[PMID: 36618901 PMCID: PMC9813694 DOI: 10.1016/j.eclinm.2022.101792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 11/28/2022] [Accepted: 11/30/2022] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND High antiretroviral therapy (ART) coverage and viral suppression among people with HIV (PWH) in Australia provide a unique context to study individual cognitive trajectories, cognitive aging and factors associated with longitudinal cognitive function during chronic and stable HIV disease. METHODS Participants from the Predictors of Adherence to Antiretroviral Therapy study (n = 457, recruited between September 2013 and November 2015, median age = 52 years, and all with HIV RNA <50 copies mL) completed a cognitive assessment with CogState Computerized Battery (CCB) at baseline, Month-12, and Month-24. Demographics, psycho-social and socioeconomic factors, healthcare seeking behaviors, HIV disease characteristics and comorbidities were assessed. The CCB data were corrected for age, sex and practice effect and averaged into a global z-score (GZS). Cognitive impairment was defined with the global deficit score method (GDS>0.5). Meaningful cognitive change was statistically defined (decline or improvement versus stability, i.e., 90% CI, that is p < 0.05, 2-tailed) using a novel evidence-based change score: the linear mixed-effect regression (LMER)-based GZS change score. A separate LMER model with a top-down variable selection approach identified the independent effects of age and other demographic, HIV disease characteristics, socioeconomic and health-related factors on the demographically corrected GZS. The combined definitions of change and cross-sectional impairment enabled the identification of cognitive trajectories. FINDINGS At Month-12 and Month-24, 6% and 7% showed meaningful cognitive decline and 4% and 3% improved respectively. Only 1% showed sustained decline. Incident impairment due to subtle cognitive decline (i.e., below the threshold of meaningful cognitive decline) was 31% and 25% at Month-12 and Month-24, while 14% showed sustained impairment (i.e., cognitively impaired at all study visits). Older age (≥50 years) and time interaction was associated with lower demographically corrected GZS (β = -0.31, p < 0.001). Having a regular relationship, excellent English proficiency, and perceived stigma (avoidance) were associated with higher GZS (all p < 0.05). Relying on government subsidy, severe depression, and lower belief in ART necessity and higher concerns were associated with lower GZS (all p < 0.05). No HIV disease characteristics had a significant effect. INTERPRETATIONS Meaningful cognitive decline was not different from normal expectation in chronic stable HIV disease. Despite this, subtle cognitive decline, sustained cognitive impairment, and greater than normative-age cognitive aging were evident. FUNDING Funding for the PAART study was provided in part by unrestricted educational grants from Gilead Sciences (www.gilead.com) (Grant Number: IN-AU-264- 0131), the Balnaves Foundation (www.balnavesfoundation.com), the Victorian Department of Health and Human Services (Australia) (www.dhs.vic.gov.au/home), Western Australia Health (www.health.wa.gov.au), the ACT Ministry of Health (Australia) (www.health.act.gov.au), and in-kind support from the Queensland Department of Health (Australia) (www.health.qld.gov.au), and NHMRC Partnership grant APP1058474 (PI: Carr, Andrew).

Abstract
In Myanmar, an Asian country with one of the highest HIV-1 prevalence rates, counseling prior to initiating antiretroviral therapy (ART) is standard care, either by a healthcare worker (standard counselor, SC) or trained counselor who is also living with HIV (peer counselor, PC). PC is commonly utilized in Myanmar and other resource-limited settings. However, its benefit over SC is unclear. We conducted a cross-sectional survey of people living with HIV (PLWH), who completed either only PC or only SC before treatment initiation across four cities in Myanmar. Participants were evaluated for HIV knowledge, stigma, antiretroviral adherence, barriers to care, social support satisfaction and attitudes regarding both counseling processes. Bivariate analyses and multivariable mixed effects modeling were conducted to compare differences in these measures among PC and SC participants. Among 1006 participants (49% PC; 51% SC), 52% were females and median age was 37 years in those receiving PC and 40 years in those receiving SC. More than 70% of participants in both groups achieved up to grade school education. The average duration since HIV diagnosis was 4.6 years for PC and 5.7 years for SC participants. HIV knowledge and attitudes regarding counseling were good in both groups and more PC participants credited their HIV counselor for knowledge (75% vs 63%, p < 0.001). Compared to SC, PC participants had lower enacted stigma (Incidence Rate Ratio (IRR) 0.75, Confidence Interval (CI) [0.65, 0.86]), mean internalized stigma (-0.24, CI [-0.34, -0.14]), and risk of antiretroviral therapy non-adherence (Odds Ratio 0.59, CI [0.40, 0.88]), while reporting higher levels of barriers to care (9.63, CI [8.20, 11.75]). Our findings demonstrate potential benefits of PC compared to SC, and support the utilization of PC to enhance HIV health outcomes within the unique societal and geographical context of Myanmar, and possibly beyond.

Abstract
INTRODUCTION Understanding social and structural barriers that determine antiretroviral therapy (ART) adherence can improve care. Assessment of such factors is limited in Myanmar, a country with high HIV prevalence and increasing number of people living with HIV initiating ART. METHODS Questionnaires were administered to adults with HIV across 4 Myanmar cities to estimate adherence and its potential determinants, including HIV knowledge, social support, barriers to care, enacted and internalized stigma, and engagement in peer-to-peer HIV counseling (PC). Associations were determined using logistic mixed-effects modeling. RESULTS Among 956 participants, the mean age was 39 years, 52% were female, 36% had CD4 <350 cells/mm3, and 50% received pre-ART PC. Good adherence was reported by 74% of participants who had better HIV knowledge than those reporting nonadherence. Among nonadherent, 44% were forgetful and 81% were careless about taking ART. Among all participants, most (53%) were very satisfied with their social support and 79% reported lack of financial resources as barriers to care. Participants most frequently reported being viewed differently by others (30%) and feeling as if they were paying for past karma or sins because of their HIV diagnosis (66%). Enacted stigma (odds ratio 0.86; 95% confidence interval 0.79 to 0.92, P < 0.01) and internalized stigma (odds ratio 0.73; 95% confidence interval: 0.56 to 0.95, P = 0.023) were associated with worse adherence. CONCLUSIONS Increased self-reported ART adherence in Myanmar is associated with less enacted and internalized stigma. These findings suggest the benefit of developing and promoting adherence interventions, which are focused on mitigating HIV-related stigma in the county.

HIV infection is linked with reduced error-related default mode network suppression and poorer medication management abilities. Prog Neuropsychopharmacol Biol Psychiatry 2021; 111:110398. [PMID: 34224796 PMCID: PMC8380727 DOI: 10.1016/j.pnpbp.2021.110398] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 06/07/2021] [Accepted: 06/29/2021] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Brain activity linked with error processing has rarely been examined among persons living with HIV (PLWH) despite importance for monitoring and modifying behaviors that could lead to adverse health outcomes (e.g., medication non-adherence, drug use, risky sexual practices). Given that cannabis (CB) use is prevalent among PLWH and impacts error processing, we assessed the influence of HIV serostatus and chronic CB use on error-related brain activity while also considering associated implications for everyday functioning and clinically-relevant disease management behaviors. METHODS A sample of 109 participants, stratified into four groups by HIV and CB (HIV+/CB+, n = 32; HIV+/CB-, n = 27; HIV-/CB+, n = 28; HIV-/CB-, n = 22), underwent fMRI scanning while completing a modified Go/NoGo paradigm called the Error Awareness Task (EAT). Participants also completed a battery of well-validated instruments including a subjective report of everyday cognitive failures and an objective measure of medication management abilities. RESULTS Across all participants, we observed expected error-related anterior insula (aI) activation which correlated with better task performance (i.e., less errors) and, among HIV- participants, fewer self-reported cognitive failures. Regarding awareness, greater insula activation as well as greater posterior cingulate cortex (PCC) deactivation were notably linked with aware (vs. unaware) errors. Regarding group effects, unlike HIV- participants, PLWH displayed a lack of error-related deactivation in two default mode network (DMN) regions (i.e., PCC, medial prefrontal cortex [mPFC]). No CB main or interaction effects were detected. Across all participants, reduced error-related PCC deactivation correlated with reduced medication management abilities and PCC deactivation mediated the effect of HIV on such abilities. More lifetime CB use was linked with reduced error-related mPFC deactivation among HIV- participants and poorer medication management across CB users. CONCLUSIONS These results demonstrate that insufficient error-related DMN suppression linked with HIV infection, as well as chronic CB use among HIV- participants, has real-world consequences for medication management behaviors. We speculate that insufficient DMN suppression may reflect an inability to disengage task irrelevant mental operations, ultimately hindering error monitoring and behavior modification.

Abstract
BACKGROUND The psychological characteristics of ego functions interfere with self-care behavior in several diseases. However, the effect of ego functions on self-care behavior after education in heart failure (HF) remains unclear. METHODS Seventy-one HF patients were enrolled. Patients' scores on the Japanese version of the European Heart Failure Self-care Behaviour Scale (EHFScBS) were measured before and after the HF intervention, and the rate of change was used as an indicator of educational effectiveness. The Tokyo University Egogram New Ver. II was used to assess five types of ego state functions: Critical parent, Nurturing parent, Adult, Free Child, and Adapted Child (AC). RESULTS A comparison of the five ego states showed that AC scores were significantly lower than those of the other ego states (p < 0.01). Total EHFScBS scores significantly decreased from 33 (26-39) to 16 (14-20) (p < 0.01) after the HF education, and the median rates of change in EHFScBS was -46.2%. Patients with a lower rate of change in EHFScBS were more likely to have low AC scores, as characterized by a lack of compliance and coordination, and were less likely to receive higher education (all p < 0.05). Even after adjustment for covariates, low AC scores were independently associated with low rate of change in EHFScBS (p < 0.01). CONCLUSIONS Educational behavior change for self-care is less effective in HF patients with an ego state with low AC.

Abstract
HIV-related stigma and beliefs about medication necessity and concerns have separately demonstrated significant associations with antiretroviral adherence in people with HIV. However, no work has examined both of these associations in the same model. Based on the necessity-concerns framework, this study examined four alternative models of relationships among HIV-related stigma, medication beliefs, and adherence. Cross-sectional analyses were used to test the four alternative models to best depict associations among HIV-related stigma, medication beliefs, and medication adherence. Models tested included two indirect effects models, an interaction model, and a simple predictors model with no interaction or indirect effects. The outcome variable was HIV medication adherence, and model fit was determined by variance accounted for, Akaike information criterion (AIC), and Bayesian information criterion (BIC) values. An interaction model between internalized stigma and medication concerns accounted for the most variance in adherence. There was also a significant indirect effect of internalized stigma on adherence via medication concerns. Medication concerns are a promising target for interventions focusing on increasing adherence among people with HIV.

Development of the InCharge Health Mobile App to Improve Adherence to Hydroxyurea in Patients With Sickle Cell Disease: User-Centered Design Approach. JMIR Mhealth Uhealth 2020; 8:e14884. [PMID: 32383683 PMCID: PMC7245000 DOI: 10.2196/14884] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 10/31/2019] [Accepted: 01/26/2020] [Indexed: 12/31/2022] Open
Abstract
Background Sickle cell disease (SCD) is an inherited blood disorder causing acute complications and chronic progressive end organ damage. SCD is associated with significant morbidity, early mortality, impaired health-related quality of life, and increased acute health care utilization. Hydroxyurea is a US Food and Drug Administration–approved medication that reduces disease complications, acute health care utilization, and costs. However, adherence to hydroxyurea is suboptimal. Mobile health (mHealth) interventions have the potential to improve hydroxyurea adherence, but few examples exist that are specific to the SCD population. Objective This study aimed to design a mHealth intervention for individuals with SCD to improve adherence to hydroxyurea, using a user-centered design that was informed by specific barriers to hydroxyurea adherence and utilization in this population. Methods This study consisted of 4 phases. In phase 1, individuals with SCD and health care providers participated in an optimization digital workshop. In phase 2, patients completed surveys pertaining to their interest in mHealth use, barriers and facilitators to hydroxyurea use, and health literacy. Phases 3 and 4 involved semistructured interviews and focus groups, respectively, and used the Health Belief Model (HBM) as the framework to investigate drivers of poor hydroxyurea adherence and to inform the development of an app prototype. In addition, in phase 4, we have incorporated the patients’ feedback on the preliminary app prototype and its features. Results Barriers to hydroxyurea adherence were consistent with the literature and included forgetfulness and several specific thoughts and emotions associated with hydroxyurea use (eg, fear of side effects, depression, stigma, and hopelessness). In addition, more than half of the participants reported potentially low health literacy. Preferred patient app features included 7 key components, namely (1) medication reminders and tracker, (2) disease education, (3) communication, (4) personalization, (5) motivation, (6) support during pain episodes, and (7) social support. Utilizing a user-centered design approach, data obtained from patients and providers were translated into features within the app, mapping to components of the HBM and the specific drivers of hydroxyurea adherence and matching the literacy level of the population, resulting in the development of a novel mobile app called InCharge Health. Conclusions The InCharge Health app is an mHealth intervention developed with substantial input from users and by mapping the HBM as the framework that guided the choice for its components. InCharge Health is a customized product for the SCD population aimed at optimizing medication adherence, with the end goal of improving quality of life and health outcomes among patients with SCD. The efficacy and implementation of the InCharge Health app as an mHealth intervention to promote hydroxyurea adherence will be tested in a future stepped-wedge multicenter trial for adolescents and adults with SCD.

Abstract
OBJECTIVES To assess whether medication beliefs differ between women who use or not use medication for their somatic chronic diseases during pregnancy and whether this association varies across diseases. DESIGN Cross-sectional web-based survey. SETTING Multinational study in Europe. PARTICIPANTS Pregnant women or women with children less than 1 year old from European countries and with asthma, allergy, cardiovascular, rheumatic diseases, diabetes, epilepsy and/or inflammatory bowel diseases (IBD). PRIMARY AND SECONDARY OUTCOME MEASURE Differences in scores of the Beliefs about Medicines Questionnaire (BMQ). RESULTS In total, 1219 women were included (ranging from 736 for allergy to 49 for IBD). Women using medication for their chronic disease (n=770; 63%) had higher scores on the BMQ subscales necessity (16.6 vs 12.1, p<0.001) and benefits (16.2 vs 15.4, p<0.001), and lower values on the subscales overuse (12.5 vs 13.1; p=0.005) and harm (9.8 vs 10.7, p<0.001) than women not using medication. No significant differences were shown for the concerns subscale (12.5 vs 12.3, p=0.484). Beliefs varied somewhat across diseases but in general more positive beliefs among women using medication were shown. Epilepsy was the disease where less differences were observed between women using and not using medication. CONCLUSION Women's beliefs were associated with medication use during pregnancy with only small differences across the diseases. Knowing pregnant women's beliefs could help identify women who are reluctant to use medication and could guide counselling to support making well-informed treatment decisions.

Abstract
Background Adherence in the context of patients with acute conditions is a major public health issue. It is neglected by the research community and no clinically validated generic scale exists to measure it. Objective To construct and validate a Global Adherence Scale usable in the context of Acute Conditions (GASAC) that takes into account adherence both to advice and to all types of prescriptions that the doctor may give. To measure adherence and to study its determinants. Materials and method We based the construction of the GASAC questionnaire on a theoretical model and a literature search. Then, between 2013 and 2014, we validated it in a prospective observational study in two hospital emergency departments. Patients were contacted by phone about one week after their consultation to answer several questionnaires, including GASAC and the Girerd self-administered questionnaire about medication adherence as a control. Results GASAC consists of four adherence subscales: drug prescriptions; blood tests/ radiography prescriptions; lifestyle advice and follow-up instructions. An analysis of the 154 sets of answers from patients showed that the GASAC drug subscale had satisfactory internal coherence (Cronbach’s alpha = 0.78) and was correlated with the Girerd score, as was GASAC as a whole (p<0.01). The median score was 0.93 IQR [0.78–1] for a maximum value of 1 (n = 154). In multivariaable analysis, infection was more conducive of good adherence (cut off at ≥ 0.8; n = 115/154; 74.7% [67.0–81.3]) than trauma (OR 3.69; CI [1.60–8.52]). The Doctor-Patient Communication score (OR 1.06 by score point, CI [1.02–1.10]) also influenced adherence. Conclusions GASAC is a generic score to measure all dimensions of patient adherence following emergency departments visits, for use in clinical research and the evaluation of clinical practice. The level of adherence was high for acute conditions and Doctor-Patient Communication was a major determinant of adherence.

Abstract
According to the Necessity-Concerns Framework, beliefs about medication necessity and concerns are two core themes from diverse patient medication beliefs across chronic illnesses that may directly influence adherence. Past work has supported associations of necessity and concerns to adherence in the chronic disease literature and in HIV research. However, there has not been a focused review of the literature on associations of necessity and concerns to HIV medication adherence, nor on what variables may influence these associations. This systematic review synthesized findings from 26 studies regarding associations of necessity and concerns to HIV medication adherence. Both beliefs showed small, clinically significant effects on adherence. A subset of studies identified perceptions of healthcare providers as determinants of necessity and concerns beliefs with indirect effects on adherence. Overall, necessity and concerns demonstrated clinically significant associations to adherence among people with HIV.

Abstract
The researcher assessed the beliefs and adherence associated with both oral deferasirox and deferoxamine infusion chelation therapies among Jordanian children with thalassemia major, and compared the adherence levels between the recipients of each. In this descriptive cross-sectional study, 120 participants were recruited from 3 major thalassemia treatment clinics in Jordan using convenience sampling. Data were collected through questionnaires on demographic- and disease-related information, the beliefs about medicines, and a medication adherence report scale. Most participants showed a high adherence to deferoxamine infusion and oral deferasirox (87.20% and 89.08%, respectively), and believed in the necessity of deferoxamine for maintaining health (89.34%). However, 41.32% of the participants had strong concerns about deferoxamine use. While most participants believed in the need for oral deferasirox (89.84%), about 40.7% had strong concerns about its use. An independent samples t test showed no statistically significant difference in the adherence between the oral deferasirox and infusion deferoxamine recipients (t=1.048, DF=118, P=0.075). Jordanian children with thalassemia have positive beliefs and adherence to both oral and infusion chelation therapies. Health care providers should pay attention to patients' beliefs and discuss the major concerns pertaining to iron chelation therapy with them to enhance the continuity of adherence therapy.

Abstract
Background: Little is known about transgender women's beliefs and experiences of hormone therapy (HT), as part of their transition process, and particularly as they grow older. Aims: This study aimed to investigate: (i) transgender women's experiences and attitudes to HT, and (ii) expectations of what might occur and/or what occurred after they reached "menopausal age." Methods: Participants were recruited through invitations to an online survey sent to 138 Lesbian, gay, bisexual, transgender plus (LGBT+) support groups across the UK. Sixty-seven transgender women consented and completed the questionnaire; responses were analyzed using a mixed-methods approach. The beliefs about medicines questionnaire (BMQ) was used to assess beliefs about HT, while an inductive thematic qualitative approach was used to explore participants' personal expectations and experiences of HT and their views about the menopause. Results: Participants were aged on average 49 years ranging from 20 to 79 years old. Most (96%) were taking HT. BMQ scores revealed strong beliefs about the necessity of HT and some concerns. Positive views about HT were expressed, with themes including treatment importance, personal and mental health benefits, but concerns about long-term effects, side effects, and maintaining access to the treatment were also mentioned. Views about menopause included uncertainty and questioning of its relevance; some mentioned changes to HT dosage, but most expected to use HT indefinitely. Discussion: This study provides exploratory qualitative and quantitative information about transgender women's views about HT and menopause. Practical implications include improving access to HT and provision of evidence-based information about long-term use.

Abstract
Background Adherence in chronic disease conditions is described as the extent to which a person‘s behaviour corresponds to the prescribed medical advice of the healthcare provider. This is not limited to medication intake only but also includes acts such as following instructions regarding dietary or fluid restrictions and taking medicines at the prescribed times and intervals. Although adherence to antiretroviral therapy (ART) is a predictor of good clinical outcome among HIV-infected persons on ART, it is a major challenge and strict adherence is not very common. This article aims to examine the application and relevance of some cognitive-behavioural theories in antiretroviral therapy adherence Methods After doing a thorough literature review, contemporary theories of health behaviour at the individual and interpersonal levels referred to as cognitive-behavioural theories were explored. This review highlights some aspects of the cognitive perspective of health behaviour theories as a good theoretical framework that could be used for organising thoughts about adherence and other health behaviours among patients on lifelong treatment such as ART. Results Key concepts of these theories stipulate that behaviour is mediated by cognition i.e. knowledge and attitude affect the person’s action. In addition, cognitive-behavioural theories recognise knowledge alone as being insufficient to produce behavioural change; a person’s perception, motivation, skills and social environment are all influential in the process of behavioural change. Conclusion Prediction of medication adherence is complex, and health-related knowledge and beliefs alone are insufficient to achieve behaviour change, especially in chronic conditions such as HIV/AIDS. However, people can control or influence the events affecting their lives by integrating cognitive, social, and behavioural sub-skills related to beliefs of personal efficacy in performing these skills.

Abstract
BACKGROUND There is no validated generic tool to measure Doctor-Patient-Communication (DPC) in a context of acute conditions. OBJECTIVE To create and validate such a scale in a real population. MATERIALS AND METHOD We performed a systematic review of validated DPC scales available in English. From these, using a theoretical model based on a multidisciplinary approach, we selected pertinent items that met the inclusion criteria and included them in a simple questionnaire. This tool based on a synthesis of the literature was then validated in a prospective study in two hospital emergency departments. RESULTS We found 22 pertinent questionnaires and scoring systems. From these, we extracted items and built a scale based on 15 questions with graded responses (Likert from 1 to 4). The mean time for questionnaire completion was 3 minutes. We included 189 adults and adolescents in the study and analyzed complete responses to the questionnaire by 149 patients, gathered over the phone one week after their consultation. The scale had high internal consistency (Cronbach's alpha = 0.89) and good external validity. Two questions were removed due to redundancy giving a scale based on 13 questions. CONCLUSIONS We have created an easy-to-use and validated generic questionnaire to assess DPC in a context of acute conditions, usable both in clinical research and in routine practice.

Abstract
BACKGROUND Hydroxyurea reduces complications and improves health-related quality of life (HRQOL) in sickle cell disease (SCD) patients, however adherence remains suboptimal. Understanding patients' views of hydroxyurea is critical to optimize adherence, particularly in adolescents and young adults (AYA). Study objectives were to assess beliefs about hydroxyurea using the Beliefs about Medicines Questionnaire (BMQ), and to examine the relationship of patients' beliefs to their hydroxyurea adherence and HRQOL. METHODS Thirty-four AYA with SCD participated in a cross-sectional study January-December 2015. Study assessments included BMQ to examine beliefs about hydroxyurea; Visual Analogue Scale (VAS) to assess hydroxyurea adherence; and Patient Reported Outcomes Measurement Information System (PROMIS®) to evaluate HRQOL. RESULTS Participants (41% female, 91% Black) had median age of 13.5 (IQR 12-18) years. Participants' concerns about overuse of medications correlated with concerns about hydroxyurea (rs = 0.36, p = 0.04) and overall harm of medications (rs = 0.5, p = 0.003). Participants' age positively correlated with the necessity of hydroxyurea (rs = 0.45, p = 0.007). Participants' concerns about hydroxyurea and overuse of medications positively correlated with anxiety (rs = 0.41, p = 0.02; rs = 0.44, p = 0.01) and depression (rs = 0.37, p = 0.04; rs = 0.54, p = 0.001), but inversely correlated with peer relationships (rs = -0.45, p = 0.03; rs = -0.44, p = 0.03), respectively, suggesting better HRQOL with concerns. Fifty percent of participants reported low hydroxyurea adherence (VAS < 80%), which was more seen in patients with higher concerns about hydroxyurea (p = 0.02). CONCLUSIONS Beliefs about hydroxyurea correlated with HRQOL scores and adherence levels. Addressing patients' concern about hydroxyurea and medications overall as well as routine assessment of adherence and beliefs could help to overcome adherence barriers.

Abstract
Background Inappropriate use of non-prescription remedies by persons living with human immunodeficiency virus (PLHIV) may result in adverse events or potentiate non-adherence to prescribed medications. This study investigated the use of non-prescription remedies among PLHIV receiving antiretroviral therapy (ART) from four treatment centers in southern Ghana. Methods A mixed method design using quantitative and qualitative methods was used. This article focuses on the quantitative survey of 540 respondents. Univariate analysis was used to generate descriptive tabulations of key variables. Bivariate analysis and logistic regression modeling, respectively, produced unadjusted and adjusted associations between background attributes of PLHIV and the use of non-prescription remedies. A p-value of < 0.05 was considered statistically significant. All analyses were performed using IBM SPSS Statistics for Windows, Version 20.0. Results One out of three respondents reported the use of non-prescription remedies at least once within 3 months of the survey. Most of these were locally made and included “Angel natural bitters, concoctions from the Christian prayer centers, garlic, and mahogany syrups.” These remedies were used concomitantly with antiretroviral medications (ARVs)—46% or administered with ARVs but at different times during the day (43%). Some of the remedies were reportedly prescribed by health workers, or self-initiated during periods of ARVs shortage. Others took them based on their perception of their efficacy. Bivariate level analysis identified ART clinic site, place of residence, and ARV adherence monitoring to be significantly associated with the use of non-prescription remedies (p < 0.05). Multiple logistic regression analysis controlling for covariates confirmed the location of ART clinic as the only predictor of the use of non-prescription remedies. Compared to clients at the large urban teaching hospital (Korle-Bu Fevers Unit ART center), those at the district level (Atua ART center) were ninefold more likely to use non-prescription remedies [adjusted odds ratio (AOR) = 8.84; 95% confidence interval (CI) 2.83–33.72]. Those from a district level mission hospital (St. Martin’s ART center) were threefold as likely to use these remedies (AOR = 2.610; 95% CI 1.074–9.120). Conclusion The use of non-prescription remedies by PLHIV on ART is common in southern Ghana. Usage is mostly self-initiated because of perceived efficacy of remedy, and was more common among clients attending rural ART clinics.

Abstract
BACKGROUND Physician attitude influences the way patients cope with diagnosis and therapy in chronic severe diseases such as cancer. Previous studies showed that such an effect exists in HIV care; it is likely that it begins with the first contact with a physician. OBJECTIVE We aimed to explore in HIV-infected persons their perception of the first consultation they had with an HIV specialist (PFC-H), and whether this perception correlates with adherence to antiretroviral therapy. METHOD The study was conducted in Grenoble University Hospital, France, a tertiary care center. Every antiretroviral-experienced patient was asked to freely complete a self-reported, anonymous questionnaire concerning retrospective PFC-H, present adherence (Morisky scale), and present perceptions and beliefs about medicine (BMQ scale). RESULTS One hundred and fifty-one questionnaires were available for evaluation. PFC-H score and adherence were correlated, independently from age, gender, and numbers of pill(s) and of pill intake(s) per day. BMQ score also correlated with adherence; structural equation analysis suggested that the effect of PFC-H on adherence is mediated by positive beliefs. CONCLUSION These results suggest that for HIV-infected persons, the perceptions remaining from the first consultation with an HIV specialist physician influence important issues such as adherence and perception about medicine. Physicians must be aware of this potentially long-lasting effect.

Abstract
OBJECTIVE This meta-analysis investigated whether beliefs in the necessity and concerns of medicine and the necessity-concerns differential are correlated with medication adherence on a population level and in different conditions. METHODS An electronic search of Web of Science, EMBASE, PubMed and CINAHL was conducted for manuscripts utilising the Beliefs about Medicines Questionnaire and comparing it to any measure of medication adherence. Studies were pooled using the random-effects model to produce a mean overall effect size correlation. Studies were stratified for condition, adherence measure, power and study design. RESULTS Ninety-four papers were included in the meta-analysis. The overall effect size(r) for necessity, concerns, and necessity-concerns differential was 0.17, -0.18 and 0.24 respectively and these were all significant (p<0.0001). Effect size for necessity was stronger in asthma and weaker in the cardiovascular group compared to the overall effect size. CONCLUSION Necessity and concerns beliefs and the necessity-concerns differential were correlated with medication adherence on a population level and across the majority of included conditions. The effect sizes were mostly small with a magnitude comparable to other predictors of adherence. PRACTICE IMPLICATIONS This meta-analysis suggests that necessity and concern beliefs about medicines are one important factor to consider when understanding reasons for non-adherence.

Abstract
Aims Inadequate self‐care management is a leading cause of re‐hospitalization in patients with heart failure (HF). Psychological factors such as some ego functions interfere with self‐care behaviour modification, leading to poor outcomes in patients with several chronic diseases. However, characteristics of ego states in patients with repeated hospitalization for HF remain undefined. Methods and results The present study enrolled 40 HF outpatients with previous history of HF hospitalization and receiving self‐care management. Patients' psychological characteristics were assessed by Patient Health Questionnaire (PHQ‐9) for screening depressive symptoms, and the Tokyo University Egogram (TEG) New Version II for analysing human behaviour based on five functional ego states; critical parent, nurturing parent, adult, free child, and adapted child (AC). Twelve patients (30.0%) had previous history of repeated (two or more) HF hospitalization. Most of them (75%) had a history of at least one or more re‐hospitalizations related to inadequate self‐care. Patients with repeated HF hospitalization had significantly lower AC score, which represents uncooperative and uncompromising behaviours, compared with those without repeated HF hospitalization (P < 0.05). There were no significant differences in other parameters, including PHQ‐9, between the two groups. Conclusions Low AC ego state was associated with high prevalence of repeated hospitalization in patients with HF. Assessing ego functions may be helpful to tailor educational approaches in these patients.

Abstract
BACKGROUND No previous studies have explored how closely women follow their psychotropic drug regimens during pregnancy. This study aimed to explore patterns of and factors associated with low adherence to psychotropic medication during pregnancy. METHODS Multinational web-based study was performed in 18 countries in Europe, North America, and Australia. Uniform data collection was ensured via an electronic questionnaire. Pregnant women were eligible to participate. Adherence was measured via the 8-item Morisky Medication Adherence Scale (MMAS-8). The Beliefs about Prescribed Medicines Questionnaire (BMQ-specific), the Edinburgh Postnatal Depression Scale (EPDS), and a numeric rating scale were utilized to measure women's beliefs, depressive symptoms, and antidepressant risk perception, respectively. Participants reporting use of psychotropic medication during pregnancy (n = 160) were included in the analysis. RESULTS On the basis of the MMAS-8, 78 of 160 women (48.8%, 95% CI: 41.1-56.4%) demonstrated low adherence during pregnancy. The rates of low adherence were 51.3% for medication for anxiety, 47.2% for depression, and 42.9% for other psychiatric disorders. Smoking during pregnancy, elevated antidepressant risk perception (risk≥6), and depressive symptoms were associated with a significant 3.9-, 2.3-, and 2.5-fold increased likelihood of low medication adherence, respectively. Women on psychotropic polytherapy were less likely to demonstrate low adherence. The belief that the benefit of pharmacotherapy outweighed the risks positively correlated (r = .282) with higher medication adherence. CONCLUSIONS Approximately one of two pregnant women using psychotropic medication demonstrated low adherence in pregnancy. Life-style factors, risk perception, depressive symptoms, and individual beliefs are important factors related to adherence to psychotropic medication in pregnancy.

Abstract
Illness perceptions can influence the coping strategies used in response to HIV-related stressors, and ultimately patients' clinical status. With this work, we aimed to: (1) identify illness perception-related profiles of HIV-positive patients; (2) evaluate the association between the profiles, illness-related coping strategies, HIV-progression biomarkers (CD4+ cell counts and viral load) and antiretroviral therapy use. Data about illness perceptions, HIV-related coping strategies and HIV-progression biomarkers (CD4+ and viral load) were collected from 248 Italian HIV-positive patients. Three latent classes ("high," "moderate" and "low" influence perception) that differed on consequences, emotional representation, personal control and identity were identified. A greater perception of illness influence was associated with dysfunctional coping strategies (e.g., passive coping and alcohol use), and greater viral load was observed among patients with high and moderate influence perception. In conclusion, patients with detectable or high viral load may show a greater perception of illness influence (i.e., consequences), which is associated with dysfunctional coping strategies in response to HIV-related stressors.

Abstract
RATIONALE, AIMS AND OBJECTIVES To translate in German the 8-item Morisky Medication Adherence Scale (MMAS-8D). To validate it against objective and subjective measures of adherence in cardiovascular patients with polypharmacy. METHODS A standard forward-backward procedure was used to translate the MMAS-8 into German. Validation took place on a convenience sample of ambulatory patients on chronic antiplatelet therapy between June 2010 and June 2011. Objective adherence was obtained from electronically monitored multi-drug punch cards. Internal consistency was assessed using Cronbach's alpha coefficient, construct validity using exploratory factor analyses and correlations between MMAS-8D and related measures. Convergent validity was assessed with a subjective questionnaire about beliefs about medicines (BMQ Specific, two sub-scales). RESULTS A total of 70 patients were included (mean age 65.7 ± 9.9 years; 31.4% women). The mean score of the MMAS-8D was 7.5 (SD 0.8; range 4.5-8). Moderate internal consistency (alpha = 0.31) was observed due to multidimensionality of the scale. Factor analysis yielded four components that accounted for 71.7% of the total variance. Convergent validity was supported by significant correlations with BMQ Necessity (r = 0.31, P < 0.01), BMQ Concerns (r = -0.16, P < 0.05) and with electronic adherence reports (U-values 44 and 471, P < 0.05). Platelet aggregation values were within therapeutic range for 80% of the patients. Blood values of the antiplatelet agent within therapeutic range were associated with a higher MMAS-8D score (U-value 125, P < 0.05). CONCLUSIONS The German MMAS-8 appears to be a reliable instrument to catch medication adherence in cardiovascular patients. It may be useful in patients with chronic therapy for detecting non-adherence.

Abstract
BACKGROUND Adherence to combination antiretroviral therapy (ART) is a key predictor of the success of human immunodeficiency virus (HIV) treatment, and is potentially amenable to intervention. Insight into predictors or correlates of non-adherence to ART may help guide targets for the development of adherence-enhancing interventions. Our objective was to review evidence on predictors/correlates of adherence to ART, and to aggregate findings into quantitative estimates of their impact on adherence. METHODS We searched PubMed for original English-language papers, published between 1996 and June 2014, and the reference lists of all relevant articles found. Studies reporting on predictors/correlates of adherence of adults prescribed ART for chronic HIV infection were included without restriction to adherence assessment method, study design or geographical location. Two researchers independently extracted the data from the same papers. Random effects models with inverse variance weights were used to aggregate findings into pooled effects estimates with 95% confidence intervals. The standardized mean difference (SMD) was used as the common effect size. The impact of study design features (adherence assessment method, study design, and the United Nations Human Development Index (HDI) of the country in which the study was set) was investigated using categorical mixed effects meta-regression. RESULTS In total, 207 studies were included. The following predictors/correlates were most strongly associated with adherence: adherence self-efficacy (SMD = 0.603, P = 0.001), current substance use (SMD = -0.395, P = 0.001), concerns about ART (SMD = -0.388, P = 0.001), beliefs about the necessity/utility of ART (SMD = 0.357, P = 0.001), trust/satisfaction with the HIV care provider (SMD = 0.377, P = 0.001), depressive symptoms (SMD = -0.305, P = 0.001), stigma about HIV (SMD = -0.282, P = 0.001), and social support (SMD = 0.237, P = 0.001). Smaller but significant associations were observed for the following being prescribed a protease inhibitor-containing regimen (SMD = -0.196, P = 0.001), daily dosing frequency (SMD = -0.193, P = 0.001), financial constraints (SMD -0.187, P = 0.001) and pill burden (SMD = -0.124, P = 0.001). Higher trust/satisfaction with the HIV care provider, a lower daily dosing frequency, and fewer depressive symptoms were more strongly related with higher adherence in low and medium HDI countries than in high HDI countries. CONCLUSIONS These findings suggest that adherence-enhancing interventions should particularly target psychological factors such as self-efficacy and concerns/beliefs about the efficacy and safety of ART. Moreover, these findings suggest that simplification of regimens might have smaller but significant effects.

Abstract
OBJECTIVE The "Beliefs about Medicines Questionnaire" (BMQ) assess balance of necessity and concern of medicines. The BMQ has been translated from English to many languages. However, the original meaning of statements, such as "My medicine is a mystery to me", may be lost in translation. The aim of this study is to compare three Scandinavian translations of the BMQ. (1) How reliable are the translations? (2) Are they still valid after translation? METHODS Translated Norwegian, Swedish and Danish versions of the BMQ were scrutinized by three native Scandinavian researchers. Linguistic differences and ambiguities in the 5-point Likert scale and the BMQ statements were compared. RESULTS In the Scandinavian translations, the Likert scale expanded beyond the original version at one endpoint (Swedish) or both endpoints (Danish). In the BMQ statements, discrepancies ranged from smaller inaccuracies toward completely different meaning. Some dissimilarities reflect different cultural beliefs about medicines. CONCLUSION When translating questionnaires, bilingual researchers should scrutinize translations across similar languages to address content validity across different countries and languages. PRACTICE IMPLICATIONS Our findings are of relevance to other BMQ translations in non-English countries, as direct comparisons between different translations might not be reliable or valid.

Abstract
Clinicians make a variety of assessments about their clients, from judging personality traits to making diagnoses, and a variety of methods are available to do so, ranging from observations to structured interviews. A large body of work demonstrates that from a brief glimpse of another's nonverbal behavior, a variety of traits and inner states can be accurately perceived. Additionally, from these "thin slices" of behavior, even future outcomes can be predicted with some accuracy. Certain clinical disorders such as Parkinson's disease and facial paralysis disrupt nonverbal behavior and may impair clinicians' ability to make accurate judgments. In certain contexts, personality disorders, anxiety, depression, and suicide attempts and outcomes can be detected from others' nonverbal behavior. Additionally, thin slices can predict psychological adjustment to divorce, bereavement, sexual abuse, and well-being throughout life. Thus, for certain traits and disorders, judgments from a thin slice could provide a complementary tool for the clinician's toolbox.

Abstract
OBJECTIVES Several cross-sectional studies suggest that psychosocial factors are associated with non-adherence to chronic preventive maintenance medication (CPMM); however, results from longitudinal associations have not yet been systematically summarized. Therefore, the objective of this study was to systematically synthesize evidence of longitudinal associations between psychosocial predictors and CPMM non-adherence. MATERIALS AND METHODS PUBMED, EMBASE, CINAHL, and PsychINFO databases were searched for studies meeting our inclusion criteria. The reference lists and the ISI Web of Knowledge of the included studies were checked. Studies were included if they had an English abstract, involved adult populations using CPMM living in Western countries, and if they investigated associations between psychosocial predictors and medication non-adherence using longitudinal designs. Data were extracted according to a literature-based extraction form. Study quality was independently judged by two researchers using a framework comprising six bias domains. Studies were considered to be of high quality if ≥four domains were free of bias. Psychosocial predictors for non-adherence were categorized into five pre-defined categories: beliefs/cognitions; coping styles; social influences and social support; personality traits; and psychosocial well-being. A qualitative best evidence synthesis was performed to synthesize evidence of longitudinal associations between psychosocial predictors and CPMM non-adherence. RESULTS Of 4,732 initially-identified studies, 30 (low-quality) studies were included in the systematic review. The qualitative best evidence synthesis demonstrated limited evidence for absence of a longitudinal association between CPMM non-adherence and the psychosocial categories. The strength of evidence for the review's findings is limited by the low quality of included studies. CONCLUSION The results do not provide psychosocial targets for the development of new interventions in clinical practice. This review clearly demonstrates the need for high-quality, longitudinal research to identify psychosocial predictors of medication non-adherence.

Abstract
BACKGROUND Patients' beliefs about treatment influence treatment engagement and adherence. The Necessity-Concerns Framework postulates that adherence is influenced by implicit judgements of personal need for the treatment (necessity beliefs) and concerns about the potential adverse consequences of taking it. OBJECTIVE To assess the utility of the NCF in explaining nonadherence to prescribed medicines. DATA SOURCES We searched EMBASE, Medline, PsycInfo, CDSR/DARE/CCT and CINAHL from January 1999 to April 2013 and handsearched reference sections from relevant articles. STUDY ELIGIBILITY CRITERIA Studies using the Beliefs about Medicines Questionnaire (BMQ) to examine perceptions of personal necessity for medication and concerns about potential adverse effects, in relation to a measure of adherence to medication. PARTICIPANTS Patients with long-term conditions. STUDY APPRAISAL AND SYNTHESIS METHODS Systematic review and meta-analysis of methodological quality was assessed by two independent reviewers. We pooled odds ratios for adherence using random effects models. RESULTS We identified 3777 studies, of which 94 (N = 25,072) fulfilled the inclusion criteria. Across studies, higher adherence was associated with stronger perceptions of necessity of treatment, OR = 1.742, 95% CI [1.569, 1.934], p<0.0001, and fewer Concerns about treatment, OR = 0.504, 95% CI: [0.450, 0.564], p<0.0001. These relationships remained significant when data were stratified by study size, the country in which the research was conducted and the type of adherence measure used. LIMITATIONS Few prospective longitudinal studies using objective adherence measures were identified. CONCLUSIONS The Necessity-Concerns Framework is a useful conceptual model for understanding patients' perspectives on prescribed medicines. Taking account of patients' necessity beliefs and concerns could enhance the quality of prescribing by helping clinicians to engage patients in treatment decisions and support optimal adherence to appropriate prescriptions.

Abstract
CONTEXT AND OBJECTIVES The Beliefs about Medicines Questionnaire (BMQ-Specific) has proven useful for measuring patients' beliefs and associating them with non-adherence to treatment in several illness groups. The aim was to cross-culturally adapt the BMQ-Specific into Portuguese for the general population of medicine users. DESIGN AND SETTING Cross-sectional study conducted among users of public hospitals and outpatient clinics in Guarda and Covilhã, Portugal. METHODS The BMQ-Specific was translated using international recommendations for performing cross-cultural adaptation and was administered to 300 patients. An initial principal component analysis (PCA) was conducted with the extraction criterion of eigenvalue > 1.0, followed by a second PCA with restriction to two components. Reliability was assessed by calculating Cronbach's alpha coefficient. RESULTS The mean scores obtained for the Necessity and Concerns subscales of the Portuguese BMQ-Specific were 19.9 (standard deviation, SD = 2.8) (range 10 to 25) and 17.7 (SD = 3.9) (range 6 to 30), respectively. The first PCA produced an unstable three-component structure for the Portuguese BMQ-Specific. The final PCA solution yielded a two-component structure identical to the original English version (a five-item Necessity and a six-item Concerns subscale), and explained 44% of the variance. Cronbach's alpha for the complete Portuguese BMQ-Specific was 0.70, and 0.76 and 0.67 for the Necessity and Concerns subscales, respectively. CONCLUSION A cross-culturally adapted Portuguese version of the BMQ-Specific questionnaire for use among the general population of medicine users was obtained, presenting good internal consistency and component structure identical to the original English version.

Beliefs about chelation among thalassemia patients. Health Qual Life Outcomes 2012; 10:148.

Abstract
Background Understanding patients’ views about medication is crucial to maximize adherence. Thalassemia is a congenital blood disorder requiring chronic blood transfusions and daily iron chelation therapy. Methods The Beliefs in Medicine Questionnaire (BMQ) was used to assess beliefs in chelation in thalassemia patients from North America and London in the Thalassemia Longitudinal Cohort (TLC) of the Thalassemia Clinical Research Network (TCRN). Chelation adherence was based on patient report of doses administered out of those prescribed in the last four weeks. Results Of 371 patients (ages 5-58y, mean 24y), 93% were transfused and 92% receiving chelation (26% deferoxamine (DFO; a slow subcutaneous infusion via portable pump), 63% oral, 11% combination). Patients expressed high “necessity” for transfusion (96%), DFO chelation (92%) and oral chelation (89%), with lower “concern” about treatment (48%, 39%, 19% respectively). Concern about oral chelation was significantly lower than that of DFO (p<0.001). Self-reported adherence to chelation was not associated with views about necessity or concerns, but negatively correlated with perceived sensitivity to DFO (Sensitive Soma scale; r=−0.23, p=0.01) and side effects of oral chelation (r=−0.14, p=0.04). High ferritin iron levels, potentially indicating lower adherence, were found in 41% of patients reporting low necessity of oral chelation compared to 24% reporting high necessity (p=0.048). Concerns about treatment were associated with lower quality of life and more symptoms of anxiety and depression. Conclusions Despite their requirement for multimodal therapy, thalassemia patients have positive views about medicine, more so than in other disease populations. Patients may benefit from education about the tolerability of chelation and strategies to effectively cope with side effects, both of which might be beneficial in lowering body iron burden.

Abstract
We investigated the feasibility of using mobile phone text messaging (SMS) to promote adherence to antiretroviral therapy among HIV-infected pregnant women recently diagnosed with HIV. Seven HIV-positive women (15-33 weeks gestation) from two urban antenatal clinics received mobile phones and were invited to use text messaging to discuss HIV, health and pregnancy over a 12-week period. All participants were connected to each other and to a clinician who guided the group and answered questions via group SMS messaging. A total of 1018 individual messages were sent regarding medical and psychosocial topics related to HIV and mother-to-child HIV transmission. Participants sent an average of 16 messages per enrolled, technology-problem-free week. Half the messages (51%) concerned medical information, and the remainder concerned social comments or addressed psychological matters. Four post-intervention interviews with participants revealed overall satisfaction and participants recommended that the group be offered in the future. The pilot project's anonymity, non-rigid nature and remote access allowed it to overcome stigma and logistical challenges where a conventional support intervention would probably have failed.

Abstract
The purpose of this cross-sectional research study was to examine factors affecting medication adherence in Thai individuals with schizophrenia. The Common-Sense Model of Illness Representation was used to guide the study. Two hundred twenty-five subjects met the inclusion criteria and were interviewed. Variables of interest focused on experience of medication side effects, therapeutic alliance, social support, illness representation, and behavior change with medication adherence. Results indicated that therapeutic alliance and the experience of medication side effects enhanced illness representation, which in turn led to an intention to change adherence behavior. Social support did not alter illness representation or adherence behavior. Because illness representation positively influenced patients' intention to change adherence behavior, mental health nurses should promote patients' perception about their illness to enhance medication adherence.

Abstract
Headache is the most common neurological symptom presenting to general practitioners (GPs). Identifying factors predicting outcome in patients consulting their GPs for headache may help GPs with prognosis and choose management strategies which would improve patient care. We followed up a cohort of patients receiving standard medical care, recruited from 18 general practices in the South Thames region of England, approximately 9 months after their initial participation in the study. Of the baseline sample (N=255), 134 provided both full baseline and follow-up data on measures of interest. We determined associations between patients' follow-up scores on the Headache Impact Test-6 and baseline characteristics (including headache impact and frequency scores, mood, attributions about psychological/medical causes of their headaches, satisfaction with GP care and illness perceptions). Greater impact and stronger beliefs about the negative consequences of headaches at baseline were the strongest predictors of poor outcome at follow-up.

Abstract
This study examined psychosocial correlates of health literacy (HL) scores among older patients with coronary heart disease (CHD). A cross-sectional survey assessed psychosocial factors relating to the following: self-efficacy (i.e., perception of ability to perform a specified behavior) for diet, exercise, medication, and for a future attempt to quit smoking; social support; social stigma; appointment attendance; knowledge of heart problems; and understanding of health information. Health literacy was measured by the Rapid Estimate of Adult Literacy in Medicine (REALM). Of 321 patients, 70 had a REALM score in the low HL range (<60). When adjusting for demographics, a lower REALM score was significantly associated with reports of increased difficulty understanding health information (p < .001), less knowledge of heart problems (p = .002), increased discomfort about asking for explanations of health information (p = .014), less support with discussing health problems (p = .020). Patients with CHD and low HL are likely to face psychosocial challenges when managing their health problems. In order to encourage these individuals to seek help, health professionals need to be aware of the psychosocial characteristics of patients with low HL. These individuals may need behavioral support to increase both their self-efficacy and their understanding of their medical condition.

Abstract
BACKGROUND Medical mistrust is prevalent among African Americans and may influence health care behaviors such as treatment adherence. We examined whether a specific form of medical mistrust-HIV conspiracy beliefs (eg, HIV is genocide against African Americans)-was associated with antiretroviral treatment nonadherence among African American men with HIV. METHODS On baseline surveys, 214 African American men with HIV reported their agreement with 9 conspiracy beliefs, sociodemographic characteristics, depression symptoms, substance use, disease characteristics, medical mistrust, and health care barriers. Antiretroviral medication adherence was monitored electronically for one month postbaseline among 177 men in the baseline sample. RESULTS Confirmatory factor analysis revealed 2 distinct conspiracy belief subscales: genocidal beliefs (eg, HIV is manmade) and treatment-related beliefs (eg, people who take antiretroviral treatments are human guinea pigs for the government). Both subscales were related to nonadherence in bivariate tests. In a multivariate logistic regression, only treatment-related conspiracies were associated with a lower likelihood of optimal adherence at one-month follow-up (odds ratio = 0.60, 95% confidence interval = 0.37 to 0.96, P < 0.05). CONCLUSIONS HIV conspiracy beliefs, especially those related to treatment mistrust, can contribute to health disparities by discouraging appropriate treatment behavior. Adherence-promoting interventions targeting African Americans should openly address such beliefs.

Abstract
UNLABELLED RATIONALE, AIMS, OBJECTIVES: The Illness Perception Questionnaire (IPQ) was designed as a measure of illness perception and has been used extensively for measuring the perceptions of people with physical illness. Latterly modified versions of the IPQ have been used to measure the illness perceptions of people with mental health problems and their carers. This study examined the utility of a modified version of the IPQ to measure changes in mental health practitioners' illness perceptions about schizophrenia after undertaking psychosocial intervention training. METHOD A total of 245 mental health practitioners who undertook psychosocial intervention training completed a modified version of the IPQ before and after training. The structure of the questionnaire was tested using confirmatory factor analysis. The internal consistency of sub-scales embedded in the instrument was also examined. RESULTS The hypothesized structure failed to account for the data. Model fit indices revealed a poor fit to the data across all models evaluated. Cronbach's alpha revealed a number of sub-scales in the instrument to have mediocre internal consistency characteristics. CONCLUSIONS The modified version of the IPQ is not suitable for evaluating the impact of psychosocial intervention training on changes in illness perceptions of schizophrenia in mental health practitioners. However, the study has highlighted the need to develop a valid and reliable measure to assess the illness perceptions health professionals have of patients in their care.

Abstract
OBJECTIVE To translate the Beliefs about Medicines Questionnaire (BMQ) into Italian and explore the utility of the Necessity-Concerns Framework in explaining treatment non-adherence in four chronic illness groups in Italy. METHODS 449 patients with chronic illness (depression, asthma, diabetes and cardiac disease) were approached at outpatient clinics in Turin and asked to complete Italian translations of the BMQ and the Medication Adherence Report Scale. RESULTS 427 patients consented to participate in the study. The BMQ demonstrated good internal consistency, with Cronbach's alphas of 0.78 (Necessity subscale) and 0.72 (Concerns subscale). Participants were divided into four attitudinal groups based on their responses to the BMQ: 59% Accepting (high Necessity, low Concerns), 29% ambivalent (high Necessity, high Concerns), 8% Indifferent (low Necessity, low Concerns) and 4% Skeptical (low Necessity, high Concerns). Those in the Accepting group reported the highest adherence to medication and those in the Skeptical group the lowest (p50.01). DISCUSSION The BMQ has been successfully translated and validated in Italian. This study provides support for the Necessity-Concerns Framework in explaining medication non-adherence in chronic illness. Interventions that address low perceived need for treatment and concerns about potential adverse effects of treatment are likely to facilitate optimal use of medicines.

Abstract
OBJECTIVE To conceptualize, develop, and provide preliminary psychometric evidence for the Adherence Estimator--a brief, three-item proximal screener for the likelihood of non-adherence to prescription medications (medication non-fulfillment and non-persistence) for chronic disease. RESEARCH DESIGN AND METHODS Qualitative focus groups with 140 healthcare consumers and two internet-based surveys of adults with chronic disease, comprising a total of 1772 respondents, who were self-reported medication adherers, non-persisters, and non-fulfillers. Psychometric tests were performed on over 150 items assessing 14 patient beliefs and skills hypothesized to be related to medication non-adherence along a proximal-distal continuum. Psychometric tests included, but were not limited to, known-groups discriminant validity at the scale and item level. The psychometric analyses sought to identify: (1) the specific multi-item scales that best differentiated self-reported adherers from self-reported non-adherers (non-fulfillers and non-persisters) and, (2) the single best item within each prioritized multi-item scale that best differentiated self-reported adherers from self-reported non-adherers (non-fulfillers and non-persisters). RESULTS The two rounds of psychometric testing identified and cross-validated three proximal drivers of self-reported adherence: perceived concerns about medications, perceived need for medications, and perceived affordability of medications. One item from each domain was selected to include in the Adherence Estimator using a synthesis of psychometric results gleaned from classical and modern psychometric test theory. By simple summation of the weights assigned to the category responses of the three items, a total score is obtained that is immediately interpretable and completely transparent. Patients can be placed into one of three segments based on the total score--low, medium, and high risk for non-adherence. Sensitivity was 88%--of the non-adherers, 88% would be accurately classified as medium or high risk by the Adherence Estimator. The three risk groups differed on theoretically-relevant variables external to the Adherence Estimator in ways consistent with the hypothesized proximal-distal continuum of adherence drivers. CONCLUSIONS The three-item Adherence Estimator measures three proximal beliefs related to intentional non-adherence (medication non-fulfillment and non-persistence). Preliminary evidence of the validity of the Adherence Evidence supports its intended use to segment patients on their propensity to adhere to a newly-prescribed prescription medication. The Adherence Estimator is readily scored and is easily interpretable. Due to its brevity and transparency, it should prove to be practical for use in everyday clinical practice and in disease management for adherence quality improvement. Study limitations related to sample representation and self reports of chronic disease and adherence behaviors were discussed.
