Population: Parents of children without MMR vaccination.
Intervention: MMR vaccination education.
Comparison: Parents with no MMR vaccination education.
Outcome: MMR vaccination uptake. Change in attitude and beliefs.
Figure 1. Example of PICO with our research question
Now we can rewrite our research question using PICO:
Do parents who receive MMR vaccination education change their attitude and beliefs and/or level of MMR vaccination uptake with GPs, as compared to parents who do not receive the education intervention?
Figure 2. Revised question with PICO
Now, if you use PICO to develop your questions and terms the search will be more complex
than those we have done already, so the next step would be to write a literature review
protocol and decide which terms and which databases you might want to use e.g. PubMed,
PsycINFO.
See below for an example of possible terms you might use for your database searches.
