Abstract
BACKGROUND Nursing incivility, defined as disrespectful behaviour toward nurses, is increasingly recognized as a pressing issue that affects nurses' well-being and quality of care. However, research on the pathways linking incivility to outcomes is limited, especially in Saudi hospitals. METHODS This cross-sectional study examined relationships between perceived nursing incivility, nurse stress, patient engagement, and health outcomes in four Saudi hospitals. Using validated scales, 289 nurses and 512 patients completed surveys on exposure to incivility, stress levels, activation, and medication adherence. The outcomes included readmissions at 30 days and satisfaction. RESULTS More than two-thirds of nurses reported experiencing moderate to severe workplace incivility. Correlation and regression analyzes revealed that nursing incivility was positively associated with nursing stress. An inverse relationship was found between stress and patient participation. Serial mediation analysis illuminated a detrimental cascade, incivility contributing to increased nurse stress, subsequently diminishing patient engagement, ultimately worsening care quality. Conclusions The findings present robust evidence that nursing incivility has adverse ripple effects, directly impacting nurse well-being while indirectly affecting patient outcomes through reduced care involvement. Practical implications advocate for systemic interventions focused on constructive nursing cultures and patient empowerment to improve both healthcare provider conditions and quality of care. This study provides compelling information to inform policies and strategies to mitigate workplace mistreatment and encourage participation among nurses and patients to improve health outcomes.

Abstract
BACKGROUND Medication adherence has a major impact on reducing mortality and healthcare costs related to the treatment of cardiovascular diseases and diabetes mellitus. Selecting the best patient-reported outcome measure (PROM) among the many available for this kind of patient is extremely important. This study aims to critically assess, compare and synthesize the quality of the measurement properties of patient-reported outcome measures to assess medication adherence among patients with cardiovascular diseases and/or type 2 diabetes mellitus. METHODS This review followed the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The searches were performed in Web of Science, SCOPUS, PubMed, CINAHL, EMBASE, LILACS, PsycINFO, and ProQuest (gray literature). RESULTS A total of 110 records encompassing 27 different PROMs were included in the review. The included records were published between 1986 and 2023, most of which reported studies conducted in the United States and were published in English. None of the PROMs were classified in the category "a", thus being recommended for use due to the quality of its measurement properties. The PROMs that should not be recommended for use (category "c") are the MTA, GMAS, DMAS-7, MALMAS, ARMS-D, and 5-item questionnaire. The remaining PROMs, e.g., MMAS-8, SMAQ, MEDS, MNPS, ARMS-12, MGT, MTA-OA, MTA-Insulin, LMAS-14, MARS-5, A-14, ARMS-10, IADMAS, MAQ, MMAS-5, ProMAS, ARMS-7, 3-item questionnaire, AS, 12-item questionnaire, and Mascard were considered as having the potential to be recommended for use (category "b"). CONCLUSION None of the included PROMs met the criteria for being classified as trusted and recommended for use for patients with cardiovascular diseases and/or type 2 diabetes mellitus. However, 21 PROMs have the potential to be recommended for use, but further studies are needed to ensure their quality based on the COSMIN guideline for systematic reviews of PROMs. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42019129109.

Abstract
Background: Guidelines recommend comprehensive lifestyle change in patients with peripheral arterial disease (PAD) to prevent cardiovascular events and death. When compared with other populations, patients with PAD are less likely to receive best medical therapies (BMT). The aim of this pilot study was to integrate all aspects of BMT in an intervention program and to determine the feasibility of such an approach by highlighting strengths and obstacles of a multi-aspect intervention. Patients and methods: Patients consecutively hospitalized due to symptomatic PAD between 01 December 2021 and 28 February 2022 were included and followed for ten weeks. We randomized into a lifestyle intervention (education on BMT, a list of regional contact data for supervised exercise, weekly counselling by phone for ten times) vs. standard of care (one contact to talk about BMT). Vascular Quality of Life Questionnaire - 6 (VascuQoL-6) was used to collect patient reported outcomes. Results: Of 50 eligible patients 40 agreed to participate (32.5% female, 72.5 years in mean). During follow-up nine patients dropped out (4 in intervention group vs. 5). As for risk factor modification one patient was able to reach a normal weight body-mass-index (BMI) and nine reduced weight. Two patients stopped smoking, three reduced their consumption. The reported adherence to medication was a hundred percent. No patient attended supervised exercise therapy but eight trained at a home-based setting according to guidelines. The mean score of VascuQoL-6 at follow-up was higher in the intervention group compared to the control group (17.4 vs. 13.8 points) at last contact with both groups increasing from baseline. Conclusions: This pilot study followed 40 patients for up to 10 weeks after inpatient treatment while we randomized a multi-aspect lifestyle intervention versus standard of care. Thereby, the current study illustrated the numerous obstacles and provided pragmatic solutions for the planning of studies on BMT in this target population.

Abstract
Health literacy (HL) is an essential component of public health. Few tools are used to measure HL in Arabic-speaking countries, essentially the Short Test of Functional Health Literacy in Adults and the Single Item Literacy Screener. The new 12-item version of the European Health Literacy Survey Questionnaire (HLS-Q12), has not been validated in the Arabic language. This study aimed to translate the English version of HLS-Q12 into Arabic, test its structure and explain any variance in HLS-Q12 scores, allowing its use in Arabic-speaking healthcare contexts. A forward-backward translation was adopted. Reliability was assessed using Cronbach's α. Confirmatory factor analysis (CFA) and Rasch Model evaluated the model fit of the Arabic version of HLS-12. The effects of different patient-related variables on HLS-Q12 scores were tested using linear regression. A total of 389 patients visiting the site hospital outpatient clinics participated in the study. HLS-Q12 mean ± SD score was 35.8 ± 5.0, 50.9% of the participants showed an intermediate HL score. Good reliability (α = 0.832) was observed. CFA confirmed the scale unidimensionality. Rasch analysis indicated HLS-Q12 items to be within the fit acceptable thresholds except for Item 12. The only item that displayed unordered response categories was Item 4. Most of the items were considered relatively easy by respondents. Linear regression revealed age, education, healthcare-related education and income to have effects significantly different from zero on HLS-Q12 score. Interventions targeting the most health-disparate groups of individuals with characteristics contributing to lower HL, are needed.

Abstract
Introduction Digital health measures promise to further improve the quality of cardiovascular care but have not yet been widely implemented in routine care. The research project Digital preventive measures for arterial hypertension (DiPaH) will systematically identify structural and individual factors in different stakeholders that influence the use of digital preventive measures in patients with arterial hypertension in Germany. Special focus is given to remote and sparsely populated areas, the age-specific impact, as well as influence of digital health literacy. Methods and analysis The DiPaH project is an exploratory cross-sectional study with a mixed-methods design, in which written surveys and interviews with patients and physicians will be conducted. In addition, secondary data from a health insurance company will be analyzed. In module 1, individuals from the database of the health insurance company with confirmed arterial hypertension will be interviewed (1,600 questionnaires, 30 interviews). Module 2 includes users of digital prevention offers and apps (400 questionnaires, 40 interviews) and in module 3, family physicians and cardiologists will be interviewed (400 questionnaires, 40 interviews). In a final module, the overall results will be analyzed and recommendations for interventions in clinical care will be derived. Discussion The DiPaH project will contribute to a patient-oriented and demand-based improvement of arterial hypertension prevention services in health care. Challenges and barriers will be analyzed and the respective target groups identified based on their prevention needs and social characteristics to enable a patient-centered implementation of digital prevention of arterial hypertension and cardiovascular services in general, and finally to improve cardiovascular outcomes.

Abstract
The Morisky Green Levine (MGL) adherence scale is a 4-item tool used for the detection of medication nonadherence among patients with chronic health conditions. Despite being widely used in Arabic-speaking research contexts, it has never been validated in Arabic language. The aim of this study was to translate and validate the MGL tool into Arabic. A standard forward-backward process was used to translate the questionnaire. Cronbach’s alpha coefficient was measured to assess internal consistency of the scale. The test-retest reliability measured the consistency of participants’ responses over time. Construct validity was evaluated by Explanatory factor analysis (EFA); Kaiser-Meyer-Olkin value and Bartlett’s test of sphericity were determined. Convergent validity was assessed using a preexisting medications Arabic Adherence Assessment Tool (AAAT). The model fit was evaluated using confirmatory factor analysis (CFA). Associations between the MGL scale scores and the patient demographic/clinical characteristics were tested by linear regressions. A total of 201 participants were included into the study. The MGL scale categorization revealed that 20.9%, 59.2% and 19.9% of the participants had high, moderate and low levels of adherence respectively. Adequate internal consistency (alpha = 0.593) was observed. A significant strong ICC and Pearson’s correlations were generated between responses at time 1 and time 2. EFA results elucidated the suitability of the data for factor analysis. Pearson’s coefficient (r) revealed a significant strong correlation between MGL scale and AAAT. CFA results confirmed a good fit for the suggested model. Linear regression revealed higher number of medications, more frequent outpatient clinic visits and not experiencing medication adverse effect factors significantly associated with better adherence. The Arabic version of MLG scale is a reliable valid tool to assess adherence among Arabic-speaking communities. Implementing interventions targeting patients not compliant to regular clinic visits and those at higher risk of experiencing medication side effects can greatly enhance medication adherence.

Abstract
OBJECTIVE To evaluate the reliability and validity of the Chinese version of the eight-item Morisky Medication Adherence Scale (MMAS-8) in Chinese patients with systemic lupus erythematosus (SLE). METHODS The survey was conducted with a consecutive sampling of 158 Chinese SLE patients attending public hospitals from January to March 2021. We used the translated Chinese version of the MMAS-8 to collect related data. Reliability, item, and factor analyses were used to test the reliability and validity of the MMAS-8 scale in the selected patients. The internal consistency reliability was evaluated using Cronbach's α coefficient. Test-retest reliability was assessed using intraclass correlation coefficients (ICCs) in a subset of 30 participants. Construct validity was evaluated using confirmatory factor analysis and correlations between the Self-efficacy for Appropriate Medication Use Scale (SEAMS) and related measures. RESULTS The internal consistency reliability of the Chinese version of the MMAS-8 was high (Cronbach's α = 0.817), and the test-retest reliability was excellent (intraclass correlation = 0.947; P < 0.001). There were significant differences in the F test and t test between the two extreme groups before and after the ranking of 27% of the questionnaire scores (P < 0.001). The Kaiser-Meyer-Olkin (KMO) value of construct validity was 0.860. The spherical test value of Bartlettgers was 417.8822. Factor analysis yielded three components that accounted for 69.375% of the total variance. Exploratory factor analysis identified three dimensions of the Chinese version of the MMAS-8. In terms of criterion validity, the correlation of the MMAS-8 score in SEAMS indicated that the convergent validity was good (r = 0.926; P < 0.001). CONCLUSIONS This study shows that the Chinese version of the Medication Adherence Scale-8 is a reliable and valid tool for assessing medication adherence in Chinese SLE patients. Key Points • Many factors affect medication adherence in SLE patients. • Many questionnaires measure medication adherence levels. • There is a lack of reliable validation of medication adherence questionnaires specifically for SLE patients.

Abstract
BACKGROUND AND OBJECTIVE Several medication adherence patient-reported outcome measures (MA-PROMs) are available for use in patients with cardiovascular disease (CVD); however, little evidence is available on the most suitable MA-PROM to measure medication adherence in patients with CVD. The aim of this systematic review is to synthesise the measurement properties of MA-PROMs for patients with CVD and identify the most suitable MA-PROM for use in clinical practice or future research in patients with CVD. METHODS An electronic search of nine databases (PubMed, MEDLINE, CINAHL, ProQuest Health and Medicine, Cochrane Library, PsychInfo, Scopus, Embase, and Web of Science) was conducted to identify studies that have reported on at least one of the measurement properties of MA-PROMs in patients with CVD. The methodological quality of the studies included in the systematic review was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. RESULTS A total of 40 MA-PROMs were identified in the 84 included studies. This review found there is a lack of moderate-to-high quality evidence of sufficient content validity for all MA-PROMs for patients with CVDs. Only eight MA-PROMs were classified in COSMIN recommendation category A. They exhibited sufficient content validity with very low-quality evidence, and moderate-to-high quality evidence for sufficient internal consistency. The 28 MA-PROMs that meet the requirements for COSMIN recommendation category 'B' require further validation studies. Four MA-PROMs including Hill-Bone Compliance Medication Scale (HBMS), the five-item Medication Adherence Report Scale (MARS-5), Maastricht Utrecht Adherence in Hypertension (MUAH), and MUAH-16 have insufficient results with high quality evidence for at least one measurement property and consequently are not recommended for use in patients with CVD. Two MA-PROMs (Adherence to Refills and Medications Scale [ARMS] and ARMS-7) are comprehensive and have moderate to high quality evidence for four sufficient measurement properties. CONCLUSION From the eight MA-PROMs in COSMIN recommendation category A, ARMS and ARMS-7 were selected as the most suitable MA-PROMs for use in patients with CVD. They are the most comprehensive with be best quality evidence to support their use in clinical practice and research.

Abstract
Aim. Development, testing and validation of the original questionnaire “Adherence Scale” (AS) in the PRIORITY and ANTEY observational studies (OS).Materials and methods. The OS PRIORITY assessed adherence to statins in 298 patients with high and very high cardiovascular risk for 3 months. The OS ANTEY assessed adherence to oral anticoagulants in 201 patients with non-valvular atrial fibrillation for 1 year. Adherence was assessed using the original AS questionnaire, for which external validation was performed (with the calculation of the Cohen's Kappa coefficient). The reference methods were the validated questionnaire and direct medical interview. And internal validation was performed (consistency of questions on the AS using Spearman's correlation analysis). The sensitivity, specificity (ROC analysis) and retest reliability of the adherence scale (Cronbach's alpha) were also determined.Results. In the OS PRIORITY Cohen's kappa for the AS and the reference method of direct medical survey was 0.76 (high consistency), and for the AS and the reference method of the validated questionnaire=0.28 (low consistency). High internal consistency of the questionnaire questions (correlation coefficient=0.78, p<0.0001) confirms the internal validity of the adherence scale. Evaluation of the main characteristics of the modified AS in the OS ANTEY showed high consistency between the results of the AS and the validated questionnaire: Cohen's kappa=0.94 (high external validity of the AS). The retest reliability of the AS was 0.76 (Cronbach's alpha). The internal consistency of the questionnaire was confirmed by a strong and statistically significant correlation between the test questions: Spearman's correlation coefficient=0.80, p<0.0001. The sensitivity of the test, determined using the ROC analysis, was 89%, and the specificity was 62%.Conclusion. The developed and tested new original questionnaire (modified version) – the AS – showed high indicators of reliability, validity and sensitivity. This ensures its reliability and ease of use for assessing various types of adherence and determining the leading factors of non-adherence, and also allows its use in scientific studies and clinical practice.

[PMID: 34360062 PMCID: PMC8345617 DOI: 10.3390/ijerph18157768] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 07/15/2021] [Accepted: 07/17/2021] [Indexed: 11/16/2022]
Abstract
Background: Pharmacists are increasingly involved in strategies to fight antimicrobial resistance by ensuring optimised antibiotic (AB) use, including adherence support. Successful adherence interventions should be tailored to patients’ barriers and validated instruments are needed. This study aimed to identify adherence barriers to AB treatment, develop a self-report questionnaire, and validate it in outpatients. Method: Adherence barriers were identified through a systematic literature search and focus group discussion. Unmodifiable and irrelevant barriers were excluded from further processing. A validation study assessed the questionnaire’s internal reliability and construct validity by comparing the questionnaire’s score with electronically monitored adherence data. Results: A 15-item questionnaire was created. Overall, 68 patients were included in the construct validation analysis (60.3% female). The mean consecutive taking adherence was 88% and the most frequently reported barriers were “worries about side-effects” (37%) and “having swallowing difficulties” (19%). Three items were excluded from the questionnaire, which was supported by an increase of Cronbach’s alpha (0.69 to 0.70). The 12-item version’s score correlated significantly with medication adherence rate (r = −0.34, p < 0.01). Conclusion: The self-report questionnaire is a reliable and valid tool to pre-emptively assess adherence barriers in outpatients prescribed ABs. In the future, appropriate adherence interventions can be matched to barriers and tested in a pilot intervention study.

Abstract
Background: Adherence to treatment is an important factor in the management of diabetic patients. The aim of this study was to examine the psychometric properties of the 8-item Morisky Medication Adherence Scale (MMAS-8) among type 2 diabetes. Methods: This study carried out in Family Medicine Clinics (FMCs) in Tabriz, North West of Iran from May to September 2018. A total of 320 patients suffering from Type 2 diabetes were included. Content and face validity of the Persian version of MMAS-8 were quantitatively evaluated. The Cronbach's alpha and intra-class correlation (ICC) were calculated to assess the reliability. Exploratory factor analysis (EFA) was used to assess the construct validity of the questionnaire. Results: Content and face validity of the Persian version of MMAS-8 were confirmed. Good internal consistency (Cronbach’s a = 0.83) and test–retest reliability (ICC= 0.87, P<0.001) were found. According to the results of the EFA, Persian version of MMAS-8 among diabetic patients had two dimensions: stopping to take medication due to the forgetfulness and for reasons other than forgetfulness. Conclusion: The Persian version of the MMAS-8 is a high valid and reliable questionnaire to screen medication adherence of Persian-speaking patients with diabetes.

Abstract
Background Medication adherence is essential for improving the health outcomes of patients. Various patient-reported outcome measures (PROMs) have been developed to measure medication adherence in patients. However, no study has summarized the psychometric properties of these PROMs to guide selection for use in clinical practice or research. Objective This study aims to evaluate the quality of the PROMs used to measure medication adherence. Methods This study was guided by the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines. Relevant articles were retrieved from the EMBASE, PubMed, Cochrane Library, Web of Science, and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. The PROMs were then evaluated based on the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. Results A total of 121 unique medication adherence PROMs from 214 studies were identified. Hypotheses testing for construct validity and internal consistency were the most frequently assessed measurement properties. PROMs with at least a moderate level of evidence for ≥5 measurement properties include the Adherence Starts with Knowledge 20, Compliance Questionnaire-Rheumatology, General Medication Adherence Scale, Hill-Bone Scale, Immunosuppressant Therapy Barrier Scale, Medication Adherence Reasons Scale (MAR-Scale) revised, 5-item Medication Adherence Rating Scale (MARS-5), 9-item MARS (MARS-9), 4-item Morisky Medication Adherence Scale (MMAS-4), 8-item MMAS (MMAS-8), Self-efficacy for Appropriate Medication Adherence Scale, Satisfaction with Iron Chelation Therapy, Test of Adherence to Inhalers, and questionnaire by Voils. The MAR-Scale revised, MMAS-4, and MMAS-8 have been administered electronically. Conclusions This study identified 121 PROMs for medication adherence and provided synthesized evidence for the measurement properties of these PROMs. The findings from this study may assist clinicians and researchers in selecting suitable PROMs to assess medication adherence.

Abstract
Background Medication adherence is important in managing the progression of chronic diseases. A promising approach to reduce cognitive burden when measuring medication adherence lies in the use of computer‐adaptive tests (CATs) or in the development of shorter patient-reported outcome measures (PROMs). However, the lack of an item bank currently hampers this progress. Objective We aim to develop an item bank to measure general medication adherence. Methods Using the preferred reporting items for systematic review and meta-analysis (PRISMA), articles published before October 2019 were retrieved from PubMed, Embase, CINAHL, the Cochrane Library, and Web of Science. Items from existing PROMs were classified and selected (“binned” and “winnowed”) according to standards published by the Patient-Reported Outcomes Measurement Information System (PROMIS) Cooperative Group. Results A total of 126 unique PROMs were identified from 213 studies in 48 countries. Items from the literature review (47 PROMs with 579 items for which permission has been obtained) underwent binning and winnowing. This resulted in 421 candidate items (77 extent of adherence and 344 reasons for adherence). Conclusions We developed an item bank for measuring general medication adherence using items from validated PROMs. This will allow researchers to create new PROMs from selected items and provide the foundation to develop CATs.

Questionnaires and scores for assessing medication adherence — advantages and disadvantages of the diagnostic method in research and actual clinical practice.

Abstract
The problem of medication adherence is still relevant, and the search for a reliable method for its diagnosis continues. One of the most convenient and promising ways to assess medication adherence, both in research and actual clinical practice, is the use of various questionnaires and scores. Currently, several dozen different questionnaires and scores are presented in Russia and other countries. All of them are indirect methods of adherence assessment and are characterized by subjectivity. The article presents data on the most famous and widely used foreign adherence scales (the 4- and 8-item Morisky Medication Adherence Scale (MMAS-4 and MMAS-8), Hill-Bone, SEAMS, BMQ, MARS, etc.) and several questionnaires proposed by Russian authors (the National Society of Evidence-based Pharmacotherapy Adherence Scale, the Quantitative Adherence Questionnaire and the National Questionnaire of Treatment Compliance). The main characteristics of the described scales, their advantages, disadvantages and prospects for use in studies and clinical practice are considered. There are following conclusions: 1) none of the current questionnaires is devoid of subjectivity; 2) almost all questionnaires overestimate medication adherence, do not fully diagnose nonadherence, and often determine only specific type of adherence; 3) even validated questionnaires, which used in patients with different diseases in various countries, can have different values of sensitivity, specificity and reliability — from excellent to very poor; 4) in this regard, the results should be skeptically and cautiously interpreted; 5) in actual clinical practice, preference should be given to concise scales that include no more than 10 questions, with a simple scoring system, preferably validated with using well-known criteria from large clinical trials; 6) to improve the diagnosis accuracy, usage of several available methods for assessing medication adherence is recommended.

Abstract
BACKGROUND Patients' health beliefs are essential to improve medication adherence among patients with hypertension. OBJECTIVE Our objective was to examine the relationship between (1) patients' beliefs about hypertension, medication, and self-efficacy and medication adherence and (2) medication adherence and blood pressure control in Oman. METHODS This cross-sectional study included 215 participants with hypertension. Participants completed 4 questionnaires (Arabic version) to measure medication adherence, beliefs about hypertension severity, beliefs about medication, and self-efficacy. Bivariate and multivariate logistic regression was used to conduct the analyses. RESULTS Higher self-efficacy (odds ratio [OR], 2.59; 95% confidence interval [CI], 1.54-4.37), stronger beliefs about medication necessity (OR, 1.98; 95% CI, 1.21-3.23), increased age (OR, 1.06; 95% CI, 1.03-1.10), and fewer medication concerns (OR, 0.34; 95% CI, 0.20-0.57) were related to high medication adherence. Moreover, uncontrolled blood pressure was less likely in participants with high medication adherence (OR, 0.47; 95% CI, 0.24-0.93). CONCLUSIONS Patients' beliefs are important consideration to improve medication adherence. Clinically, patients' beliefs should be assessed, and strategies to improve medication adherence should incorporate beliefs as a key component to improve antihypertensive medication adherence. Patient education and counseling regarding hypertension and necessity and side effects of medications are important to maximize positive beliefs and improve medication adherence.

Abstract
Background and Objectives: A particular problem in cardiology is poor adherence to pharmacological treatment among patients with hypertension. It is known that approximately half of these patients do not use their medications as prescribed by their doctor. Patients may choose not to follow the doctor's recommendations and regularly do not control their blood pressure, owing to many factors. A convenient method for measuring the level of adherence is the Morisky Medication Adherence Scale, which also provides insight into possible remedies for low adherence. We investigated their therapy, knowledge about the disease and its control, and demographic differences to assess the adherence of patients with hypertension. Materials and Methods: This was a cross-sectional observational study. Data were collected through a survey of 12 pharmacies in Latvia. The study involved 187 participants with hypertension. Results: The prevalence of non-adherence was 46.20% in Latvia. The oldest patients were the most adherent (p = 0.001, β = 0.27). The higher the self-rated extent from 0 to 10, to which the patient takes their antihypertensives exactly as instructed by their physician, the higher the level of adherence (p < 0.0001, β = 0.38), where at "0", the patient does not follow physician instructions at all, and at "10", the patient completely follows the physician's instructions. Non-adherent patients tend to assess their medication-taking behavior more critically than adherent patients. The longer the patient is known to suffer from hypertension, the more adherent he or she is (p = 0.014, β = 0.19). Conclusions: Medication non-adherence among patients with hypertension is high in Latvia. Further investigations are needed to better understand the reasons for this and to establish interventions for improving patient outcomes.

Abstract
BACKGROUND Nonadherence to medication therapy has been associated with poor health outcomes and increased health care costs. The literature describes pharmacists as key health care professionals in identifying and addressing nonadherence issues but does not explain how and why effective pharmacist-patient communication affects patients' medication adherence. Previously published pathways used in linking effective physician-patient communication to patient outcomes are proposed for the context of pharmacist-patient communication. OBJECTIVES To develop preliminary steps in a pharmacist communication - patient outcome pathway, adapted from a physician-patient communication pathway. METHODS This longitudinal descriptive study, which took place in a large quaternary hospital, involved hospital pharmacists and patients. Patients' assessment of pharmacist communication behaviours and reporting of patient satisfaction occurred after the pharmacist-patient consultation. Medication-taking behaviour questionnaires were administered before the consultation and again 4 weeks after discharge. Developing the preliminary pathway (based on previously established physician communication pathways) involved 2 steps, with investigation of the following associations: (1) between patient-reported effective communication by pharmacists, as per the Communication Accommodation Theory (CAT), and patient satisfaction; and (2) between patient-reported pharmacist communication and satisfaction and patients' medication-taking behaviour. RESULTS Twelve pharmacists and 48 patients participated. For step 1, almost all patient-reported pharmacist communication behaviours were positively correlated with patient satisfaction statements. Strong associations between CAT-related pharmacist communication behaviours and patient satisfaction highlighted the pharmacists' behaviours that are important to patients and necessary for effective conversations to take place. In step 2, there were fewer correlations of medication-taking behaviour indices with pharmacist communication behaviours and patient satisfaction. CONCLUSIONS This study showed how a preliminary pharmacist communication - patient outcome pathway could be successfully adapted from existing physician communication pathways. Such pathways provide an initial platform upon which future pharmacist communication - patient outcome research can be built.

Abstract
BACKGROUND Little is known regarding the relationship between medication adherence and quality of life in heart failure patients. We therefore aimed to examine the nature of relationship between medication adherence and quality of life. METHODS A prospective, cross-sectional study of chronic heart failure patients with reduced ejection fraction was performed at a tertiary-care, university hospital in Thailand. Quality of life and medication adherence were assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and Morisky Medication Adherence Scale-8 (MMAS-8), respectively. Relationship of MLHFQ and MMAS-8 were examined using Spearman's correlation coefficient and multiple regression analysis for covariates adjustment. RESULTS Among 180 patients, 38.3%, 50.0% and 11.7% were found to have high, medium and poor adherence, respectively. For quality of life, the overall median score on the MLHFQ was relatively low. A positive relationship was identified between medication adherence and quality of life. After covariate adjustment, medication adherence was found to have the strongest relationship with quality of life, compared to other covariates. CONCLUSIONS Medication adherence has a small and positive relationship with quality of life among heart failure patients.

Abstract
INTRODUCTION AND OBJECTIVE The 8-Item Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used instruments to assess medication adherence, but a validated European Portuguese version of MMAS-8 does not exist. Our aim was to develop and validate a European Portuguese version of the MMAS-8. METHODS A process of translation and back-translation of the original MMAS-8 was performed. The questionnaire was administered in nine community pharmacies and one public hospital between March 2014 and September 2015. Adult patients taking at least one antihypertensive drug were invited to participate. A confirmatory factor analysis was performed and internal consistency, convergent validity and concurrent validity were examined. RESULTS A total of 472 patients were enrolled in the study. The mean MMAS-8 score obtained was 6.74±1.39. One hundred and thirty-two patients were classified as low adherers (28%), 181 (38.3%) as medium adherers and 159 (33.7%) as high adherers. For the factorial structure of the Portuguese version of the MMAS-8, the fit indices of the final model (chi-square [18] 48.465, p<0.001) are suggestive of very good fit, with comparative fit index 0.95, root mean square error of approximation 0.06 (90% confidence interval 0.04-0.08), and standardized root mean square residual 0.04, confirming that the construct tested was unidimensional. The Cronbach's alpha for all items was 0.60, and the translated version presents convergent validity and concurrent validity. CONCLUSION A European Portuguese version of the MMAS-8 was created that maintained a similar structure to the original MMAS-8 and good psychometric properties.

Abstract
BACKGROUND Since 2010, Swiss pharmacists have been offering their patients a Polymedication Check (PMC), a new cognitive pharmacy service in the form of a medication review for patients taking ≥4 prescribed medicines for a period >3 months. While a first publication of this project reported on the impact of the PMC on patients' adherence, the present paper focuses on humanistic outcomes. METHODS This randomized controlled trial was conducted in 54 Swiss community pharmacies. After recruitment, the intervention group underwent a PMC in the pharmacy (T-0) and 28 weeks after T-0 (T-28), while the control group did not receive the PMC until 28 weeks after the study started (T-28). A clinical psychologist, blinded to the intervention, interviewed the patients 2 weeks (T-2) and 16 weeks (T-16) after T-0. Interviewer and patient both rated patient's knowledge of own medicines use. Furthermore, patients reported satisfaction with their pharmacy and appraisal of their medicines use. The availability of a written medication plan was assessed at T-16. Acceptance of the service was measured using a patient's self-report questionnaire at T-28. RESULTS General linear model analysis for knowledge about medicines revealed a significant effect on the factor "group" (P=5.86, p=0.016), indicating that the intervention group had higher ratings for knowledge about their medication at T-2 and T-16 compared to controls. The majority (83%) of patients judged the counseling by the pharmacist as being helpful for their daily medication management. Availability of a written medication plan was comparable in both groups (52.5% vs 52.7%, p>0.05). CONCLUSION For the first time, the benefits of a complex pharmacist-led intervention were evaluated in Swiss primary care with a randomized controlled trial. The PMC increased patients' subjective knowledge of their medicines compared to no medication review. The effect remained sustainable over time. Recommendations resulting from the pharmacist-led service were highly appreciated by the patients.

Abstract
OBJECTIVES To assess subjective swallowing difficulties (SD) with medication intake and their practical consequences in patients suffering from systemic sclerosis (SSc) with a novel self-report questionnaire. DESIGN AND SETTING Based on a systematic literature review, we developed a self-report questionnaire and got it approved by an expert panel. Subsequently, we sent the questionnaire by post mail to SSc patients of the European Center for the Rehabilitation of Scleroderma Rheinfelden, Switzerland. PARTICIPANTS Patients were eligible if they were diagnosed with SSc, treated at the center, and were of age ≥18 years at the study start. MAIN OUTCOME MEASURES Prevalence and pattern of SD with oral medication intake, including localization and intensity of complaints. RESULTS The questionnaire consisted of 30 items divided into five sections Complaints, Intensity, Localization, Coping strategies, and Adherence. Of the 64 SSc patients eligible in 2014, 43 (67%) returned the questionnaire. Twenty patients reported SD with medication intake (prevalence 47%), either currently (11; 26%) or in the past that had been overcome (9; 21%). Self-reported SD were localized mostly in the larynx (43%) and esophagus (34%). They were of moderate (45%) or strong to unbearable intensity (25%). Modification of the dosage form was reported in 40% of cases with SD. Adherence was poor for 20 (47%) patients and was not associated with SD (p=0.148). CONCLUSION Our novel self-report questionnaire is able to assess the pattern of complaints linked to medication intake, that is, localization and intensity. It may serve as a guide for health care professionals in selecting the most suitable therapy option, enabling tailored counseling to reduce inappropriate medication modifications.

Abstract
Objective: To assess the internal consistency and factorial validity of the adapted French 8-item Morisky Medication Adherence Scale in assessing adherence to noninsulin antidiabetic drug treatment. Study Design and Setting: In a cross-sectional web survey of individuals with type 2 diabetes of the Canadian province of Quebec, self-reported adherence to the antidiabetes drug treatment was measured using the Morisky Medication Adherence Scale-8. We assessed the internal consistency of the Morisky Medication Adherence Scale-8 with Cronbach’s alpha, and factorial validity was assessed by identifying the underlying factors using exploratory factor analyses. Results: A total of 901 individuals completed the survey. Cronbach’s alpha was 0.60. Two factors were identified. One factor comprised five items: stopping medication when diabetes is under control, stopping when feeling worse, feeling hassled about sticking to the prescription, reasons other than forgetting and a cross-loading item (i.e. taking drugs the day before). The second factor comprised three other items that were all related to forgetfulness in addition to the cross-loading item. Conclusion: Cronbach’s alpha of the adapted French Morisky Medication Adherence Scale-8 was below the acceptable value of 0.70. This observed low internal consistency of the scale is probably related to the causal nature of the items of the scale but not necessarily a lack of reliability. The results suggest that the adapted French Morisky Medication Adherence Scale-8 is a two-factor scale assessing intentional (first factor) and unintentional (second factor) non-adherence to the noninsulin antidiabetes drug treatment. The scale could be used to separately identify these outcomes using scores obtained on each of the sub-scales.

Abstract
Background Cystic fibrosis (CF) is a life shortening disease, however prognosis has improved and the adult population is growing. Most adults with cystic fibrosis live independent lives and balance the demands of work and family life with a significant treatment burden. The aim of this study was to examine the relationships among treatment adherence, symptoms of depression and health-related quality of life (HRQoL) in a population of young adults with CF. Methods We administered three standardized questionnaires to 67 patients with CF aged 18–30 years; Morisky Medication Adherence Scale, Major Depression Inventory, and Cystic Fibrosis Questionnaire-Revised. Results There was a response rate of 77 % and a majority of the young adults (84 %) were employed or in an education program. Most participants (74 %) reported low adherence to medications. One third (32.8 %) of the participants reported symptoms of depression. HRQoL scores were especially low on Vitality and Treatment Burden, and symptoms of depression were associated with low HRQoL scores (p < 0.01) with medium to large deficits across on all HRQoL domains (Cohen’s d 0.60–1.72) except for the domain treatment burden. High depression symptom scores were associated with low adherence (r = −0.412, p < 0.001). Conclusions Despite improved physical health, many patients with CF report poor adherence, as well as impaired mental wellbeing and HRQoL. Thus, more attention to mental health issues is needed.

Abstract
BACKGROUND In 2010 the 'Polymedication Check' (PMC), a pharmacist-led medication review, was newly introduced to be delivered independently from the prescriber and reimbursed by the Swiss health insurances. This study aimed at evaluating the impact of this new cognitive service focusing on medicines use and patients' adherence in everyday life. METHODS This randomised controlled trial was conducted in 54 Swiss community pharmacies. Eligible patients used ≥4 prescribed medicines over >3 months. The intervention group received a PMC at study start (T-0) and after 28 weeks (T-28) while the control group received only a PMC at T-28. Primary outcome measure was change in patients' objective adherence, calculated as Medication Possession Ratio (MPR) and Daily Polypharmacy Possession Ratio (DPPR), using refill data from the pharmacies and patient information of dosing. Subjective adherence was assessed as secondary outcome by self-report questionnaires (at T-0 and T-28) and telephone interviews (at T-2 and T-16), where participants estimated their overall adherence on a scale from 0-100%. RESULTS AND DISCUSSION A total of 450 patients were randomly allocated to intervention (N = 218, 48.4%) and control group (N = 232, 51.6%). Dropout rate was fairly low and comparable for both groups (N Int = 37 (17.0%), NCont = 41 (17.7%), p = 0.845). Main addressed drug-related problem (DRP) during PMC at T-0 was insufficient adherence to at least one medicine (N = 69, 26.7%). At T-28, 1020 chronic therapies fulfilled inclusion criteria for MPR calculation, representing 293 of 372 patients (78.8%). Mean MPR and adherence to polypharmacy (DPPR) for both groups were equally high (MPRInt = 88.3, SD = 19.03; MPRCont = 87.5, SD = 20.75 (p = 0.811) and DPPRInt = 88.0, SD = 13.31; DPPRCont = 87.5, SD = 20.75 (p = 0.906), respectively). Mean absolute change of subjective adherence between T-0 and T-2 was +1.03% in the intervention and -0.41% in the control group (p = 0.058). The number of patients reporting a change of their adherence of more than ±5 points on a scale 0-100% between T-0 and T-2 was significantly higher in the intervention group (NImprovement = 30; NWorsening = 14) than in the control group (NImprovement = 20; NWorsening = 24; p = 0.028). CONCLUSION Through the PMC pharmacist were able to identify a significant number of DRPs. Participants showed high baseline objective adherence of 87.5%, providing little potential for improvement. Hence, no significant increase of objective adherence was observed. However, regarding changes in subjective adherence of more than ±5% the PMC showed a positive effect.

Abstract
BACKGROUND The previous Thai version of the 8-item Morisky Medication Adherence Scale (8-item MMAS) showed poor sensitivity and unacceptable internal consistency reliability. OBJECTIVES To develop and test the psychometric properties of a new medication taking behavior measure for Thai patients (MTB-Thai) including practicality, reliability and validity. METHODS This study was conducted with adult outpatients regularly taking any medicines for at least three months from three university hospitals in Bangkok, Thailand, between July 2014 and March 2015. The study was approved by the Ethical Committees of the three hospitals. Practicality was assessed by administration time and the percentage of missing data. Internal consistency and test-retest reliability were evaluated employing Cronbach's alpha and intraclass correlation coefficients (ICCs), respectively. Validity was evaluated with content, construct, convergent and known-groups validity. RESULTS Of 1156 patients, the 6-item MTB-Thai had an average administration time of 2 min and no missing data. It showed good Cronbach's alpha value of 0.76 and excellent ICCs of 0.83. The MTB-Thai showed good content validity with the item level and scale level of content validity indexes greater than the acceptable levels of 0.8 and 0.9, respectively. Both exploratory and confirmatory factor analyses showed the MTB-Thai had two domains including unintentional and intentional domains. The MTB-Thai correlated well with the overall medication adherence scale with a Pearson's correlation coefficient of 0.62 (p < 0.001). The sensitivity, specificity, positive predictive value and negative predictive value of the MTB-Thai were 76, 35, 55 and 57 %, respectively. CONCLUSION The MTB-Thai was practical, reliable and valid in assessing mediation taking behaviors in Thai patients with chronic diseases.

Abstract
Low adherence to pharmacological treatment is often associated with poor blood pressure control, but identification of nonadherent patients in outpatient settings is difficult. The aim of the study was to translate and evaluate the psychometric properties of the Polish version of the structured self-report eight-item Morisky Medication Adherence Scale (MMAS-8) among patients with hypertension. The study was conducted in a family doctor practice between January and July 2015. After a standard "forward-backward" procedure to translate MMAS-8 into Polish, the questionnaire was administered to 160 patients with hypertension. Reliability was tested using a measure of internal consistency (Cronbach's α) and test-retest reliability. Validity was confirmed using known group validity. Three levels of adherence were considered based on the following scores: 0 to <6 (low); 6 to <8 (medium); and 8 (high). Complete questionnaires were returned by 110 respondents (mean age: 60.7 years ±12.6; 54.6% were female). The mean number of pills taken daily was 3.61±4.31. The mean adherence score was 6.42± 2.0. Moderate internal consistency was found (Cronbach's α=0.81), and test-retest reliability was satisfactory (r=0.461-0.905; P<0.001). Reproducibility expressed by Cohen's κ coefficient =0.61 was good. In high-adherent patients, the percentage of well-controlled blood pressure was higher than in low-adherent patients (33.3% vs 19.1%, χ (2)=0.87, P=0.648). Psychometric evaluation of the Polish version of the MMAS-8 indicates that it is a reliable and valid measure tool to detect nonadherent patients. The MMAS-8 may be routinely used to support communication about the medication-taking behavior in hypertensive patients.
