“…Monolingual subjects with different socioeconomic and educational backgrounds are members of the lay panel assessing the appropriateness of the translated version in terms of understandability and comprehensiveness. 25 Despite reports that this translation method has fewer missing items, the higher dedicated time for implementation and the need for combining backward translation prompted us to utilize the forward-backward method. 26 Furthermore, our participants declared that the items were easy to understand, and the total questionnaire had enough question length.…”

Background: Compliance with health-related behaviors is a dilemma among heart failure (HF) patients. The present study aimed to assess the validity and reliability of a Persian translation of the revised heart failure compliance questionnaire (RHFCQ) in Iranian HF sufferers. Methods: This methodological study was performed on outpatient HF individuals referred to a heart clinic in Isfahan, Iran. The forward-backward translation method was used for translation. Twenty subjects were invited to express their opinions on the provided items concerning simplicity and understandability. Twelve experts were invited to rate the items regarding the content validity index (CVI). Cronbach’s α was used to evaluate internal consistency. The patients were asked to complete the questionnaire for the second time after 2 weeks to investigate test-retest reliability using the intraclass correlation coefficient (ICC). Results: There were no obvious difficulties during the translation and assessment of the simplicity and comprehensiveness of the questionnaire items. The CVI of the items ranged from 0.833 to 1.000. Totally, 150 patients (age: 64.60±15.00 y, males: 58.0%) filled in the questionnaire twice with no missing data. The highest and lowest compliance rates were attributed to alcohol and exercise domains, respectively (83.00±7.70% and 45.55±12.00%, respectively). Cronbach’s α was 0.629. After the omission of 3 items related to smoking and alcohol cessation, Cronbach’s α rose to 0.655. The ICC showed an acceptable value of 0.576 (95% CI, 0.462 to 0.673). Conclusion: The modified Persian RHFCQ is a simple and meaningful tool with acceptable moderate reliability and good validity for assessing compliance in Iranian HF patients.

“…The first panel conducts the initial translation of the questionnaire, while the second group, consisting of monolingual individuals, is asked to provide feedback on the clarity and comprehensibility of the translated version. 27 , 28 It has been reported that the dual-panel method has fewer missing items during the translation process. However, this method is more time-consuming and might be associated with difficulties to perform thoroughly.…”

“… 29 Moreover, it has been recommended that the translated draft of the questionnaire is needed to be combined with backward translation. 27 , 30 Therefore, we decided to use the common forward-backward translation method. Also, our findings revealed that there was not any missing item during translation of the original LVD-36 questionnaire.…”

Background: The left ventricular dysfunction 36 (LVD-36) questionnaire is considered to be a tool to assess the impact of left ventricle impairment on patients’ daily life. This methodological study was aimed to translate and assess the validity and reliability of the Persian draft of the LVD-36 questionnaire among Iranian heart failure (HF) patients. Methods: We recruited stable HF patients who referred to an outpatient heart clinic in Isfahan, Iran. The LVD-36 questionnaire was translated using the forward-backward method. Twenty HF patients were recruited for content validity assessment and were asked to express their opinions about the comprehensibility and meaningfulness of each item. We invited 14 experts to assess validity through content validity index (CVI) and content validity ratio (CVR). Reliability was assessed by Cronbach’s alpha and intraclass correlation coefficient (ICC), with the latter evaluated after invitation of the participants to complete the questionnaire for the second time. Results: The translation process was performed uneventfully without any significant alterations. A total of 150 HF patients were recruited to assess the reliability of the questionnaire in this study (age: 64.6±16 years, males: 58.6%). All items had acceptable CVI and CVR, ranging 0.85–1.00 and 0.57–1.00, respectively. Cronbach’s alpha was 0.971. All participants completed the questionnaire for the second time with no missing data. Test-retest reliability revealed an excellent ICC value of 0.981 (95% CI: 0.977–0.985). Conclusion: The Persian version of the LVD-36 questionnaire is a simple, valid and reliable tool for evaluating the impact of left ventricle impairment on the well-being of Iranian HF patients.

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.
