The Internet of Things and will change the nature of activities and services in the market. In fact, for emerging markets, the untapped and growing investment opportunities and the economic leap against the Internet of Things are so enticing and facilitating that it is impossible to resist. and neglecting it will cause irreparable damage to agility. Therefore, the success of the Internet of Things for emerging markets depends on the preconditions of integration of activities carried out by decision-making organizations, facilitation of regulations, and communication and interaction between relevant sectors, which should be considered a priority through cross-sectoral research.

Validation and efficacy of the Varix Trainer model as a Training device for esophagogastroduodenoscopy.

Background and study aims The Varix Trainer model 1 (VTM1) was created for trainees to safely practice basic endoscope manipulation skills. The VTM1 was tested to see if it could distinguish levels of endoscope manipulation skills (construct validity) and whether training with it could improve these skills faster (content validity). Patients and methods We enrolled 23 novice endoscopists, 18 second-year trainees, and 13 expert endoscopists. They were asked to point with the endoscope tip to 20 numbers in the model as quickly as possible using torque, single-hand small/large wheel manipulation (SHSW), and retroflexion techniques. Their mean times (t20) were compared to determine if the model could distinguish different levels of expertise. Subsequently, 14 novices trained for eight short sessions, and the pre-training and post-training t20 were compared. Nine novice endoscopists received no training and were retested after 4 to 6 weeks (controls). Results Experts had faster t20 than second-year trainees, who were faster than novices, for all three techniques ( P < 0.001). After eight sessions, the mean t20 for novices improved from 112 to 66 seconds for torque, 144 to 72 seconds for SHSW, and 108 to 63 seconds for retroflexion, (all P < 0.001). Their t20 were equivalent to second-year trainees. Improvement in t20 was also seen with the control group, but total reduction was less than for the training group. Conclusions The VTM1 distinguished varying levels of expertise for all techniques, suggesting that it is a valid tool for assessing endoscope manipulation skill. A short curriculum improved novices' manipulation skills faster than traditional practice.

Cross-cultural adaptation of the empowerment scale of pregnant women in China context: An integrative method of translation and linguistic validation.

To translate the Empowerment Scale for Pregnant Women (ESPW) into Chinese and to assess its linguistic validity. The integrative method of the translation process, the Delphi technique, and cognitive interviews were used to implement cross-cultural adaptation and enhance comprehensibility and linguistic validation. This study recruited 14 experts in the expert review and cognitively reviewed 15 pregnant women. The two-round Delphi method created agreement on cultural applicability. The results of content validity achieved good levels: The item-level content validity index (CVI) ranged from 0.78 to 1.00, and the scale-level content validity index, calculated using two different formulas, were 0.97 and 0.81, respectively. Kappa values ranged from 0.74 to 1.00. Pregnant women could understand most of the items and response options in the cognitive interview. The revisions to the wording were made based on suggestions from experts and pregnant women. The prefinal simplified Chinese ESPW was semantically and conceptually equivalent to the English version, which was well prepared for further psychometric tests in the next stage of cross-cultural adaptation. This comprehensive method successfully developed a Chinese tool to measure the empowerment of pregnant women, indicating the international applicability of this tool and the methodological scientific nature. The simplified Chinese ESPW has the potential to support the identification of empowerment levels of pregnant women and the evaluation of the effectiveness of health education and promotion programmes.

The society human immunodeficiency virus health literacy scale: the development and psychometric assessment

Society human immunodeficiency virus (HIV) related health literacy is an essential behavioural skill that contributes to understanding the disease and responding to people living with HIV. Measuring HIV health literacy in the community requires reliable tools to produce an objective health literacy index. This study aimed to design and examined the society HIV health literacy scale's (SHIVAL) psychometric properties. A cross sectional study was conducted on 381 people without HIV. Sample recruitment used convenience sampling. Instrument development and psychometric analysis include item pool construction and content validity examination, consistency reliability test, and exploratory and confirmatory factor analysis. A standardized four factor model fits the HIV health literacy measure well. This scale has 15 items with good Cronbach's Alpha reliability index and content validity index. The final SHIVAL Scale has been determined reliable and appropriate for measuring health literacy related to HIV. Nurses or healthcare professionals can use this scale to predict an individual's HIV health literacy, thereby influencing the social intervention of HIV disease and enabling effective community health literacy strategies.

The Paediatric Palliative Screening Scale is a reliable tool that can assist in timely evaluating children who qualify for Paediatric Palliative Care. The tool can be used in Italian healthcare settings with its cultural adaptation. • Despite the lack of early diagnosis techniques, there is a significant increase in the number of children entitled to Paediatric Palliative Care. • A specific screening tool called the Paediatric Palliative Screening Scale determines a child's suitability for paediatric palliative treatment. • The Paediatric Palliative Screening Scale is necessary to assess the psychosocial needs of patients eligible for Paediatric Palliative Care. The Italian scale has good content and face validity ensuring equivalence between the original and target populations.

School Corporate Social Responsibility Scale: A Validity and Reliability Study

The aim of this study is to develop a valid and reliable instrument to measure the performance of schools in relation to corporate social responsibility based on teachers’ perceptions. To this end, content and construct validity and reliability studies were conducted with the participation of 521 teachers from four different study groups. As part of the related studies, a comprehensive literature review on the phenomenon was conducted and the theoretical structure was revealed through open-ended questions to the first study group of thirty teachers. An item pool was then created in accordance with the existing scope and the type of scale was determined. Eight experts were consulted for the item pool and the item pool was finalised and a draft scale form consisting of thirty-one items was produced. The draft scale, with the addition of the administration instructions, was administered to the second study group, a group of forty teachers, and thus the pre- application was realised. The scale that emerged after the pre-test was applied to a total of 451 teachers from two different study groups for exploratory and confirmatory factor analyses, and validity and reliability analyses were conducted on the data obtained from the study groups. These analyses showed that the total variance explained by the nine-item, one-factor structure that emerged from EFA was 81.8%, and the construct validity of the scale was supported by confirming the emerging structure with CFA. Reliability analyses revealed that Cronbach’s α and McDonald’s ω values were 0.975 and 0.976 respectively, and these values, which were quite high, proved that the scale was a reliable scale. As a result, a valid and reliable scale capable of measuring teachers’ perceptions of the CSR performance of the schools where they work has been introduced to the literature.

A Study of Psychometric Properties of Difficulty in Emotion Regulation Scale – Thai Version among Thai Population

Objective: Individuals with psychiatric disorders are found to struggle with emotion regulation, which is considered a transdiagnostic factor. However, due to a limitation in the assessment of emotion regulation in Thailand, this study aimed to translate the Difficulty in Emotion Regulation Scale (DERS) into Thai (DERS-Thai) and evaluate its psychometric properties. Materials and Methods: The DERS-Thai was initially translated by one of the researchers before being re-reviewed. A pre-testing phase was then conducted to preliminarily evaluate the psychometric properties of the DERS-Thai. Subsequently, the testing phase involved 446 participants who completed an online questionnaire platform containing demographic data, DERS-Thai, the Emotion Regulation Scale (ERQ), and the Depression Anxiety Stress Scale 21 (DASS-21). The factor structure was then evaluated, along with its concurrent and criterion validity, as well as its internal consistency. Results: DERS-Thai demonstrated acceptable content validity (I-CVI = 0.8 to 1.0, S-CVI/Ave = 0.85). In the testing phase with 446 participants (mean age = 29.19, SD = 8.50), predominantly female (81.8%), and mostly residing in central Thailand (81.31%), the original model did not fit well. After modification, fit indices were improved. DERS-Thai showed a negative correlation with ERQ and a moderate to strong correlation with DASS-21. Known-group analysis revealed significant differences in DERS-Thai scores between DASS-21 groups (p-value &lt; 0.001). The scale exhibited excellent internal consistency (α = 0.94, ω = 0.96). Conclusion: The DERS-Thai has demonstrated appropriate psychometric properties for assessing emotion regulationskills in individuals.

Knowledge of development during pregnancy and the transition to parenthood: Psychometric properties of the Domains of Development Instrument

Researchers and practitioners need robust measurement tools for evaluating knowledge of child development to better support parents and their children during pregnancy and the transition to parenthood. We addressed this need by evaluating the psychometric properties of the Domains of Development Instrument (DoDI) for measuring knowledge of developmental milestones from birth to 3 years. We evaluated four types of validity evidence for the DoDI: test content, response processes, internal structure, and relations to other variables. We convened an expert panel to evaluate test content and conducted cognitive interviews with mothers to evaluate response processes. We also collected responses from a sample of 418 English-speaking pregnant women to evaluate internal structure and relations to other variables. We observed content validity and response process validity, as well as the predicted internal structure, internal consistency, test–retest reliability, and convergent validity. We conclude with recommendations for future research with the DoDI.

Adapting and validating a game-based testing instrument for measuring nature connectedness in young Chinese children

This study aimed to adapt and validate a Canadian-developed instrument for measuring nature connectedness among young children in China. Nature connectedness, which encompasses emotional, cognitive, and experiential relationships with the natural environment, is linked to various positive outcomes in children, including well-being, eco-friendly behaviors, and academic success. However, existing instruments, which often rely on self-reports, face challenges when applied to young children due to dependence on introspective and expressive abilities and issues with cultural relevance across diverse settings. To address these limitations, this research adapted and validated a game-based instrument through three steps: adaptation for cultural relevance and linguistic accuracy, expert review for content validity, and empirical testing for construct validity. The initial adaptation was informed by a pilot study with 38 children in Hangzhou, which led to further modifications based on feedback. The adapted Chinese version was tested with 406 kindergartners from Hangzhou and Shanghai, demonstrating good reliability and validity in measuring nature connectedness in this population. Findings indicate that the adapted instrument effectively captures the dimensions of nature connectedness among young Chinese children, validating its feasibility of adapting for use in non-Western contexts. This research underscores the importance of culturally sensitive tools in environmental psychology and education, offering a valuable methodology for understanding and enhancing children’s connections with nature across different cultural backgrounds. The study contributes to developing educational strategies and environmental policies to foster a deep, enduring relationship between children and the natural world.

Nursing outcomes and social support intervention for diabetes self-management: consensus study

Highlights Self-management of type 2 diabetes allows for better health outcomes, maintains independence, and improves quality of life for longer periods of time. Nursing interventions help professionals accurately assess the health status and outcomes of the target population while providing scientific evidence. The nursing professional is a significant source of social support in the self-management of diabetes mellitus. The outcomes achieved by patients are the most important indicators of quality in health care, allowing clarifying nursing knowledge and determining the effectiveness of care. Introduction: Diabetes mellitus is one of the most prevalent chronic noncommunicable diseases in the world. Objective: To validate by expert consensus the Nursing Outcomes Classification (NOC) self-management: diabetes (1619) and social support (1504), as well as to validate the intervention of social support for adults in the self-management of type 2 diabetes mellitus (DM2). Materials and Methods: A consensus study. Several phases were delimited for validation: the first was to validate the results and indicators; the second was to construct and validate the conceptual and operational definitions; and the magnitude of the selected indicators; and the third was to design and validate the intervention of social support for adults in the self-management of DM2. Results: 28 indicators were selected and validated by experts out of the 44 that make up the nursing outcome of self-management: diabetes, and 9 indicators out of the 12 that make up the social support outcome, both with a Content Validity Index (CVI) of 0.98. As for the intervention, a social support intervention was designed for the self-management of DM2, individualized, and made up of 4 sessions. The components of the intervention include generalities of DM2, healthy life habits, safe care, and emotional support. Discussion: Nursing professionals must evaluate people who experience diabetes, and their capacity for self-management and social support in order to provide appropriate interventions and evaluate their effectiveness. Conclusions: The study significantly evidenced the validation of the two nursing outcomes and their respective indicators, added to the conceptual and operational definitions, and their magnitude.

An exploratory study of nursing tasks that induce physical and mental stress among hospital nurses

BackgroundNursing tasks are major contributing factors of nurses' stress. Identifying these stress-inducing tasks by hospital and department is the first step in devising practical strategies to address this issue. ObjectivesThis study aimed to develop a nursing task list by categorizing nursing tasks and identifying the ones that induced physical and mental stress among hospital nurses. MethodsThis descriptive exploratory study was conducted. In the first phase, the nursing task list was formulated based on a literature review and an expert content validity verification. In the second phase, the stress-inducing (both physical and mental) nursing tasks in different departments at two types of hospitals were investigated from 775 nurses. The data were analyzed using descriptive statistics, t-test, χ2 test and ANOVA performed using SPSS/WIN 26.0. ResultsThe nursing task of “exercise and position change” was identified to cause the highest physical stress across all five departments in both advanced general hospitals and general hospitals. Similarly, the nursing task “explanation of patients' condition upon request from the patients' family members” induced the greatest mental stress in both advanced general hospitals and general hospitals. Finally, “substitution for physicians: prescription” was identified as the greatest mental stress-inducing nursing task in general hospitals. ConclusionBased on a nursing task list developed, we determined which nursing tasks induce physical and mental stress in different departments at two types of hospitals. This foundational work will be crucial for exploring practical strategies to relieve nurses' stress.

Brain Death Knowledge and Attitudes Among Fourth-Year Medical Students at Umm Al-Qura University.

Background Despite clear definitions of brain death, students and medical professionals may have varying understandings. This study investigated the knowledge and attitudes of medical students regarding brain death. Methods A cross-sectional survey was administered to 142 fourth-year medical students at Umm Al-Qura University. The survey used single-choice and Likert scale questions to assess knowledge of brain death definition, diagnosis procedures, and student attitudes. Prior to administration, the questionnaire underwent content validation by experts in medicine, ethics, and public health. Results A significant proportion of students lacked knowledge of the legal definition of brain death in Saudi Arabia (26.1%), brain death diagnostic procedures (43.7%), and prerequisites for declaring brain death (38%). While some students expressed confidence in diagnosing brain death, concerns about misdiagnosis were also present. Conclusion Fourth-year medical students in this study demonstrated significant knowledge gaps regarding brain death. Medical education programs may need to be revised to provide more comprehensive training on brain death and its implications. Additionally, public awareness campaigns could improve understanding and facilitate informed decision-making about organ donation. Further research, including multicenter studies, is warranted to confirm these findings and guide educational interventions.

Examining the content validity of the Comprehensive Assessment of Functioning for Mental Illness-Subjective Version (CAMI-S) with reference to the framework of the International Classification of Functioning, Disability, and Health (ICF).

To support the achievement of life goals and social participation of persons with mental illness, based on the World Health Organization's International Classification of Functioning, Disability, and Health (ICF), we generated items, identified domains, and examined the content validity of the Comprehensive Assessment of Functioning for Mental Illness-Subjective Version (CAMI-S). The purpose was to assess patients' strengths and weaknesses by incorporating the patient and public involvement perspective. Focus group interviews on the items to be included were conducted with Group A. A draft scale was constructed by extracting articles mentioning factors for social participation and recovery for each ICF component from PubMed. Group B participants rated themselves using the draft and highlighted items they considered inappropriate. Experts then rated the importance of the items through the Delphi method. Lastly, Group C participants evaluated whether the draft scale would help in understanding their strengths and weaknesses. The interviews revealed subjective experience items. The draft scale had 81 items (physical and mental functions, 10; activities, 23; participation, 24; environment, 12; individuals, six; and subjective experience, six). Through the Delphi method, the number of items was reduced to 34 in six domains. Most participants (N = 50) indicated that it helped them ascertain patients' strengths and weaknesses (mean = 2.11 ± .714). Completion time for the scale was 56 min, including the 60-item face sheet (20-110 min). The CAMI-S helped participants ascertain patients' strengths and weaknesses. Its reliability and validity will be verified through a large-scale survey in the future.

Development and Evaluation of the DMIND Questionnaire: Preparing for AI Integration into an Effective Depression Screening Tool

Objective: Thailand’s mental health crisis is exacerbated by high demand and a shortage of mental health professionals. The research objective was to develop and validate the Detection and Monitoring Intelligence Network for Depression (DMIND) questionnaire, designed to be culturally relevant and easily administered in clinical settings. Crafted with expert input, items specifically conducive to artificial intelligence (AI) analysis were selected to facilitate the future development of an AI-assisted depression scoring model. This approach underscores the tool’s dual utility in both human-led and technology-enhanced diagnostics. Materials and Methods: We enrolled 81 participants from psychiatric and tertiary care hospitals in Bangkok. Participants were assessed using the DMIND questionnaire, followed by the Hamilton Depression Rating Scale (HDRS-17). Statistical analyses included the content validity index (CVI), Cronbach’s alpha, Pearson’s correlation coefficient, Cohen’s kappa, and receiver operating characteristic (ROC) analysis. The Liu method, Youden index, and nearest neighbor method were used to determine the optimal cut-off point Results: The DMIND questionnaire showed strong validity, with an item-level CVI (I-CVI) and scale-level CVI (S-CVI) exceeding 1.0, indicating strong consensus on its relevance and utility. The tool also demonstrated high internal consistency (Cronbach’s alpha = 0.96). ROC analysis showed an AUC of 0.88, indicating high accuracy in depression screening. An optimal cut-off score of 11.5 was identified, balancing predictive value and sensitivity. Conclusion: The DMIND questionnaire represents a significant advancement in innovative mental health diagnostics, addressing unmet clinical needs by providing accurate and efficient assessments capable of AI integration for further enhancing mental health service delivery in Thailand.

Postintensive care syndrome: Development and psychometric validation of a knowledge test.

Postintensive care syndrome (PICS) is a combination of short-, medium-and long-term morbidities that occur in patients discharged from the Intensive care unit (ICU). ICU professionals have a crucial role in managing and understanding the PICS. This study aimed to develop the PICS Knowledge Test (PICS-KT), which measures ICU professionals'awareness and knowledge levels regarding PICS, and to determine its validity and reliability. The databases were searched in detail, scientific research related to PICS was analyzed, and the draft scale was created accordingly. A total of 117 doctors and nurses who had been working in the ICU for at least 6 months were included in the study. For the validity and reliability analysis of the test, content validity ratio, item difficulty index, item discrimination index values and Cronbach α were examined. The Cronbach's α reliability coefficient for the 46-item PICS-KT is 0.93, indicating high reliability. Scores range from 0 to 46, with 32 or higher considered successful, suggesting adequate knowledge of PICS among ICU professionals. Scores of 14 or less indicate minimal knowledge. Those with scores between 14 and 32 possess some knowledge but need improvement. PICS-KT assesses knowledge in four main areas: general information, risk factors/causes, symptoms and findingsand interventions. ICU professionals show high awareness of interventions for preventing and treating PICS, as indicated by a high mean score in the interventions subdimension. The PICS-KT is crucial in assessing healthcare professionals'understanding of the various short-, medium-and long-term morbidities associated with PICS. The study ensures that the test is a robust and dependable instrument for evaluating ICU professionals'knowledge about PICS.

Development and testing of a tool to assess parental care for children with mental illness (PCCMI)

Background: Involving parents in mental health treatment services can empower parents to manage their child’s illness. We conducted this study to develop a tool to assess parental care for children with mental illness. Materials and Methods: The present study was conducted in five phases that included in-depth interviews with parents in the outpatient department (OPD), focus group discussions (FGDs) with parents in an in-patient setting, and with a multidisciplinary team, item development, and the assessment of psychometric properties of the tool. Results: Parental care for children with mental illness (PCCMI) has 50 items derived from a thematic analysis of in-depth interviews of 31 parents and 2 FGDs with eight parents admitted at CPC and eight mental health professionals experienced in child and adolescent psychiatry. It is a 5-point Likert scale. The tool showed a high item-level Content Validity Index (I-CVI range: 0.8–1.0) and a high Scale Content Validity Index (S-CVI = 0.91). The test–retest method was used to calculate reliability. A total of 38 parents were included in the test–retest method. The mother and father’s mean age and standard deviation (SD) scores were 39.7 ± 5.8 and 45.1 ± 4.9, respectively. Most parents’ education level is above graduation (mothers: 86.8% and fathers: 86%). Around 63% of mothers were housewives and had normal pregnancies. The single measure two-way mixed absolute agreement intraclass correlation coefficient (ICC) value for 38 subjects was 0.96 with a 95% confidence interval (CI: 0.90–0.95), indicating high reliability. Conclusion: PCCMI has high I-CVI and S-CVI and good ICC test–retest reliability. This tool will help mental health professionals in the formal assessment of parental care for children with mental illness and provide the intervention to address issues related to the same.

Psychometric Properties of the EQ-5D-5L in Patients with Alopecia Areata.

For many decision makers in Health Technology Assessment the EQ-5D-5L is the standard measure of health-related quality of life (HRQL). However, evidence has shown the limitations of the measure in certain disease areas, including dermatology. Alopecia areata (AA) is associated with a significant HRQL impact, partly due to the emotional impact of hair loss. This study explores the psychometric properties of the EQ-5D-5L in people with AA in reference to the short-form 36 version 2 (SF-36v2), the Alopecia Areata Patient Priority Outcomes (AAPPO), the Severity of Alopecia Tool (SALT) and the Patient Global Impressions of Change (PGI-C). Data from participants with AA enrolled in the ALLEGRO-2b/3 trial (NCT03732807) of ritlecitinib were analysed. Participants completed the AAPPO measure (an AA-specific measure assessing emotional symptoms and activity limitations), PGI-C, EQ-5D-5L and SF-36v2 across 48-weeks of follow up. Extent of scalp hair loss was assessed using the SALT. Ceiling effects, known groups validity, convergent validity and responsiveness were examined. Known groups were defined by SALT score and a PGI-C defined response from baseline. Exploratory factor analysis was also performed. Data were available from 612 adult participants. Ceiling effects were observed for the EQ-5D-5L (55.3-61.2%) and analyses suggested that the EQ-5D did not capture important differences between patients that the SF-36v2 did. The EQ-5D-5L very weakly correlated with SALT score, whereas the AAPPO correlated more strongly with the extent of hair loss. Compared with the EQ-5D-5L, the AAPPO was better able to discriminate between known groups defined by SALT and PGI-C. An exploratory factor analysis suggested that the EQ-5D-5L had limitations in content validity compared with the AAPPO. The EQ-5D-5L may not adequately measure the burden of AA on patients' HRQL. Insensitivity to the burden of AA suggests that the EQ-5D-5L may not measure treatment-related benefit with hair regrowth. Data from other measures could be considered if they are shown to be more relevant.

A method for rapid assessment of visual ergonomics and lighting conditions (RAVEL): An in-depth development and psychometrics study.

In workplaces heavily reliant on visual tasks, various factors can significantly influence an individual's performance, necessitating the use of reliable tools to identify and mitigate these factors. This study aimed to develop a swift assessment method for visual ergonomics and lighting conditions, evaluating its validity in real-world scenarios. The questionnaire's content validity was determined by a panel of experts using the content validity ratio (CVR) and content validity index (CVI). Construct validity was assessed through exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and latent class analysis (LCA). Internal consistency was measured using Cronbach's alpha coefficient. The RAVEL index, derived from the calculated effect coefficients of items, classified total scores through receiver operator curves (ROCs). The rapid assessment method, comprising two parts with 30 items, demonstrated acceptable reliability with CVR, CVI, and Cronbach's alpha coefficient (α) at 0.75, 0.87, and 0.896, respectively. The EFA on the first part's 22 items identified three factors, confirmed by CFA. The LCA on the second part's eight items revealed that a two-class model best fit the data, with Bayesian information criterion (BIC) = 24249, 17, Akaik information criterion (AIC) = 2179.89, and an entropy R-squared of 0.83, indicating appropriate subject classification based on the model. The RAVEL score was categorized into three levels, with optimal cut points of 55 and 63. In conclusion, the study demonstrated that this method based on visual ergonomics serves as a rapid and reliable tool for assessing visual ergonomic risks of display users in the workplace.

Simplified Chinese Trauma Advanced Practice Nurses' Core Competency Scale: A development and psychometric validation study

BackgroundThe core competency of trauma advanced practice nurses (APNs) is directly related to the quality of trauma nursing work. ObjectivesTo develop an instrument to measure trauma APNs' core competency and examine its psychometric properties. DesignA cross-sectional psychometric validation study. ParticipantsA total of 762 trauma nurses recruited from several tertiary hospitals in 14 different provinces of China between June 2023 and May 2024 provided valid data for analysis. MethodsThe Simplified Chinese Trauma Advanced Practice Nurses' Core Competency Scale (TAPNCCS-SC) was developed through five steps. Step 1) Creation of the operational definition: Based on the onion model, an operational definition of core competencies for trauma nurses is proposed. Step 2) Item generation: Based on the theoretical model, literature review, semi-structured interviews, and Delphi consultation, a preliminary scale was developed. Step 3) Item content validation: 6 experts reviewed items for content validity; Step 4) Pilot study: 21 nurses were selected to test the readability of the preliminary scale; and Step 5) Psychometric evaluation: Item analysis, content validity, exploratory and confirmatory factor analyses, convergent validity, internal consistency reliability, and half-reliability were conducted. ResultsThe TAPNCCS-SC consists of 34 items and three dimensions (knowledge and skills, professional competencies, and occupational qualities). The explained variance of the 3-factor was 81.86 %. The CFA showed an acceptable-fitting 3-factor model (χ2/df = 3.653, RMSEA = 0.088, SRMR = 0.402, CFI = 0.920, IFI = 0.920, and TLI = 0.914). For convergent validity, AVE was 0.784–0.804 and CR was 0.974–0.980. The internal consistency and split-half reliability for the total scale were 0.991 and 0.945, respectively. The I-CVI ranged from 0.83 to 1. ConclusionsThe proposed scale exhibits high reliability and validity and is suitable for assessing the core competency of trauma APNs, which can help nursing managers plan relevant training and enhance trauma care competency.
