Glossary of Lay Terms for Use in Informed Consent Forms

According to federal guidelines, language in Informed Consent Forms should be suitable for subjects, which is generally interpreted to mean language at the 8th grade level. The definitions below are intended to help Principal Investigators with this process.

A very good source for simplified explanations of medical procedures and equipment is MedLine Plus: http://www.nlm.nih.gov/medlineplus/.

Please send any comments or suggestions to ufirb-l@lists.ufl.edu
