaire return and clinic attendance||
1. Provide a portable sized loyalty card (indicating date when questionnaire returns or clinic visits due).
2. Provide a personalised planner—as above with dates for clinic visit or questionnaire completions.
On the other side of the card, mention the purpose of the trial and details/photo of the point of contact
Participants will receive a sticker (after completing each activity) to put on the card/planner
|Given timing of questionnaires/clinics will likely depend on date of randomisation, this needs to be delivered post-randomisation||Trial dependent: verbal, paper based, electronic||Trial dependent: at trial site and/or home||During each follow-up (e.g. a week before) send a reminder about self-monitoring||Trial office/point of contact||All participants|
|4: Motivational information to improve questionnaire return and clinic attendance||Motivational information framed as positive reinforcement e.g. end purpose of this research, benefits of being involved, and how others are doing in the trial||Initial recruitment consultation, in the patient information leaflet and throughout the trial during any patient contact||Trial dependent: verbal, paper based, electronic||Trial dependent: at trial site and/or home||Dependent on the trial duration e.g. will be linked to key ‘touch points’ between trial office and participants||Trial office/point of contact||All participants|
|Case studies: Aspirational messages about how other research has changed clinical practice|
|Online forum/peer support to encourage participants throughout the trial period|
