AMA (American Medical Association) is most commonly used in health science and medical fields. It involves the general format of a paper, in-text citations within the body of a paper, and reference list at the end. It is important to note that in most cases, every reference should have an in-text citation. Inversely, every in-text citation should correspond to a reference in the reference list.

AMA provides the following formatting rules for writing assignments:

  • AMA does not have a standard for line spacing, however most professors prefer double-spacing
  • 1″ margins on all sides
  • 12-point sized font
  • Times New Roman or Arial font
  • Title page:
    • Title of paper
      • Capitalize it like a sentence
    • Your name
      • First name, middle initial, last name
    • Name of school
    • Abstract
      • It should contain the objective of the study, the main concepts explored, the study design and methodology; and the main conclusions of the study
  • The header:
    • First page only, left-hand side
      • Running head: TITLE OF YOUR PAPER
    • Rest of pages, left-hand side
    • Right-hand side of every page
      • Page number

In-text citations are found within sentences and paragraphs of assignments and make clear that the information quoted or paraphrased comes from a specific source found on the Reference page. IMPORTANT: An in-text citation is necessary whether the information used is directly quoted from a source, or if it is paraphrased.

AMA handles in-text citations differently than APA or MLA. Each reference should be cited in the text by placing a superscript arabic numeral at the end of the sentence where the reference is used. If multiple sources are used in a single sentence, separate each number with a hyphen (see examples below). Superscript in-text citations should appear outside periods and commas, and inside colons and semicolons.


A single source at the end of a sentence

admitting you need help is the first step.2

Multiple sources at the end of a sentence

admitting you need help is the first step.2-3

Format the reference page using the following rules:

  • “References” is written in bold at the top-center of the page. Do not include the quotation marks.
  • Start at the top of the following page after the paper ends.
  • Number the references in the order they appear in the text.

Below are examples of the types of sources most commonly used. When creating a reference pay attention to all of the details. What needs to be italicized? How should things be capitalized? When and where do you need a period? All of these are important to creating a properly formatted reference.

Journal Article, Magazine, and Newspaper Articles

If you’re missing information needed for a reference, don’t assume it doesn’t exist. A quick Google search of the article title can help locate missing information.

An article in a scholarly journal with issue numbers but no volume numbers

Cheuk B. Delivering business value through information literacy in the workplace. Libri. 2008: 137-143.

An article in a scholarly journal with volume and issue numbers

Washington ET. An overview of cyberbullying in higher education. Adult Learning. 2015; 26(1): 21-27.

An article with more than six authors

When there are more than six authors, write out the first three authors followed by ‘et al’. This rule applies to all types of sources.

A magazine article

Citing a magazine article is the same as citing a journal article.

A newspaper article

When referencing books, be sure to know whether someone is an author or editor. This distinction can be unclear when looking at the cover of a book. Again, a Google search can help confirm the information you have, or find the information you are missing.

Encyclopedia or Dictionary Entry

When using multiple entries from an encyclopedia or dictionary, provide one reference for the entire book. The same in-text citation is used no matter which entry you use in the assignment. If only a single entry is used, provide a reference for that specific entry.
