The Concordance of Self-Report With Other Measures of Medication Adherence

Abstract

The concordance of self-report and other measures of medication adherence varies widely based on the type of measures used. Questionnaires and diaries tend to have moderate-to-high concordance with other measures of medication adherence. However, interview-based self-reports are not concordant with electronic measures. Questionnaire and diary methods could be preferable to interviews for self-reported medication adherence.

Integrating Support Persons into Diabetes Telemonitoring to Improve Self-Management and Medication Adherence

“…For data analysis, we stringently dichotomized patients' weekly reported adherence as "always" taking medication exactly as prescribed versus anything less than perfect adherence, which tends to correct for inflated adherence self-reporting. 22,23 In support of the validity of this method, we had previously found that the odds of nonadherence on this indicator doubled for each one-point increase in the MMAS total score. 10 Additional IVR items assessed patients' general health in the past week and other diabetes parameters such as self-monitoring of blood glucose and inspecting one's feet for tissue damage.…”

Potential Impact of Incorporating a Patient-Selected Support Person into mHealth for Depression

“…2,17 In a related issue, disclosure of problems might be inhibited if patients are uncomfortable with the automated interface or believe that denying problems will help abbreviate their IVR calls. Despite the fact that IVR assessment is a wellvalidated method for measuring depression symptoms, 23 follow-up studies should include confirmatory data sources such as electronic medication event monitoring, medical records, and corroboration from significant others.…”

“…We stringently dichotomized adherence as perfect versus less than perfect (another primary outcome), which tends to correct for inflated adherence self-reporting. 2,17 The IVR system also assessed functional impairment (the third primary outcome) by asking whether the patient had stayed in bed for any entire day during the past week due to mental health problems.…”

Antiplatelet Therapy Changes for Patients With Myocardial Infarction With Recurrent Ischemic Events: Insights Into Contemporary Practice From the TRANSLATE‐ACS (Treatment With ADP Receptor Inhibitors: Longitudinal Assessment of Treatment Patterns and Events After Acute Coronary Syndrome) Study

“…Routine platelet function testing is not recommended by consensus guidelines and is rare in clinical practice, and physicians infrequently change antiplatelet therapy in response to its results 1, 3, 32, 33. Medication nonadherence may play a role in physician decision making and is often underestimated with patient self‐reporting,34 but it was reported in only 5% of patients with recurrent ischemic events in our study. Approximately 12% of patients were not taking a P2Y 12 inhibitor at the time of their recurrent event, even though guidelines recommend 1 year of P2Y 12 inhibitor therapy after MI.…”
