  • Purpose: The study was done to identify the construct validity and reliability of the life transition scale (LTS) for parents who have children with autism. Methods: Exploratory factor analysis (EFA) and confirmative factor analysis (CFA) were conducted to identify the most adequate measurement model for structural validity. Convergent validity and discriminant validity were also conducted for structural validity. Data were collected from 208 parents through self-reported questionnaires and analyzed with SPSS/WIN 15.0 and AMOS 20.0 version. Results: A four factor-structure was validated (${\chi}^2$=541.23, p<.001, GFI=.82, RMSEA=.07, IFI=.89, CFI=.89, PNFI=.73, Q (${\chi}^2/df$)=2.20) at the 3rd order of EFA and CFA, and factors were named as denying, wandering, despairing, and accepting. Both convergent and determinant validity for LTS were 100%. Cronbach's alphas for the reliability of each structure were .77-.90 and .83 for total structure. Conclusion: The four structures, 24-item instrument showed satisfactory reliability and validity. LTS has the potential to be appropriate for assessing the transition process of life for parents who have children with autism and provides basic directions for differentiated support and care at each stage.

  • Purpose - This study aims to assess six aspects of resident satisfaction (satisfaction with room, home, social interaction, meals service, staff care, and resident involvement) and to identify the most influential aspect of satisfaction upon word-of-mouth (WOM) intention in a continuing care retirement community (CCRC). Design/methodology/approach - A total of 293 paper survey questionnaires with a cover letter and postage paid envelopes were mailed to the CCRC residents. To test reliability and validity of the multidimensional resident satisfaction, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used. Then, the structural equation modeling technique (SEM) was applied to test causal relationship between resident satisfaction and WOM intention. Multiple regression was used to identify the most influential aspect of resident satisfaction on WOM intention in the CCRC. Findings - The results of EFA and CFA on the 157 responses received out of the total 293 surveys indicated that six dimensions of resident satisfaction were statistically distinct. Among the six dimensions, satisfaction with resident involvement, social interaction, and staff care significantly influenced their WOM intention. Furthermore, the most influential aspect of satisfaction upon WOM intention was resident involvement. Research implications or Originality - This study empirically tested the six dimensions of CCRC resident satisfaction, and identified resident involvement as the most influential factor upon WOM intention in a CCRC where WOM intentions plays a crucial role during the selection process of prospective residents.

  • The purpose of this study was to develop an appropriate scale for evaluating early years children's English textbooks and to confirm the validity and reliability for the scale thus developed. The scale was administered to 563 Korean early childhood English teachers. Exploratory Factor Analysis (EFA) of the 24 item scale demonstrated Cronbach' ${\alpha}$ = .94 for internal consistency of the total items. Confimatory Factor Analysis (CFA) supported a four-factor structure. Cross-Validation for the retest accepted the four-factors. Those four factors were as follows; Contents & Organization as factor 1, Illustrations & Designs as factor 2, Materials & Topics, as factor 3 and Objectives as factor 4. The author suggests that these afore mentioned factors will prove to be most useful for evaluating the children's English textbooks which are apparently published in an often quite indiscriminant manner.

  • Purpose: The purpose of this study was to develop and validate a Korean version of the Self-Care for Aspiration Pneumonia Prevention (SCAPP-K) scale in older adults at risk of dysphasia. Methods: The Hertz and Baas model of scale development and validation was used. In the development stage, items were generated via literature review and interviews with medical experts, older adults, and caregivers. Ten experts assessed the items for content validity. Subsequently, 12 older adults participated in a pilot test to determine the comprehensibility and appropriateness of the SCAPP-K scale. The validation stage involved a cross-sectional survey with 203 older adults for exploratory factor analysis (EFA) and 200 older adults for confirmatory factor analysis (CFA) and to determine convergent and discriminant validity. To test the validity and reliability of the scale, EFA using principal component analysis with varimax rotation and CFA were conducted, and convergent and discriminant validity as well as internal consistency reliability were determined. Results: As a result of EFA, three self-care factors (knowledge, resources, behaviors) with 21 items were validated. The CFA and convergent and discriminant validity indicated the applicability of the three-factor self-care scale. The reliability of the SCAPP-K scale was acceptable, with Cronbach's α=.87~.91. Conclusion: The SCAPP-K scale has acceptable validity and reliability and can contribute to clinical practice, research, and education to improve self-care for the prevention of aspiration pneumonia in older adults at risk of dysphasia.

  • Purpose: This study examined how many determinant factors (service dimensions, food quality, and price perception) affect revisit intention. This practical concept is service quality (SERVQUAL), customer satisfaction, and repeated/revisit behavioral intention based on the theory of reasoned action (TRA). Research design, data and methodology: This research applied a hybrid mixed-method comprising exploratory and explanatory sequential design by Creswell (2014). The 400 responses were collected in four townships in Myanmar. This study drilled down to exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) prior to test the hypothesized factor structure of all the variables resulted in the form of the goodness of fit. For further data analysis, structural equation modeling (SEM) was applied to test the relationships among the variables of the proposed model. Results: The results showed that perceived service quality, food quality, and price perception have direct effects on customer satisfaction and indirect effect on revisit intention. The perceived service quality has the most significant influence while the food quality has the least influence on customer satisfaction. Conclusions: The results are useful for the restaurant managers to better understand the significant strategic choice factors to improve higher quality service amongst restaurants both domestic and international under the stiff competition.

  • Background: The vulnerability of international migrant workers is on the rise, affecting the frequency of occupational accidents at workplaces worldwide. If migrant workers are managed in the same way as native workers, the consequences on safety assurance and risk management will be significant. This study aimed to develop the vulnerability factor model for migrant workers in seafood processing industries because of significant risk-laden labor of Thailand, which could be a solution to control the risk effectively. Methods: A total of 569 migrant workers were surveyed (432 Burmese and 137 Cambodian), beginning with 40 initial vulnerability factors identified in the questionnaire established from experts. The data were analyzed through descriptive analysis; exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to ascertain the model. Results: The result of content validity >0.67 and the Cronbach's alpha of 0.957 specified the high reliability of 40 factors. The EFA indicated a total variance of 65.49%. The final CFA validated the model and had an empirical fitting; chi-square = 85.34, Adjust Goodness-of-Fit Index = 0.96, and root mean square error of approximation = 0.016. The structure concluded with three dimensions and 18 factors. Dimension 1 of the structure, "multicultural safety operation," contained 12 factors; Dimension 2, "wellbeing," contained four factors; and Dimension 3, "communication technology," contained two factors. Conclusion: The vulnerability factor structure developed in this study included three dimensions and 18 factors that were significantly empirical. The knowledge enhanced safety management in the context of vulnerability factor structure for migrant workers at the workplace.

  • Today, customer satisfaction is the most important issue for Vietnamese banks. There are numerous factors that influence bank customers' satisfaction. The study investigates the factors that influence customer satisfaction with deposit services at the Vietnam Bank for Agriculture and Rural Development (Agribank) in Bac Giang province, Vietnam, and analyses the impact of each component. The authors used 5-point Likert scales to assess whether elements were related to the factors determining consumer satisfaction with Agribank's deposit service. To perform this study, exploratory factor analysis (EFA) and multiple regression were used to find factors determining customer satisfaction with Agribank services. Customers that use deposit services at Agribank in Bac Giang province, Vietnam, provided samples of 300 survey questionnaires for this study. SPSS software is used to examine the data. Customers' satisfaction with Agribank's deposit service is influenced by six factors, including reliability, responsiveness, service capabilities, empathy, tangible means, and service price, according to the study. This finding also offers some recommendations for improving service quality in local Vietnamese banks to gain a competitive advantage.

  • Purpose: The purpose of this study was to develop a scale to measure person-centered critical care nursing and verify its reliability and validity. Methods: A total of 38 preliminary items on person-centered critical care nursing were selected using content validity analysis of and expert opinion on 72 candidate items derived through literature review and qualitative interviews. We conducted a questionnaire survey with 477 nurses who worked in intensive care units. The collected data were analyzed using exploratory factor analysis (EFA) and confirmative factor analysis (CFA) with SPSS and AMOS 24.0 program. Results: EFA was performed with principal axis factor analysis and Varimax rotation. The 15 items in 4 factors that accounted for 50.8% of the total variance were identified by deleting the items that were not meet the condition that the commonality should be .30 or more and the factor loading over .40. We named the factors as compassion, individuality, respect, and comfort, respectively. The correlation coefficient between this scale and the Caring Perception Scale was r=.57 (p<.001), which determined concurrent validity. The item-total correlation values ranged from .39 to .63, and the internal consistency for the scale was Cronbach's ${\alpha}=.84$. Conclusion: The reliability and validity of the 15 item person-centered critical care nursing scale were verified. It is expected that the use of this scale would expand person-centered care in critical care nursing.
