In CINAHL Plus with Full Text, you can search or browse the CINAHL Headings, or you can get the database to "suggest subject terms".
To search or browse CINAHL Headings, click on the link and follow the prompts.
To match your topic or idea to subject terms, enter your topic/idea/concept in the first search box, tick the box for Suggest subject terms, and click on Search.
Let's use "stuttering" as an example. If you search the CINAHL Headings for items that contain "stuttering", or if you ask the database to suggest subject terms for "stuttering", you get this screen:
Clearly, the suggested CINAHL Heading (subject term) for stuttering is Fluency Disorders.
From here, there are a number of things you can choose to do......
If you tick the box for Fluency Disorders, you are presented with a list of subheadings. The default is to Include all Subheadings, but you can narrow your choice to one or more. If you choose more than one subheading, the database will combine these with the OR operator. The idea is to work across the screen from left to right. Your selection(s) appear in the Search Term box, and you click on Search Database to actually search for articles.
Note that you are given the option to search for your original terms as a keyword. If you choose the original term (stuttering) as well as the suggested CINAHL Heading (Fluency Disorders), the search will combine these with the OR operator.
If, rather than tick the box for Fluency Disorders, you actually click on the subject heading itself, you are taken into the tree view of the subject headings - that is, the subject heading hierarchy. This can be a help because you can see broader and narrower terms, and you might choose to use these as alternative search terms. At this screen, you can proceed to search for one or a combination of subject headings.
You can also:
Once again you work from left to right, with your selection(s) appearing in the Search Term box, and you finish the process by clicking on Search Database.
