Cross-cultural adaptation and validation of an Urdu version of the Vaccine Attitudes Examination (VAX-U) scale.

Martin and Petrie developed the Vaccine Attitudes Examination (VAX) scale with an aim to document general vaccination attitudes. Vaccine acceptance plays an important role in curbing COVID-19 infections. Thus, it was important to assess vaccination attitudes of Pakistani people towards novel COVID-19 vaccines. The VAX scale was not available in Urdu language for Pakistani population. The study aimed to carry out cross-cultural adaptation and validation of an Urdu version of the Vaccine Attitude Examination (VAX) scale in a selected population sample from Pakistan. A cross sectional study was conducted in September 2021 in an outpatient department of a healthcare facility in Karachi, Pakistan. Adult visitors, eligible for COVID-19 vaccine and spoke Urdu as first language were invited. Convenient sampling was used, and sample size was based on an item response ratio of 1:20. An Urdu version of the VAX scale was developed. The reliability was assessed using Cronbach's alpha (α) and intraclass correlation coefficient (ICC). The model fitness was evaluated using confirmatory factor analysis (CFA) and fit indices namely goodness of fit index (GFI), adjusted goodness of fit index (AGFI), Tucker Lewis index (TLI), comparative fit index (CFI), and root mean square error of approximation (RMSEA). A structural equation model (SEM) was also developed. IBM SPSS and AMOS were used to analyse the data. The study had ethical clearance. A total of 211 responses were analysed. The reliability (Cronbach's α) was 0.821. The ICC was 0.831 (95% CI: 0.795-0.863). CFA using a 4-factor model revealed the following values for fit indices; GFI = 0.944, AGFI = 0.909, TLI = 0.953, CFI = 0.966, and RMSEA = 0.051. All values reported were in the acceptable range. The VAX Urdu version is a reliable and valid instrument for use in an Urdu speaking population and will enable clinicians to assess the public's attitude towards general vaccination including COVID-19 vaccination. Clinicians can use the VAX-U to document a person's vaccine hesitancy and tailor their counselling to address the issues in vaccine uptake.

Development of cyber wellness indicators among Thai older persons: Mixed method research

ABSTRACT This mixed methods Ph.D. study aims to evaluate the structure of a new five component Cyber Wellness model from research with 320 participants from a multi-stage random sampling method. This model includes five components found from critical literature review: 1. Cyber Use, 2. Cyber Citizenship, 3. Cyber Ethical Relationship, 4. Cyber Safety and 5. Cyber Rights. Participants responded to a 5-point Likert scale with X questions. In our analysis, we found an overall Cronbach’s alpha was .938, with individual component alphas ranging from .733 to .889. Statistical analyses included; mean, percentage, standard deviation, and confirmatory factor analysis. We found that each model component demonstrated significance at the .01 level, with factor loadings ranging from .71 to .96, with the highest factor loading for being Cyber Ethical Relationship. This means that improved cyber ethical relationships among older individuals could greatly enhance their overall wellness. Our confirmatory factor analysis results showed Chi-Square (χ2) = 64.00, df = 50, p = .088, goodness of fit index (GFI) = .97, adjusted goodness of fit index (AGFI) = .95, root mean square error of approximation (RMSEA) = .030. These results indicate that the chi-square value significantly differs from zero at the .05 level, supporting our main hypothesis that the measurement model aligns with empirical data and that the Cyber Wellness model developed in this study can serve as a foundational concept for designing learning programs that enhance Cyber Wellness among Thai older people using the identified indicators to create micro-learning modules suitable for their needs.

A causal model of eating behaviors among Thai pregnant women working in industrial factories

Abstract Objective This study aimed to examine the causal model of eating behaviors among pregnant women working in industrial factories. Methods This cross-sectional study was conducted on 210 participants, attending 4 healthcare centers, at a tertiary care hospital in Chonburi province, Thailand. Data were collected using 7 questionnaires: demographic form, eating behavior questionnaire, perceived benefits of the healthy eating questionnaire, perceived barriers to the healthy eating questionnaire, perceived self-efficacy questionnaire, social support questionnaire, and accessibility to healthy foods questionnaire. Descriptive statistics and path analysis were used for data analysis. Results The participants had relatively high mean scores for eating behaviors. The final model fitted well with the data χ2 = 12.86, df = 10, P = 0.23; χ2/df = 1.29; comparative fit index (CFI) = 0.98; goodness-of-fit index (GFI) = 0.98; adjusted goodness-of-fit index (AGFI) = 0.95; root mean square error of approximation (RMSEA) = 0.04. Four factors—perceived benefits (β = 0.13, P < 0.05), perceived self-efficacy in healthy eating (β = 0.22, P < 0.001), pregnancy planning (β = 0.28, P < 0.001), and accessibility to healthy foods in the factory (β = 0.12, P < 0.05)—positively affected eating behavior, while only perceived barriers to healthy eating had a negative effect on eating behavior (β = −0.24, P < 0.001). All the above factors explained 27.2% of the variance in eating behaviors. Conclusions Nurses or healthcare providers can apply these findings to create an eating behavior modification program, focusing on pregnancy planning, behavior-specific variables, and interpersonal and situational influence, to promote the nutritional status of pregnant women working in industrial factories.

It serves as an assessment instrument usable by healthcare professionals to evaluate adult individuals' beliefs regarding complementary and alternative medicine (CAM) methods.

Development and validation of the perceived symptom manageability scale among people living with the human immunodeficiency virus

Background“Perceived Symptom Manageability (PSM)” is essential in symptom management among people living with HIV. As a standardized assessment instrument was lacking, we developed a PSM scale for people living with human immunodeficiency virus (PSM-HIV).MethodsData analysis was performed using the sample from HIV-designated medical institutions (N = 540). Psychometric testing, namely reliability and validity, is assessed by unidimensionality, internal consistency, exploratory and confirmatory factor analysis, and structural equation modeling.ResultsThe final version of the PSM- HIV scale contained 15 items. This scale was submitted to a principal components analysis with varimax rotation, and three factors were obtained, explained by a total variance of 63.10%. The three factors were named Cognitive-Behavioral, Affective Interaction, and Self-Attitude. The results show that the scale had high reliability, Cronbach’s α of the scale ranged from 0.71 to 0.92, and the Intraclass Correlation Coefficient was 0.88. The structural equation model supports a factor model with the acceptable fit (χ2/df (CMIN/DF) = 2.50, Root Mean square Residual (RMR) = 0.03, Goodness-of-Fit Index (GFI) = 0.93, Adjusted Goodness of Fit Index (AGFI) = 0.90, Normed Fit Index (NFI) = 0.93, Incremental Fit Index (IFI) = 0.96, Comparative Fit Index (CFI) = 0.96). The average variance extracted was 0.38 ∼ 0.59, and the composite reliability was 0.70 ∼ 0.91, indicating that the convergent validity of the scale is acceptable. Subjects with different stages of the disease reached significance(χ2 = 9.02; df = 2, P<0.05), meaning moderate Known-Groups Comparison Validation.ConclusionsThe PSM-HIV scale is a valid instrument that measures overall attitude and belief about controlling or coping with HIV-relevant symptoms.

Validity arguments for creating a short motivation scale through adaptation of the Japanese motivated strategies for learning questionnaire

Background The coronavirus disease pandemic has substantially altered the mode of medical education, transitioning it from in-person to online. Online learning requires a strong motivational foundation to support self-directed studying. In our previous study, an adapted 31-item Japanese motivation measurement scale using the motivational section from the Japanese version of the Motivated Strategies for Learning Questionnaire (J-MSLQ) was developed. The present study aimed to collect evidence on the validity of the motivation section of the J-MSLQ and clarify whether further revision was necessary. Methods The motivation section of the J-MSLQ comprises a seven-point Likert scale survey containing 31 items. Of 127 fourth-year Japanese medical students invited to participate, 112 responded. Confirmatory factor analysis with structural equation modeling (SEM) was performed using R and R studio for all data analysis. Results The initial SEM model that incorporated all 31 items exhibited inadequate goodness of fit metrics: χ2 = 823.674 (p &lt; 0.001), the comparative fit index (CFI) = 0.786, the root mean square error of approximation (RMSEA) = 0.093, the standardized root mean square residual (SRMR) = 0.112, the goodness of fit index (GFI) = 0.664, and the adjusted goodness of fit index (AGFI) = 0.602. We optimized the scale by eliminating 12 items with a Z test statistic &lt; 10. Improvements in the goodness of fit metrics of the optimized SEM model were observed, demonstrating moderate model fit: χ2 = 205.602 (p &lt; 0.001), CFI = 0.929, RMSEA = 0.080, SRMR = 0.063, GFI = 0.837, AGFI = 0.768. Conclusions A compact 18-item version of the motivation scale was developed and validated, which alleviated the respondent burden and enabled the researchers to collect data in a shorter time.

Effects of sleep quality on pain, cognitive factors, central sensitization, and quality of life in patients with chronic low back pain.

Sleep quality in patients with chronic low back pain (CLBP) may affect quality of life (QoL), possibly due to worsening pain, central sensitization (CS), and cognitive factors. However, causal relationship among the factors has not been confirmed yet. The purpose of this study was to test the hypothesis that sleep quality in patients with CLBP is attributable to pain, cognitive factors, and CS, and influences QoL, by structural covariance analysis. This is a cross-sectional study. Participants were recruited from six health care facilities and 101 patients with CLBP were included. Structural covariance analysis assessed the fit of data to the model using goodness of fit index (GFI), adjusted goodness of fit index (AGFI), comparative fit index (CFI), and mean squared approximation error (RMSEA). The structural covariance analysis showed that the goodness-of-fit indices were high (GFI = 0.993, AGFI = 0.964, CFI = 1.00, RMSEA < 0.01). Sleep quality was not directly influenced by QoL but rather by CS and cognitive factors. This study suggests that sleep quality in patients with CLBP is indirectly mediated through multiple pathways, including cognitive factors and CS, which may influence QoL.

This study aimed to present a model for empowering hospitalized patients. This study is a quantitative-qualitative cross-sectional study conducted using stratified sampling with appropriate allocation in public hospitals affiliated with Shahid Sadoughi University of Medical Sciences, Yazd. The study involved 230 participants, including hospital directors, managers, matrons, supervisors, clinical and paraclinical unit heads, staff units, nurses, and physicians. Data were collected using demographic information tools and a researcher-made questionnaire designed to create a model for empowering hospitalized patients. The model's capability was determined by fitting the data using confirmatory factor analysis. Data were analyzed using SPSS version 16 and Amos version 24 software. The questionnaire designed for the patient empowerment model in hospitals comprised 8 domains and 61 items or components. In this study, the chi-square ratio to degrees of freedom was significant (p &lt; 0.0001), indicating a good fit for the model. The Goodness of Fit Index (GFI) was estimated at 0.93, showing that the model fit was appropriate. The values of GFI and the Adjusted Goodness of Fit Index (AGFI) for the hospitalized patient empowerment model were above 0.8. Organizations and educational healthcare centers can use this model to empower patients. The necessary groundwork for enhancing patient empowerment should be provided by medical universities and affiliated hospitals.

ObjectiveTo translate the Academic Goals Orientation Questionnaire (AGOQ) into Chinese and to determine the validity and reliability of the (AGOQ) in Chinese nursing students based on SEM and IRT multidimensional models.MethodsThe participants were 654 nursing students with an age range of 17–26 years (mean age 21.61 ± 1.73 years). The psychometric properties of AGOQ were investigated based on a dual analytical perspective of structural equation modeling (SEM) and item response theory (IRT).ResultsThe Cronbach’s α value of the questionnaire is 0.895. A four-factor model was obtained by exploratory factor analysis, which explained the variance of 71.892%. With confirmatory factor analysis, a new four-factors model was built and showed an acceptable goodness-of-fit, chi-square/degree of freedom (CMIN/DF) = 4.008, goodness of fit index (GFI) = 0.932, adjusted goodness of fit index (AGFI) = 0.905, comparative fit index (CFI) = 0.952, incremental fit index (IFI) = 0.952, Tucker Lewis index (TLI) = 0.941. In the analysis part of IRT, according to the comparison between Akek’s information criterion (AIC) and Bayesian information criterion (BIC), we choose the Graded Response Model (GRM) for analysis. The results show that the difficulty value is monotonically increasing, and the discrimination of all items is greater than 0.19, which shows that 16 items can be retained.ConclusionsThis study tested the psychometric characteristics of AGOQ of nursing students in China. The results confirmed that the Chinese version of AGOQ has good psychometric characteristics and can be used to measure the academic goal orientation of nursing students in China.

Translation and validation of an Urdu version of the Vaccine Attitudes Examination (VAX) scale

Abstract Introduction Despite being one of the most effective methods of preventing the spread of communicable diseases1, vaccination has been subjected to criticism. Several scales have been formulated that were used to document attitudes towards vaccination. However, they either focus on parental attitudes towards children’s vaccinations or are targeted towards an individual’s attitude towards a specific vaccine. A scale that could document an individual’s attitude about vaccinations in general was developed by Martin and Petrie2. Aim The study aimed to translate and validate an Urdu version of the Vaccine Attitude Examination (VAX) scale in a selected Pakistani sample. Methods A cross sectional study was conducted for a month (Sept. 2021) in an outpatient department of a healthcare facility in Karachi, Pakistan. All adult men and women, as well as their caregivers (≥ 18 years), who visited the clinic, spoke Urdu as their first language, and were eligible for COVID-19 vaccine were invited. Convenience sampling method was selected, and sample size calculation was based on an item response ratio of 1:20. An Urdu version of the VAX scale was developed. Data were analysed using IBM SPSS version 23. The reliability was assessed using Cronbach’s alpha (α) and intraclass correlation coefficient (ICC) was calculated. The model fitness was evaluated through IBM AMOS version 25. It done carried out using confirmatory factor analysis (CFA) and reporting of fit indices, namely goodness of fit index (GFI), adjusted goodness of fit index (AGFI), Tucker Lewis index (TLI), comparative fit index (CFI), and root mean square error of approximation (RMSEA). The scale was considered as reliable if Cronbach’s (α) was &amp;gt;0.7. Model fitness was considered acceptable if most fit indices were in acceptable ranges3, i.e., GFI, TLI, CFI &amp;gt; 0.9 and RMSEA &amp;lt; 0.6, as well as p value &amp;lt; 0.05. This study was granted ethical clearance by the Institutional Review Board of Tabba Heart Institute, Karachi, Pakistan (Reference# THI/IRB/FQ/22-09-21/017). Results A total of 211 responses were analysed. The reliability of the scale, i.e., Cronbach’s alpha value was 0.821, and remained the same, i.e., &amp;gt; 0.8 during item deletion. CFA using a 4-factor model revealed the following values for fit indices; GFI = 0.944, TLI = 0.953, CFI = 0.966, and RMSEA = 0.051 (p value = 0.008). Discussion/Conclusion Although a very small scale study, the findings suggest that the Urdu version of VAX scale is reliable and a valid instrument for use in an Urdu speaking population. The scale showed good internal consistency and acceptable model fitness. The use of convenience sampling and being conducted at a single site may affect the generalisability of the results. However, this was the first time the VAX Urdu version was made available for an Urdu speaking population. It is hoped that the attitudes toward vaccines that are measured by the Urdu VAX will provide valuable information as public health officials and others work to improve vaccine uptake. Availability of the Urdu version will enable clinicians to assess the Urdu speaking persons’ attitude towards general vaccination including COVID-19 vaccination.

Development and validation of teachers’ psychological empowerment scale in Ethiopian context

The low motivations of teachers in Ethiopia reflect the psychological deempowerment of teachers. Thus, developing a scale is required to know exactly the empowerment level of teachers. Therefore, this study aimed at developing and validating a psychological empowerment scale in the Ethiopian context. The data were gathered from two different groups of 720 teachers (300+420) from 83 schools using a questionnaire. The exploratory factor analysis (EFA) results discovered four dimensions with a total variance of 69.685%. To know the fitness of the instrument in this study, the researcher carried out confirmatory factor analysis (CFA) with the LISREL 8.7 program with 420 participants. RMSEA (RootMean Square Error of Approximation) = .065 level, GFI (Goodness of Fit Index) = .93, adjusted goodness of fit index (AGFI) = .90, incremental fit index (IFI) = .98, relative fit index (RFI) = .96, non-normed fit index (NNFI) = .98 and comparative fit index (CFI) = .98. These values depict the good fitness of the model. Regading reliability, Cronbach’s alpha for goal internalization. Meaning, influence, and competence dimensions were 0.87, 0.842, 0.777, and 0.789, respectively. Total Cronbach’s alpha was .904. For this scale, the Average Variance Extracted and Combined Reliability are more than .7. Thus, the findings revealed that the psychological empowerment Scale, consisting of four dimensions and 15 items, was a valid and reliable instrument in Ethiopian school settings.

Analyzing the Critical Factors in Aircraft Maintenance That Affect Low-Cost Airlines in Thailand

This study offers an in-depth examination of salient factors pivotal to aircraft maintenance management. Through a rigorous statistical methodology, critical variables—namely, flexibility, cost control, and service quality and delivery—were discerned as cardinal elements in efficacious management within this domain.The constructed model demonstrated formidable statistical validity, solidifying its utility as a potent instrument for both evaluation and strategic guidance within the aviation milieu. The relative weights ascribed to each variable shed light on their hierarchical significance, furnishing actionable insights for organizations in their quest for operational enhancement. For the rigorous scrutiny and validation of such statistical models, a repertoire of goodness-of-fit indices is paramount. To this end, the current study leveraged a myriad of indices including the Comparative Fit Index (CFI), Goodness of Fit Index (GFI), Adjusted Goodness of Fit Index (AGFI), Root Mean Square Error of Approximation (RMSEA), Normed Fit Index (NFI), Incremental Fit Index (IFI), and Root Mean Square Residual (RMR).Nonetheless, it is prudent to recognize the potential variances in the weightages and salience of these variables across diverse organizational landscapes and contexts. This underscores the necessity for bespoke adaptations to cater to unique organizational exigencies. Cumulatively, this investigation augments the existing corpus of knowledge on aircraft maintenance management, proffering a robust quantitative scaffold for aviation entities to streamline operations, institute cost efficiencies, and uphold service excellence.

Translation and validation of the Sindhi version of the general medication adherence scale in patients with chronic diseases.

Background: There is no medication adherence scale available in Sindhi language currently. Hence, the Sindhi speaking population will either use a translator or provide their medical history in another language for documentation of medical conditions. This poses a challenge in monitoring and evaluating adherence to medications within this linguistic community. Aim: The aim of this study was to translate and validate the Sindhi version of the General Medication Adherence Scale (GMAS-S) in patients with chronic diseases. Methods: This was a cross-sectional study of 4 months duration and was conducted in out-patient department of a university affiliated hospital in Karachi, Pakistan. All adults with chronic diseases, who were on long-term medications, and able to read and understand Sindhi language were invited. Convenience sampling was employed and a questionnaire consisting of demographic questions and the Sindhi version of GMAS was used. The translation of the scale was carried out. Confirmatory factor analysis (CFA) was conducted, and a structural equation model (SEM) was developed. Fit indices, namely, goodness of fit index (GFI), adjusted goodness of fit index (AGFI), Tucker Lewis index (TLI), comparative fit index (CFI), and root mean square error of approximation (RMSEA) were reported. Reliability was assessed using Cronbach's alpha (α), intraclass correlation coefficient (ICC), corrected item-to-total correlation (ITC) and item deletion. Data were analysed through IBM SPSS version 23 and IBM AMOS version 25. The study obtained ethical clearance. Results: A total of 150 responses were analysed. The reliability of the Sindhi version of GMAS was (α) = 0.696. The intraclass correlation coefficient (ICC) was reported at 0.696 (95% CI: 0.618-0.763). The values for the fit indices were as follows: χ2/df = 1.84, GFI = 0.918, TLI = 0.920, CFI = 0.942, AGFI = 0.864, and RMSEA = 0.075. All values except AGFI were in the acceptable ranges and indicated good fitness. Most participants (80.7%) appeared non-adherent to their medications. Conclusion: The results of the study demonstrate that the Sindhi version of the GMAS is a valid and reliable scale to measure adherence in Sindhi speaking persons with chronic diseases.

The translation process of the culturally sensitive active aging scale for community-dwelling older adults in Pakistan

BackgroundThe assessment of active aging levels in Pakistani older adults is crucial yet; research tools are scarce in the local language. Therefore, this study aims to translate and validate the English version of an Active Aging Scale into a cross-culturally sensitive Urdu version to assess active aging levels in Pakistani older adults.MethodsTo translate and validate the scale, we used the ISPOR (International Society for Pharmacy Economic and Outcome Research) standards. Reliability, concurrent validity, construct validity, convergent validity, and discriminatory validity were checked on a total sample of 160 community-dwelling older adults. After two weeks, the test–retest reliability was examined. AMOS version 23 and SPSS version 23 were used to analyze the data.Results The average content validity index for clarity was 0.91 and relevancy was 0.80. The total variance in the pilot study of all items secured > 0.3 variances except for two items scored < 0.30 that were omitted before the validity and reliability test. The remaining items explained 65.46% of the overall variation and had factor loadings ranging from 0.46 to 0.90 in the principal factor analysis (PFA). The confirmatory factor analysis of the Active Aging Scale revealed that the model fit was good with a Chi-square value (418.18 (DF = 2.2) which is less than 3.00. This is further evidenced by the root mean square error of approximation (RMSEA) of 0.042, goodness of fit index (GFI) of 0.92, adjusted goodness of fit index (AGFI) of 0.94, and comparative fit index (CFI) values of 0.92 and 0.96 (unstandardized and standardized, respectively). The scale’s Cronbach’s alpha coefficient was 0.88, indicating dependability and its test–retest reliability with the significance of (P. < 0.05).ConclusionThe Urdu version of the Active Aging Scale was successfully translated and validated in a culturally sensitive manner, and can be used to evaluate the effectiveness of various active aging interventions for older adults in Pakistan.

Structural equation modelling of work related musculoskeletal disorders among dumper operators

The aim of this study is to investigate the impact of personal factors, habitual factors, and work-related factors on work-related musculoskeletal disorders (WRMSDs) among dumper operators. In total, 248 dumper operators working in an iron ore mine were considered for this study. A questionnaire was developed and administered to collect dumper operators' personal, habitual, and work-related data. The reliability of the questionnaire was cross-checked by Cronbach alpha and the test–retest method. The values of Cronbach alpha for all latent variables were above 0.7, and the correlation coefficient of the questionnaire items at Time 1 and Time 2 was above 0.82. After verifying the validity (i.e., convergent and divergent) of the questionnaire data, the relationship between the factors under consideration was examined by structural equation modeling (SEM). The SEM demonstrated a moderate fit, with frac{{upchi }^{2}}{df} value of 1.386, comparative fit index (CFI) of 0.86, goodness-of-fit index (GFI) of 0.72, adjusted goodness-of-fit index (AGFI) of 0.69, Tucker-Lewis Index (TLI) of 0.83, normed fit index (NFI) of 0.71 and root mean square error of approximation (RMSEA) of 0.051. The SEM analysis revealed a positive relationship between WRMSDs and personal factors (with path coefficient = 0.313 and p < 0.05) as well as work-related factors (with path coefficient = 0.296 and p < 0.05). However, the relationship between WRMSDs and habitual factors was not statistically significant (with path coefficient = 0.142 and p > 0.05). Overall, this study provides valuable insights into the factors that influence the prevalence of WRMSDs among dumper operators. The findings highlight the significance of personal and work-related factors by which one can make a positive decision to prevent and reduce the incidence of WRMSDs among dumper operators.

Psychometric properties of the Coronavirus Anxiety Scale based on Classical Test Theory (CTT) and Item Response Theory (IRT) models among Chinese front-line healthcare workers

BackgroundSince March 2022, the COVID-19 epidemic has rebounded widely and frequently in China. Healthcare workers have faced grand challenges such as soaring COVID-19 patients, being busy with the nucleic acid screening of all the populations in the epidemic areas every day, and testing positive for COVID-19, all of which contributed to anxiety easily according to the Conservation of Resources theory. However, anxiety among healthcare workers is not only associated with personal health but also adversely affects the quality of health services. Therefore, it is crucial to search for suitable tools to monitor the anxiety related to COVID-19 among healthcare workers. The current study aimed to test the Coronavirus Anxiety Scale (CAS) in Chinese healthcare workers.MethodsThe current study employed a cross-sectional design. The CAS was translated into Chinese. Then, according to Classical Test Theory (CTT) and Item Response Theory (IRT) models, the psychometric properties of the Chinese version were measured among 811 healthcare workers.ResultsThe split‐half reliability was 0.855. The Cronbach’s α coefficient was 0.895. The retest coefficient was 0.901 with 10 days as the retest interval. The content validity index was 0.920. In exploratory factor analysis, one common factor was extracted and explained 72.559% of the total variance. All item load values on the common factor ranged from 0.790 to 0.885, and the communality of each item ranged from 0.625 to 0.784. With confirmatory factor analysis, the single factor model showed an excellent goodness-of-fit, chi-square/degree of freedom (χ2/df) = 3.339, goodness of fit index (GFI) = 0.992, adjusted goodness of fit index (AGFI) = 0.975, root-mean-square error of approximation (RMSEA) = 0.054, root mean square residual (RMR) = 0.005, incremental fit index (IFI) = 0.967, Tucker-Lewis index (TLI) = 0.932, and comparative fit index (CFI) = 0.966. The multiple-group confirmatory factor analysis revealed the invariance measuring anxiety of COVID-19 was in similar ways across ages, hospital degrees, and professional titles. With convergent validity, the CAS was positively correlated with post-traumatic stress disorder (r = 0.619, P < 0.001), fear of COVID (r = 0.550, P < 0.001), and depression (r = 0.367, P < 0.001). According to IRT models, the results showed that all item discrimination parameters were higher than 1.70 and difficulty parameters ranged from 1.13 to 2.83.ConclusionThe Chinese version of CAS has good psychometric properties in healthcare workers after China adjusted the COVID-19 management measures during the COVID-19 Omicron epidemic, and can be used for assessing the anxiety associated with COVID-19 in Chinese healthcare workers.

Compilation and evaluation of gastrointestinal endoscopy satisfaction scale.

Gastrointestinal endoscopy plays an important role in the diagnosis and treatment of gastrointestinal diseases. The satisfaction degree of gastrointestinal endoscopy can directly affect the patient's compliance and further impact the treating effect. At present, there is no scale to evaluate the satisfaction degree of gastrointestinal endoscopy in China. This study aims to develop a satisfaction scale of gastrointestinal endoscopy suitable for national conditions and to evaluate its reliability and validity, which provides a tool for clinic to evaluate patients' satisfaction with gastrointestinal endoscopy. The original gastrointestinal endoscopy satisfaction scale was compiled by literature review, consulting senior endoscopists and experts. Through the first round of survey about 120 patients, the original scale was analyzed and modified according to the results to get the gastrointestinal endoscopy satisfaction scale (formal scale). The formal scale was used to conduct the second round of survey about 200 patients. The reliability and validity of the scale were analyzed and evaluated according to the survey results. The reliability of the original scale was good but the validity was poor. The formal scale had 2 dimensions and 10 items, the Cronbach's alpha and split-half reliability were 0.889 and 0.823. The structure validity index χ2/df was 2.513, root mean square error of approximation (RMSEA) was 0.094, goodness of fit index (GFI) was 0.914, adjusted goodness of fit index (AGFI) was 0.861, comparative fit index (CFI) was 0.946, normed fit index (NFI) was 0.915. The aggregate validity was general, the discriminative validity was good, and the direct score of patients was strongly correlated with the total score of the scale. The gastrointestinal endoscopy satisfaction scale has good reliability and validity, which can be used as a tool to evaluate patients' satisfaction with gastrointestinal endoscopy in China.

A Confirmation Factor Analysis of the Potential Level Scale for Halal Tourist Sites in Lower Songkhla Lake

This research aims to examine the coherence between the potential levels of halal tourist attractions in the lower Songkhla lagoon area for Muslim tourists with empirical data. The sample consisted of 400 Muslim tourists. This research used questionnaire to collect the data which had a confidence value of Cronbach's Coefficient Alpha with a confidence value of 0.960. The researchers analyzed the structural validity of the potential levels about halal tourist attractions around the lower Songkhla lagoon for Muslim tourists by analyzing the second corroborative component using a statistical computer program. The second corroborative component analysis revealed that the potential levels of Halal Tourist Sites in the Lower Songkhla lagoon consisted of 6 components of equal importance with component weights of 0.78, 0.84, 0.83, 0.93, 0.90, and 0.87. The results of checking the consistency of the empirical component model found that the chi-square statistic is 391.24 at 259 degrees of freedom, the probability is 0.00, the relative chi-square statistic is 1.51, the Goodness of Fit Index (GFI) is 0.93 and the Adjusted Goodness of Fit Index (AGFI) is 0.90, the Comparative Fit Index (CFI) is 0.99, the Root Mean Square Residual (RMR) is 0.02 and the Root Mean Square Error of Approximation: RMSEA) is 0.04, which indicates that the potential levels of halal tourist attractions in the lower Songkhla lagoon area for Muslim tourists consistent with the empirical data and it consists of 6 components: Accessibility, Environment, Tourism Management, Facilities, Value, and Response.

Development and Validation of the Knowledge, Attitude, and Practice Questionnaire for Community Pharmacy Personnel in Tuberculosis Case Detection, Drug Monitoring, and Education: A Study from Indonesia.

Validated and standardized structured questionnaires based on psychometric analysis are extremely limited, particularly for assessing community pharmacy personnel's knowledge, attitude, and practice (KAP) in tuberculosis (TB) case detection, drug monitoring, and education. We, therefore, developed and validated a questionnaire to assess the KAP of community pharmacy personnel in TB case detection, drug monitoring, and community education. This study was conducted in two phases. First, we developed the questionnaire, which included framework development, item generation, individual item content validity index (I-CVI), item screening, and pre-testing. Second, we validated the questionnaire with 400 participants using various analyses, including participant analysis, confirmatory factor analysis (CFA), adjusted goodness-of-fit index (AGFI), comparative fit index (CFI), non-normed fit index (NNFI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR). We determined the reliability test using Cronbach's alpha and test-retest reliability using Pearson's correlation. In the development phase, we defined 63 items that comprised 18 sociodemographic, 18 knowledge, 18 attitude, and 9 practice items. Across the 63 items, the I-CVI scores of sociodemographic and KAP items were one each. The CFA model parameter values were X2/df= 2.28; AGFI = 0.95; CFI = 0.99; NNFI = 0.98; RMSEA = 0.06; and SRMR = 0.03 (p < 0.05 for all). Cronbach's alpha coefficients of KAP items were 0.75, 0.91, and 0.95, respectively. The test-retest reliability coefficients of KAP were 0.84, 0.55, and 0.91, respectively (p < 0.01). This study indicates that the developed questionnaire is a valid and reliable instrument for assessing the KAP of community pharmacy personnel for TB case detection, drug monitoring, and community education in Indonesia. Community pharmacy personnel can support TB notification and treatment by assessing their prospective roles in surveys using this questionnaire, enabling TB eradication in 2030.
