P — Population
The group, population or setting you want to study.
E — Exposure
The exposure, experience, condition, situation or phenomenon being explored.
O — Outcome
The effect, experience, perception, behaviour or outcome of interest.

PEO question FAQs
What does PEO stand for?
PEO stands for Population, Exposure and Outcome. It helps turn a broad topic into a more focused research question.
When should I use PEO instead of PICO?
PEO is often useful when your question focuses on experiences, exposures, conditions or associations rather than comparing a specific intervention with another treatment or usual care.
Can PEO help with database searching?
Yes. The Population, Exposure and Outcome concepts can provide a starting point for search terms. Each concept can then be expanded with synonyms, alternative spellings and subject headings.
