This paper is one
of a series of short
papers on aspectsof research by
Linda Shields and
Alison Twycross
The first question asked by any researcher with a new
topic to study is: What sort of research should I use?
Reference to the literature can be confusing: so much
research has been done, so many questions asked andsometimes answered, and so many conclusions have
been drawn that it can be difficult to sort out one research
technique from another. The decision most beginners to
research find taxing is: Should I use quantitative or
qualitative methods?
At the most basic level, quantitative research methods
are used when something needs to be measured, while
qualitative methods are used when a question needs to
be described and investigated in some depth. Often, the
two methods are used in tandem to provide
measurements for comparison and evaluation and togive an in-depth explanation of the meaning of an idea.
Quantitative research
The words themselves hold the clues. Quantitative
research includes so-called benchtop science (where
experimental tests are carried out), drug trials (where the
effects of drugs are measured), epidemiology (where rates
of illnesses in populations are calculated), intervention
studies (where one technique is used and its effects
compared with another), and so on. Quantitative research
usually contains numbers, proportions and statistics, and
is invaluable for measuring peoples attitudes, their
emotional and behavioural states and their ways of
thinking.
In one section of a study on child care in hospitals, I
asked a group of parents to give a yes or no response
to a range of questions on their attitudes to paediatric
hospital care (Shields 1999). I then measured the
number of yes answers and compared them with
responses from nurses and doctors to the same
questions. The study showed differences in attitudebetween parents and staff that could have affected
communication between them and influenced the
delivery of care. In another example, a researcher in
Iceland measured the most important needs of parents
during their childrens admission to hospital and found
that they rated emotional needs as more important than
physical requirements, such as rest and food(Kristjansdttir 1995).
Qualitative research
Qualitative methods are used when the meaning of
something needs to be found. Exploring the question:
Who owns a child in hospital? (Shields et al 2003), or
examining the meaning of an experience, illness, or
condition, for example, of what it means to be a mother
whose child has died (Laakso and Paunonen-Ilmonen
2001), are all forms of qualitative research. Qualitative
research usually has no measurements or statistics butuses words, descriptions and quotes to explore meaning.
It can even use arts techniques, such as dance (Picard
2000).
The question to ask when planning a research project,
therefore, is: Do I want to count or measure something,
or do I want to find the meaning of something, and
describe it? Which comes first? This is sometimes a
chicken-and-egg question but if no one has investigated
the topic before, qualitative research is used first to try
to tease out ideas, which can then be turned into
questions that can be tested quantitatively PN
