Lawyers representing the purported owner of the Morisky Medication Adherence Scale (both MMAS-4 and MMAS-8), and one of its authors, Dr. Donald Morisky, have threatened universities and researchers with copyright infringement and breach of contract lawsuits, and pushed for retraction of publications, when a researcher has used either MMAS-4 or MMAS-8 as part of academic research. The University of Illinois Office of University Counsel’s (OUC) current advice is not to sign any license, permission, or other document that MMAS Research, LLC, Dr. Morisky, or his associate Mr. Steven Trubow, might send to you in connection with the MMAS-4 or MMAS-8, and forward the document to Sponsored Programs Administration (SPA). If you are contacted directly by Dr. Morisky, Mr. Trubow, or one of their lawyers asserting that you may have violated a law or contract, please contact OUC. OUC also urges you to consider using (or, if protected by copyright, requesting permission to use) a publicly available alternative to the MMAS-4 or MMAS-8 as part of any research involving medication adherence. For example, researchers at peer universities are now using NIH-funded Self-Reported Medication Nonadherence measurement tools created by Corrine Voils, PhD, available here, as alternatives to MMAS-4 or MMAS-8.
You may also want to consider using, or requesting permission to use, one or more of the following, instead of the MMAS-4 and MMAS-8: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4656225/table/Tab2/?report=objectonly.
