Define a research question

It's important to formulate a focused research question for your academic work. There are different frameworks you can use to help structure your research question. The different frameworks are applicable for different kind of studies.  

  • The PICO framework is suitable for research questions looking at clinical treatments and interventions
  • The PEO framework suitable for qualitative research questions and relates to person, environment and work, for ex. within nursing and occupational therapy

The PICO framework

Use the PICO framework when you are using a clinical research question.
