Translation Of Questionnaire Research Articles

Showcasing the usefulness of web probing: Do subtle variations in questionnaire translation lead to different survey responding?

It is generally taken for granted that comparability in comparative research hinges, among others, on the quality of questionnaire translations. However, what do slight differences in translation mean for respondents’ answers? In this article, we look at a combination of quantitative evidence from split-ballot experiments and qualitative evidence from additional probing questions for three items that were translated according to different translation methods, resulting in different translations, e.g., for “our national way of life.” Two of the three items do not show any quantitative differences between translation versions when implemented in split-ballot experiments. However, using open-ended probing questions we delved deeper into the effects of different translation versions. This allowed us to show that different translations do indeed change respondent understanding. We suggest mechanisms that may lead to different translations (not) having an impact on the data, and we also try to align the results to the notion of equivalence/comparability in translation. Ultimately, we showcase the usefulness of web probing for exploring different translation understandings.

Adaptation and validation of the Spanish version of NOSE-Perf questionnaire for septal perforations

Background and objectiveSeptal perforation (SP) cause heterogeneous symptoms depending on the anatomical location, highlighting scabs, nasal obstruction and/or epistaxis. The use of questionnaires to determine the quality of life in different pathologies is increasing in sinonasal pathologies and in patients with SP the NOSE-Perf questionnaire was constructed, currently validated in English. The aim of this study is the translation, cross-cultural adaptation, and validation of the NOSE-Perf questionnaire into Spanish. Material and methodsProspective single-centre study of 81 patients (38 with SP and 43 controls), visited in the rhinology section of a tertiary hospital. Adaptation and translation NOSE-Perf into Spanish and validation using the NOSE and NOSE-Perf questionnaire in Spanish. ResultsSignificant differences were found in the mean NOSE-Perf score and in the mean NOSE score (IC95% = 21.2–26.9; p < 0.001 and IC95% = 53.8–70.5; p < 0.001) between SP group and control group. Pearson's correlation between the two questionnaires NOSE-Perf and NOSE in the SP group was 0.74 (95% CI = 0.56−0.86; p < 0.001). In the control group it was r = 0.85 (95%CI = 0.73−0.91; p < 0.001). Cronbach's alpha coefficient of the NOSE-Perf was 0.95 (IC 95% = 0.93−0.96) for internal consistency. The reliability evaluation was carried out by test-retest, and a strong Pearson correlation was obtained between the questionnaires r = 0.94 (CI95% = 0.85−0.97; p < 0.001) and r = 0.89 (95%CI = 0.77−0.95; p < 0.001). ConclusionsThe Spanish version of the NOSE-Perf is as reliable and valid as the English version, which makes it possible to assess the impact on quality of life that it causes in patients with perforations in the Spanish-speaking population.

Translation and Validation of the Premenstrual Assessment Form-Short Form Questionnaire in Hungarian.

Premenstrual symptoms, including premenstrual syndrome and its more severe form premenstrual dysphoric disorder, are a set of somatic and psychological symptoms that occur during the luteal phase of the menstrual cycle. Our research aimed to adapt the Hungarian version of the Premenstrual Assessment Form-Short Form (PAF-SF), a questionnaire suitable for assessing premenstrual symptoms, and to examine its reliability, validity, and applicability. The questionnaire was validated according to Beaton's six-step guidelines. Our sample consisted of 198 menstruating women, 50 of whom completed the instrument for a second time to assess reliability. Descriptive statistics were calculated presenting mean (standard deviation), the internal consistency was measured by Cronbach's alpha value, the test-retest reliability using intraclass correlation coefficients, Spearman rank correlation was applied to test the criterion validity of the questionnaire, and discriminant validity was examined using the independent-sample t test using IBM SPSS 28.0 software. The structural validity was evaluated by confirmatory factor analysis (CFA) using IBM AMOS 29.0 software. The level of significance was set at p < 0.05. Our sample (average age 25.37 ± 4.80 years) scored 28.08 ± 9.49 points out of the maximum 60 points when filling out the PAF-SF questionnaire. The result of Cronbach's alpha calculation, which supports the reliability of the questionnaire, was 0.845. During the CFA, the three-factor structure (Affect, Water Retention, and Pain) was supported (root mean-square error approximation [RMSEA] = 0.054; Tucker-Lewis Index = 0.965; Comparative Fit Index = 0.976; χ2 = 48.642; df = 31; p = 0.023; χ2/df = 1.569). The PAF-SF questionnaire proved to be a reliable measuring tool for assessing premenstrual symptoms among women of reproductive age.

Urdu Translation and Cross-Cultural Adaptation of Canadian Assessment of Physical Literacy-2 (CAPL-2) Questionnaires: A Reliability Analysis in Pakistani Children

Background. Physical literacy is vital for addressing children’s health issues such as childhood obesity, physical inactivity, and sedentary behavior. However, there is a lack of research on PL assessment in Pakistan. This study is aimed at translating and cross-culturally adapting the Canadian Assessment of Physical Literacy-2 (CAPL-2) tool and establishing its validity and reliability in the Pakistani population. Methods. The CAPL-2 was translated to Urdu employing the translation and back translation method. A cross-sectional study involving 350 school children (8-12 years) from Multan, South Punjab, evaluated the CAPL-2U version’s reliability. Results. Expert consensus and pilot testing successfully achieved translation, cross-cultural adaptation, face and content validity. The CAPL-2U demonstrated excellent reliability and internal consistency across the domains. Specifically, daily behavior domain had an internal consistency of α=0.964 and test-retest reliability of ICC=0.930. Knowledge and understanding domain showed internal consistency ranging from α=0.906 to 0.986 and test-retest reliability of ICC=0.827 to 0.986. The motivation and confidence domain had an internal consistency of α=0.923 to 0.997 and test-retest reliability of ICC=0.857 to 0.993. The correlation between test-retest results for knowledge and understanding and motivation and confidence domains was r=0.318 to 0.973. However, two items in the motivation and confidence domain showed discrepancies in test-retest outcomes. Conclusion. The study confirms the successful translation and adaptation of the CAPL-2 questionnaire for use in Urdu and Pakistani contexts. The findings endorse the tool’s reliability and suitability for assessing physical literacy in Pakistan’s children aged 8-12.

The Chinese translation and cross-cultural adaptation of PRISMA-7 questionnaire: an observational study to establish the accuracy, reliability and validity

BackgroundFrailty is a health condition linked to adverse health outcomes and lower life quality. The PRISMA-7, a 7-item questionnaire from the Program on Research for Integrating Services for the Maintenance of Autonomy (PRISMA), is a validated case-finding tool for frailty with good sensitivity and specificity. This study aimed to translate, culturally adapt, and validate the PRISMA-7 questionnaire for Chinese use.MethodsA prospective observational study with convenience sampling recruited bilingual adults aged 65 and over living in the community. The Functional Autonomy Measurement System (SMAF) was the gold standard benchmark. The English PRISMA-7 questionnaire was culturally adapted to Chinese using forward and backward translation. Intra- and inter-rater reliability were determined using the intraclass correlation coefficient (ICC). Face, content and criterion validity were determined. The Receiver Operator characteristic (ROC) curve determined the optimal cut-off score.ResultsOne-hundred-twenty participants (55 females and 65 males) were recruited. The Chinese PRISMA-7 questionnaire had excellent intra-rater and inter-rater reliability (ICC = 1.000). The rigorous forward and backward translation established the face and content validity. The moderately high correlations between the English PRISMA-7 with SMAF (r = − 0.655, p < 0.001) and Chinese PRISMA-7 with SMAF (r = − 0.653, p < 0.001) pairs established the criterion validity. An optimal cut-off score of three “Yes” responses was reported with 100% sensitivity and 85.3% specificity.ConclusionThis translation, cross-cultural adaptation, and validation study established the Chinese PRISMA-7 questionnaire. The preliminary results suggest adequate diagnostic test accuracy for frailty screening among the Chinese-literate community.

Electronic adaptation and danish cross-cultural translation of PEmb-QoL and VEINES-QoL/Sym for patients with venous thromboembolism.

Most patient-reported outcome (PROs) used in thrombosis research and clinical practice are delivered using technology like online questionnaires. However, only few have undergone formal electronic adaptation from paper to digital versions, threatening the validity and reliability of the PROs. The present study aimed to perform an electronic adaption and cross-cultural translation of two PROs measuring health-related quality of life in a Danish cohort of patients with venous thrombosis (VTE), specifically the VEINES-QoL/Sym questionnaire and the PEmb-QoL questionnaire. The electronic adaption and cross-cultural translation processes followed the international guidelines recommended by ISPOR. The migration of the questionnaires from paper to electronic versions was conducted in the Research Electronic Data Capture (REDCap). Following approval of the electronically adapted and translated versions, a pretest of the questionnaires was performed by cognitive interviewing patients with VTE recruited from a hospital setting. Nine men and ten women between the age of 19 and 73 years participated in cognitive interviews. The questionnaires were successfully adapted from paper to electronic versions, and during the migration process only a few modifications to the content and format were made. Most comments were related to technicalities, e.g. touch functions and checkboxes. The cross-cultural translation of both questionnaires was satisfactory, as only minor rephrasing was required. The original and Danish version of VEINES-QoL/Sym and PEmb-QoL were successfully adapted into electronic versions and are ready to share for REDCap users. Furthermore, the Danish versions of the two questionnaires have shown satisfactory face validity.

Validation of the Polish version of the Self-Evaluation of Communication Experience after Laryngectomy (SECEL) questionnaire

&lt;b&gt;&lt;br&gt;Introduction:&lt;/b&gt; A total laryngectomy can impact multiple aspects of a patient’s life. Self-Evaluation of Communication Experience after Laryngectomy (SECEL) is a questionnaire adapted specifically for self-assessment of communication within laryngectomized patients.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Aim:&lt;/br&gt; The following study aims to evaluate the accuracy, reliability and validity of the Polish version of the questionnaire.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Material and methods:&lt;/b&gt; The sample population consisted of 33 patients using the tracheoesophageal voice. All patient fulfill following questionnaires: SECEL, VHI, EORTC QLQ-C&lt;sub&gt;30&lt;/sub&gt; and EORTC QLQ-H&amp;N&lt;sub&gt;35&lt;/sub&gt;. The objective tests included diadochokinesis (DDK) and maximum phonation time (MPT). The statistical analysis was performed with Wilcoxon’s signed-rank test, Spearman’s Rank Correlation Coefficient, Cronbach’s alpha coefficient, the standardized alpha coefficient, the U-MannWhitney test, and the Kruskal-Wallis test.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Results:&lt;/b&gt; The results proved very good internal coherence of the Polish version of SECEL questionnaire, with Cronbach’s alpha coefficient reaching the value of 0.92 and the standardized alpha coefficient being 0.93. The results demonstrated high reliability of the test’s reproducibility (Spearman coefficient 0,73). Statistical analysis indicated a high correlation between both SECEL and VHI, and SECEL and the subscale of Speech Problems of H&amp;N35 questionnaire. SECEL results were not correlated with MPT(a) and DDK. The results obtained are comparable to those provided in previous language- specific validations of the SECEL questionnaire.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Conclusion:&lt;/b&gt; The Polish version of the SECEL questionnaire has satisfactory internal coherence, reliability and reproducibility. Furthermore, the results of statistical analysis of the Polish-language version of SECEL remain consistent with those obtained by the authors of other validations. The aforementioned data is sufficient for the proposal to widespread the Polish translation of the SECEL questionnaire in clinical practice.&lt;/br&gt;

Validation of a German version of the Boredom Proneness Scale and the Multidimensional State Boredom Scale

The scientific interest in boredom is growing over the past decades. Boredom has not only been linked to symptoms of psychopathology, but also shows a remarkable effect on individual behavior under healthy conditions. Current characterizations of boredom in humans mostly rely on self-report assessments which proved to faithfully reflect boredom in a vast range of experimental environments. Two of the most commonly used and prominent self-report scales in order to assess boredom are the Multidimensional State Boredom Scale (MSBS) and the Boredom Proneness Scale (BPS). Here, we present the German translations of both questionnaires and their validation. We obtained and analyzed psychometric data from more than 800 healthy individuals. We find that the German MSBS and BPS show vast congruence with their originals in respect to item statistics, internal reliability and validity. In particular, we find remarkable associations of state boredom and trait boredom with indicators of mental burden. Testing the factor structure of both questionnaires, we find supporting evidence for a 5-factor model of the MSBS, whereas the BPS in line with its original shows an irregular, inconsistent factor structure. Thus, we validate the German versions of MSBS and BPS and set a starting point for further studies of boredom in German-speaking collectives.

Psychometric Properties of the Persian Translation of the 12-Item Utah Photophobia Symptom Impact Scale Questionnaire

ABSTRACT To translate the the Utah Photophobia Symptom Impact Scale-12 questionnaire into Persian and assess the psychometric aspects to check its validity and reliability based on the Rasch modelling method. Translation and cultural adjustment of the English language UPSIS-12 questionnaire to Persian was undertaken. A total of 61 patients with complaints of photophobia participated in evaluating validity and reliability aspects. All the participants were asked to complete the Persian translation of the UPSIS-12 questionnaire. Rasch analyses of the survey items were conducted using WINSTEPS. All items fit the Rasch model. Point-measure correlation values varied from 0.41 to 0.77, providing a preliminary indication of adequate construct validity. All factor loadings were found more than 0.4. All items obtained infit and outfit mean square (MnSq) values of < 2.0. All participants except 5 had normal outfit values. Patients’ abilities relative to the items’ difficulty were analysed. Item difficulty was estimated and item characteristic curves were included. Sufficient unidimensionality, hierarchical order, and equal interval scoring were obtained. In conclusion, the Persian UPSIS-10 questionnaire has excellent psychometric properties and it will be valuable in both clinical practice and research. It will help Persian practitioners to assess their patients’ photophobia.

Assessing suboptimal health status in the Saudi population: Translation and validation of the SHSQ-25 questionnaire.

Suboptimal Health Status (SHS) is realised as a vital feature for improving global health. However, the Arabian world does not have a validated instrument for screening SHS in their population. Therefore, the study aimed to evaluate the psychometric properties of Arabic-translated SHS (ASHSQ-25) in the Saudi Arabian population. We conducted a cross-sectional study among the conveniently sampled 1590 participants from the Saudi population (with a 97.4% response rate). The data was gathered through an online survey and then exported into SPSS and AMOS version 26.0 for analysis. Mann-Whitney and Kruskal-Wallis tests were used to identify the median difference between demographic groups. The one-tailed 90% upper limit of SHS scores was chosen as the cut-off criteria for SHS. Reliability and confirmatory analysis were performed for the psychometric evaluation of ASHSQ-25 in the Saudi Arabian context. This study demonstrates that the ASHSQ-25 has good internal consistency, interclass correlation coefficient (ICC) = 0.92; 95% confidence interval (CI) = 0.91-0.93) and reliability (Cronbach's α = 0.92). The confirmatory factor analysis (CFA) results indicated a good fit of the databased on the CMIN/degrees of freedom (df) = 4.461, comparative fit index (CFI) = 0.94, Tucker Lewis index (TLI) = 0.93, and Root Mean Square Error of Approximation (RMSEA) = 0.05. The result factor loadings for each item were high (≥ 0.55), except for one item from the immune system subscale. The SHS cut-off point for ASHSQ-25 was 33, leading to a 23.7% prevalence of SHS. This study reveals that ASHSQ-25 has appropriate internal consistency and structural validity to assess SHS in an Arabic-speaking population; therefore, it is recommended.

Translation of the nine item avoidant/restrictive food intake disorder screen (NIAS) questionnaire in French (NIAS-Fr).

The Nine Item Avoidant/Restrictive Food Intake Disorder (ARFID) Screen (NIAS) questionnaire is originally available in English. Given the significant overlap of ARFID-like symptoms in gastrointestinal (GI) diseases, ARFID screening becomes crucial in these patient populations. Consequently, the translation of the NIAS questionnaire into French is necessary for its utilization in French-speaking countries. Clinical experts in neuro-gastroenterology and dietetics from four medical centres in two French-speaking countries (France and Belgium) took part in a well-structured questionnaire translation procedure. This process involved six steps before final approval: translation from English to French, backward translation, comparison between the original and retranslated versions, testing the translated version on patients, making corrections based on patient feedback, and testing the corrected version on an additional sample of patients. The NIAS questionnaire in French (NIAS-Fr) was tested on 18 outpatients across the involved centres. For the majority of native French-speaking patients, the translated questionnaire was well understood and clear. After incorporating two relevant modifications suggested by the patients, the translated questionnaire was approved through testing on an additional sample of patients. The involvement of two French-speaking countries was crucial for the harmonization and cultural adaptation of the questionnaire. As a result, the NIAS-Fr is now available for use in 54 French-speaking countries, serving approximately 321 million French speakers across five continents for screening ARFID, for both clinical and research purposes.

Polish Translation and Linguistic Validation of the SCAR-Q.

Introduction Patient-reported outcome measurements (PROMs) are gaining considerable popularity as tools to assess the effectiveness of the treatment in plastic surgery, being a complement to surgical outcomes. The SCAR-Q questionnaire has been recently developed for patients with surgical, traumatic, and burn scars. Aim The study aims to describe the process of translation and linguistic validation of the scar questionnaire (SCAR-Q) for use in Polish patients undergoing scar treatment. Material and methods An official Polish translation and language validation of the SCAR-Q were done in adherence to International Society for Pharmacoeconomics and Outcomes Research (ISPOR) guidelines. The process consisted of four steps: two independent forward translations, a back translation, a review of the back translation, and cognitive participant interviews. Results The field-tested version of the SCAR-Q consisted of 29 items across three scales measuring appearance concerns, symptoms, and the psychosocial impact of the scar. The forward translation was done by two independent translators and revealed specific difficulties in translation to the Polish language (4/29 items). The back translation showed no significant differences compared to the original English version. Cognitive debriefing interviews involved nine Polish patients with postraumatic scars, burn scars, and scars after skin tumor resection. Participants have not reported any major difficulties in understanding the content of the questionnaire. Conclusions The ISPOR provides a straightforward and thorough guideline for the PROMs translation process. The new SCAR-Q is an accessible and efficient PROM that can be implemented in Polish patients to assess the effectiveness of scar treatment.

Validity and Reliability Test of the Medication Adherence Report Scale (MARS) Questionnaire for Tuberculosis (TB) Patients

In terms of tuberculosis cases, Indonesia is second only to India. Successful outcomes in the treatment of tuberculosis depend on patient compliance with their prescribed medication. The MARS (Medication Adherence Report Scale) questionnaire can be used to assess medication adherence in tuberculosis patients. The researchers in this study set out to see if the MARS questionnaire was sufficiently valid and reliable to be used with tuberculosis (TB) patients in Indonesia. Descriptive quantitative analysis using a cross-sectional design was employed for this study. The MARS survey was the instrument used for this study. Sixty tuberculosis patients from the Lamongan District Health Center met the inclusion criteria and made up the sample size of 70. Sampling with the help of a planned strategy. Apply the Pearson Product Moment correlation test to the questionnaire to see if it is reliable. The Cronbach alpha coefficient was used to determine the questionnaire's reliability in this study. According to the data, the r count correlation value was higher than the r table value of 0.2542. The Cronbach Alpha Coefficient obtained from the reliability analysis was 0.486. The results of the validity and reliability tests indicated that the Indonesian translation of the MARS questionnaire was a valid and reliable tool for gauging the degree to which TB patients took their prescribed medications as directed. Adherence should be measured with a reliable questionnaire or instrument to ensure accurate results.

Forward and Back is Not Enough: Applying Best Practices for Translation of Pediatric Sleep Questionnaires.

Cultural differences in the experience of sleep warrant consideration in the measurement of sleep across populations. This requires careful attention to both language and culture when translating survey measures. While forward and back translation is the most commonly used approach, it has numerous limitations if used as an isolated method. Best practice guidelines recommend a multi-step team-based approach for translating questionnaires. We present our recent experience applying best practices in a study with both Spanish and English-speaking Mexican American mothers of toddlers. This work is part of a larger project that will measure parental sleep-related beliefs and parenting practices in Mexican American parents of toddlers. We utilized a team-based approach to translation and cultural adaptation, assembling a diverse, bilingual, and bicultural team. The translation process started with items and measures that we had selected, revised as needed, or created. New items were based on constructs identified in semi-structured interviews and focus groups used to explore parental sleep-related beliefs and parenting practices in the target population. Following this, our translation process included forward and back translation, harmonization and decentering, cognitive interviewing, debriefing, adjudication, and proofreading. We outline details of our process and the rationale for each step. We also highlight how each step contributes to ensuring culturally appropriate items with conceptual equivalence across languages. To ensure inclusivity and scientific rigor within the field of sleep research, investigators must utilize best practices for translations and cultural adaptations, building on the foundation of cultural constructs often identified in qualitative work.

Translation, cross-cultural adaptation and validation of the Arabic multimorbidity treatment burden questionnaire (MTBQ-A): A study of adults with multimorbidity

BackgroundStudies internationally have found that a high treatment burden is associated with several long-term conditions and poor quality of life. ObjectivesTo translate, culturally adapt, and provide evidence of reliability, validity, and factor structure of the Multimorbidity Treatment Burden Questionnaire for use among Arabic-speaking adults with multimorbidity. MethodsStandard guidelines for the cross-cultural adaptation of self-report measures were followed. The original 10-item MTBQ was translated into Arabic by professional translators using forward-backward translation. An expert group, including the creator of the MTBQ, participated in the cultural adaptation and content validity, followed by cognitive interviewing and pilot testing. The questionnaire was then tested on 177 Arabic-speaking patients with multimorbidity recruited from community pharmacies in the United Arab Emirates. The distribution of responses, dimensionality, internal consistency reliability, and construct validity were examined. ResultsThe content validity of the MTBQ-A was good (Content Validity Index = 0.94), and cognitive interviews found that the items were well understood. The scale showed positive skewness and high floor effects. Factor analysis supported a two-dimensional structure (factor loadings >0.4): factor one was named “Self-management and social support,” and factor two was named “Burden of visiting health care services and health care professionals”. The questionnaire had good internal consistency (α = 0.83). As predicted, a higher MTBQ score in both factors was associated with poor health-related quality of life in all dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression (p values < 0.05); and negatively correlated with self-efficacy in taking medication (p < 0.01) and in learning about medication (p < 0.01). ConclusionsThe Arabic MTBQ is a valid and reliable measure of treatment burden with good construct validity and internal consistency. This easy-to-understand questionnaire can be used to assess the perceived treatment burden among Arabic-speaking patients with multimorbidity.

Translation and cross cultural adaptation of the questionnaire "Quality of Alimentation" for brazilian portuguese.

We aimed to provide translation and cultural adaptation of the questionnaire "Quality of Alimentation" from English to Brazilian Portuguese. The transcultural translation process consisted of the following steps: translation of the original English version to Portuguese by two bilingual translators native in the targeted language; Reverse translation by two translators native in the original language; Review of reverse translation; Review of the Portuguese version from the questionnaire by a local committee of experts in bariatric surgery; Pre-trial to evaluate of clarity, comprehension, and overall acceptability by the target population. In its final Portuguese version, the questionnaire "Quality of alimentation" was found to be of clear comprehension and easy applicability. The questionnaire's translation and cultural adaptation for Brazilian Portuguese represents an important step towards improving food tolerance evaluation following bariatric surgery. Further studies are however necessary for validation of its psychometric properties in Brazil.

Validation of Polish version of Gastrointestinal Dysfunction Scale for Parkinson's Disease.

The Gastrointestinal Dysfunction Scale for Parkinson's Disease (GIDS-PD) is a novel, disease-specific self-report questionnaire used to quantitatively assess features of gastrointestinal dysfunction symptoms in patients with Parkinson's Disease. The aim of this paper was to validate the Polish translation of the scale, to summarise its consistency with the English language version, and to assess its clinimetric properties. Gastrointestinal dysfunction is a common and often debilitating manifestation of Parkinson's Disease (PD). Gastrointestinal symptoms are also considered to be prodromal features of this disease. To date, there has been no scale in Polish that has precisely assessed gastrointestinal symptoms in patients with PD. The GIDS-PD was translated into Polish by two investigators (M.K. and J.N.). A back-translation was completed by two separate investigators (M.F. and A.A.) who were not involved in the original translation. Afterwards, 10 Polish PD patients underwent cognitive pre-testing. After the final translation was officially approved by the Movement Disorder Society, it was tested on 64 individuals with PD during field testing. For the purpose of testing scale reliability, 20 of the patients recruited for field testing underwent the GIDS-PD for a second time after 8-12 weeks. The GIDS-PD demonstrated overall good consistency (Cronbach's alpha of 0.74, ICC of 0.74). Regarding the individual domains, the constipation subscore demonstrated good reliability, the bowel irritability subscore demonstrated moderate reliability, and the upper GI subscore demonstrated poor reliability. Upper GI symptoms seem to be less pronounced, and also more varied, in the Polish PD population than in its English language counterpart. This paper provides a validated Polish translation of the GIDS-PD questionnaire. We highly recommend using the GIDS-PD for research purposes, as well as everyday clinical practice in the Polish PD population.

Psychometric analysis and validation of the Persian translation of the systemic sclerosis questionnaire (SySQ).

Scleroderma is a complex multisystem disorder that could have effects on the quality of patients' lives. This study was conducted by determining the psychometric properties of the Persian version of the systemic sclerosis questionnaire (SySQ) that specifically assesses indications and functional limitations of scleroderma patients. In the present cross-sectional study, the method included: translation and back translation. Psychometric properties of the questionnaire including its content and face validity were assessed. Internal consistency with the SySQ (Cronbach's alpha) and reproducibility was by test-retest method. The factor structure of the questionnaire was evaluated using exploratory factor analysis. The convergent validity of the SySQ was assessed using the General Health Assessment Scale (HAQ). Altogether 32 SySQ items, the internal consistency coefficient (Cronbach's alpha) of the whole tool was 0.906. The content validity index was 0.98 and the content validity ratio was 0.796, there was a significant relationship between the questions and the relevant factors in the factor analysis. The correlation coefficient = 0.953 for the instrument. The correlation of SySQ dimensions with HAQ questionnaire dimensions in convergent validity showed that musculoskeletal dimensions, general condition, and cardiorespiratory of the questionnaire are correlated with all dimensions of the HAQ questionnaire. The Persian version of the questionnaire SySQ with competency is valid and reliable and is suitable for measuring specific changes in Persian systemic sclerosis patients.

Amending the Polish Adaptation of the Moral Foundations Questionnaire (MFQ-PL)

The current article aims at correcting some linguistic inconsistencies between the Polish and English versions of the 30-item Moral Foundations Questionnaire, and to develop a revised Polish translation more appropriate for cross-cultural comparison. Researchers who are not familiar with the Polish language and the English version of the Moral Foundations Questionnaire are likely to miss these inconsistencies between the English and Polish versions. These translation issues are of significant interest as the Moral Foundations Questionnaire has been utilized to compare human values across a wide range of cultures. In cross-cultural research, translational precision is important, as differences of meaning can lead researchers to draw illusory conclusions about differences between cultures. We offer a revised Polish translation of the 30-item Moral Foundations Questionnaire, which we believe more accurately represents the meaning and form of the English items. This new translation should facilitate more consistent comparisons of moral foundations between Polish and Non-Polish populations.
