Translation and Validation of Digital Competence Indicators in Greek for Health Professionals: A Cross-Sectional Study.

it is widely accepted that living in the digital transformation era, the need to develop and update new professional skills and tools in health sectors is crucially important. Therefore, this study aimed to explore the reliability and validity of the Digital Competence Indicators tool in assessing the digital skills of Greek health professionals. in this cross-sectional study, 494 health professionals, including doctors (175) and registered nurses (319) working in four Greek hospitals were recruited and willingly participated using a convenience-sampling method. The original framework of Digital Competence Indicators was translated from English to Greek based on guidelines for cross-cultural adaptation of questionnaires. The validity of the tool was explored using confirmatory factor analysis (CFA) to verify the fit of the model using inductive techniques. The instrument reliability was confirmed using Cronbach's alpha (α) and McDonald's Omega coefficients. the reliability was estimated at 0.826 (Cronbach's-α) and 0.850 (McDonald's Omega-ω). The indicators of CFA were all calculated within an ideal range of acceptance. Specifically, the CFA comparative fit index produced the following adjustment indices: x2/df = 1.152 (p = 0.037), CFI = 0.997, Lewis index (TLI) = 0.966, and root mean square error of approximation (RMSEA) = 0.018. The present study demonstrated that the Digital Competence Indicator instrument has high reliability, internal consistency, and construct validity and, therefore, it is suitable for measuring digital skills of health professionals.

Validation of the Greek version of Mother's Autonomy in Decision Making (MADM) scale.

Ensuring expectant mothers have the capacity to make well-informed decisions regarding their prenatal care, encompassing medical interventions, and birthing preferences are crucial for fostering favorable health outcomes for both mother and newborn. The Mother's Autonomy in Decision Making (MADM) scale serves as a commonly utilized tool for evaluating the autonomy of pregnant women in the decision-making processes related to prenatal care and childbirth. The aim of this study is to validate the MADM scale in women who had at least one home childbirth experience in Greece. A retrospective online survey collected data from Greek women with home childbirth experience (January 2010 - December 2023). We utilized a self-administered questionnaire and the Greek version of the MADM scale. The study included 162 women, predominantly of Greek nationality (94.4%) and residing in Attica (54%). The MADM scale showed a median score of 38. The confirmatory factor analysis indicated acceptable fit and reliability (comparative fit index, CFI=0.92; Tucker-Lewis index, TLI=0.91; root mean square error of approximation, RMSEA=0.07; Cronbach's α=0.92). Age correlated weakly negatively with the MADM scale score (Spearman's rho= -0.166, p=0.035). Additionally, women attending antenatal preparation courses with a midwife before their first home birth had higher MADM scores (median 39 vs 35, p=0.037). The study underscores the importance of the MADM scale, demonstrating its reliability and validity for women living in Greece. Younger age and attending antenatal preparation courses with a midwife were associated with higher MADM scores, highlighting education's role in maternal autonomy.

Adventitious Error and Its Implications for Testing Relations Between Variables and for Composite Measurement Outcomes.

Wu and Browne (Psychometrika 80(3):571-600, 2015. https://doi.org/10.1007/s11336-015-9451-3 ; henceforth W &B) introduced the notion of adventitious error to explicitly take into account approximate goodness of fit of covariance structure models (CSMs). Adventitious error supposes that observed covariance matrices are not directly sampled from a theoretical population covariance matrix but from an operational population covariance matrix. This operational matrix is randomly distorted from the theoretical matrix due to differences in study implementations. W &B showed how adventitious error is linked to the root mean square error of approximation (RMSEA) and how the standard errors (SEs) of parameter estimates are augmented. Our contribution is to consider adventitious error as a general phenomenon and to illustrate its consequences. Using simulations, we illustrate that its impact on SEs can be generalized to pairwise relations between variables beyond the CSM context. Using derivations, we conjecture that heterogeneity of effect sizes across studies and overestimation of statistical power can both be interpreted as stemming from adventitious error. We also show that adventitious error, if it occurs, has an impact on the uncertainty of composite measurement outcomes such as factor scores and summed scores. The results of a simulation study show that the impact on measurement uncertainty is rather small although larger for factor scores than for summed scores. Adventitious error is an assumption about the data generating mechanism; the notion offers a statistical framework for understanding a broad range of phenomena, including approximate fit, varying research findings, heterogeneity of effects, and overestimates of power.

Measurement properties of the Regular Physical Exercise Adherence Scale (REPEAS) in individuals with chronic pain

ObjectiveTo examine the measurement properties of the Regular Physical Exercise Adherence Scale (REPEAS) in Brazilians with chronic pain.MethodsCross-sectional and longitudinal design (washout period for reliability). The study was conducted in two Brazilian states, Maranhão and São Paulo, and included Brazilian adults, irregular exercisers, former exercisers or non-exercise practitioners, aged 18 to 59 years and with chronic pain. The instruments used in this study were: the REPEAS, the Numerical Pain Rating Scale (NPRS), the Baecke Habitual Physical Activity Questionnaire (BHPAQ), the Pain Self-Efficacy Questionnaire (PSEQ), and the Roland-Morris Disability Questionnaire for general pain (RMDQ-g). The evaluation focused on structural validity, construct validity, reliability (with standard error of measurement and minimum detectable change), internal consistency, and floor and ceiling effects.ResultsThe two-dimensional structure was tested through confirmatory factor analysis, which resulted in adequate fit indeces: chi-square values/degrees of freedom = 1.541, Tucker-Lewis Index = 0.966, comparative fit index = 0.974, root mean square error of approximation = 0.074, and standardized root mean square residual = 0.068. Additionally, satisfactory factor loadings (> 0.40) were obtained. Test-retest reliability and internal consistency were adequate for the environmental factors domain (intraclass correlation coefficient [ICC] = 0.79, Cronbach’s alpha = 0.88) and the personal factors domain (ICC = 0.97, Cronbach’s alpha = 0.93). In hypothesis testing for construct validity, we observed a significant correlation with magnitude below 0.30 of the environmental factors domain of the REPEAS with RMDQ-g, PSEQ and sport domain of the BHPAQ. For the personal factors domain, we observed a significant correlation with a magnitude of 0.30 to 0.50 with RMDQ-g, PSEQ, and sport domain of the BHPAQ, and below 0.30 with leisure domain of the BHPAQ. No floor or ceiling effects were found for the REPEAS domains.ConclusionThe REPEAS is a valid instrument with a two-dimensional internal structure consisting of 12 items. It has a reliable construct and is suitable for use in the clinical and epidemiological context for adults with chronic pain in Brazil.

Reliability and Validity of the Health-Promoting Lifestyle Profile II Spanish Version in University Students.

The purpose of this study was to assess the reliability and validity of the Spanish version of the Health Promoting Lifestyle Profile II (HPLP-II) scale in Colombian university students. This was a methodological study to verify reliability and construct validity. A total of 763 undergraduate university students in Cali, Colombia, agreed to participate in the study by filling out a form that included information on sociodemographic characteristics and the HPLP-II scale Spanish version. Data were collected between February and June 2021. To determine construct validity, a confirmatory factor analysis was performed, and internal consistency was determined through Cronbach's alpha. The confirmatory factor analysis of the proposed theoretical model showed that the goodness-of-fit indices of the scale demonstrated an acceptable level of validity nearing an excellent level of fit (χ2 = 7168.98; gl = 1268; p < 0.001; root mean square error of approximation = 0.08; normed fit index, adjusted goodness-of-fit index = 0.95). Cronbach's alpha coefficient of the scale was 0.94, and the subscales ranged from 0.68 to 0.89. The HPLP-II Spanish version is a valid and reliable instrument to assess the health-promoting lifestyle profile of university students.

Developing an Emotional Labor Scale for Employees in the Service Industry

Purpose: This research aims to develop an emotional labor scale and examine the consistency of the emotional labor measurement model with empirical data. The study focuses on individuals with long-term work experience and incorporates cross-cultural perspectives to address gaps in current research. Additionally, it seeks to create a standardized model for measuring and evaluating emotional labor that is applicable to contemporary work environments. Methodology: The population is front-service employees of hotels in Chonburi Province, and the sample consists of 280 front-service employees of hotels in Pattaya City, Chonburi Province. The research methodology for developing the emotional labor scale in this phase is quantitative research, using confirmatory factor analysis to examine the consistency of the emotional labor measurement model. Findings: The results of the model fit analysis and quality assessment of the CFA model found that the RMSEA (Root Mean Square Error of Approximation) was 0.217, indicating a lack of fit between the model and data. The CFI (Comparative Fit Index) was 0.591. The TLI (Tucker-Lewis Index) was 0.442. Finally, the IFI (Incremental Fit Index) was 0.595. Based on the presented indices, this model has a poor fit with the data. The RMSEA, CFI, TLI, and IFI values are lower than the recommended criteria, indicating a discrepancy between the model and data. Unique Contribution to Theory, Policy and Practice: These findings suggest that current emotional labor measurement models may not accurately capture the experiences of workers across different cultures and with varying lengths of work experience. Policymakers and organizations should consider developing more nuanced and culturally sensitive approaches to assess and manage emotional labor in the workplace. This could involve creating tailored training programs, revising performance evaluation metrics, and implementing supportive policies that acknowledge the complexity of emotional labor across diverse work environments.

Identifying neurofunctional domains across substance use disorders

ABSTRACT Background: Substance use disorders (SUDs) are heterogeneous across multiple functional domains. Various frameworks posit that domains (e.g., executive function) contribute to the persistence of SUDs; however, the domains identified in different studies vary. Objectives: We used factor analysis to identify the underlying latent domains present in a large sample (N = 5,244, 55.8% male) with a variety of SUDs to yield findings more generalizable than studies with a narrower focus. Method: Participants (1,384 controls and 3,860 participants with one or more SUDs including alcohol, cocaine, cannabis, and/or opioid use disorders) completed the Semi-Structured Assessment for Drug Dependence and Alcoholism, the NEO Personality Inventory, and the Wisconsin Card Sorting Test. Exploratory factor analysis (EFA) and fit indices (root mean-squared error of approximation (RMSEA), Comparative Fit Index (CFI), and Tucker-Lewis Index (TLI)) were used to examine different latent variable models. A multiple indicators, multiple causes (MIMIC) approach-tested associations of the latent variables with sociodemographics, substance use, and a history of abuse/neglect. Results: A six-factor model (predominant alcohol, predominant cocaine, predominant opioid, externalizing, personality, and executive function) provided the best fit [RMSEA = 0.063 (90% CI 0.060, 0.066), CFI = 0.98, TLI = 0.96]. All factors were moderately correlated (coefficient = 0.25–0.55, p < .05) with the exception of executive function. MIMIC analysis revealed different patterns of associations (all p < .0001) with sociodemographics, substance use, and a history of abuse/neglect among the factors. Conclusions: The domains identified, particularly executive function, were parallel to those observed previously. These factors underscore the heterogeneous nature of SUDs and may be useful in developing more targeted clinical interventions.

Quality and customer loyalty in the port services of Manzanillo

The customs industry, particularly within the Mexican context, plays a significant role both domestically and internationally, owing to its contribution to the global economy. With the expansion and standardization of customs clearance services, there has emerged a necessity for providers of these services to seek customer loyalty. Grounded in the principles of quality, the study examines the elements of the SERVQUAL model: tangibles, reliability, responsiveness, assurance, and empathy. Goals:The aim of the study was to extend the SERVQUAL model by incorporating customer attitude as an additional component within the three primary dimensions for measuring service quality. Methodology: A survey was employed to gather data from 100 customs brokerage firms through simple random sampling. Given the utilization of structural equation modeling (SEM) methodology to assess the theoretical model, Partial Least Squares (PLS) analysis technique was applied using Smart PLS 3.3.0 software. The findings indicated that the extended model had a significant impact on both customer satisfaction and loyalty within the customs facilities of Manzanillo, Colima. The coefficients of determination were 61.5% for customer satisfaction and 54% for customer loyalty, with a root mean square error of approximation (SRMR) of 0.065, confirming the model's predictive validity. Contributions: Customs facilities should focus their strategies on addressing issues that may be impacting service quality, particularly concerning sensitivity, empathy, and reliability factors, as these have a moderate level of influence on quality determination, according to customs agencies' perceptions. Regarding the inherent limitations of online surveys and their application in specialized groups, it is crucial to expand the research to include other clients of the customs facility.

Validation of Kannada Version of the Amsterdam Preoperative Anxiety and Information Scale (APAIS).

Preoperative anxiety is a complex and subjective phenomenon, most commonly observed in patients posted for elective surgery. The Amsterdam Preoperative Anxiety Information Scale (APAIS) has been widely used in preoperative settings to measure anxiety quickly. This study aimed to translate the APAIS into Kannada and to evaluate its psychometric properties. The study involved forward and backward translation of APAIS into Kannada followed by a cognitive interview of 10 patients by clinical psychologist to confirm the correct translation. The translated version was then administered to 240 patients who were posted for elective surgery along with the Visual Analogue Scale for Anxiety (VAS-A). Reliability and internal consistency were assessed by calculating Cronbach's alpha. Construct validity was assessed by principal component analysis and confirmatory factor analysis. Criteria validity was assessed by evaluating the correlation between APAIS and VAS-A. The Kannada-translated version of APAIS was completed by 224 patients posted for elective surgery. Cronbach's alpha was 0.82 and 0.83 for anxiety and need for information items, respectively. Root mean square error of approximation (RMSEA), comparative fit index (CFI),and Tucker-Lewis index (TLI) were 0.07, 0.98, and 0.96, respectively, for three-factor model, indicating it to be best fit for Kannada version of APAIS. The Kannada version of APAIS is a valid and reliable tool for measuring preoperative anxiety in patients undergoing elective surgery.

Racism in obstetric care: a psychometric study of the Gendered Racial Microaggressions Scale among Global Majority birthing people in obstetric contexts

In the United States, maternal health inequities disproportionately affect Global Majority (e.g., Asian, Black, and Hispanic) populations. Despite a substantial body of research underscoring the influence of racism on these inequities, little research has examined how experiences of gendered racial microaggressions during pregnancy and birth impact racially and ethnically diverse Global Majority pregnant and birthing people in obstetric hospital settings. We evaluated the psychometric properties of an adapted version of Lewis & Neville’s Gendered Racial Microaggressions Scale, using data collected from 417 Global Majority birthing people. Findings from our study indicate that our adapted GRMS is a valid tool for assessing the experiences of gendered racial microaggressions in hospital-based obstetric care settings among Global Majority pregnant and birthing people whose preferred languages are English or Spanish. Item Response Theory (IRT) analysis demonstrated high construct validity of the adapted GRMS scale (Root Mean Square Error of Approximation = 0.1089 (95% CI 0.0921, 0.1263), Comparative Fit Index = 0.977, Standardized Root Mean Square Residual = 0.075, log-likelihood c2 = -85.6, df = 8). IRT analyses demonstrated that the unidimensional model was preferred to the bi-dimensional model as it was more interpretable, had lower AIC and BIC, and all items had large discrimination parameters onto a single factor (all discrimination parameters > 3.0). Given that we found similar response profiles among Black and Hispanic respondents, our Differential Item Functioning analyses support validity among Black, Hispanic, and Spanish-speaking birthing people. Inter-item correlations demonstrated adequate scale reliability, α = 0.97, and empirical reliability = 0.67. Pearsons correlations was used to assess the criterion validity of our adapted scale. Our scale’s total score was significantly and positively related to postpartum depression and anxiety. Researchers and practitioners should seek to address instances of gendered racial microaggressions in obstetric settings, as they are manifestations of systemic and interpersonal racism, and impact postpartum health.

Development and its reliability and validity of the Knowledge, Attitude and Practice Scale for Informal Caregivers of Pressure Injury Patients.

There is a lack of scientifically validated tools to measure the knowledge attitude and practice (KAP) of informal caregivers for patients with pressure injury (PI). This study aims to develop a KAP Scale for Informal Caregivers of PI Patients and to evaluate its reliability and validity. Based on the KAP theory framework and relevant literature, an initial pool of items was created through expert brainstorming sessions. The initial scale was formed after a Delphi expert consultation and a preliminary survey. From April to October 2023, a convenient sample of informal caregivers for PI patients was recruited from an inpatient department of the Third Xiangya Hospital of Central South University, as well as its associated community and nursing homes. The first round included 186 participants, and the second round included 213 participants, who were used for item analysis and reliability and validity testing. After a 3-week interval, 20 participants from the initial group were randomly selected for a retest to assess the test-retest reliability of the scale. The KAP Scale for informal caregivers of PI patients consists of 3 dimensions with 19 items. The overall internal consistency (Cronbach's α) of the scale was 0.916. The item-level content validity index (I-CVI) ranged from 0.826 to 1.000, and the scale level-content validity index/average (S-CVI/Ave) was 0.94. Exploratory factor analysis extracted 3 common factors, accounting for 64.643% of the total variance. Confirmatory factor analysis showed that the model fit the data well, with χ2/df=2.54, root mean square error of approximation (RMSEA)=0.085, comparative fit index (CFI)=0.920, and standardized root mean square residual (SRMR)=0.059. The KAP scale for informal caregivers of PI patients demonstrates good reliability and validity and can be used to assess the KAP levels of informal caregivers regarding PI.

Psychometric Properties of the Malay Version of the Coach-Athlete Relationship Questionnaire for Coaches and Athletes.

In the world of sports, motivation is an essential concept that can affect the sporting performance of athletes and help them accomplish their goals. The coach is regarded as an important individual with the ability to significantly influence the athlete's motivation. To assess the impact of the coach-athlete relationship on motivation, the objective of this study was to evaluate the psychometric properties of the Malay version of the Coach-Athlete Relationship Questionnaire (CART-Q) for coaches and athletes. A cross-sectional survey was conducted among the coaches and athletes in Malaysia. Data were collected using a convenience sampling approach over a 6-month period. The study was carried out in two phases using two independent samples of coaches and athletes to assess the construct validity and internal consistency of the Malay version of the CART-Q. The CART-Q consisted of 11 items measuring three constructs: i) closeness (four items), ii) commitment (three items) and iii) complementarity (four items). In phase 1, the subjects consisted of 211 coaches (21 years old-65 years old) from both sexes and from individual and team sports, ranging from levels 1 to 5. In phase 2, the subjects consisted of 362 athletes (12 years old-39 years old), also from both sexes and from individual and team sports. The statistical analyses performed included confirmatory factor analysis (CFA) to validate the translated version scale, composite reliability (CR), average variance extracted (AVE) and internal consistency (Cronbach's alpha). In phase 1, the sample of coaches, with 190 males (90.0%) and 21 females (10.0%), had a mean age of 38.6 (SD = 8.74) years old. The major sport type was archery (19.0%). The CFA revealed adequate fit indices with all 11 items retained (root mean square error of approximation [RMSEA] = 0.059, comparative fit index [CFI] = 0.964, Tucker and Lewis Index [TLI] = 0.950, standardised root mean square residual [SRMR] = 0.037). The CR values were closeness = 0.874, commitment = 0.566 and complementarity = 0.757. The AVE values were closeness = 0.357, commitment = 0.194 and complementarity = 0.275. The Cronbach's alpha values were closeness = 0.867, commitment = 0.553 and complementarity = 0.794. In phase 2, the sample of athletes, with 175 males (48.1%) and 189 females (51.9%), had a mean age of 20.2 (SD = 3.35) years old. The major sport type was archery (11.5%). The CFA revealed satisfactory fit indices with all 11 items retained (RMSEA = 0.092, CFI = 0.948, TLI = 0.924, SRMR =.038). The CR values were closeness = 0.893, commitment = 0.786 and complementarity = 0.949. The AVE values were closeness = 0.401, commitment = 0.253 and complementarity = 0.418. The Cronbach's alpha values were closeness = 0.900, commitment = 0.772 and complementarity = 0.900. Overall, the study findings supported the conclusion that the Malay version of the CART-Q has adequate psychometric properties to assess the perceptions of coaches and athletes regarding their relationship.

Subjective Cognitive Decline in Community-Dwelling Older Adults With Objectively Normal Cognition: Mediation by Depression and Instrumental Activities of Daily Living.

Subjective cognitive decline (SCD) refers to self-reported memory loss despite normal cognitive function and is considered a preclinical stage of Alzheimer's disease. This study aimed to examine the mediating effects of depression and Instrumental Activities of Daily Living (IADL) on the association between the scoring of Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) and Subjective Cognitive Decline Questionnaire (SCD-Q). A sample of 139 community-dwelling older adults aged 65-79 with normal cognitive function completed the SCD-Q, a comprehensive neuropsychological battery, and functional/psychiatric scales. We conducted 1) a correlation analysis between SCD-Q scores and other variables and 2) a path analysis to examine the mediating effects of depression and IADL on the relationship between CDR-SB and SCD-Q. CDR-SB was found to be indirectly associated with SCD-Q, with depressive symptoms mediating this relationship. However, no direct association was observed between SCD-Q and CDR-SB. Additionally, IADL was not associated with SCD-Q and did not mediate the relationship between CDR-SB and SCD-Q. The model fit was acceptable (minimum discrepancy function by degrees of freedom divided [CMIN/DF]=1.585, root mean square error of approximation [RMSEA]=0.065, comparative fit index [CFI]=0.955, Tucker-Lewis index [TLI]=0.939). Our results suggest that SCD-Q is influenced by depressive symptoms, but not by IADL. The role of depressive symptoms as a mediator between CDR-SB and SCD-Q indicates that psychological factors may contribute to the perception of SCD. Therefore, interventions targeting depression may mitigate the concerns associated with SCD and reduce feelings of worse performance compared to others of the same age group.

Model of dimensions and variables of corporate social responsibility updated through structural equations.

Corporate social responsibility (CSR) is a constantly evolving concept that reflects changes in society and the expectations of stakeholders in a process that leads companies to adapt to respond to new challenges and demands. Similarly, the theory and practice of CSR have moved from regulatory compliance to a more holistic approach that requires more sophisticated models that allow for a deeper understanding. Following the fact that companies now have access to a greater amount of information related to their social and environmental performance, as well as comparative data from other organizations, which is why it is necessary to have a management tool that allows collecting, process, and generating more accurate and meaningful metrics that more effectively reflect a company's impact on society. Consequently, the present work aims to identify a system of variables and dimensions representative of the management of organizations that allows the validation of a generic model of corporate social responsibility determined through factorial and structural modeling capable of reflecting more accurate and up-to-date dimensions and metrics of model variables and dimensions. To carry out the study, a sample of 667 middle and senior managers from medium and large companies in Guayas, Ecuador, were randomly contacted in their respective business contexts by trained interviewers. The data processing was carried out in stages. First, the exploratory factorial analysis method of the items was applied to form relevant factors. Then, the dimensions' structural modeling was formulated and ratified through the pertinent goodness-of-fit indices. The results determined a system of correlated factors whose items present estimators of commonality and high and significant factorial loads, excluding variables that did not exceed the sensitization criteria applied. Finally, a model made up of 15 factors and 66 variables ratified using the comparative adjustment indices, the chi-square likelihood ratio, and the mean square error of approximation is introduced, confirming the proposed corporate social responsibility model.

Psychosocial correlates of parents' willingness to vaccinate their children against COVID-19.

Public health guidance recommended that children who are 6 months or older be vaccinated against COVID-19 in June of 2022. In the U.S., 56% of children under 17 had not received the COVID-19 vaccination in 2023. We examine parents' willingness to vaccinate their children against COVID-19 using the theory of planned behavior in order to design effective strategies to promote vaccine uptake. The Philadelphia Community Engagement Alliance is part of an NIH community-engaged consortium focused on addressing COVID-19 disparities across the U.S. We surveyed 1,008 Philadelphia parents (mean age 36.86, SD 6.55; 42.3% racial/ethnic minorities) between September 2021 and February 2022, a period when guidance for child vaccination was anticipated. Structural Equation Modeling analysis examined associations between parental willingness and vaccine-related attitudes, norms, and perceived control. Covariates included parents' COVID-19 vaccination status, race/ethnicity, gender, and survey completion post-CDC pediatric COVID-19 vaccination guidelines. Subgroup analyses by race/ethnicity and gender were conducted. Our model demonstrated good fit (χ2 = 907.37, df = 419, p<0.001; comparative fit index [CFI] = 0.951; non-normed fit index [NNFI] = 0.946; root mean square error of approximation [RMSEA] = 0.034 with 95% CI = 0.030-0.038). Attitudes ([Formula: see text] = 0.447, p<0.001) and subjective norms ([Formula: see text] = 0.309, p = 0.002) were predictors of intention. Racial/ethnic minority parents exhibited weaker vaccination intentions ([Formula: see text] = -0.053, p = 0.028) than non-Hispanic White parents. Parents' attitudes and norms influence their vaccination intentions. Despite the survey predating widespread child vaccine availability, findings are pertinent given the need to increase and sustain pediatric vaccinations against COVID-19. Interventions promoting positive vaccine attitudes and prosocial norms are warranted. Tailored interventions and diverse communication strategies for parental subgroups may be useful to ensure comprehensive and effective vaccination initiatives.

Confirmation of the Unidimensionality of the Satisfaction and Recovery Index Among Those With Various Musculoskeletal Disorders.

Background A semistructured patient-reported outcome measure (PROM) wherein patients rate the importance of structured items and the magnitude of the psychometric properties to be investigated (e.g., disability and satisfaction) facilitates patient engagement in their treatment and patient-centered clinical practice. The Satisfaction and Recovery Index (SRI) is one such semistructured PROM that was originally developed to measure recovery from a whiplash injury. Exploratory factor analysis demonstrated a one-factor structure among ambulatory community-dwelling people with traumatic musculoskeletal injuries. However, a confirmatory factor analysis has not been conducted among patients with various musculoskeletal disorders, and the internal structure of the SRI has not been established yet. Thus, this study aimed to investigate the internal structure of the SRI among patients with diverse musculoskeletal disorders. Methodology An anonymous survey was performed for patients who were referred for physical therapy for musculoskeletal disorders at a local orthopedic clinic. A confirmatory factor analysis was conducted. The goodness-of-fit criteria were as follows: chi-square/degree of freedom < 3, goodness-of-fit index > 0.90, adjusted goodness-of-fit index > 0.95, and root mean square error of approximation < 0.08. Results Data from 217 participants were analyzed. All goodness-of-fit criteria were satisfied. Conclusion This study confirmed the acceptable internal structure of the SRI among patients with diverse musculoskeletal disorders.

Evaluating the Malay version of NIOSH WellBQ: A study on reliability and construct validity for enhanced workplace well-being assessment

This study aimed to validate the Worker Well-Being Questionnaire, originally developed by the US National Institute for Occupational Safety and Health, in the Malay language. The translation process involved an initial independent translation by a professional translator, followed by a comparison of translations to synthesize a unified version, which was subsequently back-translated. The back-translations were then reviewed by an expert committee to create a finalized questionnaire version. The results of this validation study indicate a high level of satisfaction, demonstrating an excellent fit with confirmatory factor analysis (CFI and TLI values ranging from 0.96 to 0.99) and a low root mean square error of approximation (RMSEA values ranging from 0.03 to 0.07). Moreover, the questionnaire exhibits sound internal consistency, with Cronbach’s alpha values exceeding 0.7, and the factor structures align with theoretical expectations. In conclusion, the Malay version of the questionnaire faithfully reproduces the original instrument, enabling a robust and efficient assessment of workers’ well.

A Chinese version of the Stroke Illness Perception Questionnaire-Revised: Reliability and validity assessment in stroke patients.

Illness perceptions are an important factor affecting the prognosis of stroke patients. Evaluating the illness perceptions of stroke patients is of great importance for predicting their health behaviour and rehabilitation outcomes. However, there is no specific tool for assessing illness perceptions in stroke patients in China. The objective of this study is to translate the Stroke Illness Perception Questionnaire-Revised (SIPQ-R) into Chinese and to psychometrically test the Chinese version of the scale in the population of Chinese stroke patients. This was a methodological study. We investigated 593 stroke patients in the neurology department of a hospital in China from March to September 2021. We translated the SIPQ-R and adapted it to the cultural context, after which we evaluated the reliability and validity of the Chinese version of SIPQ-R. Exploratory factor analysis identified eight common factors that accounted for 71.74% of the total variance, and the factor loadings ranged from 0.530 to 0.933. Confirmatory factor analysis confirmed the eight-factor structure (χ2/df =1.765, root mean square error of approximation =0.053, incremental fit index =0.906, comparative fit index =0.905 and Tucker-Lewis index =0.900). Internal consistency was confirmed by a Cronbach's alpha coefficient of 0.982. The test-retest reliability was 0.762. The results showed good content validity (the scale level content validity index was 0.940, and the item level content validity index values ranged from 0.860 to 0.960). There were no missing responses and floor or ceiling effects. The standard error of measurement and the smallest detectable change for the SIPQ-R were 45.49 and 126.10, respectively. The results of this study provide empirical evidence for the reliability and validity of the Chinese version of the SIPQ-R for stroke patients.
