TL;DR: This article stems from the International Society of Pharmacoeconomics and Outcomes Research efforts to develop a checklist of items that should be either included, or at least considered, when a retrospective database analysis of medication compliance or persistence is undertaken, to improve the consistency and quality of C&P analyses.

TL;DR: The concordance of self-report and other measures of medication adherence varies widely based on the type of measures used, and questionnaires and diaries tend to have moderate-to-high concordant with other measuresof medication adherence.

TL;DR: Patients given maintenance antidepressants vary widely in adherence, primarily explained by the balance between their perceptions of need and harmfulness of antidepressant medication, in that adherence is lowest when perceived harm exceeds perceived need, and highest when perceived need exceeds perceived harm.

TL;DR: Investigation of the mediating role of patients' beliefs about diabetes and diabetes medications in relation to depressive symptoms and diabetes medication adherence found reduced self-efficacy and heightened perceived barriers had a negative association with patients' adherence to diabetes medication regimens.

TL;DR: The accordance between a Morisky-type adherence scale and measures of missed doses is unsatisfactory, however, “missed-dose” measures using two-day or two-week time periods yield fairly similar results.
