What Is The AMA Style Of Medical Writing?

The AMA style of medical writing is a standardized citation and formatting system used widely in medical and scientific fields. It ensures that sources are properly credited, making it easier for readers to verify facts and follow up on research.

The AMA style focuses on clarity, precision, and uniformity, which is critical in medical writing where accuracy is essential. Citations are numbered in the order they appear in the text, with the reference list following the same sequence.

The format includes specific guidelines for citing books, journals, websites, and other sources, along with rules for abbreviations, page numbers, units of measure, and headings. This helps in ensuring consistency across medical publications.

AMA Style In-Text Citations Overview

In AMA style, in-text citations are crucial for acknowledging sources and guiding readers to the corresponding references. These citations follow specific rules that ensure clarity and consistency.

Below are the key components of in-text citations in AMA style, explained in detail.

Superscript Numbers

In the AMA style of referencing, sources are cited using superscript numbers that correspond to the reference list at the end of the document. These numbers are assigned in the order of appearance in the text, and they remain the same if cited again.

Superscript numbers should be placed outside punctuation, such as periods (full stops).

Example: The study revealed a significant increase in heart disease risk.1

Whereas in the case of a colon or semicolon, the number must be placed beforehand.

Example: The study revealed a significant increase in heart disease risk1; further research is needed to understand the underlying factors contributing to this trend.

Author Names

Unlike other citation styles, AMA does not use complete author names directly in the text for in-text citations. Instead, citations are referenced with superscript numbers. However, if an author's name must be mentioned for context, it is done naturally within the sentence, without a parenthetical citation.

Always keep in mind, when mentioning an author, only include their last name.

Example: According to Smith,2 the new findings challenge previous research.

If there are two authors, name both.

Example: According to Smith and Joe,2 the new findings challenge previous research.

For sources with more than two authors, or if an author is part of a group, list the first author’s last name followed by the term "et al.," to represent the rest.

Example: According to Smith et al,2 the new findings challenge previous research.

Direct Quote

When directly quoting in AMA style, the superscript number should be placed after the quotation, and the exact page number just after this number. Short quotes are integrated within the text, while long quotes (40 words or more) are set as block quotes, but still use the superscript for citation.

Example: Elena claims that “The treatment was shown to be ineffective in 50% of the cases.”5(p50)

Cite Multiple Sources

To cite multiple sources within the same sentence, list the superscript numbers in ascending order, separated by commas.

Example: Several studies have confirmed this finding in different populations.1,4,6

For consecutive sources, use a hyphen to indicate a range. This allows you to acknowledge multiple references without repeating citations.

Example: Several studies have confirmed this finding in different populations.4-6

Page Numbers

When including page numbers, such as for quotations, place them in parentheses immediately after the citation number, with no spaces in between. Use "p" for a single page and "pp" for multiple pages or a range of pages.

Example: As noted in the results, the data was gathered from a sample of 500 patients.7(p35)

Example: As noted in the results, the data was gathered from a sample of 500 patients.7(pp34-36)

AMA Style Reference List Overview

At the end of your AMA-style paper, the reference list provides full details for each source cited in your work. These references are numbered in the order they first appear in your text, with each source assigned a unique number that remains consistent throughout.

Every source is listed only once, no matter how often it’s referenced or cited. A typical reference entry includes the author’s last name and initials, the title of the work, publication details, and the date.

The specific formatting depends on the type of source, ensuring proper credit and clarity for readers. For further clarification, have a look at the table provided next.

AMA Style Paper: Best Formatting Guidelines & Tips

When writing a paper using AMA style, there are specific guidelines to follow regarding layout, spacing, and citation. Ensuring your paper adheres to these formatting rules is key to maintaining a professional and scholarly appearance.

Below is a breakdown of essential formatting details.

Title Page

The title page must feature the paper title, authors, institution name, course title, and date. Position all this information in the upper half of the page, ensuring it is centered and double-spaced.

Avoid using bold, italics, or different font sizes for this information. List the author's first name, middle initial, and last name without including titles or degrees.

Context -> Evidence Acquisition -> Results -> Conclusions

Objectives: To explore the relationship between nutrition and mental health among adolescents.

Methodology: This study analyzed data from various sources to assess dietary habits and their impact on mental well-being.

Results: Findings indicate a significant association between balanced nutrition and improved mood stability in adolescents.

Conclusions: The evidence suggests that a well-rounded diet may play a crucial role in enhancing mental health in young people, highlighting the need for further investigation into nutritional interventions.

Key Words: nutrition, mental health, adolescents, dietary habits, mood stability.

Document Headings

The AMA manual does not specify exact formatting rules for headings. Instead, the emphasis is on maintaining consistency throughout the document while ensuring headings are clearly recognizeble.

For different heading levels:

  • Level 1 Headings: Can be either centered or left-aligned and may or may not be bolded.
  • Level 2 Headings: Should be left-aligned, either above the text or on the same line, and can be bolded, italicized, or presented without special formatting.
  • Level 3 Headings: Like Level 2, these should be left-aligned and can also be formatted in bold, italics, or remain unstyled.

Introduction
