Effectiveness of an intervention to improve ART adherence among men who have sex with men living with HIV: a randomized controlled trial in three public HIV clinics in Mexico. AIDS Care 2024; 36:816-831. [PMID: 38422450 DOI: 10.1080/09540121.2023.2299322] [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: 05/26/2023] [Accepted: 12/18/2023] [Indexed: 03/02/2024]
Abstract
We conducted a parallel-group randomized controlled trial in three HIV clinics in Mexico to evaluate a user-centred habit-formation intervention to improve ART adherence among MSM living with HIV. We randomized 74 participants to the intervention group and 77 to the control group. We measured adherence at one, four, and ten months through medication possession ratio and self-reported adherence. Additionally, we measured viral load, CD4 cell count, major depression disorder symptoms, and alcohol and substance use disorder at baseline, fourth and tenth months. We found no statistically significant effect on adherence between groups. However, the intervention demonstrated positive results in major depression disorder symptoms (21% vs. 6%, p = 0.008) and substance use disorder (11% vs. 1%, p = 0.018) in the fourth month. The latter is relevant because, in addition to its direct benefit, it might also improve the chances of maintaining adequate adherence in the long term. This trial was retrospectively registered at ClinicalTrials.gov (trial number NCT03410680) on 8 January 2018.Trial registration: ClinicalTrials.gov identifier: NCT03410680.

Abstract
Oral PrEP's effectiveness relies on adequate adherence during periods of substantial HIV risk. Since most PrEP users will miss doses, understanding predictors within participants can help to explain adherence. We used a cross-sectional, within-participant design with 67 gay, bisexual, and other men who have sex with men taking PrEP daily. Using a questionnaire, informed by the Information Motivation Behavioral Skills Model, participants were asked about an adherent and a non-adherent episode. PrEP non-adherence was associated with non-normality of the day (p < .001), being out of the home (p < .001), weekend days (p = .01), having company (p = .02), using substances (p = 0.02), not using reminders (p = .03), lower PrEP information (p = .04), lower behavioural skills (p < .001) and less positive affect (p = .002). PrEP adherence assessment could focus on situational variations, supporting the construction of alternative strategies to facilitate adherence in these situations.

Abstract
We use Fawcett and DeSanto-Madeya's framework to critique Fisher and Fisher's information-motivation-behavioral skills model and determine its usefulness and applicability for nursing. Our analysis and evaluation show that the model is a parsimonious and useful situation-specific theory for guiding nursing research and practice because it shows good fit with the nursing context, has social and theoretical significance, and exhibits empirical and pragmatic adequacy. More consistency in using terms referring to each concept would help to improve the model's internal consistency. The model's testability could also be improved by measuring health outcomes (eg, viral load or CD4 count) in future research.

Abstract
This pilot study tested the feasibility of Lantern program, an adherence program to HIV medications using WhatsApp, a secure social media messaging application from Meta, for a smartphone-based platform to enhance medication-taking adherence of antiretroviral therapy among people living with HIV in Indonesia. Thirty participants were recruited for this 8-week study. We recruited persons if they had taken antiretroviral therapy for at least 3 months prior to the study, had a smartphone, Internet access, and could use Lantern with WhatsApp. Here, we report the results from the focus group discussions, with the participants evaluating the qualitative aspects of the experiences. The WhatsApp platform was found to be safe, practical, and relatively inexpensive and provided confidentiality for the participants. Three themes emerged from the focus groups: the study motivated participants to take their antiretroviral therapy medications on time, they still set medication reminder alarms, and being in the study made them feel supported. The Lantern program indicated good feasibility and acceptability for adherence to antiretroviral therapies among people living with HIV. Future research should examine on how community organizations and healthcare providers can take advantage of the WhatsApp program to improve adherence to antiretroviral therapies.

Abstract
BACKGROUND Mobile Health ("mHealth") interventions have shown promise in improving HIV treatment outcomes for stigmatized populations. This paper presents the findings from a randomized controlled trial to assess the efficacy, participant-level feasibility and acceptability of a theory-informed mHealth intervention, Motivation Matters!, designed to improve viral suppression and ART adherence among HIV-seropositive women who engage in sex work in Mombasa, Kenya. METHODS A total of 119 women were randomized between the intervention and standard of care control. The primary outcome examined viral suppression (≤ 30 copies/mL) six months following ART initiation. ART adherence was assessed monthly using a visual analogue scale. Participant-level feasibility was measured through response rates to study text messages. Acceptability was assessed through qualitative exit interviews. RESULTS Six months following treatment initiation, 69% of intervention and 63% of control participants were virally suppressed (Risk Ratio [RR] = 1.09, 95% Confidence Interval [95% CI] (0.83, 1.44). Among women who were viremic at baseline and endorsed engagement in sex work, 74% of women in the intervention arm compared with 46% of women in the control arm achieved viral suppression at month six RR = 1.61, 95% CI (1.02, 2.55). Adherence was higher in intervention versus control participants every month. All participants responded to at least one message, and there was a 55% overall response rate to intervention text messages. Qualitative exit interviews suggested high acceptability and perceived impact of the intervention. CONCLUSION The improvements in ART adherence and viral suppression, combined with encouraging data on feasibility and acceptability, provides preliminary evidence that Motivation Matters! could support ART adherence and viral suppression in women who engage in sex work. TRIAL REGISTRATION This trial was registered with ClinicalTrials.gov (NCT02627365, 10/12/2015; http://clinicaltrials.gov ).

Abstract
The Information-Motivation-Behavioral Skills (IMB) Model has been used to understand adherence to medications and intentions to uptake pre-exposure prophylaxis (PrEP) to prevent HIV infection. In the current study, the IMB Model was used to understand factors that predict adherence to PrEP among a community-based cohort of 204 Black men who have sex with men (MSM) and transgender women (TGW) using structural equation modeling. PrEP motivation was directly associated with PrEP behavioral skills (β = 0.320, p = 0.009), and PrEP behavioral skills were directly associated with PrEP adherence (β = 0.416, p = 0.001). PrEP knowledge and PrEP motivation were not associated with PrEP adherence, directly or indirectly. The analysis identified intervenable factors that predicted PrEP adherence. Screening for motivation and behavioral skills could be used to identify where additional support to improve PrEP adherence is needed, or whether to offer alternative PrEP modalities or delivery strategies.

Abstract
The Information-Motivation-Behavioral skills (IMB) model of antiretroviral therapy (ART) adherence was applied in people living with HIV/AIDS in Shanghai, China to understand how adherence-related information, motivation and behavioral skills would affect ART adherence. The LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire (LW-IMB-AAQ) was translated into Chinese and used. The IMB model was then implemented by testing standardized path estimates with standard model fitness indices in the participants. 426 participants from 11 community centres in Putuo district of Shanghai were recruited, of which 95.3% reported a high level of adherence (>95% adherence). The fitness indices of the final adjusted model were χ2 = 6.110, df = 7, p = 0.527(>0.05), CFI = 1.000(>0.9) and RMSEA = 0.000 (<0.08). In the model, information, which was separated into two sections (the perceived effect of ART on health and knowledge about ART medication), had an indirect effect on the ART adherence through behavioral skills, while motivation did not have such an effect. Neither information nor motivation had a direct effect on ART adherence. In addition, motivation was related to the two sections of information. The feasibility of the IMB model of ART adherence is verified by its application to predictive of adherence-related behaviors among HIV+ patients in this study.

Abstract
Abstract Background Young adults with perinatally acquired HIV (PAH) face several challenges, including adhering to antiretroviral therapy (ART), managing the risk of onward HIV transmission and maintaining positive well-being. Sharing one’s HIV status with others (onward HIV disclosure) may assist with these challenges by facilitating emotional and practical support. Rates of HIV status sharing are, however, low in this population. There are no existing interventions focused on sharing one’s HIV status for young adults living with PAH. The HEADS-UP study is designed to develop and test the feasibility of an intervention to help the sharing of HIV status for young adults with PAH. Methods The study is a 30-month multi-site randomised feasibility study across both a high-income/low-HIV prevalence country (UK) and a low-income/high-HIV prevalence country (Uganda). Phase 1 (12 months) will involve developing the intervention using qualitative interviews with 20 young people living with PAH (ten in the UK—18 to 29 years; ten in Uganda—18 to 25 years), 20 of their social network (friends, family, sexual partners as defined by the young person; ten in the UK, ten in Uganda) and ten professionals with experience working with young adults with PAH (five in the UK, five in Uganda). Phase 2 (18 months) involves conducting a randomised feasibility parallel group trial of the intervention alongside current standard of care condition in each country (main study) with 18- to 25-year olds with PAH. A sample size of 94 participants per condition (intervention or standard of care; 188 participants in total: 47 in each condition in each country) with data at both the baseline and 6-month follow-up time points, across UK and Ugandan sites will be recruited. Participants in the intervention condition will also complete measures immediately post-intervention. Face-to-face interviews will be conducted with ten participants in both countries immediately post-intervention and at 6-month follow-up (sub-study). Discussion This study will be the first trial that we are aware of to address important gaps in understanding acceptable and feasible ways of delivering HIV status sharing support for young people living with PAH.

Abstract
Background Men who have sex with men (MSM) are disproportionally affected by HIV in China. ‘Treatment as Prevention’ is a promising strategy for HIV prevention but requires adequate adherence. Mobile health (mHealth) may be an acceptable and feasible approach for service delivery, but there is little evidence supporting mHealth intervention for improving antiretroviral treatment adherence among HIV-infected MSM in low- and middle-income countries, including China. This study will aim to develop a smartphone application-based case-management service and compare its efficacy to standard care with regards to adherence, CD4, HIV viral load and psychosocial outcomes among MSM patients in Guangzhou, China. Methods A non-blinded 1:1 parallel-group randomised controlled trial will be conducted in Guangzhou Eighth People’s Hospital, with 300 MSM enrolled in each arm. Eligible MSM who are newly initiating ART will be randomly assigned to an intervention group (standard-of-care case management plus mHealth intervention) or a control group (standard-of-care case management). The development of the mHealth intervention will be based on the information–motivation–behavioural skills theory of ART adherence, and comprise four components: educational articles, one-to-one online communication with case managers, support-service information and hospital-visit reminders. Outcome measures will be collected at baseline and at months 1, 3, 6, and 12. The primary outcomes will be ART adherence and CD4 count at month 6. Secondary outcomes include HIV RNA, sexual behaviours, mental health status, illness perceptions, and quality of life. χ2 test and t-test will be used for between-group comparisons. Intervention effects will be evaluated using General estimating equation performed by SAS 9.0, on the principle of intention-to-treat. Structural equation modelling will be used to test potential mechanisms of intervention effect. Discussion This study is the first to explore the efficacy of mHealth intervention in the case management services targeted at HIV-infected MSM in low-and middle-income countries. Once proven effective, the innovative mHealth service could be integrated into the routine case management of PLWH. as well as be tailored to the patient management service for other chronic conditions.

Reliability and Validity of the LifeWindows Information-Motivation-Behavioral Skills Antiretroviral Therapy Adherence Questionnaire Among HIV+ Patients in Shanghai. Patient Prefer Adherence 2020; 14:507-515. [PMID: 32184577 PMCID: PMC7062391 DOI: 10.2147/ppa.s234041] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Accepted: 02/01/2020] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE The purpose of this article was to examine the validity and reliability of the LifeWindows Information-Motivation-Behavioral Skills Antiretroviral Therapy (ART) Adherence Questionnaire (LW-IMB-AAQ) among HIV+ patients in Shanghai. METHODS We surveyed 426 HIV+ patients in Shanghai's Putuo District to examine the validity and reliability of the questionnaire. The questionnaire includes self-reported demographic characteristics, the modified version of the Community Programs for Clinical Research on AIDS Antiretroviral Medication Self-Report (CPCRA) and LW-IMB-AAQ. CPCRA was used to calculate ART adherence. LW-IMB-AAQ, including the information section, the motivation section and the behavioral skills section, was used to analyze patients' ART adherence. We analyzed data by means, standard deviation, critical ratio, and item-total correlation. Reliability was assessed by internal consistency, split-half reliability, and test-retest reliability. Validity was assessed by exploratory factor analysis (EFA), confirmatory factor analysis (CFA), convergent validity and discriminant validity. RESULTS Item analysis showed that except for motivation item 1, all items were acceptable. For reliability, Cronbach's alpha coefficients for the three sections and the total scale were all higher than 0.7, with interclass correlation coefficients (ICC) all higher than 0.6 (p<0.001). The Spearman-Brown coefficient for the total scale was 0.825. For validity, results showed that the information section could be divided into two subscales, motivation section and behavioral skills section could be divided into three and two subscales, respectively. The final model demonstrated good validity (p=0.471, χ 2/df=0.960, CFI=1.000, GFI=0.994 and RMSEA<0.001) without motivation item 4. CONCLUSION Excluding motivation items 1 and 4, the LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire (LW-IMB-AAQ) demonstrated good validity and reliability among HIV+ patients in Shanghai.

[PMID: 29356390 PMCID: PMC5810329 DOI: 10.1002/jia2.25066] [Citation(s) in RCA: 51] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2017] [Accepted: 12/19/2017] [Indexed: 12/15/2022] Open
Abstract
INTRODUCTION Optimal adherence to antiretroviral therapy is closely related with suppression of the HIV viral load in plasma, slowing disease progression and decreasing HIV transmission rates. Despite its importance, the estimated proportion of people living with HIV in Latin America and the Caribbean with optimal adherence has not yet been reported in a meta-analysis. Moreover, little is known of the factors leading to poor adherence which may be setting-specific. We present a pooled estimate of adherence to antiretroviral therapy (ART) of people living with HIV in Latin America and Caribbean, report the methods used to measure adherence and describe the factors associated with poor adherence among the selected studies. METHODS We electronically searched published studies up to July 2016 on the PubMed, Web of Science and Virtual Health Library (Latin America and the Caribbean Regional Portal); considering the following databases: MEDLINE, LILACS, PAHO and IBECS. Two independent reviewers selected and extracted data on ART adherence and study characteristics. Pooled estimate of adherence was derived using a random-effects model. Risk of bias in individual studies was assessed independently by two investigators using the Risk of Bias Assessment tool for Non-randomized Studies (RoBANS). RESULTS AND DISCUSSION The meta-analysis included 53 studies published between 2005 and 2016, which analysed 22,603 people living with HIV in 25 Latin America and Caribbean countries. Overall adherence in Latin America and Caribbean was 70% (95% CI: 63-76; I2 = 98%), similar to levels identified by studies conducted in high-income regions. Self-report was the most frequently used method to measure adherence. Subgroup analysis showed that adherence was higher for the shortest recall time frame used, as well as in countries with lower income level, Gross National Income (GNI) per capita and Human Development Index (HDI). Studies reported diverse adherence barriers, such as alcohol and substance misuse, depression, unemployment and pill burden. CONCLUSIONS Our study suggests that adherence to ART in Latin America and Caribbean may be below the sufficient levels required for a successful long-term viral load suppression.

Abstract
Background The provision of Anti-Retroviral Therapy (ART) was started in Myanmar in 2005 in collaboration with the National AIDS Program and the private sector. Successful clinical management of HIV-infected patients is subject to optimal adherence. The aim of the study was to determine the prevalence of adherence to ART and identify factors associated with non-adherence to ART among HIV infected adults registered in a private sector setting in Mon State, Myanmar. Methods This cross-sectional study was conducted with adults living with HIV receiving ART at an HIV outpatient clinic between April and May 2016. A total of three hundred People Living with HIV(PLHIV) were interviewed using a pretested and structured questionnaire. The 30 days Visual Analog Scale (VAS) adherence instrument was used to assess the level of adherence. Multivariable logistic regression analysis was used to determine factors associated with non-adherence to ART. Results Among 300 patients (male 37.7% and female 62.3%, with a mean age of 41.3 years, standard deviation 8.7), 84% reported ≥95% adherence to ART in the past month. Among 16% of those reporting non-adherence, major reasons for skipping the medication were being busy (23%), being away from home (17.7%) and being forgetful (12.3%). In multivariable logistic rgeression, low behavioural skills on ART adherence (OR = 0.31, 95% CI: 0.10-0.94), tobacco use (OR = 3.22, 95% CI:1.28-8.12), having disclosed their HIV status (OR = 0.07, 95% CI: 0.01-0.69), having a partner who was not on ART (OR = 4.25, 95% CI: 1.70-10.64) and among men, having erectile dysfunction (OR = 15.14, 95% CI: 1.41-162.66) were significant associated with ART non-adherence. Conclusion Non-adherence to ART was associated with individual moderating factors and behavioral skills. Priority measures such as addressing risk behaviour and behavioural change communication tailored to individual patients’ lifestyles requires comprehensive interventions to improve adherence.

Exploring 'generative mechanisms' of the antiretroviral adherence club intervention using the realist approach: a scoping review of research-based antiretroviral treatment adherence theories. BMC Public Health 2017; 17:385. [PMID: 28472938 PMCID: PMC5418699 DOI: 10.1186/s12889-017-4322-8] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2016] [Accepted: 04/27/2017] [Indexed: 01/30/2023] Open
Abstract
Background Poor retention in care and non-adherence to antiretroviral therapy (ART) continue to undermine the success of HIV treatment and care programmes across the world. There is a growing recognition that multifaceted interventions – application of two or more adherence-enhancing strategies – may be useful to improve ART adherence and retention in care among people living with HIV/AIDS. Empirical evidence shows that multifaceted interventions produce better results than interventions based on a singular perspective. Nevertheless, the bundle of mechanisms by which multifaceted interventions promote ART adherence are poorly understood. In this paper, we reviewed theories on ART adherence to identify candidate/potential mechanisms by which the adherence club intervention works. Methods We searched five electronic databases (PubMed, EBSCOhost, CINAHL, PsycARTICLES and Google Scholar) using Medical Subject Headings (MeSH) terms. A manual search of citations from the reference list of the studies identified from the electronic databases was also done. Twenty-six articles that adopted a theory-guided inquiry of antiretroviral adherence behaviour were included for the review. Eleven cognitive and behavioural theories underpinning these studies were explored. We examined each theory for possible ‘generative causality’ using the realist evaluation heuristic (Context-Mechanism-Outcome) configuration, then, we selected candidate mechanisms thematically. Results We identified three major sets of theories: Information-Motivation-Behaviour, Social Action Theory and Health Behaviour Model, which explain ART adherence. Although they show potential in explaining adherence bebahiours, they fall short in explaining exactly why and how the various elements they outline combine to explain positive or negative outcomes. Candidate mechanisms indentified were motivation, self-efficacy, perceived social support, empowerment, perceived threat, perceived benefits and perceived barriers. Although these candidate mechanisms have been distilled from theories employed to explore adherence to ART in various studies, the theories by themselves do not provide an explanatory model of adherence based on the realist logic. Conclusions The identified theories and candidate mechanisms offer possible generative mechanisms to explain how and why patients adhere (or not) to antiretroviral therapy. The study provides crucial insights to understanding how and why multifaceted adherence-enhancing interventions work (or not). These findings have implications for eliciting programme theories of group-based adherence interventions such as the adherence club intervention.

Abstract
Evidence from recent pre-exposure prophylaxis (PrEP) trials has demonstrated its safety and efficacy in significantly reducing the risk of HIV acquisition for those who are at considerable risk of acquiring HIV infection. With a rapid increase in the amount of research on the efficacy of PrEP for HIV prevention, complementary research on the willingness to use PrEP has grown, especially among MSM, but limited research has been focused among people who use drugs (PWUD). As part of the formative process, we utilized the information-motivation-behavioral skills (IMB) model of health behavior change to characterize and guide intervention development for promoting willingness to use PrEP among high-risk PWUD. The analysis included 400 HIV-negative high-risk PWUD enrolled in a community-based methadone maintenance treatment who reported drug- and/or sex-related HIV risk behaviors in the past 6-months. Analyses revealed support for the IMB model as PrEP-related behavioral skills were found to mediate the influence of PrEP-related information and motivation on willingness to use PrEP. The results provide evidence as to the utility of the IMB model to increase willingness to use PrEP among high-risk PWUD. It therefore makes an important contribution to our understanding of the applicability of theoretically-grounded models of willingness to use PrEP among high-risk PWUD, who are one of the key risk populations who could benefit from the use of PrEP.
