The impact of symptom clusters on endocrine therapy adherence in patients with breast cancer

BackgroundWhen taken as prescribed, endocrine therapy is effective in reducing risk of recurrence and mortality in the treatment of patients with breast cancer. However, treatment side effects can act as a barrier to medication adherence. Existing research has not identified any specific side effects as consistent predictors of nonadherence. Our aim was to explore the influence of symptom clusters on self-reported adherence in patients with breast cancer. MethodsA cross-sectional online survey was conducted, including patients with breast cancer currently or previously prescribed endocrine therapy (N = 1051). This included measures of self-reported endocrine therapy adherence and common symptoms among this population (insomnia, depression, anxiety, fatigue, musculoskeletal, and vasomotor symptoms). ResultsUnintentional nonadherence was higher than intentional nonadherence (50.8 % vs 31.01 %). The most troublesome symptom was insomnia (73.83 % displayed probable insomnia disorder). K-means cluster analysis identified 2 symptom clusters: overall High symptoms, and overall Low symptoms. Participants in the Low symptoms cluster were significantly more likely to be classed as adherent based on unintentional and intentional items. ConclusionsNonadherence was high in the current sample, and significantly more likely in participants reporting overall severe symptoms. Clinicians should be aware of the scale of common side effects and facilitate open conversation about potential barriers to adherence. Follow-up care should include assessment of common symptoms and signpost patients to appropriate support or treatment when required. Future research should explore potential for a central symptom to act as a target for intervention, to relieve overall side effect burden and facilitate better medication adherence.

Assessing the Self-Rating Scale Item as a Measure for Lactulose Adherence

Background/Objective:Hepatic encephalopathy (HE) is a defining complication of end-stage liver disease. The standard treatment is lactulose, but adherence is difficult due to complex dosing regimens and side effects. We adapted a single item self-reported adherence measure - the Self Rating Scale Item (SRSI) - for lactulose use and examined its relationship with clinical events, cognition, and quality of life.
 Methods:We performed a cross-sectional study of patients with cirrhosis and HE seen at Indiana University Hospital 5/31/2023-7/14/2023. Clinical history and demographic information were collected through electronic health records and patient interviews. Patients provided the SRSI, which reflects their self-perceived ability to take lactulose, bowel movement frequency, perception of missing doses, and quality of life (PROMIS-29+2). Cognition was measured using the Animal Naming Test (ANT). The relationship between the SRSI and other measures was assessed.
 Results:42 patients met eligibility criteria and enrolled. The median age was 59, and 55% were female. Patients were divided across SRSI categories: ≤good, very good, and excellent. Patients with better adherence were more likely to have ascites, but other demographics were similar between groups. Ascites was present in 43%, 64%, and 93% of ≤good, very good, and excellent categories, respectively. A higher SRSI score was associated with fewer missed doses and more days achieving bowel movement targets. 79% in the ≤good category skipped lactulose doses compared to 29% and 21% in very good and excellent groups. SRSI was not associated with HE-related hospitalizations or ANT. Higher SRSI was associated with improved sleep and cognitive function, with a trend towards decreased fatigue and pain.
 Conclusion/Potential Impact:The SRSI is associated with other measures of lactulose adherence and quality of life and may be a promising tool to measure lactulose adherence. Adopting the SRSI may be a useful way to improve lactulose dosing, adherence, and health outcomes.

Validity, sensitivity and specificity of a measure of medication adherence instrument among patients taking oral anticoagulants.

Although self-report instruments are currently considered a valuable tool for measuring adherence, due to their low cost and ease of implementation, there are still important factors that impact measurement accuracy, such as social desirability and memory bias. Thus, the Global Assessment of Medication Adherence Instrument (GEMA) was developed to provide an accurate measure of this construct. The aim of this study was to evaluate the properties of the measurement of the Global Evaluation of Medication Adherence Instrument (GEMA) among patients with chronic diseases. A methodological study was conducted in the public hospital of the state of São Paulo, Brazil. The adherence to anticoagulants as well as the international normalized ratio (INR) was assessed on 127 patients. Besides GEMA, two other instruments were used to assess adherence: the Morisky Medication Adherence Scale-8 (MMAS-8) and the Measurement of Adhesion to Treatments (MAT). The GEMA presented a satisfactory level of specificity (0.76) to identify adherents among those with a stable INR, low sensitivity (0.43) for the identification of non-adherents among those with an unstable INR, and a Positive Predictive Value of 0.70. Positive and weak to moderate correlations were observed between the proportion of doses assessed with GEMA and the scores on the MMAS-8 (r = .26 and r = .22, respectively) and the MAT (r = .22 and r = .30, respectively). The GEMA presented good practicality, acceptability, and evidence of specificity regarding the stability of the INR. The validity of the construct was partially supported by the relationship with self-reported measures of adherence.

Implementing a self-reported immunosuppression adherence questionnaire to screen for non-adherence in routine care of kidney transplant recipients.

Self-reported measures of immunosuppression adherence have been largely examined in research settings. In this single center study of 610 kidney transplant recipients, we examined if a voluntary, non-anonymous self-report measure could identify non-adherence in a routine clinic setting and how patients perceived such a measure. Non-adherence was measured using the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS) and patient perception was elicited using a customized questionnaire. Non-responders to the survey (15%) were younger, more likely to be black, and less likely to have had a pre-emptive transplant. Among complete responders (n=485), 38% reported non-adherence with non-adherent patients being younger (54y vs. 60y; p=.01), less likely to have been on dialysis pre-transplant (59%vs. 68%; p=.04), further out from transplant (37vs. 22 months; p<.001) and had more rejections in the preceding year (8%vs. 3%; p=.02). Self-reported non-adherence was associated with higher calcineurin inhibitor intra-patient variability (27.4%vs. 24.5%; p=.02), but not with donor-specific antibody detection (27.8%vs. 21.2%, p=.15). Of patients providing feedback (n=500), the majority of patients felt comfortable reporting adherence (92%), that the survey was relevant to their visit (71%), and that the survey did not interfere with their clinic visit (88%). In summary, a self-reported questionnaire during clinic visits identified immunosuppression non-adherence in a significant proportion of patients and was well received by patients. Integrating self-report measures into routine post-transplant care may enable early identification of non-adherence.

Psychometrics and applications of a novel self-report measure of emicizumab adherence: VERITASNexGen.

Treatment adherence is critical to minimize bleeding episodes in persons with haemophilia. Suboptimal adherence increases risk of adverse medical outcomes and negatively impacts quality of life. Assessment of treatment adherence is therefore an integral component of intervention to mitigate the adverse impacts of haemophilia. To develop and validate a multifactorial, patient (self or caregiver) report adherence measure for emicizumab treatment and report the first patient-report data on adherence to specific components of emicizumab treatment (dosing, timing, injection, planning and bleeds). An IRB approved multi-site prospective study enrolled 83 participants with factor VIII deficiency being treated with emicizumab. Participants completed the 25-item VERITAS NexGen (self-report from 50 adults age 18+ years; caregiver-report from 33 parents of children aged 6months to 17years) as well as a global adherence rating (GAR) scale. Providers of participants also completed a GAR scale. Most VERITAS-NexGen subscales had good-to-excellent internal consistency reliability, test-retest reliability, and validity. VERITASNexGen scores revealed globally strong patient-reported adherence; however timing and bleed management were reported as greater challenges to adherence compared to dosing and injections. Adults struggled more with timing and planning of injections than caregivers. The VERITASNexGen is the first validated multifactorial patient-report measure of adherence designed specifically for emicizumab treatment. Results suggest excellent adherence, with only 4%-13% of participants reporting suboptimal adherence to different components of the treatment regimen. Used in conjunction with other adherence measures, VERITAS-NexGen meets a crucial need for monitoring and understanding patient adherence to emicizumab in clinical and research settings.

Depression-Mediating Pathways From Household Adversity to Antiretroviral Therapy Nonadherence Among Children and Adolescents Living With HIV in Zambia: A Structural Equation Modeling Approach.

In Zambia, half of children and adolescents living with HIV (CALWH) on antiretroviral therapy (ART) are virologically unsuppressed. Depressive symptoms are associated with ART nonadherence but have received insufficient attention as mediating factors in the relationship between HIV self-management and household-level adversities. We aimed to quantify theorized pathways from indicators of household adversity to ART adherence, partially mediated by depressive symptoms, among CALWH in 2 Zambian provinces. In July-September 2017, we enrolled 544 CALWH aged 5-17 years and their adult caregivers into a year-long prospective cohort study. At baseline, CALWH-caregiver dyads completed an interviewer-administered questionnaire, which included validated measures of recent (past 6 months) depressive symptomatology and self-reported past-month ART adherence (never versus sometimes or often missing medication doses). We used structural equation modeling with theta parameterization to identify statistically significant ( P < 0.05) pathways from household adversities (past-month food insecurity and caregiver self-reported health) to depression (modeled latently), ART adherence, and poor physical health in the past 2 weeks. Most CALWH (mean age: 11 years, 59% female) exhibited depressive symptomatology (81%). In our structural equation model, food insecurity significantly predicted elevated depressive symptomatology ( ß = 0.128), which was associated inversely with daily ART adherence ( ß = -0.249) and positively with poor physical health ( ß = 0.359). Neither food insecurity nor poor caregiver health was directly associated with ART nonadherence or poor physical health. Using structural equation modeling, we found that depressive symptomatology fully mediated the relationship between food insecurity, ART nonadherence, and poor health among CALWH.

P084 The relationship between self-reported adherence, drug levels and tumour necrosis factor inhibitor response in psoriatic arthritis

Abstract Background/Aims It is not currently possible to accurately predict tumour necrosis factor inhibitor (TNF-i) response in psoriatic arthritis (PsA). In rheumatoid arthritis, suboptimal adherence to TNF-i and reduced drug levels have been associated with decreased response. Suboptimal treatment adherence (16%-81%) has been reported in PsA although little is known about the impact on TNF-i response. Self-reported adherence may be biased, but direct drug measurements offer an objective adherence evaluation. The objective of this study is to assess the relationship between self-reported adherence, drug levels, and drug response to TNF-i in PsA. Methods Blood samples and adherence questionnaires were collected at 3, 6 and 12 months for PsA patients prescribed biologic or targeted synthetic anti-rheumatic drugs in a UK multi-centre observational study (OUTPASS). Self-reported adherence was measured using two previously validated questionnaires (MARS5 and Treatment). Adherence was classified as self-reporting never missing or delaying a dose, unless medically advised. Adalimumab (ADA) and etanercept (ETN) drug levels were measured at 3 and 6 months using commercially available ELISAs. Clinical response was assessed using PsARC and ΔDAS28 between baseline and 3, 6 and 12 months. Univariate regression and general estimating equations were used to assess associations across timepoints. Results In the OUTPASS cohort (46% ADA, 40% ETN), 42% of patients self-reported non-adherence within the first 12 months of treatment. Patients with self-reported non-adherence at 6 months using the MARS5 questionnaire were significantly less likely to achieve a PsARC response at 6 months [odds ratio (OR)=0.40, P = 0.047] in univariate regression. Non-adherence, reported using the Treatment questionnaire, was associated with decreased PsARC response over 12 months [OR = 0.52, P = 0.031]. There was no association (P &amp;gt; 0.05) between whether a patient returned a self-reported adherence questionnaire and response. Drug levels at 3 months (n = 70 (ADA), 73 (ETN)) were associated with drug levels at 6 months (n = 61 (ADA), 67 (ETN)) for both ADA [β = 0.47, P = 0.001] and ETN [β = 0.41, P = 0.018] paired samples. Higher 3-month ADA levels were associated with increased ΔDAS28 response at 3 months [β = 0.11, P = 0.036] and PsARC response at 12 months [OR = 1.39, P = 0.028]. Higher 3-month ETN levels were associated with increased PsARC response at 3 months [OR = 1.50, P = 0.026]. Increased ADA levels were associated with improved ΔDAS28 over 12 months [β = 0.07, P = 0.001] and higher ETN levels associated with enhanced PsARC response [OR = 1.17, P = 0.022] over 12 months. Levels of neither drug were associated (P &amp;gt; 0.05) with any self-reported adherence measures at any time point. Conclusion There was no association between self-reported adherence and TNF-i drug levels in ADA or ETN-treated PsA patients. Objectively measured adherence via drug level measurements were more strongly associated with drug response than self-reported measures, particularly using ΔDAS28 as the measure of response.

Exploring Self-reported Adherence Measures to Screen for Elevated HIV Viral Load in Adolescents: A South African Cohort Study

The timely identification of ART non-adherence among adolescents living with HIV presents a significant challenge, particularly in resource-limited settings where virologic monitoring is suboptimal. Using South African adolescent cohort data (N = 933, mean age 13.6 ± 2.89 years, 55.1% female, follow-up = 2014–2018), we examined the association between elevated viral load (VL ≥ 1000 copies/mL) and seven self-reported adherence measures on missed doses, and clinic appointments –with varying recall timeframes. The best performing measures, which were significantly associated with elevated viral load in covariate-adjusted models are: any missed dose –past 3 days (sensitivity = 91.6% [95%CI: 90.3–92.8], positive predictive value (PPV) = 78.8% [95%CI: 77.2–80.4]), –past week (sensitivity = 87% [95%CI: 85.4–88.6], PPV = 78.2% [95%CI: 76.5–79.9]), –past month (sensitivity = 79.5% [95%CI: 77.5–81.4], PPV = 78.2% [95%CI: 76.4–79.9]), any past-month days missed (sensitivity = 86.7% [95%CI: 85.1–88.3], PPV = 77.9% [95%CI:76.2–79.6]), and any missed clinic appointment (sensitivity = 88.3% [95%CI: 86.8–89.8], PPV = 78.4% [95%CI: 76.8–79.9]). Combining the three best performing measures missed dose –past 3 days, –past week, and any past-year missed clinic appointment increased sensitivity to 96.4% while maintaining a PPV of about 78%. The discriminatory power of simple and easy-to-administer self-reported adherence measures in detecting elevated viral load warrants consideration in resource-limited settings and may contribute to the aims of the new Global Alliance to End AIDS in children and adolescents by 2030.

Using the integrated theory of health behavior change to assess factors affecting diabetes medication adherence among black adults during COVID-19: an explanatory sequential mixed methods design

ABSTRACT Objectives (1) Evaluate changes in medication adherence and the role of psychosocial and interpersonal factors on adherence. (2) Explain the changes in medication adherence based on patient perceptions of adherence behaviors. Design We used an explanatory sequential mixed methods design for surveys at baseline and 1-year follow-up, followed by interviews. The Integrated Theory of Health Behavior Change guided the design of a questionnaire including self-reported measures of medication adherence, psychosocial factors such as illness and medication beliefs, self-efficacy, and depressive symptoms, interpersonal factors including social support and patient-provider communication, and socio-demographic and clinical factors. A convenience sample (n = 228) of adult patients with type 2 diabetes who self-identified as Black/African American completed the mail/telephone surveys. Nine semi-structured interviews were conducted with respondents of both surveys who had changes in medication adherence. Descriptive, mean differential, bivariate correlational analyses, and content analysis was conducted. Data integration merged quantitative and qualitative results as a joint display. Results Response rates for the baseline and follow-up survey were 28% and 47% respectively. Medication adherence scores were significantly correlated with illness perceptions (r = .30) and depression (r = .25) at baseline, and self-efficacy (r = −.51) and depression (r = .37) at follow-up. Qualitative themes included patient perceptions of adherence behaviors, impact of the COVID-19 pandemic, health literacy and self-efficacy. Mixed methods integration showed contrasting perceptions of the same themes including adherence behaviors, medication beliefs, social support, and patient-provider communication among participants whose medication adherence increased and decreased overtime. Conclusion Self-efficacy, diabetes beliefs, and depressive symptoms were key psychosocial factors that affected medication adherence among Blacks/African Americans. Contrasting perceptions of beliefs in medicines, social support, provider relationships and communication among increased and decreased adherence participant groups explained the changes in adherence, which can be used to adapt existing interventions.

Predictors of adherence to controller medication in urban African American emerging adults with uncontrolled persistent asthma

Background African American emerging adults tend to have low adherence to asthma controller medication, as well as a disproportionate burden of asthma morbidity and mortality. This study explored constructs from the Information-Motivation-Behavioral Skills model as predictors of controller medication adherence in urban African Americans ages 18–29 (N=152) with uncontrolled asthma using multiple measures of self-reported adherence. Methods Structural equation modeling (SEM) was employed to test the hypothesized mediation model that specified the relationship among psychological distress, substance use, asthma knowledge, motivation, self-efficacy, and adherence. Results Results suggested that motivation is an important predictor of adherence to medication; moreover, higher self-efficacy was associated with higher motivation. Results also highlighted psychological distress as an important intervention target to improve medication adherence in emerging adults. Conclusions The model tested in this study may offer a feasible framework for beginning to understand adherence to controller medication in this population.

Adaptive Goal Processes and Underlying Motives That Sustain Mental Wellbeing and New Year Exercise Resolutions.

Exercise resolutions are the most common goals people set each New Year. However, research has rarely examined adaptive goal processes and motives that may maintain wellbeing and resolution pursuit. We therefore investigated if (1) personal goal flexibility and tenacity maintain mental wellbeing and adherence to New Year exercise resolutions and if (2) underlying intrinsic and extrinsic motives maintain wellbeing and sustained exercise resolution adherence. A community sample (N = 297) completed an online longitudinal study. At baseline, participants listed their most important exercise-related New Year resolution. Participants then completed measures to assess goal flexibility and tenacity, resolution motives, and mental wellbeing at baseline. At three follow-up surveys over a two-month period, participants completed self-report measures of wellbeing and adherence to their exercise resolution. As predicted, goal flexibility and tenacity each independently predicted wellbeing across time. Counter to prediction, neither goal flexibility nor tenacity predicted sustained exercise adherence. Notably, underlying intrinsic motives (but not extrinsic motives) maintained mental wellbeing and exercise adherence across time. Our findings indicate that goal flexibility and tenacity are beneficial in maintaining mental wellbeing and that pursuing resolutions for internalised motives is beneficial for one's mental wellbeing and exercise adherence.

Adherence monitoring methods to measure virological failure in people living with HIV on long-term antiretroviral therapy in Uganda.

Appointment keeping and self-report within 7-day or and 30-days recall periods are non-objective measures of antiretroviral treatment (ART) adherence. We assessed incidence of virological failure (VF), predictive performance and associations of these adherence measures with VF among adults on long-term ART. Data for persons initiated on ART between April 2004 and April 2005, enrolled in a long-term ART cohort at 10-years on ART (baseline) and followed until December 2021 was analyzed. VF was defined as two consecutives viral loads ≥1000 copies/ml at least within 3-months after enhanced adherence counselling. We estimated VF incidence using Kaplan-Meier and Cox-proportional hazards regression for associations between each adherence measure (analyzed as time-dependent annual values) and VF. The predictive performance of appointment keeping and self-reporting for identifying VF was assessed using receiver operating characteristic curves and reported as area under the curve (AUC). We included 900 of 1,000 participants without VF at baseline: median age was 47 years (Interquartile range: 41-51), 60% were women and 88% were virally suppressed. ART adherence was ≥95% for all three adherence measures. Twenty-one VF cases were observed with an incidence rate of 4.37 per 1000 person-years and incidence risk of 2.4% (95% CI: 1.6%-3.7%) over the 5-years of follow-up. Only 30-day self-report measure was associated with lower risk of VF, adjusted hazard ratio (aHR) = 0.14, 95% CI:0.05-0.37). Baseline CD4 count ≥200cells/ml was associated with lower VF for all adherence measures. The 30-day self-report measure demonstrated the highest predictive performance for VF (AUC = 0.751) compared to appointment keeping (AUC = 0.674), and 7-day self-report (AUC = 0.687). The incidence of virological failure in this study cohort was low. Whilst 30- day self-report was predictive, appointment keeping and 7-day self-reported adherence measures had low predictive performance in identifying VF. Viral load monitoring remains the gold standard for adherence monitoring and confirming HIV treatment response.

Exploring the Agreement Between Self-Reported Medication Adherence and Pharmacy Refill-Based Measures in Patients with Kidney Disease.

To assess the quantitative and categorical agreement between two methods of measuring medication adherence: pharmacy refill-based medication possession rates and self-reported medication adherence scale. Categorisation of adherence metrics using empirical cut-off scores can lead to misclassification, which can be overcome by expressing adherence as a continuous variable. Pharmacy refill-based adherence can be reported as actual rates, but the validity of expressing self-reported medication adherence scores as a continuous variable to reflect adherence is unknown and its quantitative agreement with refill-based adherence rates untested. Patients with kidney disease, including dialysis patients, from Illawarra Shoalhaven region of New South Wales, Australia were recruited between January 2015 and June 2016 to this cross-sectional study. Medication adherence was assessed using the self-reported Morisky Medication Adherence Scale (MMAS) and two pharmacy refill-based measures, Medication Possession Ratio (MPR) and Proportion of Days Covered (PDC) for antihypertensives and cardiometabolic drugs. Categorical and quantitative agreement between self-reported adherence and pharmacy refill-based adherence were assessed using tests of trend, analysis of covariance (ANCOVA), Cohen's kappa and Bland-Altman analysis. We recruited 113 patients. There was a significant declining trend of MPR (p < 0.001) and PDC (<0.001 for antihypertensives, p = 0.004 for cardiometabolic) scores among categories with worsening MMAS adherence. Adjusted ANCOVA showed significant association between self-report and pharmacy refill-based adherence (p < 0.001). Weighted Cohen's kappa statistics showed fair agreement between the self-report and pharmacy refill-based categories. Bland-Altman's analysis showed less than 5% of cases were outside the limits of agreement (-0.36 to 0.27) and the bias for MMAS was negative (-0.05 to -0.09), indicating MMAS did not overestimate adherence. There is modest agreement between pharmacy refill-based measures and self-report MMAS measures when assessed categorically or quantitatively. Assessing adherence as a continuous variable should be considered to overcome the challenges associated with categorization of adherence based on arbitrary thresholds.

Self-reported and pill count measures of adherence to oral HIV PrEP among female sex workers living in South-Western Uganda.

Female sex workers (FSWs) in Uganda are at high risk of HIV infection. Scaling up oral pre-exposure prophylaxis (PrEP) will reduce HIV incidence if high levels of adherence are maintained. This study evaluates PrEP adherence using clinic-based pill counts and self-reported measures, and factors associated with protective levels of adherence. Participants were sex workers who had been taking PrEP for at least 5 months and were attending routine follow-up visits for PrEP care in fishing communities and along the Trans-African Highway. Participants who had a pill count showing at least 85% use since their last clinic visit and those who reported taking their PrEP every day in the last 5 months were categorised as having 'protective adherence'. Spearman's correlation and weighted kappa assessed the relationship between pill count and self-reported measures. Bivariate and multivariate logistic regression was used to determine factors associated with protective adherence as measured by pill count. We recruited 524 FSWs, with a median age of 29 years (IQR 23-35). Participants were recruited from fishing communities and Trans-African Highway towns (n = 297, 56.7%, and n = 227, 43.0%). Nearly three quarters (n = 372, 71.0%) of women were estimated to have protective adherence based on pill count (i.e., a pill count of &gt;85%) and 50.4% by self-report in last 3 months. There was a strong positive association between self-reported measures and pill count measures (rest = 0.6453, 95% CI = 0.5924-0.6927) and a moderate agreement between self-reported measures and pill count measures, κ = 0.544 (95%CI = 0.4869-0.6011, p &lt; 0.001). Factors associated with protective adherence included being aged 35 years or older (aOR = 2.40, 95% CI = 1.17-4.86), living in a fishing community (aOR = 1.45, 95% CI = 0.62-3.38), and having an STI in last 3 months (aOR = 1.64, 95% CI = 1.07-2.49). Our findings indicate that PrEP-experienced FSWs attending clinical follow-up visits reported high protective levels of oral pre-exposure prophylaxis, as measured by both pill count and self-reported measures, and a moderate agreement between pill count and self-reported measures.

Is self-reported adherence a valid measure of glycaemic control among people living with diabetes in rural India? A cross-sectional analysis

BackgroundVisual analogue scale (VAS) is one of the simplest to measure medication adherence. It has neither been widely used for Non communicable diseases (NCD) nor validated for in the Indian setting. We examined the validity of self-reported medication adherence measures in relation to HbA1C in a rural population with diabetes mellitus (DM). MethodsParticipants with DM was administered VAS, Diabetes Self-Management Questionnaire (DMSQ) and assessed for missed pills. Descriptive statistics and logistic regression analysis were done. ResultsWe recruited 1347 participants and 84% of them reported being 100% adherent as per VAS and 83.8% stated that they did not miss any pills. However, 58.2% of participants who reported having 100% adherence had poor glycaemic control, as did 58.1% of those who did not miss any pills. None of the diabetic self-care measures was significantly associated with glycaemic control. ConclusionWe found a lack of association between self-reported adherence measures and glycaemic control in participants with DM suggesting that self-reported adherence scales may not be valid in this population.

Establishing the criterion validity of self-report measures of adherence in hemodialysis through associations with clinical biomarkers: A systematic review and meta-analysis.

Accurate measurement of adherence is crucial to rigorously evaluate interventions aimed at improving this outcome in patients undergoing in-center hemodialysis. Previous research has shown great variability in non-adherence rates between studies, mainly due to the use of different direct (e.g., clinical biomarkers) and indirect (e.g., questionnaires) measures. Although self-reported adherence in hemodialysis has been widely explored, it is still unclear which is the most accurate questionnaire to assess this outcome; therefore, the question of how to optimize adherence measurement in research and clinical practice has emerged as a key issue that needs to be addressed. This systematic review and meta-analysis aimed to explore the criterion validity of self-report measures of adherence in hemodialysis established through the association between test scores and clinical biomarkers (the criterion measure). The protocol was registered in PROSPERO (2021 CRD42021267550). The last search was performed on March 29th, 2022, on Web of Science (all databases included), Scopus, CINHAL, APA PsycInfo, and MEDLINE/PubMed. Twenty-nine primary studies were included, and thirty-eight associations were analyzed. The Hunter-Schmidt’s meta-analysis was computed for the associations with more than two studies (n = 20). The results showed that six associations were large (16%), 11 were medium (29%) and the remaining were of small strength. The test scores from the End-Stage Renal Disease Adherence Questionnaire (range: 0.212<rc <0.319) and the Dialysis Diet and Fluid Non-Adherence Questionnaire (range: 0.206<rc <0.359) had medium to large strength associations with interdialytic weight gain, serum phosphorus, and potassium levels, indicating that these questionnaires have reasonable concurrent criterion validity to measure fluid control and adherence to dietary restrictions in patients receiving hemodialysis. The available data did not allow exploring the criterion validity of the test scores in relation to hemodialysis attendance (skipping and/or shortening sessions). These results suggest that the decision to use one questionnaire over another must be made with caution, as researchers need to consider the characteristics of the sample and the objectives of the study. Given that direct and indirect methods have their advantages and disadvantages, the combination of adherence measures in hemodialysis is recommended to accurately assess this complex and multidimensional outcome.

Delay discounting of money and health outcomes, and adherence to policy guidelines during the COVID-19 pandemic.

Delay discounting refers to the observation that the subjective value of an outcome decreases as the delay to its receipt increases. It is well-established that steep delay discounting is related to various maladaptive behaviors, including poorer health-related choices. One of the current challenges of public health policies that emerged during the COVID-19 pandemic is to encourage preventive behaviors against infectious diseases. In this study, we aimed to explore possible underpinnings of adherence to COVID-19 related public health policy guidelines such as disinfection, distancing, and masks (DDM). Participants completed monetary and health discounting tasks across two outcome amounts in gain and loss conditions, and they provided self-report measures of adherence to the DDM policy. Contrary to the theoretically plausible prediction that higher discounting rates would be negatively associated with adherence to health-related public policy guidelines, we found no compelling evidence to support such statement. We discuss the potential weaknesses of declarative measurements of attitudes toward COVID-19 and consider using behavioral interventions for influencing discounting rates for complementing and enhancing current policy guidelines.

Randomized Controlled Trial of Automated Directly Observed Therapy for Measurement and Support of PrEP Adherence Among Young Men Who have Sex with Men

Measurement of adherence to oral pre-exposure prophylaxis (PrEP) in real-time has been challenging. We developed DOT Diary, a smartphone application that combines automated directly observed therapy with a PrEP adherence visualization toolkit, and tested its ability to measure PrEP adherence and to increase adherence among a diverse cohort of young men who have sex with men (MSM). We enrolled 100 MSM in San Francisco and Atlanta and randomly assigned them 2:1 to DOT Diary versus standard of care. Concordance between DOT Diary measurement and drug levels in dried blood spots was substantial, with 91.0% and 85.3% concordance between DOT Diary and emtricitabine-triphosphate and tenofovir-diphosphate, respectively. There was no significant difference in the proportion of participants with detectable PrEP drug levels at 24 weeks between study arms. These results suggest DOT Diary is substantially better than self-reported measures of adherence, but additional interventions are needed to improve PrEP adherence over time.
