We asked people we spoke to if they had messages for professionals running cohort studies. Firstly, many wanted to say words of encouragement. Anne said she “really appreciates what you do” and encouraged others to give research teams “support”. Ian said, “Keep up the good work” and Alan Z praised his study team: “you’re doing a really brilliant job”.
People we spoke to also had suggestions for ways cohort studies could be improved for participants. This included ideas about how researchers could raise more interest from potential participants or support current participants. Their main messages were:
- Maintain communication and provide more feedback to participants;
Good communication from researchers was appreciated by many of the people we talked to, and they encouraged researchers to continue doing this or to do more of it. Linda said the researchers kept in touch and this helped her feel she was still involved.
A key message from many people was for study staff to provide more feedback on study findings, what the information is going to be used for, and updates on what the study is planning to do next.
Many people thought a yearly newsletter, which could be included in the annual birthday or Christmas card for some birth cohort participants, and with a website link for more information, would be a good way to provide this. Malcolm thought updates of a few sentences or pages long would be sufficient. For studies which give participants individual test results, some people like Nadera felt there needed to be more information to help them make sense of the results.
Some people were positive about researchers using different ways to communicate (post, telephone, online). Malcolm and Isobel highlighted that it’s also important to cater for those who don’t or can’t use the internet.
There have been some ‘get-togethers’ for participants in birth cohort studies, and those who attended were usually very positive about these events. Barbara and Jennifer had enjoyed the meet-ups and would have liked more of them earlier in the birth cohort study. Barbara explained, “It’s a lonely thing because you’re just doing your little bit. Because you’re only just filling in these forms now and then, you don’t know what’s happening.” Jade, whose cohort study activities had not involved meeting other twins, thought meet-ups would be fun.
- Recognise that participants and potential participants are important, and work with them;
Some people we spoke to were keen to give their feedback on individual studies to study staff. Some were in roles as
public-patient involvement (PPI) representatives and advisers. Mr S became a ‘Dad’s Champion’ for a birth cohort that his children were enrolled in, and this included giving feedback on proposed sub-studies and running a stall to encourage more fathers to join the study. Nadera thought it was important that researchers listened to participants and people who might take part in their studies. She attended meetings “to speak for the community.”
- Ensure study documents are written clearly and, if possible, provide them in multiple languages;
In general, people said it was important to keep language and terminology simple. Emily also wanted researchers to carefully proofread their own study documents, as she had found many typos. Nadera encouraged researchers to provide study documents in multiple languages for people who don’t have English as their first language.
Some people talked about certain questions on questionnaires being poorly phrased. It could also be unclear why the researchers were asking certain things, and this was all the more important for personal and sensitive topics.
- Make sure people know their rights about being in a study and offer opportunities to talk about any concerns;
Taking part in a cohort study is a choice, and it is not something anyone should feel pressured to do or continue doing. Luke suggested offering people an opportunity to discuss why they may want to leave a study to see if it can be remedied rather than saying that they can leave at any point.
Those who had been enrolled in a study as a child often felt that this topic needed to be revisited at a later date when the person was older. It is important to make sure they are re-informed, re-consented and given the option to opt out. Some birth cohort participants we talked to had been unaware for many years that they were taking part in the study because the information had not been passed on from their parents. This left some feeling unsure about the purpose of the study and what their information was going to be used for.
At the same time as not putting pressure on people to participate, the people we spoke to encouraged researchers to educate potential and current participants on the benefits that cohort studies can bring to the public.
