Integrated sessions: Identify key terms - health

Top

"The identification of the key words of a research study is the first essential step in identifying relevant literature. Unless this is done in a careful, logical way, you will probably fail to identify some of the key areas of literature"

Paul Oliver, Succeeding with your literature review

The first step in planning your search strategy is to identify key terms. It is important to consider the keywords related to your search topic and consequently establish appropriate terms. Rather than entering a whole assignment title or research question, you need to pick out the important words needed to describe your topic. The database will only look for what you type in, so for each keyword, you need to apply a few search tips.


Synonyms and related terms

Synonyms and related terms

When identifying key terms, you need to consider any synonyms (a word or phrase that means exactly or nearly the same as another word or phrase in the same language). If you're not sure what these might be, try finding a few relevant papers and see what terms are used in the title, abstract and subject headings.

Example: Synonyms of teenager would include: youth, juvenile, adolescent, young adult. Academic articles may refer to any of these terms so you should include all in your search

Formal and informal terminology

Formal and informal terminology

When searching it is important to consider formal and technical terminology alongside informal terms. Academic papers and articles may refer to either. 

Example 1: If looking for literature on 'heart attacks', you should also include formal terminologies in your search like 'myocardial infarction'.
Example 2: If researching cancer you can use the medical subject heading 'neoplasms'.

Acronyms and abbreviations

Acronyms and abbreviations

You should always consider acronyms and abbreviations for different words, phrases and even organisations when searching as authors may use either in their titles and articles. However, be cautious if this acronymn is used for lots of other irrelevant terms!

Example 1: 'Body Mass Index' is often shortened to BMI
Example 2: Advanced Nurse Practitioner would be ANP

American spelling and terminology

American spelling and terminology

It is important to consider American spellings and terminologies in a lot of literature searches. 

Example 1: Juvenile rather than teenager
Example 2: The American spelling of behaviour is behavior; organisation/organization; colour/color

Word endings and plurals

Word endings and plurals

When searching you should consider alternative word endings and plurals. The next page will introduce search operators to help you include these in your search. 

Example 1: If searching for 'therapy', you should consider whether alternative endings like 'therapies' or 'therapist' or 'therapeutic' are useful in your search.
Example 2: If searching for 'nurse', you should consider if nurses or nursing is useful in your search.
