  • Lists of stimulus materials
  • Instructions to participants
  • Tests, scales, or inventories developed for a study
  • Descriptions of complex equipment
  • Detailed or complex descriptions of items used to conduct a study
  • Appendices should be positioned at the end of the paper, after the references list
  • Each appendix should begin on a separate page 
  • Each appendix should have a label AND a title
  • If a paper has one appendix, label it Appendix
  • If a paper has more than one appendix (or appendices), label them in order using the letters of the alphabet: Appendix A, Appendix B, Appendix C, etc.
  • The appendix title should describe the contents of the appendix
  • Refer to the appendix using its label at least once within the paper
  • Format the contents of the appendices as per APA formatting guidelines
