We can talk about the same issues using completely different words; if you only identify one of those words to search, you might miss some key research. Here is a little bit about the types of keyword development laid out below.
Choose what feels best to you and remember that the work you do now is to make your future research easier. This isn't something to do in your head - be sure to write as you go!
However you get started with research, just make sure you're coming up with multiple potential search terms and writing it all down!
Example Research Question: Is music therapy an effective method to treat the PTSD symptoms of military veterans?
Identify PICO:
Population: Military Veterans
Intervention: Music Therapy
Optional Comparison: Psychiatry
Outcome(/Symptoms): PTSD, lessening symptoms
This example breaks the research question into key areas to think about: the population you have selected, symptoms affecting that population or the improved outcome you are aiming for, and the intervention you are using to target those issues as well as considering anything you may compare that to.
We also want to brainstorm the other ways to describe important keywords to create a strong search strategy and find the best sources.
Sometimes those words may be synonyms but it's good to include terms that might help to broaden or narrow your searches too.
Here is a sample list of what this list of alt keywords might start with:
"Military Veterans" OR....
"Music Therapy" OR...
"PTSD Symptoms" OR...
Especially when you are just starting research, you may not know which word will be best for a particular database or the field of study until you start looking. Give yourself options!
