Research on Developing an Assessment Scale for Tourism Experience Elements of Ancient Shu Road Heritage Trail

Cultural ancient roads,known in Chinese as gudao,serve as heritage trails that carry historical exchanges across various regions in China.Due to their extensive preservation,wide geographical distribution,diverse thematic variations,and considerable tourist appeal,these paths have emerged as representative heritage trails,increasingly transforming into a novel tourism product experience that is highly favored by tourists and recognized by government authorities.However,research on ancient roads for tourism in China currently lacks a systematic theoretical framework,as well as relevant policies,regulations,and standards to guide their practical development.Therefore,there is a pressing need to draw upon international best practices and conduct foundational research to develop an experience element system that aligns with the perceptions,behaviors,and consumption characteristics of Chinese tourists,thereby advancing theoretical exploration in this field.This study focuses on the representative Ancient Shu Road as a case study and employs a mixed-method approach that integrates qualitative and quantitative research.It aims to construct a tourist-centric scale for the experience elements of ancient road tourism while analyzing the interactive relationship between these experience elements and tourist needs.This study addresses a significant gap in the development of indicator systems for domestic studies of ancient road tourism experiences.Ultimately,the study establishes a comprehensive scale that encompasses three core categories—trail resources and environment,facilities and services,and modes of tourism activities—along with eight primary dimensions:core resources,surrounding cultural environment,surrounding natural environment,tourism reception facilities and services,infrastructure and support services,information facilities and information services,and outdoor and recreational activities.This scale consists of thirty-two specific items,providing a robust reference for future research endeavors.Additionally,the study proposes specific development strategies related to key mechanisms,spatial configuration,and facility construction to enhance the overall development of ancient road tourism.

Development of Self-Rated Nursing Record Frequency for Delirium Care of Nurses in Acute Care Hospitals (NRDC-Acute)

Background: Nursing records play an important role in multidisciplinary collaborations in delirium care. This study aims to develop a self-rated nursing record frequency scale for delirium care among nurses in acute care hospitals (NRDC-Acute). Methods: A draft of the scale was developed after a literature review and meeting with researchers with experience in delirium care, and a master’s or doctoral degree in nursing. We identified 25 items on a 5-point Likert scale. Subsequently, an anonymous self-administered questionnaire survey was administered to 520 nurses from 41 acute care hospitals in Japan, and the reliability and validity of the scale were examined. Results: There were 232 (44.6%) respondents and 218 (41.9%) valid responses. The mean duration of clinical experience was 15.2 years (SD = 8.8). Exploratory factor analysis extracted 4 factors and 13 items for this scale. The model fit indices were GFI = 0.991, AGFI = 0.986, and SRMR = 0.046. The Cronbach’s alpha coefficient for the entire scale was .888. The four factors were named “Record of Pharmacological Delirium Care on Pro Re Nata (PRN)”, “Record of Non-Pharmacological Delirium Care”, “Record of Pharmacological Delirium Care on Regular Medication”, and “Record of Collaboration for Delirium Care”. Conclusion: The scale was relatively reliable and valid. Nurses in acute care hospitals can use this scale to identify and address issues related to the documentation of nursing records for delirium care.

Efficacy of Children Neuropsychological and Behavioral Scale in Screening for Autism Spectrum Disorders through a Combination of Developmental Surveillance

Objective This study aimed to explore the clinical value of Children Neuropsychological and Behavioral Scale-Revision 2016(CNBS-R2016)for Autism Spectrum Disorder(ASD)screening in the presence of developmental surveillance.Methods All participants were evaluated by the CNBS-R2016 and Gesell Developmental Schedules(GDS).Spearman’s correlation coefficients and Kappa values were obtained.Taking GDS as a reference assessment,the performance of the CNBS-R2016 for detecting the developmental delays of children with ASD was analyzed with receiver operating characteristic(ROC)curves.The efficacy of the CNBS-R2016 to screen for ASD was explored by comparing Communication Warning Behavior with Autism Diagnostic Observation Schedule,Second Edition(ADOS-2).Results In total,150 children aged 12–42 months with ASD were enrolled.The developmental quotients of the CNBS-R2016 were correlated with those of the GDS(r=0.62–0.94).The CNBS-R2016 and GDS had good diagnostic agreement for developmental delays(Kappa=0.73–0.89),except for Fine Motor.There was a significant difference between the proportions of Fine Motor,delays detected by the CNBS-R2016 and GDS(86.0%vs.77.3%).With GDS as a standard,the areas under the ROC curves of the CNBS-R2016 were above 0.95 for all the domains except Fine Motor,which was 0.70.In addition,the positive rate of ASD was 100.0%and 93.5%when the cut-off points of 7 and 12 in the Communication Warning Behavior subscale were used,respectively.Conclusion The CNBS-R2016 performed well in developmental assessment and screening for children with ASD,especially by Communication Warning Behaviors subscale.Therefore,the CNBS-R2016 is worthy of clinical application in children with ASD in China.

Development and psychometric evaluation of the Ethical Behavior for Thai Nurses Scale

Background:Ethical problems in the nursing profession are mostly found in the undesirable ethical behavior(EBE)of nurses.If there is no concern about these problems,it may negatively affect the quality of nursing care,patients’safety,and trust in the nursing profession.In assessing nurses’EBE,it is important to develop an instrument that reflects the actual EBE of nurses.Objectives:To develop and evaluate the psychometric properties of the Ethical Behavior for Thai Nurses Scale(EBTNS).Methods:The construct definition,5 sub-constructs,43 items,and the hypothesized model were synthesized and generated from a comprehensive literature review and existing research instruments by using document analysis.The EBTNS was verified for content validity by 4 experts.Of the 43 items,37 items were retained for psychometric testing.The construct validity was tested by using second-order confirmatory factor analysis(CFA).The EBTNS was tested on 1500 professional nurses working at tertiary,secondary,and primary hospitals in 6 regions(the central,northern,northeast,eastern,western,and southern)of Thailand.Proportional quota sampling was applied to recruit participants.Results:The hypothesized model fitted the empirical data.All 37 first-order indicators and 5 second-order sub-constructs showed significantly standardized factor loadings and effect sizes.The standardized factor loadings of 37 first-order indicators ranged from 0.58 to 0.89,and the construct reliabilities were moderate to substantial(R2=0.34-0.79).The 5 second-order sub-constructs displayed the standardized effect sizes,ranging from 0.81 to 0.96,and accounted for 65%-96%of the total explained variance.In addition,the construct validity was supported by convergent validity and discriminant validity.It also satisfied Cronbach’s alpha coefficients of 5 sub-constructs from 0.87 to 0.94,and a full scale was 0.97.Conclusions:The psychometric properties of the EBTNS are acceptable.This instrument has the potential to be used for evaluating and monitoring to prevent ethical problems of Thai nurses.

Development and psychometric evaluation of the nurse behavior toward confirmed and suspected HIV/AIDS patients (NB-CSHAP) scale

There is a scarcity of literature discussing nurses’ behaviors toward caring for suspected or confirmed human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients. The development of a scale specific to measure nurses’ behaviors will allow health institutions to assess the disposition of their nurses in terms of HIV care. This study aims to present the rigors of developing and validating a reliable instrument to contextualize these nurses’ behaviors. This study utilized a sequential exploratory mixed method design to develop the NB-CSHAP scale. Thematic analysis was done on the qualitative data from the interviews with persons living with HIV/AIDS (PLHA) from which items were selected to be included in the scale. Exploratory factor analysis was utilized to extract the factors and Cronbach’s alpha was used to assess the reliability of the instrument. Four factors were extracted and are categorized as either caring or discriminatory behaviors. These include: (1) service-oriented, (2) openhanded, (3) perceptive, and (4) discriminatory. The scale has an internal consistency of 0.73. The scale shows acceptable psychometric properties, hence can be used to assess the nurses’ behaviors in caring for confirmed or suspected HIV clients. The scale may be used by health institutions to determine the quality of the patient care provided by their nurses to clients with confirmed or suspected HIV .

Hospital-acquired insomnia scale:A validity and reliability study

BACKGROUND Sleep breathing,one of the basic human needs,is a physiological need that affects cardiac functions,body temperature,daily vitality,muscle tone,hormone secretion,blood pressure,and many more.In the international literature,studies reported that patients have had sleep problems in the hospital since the 1990s,but no measurement tool has been developed to determine the causes of hospitalacquired insomnia in individuals.These findings suggest that sleep remains in the background compared to activities such as nutrition and breathing.Although patients generally experience hospital-acquired sleep problems,there is no measurement tool to determine hospital-acquired sleep problems.These features show the originality of the research.AIM To develop a measurement tool to determine the sleep problems experienced by patients in the hospital.METHODS A personal information form,hospital-acquired insomnia scale(HAIS),and insomnia severity index(ISI)were used to collect research data.The study population consisted of patients hospitalized in the internal and surgical clinics of a research hospital in Turkey between December 2021 and March 2022.The sample consisted of 64 patients in the pilot application stage and 223 patients in the main application stage.Exploratory factor analysis and confirmatory factor analysis(CFA)analyses were performed using the SPSS 20 package program and the analysis of moment structure(AMOS)package program.Equivalent forms method used.RESULTS The HAIS consisted of 18 items and 5 subscales.The Cronbach alpha values of the subscales ranged between 0.672 and 0.842 and the Cronbach alpha value of the overall scale was 0.783.The scale explained 58.269%of the total variance.The items that constitute the factors were examined in terms of content integrity and named as physical environmental,psychological,safety,socioeconomic,and nutritional factors.CFA analysis of the 5-factor structure was performed in the AMOS package program.The fit indices of the obtained structure were examined.It was determined that the values obtained from the fit indices were sufficient.A significant correlation was determined between the HAIS and the ISI,which was used for the equivalent form method.CONCLUSION The HAIS is a valid and reliable measurement tool for determining patients’level of hospitalacquired insomnia.It is recommended to use this measurement tool to determine the insomnia problems of patients and to adapt it in other countries.

Towards a profile-based writing scale for a local post-admission ESL writing assessment

Post-admission language tests tend to have a restricted range of proficiency levels among test-takers due to considerations made during the admission selection process.Although range restriction can present challenges for proficiency-focused assessment,it can also bring opportunities to zoom in on fine-grained performance profiles of test-takers.This study reports on the validation of a profile-based rating scale for an ESL writing placement test in a US university.The profile-based rating scale was created by employing a three-staged,hybrid scale development approach,to provide not only accurate placement decisions but also fine-grained diagnostic information regarding ESL students’writing performance profiles.The scale strikes a balance between argument development and lexico-grammar,to better account for the range of writing performances among test-takers.To gather validity evidence for the profile-based rating scale,this study employs a sequential,mixed-methods approach to examine the quality of test-taker performances across profiles and rater perceptions on the scale.Nine certified raters were recruited to conduct independent evaluations of lexicogrammar and argumentation on a sample of 150 test-taker performances.These evaluations were subjected to many-facet Rasch measurement analysis to examine the differences across writing performance profiles included in the rating scale.Next,semi-structured,follow-up interviews were conducted with the raters,to complement the quantitative findings on the usability and effectiveness of the scale.The findings provide supportive evidence for the validity of the profile-based rating scale.I argue that by focusing on performance profiles,post-admission language tests can strengthen the alignment across curriculum,instruction,and assessment in ESL writing programs.
