RESUMEN

OBJECTIVE: This study aimed to develop and validate a questionnaire to assess changes in dietary behaviors among school children in Jordan during the COVID-19 pandemic. METHODS: A cross-sectional study used a convenience sample of 253 school-aged children from public schools across Jordan. The dietary and lifestyle behavior inventory (DLBI) was developed, incorporating cultural and regional dietary preferences. The questionnaire's validity and reliability were assessed using the content validity index (CVI) and Cronbach's alpha for internal consistency. Exploratory factor analysis (EFA) was conducted to evaluate the underlying factor structure. RESULTS: The DLBI demonstrated excellent content validity with a scale content validity index (S-CVI) of 0.997 and a high level of agreement among expert reviewers (total agreement = 116). Reliability analysis showed high internal consistency for dietary behavior scales, with Cronbach's alpha values exceeding 0.9 for fruit (0.869) and vegetable (0.916) consumption scales. Factor analysis revealed strong associations between dietary behavior variables, with factor loadings ranging from 0.688 to 0.889. The study identified significant reductions in physical activity levels among children, with an average Cronbach's alpha of 0.835 for physical activity-related items. The average time to complete the questionnaire was 15 minutes (SD = 5 minutes), with a completion rate of 45.6%. CONCLUSIONS: The validated DLBI is a robust tool for assessing changes in dietary behaviors among school-aged children in Jordan during the COVID-19 pandemic. The findings highlight significant dietary patterns and physical activity shifts, emphasizing the need for targeted nutritional interventions.

RESUMEN

BACKGROUND: Little is known about the disturbance in bodily experience (BE) following ventricular assist device (VAD) implantation. The level of disturbance in BE serves as an indicator of the status of the patients' adaptation process to the device. This process encompasses coping with both the more affective, psychological conflicts and the more cognitive, practical challenges of living with the VAD. To provide an economical screening tool for everyday clinical practice, we refined and validated a questionnaire on BE in VAD patients. METHODS: Seven specific items were derived from clinical experience and presented to 365 VAD patients (85% male; time since implantation: 3-36 months). The item structure was examined using factor analyses and probabilistic test theory. Discriminant validity and change sensitivity were determined in relation to associated psychometric instruments. RESULTS: Four items were found to constitute the unidimensional bodily experience scale (BE-S). Besides a high internal consistency of the scale (ω = 0.86), the RMSEA of >0.01 indicates a very good model fit. The BE-S has high convergent validity with related constructs (Hospital Anxiety and Depression Scale, Kansas City Cardiomyopathy Questionnaire). Change sensitivity analyses proved the BE-S alone to be significantly sensitive to the temporal dynamics of psychological adaptation processes following VAD implantation. CONCLUSION: The BE-S constitutes a valid and economical tool for clinical practice to assess patients' disturbance in BE after VAD implantation. It is a valuable tool for identifying patients with difficulties in adapting to the VAD. Subsequently, it enables early and focused therapeutic support for these patients at risk.

RESUMEN

Background: The present study was conducted with the aim of designing and validating questionnaires for evaluating the public health students' knowledge, performance, and satisfaction (KPS) in the course of educational technology. Methods: The present study was conducted with qualitative-quantitative approach. Qualitative stage was done based on experts' opinion and related articles and questionnaires for developing, designing, and validating the tools. For validating the tools, face validity and content validity was done based on the opinion of the 10 expert panel. In quantitative stage, all initial validated tools were implemented on 50 students of public health for determining the reliability. The reliability of the tools was calculated using the internal consistency method of the items with Cronbach's ⍺ coefficient, and Kuder-Richardson. All analyses were conducted using SPSS-19 software. Results: In the field of qualitative research, an assessment tool consisting of 20 four-option questions was designed. The content validity of this tool was confirmed based on the opinions of 10 educational experts, with CVI Total = 0.862 and CVR = 0.885. Additionally, the reliability of the tool was validated through testing on 50 public health students, resulting in a reliability coefficient of r = 0.780. Furthermore, for performance evaluation, four assessment tools each comprising 20 questions (totaling 80 questions) were designed. The validity values for these tools in the areas of PowerPoint (CVI = 0.981, CVR = 0.960), pamphlet (CVI = 0.866, CVR = 0.877), poster (CVI = 0.871, CVR = 0.906), role-playing (CVI = 0.871, CVR = 0.980), and the reliability of the tools with Cronbach's ⍺ r > 0.80 were confirmed. In the satisfaction assessment section, a researcher-made questionnaire consisting of 18 questions across seven domains was designed, with confirmed content validity (CVI = 0.949, CVR = 0.861) and reliability (r = 0.928). Conclusions: It seems that this tool can be used to measure the KPS of students from the educational technology course of the health field and similar fields.

RESUMEN

The escalation of global obesity is driving research to understand environmental influences on this process, particularly during vulnerable developmental stages such as childhood and adolescence. Efforts include the development of various structured data collection tools. We aimed to adapt a series of previously validated questionnaires from the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE), the Child Feeding Questionnaire, and elements from the World Health Organization Childhood Obesity Surveillance Initiative (COSI) in order to assess local lifestyle patterns among Romanian high school students and their families that may predispose them to obesity. To this goal, an expert committee was formed as part of a research partnership to oversee the questionnaire's translation and adaptation. It consisted of education and school management specialists, clinical research professionals, language experts, and public health experts. The adapted questionnaires were then applied to 114 students enrolled in the 9th and 10th grades attending a high school situated in Sibiu, and their parents. The variables measured were investigated for correlations with overweight and obesity and, as a secondary objective, academic performance. The study revealed several critical findings, including suboptimal sleep durations and physical activity levels among students, a significant amount of screen time, and correlations between weight status and physical activity, sedentary time, and maternal weight status and education levels. The adapted questionnaires proved to be effective tools in capturing the multifaceted factors implicated in adolescent obesity, providing a foundation for targeted interventions and broader public health strategies to address this issue.

RESUMEN

Introduction: Teaching professionalism is a fundamental aspect of medical undergraduate education, delivering important domains of professional attitudes, ethics, and behaviors. The effects of educational interventions can be assessed by measuring the change in such domains, but validated assessment tools for these professionalism domains are lacking. In this study, we constructed and conducted expert validation of a modified theory of planned behavior (TPB) questionnaire to assess changes in professional behaviors (PBs) in medical students. Methods: To validate that, we modified an existing TPB questionnaire, and an 18-item questionnaire was subjected to expert panel evaluation using the content validation method. The clarity and relevance of items were assessed using a four-point rating scale (i.e., 1 = not relevant to 4 = highly relevant). Ratings of experts and free-text comments were analyzed. Quantitative evaluation of relevance and clarity was undertaken through analyses of the Item-level Content Validity Index (I-CVI) and Scale-level Content Validity Index (S-CVI). A qualitative assessment of the comments of experts was conducted to refine items, any disagreements were discussed, and a consensus decision was developed among authors for item changes. Results: Quantitative evaluation of the Item-level Content Validity Index (I-CVI) scored 0.9-1 for relevance and 0.7-1 for clarity. Qualitative evaluation resulted in (i) changes to the wording of items (e.g., choices such as "worthless/worthwhile" were replaced with "not important/important"); and (ii) suggestion of the addition of social media in the construct of subjective norms. Discussion: The proposed tool exhibits content validity and can assess TPB constructs in professionalism education. This study of content validity may help to ensure the modified TPB questionnaire accurately measures the TPB constructs, ensuring its effectiveness in accurately measuring the TPB constructs for PB in diversified educational medical institutions.

RESUMEN

Eating in the absence of hunger (EAH) has been associated with overweight and obesity during childhood. The gold standard to assess this behavior is a laboratory-based protocol, but a questionnaire to assess EAH more efficiently in children and adolescents has been developed and validated in English. We assessed construct validity (structural and convergent validity) and reliability (internal consistency and temporal stability) of a French translation of the EAH Questionnaire for Children and Adolescents among French-Canadian youths. We recruited participants in Montreal (Canada) aged 7-15 years old, who completed the questionnaire and provided anthropometric data. We asked participants to complete the questionnaire a second time ∼4 weeks later. The questionnaire consists of 14 questions and 3 subscales that assess EAH due to negative affect, fatigue/boredom, and external cues. We performed an exploratory factor analysis to test the factor structure and we calculated Cronbach alpha coefficients and intra-class correlations to assess internal consistency and temporal stability, respectively. We assessed associations between EAH and BMI z-score using Pearson correlations. We included 196 participants (50% girls; mean (SD) 11.9 (2.3) years old) for the first completion and 153 for the second completion. The exploratory factor analysis generated the same three subscales as the original questionnaire: negative affect (α = 0.86; ICC = 0.78), fatigue/boredom (α = 0.75; ICC = 0.70), and external cues (α = 0.68; ICC = 0.54). Participant's BMI z-scores were positively associated with the average scores from the negative affect subscale (r = 0.19; ρ = 0.009). Our results suggest that this questionnaire has an adequate construct validity, internal consistency, and temporal stability.

RESUMEN

BACKGROUND: Social comparison, the process of evaluating one's characteristics in relation to others, influences individuals' self-perception and behavior. However, instruments are scarce for assessing social comparison in the medical setting. OBJECTIVES: Our aim was to develop and validate a new scale for assessing social comparison. MATERIALS AND METHODS: Seven statements were developed, encompassing the perceived normality of having rashes, the tendency to compare their situation with others, and the emotional response when seeing someone better or worse off than themselves. The instrument was piloted in 15 patients for readability and face validity, then prospectively validated using modern psychometric methods in 1,053 adult patients with eczema or psoriasis from three tertiary dermatological centers in Singapore. RESULTS: Of 1,053 adult patients, 802 (76.2%) had eczema, and 251 (23.8%) had psoriasis. Exploratory factor analysis (using a 70% sample split) showed a single factor model comprising three questions (Eigenvalue: 1.4). Confirmatory factor analysis with the remaining 30% of the sample confirmed an excellent model fit. Cronbach's alpha was 0.7, and inter-item correlations ranged from 0.42 to 0.46. In the Rasch analysis, item fit statistics and item characteristic curves showed appropriate discrimination between response options, although reliability was suboptimal with a person separation reliability of 0.63. CONCLUSIONS: Comprising 3 questions, the newly derived social comparison scale showed acceptable psychometrics as a measure of social comparison for clinical and research purposes in dermatology. Its brief nature likely results from its brevity and applicability to conditions beyond eczema and psoriasis, which warrants further investigation.

RESUMEN

Over the last decade, there have been repeated calls to expand the operationalisation of food parenting practices. The conceptualisation and measurement of these practices has been based primarily on research with parent-child dyads. One unexplored dimension of food parenting pertains to the evaluation of practices specific to feeding siblings. This study describes the development and validation of the Feeding Siblings Questionnaire (FSQ) - a tool designed to measure practices in which siblings are positioned as mediators in parents' attempts to prompt or persuade a child to eat. Item development was guided by a conceptual model derived from mixed-methods research and refined through expert reviews and cognitive interviews. These interviews were conducted in two phases, where parents responded to the questionnaire primarily to test i) the readability and relevance of each item, and ii) its overall feasibility. The instrument was completed by 330 parents (96.1% mothers) in Australia with two children aged 2-5 years, and repeated by 133 parents (40.3%) two weeks later. Exploratory factor analysis was performed on baseline data. Internal consistency and test re-test reliability of the subsequent subscales were examined. Construct validity was assessed through comparisons with existing measures of food parenting practices and child eating behaviours. The final FSQ scale included 22 items, reflecting five food parenting practices: sibling competitiveness, active sibling influence, threatening unequal division of food, sibling role modelling, and vicarious operant conditioning. Internal consistency and test re-test reliability estimates were high, and there was some evidence of convergent construct validity. While its factor structure should be confirmed in a different sample, the FSQ offers a novel tool for assessing, monitoring, and evaluating feeding interactions beyond those confined to the parent-child dyad.

RESUMEN

The Psoriatic Arthritis Impact of Disease (PsAID-12) questionnaire, a recommended measure of patient-reported impact for psoriatic arthritis (PsA), was initially developed in Europe and may lack universal validity. Recognizing the need for a culturally appropriate tool for Arab patients, this study aimed to TranslAte, CulTurally adapt, and validate the PsAID in ArabIC (TACTIC). The PsAID-12 was translated into Arabic using a rigorous process of double translation, back-translation, and cognitive debriefing. The Arabic version was then validated through a study conducted in 13 Arab countries in 2022. Participants were consecutive literate adult patients diagnosed with PsA and fulfilling the CASPAR criteria. Collected data included PsAID-12, disease activity, and legacy patient-reported outcomes. Psychometric properties, such as internal consistency, construct validity, and test-retest reliability, were examined. Factors associated with high PsAID-12 total scores (> 4) were explored using multivariable binary logistic regression. A culturally adapted Arabic PsAID-12 questionnaire was achieved with minor rephrasing. The validation study included 554 patients from 13 countries (mean age 45 years, 59% females), with a mean PsAID score of 3.86 (SD 2.33). The Arabic PsAID-12 demonstrated excellent internal consistency (Cronbach's α = 0.95), and correlations with other measures ranged from 0.63 to 0.78. Test-retest reliability (N = 138 patients) was substantial (intraclass correlation coefficient, ICC 0.90 [0.86-0.93]; Cohen's kappa 0.80). Factors associated with a high PsAID score were disability (odds ratio, OR 3.15 [2.03-4.89]), depression (OR 1.56 [1.35-1.81]), widespread pain (OR 1.31 [1.12-1.53]), and disease activity (OR 1.29 [1.13-1.47]). Pain and fatigue were identified as the most impactful PsAID-12 domains for PsA patients. The Arabic PsAID is a valid and reliable measure that reflects the priorities of patients with PsA. PsAID scores correlated with disease activity and legacy outcome measures, as expected, indicating PsAID is a consistent measure of PsA impact across cultures. These findings highlight the potential of the Arabic PsAID in improving the care provided to Arabic-speaking patients worldwide.

RESUMEN

Objective: In Germany, only a few standardized evaluation tools for assessing the usability of mobile Health apps exist so far. This study aimed to translate and validate the English patient version for standalone apps of the mHealth App Usability Questionnaire (MAUQ) into a German version. Methods: Following scientific guidelines for translation and cross-cultural adaptation, the patient version for standalone apps was forward and back-translated from English into German by an expert panel. In total, 53 participants who were recruited as part of the beta testing process of the recently developed mHealth app HerzFit, answered the questions of the German version of the MAUQ (GER-MAUQ) and the System Usability Scale. Subsequently, a descriptive as well as a psychometric analysis was performed to test validity and reliability. Results: After conducting three cognitive interviews, five items were modified. The values for Cronbach alpha for the entire questionnaire and the three subscales (0.966, 0.814, 0.910, and 0.909) indicate strong internal consistency. The correlation analysis revealed that the scores of the GER-MAUQ, the subscales and the SUS were strongly correlated with each other. The correlation coefficient of the SUS and the GER-MAUQ overall score was r = 0.854, P < 0.001 and the coefficients of the subscales and the SUS were r = 0.642, P < 0.001; r = 0.866, P < 0.001 and r = 0.643, P < 0.001. Conclusions: We have developed a novel German version of the MAUQ and demonstrated it as a reliable and valid measurement tool for assessing the usability of standalone mHealth apps from the patients' perspective. The GER-MAUQ allows a new form of standardized assessment of usability of mHealth apps for patients with cardiovascular disease in Germany. Further research with a larger sample and other samples is recommended.

RESUMEN

CONTEXT: Despite the potential benefits and the desire for end-of-life communication, it rarely occurs in the familial context. Relatives play a significant role in the communication process; thus, it is crucial to understand the difficulties that they face. OBJECTIVES: To develop and evaluate the relatives' version of the Difficulties in End-of-Life Discussions - Family Inventory (DEOLD-FI-r) regarding its factor structure, reliability and validity. METHODS: Relatives of patients with advanced cancer were recruited in a German hospital. The factor structure of the questionnaire was explored. Construct validity was examined through correlations between the DEOLD-FI-r and measures of avoidance of cancer communication, quality of life, distress, and experienced difficulty during end-of-life discussions. Additionally, we examined the group difference between those who had and had not engaged in the conversation. RESULTS: About 111 relatives completed the survey (mean age 55.5 years, 52% female). The final version of the DEOLD-FI-r contained 23 items (α = .92). The exploratory factor analysis resulted in three factors explaining 74% of the variance. Each factor described another dimension of potential communication barriers in end-of-life discussions: 1) Own emotional burden, 2) Relational and patient-related difficulties, 3) Negative attitudes. Construct validity was supported by correlations consistent with our hypotheses and less reported communication difficulty by those who had already talked about the end-of-life with their relative (t(106) = 5.38, P < .001, d = 0.8). CONCLUSION: The results indicate that the DEOLD-FI-r is a valid and reliable instrument for the systematic assessment of difficulties in family end-of-life communication. By focusing on relatives, it complements the already validated patient-version.

RESUMEN

Human dissections in the current medical curriculum are conducted using a checklist approach to prioritize the exposure of anatomical structures. In this setting, anatomy educators are labored to enhance their engagement during the dissection. To address this issue, we considered the current medical education pedagogies and identified a novel approach of studio-based learning (SBL) for application in a Human Dissection Workshop. This study aimed to (1) evaluate students' perceptions of SBL, (2) appraise the impact of SBL on anatomical knowledge learning, and (3) interpret the results of a validated questionnaire. Workshop participants were recruited from Year 2 medical students at the Chinese University of Hong Kong from the 2020 and 2021 cohorts. Fifty-one students participated in the workshop (N = 24 [2020], N = 27 [2021]), and 50 of them completed the postworkshop questionnaire rated on a 5-point Likert scale. Nineteen items were validated using a factor analysis. The interpretation of the questionnaire results demonstrated the different learning outcomes of the workshop, which included (1) enhancing students' knowledge and spatial understanding of anatomical structures, (2) strengthening students' appreciation of gross pathologies and clinical relevance, and (3) promoting higher-order thinking skills. To our knowledge, this is the first study to introduce SBL in medical education. The successful implementation of the workshop reflects the promising potential of SBL for enhancing human dissection and supplementing the medical curriculum.

RESUMEN

The objective of this study is to validate The Gambler’s Beliefs Questionnaire, a measure of gamblers’ cognitive distortions. The psychometric properties of the scale were analyzed with a Spanish sample of 515 participants aged from 16 and 24 years. Three scales related to pathological gambling (SOGS-RA and MAGS) and to social desirability were administered. A cross-sectional validation was performed, obtaining a scale with 21 items distributed in two independent factors (Luck/perseverance and Illusion of control). The internal consistency (α = .93) and test-retest reliability (r = .69) are adequate. GBQ scale scores correlate significantly with other measures of pathological gambling (SOGS: r = .35; MAGS: r = .40, both p ≤ .001). Higher levels of cognitive distortions are associated with a higher likelihood of being classified as a problem or at-risk gambler. GBQ scores are influenced by social desirability, although the effect sizes are small (r below .20). The GBQ is a useful instrument in the diagnosis and evaluation of the treatment of Spanish youths and adolescents with gambling problems. (AU)

El objetivo de este estudio es la validación española del “Gamblers Belief Questionnaire (GBQ)” que mide distorsiones cognitivas relacionadas con los problemas de juego. Se analizan las propiedades psicométricas de la escala en 515 jóvenes españoles, de 16 a 24 años. Se administraron tres escalas sobre juego patológico (GBQ, SOGS-RA y MAGS) y deseabilidad social. Se realizó una validación cruzada, obteniéndose una escala de 21 ítems con una estructura bifactorial (Suerte/Perseverancia e Ilusión de Control). La consistencia interna (α = ,93) y estabilidad temporal (r = ,69) de la escala son adecuadas. Las puntuaciones de la escala GBQ correlacionan de forma significativa con otras medidas de juego patológico (SOGS: r = ,35; MAGS: r = ,40, ambas p ≤ ,001). Un mayor nivel de distorsiones cognitivas se asocia a mayor probabilidad de ser clasificado como jugador con problemas o de riesgo. Las puntuaciones del GBQ están influenciadas por la deseabilidad social, aunque los tamaños del efecto son pequeños (r menores a ,20). El GBQ es un instrumento útil en el diagnóstico y evaluación de tratamientos de jóvenes y adolescentes españoles con problemas de juego. (AU)

RESUMEN

BACKGROUND: Prenatal distress encompasses a range of different emotions, worries, and experiences of stress. The Baby Preparation and Worry Scale (Baby-PAWS) was recently developed to target anticipatory worries during pregnancy about the postnatal period. However, the Baby-PAWS questionnaire was only examined in the United States of America, limiting the questionnaire's generalizability to different countries. To address this issue, we performed a psychometric evaluation of the questionnaire in a Dutch sample and examined associations between the Baby-PAWS questionnaire and established measures of maternal distress (i.e., EPDS, STAI, PRAQ-R) and infant temperament (i.e., IBQ-R). METHODS: Healthy pregnant women (N = 521) completed questionnaires during their third trimester and postnatally, including the Baby-PAWS and distress measures. A subsample of mothers (N = 194) also reported on infant temperament at 12 weeks postpartum. RESULTS: Exploratory factor analysis suggested a four-factor structure for the 16-item questionnaire in our Dutch sample, as compared to the expected three-factor structure found in the original psychometric evaluation with the American sample. The total Baby-PAWS score was related to pre-and postnatal depression, anxiety, stress, and specific scales of infant temperament. American women scored higher on the Baby-PAWS items than Dutch women. LIMITATIONS: Our participants had higher-than-average socioeconomic status, limiting the generalizability of the findings. CONCLUSION: The current analyses indicate good validity of the Baby-PAWS in a Dutch sample. Furthermore, our results highlight cross-cultural differences in perinatal mental health and show the importance of examining instrument structure of context-dependent constructs, such as prenatal worries.

RESUMEN

BACKGROUND: The World Health Organization characterizes infertility as a disease since 2009; however, in many countries, reproductive health is not prioritized. Characterizing a target population and knowing the barriers to accessing reproductive care may allow for a broadening of the discussion on how to provide equal opportunities. The objective of this study was to develop and validate a questionnaire that seeks to identify socioeconomic and cultural characteristics of Brazilian infertile couples to open the discussion on the principle of fair access to health. METHODS: (1) literature review in the main databases, (2) questionnaire elaboration by researchers within the areas of human reproduction and bioethics, concerned with content adequacy and comprehension, using the Google Forms online platform, (3) pilot study - the questionnaire was applied to 54 couples, over 18 years of age, that were seeking treatment for infertility and accepted to participate in the study and (4) statistical analysis - for continuous numerical variables, mean, standard deviation and 95% CI of the means were presented. For discrete numerical variables, median, interquartile range, minimum and maximum were presented. RESULTS: Forty-four questionnaires were fully completed and with adequate answers. The questionnaire proved to be objective and easy to understand. It was possible to obtain information on education, race of the couple, the impact of infertility on the couple's life, socioeconomic conditions, and the main difficulties in accessing medical care for treatment of infertility. CONCLUSION: The questionnaire proved to be feasible in collecting appropriate information to characterize a target population and the only limitation was that there was no academic expert evaluation prior to the pilot test.

RESUMEN

BACKGROUND: Good usability is important for the adoption and continued use of mobile health (mHealth) apps. In particular, high usability can support intuitive use by patients, which improves compliance and increases the app's effectiveness. However, many usability studies do not use adequate tools to measure perceived usability. The mHealth App Usability Questionnaire (MAUQ) was developed specifically for end users in a medical context. MAUQ is a relatively new but increasingly used questionnaire to evaluate mHealth apps, but it is not yet available in German. OBJECTIVE: This study aims to translate MAUQ into German and determine its internal consistency, reliability, and construct validity. METHODS: This validation study was conducted as part of a usability evaluation project for an mHealth app used as a therapy support tool during breast cancer chemotherapy. MAUQ was translated into German through a rigorous forward-backward translation process, ensuring semantic and conceptual equivalence. Patient responses to MAUQ and System Usability Scale (SUS) were analyzed for validation. Descriptive analysis was performed for the MAUQ subscales and SUS standard scores. Significance tests and correlation coefficients assessed the relationship between the SUS and MAUQ results, confirming construct validity. Internal consistency was assessed for item reliability and consistency in measuring the target construct. Free-text questions assessed translation comprehensibility, with responses analyzed descriptively and qualitatively using content analysis. RESULTS: In this study, 133 participants responded to the questionnaire, and the validation analysis showed substantially positive correlations between the overall MAUQ score and its subscales: ease of use (r=0.56), interface and satisfaction (r=0.75), and usefulness (r=0.83). These findings support the construct validity of MAUQ and emphasize the importance of these subscales in assessing the usability of the Enable app. The correlation coefficients ranging from 0.39 to 0.68 for the items further validate the questionnaire by aligning with the overall score and capturing the intended concept. The high internal consistency reliability of MAUQ (Cronbach α=.81) and its subscales further enhances the instrument's robustness in accurately evaluating the usability of mHealth apps. CONCLUSIONS: We successfully validated the German translation of the MAUQ for stand-alone apps using a standardized approach in a cohort of patients with breast cancer. In our validation study, MAUQ exhibited strong internal consistency reliability (Cronbach α=.81) across its subscales, indicating reliable and consistent measurement. Furthermore, a significant positive correlation (P<.001) was found between the subscales and the overall score, supporting their consistent measurement of the intended construct. Therefore, MAUQ can be considered a reliable instrument for assessing the usability of mHealth apps among German-speaking adults. The availability of the German version of MAUQ will help other researchers in conducting usability studies of mHealth apps in German-speaking cohorts and allow for international comparability of their results.

RESUMEN

Background: Workplace violence prevention initiatives are undeniably lacking in healthcare facilities. The aim of this study was to validate a newly developed questionnaire and assess employers' perceptions and practices towards workplace violence prevention at healthcare facilities. Methods: A cross-sectional study was conducted from October 2021 to November 2021 by recruiting 333 employers at healthcare facilities in Kelantan, Malaysia. The original draft of the Malay version of the questionnaire comprised 62 items constructed under two domains (perception and practice). A confirmatory factor analysis was conducted to evaluate construct validity and internal consistency using R software. Results: The final model for the perception and practice domain of the questionnaire consisted of 13 factors and 56 items. The factor loadings for all items were above 0.6. The fit indices used for confirmatory factor analysis in the final model were as follows: χ2 = 2092.6 (P < 0.001), standardised root mean squared residual (SRMR) = 0.053, root mean square error of approximation (RMSEA) = 0.042, comparative fit index (CFI) = 0.928 and Tucker Lewis index (TLI) = 0.920. The construct reliability for all factors was reliable, with Raykov's rho coefficients above 0.70. Conclusion: The newly developed questionnaire demonstrated excellent psychometric properties and adequate validity and reliability, confirming that this instrument is reliable and valuable for evaluating employers' perceptions and practices towards workplace violence prevention at healthcare facilities.

RESUMEN

Sense of agency refers to the experience of controlling one's actions and through them events in the outside world. General agency beliefs can be measured with the Sense of Agency Scale (SoAS), which consists of the sense of positive agency subscale (i.e., feeling of being in control over one's own body, mind, and environment) and the sense of negative agency subscale (i.e., feeling existentially helpless). The aim of the present study was to validate a German version of the SoAS. Using factor analyzes, we replicated the two-factor structure of the original version of the SoAS. Further, the German SoAS showed good model fits, good internal consistency, and moderate test-retest reliability. Construct validity was supported by significant low to moderate correlations of the German SoAS with other conceptually similar, but still distinct constructs such as general self-efficacy. Additionally, the German SoAS has an incremental value in explaining variance in the extent of subclinical symptoms of schizotypal personality disorder that goes beyond variance explained by constructs that are conceptually similar to sense of agency. Taken together, the results indicate that the German SoAS is a valid and suitable instrument to assess one's general agency beliefs.

RESUMEN

BACKGROUND: Effective communication is an essential component of high-quality nursing care. Health literacy, the ability to access, describe, evaluate and apply health information to make informed decisions, is an important component of effective communication in nursing. Nurses, including student nurses, with good levels of health literacy (HL) are well positioned to communicate reliable public health-related information effectively, at times like the COVID-19 global pandemic. At this time, many nursing students have been at the frontline of patient education, as such, it would be expected that they have high levels of HL. However, it has been suggested that there is the need to improve HL levels in nursing students. AIMS: The aim of this study was to analyse the structure of item response of a back translated Chinese version of the COVID-HLS-Q22 questionnaire and to assess the coronavirus-related HLof Chinese speaking nursing students in Hong Kong using the COVID-HLS-Q22-CN. METHODS: A cross-sectional study of 97 undergraduate nursing students was conducted using two self-reported questionnaires. The HLS-EU-16 scale, with face validity already established, was used to assess scale equivalence Using a cross-over study approach, student participants were randomly assigned in sequential order. The validation process was performed in five phases: direct translation, translation synthesis, back translation, consolidation with experts, and testing with the students. The intended outcome of this study will be a formally tested model of the Chinese version of the COVID-HLS-Q22-CN, that can be replicated in Chinese population. RESULTS: Factorial equivalence was present across language versions in both questionnaires. Internal consistency was excellent for COVID-HLS-Q22-CN (coefficient alpha for Chinese version of questionnaire, 0.957 and English version, 0.953). This suggested that the four subscale are stable across the two questionnaires. CONCLUSION: The COVID-HLS-Q22-CN has proven to be a feasible and reliable tool in the assessment of Hong Kong based Chinese speaking nursing students. The emergence of issues around COVID-related HL further highlights the need to include the teaching of critical health literacy skills within nurse education, preparing the healthcare professionals of the future for public health emergencies.

RESUMEN

AIM: To translate the orthodontic experience questionnaire into Malayalam, an Indian language, and assess its validity and reliability in the Kerala population. MATERIALS AND METHODS: The original questionnaire, which was developed in English, was translated into Malayalam. Face validity was assessed, and minor changes were made, followed by a content validity assessment by an expert panel. The final version was given to 324 patients who marked their responses on a Likert scale. Internal consistency reliability was tested using Cronbach's alpha, and test-retest reliability was tested using the intraclass correlation coefficient. Principal component factor analysis was performed to regroup the valid items. RESULTS: The principal component factor analysis revealed three domains. Reliability assessed by Cronbach's alpha of the whole questionnaire was 0.799, and that of the three domains was 0.73, 0.71, and 0.71, respectively. The test-retest reliability was found to be good (0.798). CONCLUSION: The Malayalam version of the orthodontic experience questionnaire was found to be content valid with good reliability. To obtain a successful treatment result, an orthodontist must be aware of these and this questionnaire, with adequate validity and reliability, has been designed to achieve this in the Malayalam-speaking population.
