This study aimed to translate, culturally adapt, and validate \"The Nutrition for Sport Knowledge Questionnaire (NSKQ)\" for Brazilian athletes. The NSKQ is an Australian instrument composed of 87 questions divided into six subsections (weight control, macronutrients, micronutrients, sports nutrition, supplementation, and alcohol) designed to assess the nutritional knowledge (NK) of athletes. The translation process followed the recommendations of the World Health Organization for translating and adapting instruments. Semantic validation involved a panel of specialists (n = 21), followed by an assessment performed by a group of adult Brazilian athletes from various sports (n = 17). The reproducibility and internal consistency of the questionnaire were evaluated via a test-retest approach in a sample of adult Brazilian athletes (n = 29) from diverse sports, who completed the Brazilian version of the NSKQ (NSKQ-BR). Overall, the NSKQ-BR presented good internal consistency (α = 0.95) and reproducibility (intraclass correlation coefficient (ICC) = 0.85). The factors \"sports nutrition\" and \"alcohol\" showed moderate reproducibility (ICC = 0.74 (0.46-0.88) and ICC = 0.68 (0.33-0.85), respectively). Most athletes (n = 17; 58.6%) presented a medium NK score (50-65%). The NSKQ-BR is available to evaluate the NK levels of Brazilian athletes. The NSKQ-BR presented high internal consistency and reproducibility, validating its applicability among adult athletes across diverse sports.

BACKGROUND: Occupational safety and health are of utmost importance in the palm oil industry, particularly in Malaysia where palm oil plantation workers face various hazards. This study aimed to translate and validate a risk perception questionnaire specifically designed to assess the perceptions of safety and health risks among palm oil plantation workers in Terengganu, Malaysia.
METHODS: The original risk perception questionnaire, consisting of 22 items, was translated into the local language and culturally adapted. The translation process involved forward translation, expert panel discussions, and back translation to ensure linguistic equivalence. The translated questionnaire was then administered to a sample of palm oil plantation workers in Terengganu, Malaysia, for validation purposes. Confirmatory factor analysis (CFA) was conducted to assess the model fitness of the questionnaire, and Cronbach\'s Alpha coefficient was calculated to determine the internal consistency reliability of the final model.
RESULTS: The translated risk perception questionnaire demonstrated good model fitness as indicated by CFA results (X2=224, df=79, p-value<0.0001, root mean square error of approximation (RMSEA)=0.07, goodness of fit index (GFI)=0.929, comparative fit index (CFI)=0.902). The questionnaire\'s final version has one factor comprising 13 items, selected based on factor loadings and theoretical relevance. The internal consistency reliability of the 13-item questionnaire was satisfactory, with a Cronbach\'s Alpha coefficient of α=0.77.
CONCLUSIONS: The 13-item risk perception questionnaire demonstrated a good model fit and acceptable internal consistency reliability. It shows that the questionnaire is a valid and reliable tool to evaluate the level of risk perception on safety and health among palm oil plantation workers in Malaysia.

Introduction Dysphagia is one of the general symptoms encountered in clinical practice. The impact of dysphagia can be devastating to a patient\'s physical condition and quality of life (QOL). To evaluate the QOL of patients with dysphagia there are numerous self-reported questionnaires. The most commonly used one such questionnaire is the Swallowing Quality-of-Life Questionnaire (SWAL-QOL). However, it is not concise and is incomplete as it does not address all the aspects of dysphagia. To overcome this, the Dysphagia Handicap Index (DHI) was developed. It focuses on the functional and emotional aspects in addition to the physical aspects of dysphagia. Objective To develop a Tamil version of the DHI (DHI-T) and assess its reliability, cultural adaptability and validity. Materials and method This cross-sectional study was conducted from May 2021 to December 2022 on 140 participants consisting of 70 dysphagia patients and 70 healthy individuals. Results The reliability and validity of the DHI-T were good with a high correlation between DHI-T and self-perceived severity scales of dysphagia. The mean total score in the Dysphagia group was 59.77 with the mean physical, functional and emotional scores being 23.86, 17.46 and 18.46 respectively. These scores were less compared to the Healthy group (p-value <0.01). Conclusion This study shows that DHI-T can be used as a reliable and valid tool to grade and study the different domains of dysphagia in our study population. Among the various causes of dysphagia studied in our population, it was noted that coronavirus disease 2019 (COVID-19)-related dysphagia patients had higher mean score in the emotional domain. To the best of our knowledge, the DHI scores for COVID-19-related dysphagia have not been done before. As the application of DHI in routine clinical practice and research is increasing, we believe this DHI-T can be of aid to Tamil-speaking patients.

Objectives This study aimed to translate the Dyspnea Index (DI) questionnaire into the Arabic language and determine whether this version is valid and reliable for Arabic-speaking patients with upper airway-related dyspnea. Methods A cross-sectional study was conducted at the King Saud University Medical City otolaryngology clinics in Riyadh, Saudi Arabia. The DI questionnaire was translated into Arabic and then back-translated into the English language. Inclusion criteria were preoperative patients presenting to the otolaryngology clinic with upper airway-related dyspnea between November and December 2020. The results of internal consistency and factor analysis among the items were compared to the original DI development results to assess the reliability of the questionnaire. Results Among a total of 57 recruited patients, 50 questionnaires were completed with an 88% response rate. The mean age of the included patients was 38 ±14 years. Women constituted 58% of the patients. The most common diagnosis was subglottic stenosis (72%). Principle component extraction in factor analysis revealed a single underlying factor for all the questions. Factor loading ranged from 0.69 to 0.85. Reliability statistics showed a high value of internal consistency among the items. The mean inter-item correlation was 0.58. Conclusion Based on our findings, the Arabic version of the DI questionnaire is a reliable instrument for evaluating upper airway dyspnea.

Background This study aimed to translate the Bladder Cancer Index (BCI) questionnaire to Urdu and validate it to assess the quality of life of patients with bladder cancer. Material and methods After forward and backward translation of the BCI questionnaire into Urdu, content validity was calculated using the content validity index (CVI) based on input from five health experts regarding the clarity and relevance of the questionnaire. Construct validity was measured by comparing the inter-scale domains and subdomains of BCI and by comparing BCI with Short Form 36 (SF-36) using correlations. For assessment of reliability, Cronbach\'s alpha was calculated to measure internal consistency and for test-retest reliability, the questionnaire was re-administered four weeks later and the correlation of responses at baseline and at a four-week time point was evaluated. Results The questionnaire has good content validity for clarity (0.91) and relevance (0.87). The construct validity of BCI was also adequately displayed by moderate to high correlation between different subdomains of BCI (Pearson\'s r: urinary - 0.62, bowel - 0.78, sexual function - 0.43) and low to moderate correlation between responses of BCI compared with SF-36 (Pearson\'s r mostly >0.45). Test-retest reliability was excellent (Pearson\'s r 0.90-0.98), and there was good internal consistency (Cronbach\'s alpha 0.79-0.92) in the different domains of the questionnaire. Conclusion The Urdu-translated BCI is a valid and reliable tool to measure the impact of bladder cancer on the quality of life of patients.

OBJECTIVE: The present study aimed to investigate the preliminary effects of collaborative learning and simulation on readiness to engage in and attitudes toward future interprofessional learning activities. We translated into Norwegian and validated the original Readiness for Interprofessional Learning Scale (RIPLS) (part 1) to measure the efficacy and feasibility of a structured collaborative learning activity (part 2).
METHODS: Undergraduate social and health care professional students from five Norwegian universities (n = 307) participated in the validation stage of this study (part 1). A Norwegian version of the RIPLS was developed using forward and backward translation. An expert panel discussed discrepancies between the translations and professional concepts. We planned to conduct a principal component analysis to evaluate the structure, reliability, and internal consistency of the Norwegian version of the RIPLS, after investigating the skewness, kurtosis, and range of items included. One hundred fifty students participated in collaborative learning activities; 72 (48%) of these individuals answered the translated RIPLS questionnaire.
RESULTS: We found a substantial ceiling effect in the majority of items in the RIPLS, making it difficult to use the instrument as a measure of change. We evaluated the efficacy and feasibility of the collaborative activities based on the changes in the single items that had sufficient univariate normality and ultimately confirmed positive changes in two of these items.
CONCLUSIONS: Norwegian students appear ready for interprofessional learning; however, due to significant ceiling effects, the majority of items in the RIPLS no longer seem suitable for measuring and evaluating the effects of interprofessional learning (part 1). Single-item analysis revealed a potential effect of collaborative learning (part 2). A new questionnaire is needed where readiness is instead understood as self-efficacy in areas such as role awareness and interprofessional communication. Researchers should be aware that even previously validated questionnaires may lose their applicability over time and require revision. Demands for interprofessional learning and practice are continuously evolving, and evaluation methods should be adjusted accordingly.

To cross-culturally translate and validate the Chinese versions of the Oxford Knee Score (OKS) and the Activity and Participation Questionnaire (APQ) in patients with end-stage knee osteoarthritis who are also candidates for knee replacement.
The Chinese version of the OKS and APQ was completed by standard forward-backward translation and adaption. The feasibility was validated by a pretest in 30 patients. The final version together with the Short Form-36 (SF-36), EQ-5D, and EQ visual analog scale were assessed in 150 patients, and the OKS and APQ were repeated in 30 patients after a 2-week interval. The psychometric properties of the OKS and APQ were evaluated for test-retest reliability using intraclass correlation coefficients (ICCs), internal consistency using Cronbach\'s α, and construct validity using Spearman\'s correlation analysis.
All patients were able to understand and complete both the OKS and APQ without difficulty (i.e. no missing data). The ICCs were 0.959 for the OKS, 0.956 for the APQ for total scores, and >0.7 for each item. Cronbach\'s α was greater than 0.7, and the corrected item-total correlation was greater than 0.4 for each item of both questionnaires. The OKS and APQ showed better correlations with questions from the pain and function domains than with those from the mental status domains of the SF-36 and EQ-5D. No floor or ceiling effect was identified in either questionnaire.
The Chinese versions of the OKS and APQ are easy to understand and complete and showed good reliability and validity. They can be used to assess patient-reported outcomes after undergoing knee replacement in mainland China.

BACKGROUND: Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) has been translated from English into several languages. Currently, there is no validated translation of FACT-BMT in Arabic. Here, we are reporting the first Arabic translation and validation of the FACT-BMT.
METHODS: The study was approved by the Institutional Research Advisory Council. The Arabic translation followed the standard Functional Assessment of Chronic Illness Therapy (FACIT.org) translation methodology (with permission). Arabic FACT-BMT (50- items) was statistically validated. Cronbach\'s alpha for internal consistency, Spearman\'s rank correlation coefficients method for Inter-scale correlations and Principal Component Analysis for factorial construct validity was used.
RESULTS: One hundred and eight consecutive relapsed /refractory lymphoma patients who underwent high dose chemotherapy and autologous stem cell transplant were enrolled. There were 68 males (63%) and 40 females (37%) with a median age of 29 years (range 14-62). After Arabic questionnaire pre-testing (Cronbach\'s alpha 0.744), the study included 108 patients. Cronbach\'s alpha for the entire FACT-BMT indicated an excellent internal consistency (0.90); range (0.67 to 0.91). Cronbach\'s alpha for sub-groups of social (0.78), emotional (0.67) and functional wellbeing was (0.88). Cronbach\'s alpha for bone marrow transplant (0.81), FACT-General (0.89), and FACT- Trial Outcome Index (TOI); (0.91) also revealed excellent internal consistency. Patients had high scores in all domains of quality of life, indicating that most patients were leading a normal life. This translation of FACT-BMT in Arabic was reviewed and approved for submission by the FACIT.org.
CONCLUSIONS: Our data reports the first translated, validated and approved Arabic version of FACT-BMT. This will help large numbers of Arabic speaking patients undergoing stem cell/bone marrow transplantation, across the globe.

OBJECTIVE: Youth suicide rates are rising worldwide, including Sri Lanka, where 46.5/100,000 among 15-19yrs was reported in 1986. Identifying high risk adolescents is vital. Dearth of trained professionals, demands an instrument utilizable by non-psychiatrists. Such was not available in Sinhalese. Adolescent Suicide Assessment Protocol (ASAP-20) and its\' manual was translated and validated to Sri Lankan adolescents.
METHODS: A validation study. Forward/back translations followed by cultural adaptation. Face validity, operational equivalence were assessed. Panel of Psychiatrists assessed semantics, conceptual, content/construct validity using external criticism. Final Sinhalese version was applied to 100 Sinhalese speaking 10-19yr olds referred to Psychiatry units of two Teaching Hospitals following a suicide attempt or with suicidal ideation (cases) excluding psychotic disorder, acute emergencies or special needs and compared with same aged adolescents on treatment for respiratory problems as controls. Discriminant ability was calculated using area under the Receiver Operating Curve (AUC). Reliability was calculated using Cronbach\'s alpha.
RESULTS: Sinhalese version showed satisfactory face/contents/construct validity and operational equivalence. Median suicide risk score was 18 and mean 17.99 (SD = 7.56) for cases, median = 4 and mean = 4.86 (SD = 2.41) for controls. AUC was 0.969 (SE = 0.11), indicating a high ability to discriminate moderate/high from low suicidal risk. Cut off value, 8.5 was lower than original tool at a sensitivity of 91% and a specificity of 91%. Cronbach\'s alpha was 0.811 indicating high reliability and consistency.
CONCLUSIONS: Sinhalese version of ASAP-20 is a successful screening instrument to detect high suicide risk among adolescents in clinical and non clinical settings.

The Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-O) and the Oslo Sports Trauma Research Centre questionnaire on Health Problems (The OSTRC-H) make it possible to monitor illness and injury at regular intervals capturing prevalence and incidence of acute injury, overuse injury, and illnesses. The aim of this study was to translate, culturally adapt, and establish the face validity of the OSTRC-O and the OSTRC-H into a Danish context (DK) through cognitive interviews and the assessment of test-retest reliability. The OSTRC-O.DK was distributed to 57 heterogenous respondents; response rate was 89%. The OSTRC-H was distributed to 58 heterogenous respondents; response rate was 86%. No major disagreements were observed between the original and translated versions of the questionnaires. The OSTRC-O had high internal consistency (Cronbach\'s alpha 0.80-0.93). The primary reliability analyses including all participants, showed reliability ICC: 0.62 (95% CI: 0.42-0.77. The secondary reliability analyses that only included subjects who did not change injury region from the test to the retest showed an ICC of 0.86 (95% CI: 0.77-0.92).The questionnaires were found to be valid, reliable, and acceptable for use in a Danish population.
