On the challenges of ‘doing research’


As a clinician and an educator I need to be aware of, and ‘do’ research. It’s not easy, even when I’m enrolled in a PhD programme! The problem is that so much ‘research’ is not finding out new stuff, it’s gathering existing information into a format that allows for ‘gaps’ in knowledge to be identified and then prioritised. And this isn’t sexy, isn’t visible, doesn’t result in publications, and is often undervalued. A bit like teaching/educating itself!

I don’t know what it’s like in the rest of the world, but here in NZ there are an awful lot of hoops to jump through to even begin collecting data, and this is pretty off-putting. And much of our research has to be based on short-term, fixed end-point research that can tie into the duration of a funding contract. With the thrust for research to be able to directly contribute to something pragmatic, the emphasis isn’t on philosophical or even basic science research, it’s on ‘what is happening now and what can be done about it’. Short, sharp, and applied.

So all the background, really integral parts of research are essentially invisible.

In putting together a PhD proposal, I feel like I’m breaking some new ground. And a whole lot of what I’m doing just isn’t going to be visible in my completed thesis – yet it’s incredibly important. I work primarily amongst scientists who like the hypothetico-deductive model – and I’m certainly not against that in any way. I just think there is a whole lot that happens before a hypothesis can be generated that is absolutely essential, but ignored. And this isn’t easy for scientists of the H-D persuasion. What do I mean?

Well – where did any hypothesis come from?

If we’re honest, it probably came from some sort of observation where someone saw a pattern or phenomenon that was ‘interesting’. It had to be more than a single occurrence because that could just be a ‘blip’ in the time-space continuum (ok, perhaps not there, but a ‘statistical blip’). It only becomes interesting when it happens often enough to be identified as a pattern. Pattern detection itself is influenced by past learning and models, or to bring the analogy back to research, to theory or past research. But it’s not entirely from past learning – new patterns are detected as people spend time immersed in data (otherwise known as ‘information’).

(it’s only after you’ve spent some time immersed in this picture that you’ll pick up the hidden man!)

The pattern recognition phase is not mentioned once in the H-D scientific method – yet it’s fundamental to original research (technically it generates what is called abductive reasoning, or inference to the best explanation, but more of that in later posts!) And Ethics Committees, and funding agencies seem to have trouble coping with non-H-D studies.

Exploring data to find patterns raises questions. Oh no – questions are messy and inconvenient. Questions like ‘I wonder why…’ – and all the ‘w’ questions (who, what, when, where, why – and how which is a complimentary ‘w’ word in this!) are about thoroughly describing a phenomenon or pattern. It’s only once we have a good description of it, can we then start to think about mechanisms to explain the ‘w’ questions.

But think back to your ‘research methods’ course…

How much time was spent on these topics:

– wondering and pondering

– graphing and describing

– philosophy and history

and how much was on:

– experimental design

– statistical analysis

– qualitative vs quantitative

In other words, I think many therapists may learn ‘techniques’ for research, but not an awful lot about why it needs to be done. And therapists learn a lot about confirmatory data analysis such as hypothesis development and statistical analysis, but not a lot about the messy end of making sense of raw data.

Yet – most of us deal with messy raw data every day. It’s the bread and butter of therapy. What we don’t do is systematically collect that data, then explore it so we can identify patterns.

Let’s think of some examples:

– there ‘seem to be’ a number of people who come to pain management with an erroneous understanding of what ‘pacing’ is (ie pacing equals ‘never allowing my pain to go above a certain level’)

– ‘some people’ attending pain management have trouble limiting their activity level rather than being deactivated

– ‘it looks like’ referrals come at different rates from different specialties

– ‘many’ people attend ‘many’ different pain management programmes, but are referred for more therapy

– people being referred to pain management ‘seem to have a lot of’ assessment but ‘less’ treatment

Each thing inside apostrophes is an unquantified phenomenon, and an opportunity for collecting information, then exploring it. Once the information is explored it’s possible to generate some competing explanations for the phenomenon.

For example, if we can identify that 70% of people with a pain duration of more than 18 months have 8 pain assessments, but 2 pain management programmes, and these people are funded by compensation funders; and that the remaining 30% of people with a pain duration of 18 months have 2 pain assessments, no pain management programmes, and are funded by general health funding, we can start to develop some explanatory hypotheses that can be systematically studied.

But this is messy, ‘nonproductive’ research. It doesn’t come up with ‘answers’. It doesn’t ‘explain’ things – it asks questions. It needs to lead to ‘more research’, it needs continuity of investigation so it doesn’t get dropped, and it is real.

In my PhD study, I’m looking to explore the ways people who cope in the community despite having chronic disease processes achieve important activities in their life despite pain. I’m basing this on the observation (that is supported by limited formal data) that there are more people who report pain and disability than are seeking treatment from pain management. I’m not sure what coping strategies I may find out about. I’m not sure how these people developed their skills. I don’t know whether the skills they use are the same as those developed in formal pain management programmes. I don’t have any hypotheses, I don’t have a control group (because I’m not ‘testing’ anything), I don’t want random sampling because I want to look at the widest range of coping skills there might be, I don’t want to eliminate people because they are ‘using high doses of opiates’ because this might be a coping strategy that works well for some people. And yet I’ve been asked whether I have any and all of these included or excluded in my study.

I’m using grounded theory – but grounded theory isn’t well known in the H-D world. It’s a well-recognised research strategy, but doesn’t adhere to the common precepts of the H-D model.

Part of the appeal of ‘doing research’ for me is not knowing what I may find out. The H-D model deliberately forces a researcher to decide before a study what he or she wants to find out. It’s certainly necessary for learning about ‘reality’ and ‘truth’, but in itself it’s not the only part of ‘doing research’.

This is one of quite a few posts I’ll be writing on science and therapy – keep watching!

Why is it important for therapists? As I said before, therapists work right inside ‘messy’ information all day, everyday. Learning to tolerate and manage this data allows us to notice important phenomenon. Perhaps things that haven’t yet been explored in depth, and that might generate new ideas and priorities for the confirmatory part of research.

If you’re keen on learning about abductive reasoning, I thank Associate Prof Brian Haig at Canterbury University for stimulating my thinking and exposing me to this line of science. Some of his writing includes:

Resolutions anyone?


I’m an atypical body, I make ‘New Year’s Resolutions’ every year – oh, and keep many (not all) of them!

But I was impressed when I clicked on through to Dr Deb’s blog and saw her take on the resolution thing. Her idea?

REALsolutions!

What a great idea!

Keep them simple, keep them ‘do-able’, keep them healthful.

Eat healthy.
Move my body.
Keep life simple.
Pay it forward.
Love openly.
Forgive often.
Appreciate beauty.
Yes, that’s a great list.
I’d only add in that each one of these needs to be operationalised – that is, made real and tangible.
Ask yourself ‘what does it mean to ‘love openly’? to ‘pay it forward’?
How would I know that I’d done this? Achieved this?
Set goals so that you have space to achieve them.  What I mean by this is, if you say ‘I will exercise every day’ you know it won’t work.  You know there will be days when you’re out of town, in a late meeting, ill with the flu or something, and it won’t happen.  Then the ‘rule violation’ effect (or  ‘what the hell’ effect!) will come on in, and it’s the beginning of the downhill slide… So what about setting a goal to ‘exercise five days out of seven’ – and on the two ‘off’ days, do something else!
Set goals then enjoy the results.  So often we set goals, achieve them, then immediately move onto the next goal without actually appreciating the achievement we have!  So don’t set new goals every week or month or when you’ve completed them – wait a bit, and enjoy the ones you’ve achieved.
Visualise your goals.  In your minds’ eye, see yourself achieving the goals, what does it feel like? who would you tell? what will you be doing as you achieve your goals? what is your next step?  Once you’ve achieved your goal, in your mind’s eye relive the achievement! Feel the joy, the accomplishment, the pride!  Using your visualisation skills to feel the end result provides motivation that just can’t be beaten.
Tell people and write the goals down.  Keep yourself honest, and make sure you’ve got them written down.  Put them up somewhere you can see them – then you’ll remember to take an opportunity to start achieving a goal at unexpected moments.

Be prepared for the unexpected.  Some goals are about grabbing an opportunity while it exists.  Strike while the iron is hot! Enjoy serendipity, or happy accidents.  And have fun with your goals.  Don’t make them all about ‘being good’ – have some zany and wild ones too.

End of my rant for now – and my goals?

One of them is to carry on with my bellydancing, photography, art and sewing.  Another is to take time out.  Another is to get the data collection done on my PhD.  And eat so my diabetes settles down (and I coincidentally lose weight!).  And finally, to allow myself to be ready for social fun when it presents itself.

2008 is a new page in my life – a continuing chapter, and an opportunity.  Woohoo! Bring it on!

Resilience and coping


Resilience is the ability to positively adapt to changing circumstances or challenges. In chronic pain, this can be operationalised as having high pain intensity, with low interference in activites, and little emotional burden (Karoly & Ruehlman, 2006).

Strangely, more people than not are resilient – fewer people seek treatment than those who just ‘get on’ with life.

I wonder what things lead to being able to do this – is it feeling secure in your own self worth, knowing that people love you and accept you and having the ability to ask for and receive help? Is it being able to be flexible about what is important and how goals can be achieved? Studies show that many factors are known to confer an advantage: genetic, neurological, developmental, interpersonal, contextual, spiritual, affective (Freitas & Downey, 1998; Curtis & Cicchetti, 2003), but the relative importance of each factors is not known.

Just how these factors advantage people is reflected in the coping strategies they use consciously or more automatically.

Most of the people we encounter in our practice are those who are having trouble (or at least are asking for help).

We don’t know that much about people who don’t seek help, so we don’t know how they maintain their wellbeing. And it’s only recently that research has been conducted into positive aspects of psychology, with very little attention paid to people experiencing chronic pain.

How would you adapt to the challenge of persistent pain? Would you change your usual approach to your daily life? Would you even know you had to? Would you change your goals? What about things that are important to you? Or things that you really value?

When we work with people, asking them to adopt a new way of approaching activities, there is absolutely no doubt that we often bump up against people’s beliefs about the way things should be done. These are values, things that they hold as important to them. And we have probably all said at one time or another ‘they just don’t seem to be able to [insert strategy here]’.

Are we being respectful of their values? Are we asking people to do things we do? Are we asking people to do things that resilient people do?

I don’t know the answers to this – it’s food for thought (and a fruitful area for a PhD!). And as I ponder this, I’ll keep posting.
