Supplementing Your Article With Online Material

APA can place supplemental materials online, linked to the published article in the PsycARTICLES® database.

Examples of such material include

  • audio or video clips
  • oversized tables
  • lengthy appendixes
  • detailed intervention protocols
  • supplementary data sets

If you are interested in including such material with your article, please state your intentions in the cover letter that accompanies your submission to the Editor and include the material with your submission.

APA accepts two types of supplemental material. The first, defined as integral content, includes material that would be essential to the reader in understanding the article itself. The second, defined as additional content, is material that may be useful to the reader, but not essential to understanding the article.

Supplemental material that is defined as integral content by the author and/or journal Editor will be copyedited prior to publication. Please note that while some supplemental material may be integral to understanding the content of the article, the nature of the file type or material may prohibit it from being edited, for example, large data sets or audio/video files. Supplemental material defined as additional content will not be copyedited.

Provided the supplementary material is accepted for online publication, the final published version of the article will include a URL noting where the supplementary material can be found online. It is not necessary to refer to the supplementary material in the text of your manuscript, but you may do so if you wish.

Once accepted, all supplemental material is considered part of the journal's archival record and cannot be altered or removed.

Permissions May Be Required

Images of human subjects require the subjects' permission. Permission to reproduce such images, as well as any formerly published material, is required as a condition of acceptance of the article for publication in print and online. Failure to secure permissions will prevent APA from accepting the article for production.

Disclaimer

APA assumes no liability for errors or omissions in material that is not edited. The publisher reserves the right to refuse content considered to be obscene.
