PsycINFO Search Tips

We encourage students, researchers, and faculty members throughout NEOMED's campus and at our clinical sites to use this overview of how to search in PsycINFO for their research and instruction needs.

Overview: when should I use this database?

PsycINFO Contains more than 2.6 million citations and summaries of scholarly journal articles, book chapters, books, and dissertations, all in psychology and related disciplines, such as medicine, psychiatry, education, social work, law, criminology, social science, and organizational behavior. Collections date back as far as the 1800s. Ninety-eight percent of the covered material is peer-reviewed. Note: this tipsheet applies to the EBSCO version of this database.


Before you start searching, keep in mind . . .

Save your search in a document, citation management software (Endnote, Zotero, etc.), and/or the database

  • By saving your search, your strategy will be reproducible for another time and properly documented.

  • Explore options and instruction for citation management here, and find tips on how to export results.

  • To save searches in PsycINFO create an Ebsco account by clicking on the “Sign In” link in the upper-right corner of the screen. Then, click on “Search History” underneath the search boxes and “Save searches/Alerts.”

  • Create an alert within PsycINFO to receive updates on a topic. Follow the same steps for saving a search, but choose "Alert" instead.


Keywords

Keywords — How to Find & Use

  • Keyword terms can be single words or phrases.

  • Use quotes around all phrases to ensure that the phrase is searched instead of each word individually. (e.g. “public health”)

  • PsycINFO’s thesaurus lists synonyms for headings which can be useful for finding keywords.

  • To find additional ideas and/or synonyms, consult controlled vocabularies in other subject databases. For example, Embase has a controlled vocabulary called Emtree. Emtree records contain synonym lists similar to the "entry terms" listed beneath a heading in a MeSH record. The Emtree synonym list often contains European spellings/variations.


Controlled Vocabularies -- How to Find & Use

Locate Controlled Vocabulary

  • PsycINFO has a thesaurus that you can use to access it's controlled vocabulary. These are a standardized set of terms that are used to bring consistency to the searching process. Click here to learn more about the APA Thesaurus used by PsycINFO.

  • Terms are arranged hierarchically by subject categories with more specific terms arranged beneath broader terms.


Combining Searches Using Boolean Operators

  • A comprehensive and systematic search of PsycINFO includes both controlled vocabulary and keyword terms (i.e. free text, natural language, and synonyms).

  • Boolean operators are used to combine search terms. In PsycINFO, you can use the operators AND, OR, and NOT.

  • Boolean operators MUST be used as upper case (AND, OR, NOT).

    • OR--use OR between similar keywords, like synonyms, acronyms, and variations in spelling within the same idea or concept

    • AND—use AND to link ideas and concepts where you want to see both ideas or concepts in your search results

    • NOT—used to exclude specific keywords from the search, however, you will want to use NOT with caution because you may end up missing something important.

  • Go to the “Advanced Search” page to combine searches (in PsycINFO this is typically the default homepage). Your search history will be located above your results during your search session.


Applying Filters

  • On the left side of the screen, you will see an option to "Refine Results" with options for Source Types, Publication, Subject Headings, Language, Age, Gender, etc. To access the complete list of options for limits, click on the “Advanced Search” link beneath the search boxes at the top of the page.

  • Warning: filters such as species, ages, text availability, and subject discipline may unnecessarily exclude articles you want to see. When you apply these filters, you are using controlled vocabulary or database indexing to exclude articles. This is not always a reliable method of excluding articles.


Proximity Searching

  • PsycINFO allows for proximity searching through the use of two operators (N or W), along with a number to indicate the proximity of the words (up to 255 words).

  • N operator: The N operator stands for “Near Operator." Typing N5 would find two words within 5 words of each other without considering the order in which the words are entered. (therapy N5 sleep) looks for the word therapy within 5 words of sleep.

  • W operator: The W operator stands for "Within Operator." Typing W5 follows the order the words are typed. (therapy W5 sleep) would find “therapy for improved sleep,” but it would not find “sleep therapy”)


Truncation

  • In PsycINFO you can use a * at the root of a word to find multiple endings. For example:

arthroplast* will return arthroplasty, arthroplasties, arthroplastic, arthroplastics, etc.

mobili* will return mobility, mobilization, mobilisation, mobilize, etc.

  • You can also use a ? as a wildcard to search for letter variants within a word (e.g. wom?n finds women and woman)

  • In PsycINFO you can use truncation and phrase searching at the same time. e.g. "early childhood mobili*"


Field Tags

  • You can use field tags to specify where the database looks for the search term. In PsycINFO, first type the field tag and then the search term. e.g. TI Cardiology looks for cardiology in the title

TI — Searches the Title field

AB — Searches the Abstract field

AB OR TI — Searches the Abstract field and the Title Field at the same time 

AU — Searches the Author field

AF — Searches the Author Affiliation field (organization or university the researcher works for)

SO — Searches the Publication field (field to enter names of journals)

MH — Searches the exact PsycINFO subject heading, searching both major and minor headings

MM — Searches the exact PsycINFO subject heading, searching only in major headings


Accessing Full Text Explore all full-text options (including Interlibrary Loan - ILL)

In the NEOMED version of APA PsycInfo This link opens in a new window, the Northeast Ohio Medical University flame icon (pictured above) will often appear within an item record, with a link labelled "Explore all full-text options (including Interlibrary Loan - ILL)". To access the full text, click the NEOMED flame icon or on the "Explore all full-text . . ." linked text to go to an external page listing available full-text options. If the full text is not available, you will see a heading that says, "ILLiad - Request this item through interlibrary loan." When prompted, enter your ILLiad login and password and then submit the request via the pre-filled in template. The article will be emailed to you free of charge (only available for NEOMED students, faculty, and staff).
