Primary concepts or keyterms can be identified using the PICO formula from Step 1. Each of the PICO elements can form a primary concept. If your PICO does not have a Comparison or Outcome (the outcome is broad or vague) element, it is okay to leave these concepts.
P: adolescents with depression
For each primary concept identified, make a list of other terms with the same or related meaning (synonyms). It is important to gather synonyms, because
Terms have different spellings, plural forms, acronyms, full form of acronyms
Concepts are described inconsistently across time, geographies or even among researchers
Terms have same/close meaning, disciplinary jargon
Umbrella terms vs specific names
These terms will form the textwords of your search strategy.
