Abstract
Medication adherence plays an important role in optimizing the outcomes of many treatment and preventive regimens in chronic illness. Self-report is the most common method for assessing adherence behavior in research and clinical care, but there are questions about its validity and precision. The NIH Adherence Network assembled a panel of adherence research experts working across various chronic illnesses to review self-report medication adherence measures and research on their validity. Self-report medication adherence measures vary substantially in their question phrasing, recall periods, and response items. Self-reports tend to overestimate adherence behavior compared with other assessment methods and generally have high specificity but low sensitivity. Most evidence indicates that self-report adherence measures show moderate correspondence to other adherence measures and can significantly predict clinical outcomes. The quality of self-report adherence measures may be enhanced through efforts to use validated scales, assess the proper construct, improve estimation, facilitate recall, reduce social desirability bias, and employ technologic delivery. Self-report medication adherence measures can provide actionable information despite their limitations. They are preferred when speed, efficiency, and low-cost measures are required, as is often the case in clinical care.

We conducted four rounds of cognitive testing of self-report items that included 66 sociodemographically diverse participants, then field tested the three best items from the cognitive testing in a clinic waiting room (N = 351) and in an online social networking site for men who have sex with men (N = 6,485). As part of the online survey we conducted a randomized assessment of two versions of the adherence questionnaire鈥攐ne which asked about adherence to a specific antiretroviral medication, and...

In medication adherence-promotion trials, participants in the intervention arm are often cognizant of the researcher鈥檚 aim to improve adherence; this may lead to their inflating reports of their own adherence compared to control arm participants. Using data from 1,247 HIV-positive participants across eight U.S. Studies in the Multi-site Adherence Collaboration on HIV (MACH14) collaboration, we evaluated the validity of self-reported adherence by examining whether its association with two more ob...

Aims Medication non-adherence is a significant health problem. There are numerous methods for measuring adherence, but no single method performs well on all criteria. The purpose of this systematic review is to (i) identify self-report medication adherence scales that have been correlated with comparison measures of medication-taking behaviour, (ii) assess how these scales measure adherence and (iii) explore how these adherence scales have been validated. Methods Cinahl and PubMed databases were...

Poor adherence to antiretroviral therapy (ART) contributes to disease progression and emergence of drug-resistant HIV in youth with perinatally acquired HIV infection (PHIV +), necessitating reliable measures of adherence. Although electronic monitoring devices have often been considered the gold-standard assessment in HIV research, they are costly, can overestimate nonadherence and are not practical for routine care. Thus, the development of valid, easily administered self-report adherence meas...

Background Hospitalization contributes enormously to health care costs associated with heart failure. Many investigators have attempted to predict hospitalization in these patients. None of these models has been highly effective in prediction, suggesting that important risk factors remain unidentified.

OBJECTIVE To assess the validity of self-report measures of diabetes medication adherence and evaluate the effect of depression on the validity of these reports. RESEARCH DESIGN AND METHODS Adults with type 2 diabetes, treated with oral medications, completed a set of medication adherence self-reports that varied response scales and time frames, were administered structured clinical interviews for depression, and provided blood samples for HbA 1c as part of a screening for an intervention study....

A decade after widespread recognition that adherence to medication regimens is key to antiretroviral effectiveness, considerable controversy remains regarding a 鈥済old standard鈥 for adherence measurement. Each adherence measurement approach has strengths and weaknesses and each rests on specific assumptions. The range of assumptions regarding adherence measurement and the diversity with which each approach is implemented strongly suggest that the evaluation of a particular measure outside of the ...

The relationship between adherence to antiretroviral therapy (ART) and virologic outcomes in HIV+ children, adolescents, and young adults has been notably understudied, with much of the extant research focused on specific sub-literatures, such as resource-limited regions, specific clinical outcomes and time frames. The authors sought to better characterize the relationship between adherence to ART and virologic functioning along various sample and methodological factors. The authors conducted a ...

The self-rating scale item (SRSI) is a single-item self-report adherence measure that uses adjectives in a 5-point Likert scale, from 鈥渧ery poor鈥 to 鈥渆xcellent,鈥 to describe medication adherence over the past 4 weeks. This study investigated the SRSI in 2,399 HIV-infected patients in routine care at two outpatient primary HIV clinics. Correlations between the SRSI and four commonly used adherence items ranged from 0.37 to 0.64. Correlations of adherence barriers, such as depression and substance...

Abstract Background: Little is known regarding the degree to which substance and alcohol use effects on HIV viral suppression are mediated through medication adherence. We hypothesized that the total effects of such use are mediated through adherence. Methods: We included patients with HIV (PWH) receiving care at an urban academic HIV clinic between 2014 and 2018. Eligible patients were those prescribed antiretroviral therapy who completed both patient reported outcome (PRO) questionnaires, and ...

Background: Medication non-adherence is a complex multifactorial phenomenon impacting patients with various health conditions worldwide. Therefore, its detection can improve patient outcomes and minimize the risk of adverse consequences. Even though multiple self-reported medication adherence assessment scales are available, very few of them exist in Arabic language. Therefore, the aim of this study was to validate a newly translated Arabic version of the Adherence to Refills and Medications Sca...

Introduction null Substantial improvements in viral suppression among people living with HIV (PLHIV) are needed to end the HIV epidemic, requiring extensive scale-up of low-cost HIV monitoring services. Point-of-care (POC) tests for monitoring antiretroviral therapy (ART) adherence and viral load (VL) may be efficient and effective tools for real-time clinical decision making. We aim to evaluate the effects of a combined intervention of POC ART adherence and VL testing compared with standard-of-...

Understanding factors related to suboptimal adherence to antiretroviral therapy (ART) and detectable viral load (VL), especially among vulnerable populations, is needed to improve HIV outcomes. The Caribbean is highly impacted by HIV and socioeconomic inequalities, but few studies have been conducted there to explore food insecurity among people with HIV and factors associated with viral suppression in this vulnerable population. Using baseline data from a pilot intervention trial among people l...

Purpose Patient adherence to wearing compression stockings in the management of chronic venous insufficiency (CVI) and venous leg ulcers (VLUs) is low. Poor adherence with compression stockings contributes to recurrence and impaired healing of VLUs. As such, the purpose of this review was to report on the scientific evidence related to adherence and explore modifiable factors which impact adherence with compression stockings. Methods A systematic search was conducted from inception to 31 October...
