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.

Rationale, aims and objectives: The Morisky Medication Adherence Scale (MMAS-8) is a self-reported scale used in assessing medication adherence in patients on chronic therapy. Medication adherence is a neglected area of research in Sri Lanka and in this study we have attempted to validate the Sinhala translation of the MMAS-8 to determine medication adherence among patients stabilized on lithium therapy for bipolar disorder (BD).Methods: The MMAS-8 was translated to Sinhala with standard forward and backward translations from English to Sinhala. Patients with BD on stable doses of lithium were administered the Sinhala version of the MMAS-8. During the same visit, the serum lithium concentration was measured. Criterion validity was assessed using therapeutic serum lithium concentrations as the gold standard. Internal consistency was assessed using Cronbach’s alpha and Spearman’s rank correlation was used to assess test-retest reliability.Results: From a sample of 240 patients, 82.1% were considered adherent, with serum lithium concentration >0.4 mmol/L. The mean MMAS-8 score was 6.95±1.3. According to the MMAS-8 scale, 13.3% reported low adherence while 43.3% reported medium and high adherence equally using MMAS cut offs <6, 6 to<8 and 8 respectively. The scale sensitivity to identify adherence at a cut-off score of 6 was 86.3%. The test–retest reliability value was 0.708 (p<0.001). Internal consistency was found with a Cronbach’s alpha value of 0.608 for the 8 items of the scale.Conclusion: The Sinhala version of MMAS-8 can be used as a sensitive instrument to identify medication adherence in patients with bipolar disorders.

Abstract Background Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients. Methods A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to &lt; 6 (low), 6 to &lt; 8 (medium), 8 (high). Results In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence. Conclusions MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high. Key messages This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.

Abstract Background: Based on the concept of “Daseinsverabschiedung”, an anthropological theory of “Anticipated Farewell to Existence” (AFE) was suggested on the basis of six grounding dimensions (“derived in AFE”): selfhood (“expiration of the time of existence”), interpersonality (“altruistic preoccupation”), temporality (“struggle for acceptance”), corporeality (“wounded physical integrity”), worldliness (“reconciliation with own existence”), and transcendence (“self-transcendence”). The purpose of the study is to investigate the extent to which the relevance of these anthropological dimensions differs between people in different stages of life, especially those facing their own death.Methods: The sample (N=485) consists of dying individuals in palliative wards and hospices (n=121); old people living in nursing homes not suffering from a mortal disease (n=62); young adults (n=152), and middle-aged adults (n=150). The relevance of anticipated farewell to existence was measured by means of the “Anticipated Farewell to Existence Questionnaire” (AFEQT). Further assessment tools: Big Five Inventory (BFI-10), Life Attitude Profile (LAP-R), Eastern Cooperative Oncology Group (ECOG), and Basic Documentation for Psycho-Oncology (PO-Bado). The internal consistency of the AFEQT was assessed using Cronbach’s alpha and convergent validity by means of dimensions of LAP-R. Differences in the relevance of the AFEQT dimensions among stages of life were estimated by means of multiple regression models.Results: According to Cronbach’s alpha, the internal consistency of the AFEQT subscales was sufficient for the whole sample. Convergent validity with dimensions of LAP-R was found for young and middle-aged participants. Dying people scored significantly higher for most of the dimensions than young and middle-aged as well as elderly people. Personality traits of “oenness” and “agreeableness” are positively associated with the extent of assessed dimensions of AFEQT.Conclusions: Anthropological reflections on the structure of human beings, which is activated or actualized in a special way in the face of death, can provide a framework for practice facing a humanization of medicine at the end of life, considering real experiences, possible needs, and underlying human conditions when facing end of life. The dimensions proposed can be taken into account in a sensitive way by supporting dialogues with dying people and their relatives.Trial registration: observational study.

Nowadays, it is common for people to look for health care information on the internet. The eHealth Literacy Scale (eHEALS) is commonly used to measure eHealth literacy. As of the publication of this study, the Indonesian version for eHEALS has not been published even though eHealth literacy is necessary, especially in the current COVID-19 pandemic. We aimed to evaluate the validity and reliability of the Indonesian version of eHEALS (I-eHEALS). A total of 100 respondents in East Java were involved in this cross-sectional study. Pearson-product moment correlation method and construct validity were used to validate the results. The reliability was determined based on the Cronbach’s alpha internal consistency measurement and intraclass correlation coefficient (ICC). The Pearson correlation analysis results are significantly higher ( r > 0.254, p < 0.01) compared to the critical value table. Single factors accounting for 57.66% variance in the scales exhibit a unidimensional latent structure. The internal consistency between items is excellent as shown by the Cronbach’s alpha coefficient (0.91). The ICC analysis shows an acceptable result (0.552, p < 0.01). The I-eHEALS is valid and reliable to be used for evaluating the eHealth literacy of the Indonesian population.
