Kalichman SC, Eaton LA, Kalichman MO. Perceived sensitivity to medicines and medication concerns beliefs predict intentional nonadherence to antiretroviral therapy among young people living with HIV. Psychol Health 2024; 39:931-946. [PMID: 36111623 DOI: 10.1080/08870446.2022.2122462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 09/01/2022] [Indexed: 10/14/2022]
Abstract
Objective: Among the sources of antiretroviral therapy (ART) nonadherence are patient decisions to skip or stop taking their medications, often stemming from medication beliefs and concerns about side- effects. While individuals who perceive greater sensitivity to medicines may be prone to medication concerns, understanding how these factors contribute to HIV treatment adherence requires further research. The current study tested the direct and indirect effects of perceived sensitivity to medicines on intentional nonadherence to ART, and whether medication concerns mediate this association. Methods: A sample of 418 younger (< 36 years of age) people living with HIV was recruited through community outreach to complete assessments of perceived sensitivity to medicines, medication concerns beliefs, adherence assessed by unannounced phone- based pill counts and HIV viral load, as well as monthly follow- up assessments of intentional nonadherence over a 15- month period. Results: Analyses at baseline and prospective Poisson regression models conducted over 15- months converged to show that perceived sensitivity to medicines significantly predicted intentional nonadherence to ART through medication concerns. Conclusions: These findings suggest that people who perceive greater sensitivity to medicines are prone to greater medication concerns that are related to intentional nonadherence. Cognitive behavioral interventions are needed to resolve medication concerns and reduce intentional nonadherence among people receiving ART.

The three-item patient-reported instrument for retrospective adherence in resource constrained settings: reliability, validity and potential utility. J Behav Med 2024; 47:135-143.

Abstract
INTRODUCTION Patient-report instruments remain the most feasible and sustainable approaches for monitoring medication adherence in clinical settings. However, questions of their reliability and validity persist. Studies suggest that the 3-item instrument for retrospective adherence (IRA) developed by Wilson et al. offers a viable option for clinically monitoring medication adherence. Here we report the reliability and validity of the IRA among patients recruited from community-based HIV clinics and antiretroviral therapy (ART) dispensaries in a resource constrained township in Cape Town, South Africa. METHODS Women (n = 794) and men (n = 228) receiving ART completed the IRA at three time points: (a) in a face-to-face administration at enrollment (b) in1-week phone interview and (c) 1-month phone interview. Participants also provided contemporaneous blood samples for HIV viral load testing as a clinical outcome and unannounced phone-based pill counts as an objective assessment of ART adherence. RESULTS The IRA was internally consistent and showed evidence of time stability. The IRA also demonstrated validity with respect to pill count adherence, correlates of adherence, and HIV viral load. Response operating curve analysis yielded an area under the curve of 0.646, using 75% adherence as the cut-off, with 0.637 sensitivity and 0.567 specificity. CONCLUSIONS The IRA demonstrated reliability, construct validity and criterion validity in a resource constrained setting, supporting use of the IRA in research and clinical care.

Abstract
BACKGROUND Phone-delivered counseling has demonstrated improved health outcomes for people living with HIV. However, counseling is hampered by a lack of guidance on the frequency and duration of intervention in relation to clinical benefits. The added benefits of bidirectional (ie, interactive) vs. unidirectional (ie, passive) text messages to augment counseling are also unknown. We conducted a clinical trial of adaptive phone counseling along with either bidirectional or unidirectional text messaging for people living with HIV. METHODS A community sample of 425 young people (aged 16-36 years) living with HIV in Georgia, USA, received weekly phone counseling sessions with the number of sessions determined by the participant and their counselor. Participants were subsequently randomized to either (1) weekly bidirectional text messages with their counselor or (2) weekly automated unidirectional text message reminders. Participants were followed for 16 months to assess 3 primary outcomes: antiretroviral therapy (ART) adherence, HIV care engagement, and HIV suppression. RESULTS Participants demonstrated improved clinical outcomes over the follow-up period, with 74% of those who were not taking ART initiating treatment, 65% of those on ART improving adherence, and 47% who had detectable viral loads at baseline attaining viral suppression. The number of sessions completed predicted improved ART adherence, greater care engagement, and HIV suppression over follow-ups. Bidirectional text messages impacted care engagement by moderating the effects of counseling sessions on HIV suppression. CONCLUSIONS Phone counseling augmented by bidirectional text messages has the potential to improve HIV care for young adults living with HIV.

JAMA Netw Open 2023; 6:e2336964. [PMID: 37792373 PMCID: PMC10551772 DOI: 10.1001/jamanetworkopen.2023.36964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/28/2023] [Indexed: 10/05/2023] Open
Abstract
Importance Youth-onset type 2 diabetes is associated with early development of chronic complications. Treatment of elevated blood pressure (BP), nephropathy, and dyslipidemia are critical to reduce morbidity. Data are needed on adherence to BP- and lipid-lowering medications in young adults with youth-onset diabetes. Objective To assess adherence and factors associated with adherence to BP- and lipid-lowering medications in young adults with youth-onset type 2 diabetes and diagnoses of hypertension, nephropathy, or dyslipidemia. Design, Setting, and Participants This cohort study measured medication adherence with 3 monthly unannounced pill counts at 2 time points 1 year apart during iCount, conducted during the last years (2017-2019) of the observational phase of the Treatment Options for Type 2 Diabetes in Adolescents and Youth study. Psychosocial factors associated with medication adherence were examined. Participants included individuals with youth-onset type 2 diabetes with hypertension, nephropathy, or dyslipidemia receiving diabetes care in their communities. Data were analyzed from September 2022 to September 2023. Main Outcomes and Measures The main outcome was BP- and lipid-lowering medication adherence, with low adherence defined as using less than 80% of pills and high adherence, at least 80% of pills. Psychosocial factors were measured using the Beliefs about Medicines Questionnaire and Material Needs Insecurities Survey. Results Of 381 participants in iCount, 243 participants (mean [SD] age, 26.12 [2.51] years; 159 [65.43%] women) with hypertension, nephropathy, or dyslipidemia were included in analysis. Among 196 participants with hypertension or nephropathy, 157 (80.1%) had low adherence. Participants with low adherence, compared with those with high adherence, were younger (mean [SD] age, 25.99 [2.41] vs 27.26 [2.41] years; P = .005), had higher glycated hemoglobin A1c (mean [SD], 10.33% [2.66 percentage points] vs 8.85% [2.39 percentage points]; P = .001), shorter diabetes duration (mean [SD], 12.32 [1.49] vs 12.90 [1.46] years; P = .03), and less education (eg, 17 participants [10.83%] vs 0 participants with no high school diploma; P = .004). Of 146 participants with dyslipidemia, 137 (93.8%) had low adherence and only 9 participants (6.2%) had high adherence. Of 103 participants with low adherence to BP-lowering medications and using oral hypoglycemic agents, 83 (80.58%) had low adherence to oral hypoglycemic agents. Beliefs that medications are necessary were higher for participants with high adherence to BP-lowering medications than those with low adherence in unadjusted analyses (mean [SD] necessity score, 16.87 [6.78] vs 13.89 [9.15]; P = .03). In adjusted multivariable analyses of participants with hypertension or nephropathy, having at least 1 unmet social need (odds ratio [OR], 0.20; 95% CI, 0.05-0.65; P = .04) and medication concerns (OR, 0.63; 95% CI, 0.40-0.96; P = .01) were associated with worse medication adherence 1 year follow-up. Diabetes distress, self-efficacy, depressive and anxiety symptoms, and self-management support were not associated with 1-year medication adherence. Conclusions and Relevance These findings suggest that adherence to BP- and lipid-lowering medications was very poor in this cohort. To improve medication adherence and prevent early vascular events, approaches that identify and address medication concerns and unmet social needs are needed.

Abstract
Cross-sectional studies have reported that people living with HIV experienced disruptions to social relationships and healthcare during the first year of the COVID-19 pandemic. Furthermore, individuals with less trust in public health sources of COVID-19 information as well as those who held greater COVID-19 prejudicial attitudes experienced greater healthcare disruptions in the early months of COVID-19. To examine changes in trust and prejudicial attitudes in relation to healthcare disruptions during the first year of COVID-19, we followed a closed cohort of 115 men and 26 women ages 18 to 36 living with HIV over the first year of the COVID-19 pandemic. Findings confirmed that a majority of individuals continued to experience disruptions to their social relationships and healthcare over the course of the first year of COVID-19. In addition, trust in COVID-19 information from the CDC and state health department diminished over the year as did COVID-19 prejudicial attitudes. Regression models showed that lower trust in the CDC and health department and greater prejudicial attitudes toward COVID-19 early in the pandemic predicted greater healthcare disruptions over the year. In addition, greater trust in the CDC and health department early in COVID-19 predicted better antiretroviral therapy adherence later in the year. Results support an urgent need to regain and sustain trust in public health authorities among vulnerable populations.

Abstract
Substance use has complex associations to HIV disease progression. The current study tested the associations between several substances and HIV viral load while accounting for confounders relevant to HIV disease progression and substance use. Young sexual minority men and transgender women living with HIV (LWH) in Georgia (N = 385) completed measures and biological tests for HIV viral load and substance use. Multivariable regression models tested the role of specific drugs (i.e., alcohol, cannabis/THC, cocaine, and combined amphetamine and methamphetamine) directly on viral load and indirectly through antiretroviral (ART) adherence. ART adherence and HIV care self-efficacy were consistently associated with greater HIV suppression. Alcohol and cocaine were not associated with ART adherence or viral load. Cannabis was negatively associated with ART adherence (B = -.053, p = .037) but not viral load. Amphetamine/methamphetamine demonstrated significant direct effects on higher viral load (B = .708, p = .010) while indirectly influencing viral load through a negative association with ART adherence. Our findings support previous research demonstrating amphetamine/methamphetamine use impacts viral load both directly and indirectly through ART adherence. Interventions addressing amphetamine/methamphetamine use by young sexual minority men and transgender women LWH are urgently needed, and future research should focus on determining the mechanisms by which formulations of amphetamine impact HIV replication.Trial registration: ClinicalTrials.gov identifier: NCT03665532.

Abstract
ABSTRACT Studies have reported significant immediate impacts of the COVID-19 pandemic on the social relationships and health care of people living with HIV. This study followed a closed cohort of young people living with HIV over the first year of the COVID-19 pandemic. Participants were men and women (N = 140) age 36 years and younger who were living with HIV and had demonstrated suboptimal adherence to antiretroviral therapy, unsuppressed HIV viral load, or active substance use in a run-in study. The results confirmed that participants continued to experience significant disruptions to their social relationships and health care over the course of the first year of the COVID-19 pandemic. There was evidence for sustained impacts on transportation, housing stability, and food security during the first year of COVID-19. Multivariable models showed that greater pre-COVID-19 social support predicted greater antiretroviral therapy adherence and greater HIV suppression (lower viral load) over the first year of the COVID-19 pandemic. Efforts to plan and prepare people living with HIV for future social crises, including future pandemics, should emphasize building and sustaining social support.

Abstract
AIM To identify psychosocial predictors of medication adherence in young adults with youth-onset type 2 diabetes in the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY2) cohort. METHODS Participants (mean age: 26 years) completed validated psychosocial measures. Unannounced telephone pill counts were completed at T1 (baseline) and T2 (follow-up, approximately 1 year later) to assess adherence to oral hypoglycaemia agents (OHAs). Adherence to insulin was assessed by self-report. Logistic and linear regressions identified factors that predicted 'low adherence' (<80% of pills/insulin) and per cent adherence, adjusted for potential confounders. RESULTS Of 171 participants with OHA adherence scores at T1 and T2 (65% women, 43% Hispanic and 35% non-Hispanic Black), 65.4% were low adherent. After adjustment (including T1 adherence), concerns about diabetes medicines (adverse effects, dependence) at T1 predicted higher odds of being low adherent (categorical) at T2 (p = 0.019). Housing insecurity (p = 0.045) and reporting ≥2 need insecurities (p = 0.027) at T1 predicted lower per cent adherence (continuous) at T2. Of 157 participants with insulin adherence scores at T1 and T2 (69% women, 38% Hispanic and 38% non-Hispanic Black), 36.3% were low adherent. After adjustment (including T1 adherence), beliefs that medicines are overused predicted higher odds of insulin low adherence at T2 (p = 0.013), and beliefs that medicines are harmful (p = 0.004) and overused (p = 0.010) predicted lower per cent insulin adherence at T2. CONCLUSIONS Suboptimal medication adherence, common in young adults with youth-onset type 2 diabetes, is predicted by interfering beliefs about medicines and social factors. We must address these beliefs and unmet needs to develop tailored interventions for this vulnerable group.

Abstract
We aimed to assess the validity of an announced telephone pill count in people with type 2 diabetes or cardiovascular disease by comparing this method to a home-visit pill count. We also assessed whether a second telephone pill count improved accuracy. People aged ≥35 years using oral type 2 diabetes or cardiovascular disease medication were included. Thirty-four participants completed a telephone pill count followed by a home-visit pill count, and a subsample of this population (n = 11) completed a second telephone pill count. Scatterplots were used for a visual representation of the number of pills counted with both methods, intraclass correlation coefficients for agreement, and Bland-Altman plots for absolute differences and outliers. A total of 203 pill counts were conducted. The study population consisted of 53% men, with a mean age of 69.6 (±9.2) years and an average of 6.1 (±2.8) medication prescriptions per participant. Scatterplots showed that pills counted with both methods were mostly scattered around the y = x equation. Agreement between the first telephone pill count and home-visit pill count was high, with intraclass correlation coefficients of 0.96 (medication count level) and 0.98 (individual level). No learning effects were observed in the subsample (n = 11), the intraclass correlation coefficient for the first telephone pill count was 0.88 versus 0.89 for the second telephone pill count. Bland-Altman plots indicated high agreement between the two methods. An announced telephone pill count is considered a valid alternative for a home-visit pill count in people with type 2 diabetes or cardiovascular disease. A single pill count appears sufficient.

A personalised intervention programme aimed at improving adherence to oral antidiabetic and/or antihypertensive medication in people with type 2 diabetes mellitus, the INTENSE study: study protocol for a randomised controlled trial. Trials 2022; 23:731. [PMID: 36056388 PMCID: PMC9438235 DOI: 10.1186/s13063-022-06491-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 06/21/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Medication non-adherence is a prevalent health problem in people with type 2 diabetes mellitus (T2DM). Interventions have previously been developed to improve medication adherence, but inconsistent outcomes have been reported. A potential explanation for this inconsistency is a 'one size fits all' approach, with interventions not tailored to the needs and preferences of individuals. Therefore, the aim of this study is to evaluate the effectiveness of a personalised intervention programme aimed at improving adherence to oral antidiabetic and/or antihypertensive medication in people with T2DM. METHODS A parallel-group randomised controlled trial will be conducted in 40-50 community pharmacies in the Netherlands and the United Kingdom (UK). A total of 300 participants will be included and followed up for a period of 6 months. Participants will be people with T2DM identified as non-adherent to oral antidiabetic and/or antihypertensive medication, aged 35-75 years and mobile phone users. The intervention group will receive a personalised intervention programme that is based on one or more of the participants' pre-defined non-adherence profile(s), namely (I) Knowledge and perceptions, (II) Practical problems, (III) Side effects and (IV) Negative mood and beliefs. The intervention comprises of one or more supporting modules, namely (I) Brief messaging, (II) Clinical medication review, (III) Medication schedule, (IV) Reminding messaging, (V) Medication dispensing systems, (VI) Smart messaging, (VII) Referral to general practitioner and (VIII) Unguided web-based Self Help Application for low mood. The control group will receive usual care including access to a publicly available informative diabetes website. The primary study outcome is medication adherence measured with a telephone pill count. Secondary outcomes are systolic blood pressure, HbA1c level, self-reported medication adherence, attitude and beliefs toward medication, satisfaction with diabetes treatment, health status and medical consumption and productivity cost. In addition, a process evaluation will be undertaken to establish the fidelity, reach and the extent to which intervention delivery is normalised in the daily practice of community pharmacy teams. DISCUSSION The study can lead to a personalised intervention programme that improves medication adherence in people with T2DM that are non-adherent to oral antidiabetic and/or antihypertensive medication.

Abstract
This study tested the hypothesis that the co-occurrence of alcohol use and depressive symptoms predicts HIV suppression and antiretroviral therapy (ART) adherence among people living with HIV. Baseline cross-sectional results showed a significant interaction between depressive symptoms and alcohol use in predicting HIV suppression; individuals who drank more alcohol and had higher depressive symptoms demonstrated poorer HIV suppression relative to those who had fewer depressive symptoms. In a one-year longitudinal analysis of ART adherence, alcohol use and depressive symptoms measured in daily text-message assessments demonstrated that neither alcohol use nor depressive symptoms alone predicted ART adherence. However, the intersection of alcohol use on days when experiencing depressive symptoms did significantly predict ART non-adherence, for both moderate and heavy alcohol drinkers. Findings suggest that the co-occurrence of alcohol use and depressive symptoms is a robust predictor of poor HIV treatment outcomes.

Abstract
BACKGROUND Drinking alcohol is a robust predictor of medication nonadherence. In addition to the impact of intoxication on adherence, individuals who believe that it is hazardous to mix medications with alcohol (ie, interactive toxicity beliefs) may forgo taking their medications when drinking. Previous research suggests that alcohol-related intentional nonadherence is a direct result of interactive toxicity beliefs. This study prospectively tested the association between alcohol interactive toxicity beliefs and intentional nonadherence to HIV treatment [ie, antiretroviral therapy (ART)]. METHODS Four hundred eight people living with HIV completed comprehensive baseline assessments and 15-month attributions for ART nonadherence. RESULTS One in 5 participants reported foregoing taking their ART when drinking out of concern for hazardous mixing of alcohol and ART. Poisson regression models predicting the number of months that participants were intentionally nonadherent to ART because they were drinking was predicted by alcohol-ART interactive toxicity beliefs. CONCLUSIONS Beliefs that it is hazardous to drink alcohol when taking medications explains intentional nonadherence and should be directly addressed in adherence improvement interventions for people living with HIV who drink alcohol.

Abstract
AIMS To assess prevalence of, and factors associated with, medication adherence of young adults with youth-onset type 2 diabetes. METHODS Oral hypoglycaemia agent (OHA) adherence was measured with unannounced telephone pill counts, insulin adherence was self-reported. Those taking ≥ 80% of pills/insulin were classified "high-adherent," <80% of pills/insulin "low-adherent." Analyses included unadjusted, and adjusted linear and logistic regressions assessing associations of participant factors with adherence. RESULTS For people taking OHAs (N = 212, mean age 26 yrs, 67% women, 18% non-Hispanic White, 35% non-Hispanic Black, 41% Hispanic), 69.8% were low-adherent. HbA1c was lower in the high-adherent group (9.2%/77 mmol/mol vs. 10.0%/86 mmol/mol, p < 0.04). More non-Hispanic Blacks were low-adherent (85.7%) than Hispanics (60.2%) and non-Hispanic whites (55.3%, p < 0.002); 91.4% of participants without healthcare coverage were low-adherent vs. 65.5% of those with coverage (p < 0.004). After adjustment, gender (p = 0.024), race/ethnicity (p < 0.001) and healthcare coverage (p = 0.001) remained related to OHA adherence. For insulin (N = 192), 37% were low-adherent. HbA1c was associated with insulin adherence (low = 11.2%/99 mmol/mol vs. high = 10.0%/86 mmol/mol, p < 0.001) with and without adjustment. CONCLUSIONS Young adults with youth-onset type 2 diabetes, especially females, non-Hispanic Blacks and those without healthcare coverage, commonly had low-OHA adherence. Glycaemic control was also poor. Interventions to improve medication adherence are needed for this vulnerable group.

Abstract
BACKGROUND To date, no studies have reported the use of text messaging to deliver cognitive behavioral therapy (CBT) to people living with HIV and substance use disorders. OBJECTIVE We developed and evaluated a 12-week, CBT-based text-messaging intervention (TXT-CBT) targeting drug use and adherence to antiretroviral therapy (ART) for adults with HIV and comorbid opioid and stimulant use disorders. MATERIALS AND METHODS Participants were randomly assigned to receive either TXT-CBT (n = 25) or an informational pamphlet (INFO) discussing substance use and medication adherence (n = 25). ART adherence, drug use, and HIV-risk behaviors were assessed at baseline, monthly during treatment, and treatment-end, and were compared between groups using a mixed-model repeated-measures analysis. Injection drug use was examined as a moderator of outcomes. RESULTS Relative to the INFO group, TXT-CBT participants evidenced increased ART adherence, measured by phone-based unannounced pill counts and biochemically by viral load and CD4 count. TXT-CBT participation was also associated with reductions in opioid use and HIV risk behaviors. While reductions in cocaine use were observed in the TXT-CBT group, relative to the INFO group, other stimulant use did not change. Among people who inject drugs, TXT-CBT produced increases in ART adherence and corresponding changes in viral load, relative to injection drug users in the control condition. CONCLUSIONS Findings demonstrated promising preliminary evidence for the efficacy of TXT-CBT in improving ART adherence and reducing drug use and HIV-risk behaviors among people with HIV infection and comorbid opioid and stimulant use disorders.

Abstract
Antiretroviral therapy (ART) reduces HIV disease burden, increases life expectancy, and prevents HIV transmission. Previous research suggests that believing that it is harmful to take ART when using substances (i.e., interactive toxicity beliefs) leads to intentional ART nonadherence; however, these associations have not been investigated among younger adults living with HIV and have not been linked to clinical outcomes. We examined the associations among interactive toxicity beliefs, intentional nonadherence, and HIV clinical outcomes in young adults living with HIV. People living with HIV younger than the age of 36 years who tested positive for at least one substance use biomarker (N = 406) completed a 1-month pretrial run-in study that included computerized interviews, substance use biomarkers, HIV viral load, and unannounced pill counts for ART adherence. Analyses compared three HIV clinical outcome groups: (1) HIV viral unsuppressed, (2) HIV viral suppressed and ART nonadherent, and (3) HIV viral suppressed and ART adherent, on substance use, interactive toxicity beliefs, and substance use-related intentional ART nonadherence. Results showed that a majority of participants reported intentional nonadherence. Participants with unsuppressed HIV reported greater interactive toxicity beliefs and intentional nonadherence. We conclude that intentional nonadherence adds to the detrimental impacts of substance use on ART adherence and interactive toxicity beliefs that foster these behaviors may be amenable to interventions.

Abstract
Undetected sexually transmitted infections (STIs) pose health threats to people living with HIV and when combined with uncontrolled HIV can amplify HIV transmission. The current study screened 174 self-identified men under age 36 living with HIV and receiving antiretroviral therapy (ART) for urethral and rectal incident chlamydia and gonorrhea infections. Participants were also screened for biomarkers indicating alcohol and other drug use, subclinical genital inflammation, and HIV viral load. ART adherence and sexual behaviors were also assessed prospectively over 1 month. Results detected an undiagnosed STI in 32 (18%) individuals. Participants with a previously undetected STI had significantly greater HIV viremia than those who did not have an STI after controlling for several confounding variables. Participants with an undetected STI also engaged in greater condomless anal intercourse with HIV negative and unknown status partners, including partners to whom they had not disclosed their HIV status. These findings show that undetected STI are associated with incomplete ART adherence and unsuppressed HIV, all of which are important for preventing HIV transmission.

Abstract
BACKGROUND Adherence to antiretroviral therapy (ART) and sustained HIV suppression virtually eliminate HIV transmission, eg, having an undetectable viral load renders HIV untransmittable (U=U). Owing to the greatly reduced likelihood of HIV transmission when viral load is undetectable, we studied one behavioral ramification of adopting a U=U prevention strategy-not disclosing HIV status to sex partners. SETTING Cisgender men recruited through community outreach in the state of Georgia, USA. METHODS We examined HIV status disclosure to sex partners among 345 young (median age = 29 years) men receiving ART. Data were collected using computerized interviews, daily sexual behavior surveys over 28 days, unannounced pill counts for ART adherence, urine tests for drug use and urogenital health, and blood samples for HIV viral load. RESULTS One in 3 participants (34%) engaged in condomless anal/vaginal intercourse with an HIV-negative/unknown HIV status partner over 28 days. Average ART adherence was 76%, and one in 5 men had detectable HIV viral loads. Men who engaged in condomless sex with undisclosed partners demonstrated significantly less HIV disclosure to family and friends and had fewer enacted stigma experiences. Hierarchical regression models showed that endorsing U=U as a personal HIV prevention strategy predicted undisclosed condomless sex over and above substance use, HIV stigma experiences, disclosure to family and friends, ART adherence, and HIV viral load. CONCLUSIONS Interventions are needed to improve ART adherence and assist men living with HIV in their decisions to disclose HIV status to sex partners.

Abstract
PURPOSE To test the efficacy of a theory-based behavioral intervention delivered via telephone versus clinic-based counseling to improve HIV outcomes and reduce alcohol consumption for people at-risk for treatment failure in a rural setting. METHODS Patients receiving HIV care (N = 240) were randomized using a computer-generated scheme to one of three conditions: (a) telephone behavioral health counseling, (b) clinic-based behavioral health counseling, or (c) attention control nutrition education. Behavioral counseling was delivered by either a community nurse or a paraprofessional patient navigator, with differences examined. Participants were followed for 12 months to assess medication adherence using unannounced pill counts and alcohol use measured by electronic daily text message assessments, and 18 months for HIV viral load and retention in care extracted from medical records. FINDINGS There was evidence for telephone and office-based counseling demonstrating greater medication adherence than the control condition but only in the short term. Clinic-based behavioral counseling significantly reduced alcohol use to a greater degree than telephone counseling and the control condition. There were no other differences between conditions. There were also no discernable differences between counseling delivered by the community nurse and the patient navigator. CONCLUSIONS Telephone and clinic-based counseling demonstrated improved medication adherence in the short term, while clinic-based counseling demonstrated reductions in alcohol use. The modest outcomes suggest that intensive intervention strategies are needed for patients that clinicians identify as at-risk for treatment discontinuation and treatment failure.

Abstract
With the expansion of telehealth services, there is a need for evidence-based treatment adherence interventions that can be delivered remotely to people living with HIV. Evidence-based behavioral health counseling can be delivered via telephone, as well as in-office services. However, there is limited research on counseling delivery formats and their differential outcomes. The purpose of this study was to conduct a head-to-head comparison of behavioral self-regulation counseling delivered by telephone versus behavioral self-regulation counseling delivered by in-office sessions to improve HIV treatment outcomes. Patients (N = 251) deemed at risk for discontinuing care and treatment failure living in a rural area of the southeastern USA were referred by their care provider. The trial implemented a Wennberg Randomized Preferential Design to rigorously test: (a) patient preference and (b) comparative effects on patient retention in care and treatment adherence. There was a clear patient preference for telephone-delivered counseling (69%) over in-office-delivered counseling (31%) and participants who received telephone counseling completed a greater number of sessions. There were few differences between the two intervention delivery formats on clinical appointment attendance, antiretroviral adherence, and HIV viral load. Overall improvements in health outcomes were not observed across delivery formats. Telephone-delivered counseling did show somewhat greater benefit for improving depression symptoms, whereas in-office services demonstrated greater benefits for reducing alcohol use. These results encourage offering most patients the choice of telephone and in-office behavioral health counseling and suggest that more intensive interventions may be needed to improve clinical outcomes for people living with HIV who may be at risk for discontinuing care or experiencing HIV treatment failure.

Abstract
BACKGROUND Youth living with HIV (YLHIV) in Sub-Saharan African (SSA) are less likely to adhere to antiretroviral therapy (ART) and other health-related regimens. As a consequence, YLHIV are not only at risk for health problems and mental health comorbidities, but are also at risk for cognitive deficits, including in areas of memory and executive functioning. The Suubi+Adherence study followed 702 adolescents (10-16 years of age) receiving bolstered standard of care and a family economic empowerment intervention comprising an incentivized youth financial savings account (YSA) augmented with financial literacy training (FLT) and peer mentorship. The study findings pointed to superior short-term viral suppression and positive adolescent health and mental health functioning among participants receiving the intervention. The original group of adolescents who received Suubi+Adherence are now transitioning into young adulthood. This paper presents a protocol for the follow-up phase titled Suubi+Adherence Round 2. METHODS The original cohort in Suubi+Adherence will be tracked for an additional five years (2020-2025). Specifically, the long term follow-up will allow to: 1) ascertain the extent to which the short term outcomes identified in the first 6 years of the intervention are maintained as the same group transitions through young adulthood; and 2) address new scientific questions regarding ART adherence; HIV care engagement; protective health behaviors; and the potential of FEE to mitigate the development of HIV-associated neurocognitive disorders in YLHIV. Additionally, the team examines the potential mechanisms through which the observed long-term outcomes happen. Moreover, the Suubi+Adherence-Round 2 adds a qualitative component and extends the cost effectiveness component. DISCUSSION Guided by asset and human development theories, Suubi+Adherence-R2 will build on the recently concluded Suubi+Adherence study to conduct one of the largest and longest running studies of YLHIV in SSA as they transition into young adulthood. The study will address new scientific questions regarding long-term ART adherence, HIV care engagement, protective health behaviors, and the potential of FEE to mitigate the development of HIV-associated neurocognitive disorders in YLHIV. The findings may inform efforts to improve HIV care among Uganda's YLHIV, with potential replicability in other low-resource countries. TRIAL REGISTRATION ClinicalTrials.gov , ID: NCT01790373.

Abstract
Lower health literacy is associated with poorer health outcomes in people living with HIV (PLWH), but the explanatory mechanisms for these associations are not well understood. Factors such as drug use and life chaos may at least in part account for the relationship between lower health literacy and poor health outcomes. The current study tested the hypothesis that lower health literacy would predict drug use, which in turn would predict life chaos, and that all three factors would be related to poorer heath, defined by higher concentrations of HIV viremia. Methods: Patients receiving HIV care (N = 251) at an HIV clinic in the southeastern United States completed computerized interviews and permission to access their medical records. Process modeling tested direct and indirect effects of all variables in a serial mediation model. Results: The direct effects of lower health literacy and drug use were significantly related to HIV viremia. In addition, the indirect effect of health literacy on HIV viremia through drug use was significant. However, results did not demonstrate any effect, direct or indirect, of life chaos on HIV viremia. Conclusion: Findings from this study bolster previous research demonstrating lower health literacy and drug use as barriers to HIV care, and show that lower health literacy impacts HIV viremia, at least in part, through drug use. Interventions aimed to improve HIV treatment outcomes in lower health literacy populations may be enhanced by integrating evidence-based approaches to reducing drug use.

Abstract
This study explored whether telephone-delivered mindfulness training (MT) to promote medication adherence and reduce sexual risk behavior was feasible for and acceptable to people living with HIV. Participants (N = 42; 50% female; M age = 47.5 years) were randomized to MT or health coaching (HC). Pre- and post-intervention, and at 3-month follow-up, we assessed adherence to ART, sexual risk behavior, and hypothesized mediators; we also conducted individual interviews to obtain qualitative data. Results showed that 55% of patients assigned to MT completed ≥ 50% of the training calls compared with 86% of HC patients (p < .05). Most patients reported satisfaction with their intervention (MT = 88%, HC = 87%). Patients in MT and HC reported improvements in medication adherence, mindfulness, and sexual risk reduction as well as reductions in anxiety, depressive symptoms, perceived stress, and impulsivity over time; however, no between-groups differences were observed.

Antiretroviral Adherence Following Prison Release in a Randomized Trial of the imPACT Intervention to Maintain Suppression of HIV Viremia. AIDS Behav 2019; 23:2386-2395.

Abstract
Many people living with HIV (PLWH) pass through correctional facilities each year, a large proportion of whom do not maintain viral suppression following release. We examined the effects of imPACT, an intervention designed to promote post-release viral suppression, on antiretroviral therapy (ART) adherence. PLWH awaiting release from prisons in two southern states were randomized to imPACT (consisting of motivational interviewing, care linkage coordination, and text message medication reminders) versus standard care (SC). ART adherence, measured by unannounced monthly telephone pill counts, was compared between study arms over 6 months post-release. Of 381 participants eligible for post-release follow-up, 302 (79%) completed ≥ 1 of 6 possible pill counts (median: 4; IQR 1-6). Average adherence over follow-up was 80.3% (95% CI 77.5, 83.1) and 81.0% (78.3, 83.6) of expected doses taken in the imPACT and SC arms, respectively. There was no difference between arms when accounting for missing data using multiple imputation (mean difference = - 0.2 percentage points [- 3.7, 3.3]), controlling for study site and week of follow-up. Of the 936 (40.9%) pill counts that were missed, 212 (22.7%) were due to re-incarceration. Those who missed pill counts for any reason were more likely to be unsuppressed, suggesting that they had lower adherence. However, missingness was balanced between arms. Among PLWH released from prison, ART adherence averaged > 80% in both study arms over 6 months-a level higher than seen with most other chronic diseases. However, missing data may have led to an overestimate of adherence. Factors independent of the intervention influence ART adherence in this population and should be identified to inform future targeted interventions.

Abstract
We report the reliability, validity, and feasibility of self-performed picture pill count (PPC) as an adherence measure that was used in a randomized trial with HIV positive people living in rural Georgia. The first 61 (of 149) participants conducted an additional PPC 1-2 days after baseline. Reliability, measured by a PPC scoring instrument, analyzed participants' ability to reproduce high quality pill count photographs free from artifact or blurring that could hamper accurate visualization of the pills and bottle labels. Except for label blur, baseline photographs (performed with coaching by study staff) and independently performed post-baseline photographs were rated as acceptable quality (> 93%). Label blur significantly worsened between the baseline and post-baseline scoring (93% vs 80%, p = 0.039), possibly indicating that participants required more education to ensure readability. Validity was determined by comparing the number of pills entered into the PC survey with the number of pills in the texted PPC; 77.5% of participants had perfectly matched pill counts (r = 0.690, p < 0.001). We found PCC to be a reliable and valid method of measuring adherence. The high rate of participant satisfaction underscores its feasibility. It provides an innovative alternative to other more invasive and labor intensive methods of measuring adherence using pill counts.

Abstract
Depression is a known risk factor for antiretroviral therapy (ART) non-adherence, but little is known about the mechanisms explaining this relationship. Identifying these mechanisms among people living with HIV (PLHIV) after release from prison is particularly important, as individuals during this critical period are at high risk for both depression and poor ART adherence. 347 PLHIV recently released from prison in North Carolina and Texas were included in analyses to assess mediation of the relationship between depressive symptoms at 2 weeks post-release and ART adherence (assessed by unannounced telephone pill counts) at weeks 9-21 post-release by the hypothesized explanatory mechanisms of alcohol use, drug use, adherence self-efficacy, and adherence motivation (measured at weeks 6 and 14 post-release). Indirect effects were estimated using structural equation models with maximum likelihood estimation and bootstrapped confidence intervals. On average, participants achieved 79% ART adherence. The indirect effect of depression on adherence through drug use was statistically significant; greater symptoms of depression were associated with greater drug use, which was in turn associated with lower adherence. Lower adherence self-efficacy was associated with depressive symptoms, but not with adherence. Depression screening and targeted mental health and substance use services for depressed individuals at risk of substance use constitute important steps to promote adherence to ART after prison release.

Abstract
Background Transgender women living with HIV infection experience poorer health outcomes across the HIV continuum of care. While disparities are well established, their underlying mechanisms are not well understood. This study examined the HIV continuum of care (also known as the HIV treatment cascade), including linkage and engagement in care and health status among transgender women and cisgender women and cisgender men living with HIV. METHOD Case-control matching was applied to a cohort of 1101 people living with HIV; 70 transgender women living with HIV were matched on years since testing HIV positive with cisgender women and cisgender men. Participants provided measures indicative of the HIV treatment cascade that included linkage and engagement in care, receiving and adhering to antiretroviral therapy (ART), and HIV viral suppression. Common correlates of HIV-related health status: depression symptoms, HIV-related stress, alcohol and drug use, healthcare conspiracy beliefs, medical mistrust, emotional social support and tangible social support, were also assessed. RESULTS Transgender women were significantly less likely to receive ART, were less adherent to ART and had poorer HIV viral suppression than cisgender persons. Multivariable models demonstrated that health disparities were predicted by transgender women having poorer tangible social support over and above the other correlates of health outcomes. CONCLUSION Tangible support is amenable by interventions such as building and strengthening supportive networks and paraprofessional services. Socially supportive interventions should be considered critical in efforts to decrease HIV health disparities among transgender women.

Abstract
BACKGROUND Medication adherence after myocardial infarction remains low. Pharmacy claims have typically been used to measure medication adherence, but electronic pill bottles may offer additional information. OBJECTIVE The main objectives of this study were to compare the association of adherence measured by prescription claims and remote monitoring technologies with cardiovascular events. RESEARCH DESIGN This study was a secondary analysis of a remote monitoring intervention to increase medication adherence in myocardial infarction patients. SUBJECTS In total, 682 myocardial infarction patients were randomized to the intervention group with both medical and pharmacy benefits. MEASURES Pharmacy claims adherence was measured using proportion of days covered (PDC) and GlowCap adherence (GC) was measured as the proportion of days the pill bottle was opened. We compared the association of PDC and GC adherence for statins with time to first vascular readmission or death and assessed model fit using Akaike information criterion and Bayesian information criterion and the likelihood ratio test. RESULTS Higher PDC was significantly associated with a lower hazard rate for vascular readmissions or death (hazard ratio=0.435; P=0.009). There was also an association between GC adherence and vascular readmissions or death (hazard ratio=0.313; P≤0.001). Adding the GC adherence variable to the model using only PDC improved the model fit (likelihood ratio test, P=0.001), as well as vice versa (P=0.050). CONCLUSIONS Pharmacy claims data provide useful but not complete data for medication adherence monitoring. New wireless technologies have the potential to provide additional data about clinical outcomes.

Abstract
Due to marked reductions in morbidity and mortality, antiretroviral (ARV) adherence monitoring is of high interest. Researchers and clinicians often resort to the most feasible and cost-effective adherence methods possible, which may result in biased or inaccurate estimates and require the physical presence of a participant at a research or clinic site. The objective of our study was to evaluate the feasibility and acceptability of three objective, innovative, and remote methods to estimate ARV adherence which may be conducted with less time and financial resources in a wide range of clinic and research settings. These three methods included: (a) text-messaged photographs of pharmacy refill dates to measure refill-based adherence, (b) text-messaged photographs of ARV medications to estimate pill-count-based adherence, and (c) home-collected hair samples for the measurement of ARV concentration to determine pharmacologic-based adherence. We conducted a pilot study from March through October 2017 to examine the feasibility and acceptability of these three adherence measures and the remotely conducted study procedures in 93 adults living with HIV nationwide. From our diverse national sample of participants, 95.7% were retained until the end of the study, 89.9% sent all text messages, and 84.3% sent all hair samples. Approximately 74.2% of participants reported excellent overall experience with the study, 60.2% were very or extremely satisfied with participating in a hair collection study, and 76.3% noted extremely high likelihood of participating in a similar study including text messaging pictures of medications or refill dates. We noted high levels of feasibility and acceptability with the remote study methodology, collection of photographed and text messaged pharmacy refill dates and pill counts, and home-collected hair samples. Here we describe the feasibility and acceptability metrics, results from the exit qualitative interviews with the participants, and lessons learned. These adherence measures represent innovative approaches to expand monitoring tools for HIV treatment and prevention adherence in future research.

Abstract
OBJECTIVES We conducted a randomized clinical trial to test a mobile health behavioral intervention designed to enhance HIV treatment as prevention (B-TasP) by simultaneously increasing combination antiretroviral therapies (cART) adherence and improving the sexual health of people living with HIV. METHODS A cohort of sexually active men (n = 383) and women (n = 117) living with HIV were enrolled. Participants were baseline assessed and randomized to either (1) B-TasP adherence and sexual health intervention or (2) general health control intervention. Outcome measures included HIV RNA viral load, cART adherence monitored by unannounced pill counts, indicators of genital tract inflammation, and sexual behaviors assessed over 12 months. RESULTS Eighty-six percent of the cohort was retained for 12-month follow-up. The B-TasP intervention demonstrated significantly lower HIV RNA, OR = 0.56, P = 0.01, greater cART adherence, Wald χ = 33.9, P = 0.01, and fewer indicators of genital tract inflammation, Wald χ = 9.36, P = 0.05, over the follow-up period. Changes in sexual behavior varied, with the B-TasP intervention showing lower rates of substance use in sexual contexts, but higher rates of condomless sex with non-HIV positive partners occurred in the context of significantly greater beliefs that cART reduces HIV transmission. CONCLUSIONS Theory-based mobile health behavioral interventions can simultaneously improve cART adherence and sexual health in people living with HIV. Programs aimed to eliminate HIV transmission by reducing HIV infectiousness should be bundled with behavioral interventions to maximize their impact and increase their chances of success.

Abstract
HIV treatment depends on high-levels of antiretroviral therapy (ART) adherence, which is severely impeded by poverty. Men and women living with HIV infection (N = 92) completed computerized interviews of demographic and health characteristics, poverty markers, stressful life events, and life chaos, as well as unannounced pill counts to determine prospective medication adherence and medical record chart abstractions for HIV viral load. Poverty markers were associated with both stressors and chaos, and the direct effects of all three factors predicted ART non-adherence. The multiple mediation model showed that accounting for stressors and chaos resulted in a non-significant association between poverty markers and ART adherence. The indirect effect of poverty markers on adherence through life chaos was significant, whereas the indirect effect of poverty markers on adherence through stressors was not significant. Factors that render HIV-related stress and create chaos offer intervention targets that are more amenable to change than poverty itself.

Abstract
BACKGROUND Barriers to HIV medication adherence may differ by levels of dosing schedules. PURPOSE The current study examined adherence barriers associated with medication regimen complexity and simplification. METHODS A total of 755 people living with HIV currently taking anti-retroviral therapy were recruited from community services in Atlanta, Georgia. Participants completed audio-computer-assisted self-interviews that assessed demographic and behavioral characteristics, provided their HIV viral load obtained from their health care provider, and completed unannounced phone-based pill counts to monitor medication adherence over 1 month. RESULTS Participants taking a single-tablet regimen (STR) were more likely to be adherent than those taking multi-tablets in a single-dose regimen (single-dose MTR) and those taking multi-tablets in a multi-dose regimen (multi-dose MTR), with no difference between the latter two. Regarding barriers to adherence, individuals taking STR were least likely to report scheduling issues and confusion as reasons for missing doses, but they were equally likely to report multiple lifestyle and logistical barriers to adherence. CONCLUSIONS Adherence interventions may need tailoring to address barriers that are specific to dosing regimens.

Abstract
BACKGROUND There is currently no gold standard for assessing antiretroviral (ARV) adherence, so researchers often resort to the most feasible and cost-effective methods possible (eg, self-report), which may be biased or inaccurate. The goal of our study was to evaluate the feasibility and acceptability of innovative and remote methods to estimate ARV adherence, which can potentially be conducted with less time and financial resources in a wide range of clinic and research settings. Here, we describe the research protocol for studying these novel methods and some lessons learned. METHODS The 6-month pilot study aimed to examine the feasibility and acceptability of a remotely conducted study to evaluate the correlation between: 1) text-messaged photographs of pharmacy refill dates for refill-based adherence; 2) text-messaged photographs of pills for pill count-based adherence; and 3) home-collected hair sample measures of ARV concentration for pharmacologic-based adherence. Participants were sent monthly automated text messages to collect refill dates and pill counts that were taken and sent via mobile telephone photographs, and hair collection kits every 2 months by mail. At the study end, feasibility was calculated by specific metrics, such as the receipt of hair samples and responses to text messages. Participants completed a quantitative survey and qualitative exit interviews to examine the acceptability of these adherence evaluation methods. The relationship between the 3 novel metrics of adherence and self-reported adherence will be assessed. DISCUSSION Investigators conducting adherence research are often limited to using either self-reported adherence, which is subjective, biased, and often overestimated, or other more complex methods. Here, we describe the protocol for evaluating the feasibility and acceptability of 3 novel and remote methods of estimating adherence, with the aim of evaluating the relationships between them. Additionally, we note the lessons learned from the protocol implementation to date. We expect that these novel measures will be feasible and acceptable. The implications of this research will be the identification and evaluation of innovative and accurate metrics of ARV adherence for future implementation.

Abstract
INTRODUCTION Accurate measurement of adherence is necessary to ensure that therapeutic outcomes can be attributed to the recommended treatment. Phone-based unannounced pill counts were shown to be feasible and reliable measures of adherence in developed settings; and have been further used as part of medication adherence interventions. However, it is not clear whether this method can be implemented successfully in resource-limited settings, where cellular network and mobile phone coverage may be low. Our objective is to describe operational issues surrounding the use of phone-based unannounced pill counts in Lesotho and Ethiopia. METHODS Phone-based monthly unannounced pill counts, using an adaptation of a standardized protocol from previous US-based studies, were utilized to measure anti-TB and antiretroviral medication adherence in two implementation science studies in resource-limited settings, START (Lesotho) and ENRICH (Ethiopia). RESULTS In START, 19.6% of calls were completed, with 71.9% of participants reached at least once; majority of failed call attempts were due to phones not being available (54.8%) or because participants were away from the pills (32.7%). In ENRICH, 33.5% of calls were completed, with 86.7% of participants reached at least once; the main reasons for failed call attempts were phones being switched off (31.5%), participants not answering (27.3%), participants' discomfort speaking on the phone (15.4%), and network problems (13.2%). Structural, facility-level, participant-level, and data collection challenges were encountered in these settings. DISCUSSION Phone-based unannounced pill counts were found to be challenging, and response rates suboptimal. While some of these challenges were specific to local contexts, most of them are generalizable to resource-limited settings. In a research study context, a possible solution to ease operational challenges may be to focus phone-based unannounced pill count efforts on a randomly selected sample from participants who are provided with study phones and rigorously ensure that call attempts are made for these participants.

Abstract
Disclosure of HIV-positive status to sex partners is critical to protecting uninfected partners. In addition, people living with HIV often risk criminal prosecution when they do not inform sex partners of their HIV status. The current study examined factors associated with nondisclosure of HIV status by men living with HIV in Atlanta, GA (92% African African, mean age = 43.8), who engage in condomless sex with uninfected sex partners. Sexually active HIV-positive men (N = 538) completed daily electronic sexual behavior assessments over the course of 28 days and completed computerized interviews, drug testing, medication adherence assessments, and HIV viral load retrieved from medical records. Results showed that 166 (30%) men had engaged in condomless vaginal or anal intercourse with an HIV-uninfected or unknown HIV status sex partner to whom they had not disclosed their HIV status. Men who engaged in nondisclosed condomless sex were less adherent to their HIV treatment, more likely to have unsuppressed HIV, demonstrated poorer disclosure self-efficacy, enacted fewer risk reduction communication skills, and held more beliefs that people with HIV are less infectious when treated with antiretroviral therapy. We conclude that undisclosed HIV status is common and related to condomless sex with uninfected partners. Men who engage in nondisclosed condomless sex may also be more infectious given their nonadherence and viral load. Interventions are needed in HIV treatment as prevention contexts that attend to disclosure laws and enhance disclosure self-efficacy, improve risk reduction communication skills, and increase understanding of HIV infectiousness.

Abstract
BACKGROUND HIV infection is clinically managed with antiretroviral therapy (ART), but only with sustained adherence. Cost-efficient interventions to improve and sustain ART adherence remain a pressing priority for populations challenged by nonadherence. The aim of this study was to test the independent and interactive effects of (1) brief phone-delivered self-regulation counseling and (2) daily phone-delivered text message medication reminders on HIV adherence and HIV viral suppression. METHOD A randomized 2 (5 sessions of phone-delivered adherence support counseling vs. contact-matched control) × 2 (daily ART text reminders vs. no reminders) trial with primary end points of monthly phone-based unannounced pill count-determined ART adherence and HIV viral suppression monitored over 12 months. RESULTS Self-regulation adherence counseling demonstrated significant improvements in achieving 90% ART adherence relative to the control group over the first 6 months of follow-up. Effects remained significant in sensitivity analyses conducted at 85% and 95% adherence. Counseling also demonstrated modest but significant effects on HIV suppression. There were no main effects or interactions for daily text message reminders, with some evidence for adverse effects on adherence self-efficacy. CONCLUSIONS Brief adherence support counseling delivered by phone demonstrates clinically meaningful improvements in ART adherence and HIV suppression, although these benefits were not evidenced in all patients or in the long-term. Advancing adherence interventions along with an effective means for sustaining gains in adherence remain priorities if ART is to achieve its potential clinical and public health benefits.

Abstract
BACKGROUND Improving access to paediatric HIV treatment requires both large-scale treatment programmes and medication that is adapted to infants and children's needs. The WHO recommends lopinavir/ritonavir as first-line antiretroviral therapy for all HIV-infected children younger than 3 years. There is currently little evidence on the acceptability of, and adherence to, a formulation of this combination treatment if given in the form of pellets. This protocol presents how we will carry a realist evaluation to assess the factors that contribute to the acceptability and adherence to the new pellets formulation in 3 hospitals in Kenya. METHODS We structured the protocol along the realist evaluation cycle following 4 steps: (1) the initial programme theory, (2) the study design, (3) the data collection methods and (4) the data analysis plan. Theories of behavioural sciences were reviewed for frames that could provide insights into how using such new formulations may contribute to better acceptability and adherence. ETHICS AND DISSEMINATION This study was approved by the Institutional Review Board of the Institute of Tropical Medicine, the Ethical Committee of the University Hospital Antwerp and the Kenyatta National Hospital/University of Nairobi Ethics and Research Committee. We aim to disseminate the findings through international conferences and peer-reviewed journals and to share them with Drugs for Neglected Diseases initiative's (DNDi) programme managers and with the Kenyan healthcare providers. DISCUSSION In developing this study, we encountered some challenges. First, methods to measure the acceptability of any formulation and adherence to it are not standardised. The second challenge is common in realist evaluation and relates to how to choose from different potentially interesting theoretical frameworks. We identified relevant and empirically tested theories from behavioural science that may be helpful in our study. We will test them in 3 settings by exploring the multilevel factors that influence acceptability and adherence of this new paediatric Antiretroviral (ARV) formulation.

Abstract
BACKGROUND Smartphones with programmable apps may offer innovative interactive interventions for improving adherence among people living with HIV with substance use problems. METHODS This pilot randomized controlled trial sought to primarily determine the usability and feasibility of using a smartphone-based intervention called Heart2HAART as an adjunct to directly observed treatment with adherence counseling compared to directly observed treatment with adherence counseling alone among those with HIV and a history of substance use over a three-month time frame. Participants in the Heart2HAART condition completed an additional survey on usability and acceptability. Adherence was measured using unannounced pill counts assessed via a phone call. RESULTS Twenty-eight participants were randomized to receive Heart2HAART (n = 19) or control (n = 9). All were receiving either weekly (n = 9) or daily (n = 19) observed treatment. Among those randomized to Heart2HAART, 63.2% reported no difficulty using the Heart2HAART smartphone application and 94.7% responded that the medication reminders did not interfere negatively with their activities. On average participants used Heart2HAART application 56.8 times over the three-month trial. In analyses adjusting for age, there was no difference in adherence to HAART medication between the Heart2HAART and control group as evaluated by the random pill count assessment (P = .29). CONCLUSIONS Heart2HAART was feasible to use during a three-month pilot trial. Future studies may evaluate a more tailored approach, with more robust contingency management.

Abstract
INTRODUCTION Two-thirds of people living with HIV (PLWH) show sub-optimal adherence to antiretroviral therapy (ART) and one-third engages in risky sex. Both non-adherence and risky sex have been associated with emotional distress and impulsivity. To allay distress and lessen impulsivity, mindfulness training (MT) can be helpful. In this trial, we will investigate the utility of phone-delivered MT for PWLH. The primary outcomes comprise feasibility and acceptability of phone-delivery; secondary outcomes are estimates of efficacy of MT on adherence to ART and safer sexual practices as well as on their hypothesized antecedents. METHODS/DESIGN Fifty participants will be enrolled in this parallel-group randomized clinical trial (RCT). Outpatients recruited from an HIV treatment clinic will be randomized (1:1 ratio) to either MT or to an attention-control intervention; both interventions will be administered during 8 weekly phone calls. ART adherence (self-reported measure and unannounced phone pill counts), sexual behavior (self-reports and biomarkers), mindfulness, depression, stress, and impulsivity will be measured at baseline, post-intervention, and 3months post-intervention. CONCLUSIONS MT has great potential to help PLWH to manage stress, depressive symptoms, and impulsivity. Positive changes in these antecedents are expected to improve safer sex practices and ART adherence. If results from this exploratory trial support our hypotheses, we will conduct a large RCT to test (a) the efficacy of MT on ART adherence and safer sex practices and (b) the hypothesis that improved ART adherence and safer sex will reduce viral load, and decrease the incidence of sexually transmitted infections, respectively.

Abstract
Antiretroviral therapy (ART) has transformed HIV into a manageable illness. However, high levels of adherence must be maintained. Lack of access to basic resources (food, transportation, and housing) has been consistently associated with suboptimal ART adherence. Moving beyond such direct effects, this study takes a hierarchical resources approach in which the effects of access to basic resources on ART adherence are mediated through interpersonal resources (social support and care services) and personal resources (self-efficacy). Participants were 915 HIV-positive men and women living in Atlanta, GA, recruited from community centers and infectious disease clinics. Participants answered baseline questionnaires, and provided prospective data on ART adherence. Across a series of nested models, a consistent pattern emerged whereby lack of access to basic resources had indirect, negative effects on adherence, mediated through both lack of access to social support and services, and through lower treatment self-efficacy. There was also a significant direct effect of lack of access to transportation on adherence. Lack of access to basic resources negatively impacts ART adherence. Effects for housing instability and food insecurity were fully mediated through social support, access to services, and self-efficacy, highlighting these as important targets for intervention. Targeting service supports could be especially beneficial due to the potential to both promote adherence and to link clients with other services to supplement food, housing, and transportation. Inability to access transportation had a direct negative effect on adherence, suggesting that free or reduced cost transportation could positively impact ART adherence among disadvantaged populations.

Abstract
Few self-report measures of medication adherence have been rigorously developed and validated against electronic drug monitoring (EDM). Assess the validity of the 3-item self-report scale by comparing it with a contemporaneous EDM measure. We conducted an observational study in which adherence assessments were done monthly for up to 4 months for 81 patients with HIV who were taking antiretroviral medications. We report results for both HIV antiretroviral medications, and also for other, non-HIV-related medications. Raw and calibrated self-report adherence measures, electronic drug monitoring adherence measures, and sociodemographic variables. The mean age of patients was 46 years, 37 % were female, 49 % had some education beyond high school, 22 % were Black, and 22 % were Hispanic. Cronbach's alphas for the 3-item scale for HIV and non-HIV medications were 0.83 and 0.87, respectively. The mean differences (raw/uncalibrated self-report scale minus EDM) for HIV and non-HIV medications were 7.5 and 5.2 points on a 100-point scale (p < 0.05 for both). Pearson correlation coefficients between the calibrated 3-item scale and the EDM for HIV and non-HIV medications were 0.47 and 0.59, respectively. The c-statistics for the ROC curves for the calibrated scale, using cut-offs of 0.8 and 0.9 for the EDM gold standard measure to define non-adherence, were between 0.74 and 0.76 for HIV and non-HIV medications. This 3-item adherence self-report scale showed good psychometric characteristics and good construct validity when compared with an EDM standard, for both HIV and non-HIV medications. In clinical care it can be a useful first-stage screener for non-adherence. In clinical research and quality improvement settings it can be a useful tool when more complex and expensive methods such as EDM or pharmacy claims are impractical or unavailable.

Abstract
BACKGROUND Nonadherence to immunosuppressant medication is a prevalent practice among kidney transplant recipients and has been associated with increased risk for graft failure and economic burden. The aim of this pilot study was to test whether a culturally sensitive cognitive-behavioral adherence promotion program could significantly improve medication adherence to tacrolimus prescription as measured by telephone pill counts among kidney transplant recipients. METHODS Thirty-three adult transplant recipients were less than 98% adherent to tacrolimus prescription based on 3 telephone pill counts and were randomized either to the 2-session cognitive-behavioral adherence promotion program or to standard care. The curriculum was developed from an iterative process with transplant recipients into a 2-session group program that provided psychoeducation, addressed barriers to adherence, fostered motivation to improve adherence behavior, and discussed cultural messages on adherence behavior. RESULTS The intervention group displayed significantly higher levels of adherence when compared to the control group (t = 2.2, p = 0.04) and. similarly, when the amount of change was compared between the groups, the intervention group showed more change than the control condition (F (22,1) = 12.005, p = 0.003). Tacrolimus trough concentration levels were used as a secondary measure of adherence and, while there were no significant between-group differences for mean trough concentration levels, the variability in the trough levels did significantly decrease over time indicating more consistent pill-taking behavior in the intervention group. CONCLUSIONS There is preliminary support for the pilot program as a successful intervention in helping patients with their immunosuppressant medication.

Sexual Behaviors and Transmission Risks Among People Living with HIV: Beliefs, Perceptions, and Challenges to Using Treatments as Prevention. ARCHIVES OF SEXUAL BEHAVIOR 2016; 45:1421-30. [PMID: 26292837 PMCID: PMC4761529 DOI: 10.1007/s10508-015-0559-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2014] [Revised: 04/29/2015] [Accepted: 04/29/2015] [Indexed: 05/15/2023]
Abstract
Antiretroviral therapy (ART) improves the health of people living with HIV and can reduce infectiousness, preventing HIV transmission. The potential preventive benefits of ART are undermined by beliefs that it is safe to have condomless sex when viral load is below levels of detection (infectiousness beliefs and risk perceptions). In this study, we hypothesized that infectiousness beliefs and HIV transmission risk perceptions would prospectively predict people living with HIV engaging in more condomless sex with HIV-negative and unknown HIV status sex partners. Sexually active HIV-positive men (n = 538, 76 %) and women (n = 166, 24 %) completed computerized interviews of sexually transmitted infection (STI) symptoms and diagnoses, unannounced pill counts for medication adherence, medical chart-abstracted HIV viral load, and 28 daily cell-phone-delivered prospective sexual behavior assessments. Results showed that a total of 313 (44 %) participants had engaged in condomless sex with HIV-negative/unknown status sex partners, and these individuals demonstrated higher rates of STI symptoms and diagnoses. Two-thirds of participants who had condomless sex with HIV-negative/unknown status partners had not disclosed their HIV status. Multivariable logistic regression models showed that beliefs regarding viral load and HIV infectiousness and perceptions of lower risk of HIV transmission resulting from HIV viral suppression predicted condomless sex with potentially uninfected partners over and above sex behaviors with HIV-positive partners and STI symptoms/diagnoses. Interventions that address HIV status disclosure and aggressively treat STI in sexually active people living with HIV should routinely accompany the use of HIV treatments as prevention.

Race-based medical mistrust, medication beliefs and HIV treatment adherence: test of a mediation model in people living with HIV/AIDS. J Behav Med 2016; 39:1056-1064.

Abstract
Race-based medical mistrust significantly predicts non-adherence to antiretroviral therapy (ART) in people living with HIV. The current study builds on previous research that shows beliefs about medication necessity (i.e., "My medicines protect me from becoming worse") and concerns (i.e., "Having to take my medicines worries me") mediate the association between race-based medical mistrust and medication adherence. Racial and ethnic minority men and women living with HIV and receiving ART (N = 178) in a southern US city completed computerized measures of demographic and health characteristics, telephone interviews of race-based medical mistrust and medication beliefs, and unannounced phone-based pill counts for ART adherence. Multiple mediation modeling showed that medical mistrust is related to medication necessity and concerns beliefs and ART adherence. Furthermore, medication necessity beliefs predicted ART adherence. The indirect effect of medical mistrust on adherence through medication necessity beliefs was also significant. Results confirm that medication necessity beliefs, although not concerns beliefs, mediate the association between medical mistrust and ART adherence. Medication necessity beliefs offer a viable target for interventions to improve ART adherence in the context of mistrust that patients may have for medical providers and health care systems.

Abstract
Background Evidence-based psychosocial interventions for addictions and related conditions such as cognitive behavioral therapy (CBT) are underutilized. Obstacles to implementation of CBT in clinical settings include limited availability of quality training, supervision, and certification in CBT for clinicians; high rates of clinician turnover and high caseloads; and limited qualifications of the workforce to facilitate CBT expertise. Objective Mobile phone–based delivery of CBT, if demonstrated to be feasible and effective, could be transformative in broadening its application and improving the quality of addiction treatment. No experimental interventions that deliver CBT targeting both drug use and medication adherence using text messaging have been previously reported; as such, the objective of this study is to develop and test an SMS-based treatment program for HIV-positive adults with comorbid substance use disorders. Methods With user input, we developed a 12-week CBT-based text messaging intervention (TXT-CBT) targeting antiretroviral (ART) adherence, risk behaviors, and drug use in a population of HIV-infected substance users. Results The intervention has been developed and is presently being tested in a pilot randomized clinical trial. Results will be reported later this year. Conclusions This investigation will yield valuable knowledge about the utility of a cost-effective, readily deployable text messaging behavioral intervention for HIV-infected drug users.

Abstract
Women with HIV in the United States cope with multiple traumas that influence adherence to antiretroviral therapy (ART) and well-being. Narrative themes from three life turning points and a projective story task were compared for two groups of women with HIV (HIV well-managed vs. HIV not well-managed, matched on demographics and narrative word count) to understand predictors of successful outcomes. The well-managed group (n = 10) was virally suppressed and reported ≥95% ART adherence; the not well-managed group (n = 10) had detectable viral load and reported <95% ART adherence. Women were predominantly African American with low socioeconomic status and averaged 46.51 years. A three-stage coding process (with coders blind to group status in stages 1 and 2) involved (1) line by line thematic analyses that generated 155 subthemes reflecting six content areas (interpersonal relationships; culture and community; sense of self; relationship to past, present, and future experiences; self-care; and motivators for change); (2) absence/presence of the 155 subthemes was compared for the two groups; the frequency of 37 subthemes was found to significantly differ; and (3) the 37 differentiating subthemes were conceptually integrated, revealing that the well-managed group's narratives more frequently reflected (a) mutuality (growth-fostering relationships involving reciprocal care and empathy); (b) self-awareness (recognition of personal strengths and weaknesses and multiple factors contributing to life choices and trajectories); and (c) self-efficacy (active coping, self-advocacy, and utilizing resources). Implications for treatment and interconnections among themes are discussed, emphasizing the factors that enable women to care for themselves and others.

Abstract
BACKGROUND Drug use poses significant challenges to medical management of HIV infection. Although most research has focused on the influence of intoxication on unintentional adherence to HIV treatment, drug use may also lead to intentional nonadherence, particularly when individuals believe that mixing medications with drugs is harmful. This study examined whether interactive toxicity beliefs predict nonadherence to antiretroviral therapy (ART) over a prospective period of adherence monitoring. METHODS Men and women living with HIV who screened positive for drug use and were being treated with ART (n = 530) completed computerized self-interviews and 3 prospective unannounced pill counts to measure ART adherence and provided urine specimens for drug screening and HIV viral load results from medical records. RESULTS Results showed that 189 (35%) participants indicated that they intentionally miss their ART when they are using drugs. These participants also reported common beliefs regarding the perceived hazards of mixing HIV medications with alcohol and other drugs. Multivariable models controlled for demographic and health characteristics and frequency of alcohol use showed that intentional nonadherence predicted poorer ART adherence over the prospective month and also predicted poorer treatment outcomes as indexed by unsuppressed HIV viral load. CONCLUSIONS These findings extend previous research to show that interactive toxicity beliefs and intentional nonadherence play a significant role in medication nonadherence for a substantial number of people living with HIV and should be actively addressed in HIV clinical care.

Abstract
Limited health literacy has been shown to contribute to poor adherence to antiretroviral therapy (ART) in people living with HIV/AIDS. Given the mixed results of previous interventions for people with HIV and low health literacy, investigating possible targets for improved adherence is warranted. The present study aims to identify the correlates of optimal and suboptimal outcomes among participants of a recent skills-based medication adherence intervention. This secondary analysis included 188 men and women living with HIV who had low health literacy and who had complete viral load data. Adherence was assessed by unannounced pill count and follow-up viral loads were assessed by blood draw. Results showed that higher levels of health literacy and lower levels of alcohol use were the strongest predictors of achieving HIV viral load optimal outcomes. The interplay between lower health literacy and alcohol use on adherence should be the focus of future research.

Abstract
BACKGROUND People living in poverty face multiple structural challenges to medication adherence including lack of transportation, inadequate housing and food insecurity. The degree to which individuals' motivations to remain adherent may overcome structural barriers has received limited attention. PURPOSE To examine whether medication necessity and concerns beliefs predict antiretroviral therapy (ART) adherence over and above structural adherence barriers associated with poverty. METHODS People living with HIV in a southern US city (N = 942) completed computerised interviews, an objective measure of adherence and HIV viral suppression obtained from medical records. Hierarchical logistic regression models were constructed to examine demographic and illness characteristics, structural barriers, mental health, substance use and medication necessity and concerns beliefs as predictors of ART adherence. RESULTS In multivariable models, current drug use and medication necessity and concerns beliefs predicted treatment adherence over and above demographic, health, mental health and structural factors. CONCLUSIONS Medication beliefs are proximal and powerful motivating factors that predict adherence. Adherence interventions should directly address medication beliefs in developing strategies to manage barriers facing people with HIV living in poverty.
