To stimulate research and evaluation on issues related to medication adherence, treatment persistence, and implications for health outcomes.


Medication non-adherence has a significant impact on patients’ morbidity and mortality. Behavioral interventions have been developed to improve medication adherence. Adherence research requires an understanding about the best methodology to conduct studies especially when assessing interventions. Adherence studies include various designs such as: randomized controlled clinical trials, observational, and quasi-experimental studies. The Medication Adherence and Persistence Special Interest Group will develop good research practice recommendations for the conduct of medication adherence and treatment persistence research studies and will provide insight, through systematic reviews of the medication adherence literature, on interventions that improve medication adherence.
