Abstract
Objective:Health disparities are evident for Black Americans with HIV disease, who are disproportionally affected by the epidemic in the United States. The current study investigated whether the higher rates of neurocognitive impairment in Black Americans with HIV disease may be at least partly attributable to health literacy, which is a potentially modifiable factor. Method: Participants were 61 White and 25 Black participants (ages 27-70) with HIV disease who were enrolled in studies at an urban academic center in Southern California. Neurocognitive function was assessed by an age-adjusted global score from the Cogstate battery. Health literacy was measured by a composite score derived from the Rapid Estimate of Adult Literacy in Medicine, Newest Vital Sign, and 3-Brief. Results: Bootstrap confidence interval mediation analyses showed that health literacy was a significant mediator of the relationship between race and neurocognition; that is, there were no direct ethnoracial differences in neurocognition after accounting for health literacy. A follow-up model to confirm the directionality of this association demonstrated that neurocognition was not a significant mediator of the relationship between race and health literacy. Conclusions: Low health literacy may contribute to the higher rates of neurocognitive impairment for Black Americans with HIV disease. Future studies might examine the possible mechanism of this mediating relationship (e.g., access to health information, health behaviors, socioeconomics) and determine whether culturally tailored interventions that improve health literacy also confer broader brain health benefits for Black Americans with HIV disease.

When healthcare providers are supportive, 'I'd rather not test alone': Exploring uptake and acceptability of HIV self-testing for youth in Zimbabwe - A mixed method study. J Int AIDS Soc 2021; 24:e25815.

Abstract
INTRODUCTION In sub-Saharan Africa, less than half of young people know their HIV status. HIV self-testing (HIVST) is a testing strategy with the potential to offer privacy and autonomy. We aimed to understand the uptake and acceptability of different HIV testing options for youth in Harare, Zimbabwe. METHODS This study was nested within a cluster randomized trial of a youth-friendly community-based integrated HIV and sexual and reproductive health intervention for youth aged 16-24 years. Three HIV testing options were offered: (1) provider-delivered testing; (2) HIVST on site in a private booth without a provider present; and (3) provision of a test kit to test off site. Descriptive statistics and proportions were used to investigate the uptake of HIV testing in a client sample. A focus group discussion (FGD) with intervention providers alongside in-depth interviews, paired interviews and FGDs with a selected sample of youth clients explored uptake and acceptability of the different HIV testing strategies. Thematic analysis was used to analyse the qualitative data. RESULTS Between April and June 2019, 951 eligible clients were tested for HIV: 898 (94.4%) chose option 1, 30 (3.25%) chose option 2 and 23 (2.4%) chose option 3. Option 1 clients cited their trust in the service and a desire for immediate counselling, support and guidance from trusted providers as the reasons for their choice. Young people were not confident in their expertise to conduct HIVST. Concerns about limited privacy, confidentiality and lack of support in the event of an HIV-positive result were barriers for off-site HIVST. CONCLUSIONS In the context of supportive, trusted and youth-friendly providers, youth clients overwhelmingly preferred provider-delivered HIV testing over client-initiated HIVST or HIVST off site. This highlights the importance of listening to youth to improve engagement in testing. While young people want autonomy in choosing when, where and how to test, they do not want to necessarily test on their own. They desire quality in-person counselling, guidance and support, alongside privacy and confidentiality. To increase the appeal of HIVST for youth, greater provision of access to private spaces is required, and accessible pre- and post-test counselling and support may improve uptake.

Abstract
Introduction: The rapid development of coronavirus disease 2019 (COVID-19) into a pandemic required people to quickly acquire, evaluate, and apply novel complex health-related information about the virus and transmission risks. This study examined the potentially unique and synergistic roles of individual differences in neurocognition and health literacy in the early uptake and use of COVID-19 public health information.Method: Data were collected between April 23 and 21 May 2020, a period during which 42 out of 50 states were under a stay-at-home order. Participants were 217 healthy adults who completed a telephone-based battery that included standard tests of neurocognition, health literacy, verbal IQ, personality, and anxiety. Participants also completed measures of COVID-19 information-seeking skills, knowledge, prevention intentions, and prevention behaviors.Results: A series of hierarchical multiple regressions with data-driven covariates showed that neurocognition (viz, episodic verbal memory and executive functions) was independently related to COVID-19 knowledge (e.g. symptoms, risks) at a medium effect size, but not to information-seeking skills, prevention intentions, or prevention behaviors. Health literacy was independently related to all measured aspects of COVID-19 health information and did not interact with neurocognition in any COVID-19 health domain.Conclusions: Individual differences in neurocognition and health literacy played independent and meaningful roles in the initial acquisition of knowledge related to COVID-19, which is a novel human health condition. Future studies might examine whether neurocognitive supports (e.g. spaced retrieval practice, elaboration) can improve COVID-19-related knowledge and health behaviors in vulnerable populations.

Abstract
Apathy is common in HIV, separable from depression, and has been associated with non-adherence to antiretroviral therapy (ART). We examined the associations between apathy and critical psychological determinants of ART adherence, as per the information-motivation-behavioral model, in 85 persons living with HIV. Apathy was measured using a composite of the apathy subscale of the Frontal Systems Behavioral Scale and the vigor-activation scale of the Profile of Mood States. Independent of major depressive disorder, apathy was related at small-to-medium effect sizes with motivation to adhere and self-efficacy for health-related decision-making and medication management, but not with HIV knowledge or medication management skills. These findings suggest that apathy plays a unique role in several critical health adherence determinants and support the importance of assessment and management of apathy to maximize health outcomes among individuals with HIV disease.

Abstract
Abstract
Objective
Spaced retrieval practice (SRP) and self-generation are among the most replicated and effective mnemonic strategies in the cognitive psychology literature, but their benefits have not yet been realized in healthcare settings. This study used a randomized, between-subjects design to examine the hypothesis that SRP with a self-generation booster can improve memory for health-related information among clinically referred persons with HIV (PWH), who often have difficulty acquiring new health knowledge.
Method
A consecutive series of 41 PWH referred to a county-funded urban neuropsychology clinic were enrolled. Participants were randomly assigned to learn four statements about the treatment of a mock infectious disease in either a massed study control condition (n = 20) or an SRP condition (n = 21) in which they received two distributed free recall training tests supplemented with self-generation for missed items. The primary outcome was participants’ free recall of the four treatment statements after a 20-minute delay filled with nonverbal tests.
Results
PWH participants in the SRP condition were four times more likely than controls to recall at least one treatment statement at the 20-minute delay. SRP was not related to post-test recognition or health-related decision-making performance but was associated with moderately better self-efficacy for decision-making.
Conclusions
Findings from this pilot study show the potential of SRP with a self-generation booster to improve learning and memory for health-related information among PWH in clinic.

Abstract
Introduction: Growing access to both legitimate and dubious sources of health information makes accurate source memory increasingly important, yet it may be negatively impacted by conditions that impair prefrontal functioning, including HIV. This study hypothesized that instructions supporting source encoding on a health-related memory task would disproportionately benefit source memory of people with HIV (PWH), and to examine the pattern of source memory errors that are observed.Method: 102 individuals (61 HIV+, 41 HIV-) completed comprehensive neurobehavioral (including health literacy) and neuromedical evaluations, and were randomly assigned to one of two conditions for a health-related memory task: Attend to Source Instructions explicitly participants to attend to the source of health statements presented to them, which were either health professionals or lay-persons, whereas no such instruction was provided in a Control Instructions condition.Results: There was no significant interaction of HIV status by condition or main effect of HIV (ps>.05). There was a main effect of condition whereby those who received Attend to Source Instructions performed better on item-corrected source memory than those in the Control Instructions condition (p =.04). Those who received Control Instructions were more likely to misattribute the source of the health information to a health professional when the correct source was a lay-person (Cohen's d = -0.53), which was correlated with poorer overall cognitive performance (p =.008) and performance-based measures of health literacy (ps<.05).Conclusions: Given that people are rarely reminded to attend to the source of new health information in the real world, the risk for misattributing health information to a qualified health professional in the absence of such instructions raises the concern that people may readily incorporate questionable health recommendations into their health regimen, particularly among persons with poorer cognitive functioning and lower levels of health literacy. This may have significant downstream health consequences such as drug interactions, side effects, and inefficacy.

Abstract
OBJECTIVE People living with HIV (PLWH) are at higher risk for poorer neurocognitive functioning and health literacy than uninfected persons, which are associated with worse medical outcomes. Aging research suggests that the effect of neurocognitive functioning on health outcomes may be more pronounced in those with low health literacy. We aimed to determine whether low health literacy might amplify the adverse effects of neurocognitive functioning on treatment management outcomes in 171 PLWH aged 40+. METHOD In this cross-sectional, observational study, participants completed a well-validated battery of neurocognitive, health literacy, and treatment management measures. A binary health literacy variable (low vs. adequate) was determined via established cut points on the well-validated health literacy tests. Treatment management outcomes included biomarkers of HIV (i.e., CD4 counts and viral load), self-management of HIV disease (i.e., self-reported medication adherence and self-efficacy for HIV disease management), and performance-based health-related decision-making. RESULTS Forty-seven percent of the sample met the criteria for low health literacy. Multivariable regressions adjusting for clinicodemographic (e.g., race, socioeconomic status) covariates revealed significant interactions for self-efficacy for HIV disease management and health-related decision-making, such that neurocognitive functioning was associated with these outcomes among those with low, but not adequate health literacy. CONCLUSIONS Findings suggest that low health literacy may increase the vulnerability of PLWH to the adverse effects of neurocognitive impairment on health outcomes, or conversely that adequate health literacy may provide a buffer against the health risks associated neurocognitive impairment. Interventions targeting health literacy in PLWH may mitigate the effects of neurocognitive impairment on health outcomes.

Abstract
OBJECTIVE Determine the latent structure of health literacy in persons living with HIV (PLWH) and its association with health management and decision-making. Method: Participants included 220 PLWH and 123 seronegative participants from Southern California and Alabama who completed a battery of well-validated health literacy measures, along with assessments of health management self-efficacy, health-related decision-making, depression, and basic clinical laboratory measures. Results: Exploratory factor analysis in HIV - participants showed that the shared variance between a battery of health literacy measures, including health word reading, verbal comprehension, numeracy, and self-reported problems was best explained by a single factor. Similarly, a confirmatory factor analysis in PLWH also supported a single factor structure, but for a re-specified four-test solution based on the core performance-based measures of health literacy. In analyses adjusting for demographics, PLWH demonstrated significantly lower health literacy composite scores as compared to their HIV - counterparts. Among PLWH, lower health literacy was independently associated with lower self-efficacy for health management and poorer health-related decision-making. Conclusions: Findings suggest that numeracy, word recognition, and verbal comprehension and reasoning comprise a unitary construct of health literacy that is lower in PLWH as compared to seronegatives and is independently associated with important downstream aspects of health management and decision-making.

Abstract
Low health literacy is associated with challenges for those living with HIV including medication non-adherence and poorer health outcomes. The aim of this study was to systematically review the literature on health literacy and health outcomes in persons living with HIV. The extended guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, as well as A Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist were utilized to guide the approach to the review. A variety of electronic databases including PubMed, CINAHL, PsychInfo, and Cochrane Library were searched. Additional literature available on U.S. government websites was also included in the search. Search terms were used in a variety of combinations and included HIV, health literacy, adherence, and health outcomes. Forty-eight studies were identified that addressed health literacy and health outcomes in HIV. Although several studies in this review did not provide robust results of statistical significance linking health literacy with health outcomes, all of the studies addressed the key significance of health literacy within the scope of living with HIV disease. The relationship between health literacy and the identified health outcomes requires further research and explication.

Abstract
Engagement in care is a key component of the HIV treatment cascade and is influenced by biopsychosocial factors. Little is known about the association of health literacy with this impactful outcome in people living with HIV (PLWH). Ninety-five PLWH completed a comprehensive battery including health literacy measures covering several domains (i.e., numeracy, reading, self-efficacy, and ability to appraise and access health information). Engagement in care was operationalized as missed clinic visits (i.e., proportion of clinic visits in the prior 24 months where the participant did not attend and did not cancel or reschedule). The ability to appraise health information (measured by the Newest Vital Sign [NVS]) was the only significant health literacy predictor of missed clinic visits. Hierarchical linear regression including clinico-demographics and all health literacy variables showed that age, depression, neurocognition, and NVS were significant (p < 0.05) correlates of missed clinic visits. The ability to appraise health information was a strong and independent predictor of missed clinic visits in PLWH, even in the context of traditional correlates. Such measures may be useful in identifying PLWH with low health literacy who may be at risk for poorer engagement in care. Future research developing interventions targeting this health literacy dimension are warranted.

Abstract
HIV-associated neurocognitive impairment is an independent predictor of low general health literacy, which can be associated with poor disease outcomes (e.g., viremia). Given the increasing frequency with which health behaviors occur in an online environment (e.g., health information seeking, provider interactions), there is a specific need to understand the predictors of electronic health (eHealth) literacy of persons living with HIV disease. In this study, 90 HIV+ persons completed the eHealth Literacy Scale (eHEALS), which measures one's awareness, skills and evaluation of online health resources. Participants also completed a comprehensive battery of clinical neurocognitive tests and well-validated performance-based measures of general health literacy capacity (e.g., knowledge, numeracy). Results showed that, independent of education, lower neurocognitive function was moderately related to lower eHEALS scores, particularly in the domains of learning and motor skills. Of particular note, general health literacy capacity emerged as a significant mediator of the relationship between neurocognition and eHealth literacy. Thus, the adverse effects of neurocognition on health literacy capacity carries a downstream adverse influence on HIV+ persons' awareness, skills, and evaluation of health-related resources in the online environment.

Abstract
HIV enters the central nervous system (CNS) early after infection. HIV-associated neurocognitive disorders (HAND) remain a serious complication of HIV infection despite available antiretroviral therapy (ART). Neurocognitive deficits observed in HAND are heterogeneous, suggesting a variability in individuals' susceptibility or resiliency to the detrimental CNS effects of HIV infection. This chapter reviews primary host genomic changes (immune-related genes, genes implicated in cognitive changes in primary neurodegenerative diseases), epigenetic mechanisms, and genetic interactions with ART implicated in HIV progression or HAND/neurocognitive complications of HIV. Limitations of the current findings include diversity of the HAND phenotype and limited replication of findings across cohorts. Strategies to improve the precision of future (epi)genetic studies of neurocognitive consequences of HIV infection are offered.

Abstract
Obtaining informed consent is a great challenge in global health research. There is a need for tools that can screen for and improve potential research participants' understanding of the research study at the time of recruitment. Limited empirical research has been conducted in low and middle income countries, evaluating informed consent processes in genomics research. We sought to investigate the quality of informed consent obtained in a South African psychiatric genomics study. A Xhosa language version of the University of California, San Diego Brief Assessment of Capacity to Consent Questionnaire (UBACC) was used to screen for capacity to consent and improve understanding through iterative learning in a sample of 528 Xhosa people with schizophrenia and 528 controls. We address two questions: firstly, whether research participants' understanding of the research study improved through iterative learning; and secondly, what were predictors for better understanding of the research study at the initial screening? During screening 290 (55%) cases and 172 (33%) controls scored below the 14.5 cut-off for acceptable understanding of the research study elements, however after iterative learning only 38 (7%) cases and 13 (2.5%) controls continued to score below this cut-off. Significant variables associated with increased understanding of the consent included the psychiatric nurse recruiter conducting the consent screening, higher participant level of education, and being a control. The UBACC proved an effective tool to improve understanding of research study elements during consent, for both cases and controls. The tool holds utility for complex studies such as those involving genomics, where iterative learning can be used to make significant improvements in understanding of research study elements. The UBACC may be particularly important in groups with severe mental illness and lower education levels. Study recruiters play a significant role in managing the quality of the informed consent process.

Household Everyday Functioning in the Internet Age: Online Shopping and Banking Skills Are Affected in HIV-Associated Neurocognitive Disorders. J Int Neuropsychol Soc 2017; 23. [PMID: 28625210 PMCID: PMC5703204 DOI: 10.1017/s1355617717000431] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/06/2022]
Abstract
OBJECTIVES The Internet is a fundamental tool for completing many different instrumental activities of daily living (IADL), including shopping and banking. Persons with HIV-associated Neurocognitive Disorders (HAND) are at heightened risk for IADL problems, but the extent to which HAND interferes with the performance of Internet-based household IADLs is not known. METHODS Ninety-three individuals with HIV disease, 43 of whom were diagnosed with HAND, and 42 HIV- comparison participants completed Internet-based tests of shopping and banking. Participants used mock credentials to log in to an experimenter-controlled Web site and independently performed a series of typical online shopping (e.g., purchasing household goods) and banking (e.g., transferring funds between accounts) tasks. RESULTS Individuals with HAND were significantly more likely to fail the online shopping task than neurocognitively normal HIV+ and HIV- participants. HAND was also associated with poorer overall performance versus HIV+ normals on the online banking task. In the HAND group, Internet-based task scores were correlated with episodic memory, executive functions, motor skills, and numeracy. In the HIV+ sample as a whole, lower Internet-based task scores were uniquely associated with poorer performance-based functional capacity and self-reported declines in shopping and financial management in daily life, but not with global manifest functional status. CONCLUSIONS Findings indicate that HAND is associated with difficulties in using the Internet to complete important household everyday functioning tasks. The development and validation of effective Internet training and compensatory strategies may help to improve the household management of persons with HAND. (JINS, 2017, 23, 605-615).

[PMID: 27551024 DOI: 10.1093/arclin/acw051] [Citation(s) in RCA: 56] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/22/2016] [Indexed: 11/13/2022] Open
Abstract
It is often necessary for neuropsychologists, clinical psychologists, and other healthcare professionals to assess an individual's capacity to consent to treatment related to healthcare. This task can be challenging and requires a delicate balance of both respect for individuals' autonomy, as well as the protection of individuals with diminished capacity to make an autonomous decision. The purpose of the present review is to provide an overview of the conceptual model of decisional capacity as well as a brief summary of some of the currently available instruments designed to help evaluate medical decision making. In addition, current empirical literature on the relationship between neuropsychological abilities and decision-making capacity is discussed and a brief set of recommendations is provided to further aid clinicians or consultants when they are required to complete the ethically important but difficult task of making determinations about healthcare decision-making capacity.
