Quantitative Doctoral Research

This guide will help direct you on how to use the library during your doctoral journey.

Help With Choosing Statistical Tests & Stats Software

For help in using these tools, there are many excellent video tutorials available online that will walk you through them.

How to Locate Tests, Measurements, or Instruments

There are many ways to locate possible tests or instruments to use for your research.

  • Searching across empirical studies during your literature review.
    • Recommended keywords in LopeSearch: survey or scale or instrument of test or measure or assessment or inventory
  • Searching dissertations in the same subject area and using the same methodology as your planned study.
  • Using the test databases, Health and Psychosocial Instruments (HaPI) or Mental Measurements Yearbook with Tests in Print (MMY).
  • Searching in Google Scholar.
  • Searching an open access archive of instruments.

You will also need to locate articles that support the validity of the instrument.

Library resources will generally include information about an instrument or test and how it has been used, but will generally not include the instrument or test itself. Most test or instruments require a fee or permission to be used. Doctoral learners are responsible for obtaining permission and obtaining legal copies of a test themselves.

  • The Library cannot contact test authors on behalf of learners.
  • Test manuals are generally not available through interlibrary loan.

Obtaining Instruments and Permission to Use Them:

  • To search for how to obtain an instrument, or who to contact for permission to use an instrument, we recommend searching the name of the instrument, enclosed in quotes, in Google's main search, rather than Google Scholar.
  • You may also need to search for the names of the instrument's authors.
  • ResearchGate , a social media site for researchers, is also a good place to search for the authors. You can sign up for an account, and often contact authors directly through the site.

Searching Using Published Dissertations

Searching Full Text in ProQuest Dissertations & Theses

  • To look for a possible instrument, look for a dissertation that uses the same research method and or the same framework as your proposed study. 
  • Specifics of the research method and the framework may not appear in the abstract, so you may need to search the full text of the dissertations.
  • To search full text, change the menu after "in" from "Anywhere except full text" to "Document text - FT."

change Anywhere except full text to Document text

  • Enclose exact phrases in "quotes" to keep terms together.

Searching in Library Test Databases

Searching in Mental Measurements Yearbook

  • Mental Measurements contains reviews of instruments, which includes information about publishers, costs, administration, and population.
  • MMY does not contain the instruments themselves.
  • Searches in MMY should use general keywords related to the attribute you wish to test.
    • For example: "Self-efficacy" or "Job OR Career AND Satisfaction."
  • Contact the listed publisher to obtain permission and the instrument itself.

Searching in HaPI

  • Health and Psychosocial Instruments contains records of instruments used and the articles they are used in.
  • HaPI includes articles for which GCU does not have access to the full text, these can be requested through interlibrary loan.
  • While HaPI may include a record for the original article for an instrument, it will not include the instrument itself.
  • Searches in HaPI should be general keywords related to the attribute you wish to test.
    • For example: "Self-efficacy" or "Job OR Career AND Satisfaction"
  • For records of articles that used an instrument, the record will include the information for both the secondary source--the article that used the instrument, as well as the primary source--the original article for the instrument. The secondary source is labeled as "Source" in the record, the original article is labeled as "References."

A HaPI record. the secondary source is labeled source, the primary is labeled as reference

  • Examine the articles that used a given instrument for more about it, including supporting articles such as validity research. For example the above article includes three references related to this instrument:

the references for this instrument include an article about validity

Searching Using Google Scholar

Advanced Searches in Google Scholar

  • 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

  • Searching for a phrase.
    • Click the menu in the upper left (the three bars) and choose " Advanced Search".
    • Enter the name of the instrument or the title of an article in the box for "with the exact phrase."
    • This will search for the instrument across the full text of articles, which is useful for locating articles using the instrument of validating it.
    • Search for the original article for an instrument or and instrument's manual, and use "Cited By" to see articles that list it in their references.
  • Searching for Authors
    • Enter an author's last name in "Return articles authored by" to search for an author's articles.
