    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
