AMA Citation Style Guide 10th Edition Made Simple

The AMA Citation Style Guide (10th ed.) is a comprehensive reference guide developed to align with the standards set by the American Medical Association for citing sources in medical and scientific writing. The guide provides detailed instructions on how to format citations and references for various types of sources. The AMA style ensures consistency and accuracy in scholarly publications. It is based on the AMA Manual of Style: A Guide for Authors and Editors, 10th edition, published by Oxford University Press in 2007.

General Principles of Formatting

The AMA Manual of Style is not very specific about formatting requirements, and students should usually follow the instructions of their professors. If none are provided by the instructor, the following are the style recommendations.

• All text in an AMA-styled document should be double-spaced, including the title page, abstract, body text, and tables, except for the abstract and references, which should be single-spaced. This enhances the readability of the document.
• Like other formatting styles such as APA, MLA, Chicago, Harvard, Vancouver, and OSCOLA, the AMA style requires paper margins to be 1 inch (2.54 cm) on all sides. This provides a consistent and professional appearance to the document.

• Font Types and Sizes
  • While any font type is acceptable, it is recommended to use a 12-point font size. The AMA style suggests using two typefaces—a serif font for body text and a sans serif font for titles and subheads—with appropriate styles like bold and italics to emphasize scholarly content.
• Page Numbers
  • Every page of the document should be numbered, starting with the title page. Typically, page numbers are placed in the upper left corner of each page.

Papers written in AMA are required to have four sections:

• Title Page
• Abstract (structured or unstructured)
• Body (introduction, methods, results, discussion)
• References

AMA Title Page

AMA style does not have strict rules about formatting the title page; however, it should include several crucial

features:

• Title
• Authors’ Name
• Degrees (above bachelors)
• E-mail Addresses
• Institutional Affiliation
• Word Count (for text only, excluding title, abstract, references, tables, and figures)

Remember that every instructor may have his or her preferences when organizing the title page.

AMA Abstract Guide

Abstracts are written on a separate page.

In AMA style, the abstract is always placed on its own distinct page to ensure clarity and separation from the main content. This practice helps maintain the organization and professionalism of the document. It also allows readers to easily reference and locate the abstract without scrolling through the main text.

The word “Abstract” is written in UPPER CASE, left-justified, boldface, and has a triple space after it.

The heading “ABSTRACT” should be prominently displayed at the top of the page, using upper case letters to distinguish it from the rest of the text. It should be left-justified and bolded to stand out clearly. A triple-space should follow the word “Abstract,” creating a visual break before the abstract text begins.

The text on the abstract page is NOT indented.

 Unlike the body of the document, the text within the abstract should not have any indentations. This format provides a clean and straightforward presentation of the abstract content. It ensures that the abstract is easily readable and visually distinct from other sections of the paper.

The sections of the abstract are single-spaced with double spaces between them.

Within the abstract, each section should be single-spaced to condense information efficiently. Double spaces should separate different sections to provide clear distinctions between them. This formatting helps maintain a structured and organized appearance, aiding in the reader’s comprehension.

Structured abstracts are used for original data, systematic reviews, and clinical reviews; they are usually limited to 250-300 words.

Structured abstracts, which include specific headings like Background, Methods, Results, and Conclusions, are required for original research, systematic reviews, and clinical reviews. These abstracts provide a detailed and methodical overview of the study, ensuring that key information is succinctly presented. The word count for these abstracts typically ranges between 250 and 300 words to keep them concise yet informative.

Unstructured abstracts are used for every other manuscript and are limited to 150 words.

 For other types of manuscripts, such as commentaries or case reports, an unstructured abstract is appropriate. These abstracts do not follow a specific format with headings and are generally brief. They are limited to 150 words, providing a quick summary of the content without detailed sectioning.

3-10 keywords should be placed after the abstract

 Following the abstract, a list of 3 to 10 keywords should be provided. These keywords are crucial for indexing and search purposes, helping other researchers find the document in databases. Placing them right after the abstract ensures they are prominently displayed and easily accessible.

Headings

Level 1. Left-aligned, Bold, Uppercase, and Lowercase. Double Space After.

Level 2. Centered, Italicized, Uppercase, and Lowercase. Double Space After.

Reference List

The reference list is put on a separate page with the title “References” in bold and left-hand justified on the top of the page. Every source used in the body of the paper must appear in the reference list. Here is the list of

requirements for the organization of this page:

• All the references are numbered and listed in the order they appear in the body of the paper.
• Reference numbers are indented 0.25″.
• The reference page is single-spaced with double spaces between entries.
• Regardless of the type of source referenced, a comma is never inserted between the last name and the first name of the author.
• If a piece of information and/or idea is borrowed from a specific page or range of pages, numbers of the said pages should be identified at the end of the corresponding reference.

The authors’ last names are fully spelled. First name and middle name initials are put after the last name with no periods or commas between them.

Example:

1. Wolf ZR. Nursing practice breakdowns: Good and bad nursing. Medsurg Nursing. 2012;21(1):16-36

When identifying page numbers, be sure to put them in full without shortenings. In addition, there are no spaces after the year of publishing.

Example of an incorrect entry:

1. Riley JB. Communication in Nursing. 8th Ed. St. Louis, MO: Elsevier. 2017: 111-7.

Example of a correct entry:

1. Riley JB. Communication in Nursing. 8th Ed. St. Louis, MO: Elsevier. 2017:111-117.

Key Differences Between AMA Style Guide and APA Style Guide

AMA EndNote Style

AMA EndNote is a powerful citation management software developed by Rowan University, designed to streamline the process of organizing and formatting references for research papers. Utilizing the American Medical Association (AMA) style, EndNote allows researchers to seamlessly integrate citations within their work using a combination of commas, spaces, and semicolons to clearly define sources. This structured approach ensures that all references are consistent and easy to follow, which is crucial for maintaining the integrity and readability of academic papers.

EndNote’s utility extends beyond mere citation formatting. It automates the organization of references, enabling researchers to import bibliographic data directly into their documents with ease. For example, a researcher working on a study about the effects of a new drug might use EndNote to create a customized library of sources, including journal articles, books, and websites. This library can be tailored to meet the specific needs of the study, allowing for quick and efficient retrieval of relevant information. Furthermore, EndNote’s customizable libraries and integration with word processing software like Microsoft Word ensure that references are formatted correctly according to AMA guidelines, significantly reducing the potential for errors. By automating these tasks, EndNote allows researchers to focus more on their actual research and writing, enhancing overall productivity and accuracy.

Tools for AMA Citation

Reference Management Software

Software like EndNote, Zotero, and Mendeley can help manage and format citations.

Online Citation Generators

Online tools like Citation Machine and BibMe can generate AMA citations.

References

Citing Governmental Sources

Government publication

1. United States Congress House Committee on Energy and Commerce. DOE for the 21st century: Science, Environment, and National Security Missions. E&C Publication No. 114–119. Washington, DC: U.S. Government Publishing Office. Published November 16, 2017.

AMA In-text citations

Superscripts are used in AMA citation style to acknowledge the original author of an idea or piece of information that a student has borrowed. The superscript number goes to the left of colons and semicolons and to the right of periods, commas, and quote marks. When citing sources in a sentence, use distinct superscript numbers to give due credit to each source.

Example:

The engineer announced that the house was built on solid ground; however, the observers doubted that. When using direct quotations, the superscript number is put outside the quotation marks.

Example:

“The role of obesity on the development of allergic rhinitis is not well defined, whereas allergic rhinitis may have an impact on obesity.”¹

If the direct quotation is four lines or longer, it should be indented and put into a distinct section with a reduced type. In this case, no quotation marks are needed.

Example:

The report states:

Allergic diseases, such as asthma and allergic rhinitis, are prevalent long-term inflammatory conditions affecting the airways. Obesity is a prevalent condition in children and is associated with a higher likelihood of developing asthma. Obese individuals with asthma often experience more severe symptoms and do not respond effectively to conventional asthma treatments. Conversely, children who have asthma may have a heightened susceptibility to obesity, indicating that there is a mutual connection between asthma and obesity.¹

When citing the same source more than once, include the page number in the reference in parentheses.

Example:

The engineer announced that the house was built on solid ground.¹⁽¹⁴⁾
