An online instructional tool to orient users to the NYU virtual environment: books, databases, articles, more.

A Background Question: Therapeutic Touch in CINAHL, Limiting to Reviews

In Module 1 of the tutorial you learned that often a literature search seeks to answer a "background question" (looking for overview or summary information about a disease, a problem, or a population). Secondary sources such as:

  • encyclopedias, textbooks, drug directories
  • print and online summaries
  • "point of care" summaries  (such as Nursing Reference Center, see box on the right >>>>>>)

may help with this type of question. Additionally, an up-to-date research article or a "review" article on a broad topic may also summarize the state of the art for a background question.

 

An overview or background question for an article search might be:

"Is there recent evidence to support the effective use of therapeutic touch in the elderly?"

 

Searching for Content:

First we address the content of the question:  therapeutic touch.

Using an article database like CINAHLPlus, the key word search therapeutic touch retrieves more than 8400 articles!

Narrowing the Content:

One way to begin to restrict results and increase relevance is to notice the CINAHLPlus Subject headings. They may be seen as descriptors for the most relevant results as you browse.  Or you may search the online thesaurus "CINAHL Headings" at the top of the search page. The record below depicts revised search results, based on a search for the term Therapeutic Touch as a Subject Heading (not as a key word). The results are now shown with 404 results. When an index term is applied to an article citation, it indicates the term is a topic of the article, rather than just a key word(s) that might appear in the abstract.

 

Limiting for Article Type:

Once we have located the subject terms for content, we can use LIMITS to find a Review article, secondary source material. 

In CINAHLPlus, a Review article is defined as: "a review of the published literature that can cover a wide range of subject matter of various levels of completeness or comprehensiveness. The presence of research findings or case reports does not preclude designation as a review."

 

Popular Limits appear in the Refine Your Results (left menu) of the CINAHLPlus screen. For more limits, choose Show More in left menu, then select an option for Publication Type:

 

 

Below is a sample search result based on the limit to Publication Type: Review

 

Below is an example of another CINAHLPlus search limiting by Publication Type, this time the result of limiting to Publication type: Research

 

In CINAHLPlus, a Research article is defined as: "an original (includes SECONDARY ANALYSIS), complete research study containing data collection, methodology, discussion of results, etc." 

You have seen how to apply LIMITS to answer a background question such as the use of therapeutic touch in the elderly by locating a Review article.

And you have seen a way to raise the level of evidence in a search by limiting to a Research article.

To further limit to an age group, you could use the limit to restrict to Age Group: Aged (65 and over).

The next module will show how to apply LIMITS and raise the level of evidence for a foreground question.
