AMA 11 Updates & Video

The Reference List

  • AMA Citation uses a NUMBERED Reference List
  • The Reference List is NOT Alphabetized
  • References are numbered consecutively in the order that they are cited in the text of the paper
    • For example, the first item in the Reference List should be 1.  This should also be the first item cited in the paper. 

AMA 11 How to...

General Guidelines for an AMA Paper

  • The AMA Manual of Style provides no specific preferences for font style or size; however, the following are good standards for a college-level paper  
  • Font: 12-Point Times New Roman is mentioned for easy readability
  • Double spaced
  • 1" margins
  • Title Page:
  • In center: Title of Paper, Name, College, Course # and Name, Instructor, Due Date
  • Page numbers in upper right corner
  • Section headings
  • References List (numbered, not alphabetical)
  • NOTE: A DOI (digital object identifier) is preferred over URL. If you use the DOI, you should NOT include the URL or date accessed. 
  • NOTE: If there is no date, put "date unknown" in place of the year
  • NOTE: To ensure you are following assignment guidelines, check with your professor.

The abstract and 3-10 key words should be included on the title page following the title, author and institution information.

Most often, you will be writing a literature review or reporting original data, and therefore will use a structured abstract, limited to 250 words, that uses predetermined headings.

The AMA handbook recommends use of the following:

  • Context
  • Evidence acquisition
  • Results
  • Conclusions

However, this is a common variation asked for by professors:

  • Objectives
  • Methodology and/or Research Design
  • Results (often reported quantitatively when appropriate)
  • Conclusions

Example:

Objective: To investigate the effect of music therapy on overall recovery time in pediatric patients post-operation. Methods: We used data collected from previous literature to compare recovery times in the population of interest. Results: Review of literature revealed a weak, negative correlation between exposure to music therapy and length of stay in recovery. Conclusion: While there appears to be a correlation between specialist administered music therapy and shorter recovery times in post-operation patients, more research is needed to objectively define any benefits such therapy can have in a pediatric population.

Key Words: music therapy, auditory therapy, pediatrics, post-operation recovery, length of stay.

Headings

AMA does not outline specifics requirements for typeface (e.g. boldface, italicized) or alignment (e.g centered, left-justified) of headings; as long as they are consistent within the paper and distinguishable from each other they will be acceptable.

Therefore:

  • Level 1 headings
    • May be centered or left-justified on the line above the text
    • May be bolded or not
  • Level 2 headings
    • Left-justified above the text or at the beginning of the text on the same line
    • May be bolded, italicized, or not
  • Level 3 headings
    • Left-justified above the text or at the beginning of the text on the same line
    • May be bolded, italicized, or not

Text

The main sections in an AMA literature review are often the same as those found in an APA paper (Introduction, Methods, Results, Discussion, etc.).

Introduction

This is where your background information goes. After informing the reader about your topic, this section should also present your research question and reason for your research. Include information about why this research is important and/or why it’s a problem, as well as how it ties to previous research in the field.

Methods

This section details how you conducted your research. You should outline databases (e.g., Ebsco Host, PubMed, etc.) filters (e.g., academic/peer-reviewed sources, date limitations, etc.), and keywords used in your searches and describe trends in the outcomes of these searches. This is also the section in which you should describe and justify your inclusion and exclusion criteria – i.e., the details of a study’s publication, design, or population that either allow it to be included or excluded from your research (e.g., “only studies published after 2005 were included” or “studies including participants over the age of 16 years were not considered”).

Results

In a report of original data, this section will most often summarize the collected data and include tables and figures used to analyze the results. If you are reporting on original research or quantitative data, this section will not provide any commentary or analysis of the results’ significance. In a literature review, this section will summarize and synthesize the major results and conclusions of the reviewed literature. It will often be structured with subheadings that organize your analysis by topic (e.g. “Music Therapy in Neurosurgery Recovery” or “Music Therapy in Addition to Pain Management via Pharmaceuticals”).

Discussion

The interpretation of your results goes here. Possible biases and/or weaknesses of the study or studies may be discussed, such as how sample demographics, study design, or reporting methods may have biased the results to a particular conclusion. You should also identify any gaps in the literature that may lead to potential for future research. In addition to this, your discussion section should describe the significance of your research to the greater body of knowledge or its role in solving the presented problem.

References

The heading for this section should be “References,” bolded and left-justified at the top of the next page. The references should then be numbered down the page in the order they appear in the text. References should not be double-spaced.

AMA 11 Citation Examples

Basic Format

Use Superscript numbers to show which Reference source is used.

Superscript numbers go AFTER periods and commas.

Superscript numbers go BEFORE colons and semicolons. 

Example with a period: Citing sources is difficult.1

Example with a semicolon: Citing sources is difficult1; if you follow the rules, it is easier. 

Citing Two or More Sources Sequentially

If using two or more sources that are sequential in reference number, type the range with a hyphen between the numbers. 

Example: It should be noted that proper usage of citations is crucial.1-3

Citing Two or More Sources Non-Sequentially

If using two or more sources that are non-sequential in reference number, place a comma without spaces between each number.

Example:  It should be noted that proper usage of citations is crucial and helpful to the reader.1-3,5

Citing Within a Sentence

If citing within a sentence, type the superscript number(s) after the word you wish to cite.  Use the rules listed above for typing superscript numbers. 

Example: Citations are academically honest2 and useful when proving3-4 your point. 

Citing an Author or Multiple Authors

If citing one author, only use the last name followed by the superscript 

Example: Jonesstated that citation is necessary for publication. 

If citing two authors, use the last names of both authors and place the superscript at the end of the second author's name

Example: Jones and Smith2 reported that publishing academic papers is difficult. 

If citing more than two authors, use the first author's last name and "et al." The superscript goes at the end of et al 

Example: Jones et al3 noted that sometimes three can be a crowd. 

Citing the Same Source with Different Page

If you need to cite the same source but using different pages throughout the paper, use the original Reference List number superscript with page number(s) listed in the superscript

  • Examples: 
    • Original source 1: Winters1

    • Original source 1 using page 21: Winters1(p21)

    • Original source 1 using page numbers 21-24: Winters1(pp21-24)

    • Original source 1 using page numbers 21-24 AND sources 9 and 10 from the Reference List: Winters1(pp21-24),9,10

Minimal Acceptable Data for References

  • AMA has different citation templates for different formats of References
    • Journal Article vs. Book vs. Website
  • AMA calls these templates "Minimal Acceptable Data for References" 
  • Journal Articles
    • Print
      • Author(s). Article title. Abbreviated Journal Name. Year;volume(Issue number):inclusive pages. DOI (if provided)
    • Online 
      • Author(s). Article title. Abbreviated Journal Name. Publication date. DOI (if provided)

    • Author (if no author is available, use the name of the organization responsible for the site). Title (if no title is available, the name of the organization responsible for the site). Name of the website. Published [date]. Updated [date]. Accessed [date]. URL. 

*A DOI is always preferred if provided. Do not use a period after a DOI (this might alter the accuracy of the DOI)

Authors

  • Authors are listed by Last Name First Initial
  • There are no commas between Last Name and First Initial
  • John Smith would be written as Smith J. 
  • For 2-6 authors, list all authors as above without using "and" in the string of names and placing a comma between authors
  • For more than 6 authors, list the first 3 authors and follow with "et al" (not in quotations)
    • For example, here is an article with 8 authors, list the authors as:
      • Smith J, Michaels M, Jones P, et al. 
  • If no author is listed, use the article title or book title as the author

Reference Item Titles (Article titles and Book chapters)

  • For Journal Article titles:
    • Do not italicize or place in quotations
    • Only capitalize the first letter of the first word and any words that are normally capitalized
      • Also capitalize the first letter of the first word of a subtitle
      • Example: Anatomy of the arm shows little ability to survive extreme cold: A literature review. 
        • The "A" in Anatomy and the "A" of the subtitle are capitalized
  • For Book Chapter titles:
    • Use the same rules as Journal Article titles above

Reference Format Titles (Journal Titles and Book Titles)

  • Reference format titles, such as the title of an academic journal, are treated differently in AMA than other citation styles
  • Academic Journals: 
  • Books, Government Bulletins, Documents, and Pamphlets:
    • Capitalize the first letter of each major word
      • EXCEPT: articles, prepositions of 3 or fewer letters (as, of, per)
    • The title is in italics
