ABSTRACT Objective: to develop and validate a scale to measure the quality of life of people living with HIV in Brazil. Method: methodological study conducted in a Brazilian care service specialized in sexually transmissible infections/AIDS between 2017 and 2019 addressing people living with HIV. The scale’s development and validation included exploratory factor analysis to describe its factor structure and psychometric properties, Multitrait-Multimethod analysis to verify its validity and Cronbach’s alpha for reliability. Floor and ceiling effects were described according to the responses’ frequency distribution. Results: a total of 460 people living with HIV participated. Most were men 276 (60.0%) aged 43 on average (SD=±12.4). The Exploratory Factor Analysis revealed four factors with 39.9% of explained variance. The total scale presented satisfactory reliability with a Cronbach’s alpha equal to 85.0%. Most items presented satisfactory convergent and divergent validity. The presence of floor and ceiling effects were found. The scale’s final version was composed of 45 items. Conclusion: the Quali-HIV Scale is a valid and reliable tool to measure the quality of life of people living with HIV.

The aim of the study is to determine the reliability and validity of the Greek version of the Food Allergy Quality of life Questionnaire- Child Form (FAQLQ-CF). After linguistic validation, the Greek FAQLQCF, Food Allergy Independent Measure (FAIM) and Pediatric Quality of Life Inventory (PedsQL™) were used by a physician to interview children diagnosed with food allergy and aged 8-12 via telephone. Cronbach’s alpha was used to evaluate reliability, and factor analysis to assess construct validity. The correlation between FAQLQ-CF and FAIM was moderate (rho=0.509, P<0.001) and internal consistency was strong (Cronbach’s alpha 0.905). FAQLQ-CF discriminated well each question’s contribution to children’s quality of life deterioration (32- 80%), each child’s quality of life (17-89%), children differing in doing things with others (total score 3.55 vs 2.57, difference =0.98 > minimal clinical importance difference = 0.5; P<0.001), but not children differing in reporting anaphylaxis. The total FAQLQ-CF score correlated with the total PedsQL™ score and with the score of one of PedsQL™ subscales, demonstrating convergent validity. Factor analysis uncovered an underlying structure of four factors, explaining 50% of the variance. We can conclude that Greek FAQLQ-CF is a reliable, valid, discriminant tool for interviewing food allergic children aged 8- 12, detecting those in need for immediate care.

Abstract Background We conducted the study to compare the psychometric properties of the English version of the Questionnaire and the Bahasa Malaysia (Malay Language) version regarding the vision-related Quality of Life of patients with cataracts. Methods The Malay version was translated by two independent translators who were well versed in both languages. We carried out a cross-sectional study collecting data between June 2017 and March 2018 in the pre-operative Eye Clinic of Hospital Melaka with 224 respondents (mean age 66.8 years) and another 204 respondents (mean age 64.3 years) participating in the English version and Malay version of the Questionnaire respectively. Methods used to validate the standard questionnaire included the use of construct validity via factor analysis and the deployment of reliability test through assessment of internal consistency via Cronbach’s alpha. Results We observed both English and Bahasa Malaysia versions to have high reliability with Cronbach’s alpha values of 0.90 and above in factors on difficulty with activities and responses to vision problems. Exploratory factor analysis performed revealed that the three-factor model fits the data well for the English version of the questionnaire - difficulty with activities (23.81 % of variance), responses to vision problem (22.22 % of variance) and general health and vision (14.68 % of variance). The Bahasa Malaysia version of the questionnaire produced three factors with two of the factors resembling the factors from the original version of the questionnaire - difficulty with activities (24.3 % of variance) and responses to vision problem (23.7 % of variance). Item response theory analysis revealed that these factors for both English and Bahasa Malaysia versions comprised of adequately fitted items. Conclusion The present study observed that both the English and Bahasa Malaysia versions of the NEI VFQ-25 have comparable construct validity to the original American version. With high validity and reliability, the tool shall be able to provide health care providers the assessment of impact due to cataract and other ophthalmic conditions on the vision-related quality of life of ophthalmic patients.

(1) Objective: To assess the reliability and validity of the simplified Chinese version of the brief Diabetes Quality of Life (DQoL) questionnaire in measuring health-related quality of life (HRQoL) in Chinese type 2 diabetes (T2D) patients. (2) Methods: A cross-sectional validation study including 277 patients was conducted at a tertiary hospital in Shanghai, China during April–May, 2018. The English brief DQoL was forward and back-translated into simplified Chinese. The expert interview, exploratory factor analysis (EFA), and Spearman correlation with the 5-level version of EuroQoL-5 (EQ-5D-5L) were employed to establish its validity. The internal reliability was assessed by Cronbach’s alpha. Participants were also stratified into subgroups to evaluate if the Chinese brief DQoL had more test effectiveness in a specific subpopulation. (3) Results: No items were removed from the original English brief DQoL based on the results of factor analysis and expert interview. The Spearman coefficient revealed a low-moderate inverse correlation between DQoL and EQ-5D-5L index and visual analogue scale (VAS), respectively (ρ1 = −0.364, p < 0.0001; ρ2 = −0.514, p < 0.0001). The Cronbach’s alpha coefficient of the final scale was 0.731. (4) Conclusions: The simplified Chinese version of the brief DQoL questionnaire showed reasonable reliability and validity, suggesting its potential appropriateness for evaluating quality of life in Chinese T2D patients. More future efforts should be made to generalize the application of the findings.

Abstract Funding Acknowledgements Type of funding sources: None. OnBehalf Centre for Heart Rhythm Disorders Background Education is critical to empower individuals to self-monitor and manage their condition. Significant variability exists in the provision of education for atrial fibrillation (AF), whilst individual patient factors including health literacy and education level attainment may impact on knowledge levels. Objective assessment of knowledge  may help to target education to areas of need, and result in improved patient outcomes. Objective To describe the development and validation of a knowledge questionnaire for AF. Methods A multidisciplinary expert team of healthcare professionals developed the questionnaire, in conjunction with consumers, with question content based upon areas deemed most critical to AF and related self-management. The multiple choice questionnaire consists of 20 items, each worth 5 points, to give a total score out of 100. The questionnaire assesses five domains specific to AF: general knowledge, complications, medications, risk factors and action. The questionnaire was developed in English. The questionnaire was tested on 10 randomly selected patients with AF for face validity and 19 healthcare professionals for content validity. The final version was completed by 454 individuals with AF. Exploratory factor analysis was used to determine construct validity with factor loadings of 0.40 and above considered acceptable. Reliability was assessed using Cronbach’s alpha, with a value greater than 0.7 acceptable. Results Face and content validity were considered acceptable, after minor changes to wording. The cohort of 454 individuals with AF had a mean age of 66.9 ± 12 years and 43% were female. Mean (SD) total score was 57.7 ± 15.8. Exploratory factor analysis was undertaken using the principal components method. This resulted in a Kaiser–Meyer–Olkin Measure of Sampling Adequacy of .64 and a Bartlett"s Test of Sphericity being significant at 0.00. Seven factors were selected and analysed using principal component analysis with varimax rotation. All items loaded on one of the seven factors. Internal consistency demonstrated a Cronbach’s alpha of 0.65. Conclusion The Atrial Fibrillation Knowledge Questionnaire is a valid measure to assess knowledge in individuals with AF.

Abstract Background Limited attention is devoted to the improvement of the quality of life of patients suffering from the negative consequences of Sickle cell disease (SCD). Our study focuses on the evaluation of the performance of the WHOQOL-BREF as a tool to measure the quality of life of SCD Patients in Bahrain. Methods We conducted a cross-sectional study that enrolled 273 SCD patients selected using a simple random sampling technique from primary health-care centers in Bahrain in 2019. A designed questionnaire including the WHOQOL-BREF was filled by the patients during face-to-face interviews in the health centers. The reliability of the WHOQOL-BREF was assessed by standardized Cronbach’s alpha coefficient, and the validity was measured by convergent validity, principal component analysis and confirmatory factor analysis. Results The WHOQOL-BREF had good internal consistency as Cronbach’s alpha coefficient for the overall scale was 0.91. The convergent validity results indicated that the correlation coefficients values for all scale domains are significantly correlated at α < 0.01. Confirmatory factor analysis found that the four-domain structure produced a robust fit to the data. Conclusions The WHOQOL-BREF tool has high internal consistency and validity in assessing the quality of life of Sickle Disease patients in Bahrain.

Abstract Background Oral mucositis is one of the serious complications of chemotherapy and/or radiotherapy that significantly affects the quality of patients’ life. The Oropharyngeal Mucositis-Specific Quality-of-Life questionnaire (OMQoL) is an acceptable instrument for measuring the quality of life in these patients. The aim of this study was to evaluate the validity and reliability of the Persian version of OMQoL questionnaire. Methods This study was a cross-sectional and multi-centric research. After translation from English to Persian, back translation, and cultural adaptation, the Persian version of the questionnaire was prepared. One hundred forty-four patients suffering from oral mucositis referred to three different university affiliated hospitals related to Zahedan, Kerman and Tehran Universities of Medical Sciences, were participated in this study. Then the questionnaire was completed by trained interviewers. The reliability was assessed by Cronbach’s alpha coefficient, and validity was measured through factor analysis, and construct validity (including discriminant validity, and convergent validity) methods. Results Cronbach's alpha in all dimensions was higher than 0.9 that indicated a perfect internal consistency. The results of factor analysis indicated that the dimensions specified in the Persian version were the same as the original version (Factor loading of all items > 0.4). The correlation coefficient for all items was more than 0.75, and the convergence validity was 100% in all dimensions. Conclusion The results of this study showed that the reliability, and validity of Persian version of OMQoL were acceptable, which can be used to measure the quality of life in patients with oral mucositis.
