Abstract Purpose We conducted the study to compare the validation properties of the English version of the Questionnaire and the Bahasa Malaysia (Malay Language) version regarding the Quality of Life of patients with cataracts. Methods We carried out a cross-sectional study collecting data between June 2017 and March 2018 in the pre-operative Eye Clinic of Hospital Melaka. The Malay version was translated by two independent translators who were well versed in both languages. 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 (24.28% of variance) and responses to vision problem (23.66% of variance). 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.

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.

Background: Stroke causes a wide variety of clinical manifestations that may have a negative impact on quality of life. Therefore, it is very important to use specific instruments for measuring quality of life in individuals who suffered a stroke. The aim of this study was to develop a psychometrically validated Spanish version of the Newcastle stroke-specific quality of life measure (NEWSQOL). Methods: A psychometric validation of the Spanish version of the NEWSQOL questionnaire was carried out in 159 patients. The reliability (intraclass correlation coefficient and Cronbach’s alpha coefficient), validity (factorial analysis and Spearman’s coefficient), feasibility (response rate), and the ceiling and floor effects were calculated. Results: Internal consistency showed that Cronbach’s alpha coefficient was 0.93. The test–retest reliability was high or excellent for all domains (range 0.71–0.97 p < 0.001). The response rate of the questionnaire was 100% and the average administration time was 20.5 (±7.2) min. No ceiling effect was detected and two domains (pain and vision) may have a significant potential for floor effect. Construct validity showed that all the variables are important enough to keep them all in the questionnaire. Concerning convergent construct validity, a high correlation was found with the Nottingham Health Profile, the Barthel Index, and the Modified Rankin Scale. Conclusion: The Spanish version of the NEWSQOL questionnaire is reliable, valid, and feasible to evaluate quality of life in the Spanish population.

Background: Pregnancy and childbirth are sensitive and particular periods in women’s lives. Midwives play an essential role in ensuring mother’s and fetus’s health by the recognition of the needs and complexities of this period. Midwives increase the quality of care, gain the trust of pregnant women, communicate more effectively with them, and increase their satisfaction and cooperation by following the ethical principles and standards that express their professional commitment to society. Therefore, the awareness of the principles of professional ethics and adherence to the Charter of Patients’ Rights is a critical element of the midwife’s success in ensuring mother’s and neonate’s health. Therefore, monitoring the observance of these principles by midwives, similar to other health care providers, is essential to improve the quality of services and ultimately parturients’ satisfaction. For this purpose, it is necessary to have a valid and reliable tool to assess midwives’ professional ethics status. Objectives: In this study, a questionnaire was developed to assess this issue by parturients, who are primary stakeholders in this process. Methods: This qualitative and quantitative study was performed to design a reliable and valid questionnaire evaluating midwives’ professional ethics by parturients. Based on the literature review and consultation with midwifery professors and staff, the initial questionnaire was prepared with 26 items. A survey of 15 experts evaluated the content and face validity ratio. The final questionnaire with 20 items was completed by 200 parturients hospitalized in Valiasr Hospital of Fasa University of Medical Sciences, Fars, Iran, within 2018 - 2019. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) assessed the construct validity. The reliability was confirmed by the determination of internal consistency. Results: The 26 items of the questionnaire defined in the first step were reduced to 20 items with a content validity ratio higher than 0.49 and a content validity index higher than 0.79. Using EFA and CFA, 20 items were included in two dimensions and confirmed. Its reliability was reported as 0.89 using Cronbach’s alpha. Conclusions: This study aimed to design a valid and reliable questionnaire for the assessment of midwifery professional ethics in the delivery process. One strength of the present study, compared to those of mentioned studies, is performing both EFA and CFA. In this study, some goals of EFA consist of determining questionnaire dimensions, standardizing questionnaires, reducing the items (from variables to factors), and assessing homogeneity and discrimination in construct validity. The EFA is often used in the early stages of research to collect information about the interactions in a set of variables. The obtained results revealed that the designed questionnaire is a valid and reliable tool for the evaluation of midwifery professional ethics by parturients, which can be applied in other studies in Iran.

(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 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.
