Refining the research question
What should a research question be?
Burns and Grove (2011) outline that a research question is clear, interrogative and relevant, therefore pertaining to the research topic that you have chosen. It must also be focused, feasible and answerable with a research design within the time frame and resources that you have available.
It should contain the specific variables that you intend to study, as well as the sample (O’Brien and DeSisto 2013). It must also be ethical.
Another useful way to refine your research can be with the use of mnemonics, such as PICO (Smith 2008), which stands for:
- Population or problem
- Intervention or independent variable
You can further develop this by adding an ‘M’ for ‘Methodology’ to make the mnemonic PICOM (Beitz 2006).
If you think back to the previous step in which we read the systematic review by Smith and Pell (2003), it was evident that there was a lack of randomised controlled trials guided by appropriate research questions investigating the use of parachutes to prevent death and trauma. You may, therefore, consider the M in this example to be randomised controlled trials.
This mnemonic can also include ‘T’ for ‘Time’ to make the mnemonic PICOT (Thabane et al. 2009).
