Satisfaction Scale

Background: To assess the health-related quality of life (HRQoL) of oral anticoagulant therapy users, different types of instruments are available, either general or specific tools like Duke Anticoagulation Satisfaction Scale (DASS). These tools allow the clinician to adjust the treatment regimen to focus on increasing anticoagulation adherence and reduce adverse clinical outcomes. This study aims to validate the translated Arabic version of DASS to assess the satisfaction level of patients using oral anticoagulants in the Arab population.Methods: The Duke Anticoagulation satisfaction scale (DASS) was translated into the Arabic language using MAPI group services. DASS was administered to 505 patients receiving anticoagulation with warfarin or apixaban. The generic scale measuring the quality of life EQ-5D-5L was also administered. Psychometric properties were assessed by Confirmatory Factor Analysis, internal consistency (Cronbach’s Alpha), exploratory factor analysis, convergent and divergent validity, and the correlation between the DASS and demographic variables, clinical characteristics, and the EQ-5D-5L instrument.Results: 439 subjects answered all the questions. From a total of 25 items, 22 grouped into three factors (limitations, positive impact, and negative impact). Each factor had good internal consistency (Cronbach Alpha 0.78–0.88). All the three factors correlated consistently with EQ-5D-5L measuring generic quality of life.Conclusion: The psychometric properties of the Arabic DASS version were comparable to the original English version. The Arabic version of the DASS showed very good reliability and validity. It can be used by health care professionals in other settings of anticoagulation clinics to assess patient’s satisfaction and limitations to anticoagulant treatment.

Background: No specific questionnaire that evaluates Health-Related Quality Of Life (HRQOL) in individuals with obesity is available in the Arabic language. The aim of this study was therefore to propose and examine the validity and reliability of an Arabic language version of the ORWELL 97, a validated obesity-related HRQOL questionnaire. Methods: The ORWELL 97 questionnaire was translated from English to Arabic language and administered to 318 Arabic-speaking participants (106 from clinical and 212 from community samples), and underwent internal consistency, test–retest reliability, construct and discriminative validity analysis. Results: Internal consistency and the test–retest reliability were excellent for ORWELL 97 global scores in the clinical sample. Participants with obesity displayed significantly higher ORWELL 97 scores than participants from the community sample, confirming the good discriminant validity of the questionnaire. Confirmatory factor analysis in the clinical sample revealed a good fit for a modified two-factor structure. Conclusion: Overall, the Arabic version of the ORWELL 97 can be considered validated in Arabic adult patients with obesity, paving the way to further assessment of its responsiveness in measuring changes in health-related quality of life associated with obesity treatment.

Background Quality of life (QoL) is considered a key treatment outcome in bipolar disorder (BD) across research, clinical, and self-management contexts. Web-based assessment of patient-reported outcomes offer numerous pragmatic benefits but require validation to ensure measurement equivalency. A web-based version of the Quality of Life in Bipolar Disorder (QoL.BD) questionnaire was developed (QoL Tool). Objective This study aimed to evaluate the psychometric properties of a web-based QoL self-report questionnaire for BD (QoL Tool). Key aims were to (1) characterize the QoL of the sample using the QoL Tool, (2) evaluate the internal consistency of the web-based measure, and (3) determine whether the factor structure of the original version of the QoL.BD instrument was replicated in the web-based instrument. Methods Community-based participatory research methods were used to inform the development of a web-based adaptation of the QoL.BD instrument. Individuals with BD who registered for an account with the QoL Tool were able to opt in to sharing their data for research purposes. The distribution of scores and internal consistency estimates, as indicated by Cronbach alpha, were inspected. An exploratory factor analysis using maximum likelihood and oblique rotation was conducted. Inspection of the scree plot, eigenvalues, and minimum average partial correlation were used to determine the optimal factor structure to extract. Results A total of 498 people with BD (349/498, 70.1% female; mean age 39.64, SD 12.54 years; 181/498, 36.3% BD type I; 195/498, 39.2% BD type II) consented to sharing their QoL Tool data for the present study. Mean scores across the 14 QoL Tool domains were, in general, significantly lower than that of the original QoL.BD validation sample. Reliability estimates for QoL Tool domains were comparable with that observed for the QoL.BD instrument (Cronbach alpha=.70-.93). Exploratory factor analysis supported the extraction of an 11-factor model, with item loadings consistent with the factor structure suggested by the original study. Findings for the sleep and physical domains differed from the original study, with this analysis suggesting one shared latent construct. Conclusions The psychometric properties of the web-based QoL Tool are largely concordant with the original pen-and-paper QoL.BD, although some minor differences in the structure of the sleep and physical domains were observed. Despite this small variation from the factor structure identified in the QoL.BD instrument, the latent factor structure of the QoL Tool largely reproduced the original findings and theoretical structure of QoL areas relevant to people with BD. These findings underscore the research and clinical utility of this instrument, but further comparison of the psychometric properties of the QoL Tool relative to the QoL.BD instrument is warranted. Future adaptations of the QoL Tool, including the production of an app-based version of the QoL Tool, are also discussed.

Background/Aims: Independence and social engagement are important outcomes for people with dementia. The aim of this study was to conduct an in-depth psychometric assessment of the Engagement and Independence in Dementia Questionnaire (EID-Q), a measure of social independence. Methods: This was an observational study at five NHS sites across England. Participants completed the EID-Q alongside additional measures. Psychometric analysis included internal consistency, test-retest reliability, convergent validity, and factor analyses. Results: A total of 225 people living with dementia completed the study. Internal consistency was excellent (α = 0.921) and the measure remained moderately stable over a 1-week period (ICC = 0.768). Significant correlations were observed between quality of life (r = 0.682) and depression (r = –0.741; both p < 0.001), indicating the importance of these concepts for wellbeing in dementia. Factor analysis indicated the presence of five factors which loaded onto a second order two-factor solution. These latent factors were named “sense of independence” and “social engagement.” Conclusions: The EID-Q demonstrated acceptable psychometric properties and the factor solution had an adequate model fit. The strong correlations suggest that social independence is strongly related to depression and quality of life. Future work will entail an analysis of responsiveness to intervention and further large-scale work.

Abstract Background Patients Generated index (PGI) is one of the individualized measures used to measure the quality of life (QOL) in people with different chronic conditions including multiple sclerosis (MS). However, the psychometric properties of the Arabic version of the PGI have not been fully established in Jordanian living with MS. Therefore, the objective of this study is to identify what matters to Jordanian living with MS and to contribute evidence toward the psychometric properties of the Arabic version of the PGI. Method A total of 75 participants with MS completed three QOL measures; PGI, the Patient Determined Disease Steps (PDDS), and EQ-5D. Generalized Estimating Equations (GEE) were used to compare the total score of three QOL measures. Bland-Altman plot and Spearman’s correlation coefficient were used to study the relationships and differences between the PGI and the other study measures (PDDS and EQ-5D). Results Only 66 (88%) of the participants were able to complete the PGI. Overall, 36 areas of QOL concern were nominated by the participants using the PGI with the top 3 areas were an emotional function (47%), involuntary movement reaction functions (45.5%) and walking (44%). The average global score of the PGI was lower (34±22) than the global score of the EQ-5D (69±23) and the PDDS (68±24).PGI had a moderate correlation with EQ-5D and PPDS. Conclusion The Arabic version of the PGI is a feasible and acceptable measure among Jordanian with MS and it captures a wide spectrum of important areas that contribute to QOL than EQ-5D and PDDS. PGI could improve the decision making and guide health-care professionals to provide appropriate intervention programs to reduce the burdens from MS disease and improve QOL.

Abstract Background Osteoarthritis (OA) is a debilitating multifactorial degenerative rheumatic disease affecting millions of people around the globe. The osteoarthritis quality of life scale (OAQoL), originally produced in the English language, is an important tool used to assess the overall impact of OA and its treatment on the patient’s quality of life. Purpose The purpose of the study was to translate and validate the OAQoL in the Arabic language in order to use it on the Saudi population. Methodology A bilingual panel comprising four healthcare professionals and one external certified medical translator translated the English version of the OAQoL to the Arabic language. A back translation was subsequently performed by two English-speaking translators and any differences were resolved by conferring with the original panel. The qualitative research was performed through cognitive debriefing interviews (CDIs) with 59 native Arabic patients who had clinically and radiologically confirmed osteoarthritis of any joint. The internal consistency of the 22 items was derived by leveraging the Cronbach’s Alpha coefficient. Results 59 participants were included in the study, and more than half (52.5%) of them were men. The response rate was 100% and the mean time taken to answer the questionnaire was 10.5 min. The average Intraclass Correlation Coefficient (ICC) and Cronbach’s Alpha were determined to be 0.93 each, indicating that all the items in the OAQoL were significantly interrelated. Conclusion The translated Arabic version of the OAQoL questionnaire used in this study is a reliable and consistent tool that showed good comprehensibility and internal consistency.

Introduction Chemotherapy-induced nausea and vomiting is a serious complication of cancer treatment that compromises patients’ quality of life and treatment adherence, which necessitates regular assessment. Therefore, there is a need to assess patient-reported nausea and vomiting using a validated scale among Arabic speaking cancer patient population. The objective of this study was to translate and validate the Functional Living Index-Emesis (FLIE) instrument in Arabic, a patient-reported outcome measure designed to assess the influence of chemotherapy-induced nausea and vomiting on patients’ quality of life. Methods Linguistic validation of an Arabic-language version was performed. The instrument was administered to cancer patients undergoing chemotherapy in a tertiary hospital's cancer center in Saudi Arabia. Results One-hundred cancer patients who received chemotherapy were enrolled. The participants’ mean age was 53.3 ± 14.9 years, and 50% were female. Half of the participants had a history of nausea and vomiting with previous chemotherapy. The Cronbach coefficient alpha for the FLIE was 0.9606 and 0.9736 for nausea and vomiting domains, respectively, which indicated an excellent reliability for the Arabic FLIE. The mean FLIE score was 110.9 ± 23.5, indicating no or minimal impact on daily life (NIDL). Conclusions The Arabic FLIE is a valid and reliable tool among the Arabic-speaking cancer population. Thus, the Arabic version of the FLIE will be a useful tool to assess the quality of life among Arabic speaking patients receiving chemotherapy. Additionally, the translated instrument will be a useful tool for future research studies to explore new antiemetic treatments among cancer patients.

Abstract Background In clinical practice, quality of life measures can be used alongside some types of assessment to give valuable information that can identify areas that influence an individual and help the clinician make the best healthcare choices. This study aimed to investigate the psychometric properties of the Arabic version of the 12-item short-form health survey (SF-12) in a sample of Lebanese adults. Methods This cross-sectional study performed between July and November 2019 recruited 269 participants. Cronbach’s alpha was used to assess the reliability of the SF-12 questionnaire, and a factor analysis using the principal component analysis was performed to confirm its construct validity. Results The mean score for the “physical component summary (PCS-12)” was 50.27 ± 8.94 (95 % CI: 49.18–51.36) and for the “Mental component summary (MCS-12)” was 44.95 ± 12.17 (95 % CI: 43.47–46.43). A satisfactory Cronbach’s alpha was found for the two components: MCS (α = 0.707) and PCS (α = 0.743). The principal component analysis converged over a two-factor solution (physical and mental), explaining a total variance of 55.75 %. Correlations between the SF-12 scales and single items were significant, showing a good construct validity. The “physical functioning”, “role physical”, “bodily pain”, and “general health” subscales were highly associated with “PCS-12”, while the “vitality”, “social functioning”, “role emotional”, and “mental health” subscales were more associated with MCS-12. Conclusions The Arabic version of the SF-12 is a reliable, easy-to-use, and valid tool to measure health-related quality of life in the general population. Future studies using a larger sample size and focusing on questionnaire psychometric properties are necessary to confirm our findings.

Background: Family quality of life (FQoL), just like individual quality of life, has become a priority outcome in the policies and services received by persons with intellectual and developmental disabilities (IDD) and their families. Conceptualizing, measuring, and theorizing FQoL has been the object of investigation in recent decades. The goal of this paper is to present a revision of the Spanish Family Quality of Life Scales, the CdVF-E < 18 and the CdVF-E >18, and describe the FQoL of Spanish families with a member with IDD. Methods: The sample included a total of 548 families with a member under 18 years old and 657 families with a member over 18. Based on an Exploratory Factor Analysis (EFA) firstly and a Confirmatory Factor Analysis (CFA) secondly, the two scales’ psychometric properties were explored. Results: The CdVF-ER < 18 and the CdVF-ER > 18 comprise 5 dimensions, containing 35 and 32 items, respectively, and they show good validity and reliability. The families obtained a high FQoL score, although some differences exist between the dimensions on which families with children under and over 18 score highest and lowest. Conclusion: The characteristics of the revised scales facilitate their use by professionals, administrations, and services.
