Psychology: Preparing for Literature Reviews

This guide highlights library and internet resources relevant to counseling and psychology at Grand Canyon University, including online article databases, electronic books, and more.

Guide Books for Literature Reviews

How to Get Started With a Literature Review

The literature review section of the dissertation or DNP project is expected to be thorough, broad, and in depth. The guide books above and the selection of articles below can help you make sure you are taking a thoughtful and complete approach to your search. Also on this page is advice for digging deeper in library databases and Google Scholar.

Literature Search Logs

Advanced Searching for Literature Reviews

There are many ways to expand your searches to locate additional articles. Below are tips for the following methods to locate new articles:

  • Exploring all the databases for a subject.
  • Removing the Full Text limit.
  • Seeking out review articles.
  • Adjusting keyword fields.
  • Using Google Scholar.
  • Exploring the full issues of key journals using Find Journals by Title.
  • Reviewing the reference lists of published dissertations.
  • Use citation analysis tools. See the citation analysis page for more

How To Locate Additional Databases

To display different subsets of databases, use the menu bar in the middle of the page.

Browse by Subject will allow you to choose a subject by which to filter the databases that display.

When you choose a subject, only relevant databases will be listed.

To return to the full list, click on Clear Filters/Browse All Databases:

the button is labelled clear filters

You can also browse through the databases by title by clicking the letter on the alphabet list that the title begins with.

Uncheck Full Text to Expand a Search

  • Turning off "Full Text" limits.
    • Most databases default to showing only those articles for which they have the full article available immediately in the database. For in depth research, you will need to turn off this setting to see articles for which the database has only the abstract.
    • Request articles found this way through Interlibrary Loan (Tipasa).
    • Full Text in EBSCO is part of the filters menu at the top and on the expanded filters menu that will open on the right.

Full Text is under Limit To

  • Full Text in ProQuest also appears in the search options to the left.

  • Full Text in Sage. For Sage's advanced search, 'All Content' under 'Access' Type includes articles for which the GCU Library does not have full text access.

  • Full Text in Gale is under "More Options" and is off by default in some databases.

Gale has the full text control under more options

How to Locate Review Articles: Systematic Reviews, Literature Reviews, and Meta-Analyses

  • Start with your general topic area. For example:
    • handwashing or hand washing or hand hygiene or hand sanitation
    • AND nurs*
  • Add a search field for review type articles:
    • systematic review or meta-analysis or literature review or scoping review
  • Adjust dates to be within 2 years. 

Why review articles?

  • Review articles will have surveyed the literature extensively, providing a reference list you can draw from.
  • Most reviews will also include their search strings. This can add to your own keywords to expand your searches.
    • For instance the above search was used to locate this article:

Seo, H.-J., Sohng, K.-Y., Chang, S. O., Chaung, S. K., Won, J. S., & Choi, M.-J. (2019). Interventions to improve hand hygiene compliance in emergency departments: a systematic review. The Journal of Hospital Infection, 102 (4), 394–406. https://doi.org/10.1016/j.jhin.2019.03.013

  • Within this article, their search includes the following string:
    • (hand antisepsis or handwash* or hand wash* or hand disinfection or hand hygiene or surgical scrub*)
    • With additional terms that should be included when searching on this topic listed in the article narrative.
  • Review articles can also point towards a gap or the need for further studies. For instance, this article states:
    • "Further well-designed controlled studies are necessary to examine the true effects and identify which intervention modalities are more effective than others for HHC improvement in EDs."
    • Reviewing the articles this article studied would then provide support for this gap.

Pursuing a health care topic? Search Cochrane Reviews or Joanna Briggs EBP as well as the more general databases.

How to Use the Field Options in LopeSearch

  • The "All fields" options allow you to change where in the record or document the database searches for your keywords.
  • Using these options allows a targeted search, giving different levels of importance to different sets of keywords.
  • The field options in EBSCO (the LopeSearch and other databases) include:
    • All fields —The default setting searches title, author, abstract, keywords, and subjects. 
    • All Text—Searches include the full text of the article and all other fields.
    • Author—Searches only the authors.
    • Title—Searches only the title.
    • Subject Terms—Searches only the subject terms.
    • Journal Title/Source—Searches only the journal name.
    • Abstract—Searches only in the abstract.
  • When using the field options, consider which parts of your search should be the focus--terms which would need to be key to the study, and thus would appear in the title or abstract, and which terms might be talked about but not appear in the abstract, title, or subject terms.
  • We highly recommend speaking to a librarian when developing an advanced search.
  • You can click the + (in some databases: "add a row") to add more than the 3 search boxes provided by default.

Example 1:

Research question: “Why less African-American women are promoted to leadership positions in career opportunities within the mental health professions?”

Box 1:  women or female or woman or females or gender  FIELD option: AB Abstract

Why? The gender of the study population is more likely to be a principle aspect of the study when mentioned in the abstract. Looking in the full text however would get too many false positives for incidental mention of these words.

Box 2:  African Americans or black Americans  FIELD option: TX All Text

Why? Race may or may not be mentioned in the abstract. Looking in the full text allows this search to also turn up studies that looked at women in general, but reported out on race or ethnicity as a variable.

Box 3:  career or job or work or workplace or occupation or profession* or employ* FIELD option: SU Subject Terms

Why? Restricting this aspect to subject ensures that career considerations were the purpose of the study.

Box 4:  promot* or advancement or hiring or hire or disparities or inequality or equity or gap or discrimination FIELD option: TI Title

Why? These words can occur a lot incidentally. Ensuring they appear in the title reduces irrelevant results when they should be the focus of the study. 

Box 5:  method* and (results or findings) FIELD option: TX All Text

Why? This keyword set helps narrow down the search to empirical or original research studies in databases that do not have filters for it.

Example 2:

Research question: "What is the role of self efficacy in the success of Black students in college?"

Box 1: African American or black or race or racial or ethnic* or minority FIELD option: Select a Field

Why? This search is looking for race or ethnicity to be a central part of any study returned, so it should be mentioned in the title, subject terms, or abstract. 

Box 2: higher education or university or college or post-secondary or undergrad* FIELD option: AB Abstract

Why? This search is looking for the academic level to be mentioned as a key part of the study, and thus appearing in the abstract.

Box 3: self efficacy or self concept FIELD option: Select a Field

Why? This is the theoretical concept that needs to be prominent to match with the researcher's research question.

Box 4: method* and (results of findings) FIELD option: TX All Text

Why? This keyword set helps narrow down the search to empirical or original research studies in databases that do not have filters for it.

Box 5: NOT health* or medical or diabetes FIELD option: Select a Field

Why? In previous searches, a number of articles related to these keywords appeared. They are not what the researcher is looking for, so using NOT eliminates them from the search. Use NOT carefully to ensure you are not being overbroad.

Finding recent papers

Your search results are normally sorted by relevance, not by date. To find newer articles, try the following options in the left sidebar:

  1. click "Since Year" to show only recently published papers, sorted by relevance;
  2. click "Sort by date" to show just the new additions, sorted by date;
  3. click the envelope icon to have new results periodically delivered by email.

Locating the full text of an article

Abstracts are freely available for most of the articles. Alas, reading the entire article may require a subscription. Here're a few things to try:

  1. click a library link, e.g., "Full-Text@GCU", to the right of the search result;
  2. click a link labeled [PDF] to the right of the search result;
  3. click "All versions" under the search result and check out the alternative sources;
  4. click "Related articles" or "Cited by" under the search result to explore similar articles.

If you're affiliated with a university, but don't see links such as "FindIt@Harvard", please check with your local library about the best way to access their online subscriptions. You may need to do your search from a computer on campus, or configure your browser to use a library proxy.

Getting better answers

  • If you're new to the subject, it may be helpful to pick up the terminology from secondary sources. E.g., a Wikipedia article for "overweight" might suggest a Scholar search for "pediatric hyperalimentation".

  • If the search results are too specific for your needs, check out what they're citing in their "References" sections. Referenced works are often more general in nature.

  • Similarly, if the search results are too basic for you, click "Cited by" to see newer papers that referenced them. These newer papers will often be more specific.

  • Explore! There's rarely a single answer to a research question. Click "Related articles" or "Cited by" to see closely related work, or search for an author's name and see what else they have written.

To find the Advanced Scholar Search, click the Menu option located in the upper left corner.

Click on Advanced Search.

the google scholar menu has advanced search as an option

A new box will pop up. 

Example Searches:

This Advanced Search is searching for articles on the benefit of teaching information literacy in schools.

The words  benefit  and  teach  will both be found somewhere in the article.

The phrase  information literacy  will also be in the article. 

One of these words or a combination of these words-- school  or  education  or  college  or  university --will also be in the article. 

Articles will have been published from 2010to present. (Leaving the second box empty will automatically search until present day).

This Advanced Search is searching for articles on the connection between academic success and libraries. 

The phrase academic successwill be found in the article. 

Either libraryor libraries(or both!) will also be found in the article. 

Academic successand libraryor librarieswill be found in the titleof the article. 

This Advanced Search is searching for articles written on social learning that were authored by Albert Bandura. 

The phrase social learningwill be found in the article. 

All articles will be authored by  Albert Bandura.

Browse a Journal's Articles

  • Keep an eye out while researching for the names of journals that come up often.
  • Read through that journal's recent issues, you may find articles with related content that is worded in ways you have not thought of.
  • To locate a journal to browse by issue:
    • Search for the journal title in the Find Journals by Title search.
    • Choose the database that lists 'to Present' for the journal. For example this journal, Electronic Library is in Emerald Management:

The journal Electronic Library has the years 1998 to present in Emerald Management

  • Different databases display issues in different ways. Below are examples from Science Direct, ProQuest, and Emerald. Click on an issue to view all the articles from the issue.

  • Journal you need not one the library subscribes to? Most journals will list the titles and abstracts of their latest articles on their website. You can then request any article of interest through Interlibrary Loan .

Citation Alerts in Web of Science

Have a key paper? Get alerted when a new paper that includes it in their reference list is published!

In addition to the tips below for setting alerts in Web of Science, Google scholar and many individual databases also have search alert features that will notify you when new articles match the criteria you set up. Check out the search alerts page for how to use this feature in the databases that offer it. 

What Are Empirical/Research Articles?

At various points in your educational journey, you will need to find empirical articles for many class assignments, capstones, and research projects, including doctoral DNP projects and dissertations.  

Some of the databases have specific filters to help you narrow your results to empirical articles or labels to identify them quickly. These are outlined in the section below, as well as how to find articles in databases without these filters.

An empirical article reports on the outcome of a study based on observation or experiment carried out by the author(s).

These can also be called primary or researcharticles. They contain original data and the conclusions of the researchers involved in an experiment or study.

The two main sections of an empirical article are the methodology (sometimes called the design) which describes how the study was carried out, and the results (sometimes called the findings) which lays out and analyzes the data or observations which were found. Both quantitativeand qualitativearticles are empirical.

Qualitative Research

Qualitative research includes all modes of inquiry that do not rely on numbers or statistical methods. (Encyclopedia of Nursing Research, 2012, Springer). Qualitative research typically involves interviews, surveys, or questionnaires.

Quantitative Research

Quantitative research consists of the collection, tabulation, summarization, and analysis of numerical data for the purpose of answering research questions or hypotheses. (Encyclopedia of Nursing Research, 2012, Springer).

It would be great if all empirical articles were labeled with the words "Empirical" or "Research Article." Unfortunately, most of them aren't. Instead, the article has to be read and analyzed to determine if it is empirical. Empirical articles have certain features that identify it as empirical. Look for these features to decide whether an article is empirical.

Introduction- This section introduces the article. It gives an overview of the problem, and the rationale for the study. The research hypothesis or research question is provided. 

Literature Review- In this section, the authors review previous research that is relevant to their study. This may include key concepts, theories, or similar studies.

Method- This section describes the original research study conducted by the authors. It includes the research methods used, the population sample, and the data collection process.

Results- Also called discussionor findings. In this section, the authors discuss the results of the study. This includes analyzing the data, drawing conclusions based on the data, and determining whether their hypothesis/research question was correct.

Conclusion- This section summarizes the research study and provides suggestions for future research. Looking at the suggestions for future research is a great place to find the gap in the literature. 

References- A list of all the sources the authors used in conducting their research and writing the paper. 

To begin working with empirical/research articles, the Library recommends viewing the video How to Read and Understand a Research Study from Sage and reading Evaluating Research Studies from the Handbook of Research Design & Social Measurement .

  • When beginning to read in a new discipline, you will need to build knowledge of terminology.
    • Course readings, textbooks, and reference databases like Credo below are an excellent way to develop discipline specific vocabulary.
  • Is the journal one you are familiar with?

Most research articles follow the same basic layout, with the same general sections.

the abstract is a recap and usually comes first, the introduction explains why a study is done

Abstract

The brief summary or recap of the article.

  • Read the abstract before the article!
  • The abstract will tell you an overview of what they did and what the results were.

introductions should explain why the study needed to be doneIntroduction

This section introduces the article. It gives an overview of the problem, and the rationale for the study. 

  1. Read the intro first.
    • Look for:
      • Why was this study necessary?
      • What question were they trying to answer?
      • What's the point of this research?
      • What's the bigger context for why research in this area is being done?
      • A good research objective is measurable, realistic, and timely. 

 Pause.

Check your understanding here.

  • If the abstract and introduction aren't making sense, do more background research before reading the rest.

results sections tell what happened

Results

Also called Discussion or Findings.

The results of the study. This includes analyzing the data, drawing conclusions based on the data, and determining if the hypothesis/research question was correct.

  1. Read Results second. This allows you to immediately compare the question with the answer. 
    • Look for:
      • Are the conclusions in line with the research questions? 
      • Do they discuss limitations or flaws in the results?

Conclusionconclusions cover the interpretation of the results

Summarizes the research study and explains what conclusions the results support. 

  1. Read after the results. Make sure to compare the conclusion to the introduction. 
    • Look for:
      • A clear answer to the research question established in the introduction.
      • Why the findings matter.
      • What additional research needs to be done in this area.

the method section covers the howMethod

The research methods used, the population sample, and the data collection process. The actual study part of a study.

  1. Read the methods last.
    • The methods section will generally be the most technical section, so reading and understanding the other parts will make understanding it easier.
    • Compare the methods to the conclusion.
    • Look up methods in Sage Research Methods if you aren't familiar with them.
    • Look for: 
      • Does the design make sense? Especially given the conclusions. 
      • Do they identify the analysis and scales clearly? Are these validated scales that have been used in other studies?
      • Does the sample size match the conclusions made?
        • Watch out for claims of significance or absolute findings when dealing with a small number of subjects.
        • Be aware of p -hacking.

References

A list of all the sources the authors used in conducting their research and writing the paper. 

  • Check the references if you want to follow up on a study mentioned in the paper, for the full information to locate it.

Some articles may also include a section reviewing other studies that did the same or similar research, called a literature review.

  • If there is one, look for: 
    • Are they in line with or contradicting prior research?

Two types of review articles will sometimes appear in searches for empirical articles, including when using database filters. While they are secondary sources and do not represent primary research, they are important overviews of the current state of research. A recent review or analysis can be a useful source of articles. They can also point towards gaps in research or areas for further study.

Meta Analysis

Meta-analysis is a quantitative approach that permits the synthesis and integration of results from multiple individual studies focused on a specific research question. (Encyclopedia of Nursing Research, 2012, Springer).

Systematic Reviews

Systematic reviews are overviews of research evidence that address a specific clinical question. The purpose of the systematic review is to provide a more comprehensive synthesis and evaluation of the state of the science in the area of interest. (Dictionary of Nursing Theory and Research, 2010, Springer).
