Cohort Studies

Messages to research teams running cohort studies

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”.

Keith would like to say thank you to the research teams of both cohort studies he took part in. His experience has been very positive.

I don’t think there was anything I would say to improve practice but what I would say is thank you because they’ve always dealt with me with the utmost civility and friendliness and, and information has been good and given and if they continue in that way as they have with me then it can only be, you know, a contributing factor to the success of the research. No, I’m very positive about the whole experience in both cases.

Ian feels the way he has been treated while taking part in the cohort study has been fantastic. He says, “keep the good work going”.

Keep the good work going, yeah. You know, I like the way that I’ve been respected, and I like the way that I’ve been handled and spoken to.

But I think the medical profession, the way they’ve been with me, has been fantastic, and if they can be like that with everyone then they’ve got a great chance in the future of being successful.

Alan Z believes a lot of people will benefit from cohort study research, and he and others appreciate the team’s work.

Well, I think you’re doing, you know, really brilliant job and I’m sure lots and lots of people would benefit from it and we all appreciate your research and endeavours and the outcome of your research, yeah. I think it’s, you know, as I say, a jolly good thing and I can’t see anybody’s who’s open minded, not volunteering to do it. It’s like, you know, volunteering to give blood etc. It’s just one of these things you feel you want to do.

Yes, yes. I mean it’s-. Whenever I go for my six monthly- not check-up but research, if there’s anything that’s cropped up or any problems that have cropped up, issues things I might think I don’t understand, I make sure they’re asked at the session, at the research session. And I haven’t said this before, but it takes the best part of a day. It’s probably, I don’t know, four or five hours. And it also helps pass the time if one can have a discussion about my own PMA or just, you know, MND in general. And the doctors are very enthusiastic, and I have asked them on occasion why they carry on working on a disease which is incurable and debilitating. And it seems to be a, it seems to me to be quite a negative- not negative, that’s the wrong word but soul-destroying illness to be involved with, because in effect they can’t do anything. All they can do is diagnose you and even that can take six months, and that’s partly why the [biomarking] study is hopefully going to provide some quicker means of diagnosing MND. Because the quicker the disease is diagnosed, the quicker people can be put onto riluzole, which is the only drug can help people with MND.

 
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;
Recognise that participants and potential participants are important, and work with them;
Ensure study documents are written clearly and provide them in multiple languages; and
Make sure people know their rights about being in a study and offer opportunities to talk about any concerns.
 
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.

Nadera suggests giving people more explanation when they get their individual test results.

And do you know the results of these tests?

Yes with-, without explanation though…

Okay.

…which I would say would, they should do. But they’re, “Everything is normal”. ‘Yeah, okay, normal for them but which norm-?’ They had graphs as well, so I went back myself, researched it, looked up and what it means, my subcutaneous fat, there’s my visceral fat plus my bone density, yeah.

The feedback is the bigger thing that, as I say, again and maybe more written stuff I understand will be hard for the admin to do too much paperwork but just copy some of the end results maybe in a few lines in a summary, drop it back to the parents, drop it back.

Rafi and Iram suggest that as well as collecting information from participants they need to provide the study answers.

Rafi: She said, like the sample they took, so that was good but it’s-, they have to come back as well, so this is something that may make it better and this is other things as well. You know, if they’re doing something, so they have to come back with the answer or solution as well.

Iram: How again? Like how they came, for example when they’d taken it [the sample], we didn’t get a response back. This means they should do everything properly in doing so. If they ask a question, then the answer would be right”.

So that was just…

Rafi: Not just asking; there should be answers as well then for that.

 
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.

Malcolm feels it is polite to give some general feedback on the study and that a short summary every year would be well-received.

Yeah if you’re volunteering yourself and your information for a study, you know, it’s only, it’s only sort of, well it’s nice to be able to be informed about it. It’s polite, isn’t it, to give some feedback other than just results on your own physical test.

Just little updates not in-depth just a few lines, a few pages of report maybe or a page of a report, an update, a few bullet points. It’s quite easy to produce a report in an easier understanding format that anybody can understand.

Jennifer recommends giving participants more detailed feedback of study results.

Yeah, you get this envelope and you open it and you start reading, you think, ‘Oh, this going to be interesting.’ Then you think, ‘Oh, they’re not telling me very much.’

Okay.

And I get that, and I wonder what they’re getting, like, I just sort of said, I wonder what they’re getting out of it because they’re not telling us very much.

 
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”.

And then last year I did participate in a focus group. It was about this time last year which was a group and there-, they were really discussing almost the next stage and they were planning again, whether the funding’s there to do things like MRI scans on people and how we would react to that because I think a lot of people, things that are more invasive, I think some people would be quite reluctant to participate. So that was quite interesting on how we felt about it and how they could actually, I suppose sell it for want of a better word to us.

And what were your feelings about it?

Well I, you know, I, I’m, actually I was-, interestingly a lot of us felt very nervous about the thought of having an MRI scan just for, for research purposes. It’s one thing having something like that if you need it but they were very reassuring and I think quite a few of us who might have been reluctant but came away from that, I mean it was just a couple of hours and the lunch I think, just, you know, came away feeling quite confident and I think we, you know, would participate.

My message would be that stay connected to average people, you know, you, you can learn a lot from them or they can have a, a big input on your studies. And especially, you know, living healthy and like the problem I just told you about seem small but, you know, about litter in the street but if you look at it, it has an impact on our children. So if you stay connected with average people, find out about, you know, different issues or problems that they’re facing, it can direct you towards your research or find a solution to various problems that communities are facing that has an impact on their health and emotional wellbeing.

Nadera thinks the research team should include people with a mixture of abilities and experiences who understand why the research is important to participants.

I think some of the people who do do the research should be coming from the family categories as well.

In what way?

In like a lot of people are youngster that are sitting there doing the research, but they don’t know what it actually happening. It would be nice to have a mixture of all abilities. Have some mothers on the research team as well; have some fathers; have some young people there as well. Does that make sense? Rather than making a research team out of just professionals/students or you are good in that? Develop the skills in them and they will be more empathy, understanding the research as well, understanding the person, so they will realise why they come out rather than just say, ‘Oh collecting data, like ten, twenty, forty, fifty people, that’s the answer, that’s it.’

So do you think there should be people from the community involved in…

Yes.

…actually running the research?

As well, yeah.

But again, they should be upskilled. I’m not saying just pick anybody up [laughs]. Train them. Give them the training to understand [laughs].

It’s never too early to involve your participants or your future participants in what you are going to do, not what you’ve done or what you want to do but actually to involve them in the things that matters to them, to hear what they are.

Through an advisory panel like the one with you…?

I would not want that consultation and that dialogue to be reduced to a forum or a kind of round table kind of committee hosted every, you know, couple of times a year. I think that they could be much more sophisticated than that.

And, so perhaps through e-mail consultation or letters going out you mean?

We have, you know, as this group kind of has demonstrated, enormous technological capacity to improve the way in which we both design and conduct our studies and there, I think there needs to be more put into how we agree what studies we should do. And that’s something that the studies can’t do on their own. It’s something that the research councils and other funders need to think very carefully about because at the moment it’s a sort of, it’s all done through a kind of closed bidding process with expert panels and I think it could be a lot more involvement of participants and the participants who are ultimately the ones that are providing the data for this research to be done.

 
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.

Mr S thinks some questions in questionnaires are personal and people may be reluctant to answer them. He encourages researchers to carefully phrase their questions and explain why they want to know.

Yeah, I’d say obviously certain questions that they do ask are quite personal, you know, some people are a bit reluctant to answer those, you know?

What kind of questions would that be?

You know, for example, you know, like you were talking about people’s private lives and all that. Certain people, I’m not saying everybody, but some people are a bit reluctant to talk about their private life and everything like that, you see, so they might want it to be, you know, explained in a different way for example.

So that’s where, you know, I think [cohort study name] might have to look into and think, “We may have to look at the way we’ve worded stuff “or like “the way this questionnaire is it could be that these questions could be a bit sensitive to the patient”, for example, and “they might not want to answer that - so we might have to look at the wording of that, the structure of that” and then obviously that might help, on a positive note improve the information. I don’t know what the results but I’m just thinking that it’s, some people are quite open, and they’ll just answer it, like myself. But some people are a bit reluctant because they think even though it’s all data protection and everything’s private and confidential - still they have that in the back of their mind, ‘do I really want to answer that question?’ Do you know what I mean?

Yeah.

But then again, I’ve seen on the questionnaires, it says, if you don’t want to say, prefer not to say, you don’t have to say but then it says that if you, I think on one of the questionnaires, it was saying that if you don’t answer them then we might not get an accurate result.

Okay.

You know what I mean, so? It like contradicts itself in a sense, where you’re saying, “Look, okay, don’t answer it, but then if you don’t answer it, if you prefer not to say, you’re not giving it here, like if you don’t answer it, yes or no for example then, you know, the results are not going to be-,” you know.

So, there’s like a little bit of pressure to…?

Pressure, yeah, yeah, yeah, I think yeah. So, I think that they could look into that and change that particular aspect.

So, can you think of an example of a question that you think may be uncomfortable answering?

I think, for example, like their religious belief. I think some people are a bit reluctant to talk about that, might have a bit of an aspect of, ‘Why do I need to answer that question?’ you know what I mean? I’m quite open about that but I think, some people think if I answer that question, ‘Oh look, is that going to differentiate me in any way’, and I think another question maybe, ‘What’s your origin?’ I think sometimes they may be thinking, if I mention that they might think, ‘oh, just targeting certain areas’. So even though I’ve always answered it myself, I’m just saying that some people may feel a bit uncomfortable with that. Or even talking about whether or not the family members have had a certain condition, you know, or an illness.

But I think, ‘Why are you asking that?’ is the thing. I think that’s the most important thing, I think if someone knows why they’re asking it then they’re going to be more comfortable giving an answer. But if you’re just saying, ‘Oh look, we want to know if you’re this, this and this?’ and I’m thinking, ‘Well that’s quite a delicate or sensitive matter, why do you want to know that?’ And they’re obviously having to think about, ‘Well, why are they asking me these questions?’ I think, like you said, if they’re given information like prior, that this is what we need it for then I think the person will be more assured.

Emily suggests online questionnaires should have the option to give feedback about the questions asked.

Okay so every survey should end with, "What question should we have asked but didn’t?" And every question should have, you know, confidence in the answer or even just a like and a dislike button because the dislike button you could then when you receive it, if they’ve left their email and it’s not totally confidential, you could go back to them and say, “Here’s the question you disliked, what did you dislike about it?” “Well, the question wasn’t clear, and the options didn’t match anything in my lifestyle so my confidence in it was zero, so I just thought you ought to know”.

But as a parent governor you’re presented with various like, for example, like memos or like maybe leaflets that they’ll wanna send to other parents and they ask us to go over it. “Is the language understandable?” you know, “Is it friendly, average people can read it?” or, “What do you think of the questions? Are they too invasive? Would people be pushed off by it?” So we usually as parent governors give them feedback about, you know, yes the terminology is too medical depending on who like, I remember one of the PhD students she wrote for her PhD she wrote like a like I think it’s a healthy, healthy living or life, changes for life or something like one of those.

Yeah, the questionnaire that she did was too medical so we said to her like average people won’t, you know, people that speak English as a second language they won’t understand the terminology so simplify it a bit or for this word instead of using this word this is another word that you can use.

Asking it in simple terms.

Exactly

It’s in simple terms because different people are different levels in their education and understanding.

Exactly.

So keeping it simple you’ll get most people understanding what you’re trying to say.

 
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.

Malcolm suggests giving people soundbites of information so that they become interested in the research and want to participate.

The main point is to explain that benefits I think to both of them, to them and to-, to the research that they’ll be contributing to. Or to the programme, the project that they’ll be contributing to but also benefits to them. I think- I think that’s the only way you can get people to participate. I think you can’t force people, you just have to raise their interest level, so I think you- you can pick out issues that would be informative to them from the- from the tests that you’re doing from the project that you’re doing and say, “Would you like this to happen, would you like to take part in this because-?” You know, fixate on something that maybe would interest them rather than turn them off. So maybe a lot of information is good to certain people but small snippets of information is good for others, you know, sound bites. I think that’s the only way you can get people interested is by just giving them more information.

Lucy says researchers need to be flexible about the way they collect data to make it comfortable for participants and ensure participants know they can opt out if they want to.

And just make sure they understand their rights, I suppose, in relation to it. That this is not required, that it’s not something they have to submit to for their own kind of-, in the same way that if you were unwell and you needed to have medication or blood tests, you know, there’s limited choice in that situation, there’s still choice but it’s, you know, that it’s in your best interests to do it. Whereas in this situation, if there’s no direct, obvious benefit from participating, I think it needs to be really clear that they don’t have to keep doing it if they don’t want to, or maybe there are ways that you can kind of be more flexible about how you approach things, to make it more comfortable for them. So, in my experience, maybe, maybe if somebody had said to me, “Would you just prefer two female researchers?”, I maybe would have said, “Yes”, as a teenager, I might not of, I might of just been too embarrassed and been like, “No, no, it’s fine”. But giving options and choices and making sure they understand that this is not required from them, yeah.

 
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.

And I would love to have, I would love them to have a safe and secure and developed place to live. I don’t want them to feel that we are living in a, you know, ‘deprived’ is a very sad word. Deprived is a very harsh word to say, I think. ‘Why we are deprived?’ because we live in England, you know and, and people say deprived area. It hurts me when people say, “You’re from [city], it’s a deprived area”. “You’re from [city], it’s a backward area”. It is not. I want everybody to know that it is a beautiful place to live. People and community around me is amazing and there’s some fantastic research going on. [study name] is doing amazing job and it is bringing change in lots of people’s life. As I mentioned, if you would have met me three or four years ago, I was completely different person and I grow as a person because I was participating into something which I felt is needed.

Oh I’d say, I’d actually say keep up the good work and as I say I just hope with all the sort of economic uncertainty that they’re able to get funding to continue because I think, you know, with more of us living longer I think this stage of our lives the research is almost more important than some of the earlier things.

And do you think that sort of, you know, putting money into a long term cohorts study has benefits over just funding a short term study?

I think so because I think there’s a lot of preventative work that can be done. I mean they-, with this study thinking particularly about the, the sort of dementia aspect, I mean they will be able to look at us from the age of 50 and, you know, when they see who has dementia, who gets dementia, Alzheimer’s; there may be trends. There may be things that they can spot that about when we were 50, you know, maybe something completely, at the moment seem completely irrelevant to, you know, the increase of dementia but they may be able to see trends and see, you know, certain things that, you know, conditions at 50 were going to affect the likelihood of us getting Alzheimer’s and dementia and be able to correct, be able to deal with this for subsequent generations.
