About AMA Style

AMA stands for the American Medical Association. It is a formatting and referencing style commonly used in health sciences fields, such as Health and Human Performance. 

AMA Quick Tips

  • AMA references should be listed in the order they were used in your paper, not alphabetical order.
  • Unpublished materials should be cited in-text, but should not appear in your references section.
  • Each reference number should correspond to a single source.
  • AMA is sometimes referred to as JAMA (The Journal of the American Medical Association). If you're using a citation management tool and don't see AMA listed, check for JAMA.
  • When citing a source with more than six authors, list the first three followed by "et al."
