Extracurricular internships and university students’ evaluation of higher learning: a cross-cultural adaptation perspective

PurposeAs competition in the graduate labor market intensifies, extracurricular internships have become increasingly popular among university students. This paper explores whether and how students’ evaluation of the higher learning that they have received changes during extracurricular internships.Design/methodology/approachWe interviewed 47 undergraduate students who had extracurricular internships across five Chinese universities. Data were analyzed innovatively through the lens of cross-cultural adaptation theory, which guides us to view internships as a transition from university culture to workplace culture through the stress-adaptation-growth dynamic.FindingsThe findings reveal that participants faced stress from multiple sources at the beginning of their internships, which collectively prompted them to adapt proactively to the workplace culture. While acquiring new habits and trying to acculturate into the surrounding work milieu, many participants deculturated from their old habits and student identity, putting aside higher learning. As the adaptation progressed, over half of the participants even began to critique university curricula and depreciate the value of higher learning.Originality/valueThe study offers theoretical insights into internships and the broader university-to-work transition as well as practical implications for universities in balancing learning and employability goals from a novel cross-cultural adaptation perspective.

Cultural Spanish adaptation, factor structure, and reliability of implementation science instruments for suicide prevention.

Research on the implementation of community gatekeeper training interventions for suicide prevention in Spanish-speaking countries is limited. Gatekeepers identify warning signs of suicidal behavior in at-risk population and refer them to specialized mental health care. To identify factors that influence the implementation of evidence-based practices, standardized measures are needed in Spanish. We culturally adapted and evaluated the factor structure and reliability of two measures for use in the Mexican population: the final version of Acceptability, Appropriateness, and Feasibility of the Intervention (Weiner et al., 2017), and the Organizational Readiness for Implementing Change (ORIC; Shea et al., 2014). Our study consisted of two consecutive phases. The first addressed the cross-cultural adaptation. In the second phase, we administered an online survey to a nonrandom sample of 453 middle school personnel and performed a confirmatory factor analysis (CFA). Participants were 73.95% female, 25.17% male, and 0.88% nonbinary/other and came from the 32 Mexican states. CFA indices for the Mexican Spanish version of the acceptability, appropriateness, and feasibility measure yielded values of comparative fit index (CFI) = 0.96, Tucker-Lewis fit index (TLI) = 0.94, root-mean-square error of approximation (RMSEA) = 0.05, and standardized root-mean-square residual (SRMR) = 0.03. Internal consistency was Ω = 0.95. CFA indices of the Mexican Spanish version of the ORIC were CFI = 0.95, TLI = 0.93, RMSEA = 0.08, and SRMR = 0.03, and internal consistency was Ω = 0.94. We conclude that both instruments show preliminary psychometric properties that support their validity and reliability in the Mexican Spanish-speaking context. These findings promise to drive research on the implementation of gatekeeper interventions and other evidence-based practices in Spanish-speaking school settings.

Validity and Reliability Study of the Turkish Form of the Family Support Scale for the Older People.

The Family Support Scale is a used scale to assess family support in older people. The purpose of this study was to test the Family Support Scale for older people in Turkish and to examine its validity and reliability. This was a methodological study. This study sample enrolled 250 older individuals. The study was conducted between July-December 2022. In data collection, sociodemographic information form and The Family Support scale were used. The inclusion criteria for this study selected participants who were 65 years or older, literate, open to communication, living with at least one family member, and who volunteered to participate in the research. In the study, who developed the original scale, was contacted via e-mail and the necessary permission was obtained for the Turkish validity and reliability of the scale. Language equivalence, content validity, exploratory factor analysis, and confirmatory factor analysis of the scale were performed. Internal consistency and total item score correlation were calculated to ensure validity and reliability. The scale is compatible in terms of language and content suitability, CVI (Language)= 0.87; CVI (Content)=0.099. In the validity analyzes of the scale; the factor loadings values of the scale were found to be between 0.36 and 0.83, and the explained variance (54.78%) was at a sufficient level according to the EFA results. It was determined that factor loading values for all items were varied between 0.58 and 0.97 and factor load values were statistically significant in CFA (p<.05). It was determined that the fit indices were RMSEA=0.064, GFI=0.99, CFI=0.99, NFI=0.99, x2/df=2.03 at the desired level. In the reliability analysis, it was found that the internal consistency coefficient (α: 0.94) was quite reliable, and the total correlation values of the scale ranged between 0.48 and 0.83. The cross-cultural adaptation of this scale has been realized successfully in Turkish. Health care providers may utilize this tool to evaluate family support for older people.

The Italian version of the Majeed pelvic score: translation, cross-cultural adaptation and validation.

The assessment of functional outcomes after pelvic ring fracture remains a controversial topic. The Majeed pelvic score (MPS) is the most commonly used pelvic-specific questionnaire in the literature. The aim of this study is translation, cross-cultural adaptation and validation of the Italian version of MPS. The study was articulated in two phases. Phase 1 consisted in translation and cross-cultural adaptation of MPS, from English into Italian. The psychometric properties were tested on 52 Italian patients (Phase 2). Construct validity was assessed by correlation with Short-Form 12 (SF-12). 33 patients repeated the questionnaire after 14days to assess its reproducibility. All data were subsequently analyzed (descriptive statistics, multitrait analysis, reliability and construct validity assessment). The questionnaire was clear and easily understood (no missing data). A ceiling effect was detected for all items of the scale. Multitrait analysis showed good results for each outcome measure, except for the item "walking distance" that showed poor item discriminant validity. A significant correlation between the MPS and the physical component summary (PCS) of the SF-12 was found, while there was a weak correlation with the mental component summary (MCS). The questionnaire showed high internal consistency (Cronbach's alpha: 0.91-0.99) and very good test-retest reliability (intraclass correlation coefficients: 0.92-0.96). The Italian version of the MPS has demonstrated to be reliable and valid in the evaluation of patients with pelvic ring fractures. There is still however a need for an instrument capable of evaluating the mental component in these types of injuries.

Enhancing reflective practices in higher education with AI-supported anthropomorphic coaches

This paper reports on a pilot study exploring the use of generative AI and anthropomorphic coaches to enhance students’ reflective practices. Reflective practice is crucial for critical thinking and self-awareness. AI-driven feedback systems and lifelike avatars may create interactive, engaging environments for deeper student reflection. Drawing on observations from an ongoing project using Soul Machines Studio at the University of Auckland Business School, this inquiry considers anthropomorphic AI coaches’ ability to provide timely feedback and support reflective work in postgraduate courses. As a work-in-progress, we describe two use cases: (a) Refining team collaboration through AI-guided reflection and (b) providing feedback on reflective journal writing. We also outline future work on scalability, longitudinal studies, learning management system integration, cross-cultural adaptation, and ethical frameworks. We highlight AI's potential to develop students’ reflective practices and contribute to integrating advanced technologies in education.

Translation and cross-cultural adaptation of the self evaluation of breathing questionnaire (SEBQ) into Danish

ABSTRACT Background and Purpose Dysfunctional breathing (DB) with or without an underlying medical condition is associated with impaired quality of life. DB-related symptoms can be measured with the 25-item Self Evaluation of Breathing Questionnaire (SEBQ). However, the SEBQ is not available in Danish.The aim of the present study was to translate and cross-culturally adapt the SEBQ into Danish and to assess the face validity of the Danish version of the questionnaire in individuals with DB-related symptoms. Materials and Methods The SEBQ was translated and cross-culturally adapted into Danish using an internationally acknowledged six-step forward-backward translation guideline in an interactive process with an expert committee of clinicians, translators, methodologists and the SEBQ developer. Face validity was explored through semi-structured interviews with 24 adult individuals with DB-related symptoms (age 20–70 years, female n = 14). Results The SEBQ was successfully translated and cross-culturally adapted into Danish. Three major modifications were made following the translation process and participant interviews. First, an introductory paragraph, including a recall period of the previous seven days, was added. Second, the administration of the questionnaire was changed from a paper to an electronic version. Finally, adaptations regarding semantic equivalence, especially concerning being ‘breathless’ and ‘short of breath’, were performed. The participants expressed that the final version of the SEBQ embraced their DB-related symptoms, was understandable, and easy to complete. Conclusion The SEBQ is the first available Danish questionnaire to measure DB-related symptoms, following an internationally acknowledged cross-cultural adaptation and face validity evaluation approach. This promising validation should be followed by an assessment of measurement properties in individuals with DB-related symptoms to investigate the adequacy of the SEBQ in a Danish context.

The Spanish Adaptation of the Quality in Psychiatric Care—Forensic Inpatient (QPC-FIP) Instrument: Psychometric Properties

Background/Objectives: The quality of care in forensic mental health services is a factor that significantly impacts recovery and constitutes a right of the individuals receiving treatment. However, there is a lack of instruments to assess the perceived quality of care among individuals in this setting. Quality in Psychiatric Care—Forensic Inpatient (QPC-FIP) is a Swedish instrument that measures the perception of quality care from the perspectives of patients in the forensic setting. The aim of this study was to perform a cross-cultural adaptation of the QPC-FIP instrument into Spanish and to assess its reliability and validity. Methods: For the adaptation process, a translation–backtranslation of the instrument was performed. Regarding psychometric properties, the sample consisted of 120 inpatients in the forensic setting to whom the instrument was applied. To assess temporal stability, the instrument was readministered after 10 days (n = 98). Results: The confirmatory factor analysis showed an equivalent seven-factor structure with the original version, presenting a satisfactory model fit. Regarding reliability, the Cronbach’s alpha value was 0.933, and the intraclass correlation coefficient was 0.836 (95% IC: 0.742–0.896), revealing results higher than 0.70 in six of the seven factors. Conclusions: The Spanish version of the QPC-FIP instrument showed adequate validity and reliability values, indicating that is a useful tool for measuring quality in psychiatric care in the forensic context.

STRATEGIES FOR PRAGMATIC IMPROVEMENT IN THE TRANSLATION OF PUBLIC SIGNS AT ZHAOQING XINGHU NATIONAL PARK FROM THE PERSPECTIVE OF HIGH-QUALITY DEVELOPMENT

As the only national 5A-level tourist attraction in Zhaoqing, the Xinghu National Park serves as a crucial window for cultural dissemination and city branding. This paper systematically analyzes the current state of Chinese-English translations of public signs at this scenic area, identifying issues such as spelling and grammar mistakes, and overly literal translations. These errors reduce the effectiveness of information transmission and weaken cross-cultural communication. To address this, based on the concept of high-quality development, this paper proposes a multi-layered strategy involving translation standardization, cross-cultural adaptation review, and professional training, aiming to enhance the international image and cultural outreach of the Xinghu National Park, and to serve as a reference for other tourist sites. KEYWORDS: Zhaoqing Xinghu National Park, Chinese-English translation, pragmatic failure, cross-cultural communication, translation norms

Hindi version of the lower extremity functional scale: a study of translation, validation and cross-cultural adaptation

BACKGROUND: Lower Extremity Function Scale (LEFS) serves as a patient-reported outcome measure, used to evaluate the functional status of lower extremity in different musculoskeletal conditions. It was originally developed in English language (E-LEFS) and numerous translations in different languages are available to measure its usability among different cultures. OBJECTIVES: To translate the English version of the Lower Extremity Function Scale (E-LEFS) into Hindi language and to evaluate its content validity, cross-cultural adaptation along with the concurrent validity and reliability. METHOD: Process of forward and backward translation was carried out by two bilingual translators and a physiotherapist after obtaining developer’s approval, for which the Beaton guidelines were used. For the content validation, Delphi method of was employed in which 12 field experts of more than 5 years of experience participated. Cultural adaptation procedures were then carried out with 12 patients, who reported in out-patient department of the hospital through convenience sampling who were asked about whether the H-LEFS was well understood by the patients. Their responses were recorded as positive and negative responses. This process was followed by concurrent validation which was conducted by comparing the scores with the SF-36 scale, involving 30 patients with activity limitation in their daily life. Lastly, 50 patients were recruited for intra-rater reliability testing. RESULT: The scale was successfully translated and verified by the bi-lingual language experts. Content validity came out to be significant with each item scoring more than 0.92. Nearly all items, excluding item no. 8, 16, 17, 18, and 19 received universal agreement with a content validity ratio of 1. The average scale-level validity stood at 0.98, indicating excellent level of validity and the scale was found to be well adapted by the native people as out of 12 patients, 10 patients provided 100% positive response. Concurrent validation using Pearson’s correlation coefficient came out excellent with the values of 0.993 for E-LEFS and 0.890 for SF-36. Cronbach's alpha and ICC values were calculated as 1.00 for Intra-rater reliability. CONCLUSION: LEFS was well translated into Hindi language with an excellent content and concurrent validity and is found to be highly reliable. Hence, it is recommended for the usage of native Hindi speaking population.

Translate and cross-culturally adapt the original English version of the lower extremity functional scale into the Sinhalese version

Objectives: Functional ability is critical for quality of life (QOF), and its evaluation is vital in a clinical context. However, there is a deficiency of a universally recognized grading scale in Sinhala for assessing functional capacity in athletes with lower extremity musculoskeletal conditions. This research aimed to validate the linguistic and cross-cultural adaptation of a translated Sinhala version of the lower extremity functional scale (S-LEFS). Materials and Methods: A two-stage observational study was conducted. The lower extremity functional scale was cross-culturally adapted to Sinhala through independent, double forward, and backward translation. An experienced clinical researcher tested the translated version to establish the linguistic validation of S-LEFS. The finalized version was validated for construct, convergent, and criterion validity. A total of 112 participants, comprising 57 healthy (50.89%) and 55 unhealthy (49.11%) lower limb athletes, completed S-LEFS. Results: S-LEFS demonstrated excellent reliability with a Cronbach’s alpha of 0.952. Exploratory factor analysis revealed good factor loadings (&gt;0.48) for all 20 items, with three components accounting for 70.63% of cumulative variance. Scale got a sensitivity of 87.5% and specificity of 81% at a cutoff point of 67.5. Kaiser-Meyer-Olkin (KMO) value was 0.918 (P &lt; 0.0001), and Bartlett’s Test of Sphericity was significant (P &lt; 0.01). No correlation was detected between S-LEFS and World Health Organization QOF-Bref (r = 0.281). Conclusion: S-LEFS is a reliable and valid tool for evaluating lower limb function in athletes.

Chinese translation and validation of the Personalized Psychological Flexibility Index (PPFI) for medical college students

BackgroundPsychological flexibility (PF) is defined as the ability to pursue valuable life goals despite the existence of distress. The Personalized Psychological Flexibility Index (PPFI) is a new measure of psychological flexibility that can address existing deficiencies. This study aimed to translate and validate the psychometric characteristics of the Chinese version of the PPFI among medical college students.MethodsThe study was conducted in two phases. Phase 1 involved the translation and cross-cultural adaptation of the PPFI according to guidelines recommended by the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Phase 2 was a cross-sectional survey conducted on 945 medical college students in China. The psychometric performances of the scale were assessed using construct validity, divergent validity, criterion validity, incremental validity, internal consistency, and test-rest reliability.ResultsThe exploratory factor analysis (EFA, n1 = 440) showed that the Chinese version of the PPFI consisted of 3 factors, with a total of 15 items. The confirmatory factor analysis (CFA, n2 = 440) showed that the three-factor structure fit well (χ2/df\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$$df$$\\end{document}=2.469, SRMR = 0.051, RMSEA = 0.058, GFI = 0.94, CFI = 0.985). The total Chinese PPFI score had a moderate positive association with the Comprehensive Assessment of Acceptance and Commitment Therapy (CompACT, r = 0.344) and a negative association with the Acceptance and Action Questionnaire-II (AAQ-II, r = -0.334). Furthermore, the Chinese PPFI demonstrated good internal consistency (Cronbach's α = 0.826) and test–retest reliability (ICC = 0.817, p < 0.001).ConclusionThe 15-item Chinese version of the PPFI is a reliable and valid tool for measuring PF in Chinese medical students. However, additional studies are needed to validate its psychometric properties in more generalizable samples and other contexts.

Evaluation of the Arabic version of the Asthma Trigger Inventory among asthmatic pediatric patients in Saudi Arabia

Background Asthma Trigger Inventory (ATI) is available in English, German, and Spanish languages, however, a version in Arabic language specifically tailored for identifying asthma triggers within Saudi Arabia has been missing. Objectives To assess the reliability and validity of the adapted Arabic ATI among parents of asthmatic children in Saudi Arabia. Methods A cross-cultural adaptation of the ATI was conducted, adding seven region-specific triggers to reflect cultural and environmental factors. The Pediatric Asthma Quality of Life Questionnaire (PACQLQ) was used to assess quality of life. Construct validity of the Arabic ATI was evaluated via exploratory factor analysis (EFA), and reliability was measured with Cronbach’s alpha. Results EFA yielded a KMO of 0.634 and a significant Bartlett’s Test (χ2 = 10,005.076, p < 0.001). Six trigger subscales showed high reliability (α > 0.90), though Middle Eastern triggers had lower internal consistency (α = -0.11). Physical and psychological triggers correlated significantly with poorer quality of life (exercise: r = -0.662, p < 0.001; psychological: r = -0.307, p < 0.001). Air pollution and Middle Eastern triggers correlated positively with quality of life (r = 0.222, p < 0.001 and r = 0.245, p < 0.001). Conclusion The Arabic version of the ATI exhibited robust reliability and validity when administered to parents of asthmatic children in Saudi Arabia. Additional research is warranted to further validate its applicability across various Arabic-speaking populations.

Transcultural adaptation and validation of the Eating Self-Efficacy Brief Scale (ESEBS): the Brazilian version

PurposeThis study aimed to develop and validate the Brief Eating Self-Efficacy Scale (ESEBS-BR) in Brazilian Portuguese, addressing the lack of tools to assess eating self-efficacy beliefs in Portuguese-speaking populations.MethodThe study sought to cross-culturally adapt the scale, evaluate its internal structure, validate its reliability and validity, and explore potential associations between eating self-efficacy and eating behaviors. The cross-cultural adaptation process involved translation and back-translation, expert committees, and pre-testing. Scale validation was conducted with 228 participants, including reliability analyses, confirmatory factor analysis, and correlations with established measures of eating behavior.ResultsThe ESEBS-BR, maintaining all 8 original items, demonstrated high reliability, with a two-factor structure model confirmed by confirmatory factor analysis. Significant correlations were found between ESEBS-BR scores and measures of binge eating and eating behaviors, validating its criterion validity.ConclusionsThe development and validation of the ESEBS-BR represent a significant contribution to the assessment of eating self-efficacy in the Brazilian population. The scale proved to be sensitive, reliable, and valid, offering an important tool for research and clinical interventions related to eating behavior.Level of evidence: V, descriptive cross-sectional study.

Cross-cultural Adaptation of the Iranian Version of the Voice Symptom Scale

Background and Objectives: This research aims to evaluate the validity and reliability of the Persian version of the voice symptom scale (VoiSS) questionnaire. We also sought to determine the best cut-off point to classify high-risk populations into controls (participants) and dysphonic patients. Methods: The study was conducted in 3 main steps. The translation process was carried out by a pair of Iranian bilingual speech-language pathologists along with an expert panel. For the validity study, the questionnaire was administered to 268 cases that were suspected of dysphonia. Finally, to assess the reliability, the questionnaire was completed twice in 2 weeks by 40 dysphonia patients. To normalize data generation 107 individuals without dysphonia completed the P-VoiSS, after that the cutoff value of the P-VoiSS was calculated. Results: Cronbach’s α was estimated at 0.914, and for impairment, emotional, and physical domains, it was 0.877, 0.926, and 0.725, respectively. We also estimated intra-cluster correlation (ICC) of 0.984 indicating high reproducibility of the Persian VoiSS questionnaire. The estimated intra-cluster correlation (ICC) for subscale was 0.962 for impairment, 0.989 for emotional, and 0.952 for physical domains. The Mean±SD score of the questionnaire for the healthy group was 10.1±5.9, while it was statistically higher in dysphonia patients (44.1±20.6). The statistical difference was observed in the subscales of the questionnaire between healthy and dysphonia groups (P&lt;0.05). The exploratory factor analysis determined that the Persian VoiSS has three subtest/latent factors like the original form. We also estimate the best cut-point at 20.5. Conclusion: The Persian adaptation of VoiSS is a dependable and effective tool that can be utilized for screening high-risk populations.

Slovenian Translation, Cross-Cultural Adaptation, and Content Validation of the Updated Oslo Sports Trauma Research Center Questionnaire on Health Problems (OSTRC-H2).

The updated Oslo Sports Trauma Research Questionnaire on Health Problems (OSTRC-H2) has been translated into a limited set of languages and lacks full validation of its new measures. To (1) translate, cross-culturally adapt, and evaluate the measurement properties of the OSTRC-H2 for the Slovenian population and (2) investigate the construct validity for the severity score and time lost due to a health problem. Cohort study (diagnosis); Level of evidence, 3. The OSTRC-H2 was translated from English to Slovenian (OSTRC-H2-SLO) according to international guidelines. A 15-week study was conducted among 188 elite athletes, with a test-retest performed in the 10th week. Internal consistency, reliability, content validity, feasibility, and potential ceiling effects were investigated. Internal consistency was measured using the Cronbach alpha coefficient, while reliability was measured with the intraclass correlation coefficient (ICC). Construct validity was measured with the Spearman rank correlation coefficient (r S). There was a 95% response rate and an 18% mean weekly prevalence of health problems. The OSTRC-H2-SLO showed excellent test-retest reliability (ICC, 0.94 [95% CI, 0.67-0.99]), with a Cronbach α of .93. A strong positive correlation was found between the OSTRC-H2-SLO severity score and days lost due to an acute injury (r S = 0.754), overuse injury (r S = 0.785), and illness (r S = 0.894) (P < .001 for all). Moderate to strong negative correlations were observed between severity score and total load (training and competition load in hours) as well as between days lost and total load (P < .001 for all). The OSTRC-H2-SLO was found to be valid, reliable, and well accepted among Slovenian athletes. The authors confirmed the questionnaire's construct validity and identified total load as an indicator of an increase in the severity score. NCT05471297 (ClinicalTrials.gov identifier).

Cross-cultural adaptation and validation of a revised Italian Anterior Knee Pain Scale version.

The study aimed to validate a revised Italian version of the Anterior Knee Pain Scale (AKPS) by addressing shortcomings in previous adaptations and following the COSMIN guidelines to ensure robust psychometric evaluation. One hundred thirty patients with anterior knee pain symptoms were recruited, with 65 undergoing a retest after 7 days to assess the scale's reliability. Structural validity was assessed through confirmatory factor analysis (CFA) to evaluate the scale's dimensionality. Internal consistency was measured using Cronbach's alpha, while test-retest reliability was assessed using the intraclass correlation coefficient (ICC). Measurement error was evaluated using the standard error of measurement (SEM) and the smallest detectable change (SDC). Construct validity was examined by correlating the AKPS with other established scales, including the Knee Injury and Osteoarthritis Outcome Score, Internal Knee Documentation Committee, Victorian Institute of Sport Assessment - Patella, Short-Form 36 Health Survey, and the Visual Analogue Scale. The CFA supported a three-factor model encompassing pain intensity and interference, functional limitations in daily activities, and knee structural and functional issues. The scale demonstrated good internal consistency (Cronbach's α=0.79) and excellent test-retest reliability (ICC=0.91), with low measurement error (SEM<5%). Construct validity was confirmed through moderate-to-strong correlations with related scales, particularly in domains related to pain intensity, symptoms, and daily functioning. The newly validated scale, demonstrating strong psychometric properties, meets international standards for clinical assessment tools, making it a reliable and effective instrument for assessing anterior knee pain in the Italian context.

Cross-cultural adaptation and measurement properties of the Brazilian Portuguese Version of the Parkinson’s Disease Sleep Scale (PDSS-2)

ObjectivesThe Parkinson’s Disease Sleep Scale-2 (PDSS-2) is an updated tool designed to identify specific sleep disturbances in individuals with Parkinson’s disease (PD). However, for its application in Brazil, a process of cross-cultural adaptation and validation of measurement properties was required. MethodsThis methodological study adapted the PDSS-2 to Brazilian Portuguese (PDSS-2-Br) and assessed its measurement properties (Internal consistency, test-retest reliability, measurement error, construct validity, and interpretability). The adapted scale was then tested on 2 occasions within an interval of 7 days, to 50 individuals with PD. Test–retest reliability was evaluated using kappa statistics (k) for the individual items, intraclass correlation coefficient (ICC) for the total scores, standard error of measurement (SEM), minimal detectable change (MDC) and Bland-Altman plot. Construct validity was assessed through Spearman correlation coefficients between the PDSS-2-Br and independent variables, while interpretability was evaluated by examining ceiling and floor effects. ResultsPDSS-2-Br showed satisfactory semantic, idiomatic, cultural, and conceptual equivalence. It also demonstrated good internal consistency (α=0.64), adequate test-retest reliability between items (κw 0.42-0.94, 95% CI=0.30-0.95) and total score (ICC=0.94; 95% CI=0.89-0.96), acceptable measurement error (SEM, 2.07 points; MDC, 5.74 points), absence of ceiling and floor effects, and 87,5% of pre-defined hypotheses were confirmed, indicating adequate construct validity (Spearman correlations coefficients for the rs=0.50, p<0.001) of the PDSS-2-Br. ConclusionThe measurement properties of the PDSS-2-Br are equivalent to those of the original version, and the scale has been validated and confirmed as reliable to measure sleep disorders among the Brazilian population with PD.

Brazilian Portuguese version of questionnaires assessing evidence-based practice competencies in healthcare students: Translation, cross-cultural adaptation, and measurement properties

BackgroundWhile several instruments assess evidence-based practice (EBP) competencies, few are available for the Brazilian population, particularly healthcare students. ObjectiveTo perform a cross-cultural translation of the Student Evidence-Based Practice Questionnaire (S-EBPQ) and Evidence-Based Practice Evaluation Competence Questionnaire (EBP-COQ) into Brazilian Portuguese; to adapt and validate the Brazilian Portuguese versions for use with healthcare students from diverse courses; and to assess the measurement properties of the translated and adapted versions. MethodsFour hundred forty-two healthcare students were included, and three versions were tested: S-EBPQ-BR, EBP-COQ-BR for nursing students, and EBP-COQ-BR for healthcare students. We assessed internal consistency, reliability, construct validity, responsiveness, and ceiling/floor effects. For reliability, participants completed the questionnaires twice, one week apart. For responsiveness, they completed them after participating in an educational program. ResultsNo issues were identified with understanding or applicability. For overall scores, the translated questionnaires demonstrated strong internal consistency (Cronbach's alpha=0.87-0.92), good to moderate reliability (ICC3,1=0.63-0.88), construct validity with moderate to very strong correlations to the Evidence-Based Practice Questionnaire (r=0.43-0.89), no ceiling or floor effects, and adequate responsiveness with significant pre- and post-educational program score differences. For subscales, the majority of them demonstrated satisfactory measurement properties, except for S-EBPQ-BR attitude (low internal consistency, poor reliability, and ceiling effect), EBP-COQ attitude (inadequate construct validity), and EBP-COQ skills (inadequate construct validity). ConclusionThe Brazilian Portuguese versions of S-EBPQ and EBP-COQ exhibit strong measurement properties, including high internal consistency, adequate reliability, valid construct validity, and responsiveness. However, some subscales present suboptimal internal consistency, reliability, and construct validity.
