Ethics and Engagement

Variable Response
Participant engagement
Is there participant representation in the governance of the cohort? Yes
Do existing mechanisms for consulting/involving participants exist? Yes
If so, does this happen on an ongoing or an ad hoc basis? Ongoing. There are two members of the public who sit on the study management team, every study using data from the study are assessed to ensure that they have included adequate public and/or patient involvement in the development of the methods, and the main governance of the study is via a Public Delivery Board which is made up of a majority of lay members.
Is there an ethics advisory or ELSI group within the cohort governance? Not within the governance structures of the study itself (the Scientific Steering Committee and the Public Delivery Board). The study received ethical approval from the Wales REC 3 committee. We report to this committee on a yearly basis and all changes to the study methodology (e.g. the insertion of new questionnaires) are submitted to the committee a substantial amendments to our ethical approval.
Does the cohort include participants who lack capacity? No
Is there a process in place for participants who lose capacity? Yes

Do procedures exist for the disclosure of incidental findings? No
Do procedures exist for the disclosure of clinically relevant information identified as a direct focus of the study? (e.g. a diagnosis of dementia) No
How was the cohort recruited (NHS or not, primary or secondary care)? Project team members for HealthWise Wales are currently providing information and raising awareness about the project through media platforms, at various events with the general population (including events such as Cardiff Food and Drink Festival, and the Royal Welsh Show following invited presentations), and at various NHS sites such as GP surgeries, outpatient departments and antenatal clinics. There is also a proposal for active face-to-face recruitment that is currently being assessed by the ethics committee.
Does the study involve ongoing connections with participants' own doctors (e.g. GPs)? No
Consent and recontact
Is there consent for recontact? Yes
If so, under what conditions? "When participants register for HealthWise Wales, part of the informed consent for the project is recontact. When registering, participants give their consent to be contacted every 6 months or so by the HealthWise Wales research team to complete new questionnaires, and to be contacted by the research team about other studies that participants might be interested in.
