Project description:BackgroundThis study appraises the psychometrics properties of the Inflammatory bowel disease-fatigue (IBD-F) Persian version questionnaire.MethodsThe original IBD-F questionnaire was translated into the Persian version in a standard forward-back manner. The validation was performed through the face, content, and construct validity. Fifteen experts scored each item's necessity on an ordinal Likert scale of three; then, the content validity ratio was calculated using the Lawshe formula. Eight judges from pre-defined panel rated each item on an ordinal 4-point Likert scale concerning its relevancy, clarity, and simplicity for individual-CVI calculation. The mean individual-CVI was considered as the Scale-CVI for each domain. Twenty lay experts (selected from the target population) were asked to express their opinion on each item's importance by scoring on a 5-point Likert scale; subsequently, face validity was determined by the impact score formula. The questions that had minimum values of CVR, CVI, and impact score were retained in the final version of the questionnaire for reliability evaluation. Construct validity was evaluated via Confirmatory Factor Analysis. Internal consistency and test-retest reliability were checked using Cronbach's α and intraclass correlation coefficients (ICC). Fifty-four patients recruited based on inclusion and exclusion criteria to participate in the reliability analysis.ResultsAll the questions received the qualified values of CVR (exceeding 0.49 points) and impact score (more than 1.5 points) and were retained in the questionnaire; however, revisions were made for questions with a CVI 0.7-0.9 for clarity and simplicity. The result demonstrated relative goodness CFA and proper internal consistency, as Cronbach's α coefficient was 0.964 for the test (0.845 and 0.963 for the first and second part of the questionnaire, respectively (and 0.888 for the re-test (0.793 and 0.876 for the first and second section of the questionnaire, respectively). The ICC values between test and re-test for the first and second part and the whole questionnaire were obtained as 0.904, 0.922, and 0.921, respectively.ConclusionThe Persian version of the IBD-F questionnaire was valid and reliable; thus, an appropriate scale was deemed to measure fatigue (severity, frequency, and impact on daily activities).

Project description:BackgroundThe 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.MethodsWe 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.ResultsThe 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).ConclusionThe 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.

Project description:ObjectiveTo translate and cross-culturally adapt into Italian the YQOL-DHH (Youth Quality of Life Instrument-Deaf and Hard of Hearing Module), an instrument to evaluate the health-related quality of life in young deaf people. It could be useful for professionals, teachers, and parents to take care of deaf adolescents' needs.Study designForward-backward translation, cross-cultural adaptation, and cognitive debriefing.SettingThe cognitive debriefing was performed online with professionals and during clinical practice with deaf adolescents.MethodsA methodological study was conducted according to the guidelines provided by the development team. The study consisted of a forward-backward translation and a cross-cultural adaptation. After the original authors' confirmation, a cognitive debriefing was conducted with 30 professionals who work with deaf young people and with 10 deaf adolescents aged 11 to 18 years.ResultsFor the linguistic translation and cross-cultural adaptation, some variations to the original instrument were made to obtain equivalence, such as the expression "deaf or hard of hearing" translated only with the Italian word "sordo." During the cognitive debriefing, the clarity and comprehensibility of the items were reported by professionals and deaf adolescents. Eventually, the authors approved the final version.ConclusionThe YQOL-DHH was translated and culturally adapted into Italian. The translated items were pertinent to the Italian culture and equivalent to the original ones. A validation study is suggested to make the instrument feasible for use in different clinical or educational contexts. In addition, to guarantee accessibility and autonomy for young deaf signers, Italian Sign Language translation of the questionnaire is suggested.

Project description:Study designCross-sectional study.PurposeTo translate and culturally adapt the original English version of the 24-item Early-Onset Scoliosis Questionnaire (EOSQ-24) to the Persian language as well as assess its reliability and validity.Overview of literatureEarly-onset scoliosis (EOS) patients with progressive curves require active treatments, such as serial elongation- derotation-flexion casting, bracing, and surgery, which are stressful and expensive. In order to evaluate the impact of EOS and its treatment strategies, it is important to consider the patients and their parents' quality of life as the clinical and radiological parameters. The EOSQ-24 is a parent-based measure that evaluates the health-related quality of life of patients with EOS and their caregivers/parents. Similar to other widely used questionnaires, EOSQ-24 needs to be translated into other languages to make it usable in populations from different cultures and societies.MethodsWe evaluated the translation and back translation of the EOSQ-24 and made the required revisions as per the analysis performed by the expert committee and an international guideline to adapt it for use in this study. Thereafter, we recruited 100 EOS patients in order to evaluate its reliability and validity. The reliability was assessed with internal consistency. Convergent validity was assessed by comparing the scores of the EOSQ-24 and the 22-item Scoliosis Research Society Questionnaire (SRS-22r). Finally, the known groups validity was assessed as per patient's sex, curve magnitude, and treatment type.ResultsThe Persian EOSQ-24 demonstrated very good internal consistency (Cronbach's α=0.88). All the items had an acceptable corrected item-total correlation (>0.3). Further, the EOSQ-24 and the SRS-22r scores (p <0.001) were significantly correlated. The EOSQ-24 could discriminate patients with different curve magnitudes.ConclusionsThe Persian EOSQ-24 can serve as a disease-specific instrument with strong validity and reliability in the evaluation of EOS patients. Its applicability in other Persian-speaking countries and regions of the world needs to be investigated further.

Project description:IntroductionThe effective treatment of anal fistulas almost always requires surgical intervention, which could be accompanied by post-operative complications, and affect the quality of life of patients. This study aimed to cross-culturally adapt the Persian version of the Quality of Life in patients with Anal Fistula questionnaire and evaluate its validity and reliability.Materials and methodsSixty patients with a mean age of 44 years ranging from 21 to 72 years entered the study. Forty-seven participants were men, and thirteen were women. After performing a scientific translation of the questionnaire based on Beaton's guidelines for cross-cultural adaptation and after extensive reviews by experts and specialists, the final version of the questionnaire was obtained. Then, 60 questionnaires (100%) were filled out by the participants (n = 60) and retrieved during a 7 to 21-day period. Data were collected and analyzed. Finally, according to the obtained data, the validity and reliability of the questionnaire were calculated.ResultsCross-cultural adaptation of the translated questionnaire was verified by the expert committee. The results showed perfect internal consistency (Cronbach alpha = 0.842), and external consistency (intraclass correlation coefficient = 0.800; P<0.001). Spearman correlation coefficient between test and retest was reported to be 0.980 (P-value <0.01), confirming the temporal stability of the translated questionnaire. The interrater reliability based on Cohen's kappa coefficient also demonstrated a perfect degree of agreement between two peer variables (Kappa = 0.889; P<0.001).ConclusionThe Persian translation of the Quality of Life in patients with the Anal Fistula questionnaire was proven to be valid and reliable for the evaluation of the QoL of patients with anal fistula.

Project description:BackgroundThe Spanish version of the Computer Vision Syndrome Questionnaire (CVS-Q©) is a validated instrument, with good psychometric properties, to measure Computer Vision Syndrome (CVS) in workers using Video Display Terminals (VDTs). To date, there are no known valid instruments in Chinese for the assessment of CVS despite the high exposure to VDTs at work that this population presents. For this, the purpose of this study is to translate and cross-culturally adapt the CVS-Q© into Chinese.MethodsA study with five consecutive stages: direct translation, synthesis of translations, back translation, consolidation by a committee of experts, and pre-test. During the pre-test, a cross-sectional pilot study was conducted on VDT users (n = 44) who completed the Chinese version of the questionnaire plus an ad hoc post-test to assess the comprehensibility of the scale and to verify aspects of its applicability and feasibility. Data concerning sociodemographic information, general and ocular health, use of optical correction and varying exposure to VDTs was also collected.ResultsThe entire sample considered the Chinese version of the CVS-Q© simple, clear, and easy to understand and 95.5% also found it easy to complete. 88.7% considered that the scale did not need any improvement. The final version of the Chinese scale to measure CVS was obtained (the CVS-Q CN©). The mean age of participants was 31.3 ± 9.8 years, 47.6% were women, and 57.1% used VDTs to work for more than 8 h/day.ConclusionsThe CVS-Q CN© can be considered an easy tool to assess CVS in workers exposed to digital devices in China. This version would facilitate research, its use in clinical practice, and the prevention of occupational hazards in the workplace.

Project description:PurposeTo perform a cross-cultural adaptation and validation of the Brazilian-Portuguese versions of the Brace Questionnaire in adolescent idiopathic scoliosis.MethodsA forward-backward translation process was employed to produce a Brazilian Portuguese version of the Brace Questionnaire, followed by comprehensive cross-cultural adaptation stages. The measurements of internal consistency and test-retest reliability were assessed by Cronbach's a and intraclass correlation coefficient (ICC), respectively. The Pearson's correlation coefficient was used to analyze the concurrent validity by comparison with the Scoliosis Research Society-22r questionnaire.ResultsA total of 84 scoliosis patients (age 13.4 ± 2.0 years, thoracic Cobb angle 33.3° ± 13.8°, and lumbar Cobb angle 29.8° ± 14.3°) were included. The Brace Questionnaire showed excellent internal consistency (Cronbach α = 0.93) and moderate reliability (ICC = 0.86). The correlations between the Brace Questionnaire and Scoliosis Research Society-22 were r = 0.66; p = 0.011. In addition, it was found that the Brazilian version of the Brace Questionnaire does not have ceiling and floor effects.ConclusionsThe Brazilian-Portuguese adaptation of the brace questionnaire shows excellent reliability and can be a valid tool for psychometric assessment in adolescent idiopathic scoliosis.

Project description:PurposeTo translate, cross-culturally adapt and validate the Computer Vision Syndrome Questionnaire (CVS-Q©) into Persian.MethodsThis study was carried out in 2 phases: (1) the CVS-Q© was translated and cross-culturally adapted into Persian and (2) the validity and reliability of CVS-Q FA© were assessed in a cross-sectional validation study. An expert committee composed of 15 optometrists evaluated content validity (item-level (I-CVI) and scale-level (S-CVI) content validity index were calculated). A pretest was performed (n = 20 participants) to verify the comprehensibility of the questionnaire. A total of 102 computer users completed the final questionnaire. Criterion validity and diagnostic performance of the CVS-Q FA© were assessed by calculating sensitivity, specificity and receiver characteristic operator curve. Cronbach's alpha was calculated for the assessment of internal consistency and 46 participants refilled the questionnaire for the second time and the interclass correlation coefficient (ICC) and Cohen's kappa (κ) were evaluated for test-retest reliability.ResultsThe translation and cross-cultural adaptation process was performed successfully according to accepted scientific recommendations without any major difficulties. The I-CVI was above 0.80 for all items (symptoms) except item 15 (feeling that sight is worsening) and the S-CVI was 0.92. The CVS-Q FA© showed good sensitivity (81.1%) and acceptable specificity (69.2%). Also, it achieved good internal consistency (Cronbach's alpha = 0.80) and test-retest reliability (ICC = 0.81 and κ = 0.65).ConclusionThe CVS-Q FA© was successfully translated, cross-culturally adapted, and validated into Persian. This study provides a valid and reliable tool for the assessment of computer vision syndrome among the Iranian working population.

Project description:BackgroundThe Anterior Cruciate Ligament-Quality of Life (ACL-QOL) questionnaire is a patient-reported outcome measure used to assess the effect of an anterior cruciate ligament (ACL) injury on the lives of patients. It was originally written in English, which may affect its use when completed by nonnative English speakers.PurposeTo translate and adapt the ACL-QOL to Spanish and provide evidence of its psychometric properties.Study designCohort study (diagnosis); Level of evidence, 2.MethodsA total of 183 patients with an ACL injury from 4 Catalan hospitals were included: 99 patients who had undergone ACL reconstruction (ACLR) completed the Spanish version of the ACL-QOL (ACL-QOL-Sp) twice (mean interval, 15.2 days) in 2 weeks for test-retest reliability, and 84 patients completed the ACL-QOL-Sp, the Lysholm knee scoring scale, the Knee injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Scale, and the 12-item Short Form Health Survey (SF-12) before and at 4 and 9 months after ACLR to assess responsiveness. The association between the ACL-QOL-Sp and the other outcome measures was evaluated with the Spearman correlation coefficient.ResultsThe ACL-QOL-Sp showed good internal consistency (Cronbach alpha = 0.96) and test-retest reliability (intraclass correlation coefficient = 0.97). The standard error of measurement was 3.6, also suggesting the precision of measurements. The smallest detectable change was 9.98 in 94% of patients. No association was found between the ACL-QOL-Sp score and the Tegner score or SF-12 mental component summary score; however, a moderate correlation was found with the overall KOOS score (r = -0.545), Lysholm score (r = 0.509), and SF-12 physical component summary score (r = 0.607). The correlation ranged from weak for the KOOS-Symptoms subscore (r = -0.290) to moderate for the KOOS-Quality of Life subscore (r = -0.698). No ceiling or floor effects were observed. The ACL-QOL-Sp showed a moderate effect size (0.73) at 4 months but a large effect size (1.70) at 9 months.ConclusionThe ACL-QOL-Sp showed adequate internal consistency, test-retest reliability, and responsiveness in evaluating quality of life after ACLR in Spanish-speaking patients.
