AMA style

On This Page On This Page

AMA style, the short and abbreviated form of the American Medical Association. The style is written by the Journal of the American Medical Association and published by the Oxford University Press. It is a commonly used citation style for the publication of the journals published and issued in the Journal of Medical Association. Other than this, there are other citation styles also that are used by different subjects and fields of study.

The style is different from APA and MLA and unlike them, it follows the numerical referencing and citation style. The number is superscript and the number is followed by the complete reference in the list of references. The system is not as specific as some other citation styles but most of the medical journals and publications follow the AMA citation style.

Since there are many citation styles, especially the ones dealing with medical and technical subjects and topics, that follow the numerical referencing style, it becomes difficult to differentiate between them. This guide will help you identify the core differences between AMA and other citation styles.

What is an AMA Style Citation?

AMA style is most commonly used by the journals and publications of medical organizations. Besides AMA, NLM and AAA styles are also specifically developed to guide the publishers and editors of medical journals. The citation follows the numerical system in which a superscripted number is added with the direct quote or the paraphrased content in the paper. On clicking the superscripted number, the reader is directed to the full list of references at the end.

Besides the in-text citation, the list of references is also arranged in numerical order, which is unlike other citation styles including APA, MLA, and Chicago. What makes it different from other citation styles? There are a number of ways that make it different from other styles. Some of the key differences between AMA and other citation styles are given below:

  • The American Psychological Association (APA) is an accepted and standard citation style that uses the last name of the author and the year of publication in the parenthesis. The citation style is commonly used by students and researchers of the social and behavioral sciences.
  • The Modern Language Association (MLA) is used by the subjects of humanities and liberal arts. The citation style focuses on using and mentioning the author’s name and the page number in the citation.
  • Like AMA, IEEE also uses numbered citation and reference lists but they have distinct differences that make them different from other styles.

How to do AMA Style Citation and Referencing?

How to cite in the AMA style properly? Many students find it difficult to cite in this referencing style as it may look similar to other styles like IEEE. To help them, we have prepared an AMA-style guide that will explain everything in detail and in simple terms.

Unlike APAMLA, and Chicago citation styles, AMA-style citations use a numerical system of citation. When citing and formatting your paper in AMA style, make sure that you remember the following AMA style paper guidelines:

  • Keep a one-inch margin all around the page. Except, keep the right margin unjustified
  • All the main content of the paper will be double spaced while the title, headings in the paper, abstract, references, blockquotes and figures, and tables that are added to the paper
  • The preferred font style is Times New Romans while the font size is 12 pt.
  • Half inch indentation is added with every new paragraph
  • Place the title of your paper at the top left of the page’s header
  • The citation is identified with a superscripted number that extends into a full reference
  • The reference list is arranged in numbers and is added at the end of the paper
  • The paper could be written with or without a title page

AMA Style Title Page

The title page is the very first part of any paper or essay. Usually, the title page contains the full name of the student, the title of the subject and the paper, the deadline of the paper, and the name of the institution

Sometimes, the instructor tells the students not to add a separate title page. In such a case, instead of adding an entirely separate title page, add the header with details including the student’s name, the name of the instructor, the course title, and the deadline of the paper.

AMA Style In-Text Citation

Citations are added within the body of the paper. The main sections of the paper contain all the main sections, claims, explanations, and supporting claims of the paper.

When mentioning these sources or using them in your paper, it is important to credit these sources. How to credit them? By adding the in-text citations.

‘Williams has stated that the nation is moving towards industrialization and technology more rapidly than ever 1.’

Add the superscript number in front of the quoted text, facts, and ideas that have been added and discussed in the paper. What to do if more than one superscripted number? Separate them with a comma and add it as usual like below:

‘Storing latex at high heat may cause degradation,2,3 but it is difficult to keep materials cool in a desert environment.’

A superscripted number is added after the cited quote or idea. The number directs the reader to the complete citation in the reference list.

AMA Style Reference Page

Like the IEEE style, the AMA style of referencing follows the numerical or numbering system as all the sources are numbered in the list of references. However, the citation style has different formats and designs for different sources like books, websites, and journals.
