Health Qual Life Outcomes 2021; 19:91. [PMID: 33731135 PMCID: PMC7972212 DOI: 10.1186/s12955-021-01741-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2020] [Accepted: 03/10/2021] [Indexed: 11/11/2022] Open
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.

Adaptation and validation of the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire for use in Bulgaria. Rheumatol Int 2020; 40:2077-2083. [PMID: 32814987 DOI: 10.1007/s00296-020-04686-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Accepted: 08/11/2020] [Indexed: 10/23/2022]
Abstract
Rheumatoid arthritis (RA) is a chronic disease with an enormous impact on patients' quality of life. The Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire is a disease-specific measure of QoL for individuals with rheumatoid arthritis. Our aim was to adapt and validate the RAQoL for use in Bulgaria. The development of a new language version of the RAQoL consisted of three stages: translation, field testing and psychometric evaluation. The dual-panel methodology, requiring two independent panels of Bulgarian speakers, was applied to translate the UK English version of the RAQoL into Bulgarian. Face and content validity of the translated questionnaire were assessed through cognitive debriefing interviews. Lastly, the RAQoL was administered on two occasions to a random sample of RA patients to evaluate reliability and validity. At the first occasion, the SF-36 was also administered for use as a comparator scale. The RAQoL was successfully adapted into Bulgarian and considered easy to understand, acceptable and comprehensive by RA patients. A psychometric study demonstrated that the new language version has excellent internal consistency (Cronbach's alpha coefficients = 0.93 and 0.94) and test-retest reliability (a Spearman's rank correlation coefficient = 0.97). Convergent validity was established by correlating scores on the RAQoL with a comparator measure, the SF-36. A strong correlation between RAQoL scores and the physical functioning section of the SF-36 was observed. Known group validity was established by the ability of the measure to distinguish between subgroups of patients, who differed according to their perceived general health, disease severity (p < 0.001) and whether they were experiencing a flare-up (p < 0.01). The new language version is recommended for use in future research studies, clinical trials and routine practice with Bulgarian RA patients.

[PMID: 32306085 DOI: 10.1007/s00484-020-01911-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2020] [Revised: 03/27/2020] [Accepted: 03/28/2020] [Indexed: 05/19/2023]
Abstract
Osteoarthritis of the knee joint is a public health concern with considerable social impacts and related-costs. Among the treatments available, several benefits of bathing in natural mineral water have been proposed: (1) to identify possible health benefits (in terms of effects on dimensions of pain, functionality, emotional and social aspects, and quality of life) of a 3-week balneotherapy intervention in patients with knee osteoarthritis; (2) to assess the clinical relevance of any benefits detected; and (3) to determine if these effects persist. Participants of this randomized controlled trial (RCT) were 120 patients randomly assigned to (1) an experimental group (3 weeks of balneotherapy consisting of daily whirlpool baths, hydrokinesitherapy sessions, and knee shower/massages) or (2) control group in which no form of treatment apart from their usual analgesia medication was given. Treatment benefits were assessed using the following tools: (1) visual analogue scale (VAS) of pain, (2) Timed Up & Go Test (TUG), (3) WOMAC osteoarthritis questionnaire, and (4) SF 36 health survey questionnaire. In the experimental group, these tests were conducted immediately before treatment, immediately after treatment, and at 3 months of follow-up. Patients assigned to the control group were assessed at the study start and 3 months later. Data processing and statistical analysis were performed using the SPSS (Statistical Package for Social Science) version 22.0. Out of 60 patients in the experimental group, 45 were found to benefit from the treatment intervention in terms of pain relief among other aspects, and also when test scores were compared to those obtained in the control group. Improvements were often clinical relevant and in most patients persisted 3 months after treatment onset.

Abstract
Osteoarthritis (OA) is the most prevalent rheumatic disease and is a leading cause of decreased quality of life (QoL). The OA Quality of Life questionnaire (OAQoL) is an OA-specific patient-reported outcome measures. The aim of this study was to translate and validate the original UK English version of the Osteoarthritis Quality of Life (OAQoL) questionnaire into European Portuguese. The translation of the questionnaire was carried out according to a dual panel methodology (bilingual panel followed by lay panel). This was followed by cognitive debriefing interviews (CDIs) with OA patients to assess comprehension and relevance of the translated questionnaire. Finally, a validation survey was conducted to assess its psychometric properties. The Portuguese OAQoL, a comparator scale (the Nottingham Health Profile-NHP) as well as questions relating to demographic and disease information were administered to OA patients. A sub-sample of patients also completed the Portuguese OAQoL two weeks later, to assess test-retest reliability. The internal consistency, construct validity and known group validity (according to perceived OA severity) of the scale was also assessed. Both the bilingual and lay panels consisted of five individuals and no major difficulties relating to the translation process were identified. A total of ten patients with OA participated in the CDIs. The mean time to complete the questionnaire was 5 min. These interviews revealed that the Portuguese version of the OAQoL was clear, relevant and easy to complete. Finally, 53 OA patients (44 females; mean age of 67.6 years) completed the validation survey. Cronbach's alpha coefficient was 0.87, demonstrating high internal consistency. Test-retest reliability, assessed by Spearman's rank correlation coefficient, was 0.86. Moderate correlations were found with the majority of the NHP sections, providing evidence of construct validity. Significant differences in OAQoL scores were found between patients who differed according to their perceived OA severity, providing evidence of known group validity. The Portuguese version of the OAQoL is a valid and reliable questionnaire that can be used to assess QoL in OA, both in clinical practice and for research purposes.

Validation of the Mini-OAKHQOL for use in patients with osteoarthritis in Spain. Clin Rheumatol 2017; 36:1855-1864. [PMID: 28353088 DOI: 10.1007/s10067-017-3611-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2017] [Revised: 03/08/2017] [Accepted: 03/19/2017] [Indexed: 10/19/2022]
Abstract
The Mini-Osteoarthritis Knee and Hip Quality of Life (Mini-OAKHQOL) questionnaire osteoarthritis is specific to individuals with knee or hip osteoarthritis. The objective of this study was to perform a validation of the Mini-OAKHQOL for use in Spain in terms of its psychometric properties of reliability, validity and responsiveness. Patients with osteoarthritis from the waiting list for a joint replacement completed the OAKHQOL, Short Form 36 Health Survey and Western Ontario and McMaster Universities Osteoarthritis Index. Reliability was assessed in terms of internal consistency and test-retest data, and convergent validity using Spearman's correlation coefficient. Structural validity was investigated by confirmatory factor analysis, and Rasch analysis was used to examine the unidimensionality of the scales. Responsiveness was assessed by calculating effect sizes. Confirmatory factor analysis confirmed the five-factor model, and the results of the Rasch analyses supported the unidimensionality assumption, with infit and outfit statistics. Cronbach's alpha ranged from 0.76 to 0.89 for all except the social dimensions. Statistically significant differences were observed between patients with different degrees of disease severity on all dimensions. There was convergent validity among dimensions expected to be correlated. The OAKHQOL questionnaire showed good responsiveness, with large changes for all dimensions apart from the two social dimensions, which had small effect sizes. Results of the study support the view that the Spanish version of the Mini-OAKHQOL questionnaire is a valid instrument to measure health-related quality of life in patients with osteoarthritis of the lower limb.
