Mixed methods: not without its downside?

Prof Edwin van Teijlingen

Conducting mixed-methods research has become very popular over the past decade especially in the health research field.1-4 This development ties in with the growth in inter-disciplinary and multi-disciplinary research. Many grant applications, PhD project and the resulting papers especially in the health field apply a mixed-methods approach, where in the past a single approach would have dominated.   This interest in combining methods seems to be the case even in the more traditional quantitative field of clinical effectiveness and randomised controlled trials. Whilst I find this development encouraging as a mixed-methods social scientist, it also makes me wonder whether the applicants putting forward a mixed-methods project have thought about the disadvantages or at least the opportunity costs of using such approach.

A mixed-methods approach is ‘simply’ combining two or more research methods to address a research question, i.e. what the label suggests. It is often perceived as the combining of qualitative with quantitative methods, but it can technically also be a mix of quantitative methods or a combination of qualitative methods. The advantage of a mixed-methods approach is that the different methods in the mix address different aspects of the research question and that combining these methods offers a synergetic effect. So what are the possible limitations of or barriers to mixed-methods research?

First, using a mixed-methods approach means you need an understanding of two different philosophies and how to bring the findings of these two different methods together.4-6   One requires expertise in two different research approaches, either as individual or in the team as well as someone who can do the combining of the findings. For the latter you really need someone in the team who understand the pragmatic approach commonly used in mixed-methods approaches. Otherwise there is a great risk that the original mixed-methods study will be analysed and reported as two or more separate papers each based on data from one of the methods applied in the mixed-methods study.

Secondly, you can spend your money only once, hence there are opportunity costs. Thus if the maximum grant is £200,000 or £300,000 you can’t spend the full amount on the designing a large-scale quantitative study/survey, as you need to spend a proportion of your money and your attention and time on your qualitative study.

Thirdly, and related the above, both quantitative and qualitative methods have ‘rules’ about sampling and sample-size.5 Just because you have two methods this does not mean you can necessarily do a study with a smaller sample. The sample size calculations will still say you need at least xxx participants. Similarly, although perhaps not so rigidly you need a certain number of interviews or focus groups to do you qualitative study appropriately.

Fourthly, a common mistake seems to be to add a bit of qualitative research to a larger quantitative study, perhaps a bit tokenistic.7 Often it is so obvious in a grant application that the qualitative research is an add-on, an afterthought perhaps from a reviewer in the previous failed grant application.

Finally, not all mixed-methods studies are the same, in fact each mixed-methods study is more or less unique in the way in the way it mixes and matched individual research methods.3 So although mixed-methods may be the best way to address a particular research question, your particular proposed mixed of quantitative and qualitative research might not be the most appropriate to answer the overall research question.8

As with all research methods and research proposals my recommendation is if in doubt go and find an expert for advice.6 If necessary get an expert on your team of researchers to strengthen your application.

Congratulations to FHSS staff on latest KPI publication

Five RiversCongratulations to FHSS Celia Beckett and Jaqui Hewitt-Taylor and colleagues Richard Cross and Pam McConnell based at Five Rivers Child Care, Salisbury. Their first paper describes the exciting process of a Knowledge Transfer Partnership (KTP) project between BU and Five Rivers Child Care which started in 2012 and finished recently in 2015.[1]    The project was established to develop a stepped assessment package that would help to identify the emotional and behavioural needs of children who are looked after to ensure the right services are accessed and to monitor their progress.

 

Congratulations,

Professor Edwin van Teijlingen

Suicide in India: Modelling data

The latest BU research publication used a modelling approach to suicide in India [1].  The paper ‘Time Trend of the Suicide Incidence in India: a Statistical Modelling’ is now online and freely available as it was published in an Open Access journal.  The first author of this paper is BU Visiting Faculty Dr. Brijesh Sathian.  The modelling resulted in some useful predictions of future risk of suicide at a population level, see for example: 10.12691.ajphr-3-5A-17.fig_1

The Future of Welfare Consumerism: Future challenges and opportunities of welfare consumerism in health and social care

Welfare rights and financial advice_mThe rationale for the creation of the welfare state in the post war period was, in large part, because a market approach to welfare had failed. So how can the market and consumerism now be the solution? Despite this philosophical question, for more than two decades welfare consumerism and markets has been and continues to be at the heart of UK health and social care policy. This presents many challenges and opportunities for practitioners, policymakers and researchers alike – particularly concerning older people. Older people are the largest ‘customer’ of welfare services, thus any welfare policy has major ramifications for us all in later life. But what are the important issues? The important issues are basic, but at the same time complex. There is not one welfare market, and with older people not a homogenous group, there are different types and cohorts of consumers.

The basic issue is simple. It is perhaps not comfortable to label welfare as a commodity. A commodity implies a good or service that we purchase to suit a desire. Yet, rarely does welfare satisfy a desire. On the other hand, we access welfare provision because we have a need. Indeed, it is a commodity and market unlike mainstream markets. Whereas mainstream consumers can use their ‘invisible hand’ to navigate markets and access the type or brand of tea, coffee, tablet or laptop that they like, the need to access welfare is characterised by significant information asymmetries, and often complex, vulnerable and emotional circumstances.

Considering these relative complexities, we know remarkably little about how older people act in welfare markets. Although the welfare consumer might have little in common with the mainstream consumer, nevertheless consumer theory provides a platform to outline the more complex challenges for future research and policy.

Implicit in using markets as a means to allocate resources is that consumers are informed and make good quality choices. This in turn requires us to focus on how older welfare consumers become informed – are they adequately informed? Do they seek impartial and independent information and advice (I&A)? How do they act on and use I&A? How can we ensure that I&A services are funded properly and have adequate coverage? These are just some of the broader future challenges and questions that must be addressed.

These are challenges for both health and social care, where the consumerist landscape created by individual budgets and direct payments, first trail blazed in social care (and mostly lobbied for by younger groups), is now being introduced for increasing numbers of older people with chronic and longer term health conditions. Choices of provider and care package/pathway are now and will increasingly be the norm in health and social care.

In addition, my own on-going doctoral study with FirstStop, a third sector provider of information and advice on housing and care issues in later life, acts to highlight another under looked area – housing. Housing may have a longer association with markets and consumerism, yet it is nevertheless a central pillar of welfare. And for good reason – the appropriateness of housing (e.g. preventing falls and fractures in the home as the stereotypical and archetypal example) in later life can be a key determinant of health and wellbeing. In other words, appropriate housing can reduce the likelihood that an older person needs to access health services and social care.

This final point should also chime with the fiscally minded – informed older welfare consumers, through accessing good quality I&A equates to older people making more informed choices about welfare and enables independence. By implication, this means less dependency on welfare – something which, as consumers who will all grow old one day, should be desirable to us all.

 

Congratulations new publication Dr. Pramod Regmi in FHSS

Asia Pac J PH 2015Asian-Pacific Journal of Public Health published an editorial with Dr. Pramod Regmi as its first author.  The editorial ‘Importance of Health and Social Care Research into Gender and Sexual Minority Populations in Nepal.’  The authors argue that despite progressive legislative developments and increased visibility of sexual and gender minority populations in the general population, mass media often report that this population face a wide range of discrimination and inequalities. LGBT (lesbian, gay, and bisexual, and transgender) populations have not been considered as priority research populations in Nepal.

Open Access publishing does not have to be expensive!

Nepal J Epid Open AccessAs it is Open Access Week I would like to clarify one of the Open Access publishing myths.  One of the common replies I receive from academics colleagues when raising Open Access publishing is that it is (too) expensive. This is, of course, true for many academic journals, but not all are expensive.  Some don’t even charge a processing fee at all.  Infamously, The Lancet Global Health charges an article processing fee of US $4750 upon acceptance of submitted research articles.  More moderately priced scientific journals still charge anything up to about £1,500 per article.

Open-Access-logoAcademic publishing has been big business for decades, and Open Access has rapidly become part of that business.  While traditional book and magazine publishers struggle to stay afloat, research publishing houses have typical profit margins of nearly 40%, according CBCNEWS who quote Vincent Larivière from the University of Montreal’s School of Library & Information Science.

At the same time we see a sharp increase in so-called Predatory Publishers who have set up business for the sole reason to make money from Open Access publishing.  They have not established or taken over academic journal for the greater good of the discipline or the dissemination of research findings to the widest possible audience.  Unscrupulous publishers jump on the Open-Access bandwagon BU librarian Jean Harris recently shared an interesting article about Predatory Publishers (click here to read this!).

J Asian MidwHowever, there are other format of Open Access. One of our more recent papers on research ethics was published in the Nepal Journal of Epidemiology which is an online Open Access journal that does not charge authors for publishing!  Also the Journal of Asian Midwives, where FHSS PhD student Preeti Mahato recently had her article accepted, is hosted in Pakistan by Aga Khan University through its institutional repository eCommons.  Publishing in this Open Access online journal is also free of charge.  In other words, Open Access publishing does not have to be expensive!

Paper ahead of its time?

Presentation1Sometimes my co-authors and I wonder why a particular paper get more cited after a few years of publication.  Is is because the paper and the research were are ahead of their time?  Or is there simply a lag time between publication and other researchers publishing in the field finding your paper (or stumbling upon it perhaps)?

Take for example the following paper published in 2006 when I was still based in the Department of Public Health at the University of Aberdeen: Promoting physical activity in primary care settings: Health visitors’ and practice nurses’ views and experiences in  the Journal of Advanced Nursing.[1]

 

Published in 2006 our paper was first cited in Scopus in 2007 (just once),three time in the following year (2008), five times in 2009 and then just a few times per year until this year. In 2015 we have six citations already and the year is not even finished.

We really wonder what lies behind that increased popularity of this 2006 paper.
