Abstract
BACKGROUND Sarcopenia, prevalent in patients with cancer, negatively affects quality of life. However, generic tools are unable to capture the minor effects of sarcopenia on quality of life. The short-form version of the Sarcopenia Quality of Life (SF-SarQoL) questionnaire was developed as an efficient tool to assess the impact of sarcopenia on quality of life in older adults. However, its clinimetric properties in patients with cancer remain unknown. PURPOSE This study was designed to examine the clinimetric properties of the Chinese SF-SarQoL in patients with colorectal cancer, particularly with regard to its ability to detect changes in quality of life. METHODS A longitudinal survey was conducted using the SF-SarQoL and other questionnaires on 408 patients with colorectal cancer planning to undergo surgery. Follow-up was subsequently conducted on 341 of these patients 1 month after surgery. The clinimetric properties of the SF-SarQoL were examined, including reliability (internal consistency), validity (construct validity, concurrent validity), sensitivity (ability to detect changes, discriminative ability), and floor and ceiling effects. RESULTS The internal consistency of the SF-SarQoL was found to be acceptable (Cronbach's alpha = .94 and McDonald's omega = .94). Strong scalability of the total score and each item was confirmed using Mokken analysis. Concurrent validity analyses indicate the SF-SarQoL is significantly correlated with muscle-related and health-related questionnaire scores. The SF-SarQoL showed adequate sensitivity due to its good ability to detect changes in quality of life with a moderate effect size (Cohen's d = 0.56) and discriminate between sarcopenic and nonsarcopenic patients (area under the curve = 0.73, 95% CI [0.66, 0.79]) using receiver operating characteristic curve analyses. No floor or ceiling effects were observed. CONCLUSIONS The Chinese SF-SarQoL exhibits good clinimetric properties in preoperative patients with colorectal cancer and is sufficiently sensitive to capture changes in quality of life after surgery.

Abstract
BACKGROUND Deeper comprehension of eating-related behaviour (how and why people eat) can reveal new aspects to support health and prevent type 2 diabetes (T2D). However, such research is largely missing in aging men. AIM The aim was to investigate suitability of the Three-Factor Eating Questionnaire-R18 (TFEQ-R18) in Finnish aging men which is widely used to examine factors: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). METHODS Study population consisted of 420 men aged 50-75, who completed the TFEQ-R18 at the baseline of the T2D-GENE lifestyle intervention study. Inclusion criteria were impaired fasting glucose (IFG) and body mass index ≥25 kg/m2. Confirmatory factor analysis was used to study psychometrics (reliability, validity, and model fit) and factor structure of TFEQ-R18. RESULTS The items loaded to the three factors (CR, UE, EE) as in previous studies, except two items at CR factor and one at UE factor, which were therefore omitted. UE was also discovered split into two sub factors (named as 'craving' and 'loss-of-control'), UE being a higher-order (h) factor. The resultant revised version was named as Three-Factor Eating Questionnaire Revised to 15-items with higher-order factor (TFEQ-R15h). CONCLUSION The original 18-item version of the TFEQ was not optimal in the population consisting of Finnish aging men with elevated T2D risk. A modified 15-item version of the TFEQ could be used to describe EB in this population instead.

Abstract
BACKGROUND This study is aimed to perform the translation and cultural adaptation of the Neonatal Palliative Care Attitude Scale (NiPCAS) and evaluation of its psychometric properties with Portuguese neonatal nurses. METHODS The research started with a scoping review that allowed the identification of the NiPCAS. It was a methodological study with a quantitative approach. The semantic equivalence of the items was adjusted with the participation of 20 neonatal nurse experts. They performed facial and quantitative content validation. Psychometric validation of the NiPCAS was performed on a nonprobability nurses sample (n = 283) in 13 level 3 neonatal units between July 2021 and February 2022. Confirmatory factor analysis using the polychoric correlation matrix was performed to estimate factor validity using the "lavaan" package for R statistical software. Internal consistency was estimated using Cronbach's alpha coefficient, and item sensitivity was assessed using the asymmetry and kurtosis coefficients. Empirical indices were considered: chi-square over degrees of freedom; comparative fit index; normed fit index; Tucker-Lewis index, and root mean square error of approximation; average extracted variance and composite reliability were used to assess convergent validity. RESULTS Asymmetry and kurtosis were <|3| and <|7|, respectively, suggesting psychometric sensitivity. The convergent validity of the factors was: F1, FCF1 = 0.90 and for F2, FCF2 = 0.80, and a lower value for F3, FCF3 = 0.40. According to the squared correlation criterion average variance extracted (AVE) between the factors, there was no discriminant validity for F1 and F2, but there was discriminant validity for F1, F3, F2, and F3. SIGNIFICANCE OF RESULTS This instrument has implications for providing end-of-life care to newborns and their families. The use of this instrument reveals several barriers and facilitating elements inherent in the organization and culture of the facility and nursing education.

Evaluation of the test-retest and inter-mode comparability of the Impact of Vision Impairment questionnaire in people with chronic eye diseases. Graefes Arch Clin Exp Ophthalmol 2024; 262:1933-1943. [PMID: 38180569 PMCID: PMC11106107 DOI: 10.1007/s00417-023-06334-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Revised: 11/03/2023] [Accepted: 11/30/2023] [Indexed: 01/06/2024] Open
Abstract
PURPOSE The main objective of this study is to assess the test-retest and inter-administration mode reliability of the Impact of Vision Impairment profile (IVI), a common patient-reported outcome measure (PROM) for people with chronic eye diseases. METHODS The IVI was administered to adult patients with stable, chronic eye diseases two to four times per participant (average intervals between administrations 12 to 20 days; maximum two phone interviews, paper administration, electronic administration) by two trained interviewers. Rasch models were fit to the data. Intra-class correlation coefficients (ICCs), mean differences and Cronbach's alpha between test-retest administrations (two phone interviews) and inter-mode comparisons were calculated. RESULTS Two hundred-sixteen patients (mean age 67 ± 12 years, 40% male) were included in the study. The IVI met all psychometric requirements of the Rasch model, and the division into the domains of functional items (IVI_F) and emotional items (IVI_E) corresponded to the German validation study. ICCs (all for IVI_F and IVI_E, respectively) for the retest administrations were 0.938 and 0.912, and 0.853 and 0.893 for inter-mode comparisons phone/paper, 0.939 and 0.930 for phone/electronic, and 0.937 and 0.920 for paper/electronic (all p < 0.01). Mean differences (all for IVI_F and IVI_E, respectively) for the retest administrations were 2.8% and 0.7% and ranged from 2.0% to 6.2% and from 0.4 % to 4.9% between administration modes. Cronbach's alpha ranged from 0.886 to 0.944 for retest and inter-mode comparisons. CONCLUSION Due to the high test-retest reliability and the almost equally high comparability of different modes of administration of the IVI, the study endorses its use as a robust PROM to capture vision-related quality of life. Our results further support the use of the IVI as an endpoint in clinical trials and may simplify implementing it in both clinical trials or real-world evidence generation by offering multiple administration modes with high reliability.

Abstract
Chronic pain populations exhibit greater prevalence of benzodiazepine (BZD) prescription (vs. the general population) and greater likelihood of BZD use not as prescribed and dependence symptoms. Individuals report taking BZDs for pain relief, potentially contributing to maintenance/escalation of BZD use and hazardous couse with prescription opioids. Identifying cognitive factors underlying pain-BZD use relations represents a critical step toward understanding the role of pain in BZD use trajectories. Outcome expectancies for substance-related analgesia have been implicated in pain-substance use comorbidity (e.g., alcohol), and there is reason to believe these processes may extend to BZD use. The present study aimed to examine psychometric properties of a newly adapted Expectancies for Benzodiazepine Analgesia (EBA) scale and probe associations between EBA scores and prescription opioid use behaviors. Participants were 306 adults (38.9% females) endorsing chronic pain and current BZD prescription who completed an online survey. Results provided initial support for psychometric validity of the EBA: evidence of single-factor structure with good model fit (Bollen-Stine bootstrap p = .101), excellent internal consistency (α = .93), and evidence of concurrent validity via correlations with pain variables, likelihood of BZD use not as prescribed, BZD dependence symptoms, and self-reported BZD use for pain relief. Exploratory findings among participants prescribed opioids indicated positive covariation between EBA scores and behaviors associated with higher risk opioid use. This is, to our knowledge, the first study to assess analgesia expectancies for BZD use. BZD analgesic expectancies warrant further study as a treatment target in comorbid pain and BZD use.

Abstract
Delay discounting (DD) assessments offer a wide variety of procedures to suit specific clinical and research needs. This study compared the reliability and validity of two DD tasks: (a) an adjusting amounts task presented on a computer (AAC) and (b) the 21-item Monetary Choice Task, which was administered online (MCT). Participants were 1,573 Spanish young-adults reporting past-month substance use. Measures included quantity and severity of drug use (i.e., cigarette smoking, cannabis, alcohol) and two DD assessments (i.e., AAC, MCT). Reliability was assessed using both the classical test and item response theory. Correlations and linear regressions examined the validity of both DD tasks in relation to substance use. The MCT showed higher internal consistency than the AAC (α = .941 vs. α = .748). AAC precision was adequate for moderate levels of discounting (θ values between -2 and +2), but the MCT showed superior reliability at low, moderate, and high levels of discounting (θ values between -1 and +1.5). Both DD tasks showed more significant correlations for alcohol-related measures (|rs| ranged between .053 and .093) compared to cigarettes and cannabis. The incremental validity of DD tasks in relation to nicotine dependence (AUClogd: β = -.664, 95% CI [-1.256, -.071]) and alcohol problems (AUClogd: β = -3.098, 95% CI [-5.209, -.988]) was only supported for the AAC. The MCT was more reliable than the AAC for measuring impulsive choice in young adult substance users. Nevertheless, the AAC may serve as a valid marker of nicotine dependence and alcohol problems.

Abstract
Cognitive diagnosis models (CDMs) provide a powerful statistical and psychometric tool for researchers and practitioners to learn fine-grained diagnostic information about respondents' latent attributes. There has been a growing interest in the use of CDMs for polytomous response data, as more and more items with multiple response options become widely used. Similar to many latent variable models, the identifiability of CDMs is critical for accurate parameter estimation and valid statistical inference. However, the existing identifiability results are primarily focused on binary response models and have not adequately addressed the identifiability of CDMs with polytomous responses. This paper addresses this gap by presenting sufficient and necessary conditions for the identifiability of the widely used DINA model with polytomous responses, with the aim to provide a comprehensive understanding of the identifiability of CDMs with polytomous responses and to inform future research in this field.

Abstract
AIM Nurses play a crucial role within medical institutions, maintaining direct interaction with patient data. Despite this, there is a scarcity of tools for evaluating nurses' perspectives on patient information security. This study aimed to translate the Information Security Attitude Questionnaire into Chinese and validate its reliability and validity among clinical nurses. DESIGN A cross-sectional design. METHODS A total of 728 clinical nurses from three hospitals in China participated in this study. The Information Security Attitude Questionnaire (ISA-Q) was translated into Chinese utilizing the Brislin two-way translation method. The reliability was assessed through internal consistency coefficient and test-retest reliability. The validity was determined through the Delphi expert consultation method and factor analysis. RESULTS The Chinese version of ISA-Q consists of 30 items. Cronbach's α coefficient of the questionnaire was 0.930, and Cronbach's α coefficient of the six dimensions ranged from 0.781 to 0.938. The split-half reliability and test-retest reliability were 0.797 and 0.848, respectively. The content validity index (S-CVI) was 0.962. Exploratory factor analysis revealed a 6-factor structure supported by eigenvalues, total variance interpretation, and scree plots, accounting for a cumulative variance contribution rate of 69.436%. Confirmatory factor analysis further validated the 6-factor structure, demonstrating an appropriate model fit. CONCLUSION The robust reliability and validity exhibited by the Chinese version of ISA-Q establish it as a dependable tool for evaluating the information security attitudes of clinical nurses. IMPLICATIONS FOR NURSING PRACTICE The Chinese iteration of the ISA-Q questionnaire offers a profound insight into the information security attitudes held by clinical nurses. This understanding serves as a foundation for nursing managers to develop targeted intervention strategies aimed at fortifying nurses' information security attitudes, thereby enhancing patient safety.

Assessing intrinsic capacity in Taiwan: Initial psychometric properties of the Integrated Care for Older People Screening Tool for Taiwanese (ICOPES-TW). BMC Geriatr 2024; 24:477. [PMID: 38822234 PMCID: PMC11141031 DOI: 10.1186/s12877-024-05071-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Accepted: 05/13/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND The World Health Organization (WHO) proposed the concept of intrinsic capacity (comprising composite physical and mental capacity) which aligns with their concepts of healthy aging and functional ability. Consequently, the WHO promotes the Integrated Care for Older People (ICOPE) framework as guidance for geriatric care. Consequently, each government should have a screening tool corresponding to ICOPE framework to promote geriatric care. The present study examined the initial psychometric properties of the Taiwan version of ICOPE (i.e., ICOPES-TW). METHODS Older people (n = 1235; mean age = 72.63 years; 634 females [51.3%]) were approached by well-trained interviewers for participation. A number of measures were administered including the ICOPES-TW, WHOQOL-AGE (assessing quality of life [QoL]), Clinical Frailty Scale (assessing frailty), Barthel Index (assessing basic activity of daily living [BADL]), and Lawton Instrumental Activities of Daily Living Scale (assessing instrumental activity of daily living [IADL]). RESULTS The ICOPES-TW had a two-factor structure (body functionality [eigenvalue = 1.932] and life adaptation [eigenvalue = 1.170]) as indicated by the results of exploratory factor analysis. Internal consistency of the ICOPES-TW was low (Cronbach's α = 0.55 [entire ICOPES-TW], 0.45 (body functionality factor), and 0.52 (life adaptation factor). ICOPES-TW scores were significantly (i) positively correlated with age (r = 0.321), IADL (r = 0.313), and frailty (r = 0.601), and (ii) negatively correlated with QoL (r=-0.447), and BADL (r=-0.447), with all p-values < 0.001. CONCLUSION The ICOPES-TW could be a useful screening tool for healthcare providers to quickly evaluate intrinsic capacity for Taiwanese older people given that it has moderate to strong associations with age, BADL, IADL, QoL, and frailty.

Abstract
For a multi-dimensional measure of positive youth development (PYD), its factor structure should be invariant across groups and over time. This study examined the factorial validity of the 44-item short form of the "Chinese Positive Youth Development Scale" (CPYDS-SF) that assesses 15 dimensions of PYD attributes. Using two waves of longitudinal data with a one-year interval in between, this study examined the factor structure of the scale and whether the structure is invariant between gender groups and across time. The data were collected from 3,328 adolescents at Wave 1 and 3,638 adolescents at Wave 2, with a matched sample of 2,905 adolescents (mean age = 12.57 ± 0.72 at Wave 1; 49.54% girls). Confirmatory factor analysis revealed that the 15-factor structure fitted the data well. The findings of invariance tests further supported this structure's invariance across gender and time, indicating a stable factor structure of CPYDS-SF among Chinese adolescents. These findings suggest that CPYDS-SF can be used to examine gender differences and the longitudinal development of PYD qualities among Chinese adolescents.

Abstract
BACKGROUND The PHQ-4 is an ultrabrief screening test for depression and anxiety symptoms. The psychometric properties of this test among the population in Chile are unknown. This study was aimed to determine the factor structure of the PHQ-4 in the adult population in Chile, and to assess its measurement invariance across different groups. METHODS The study considered a nationally representative sample of 10921 people aged 18 and above, in Chile in 2021. Exploratory and confirmatory factor analysis were conducted, and configural, metric, scalar, and strict measurement invariance were assessed. RESULTS The two-factor structure of the PHQ-4 supported the two underlying constructs of depression and anxiety. This model explained 67% of the variance and had excellent fit (CFI: 0.9999; TLI: 0.9994; RMSEA: 0.0107; SRMR: 0.0022). Strict measurement invariance held across gender, age, area of residence, household income quintile, immigrant or host population, and indigenous or non-indigenous population (ΔCFI<0.01). CONCLUSION The PHQ-4 can be used to assess depressive and anxiety symptoms in population studies, and as a screening test for depression and anxiety in public mental health programs in Chile.

Abstract
PURPOSE A rise in strokes worldwide means that the number of people affected by aphasia is increasing. Early and accurate diagnosis of aphasia is crucial for recovery. Presently, there are no dedicated screening tests tailored for evaluating aphasia in Serbian-speaking individuals. This paper presents and describes the psychometric properties of the Serbian Aphasia Screening Test (SAST), a novel aphasia screening tool designed specifically for Serbian speakers. This initiative fills the gap in aphasia assessment tools for the Serbian population, providing a comprehensive and culturally sensitive approach to the evaluation of language disorders. METHOD Data using the SAST were collected from 240 participants: 120 Serbian speakers with aphasia after stroke compared to 120 neurotypical individuals. The assessment included the following subtests: conversation, verbal automatized sequences, auditory comprehension, visual confrontation naming, responsive naming, repetition of words, repetition of sentences, oral word reading, oral sentence reading, reading comprehension, and writing. The main objectives were to ascertain the psychometric qualities of the SAST, including inter-rater reliability of scoring, test-retest reliability, reliability of the individual subtests, overall test reliability, and inter-correlations among subtests. Additionally, the study evaluated the discriminatory capability of the SAST in distinguishing between individuals with aphasia and neurotypical controls, as well as between individuals with different types of aphasia. RESULTS The findings revealed that the SAST has excellent inter-rater reliability, test-retest reliability, and internal consistency. There were statistically significant differences between individuals with aphasia and neurotypical controls on all SAST subtests. Furthermore, the study identified significant differences in language profiles among participants with different types of aphasia. The significant correlations between scores on the SAST and on the Boston Diagnostic Aphasia Examination (BDAE) suggest good convergent validity of the SAST. CONCLUSIONS The results underscore the robust psychometric properties of this novel screening assessment (SAST) and its ability to effectively discriminate between diverse linguistic abilities within different aphasia syndromes in Serbian speaking individuals.

Abstract
BACKGROUND An accurate perception of death risk is a prerequisite for advanced cancer patients to make informed end-of-life care decisions. However, there is to date no suitable scale to measure death risk perception. This study was to develop and psychometrically test the death risk perception scale (DRPS) for advanced cancer patients. METHODS Process of instrument development and psychometric evaluation were used. First, qualitative research, a literature review, brainstorming, a Delphi study, and cognitive interviews were conducted to construct a pretest scale of death risk perception. Second, a scale-based survey was administered to 479 advanced cancer patients. Item, exploratory factor, and confirmatory factor analyses were employed to optimize the scale. The Cronbach's alpha was calculated as a reliability analysis. The validity analysis included construct, convergent, discriminant, and content validity values. RESULTS A three-dimension, 12-item scale was developed, including deliberative, affective, and experiential risk perception. The confirmatory factor analysis supported the three-factor model with satisfactory convergent and discriminant validity levels. The Cronbach's alpha coefficient for internal consistency was 0.807 and scale-level content validity index was 0.98. CONCLUSIONS The 12-item DRPS is a reliable and valid instrument for assessing the level of death risk perception in advanced cancer patients. More studies are needed to examine its structure and robustness prior to use.

Abstract
BACKGROUND Almost all patients with Neurofibromatosis type 1 (NF1) develop cutaneous neurofibroma (cNF), benign dermal tumours that have a large impact on the patient's Quality of Life (QoL). The French cNF-Skindex is the first questionnaire to specifically assess cNF-related QoL in patients with NF1. We aimed to adapt and validate a Dutch version of the cNF-Skindex. METHODS The questionnaire was translated using forward and backwards translation, and subsequently administered to a sample of 59 patients on two separate occasions. Feasibility was evaluated by the presence of floor/ceiling effects. Reliability was assessed by evaluating internal consistency and test-retest reliability, by calculating Cronbach's alpha and Spearman's rank correlation coefficients. The EQ-5D-5L and SF-36 were used to evaluate convergent validity, using Spearman's rank correlation coefficients. An exploratory factor analysis was performed to study the data's internal structure. Multivariable linear regression was used to model the relationship between patient characteristics and the cNF-Skindex. RESULTS The Dutch cNF-Skindex demonstrated excellent feasibility and reliability (Cronbach's alpha 0.96, test-retest correlation coefficient 0.88). Convergent validity was confirmed for the EQ-5D-5L and relevant SF-36 scales. All items and subdomains from the original questionnaire were confirmed following exploratory factor analysis. The patient characteristics included in the multivariable linear regression were not significantly associated with the cNF-Skindex score. CONCLUSIONS The Dutch cNF-Skindex displayed excellent psychometric properties, enabling use in the Netherlands.

Abstract
BACKGROUND Fascia iliaca block (FIB) is an effective technique for analgesia. While FIB using ultrasound is preferred, there is no current standardised training technique or assessment scale. We aimed to create a valid and reliable tool to assess ultrasound-guided FIB. METHOD This prospective observational study was conducted in the ABS-Lab simulation centre, University of Poitiers, France between 26-29 October and 14-17 December 2021. Psychometric testing included validity analysis and reliability between two independent observers. Content validity was established using the Delphi method. Three rounds of feedback were required to reach consensus. To validate the scale, 26 residents and 24 emergency physicians performed a simulated FIB on SIMLIFE, a simulator using a pulsated, revascularised and reventilated cadaver. Validity was tested using Cronbach's α coefficient for internal consistency. Comparative and Spearman's correlation analysis was performed to determine whether the scale discriminated by learner experience with FIB and professional status. Reliability was analysed using the intraclass correlation (ICC) coefficient and a correlation score using linear regression (R2). RESULTS The final 30-item scale had 8 parts scoring 30 points: patient positioning, preparation of aseptic and tools, anatomical and ultrasound identification, local anaesthesia, needle insertion, injection, final ultrasound control and signs of local anaesthetic systemic toxicity. Psychometric characteristics were as follows: Cronbach's α was 0.83, ICC was 0.96 and R2 was 0.91. The performance score was significantly higher for learners with FIB experience compared with those without experience: 26.5 (22.0; 29.0) vs 22.5 (16.0; 26.0), respectively (p=0.02). There was a significant difference between emergency residents' and emergency physicians' scores: 20.5 (17.0; 25.0) vs 27.0 (26.0; 29.0), respectively (p=0.0001). The performance was correlated with clinical experience (Rho=0.858, p<0.0001). CONCLUSION This assessment scale was found to be valid, reliable and able to identify different levels of experience with ultrasound-guided FIB.

Abstract
BACKGROUND WHO stated the environment is an important factor affecting the development of hospice care. The environment is the sum of factors affecting behavior besides the individual factors. Currently, a scale to comprehensively assess the hospice environment of nurse is still lacking. This study aimed to develop an instrument to investigate the environmental factors affecting hospice care of nurses. METHODS Literature review and a semi-structured interview were conducted to form the items pool of the Hospice Care Environment Scale. Two rounds of Delphi expert consultation were conducted by 16 experts to revise the scale dimensions and entries to form the Hospice Care Environment Scale. A psychometric evaluation was then performed among 530 oncology nurses in a large tertiary oncology hospital in Hubei Province. The 500 valid questionnaires were randomly divided into two groups in a 1:1 ratio, sample 1 (n1 = 250) for item screening and sample 2 (n2 = 250) for quality evaluation of the resulting scale. Item analysis, reliability analysis, validity analysis and acceptability analysis were performed. RESULT The Hospice Care Environment Scale consists of two dimensions and 13 entries. The Cronbach's α coefficient of the Hospice Care Environment Scale was 0.970, and the Cronbach's α coefficient of the two dimensions were 0.952 and 0.969, respectively, with the Item-content validity index and average Scale- content validity index of the scale was both 1.000. The validation factor analysis showed the standardized path coefficients of each item were basically above 0.5, and the factor structure model was stable and suitable. The average completion time of the scale was about 3 min, which had good feasibility. CONCLUSION The Hospice Care Environment Scale to assess the environment of hospice care services, has good content and construct validity and reliability. This scale can provide guidance to evaluate the hospice care environment.

Abstract
Critical illness survivors commonly face impairments, such as intensive care unit-acquired weakness (ICUAW) which is characterized by muscle weakness and sensory deficits. Despite these symptoms indicating potential balance deficits, systematic investigations and validated assessments are lacking. Therefore, we aimed to assess balance function using the Mini-BESTest, evaluate its psychometric properties, and identify associated variables. Balance was assessed post-ICU discharge (V1) and at discharge from inpatient neurorehabilitation (V2) in patients with ≥ 5 days of invasive ventilation. Mini-BESTest measurement characteristics were evaluated in an ambulatory subgroup. A multiple linear regression was conducted. The prospective cohort study comprised 250 patients (34% female, 62 ± 14 years, median ICU stay 55 days). Median Mini-BESTest scores improved significantly from V1 (5 (IQR 0-15)) to V2 (18.5 (10-23)) with a large effect size. Excellent inter-rater and test-retest reliabilities of the Mini-BESTest were observed (ICC = 0.981/0.950). Validity was demonstrated by a very high correlation with the Berg Balance Scale (ρ = 0.90). No floor or ceiling effects were detected. Muscle strength, cognitive function, cerebral disease, critical illness polyneuropathy/myopathy, and depression were significantly associated with balance. Despite significant improvements during the rehabilitation period, balance disorders were prevalent in critical illness survivors. Ongoing therapy is recommended. Due to its excellent psychometric properties, the Mini-BESTest is suitable for use in critical illness survivors.Registration: The study was registered at the German Clinical Trials Register (DRKS00021753, date of registration: 2020-09-03).

Abstract
Tibetan-speaking patients seeking care in predominantly Mandarin-speaking healthcare settings frequently face communication barriers, leading to potential disparities and difficulties in accessing care. To address this issue, we translated, culturally adapted, and validated the Numerical Pain Rating Scale (NPRS) and the Global Rating of Change (GRoC) into Tibetan (NPRS-Tib and GRoC-Tib), aiming to facilitate cross-linguistic and cross-cultural interactions while examining potential challenges in the adaptation process. Using standard translation-backward translation methods, expert review, pilot testing, and validation through a cross-sectional study with a short-term longitudinal component, we engaged 100 Tibetan patients with musculoskeletal trauma for psychometric validation, including 37 women (aged 22-60 years, mean age 39.1 years). The NPRS-Tib and GRoC-Tib exhibited outstanding psychometric properties, with an Intraclass Correlation Coefficient (ICC) of 0.983 for NPRS-Tib indicating superb test-retest reliability, and expert review confirming good content validity for both instruments. A Spearman's correlation coefficient (Rho) of -0.261 (P = 0.0087) revealed a significant, albeit weak, correlation between changes in NPRS-Tib scores and GRoC-Tib scores. The adaptation process also presented notable challenges, including translation discrepancies from translators' diverse backgrounds and levels of expertise, ambiguity in scale options, and the lack of established tools for criterion validity assessment in Tibetan.

Abstract
The aim of this study was to create and validate a ten-item Domain-specific Grit Scale for College Athletic Students (DGSCAS) to assess the level of grit among college athletic students. College athletic students from a single independent college located in a northern city in China (526 participants at time 1 and 589 participants at time 2) were assessed according to the scale. Various analyses were conducted in this study, including exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and measurement invariance analysis across different sex and birthplaces. The results of the EFA revealed two factors: consistency of interests and perseverance of effort. The CFA results demonstrated acceptable fit indices (x2 = 160.048, df = 34, x2/df = 4.707, CFI = 0.983, TLI = 0.978, SRMR = 0.021, and RMSEA = 0.079). The scale exhibited satisfactory convergent validity and discriminant validity. The significant correlation of these factors with the Grit scale provided strong evidence of criterion-related validity. Measurement invariance analysis indicated that the scale performed consistently across different sex and birthplaces. Three limitations and corresponding recommendations were discussed, including sample heterogeneity, the lack of a unified test result as a criterion for predictive validity, and the cross-sectional design of the study. In conclusion, the DGSCAS is a practical and validated instrument that can be used to assess the level of grit among college athletic students in an educational context.

Abstract
The Traffic Locus of Control scale (T-LOC) serves as a measure of drivers' personality attributes, providing insights into their perceptions of potential causes of road traffic crashes (RTCs). This study meticulously evaluated the psychometric properties of the Arabic version of T-LOC (T-LOC-A) among Lebanese drivers. Additionally, the study aimed to explore associations between the T-LOC scale and various driving variables, including driver behavior, accident involvement, and traffic offenses. A cross-sectional study was conducted among Lebanese drivers using a face-to-face approach. The validation of the Arabic version of T-LOC (T-LOC-A) occurred through a two-stage process: translating and culturally adapting T-LOC in the first stage, and testing its psychometric properties in the second stage. Data were collected using a comprehensive self-reported questionnaire in Arabic, covering demographic and travel-related variables, risk involvement, and measures such as the Driver Behavior Questionnaire (DBQ) and T-LOC. Exploratory factor analysis and confirmatory factor analysis were performed to scrutinize the factorial structure of T-LOC. Pearson correlation and chi-square tests were used for continuous and categorical variables, respectively. Two logistic regression analyses were executed to probe associations between T-LOC and involvement in road traffic crashes (RTCs) and T-LOC subscales with the occurrence of traffic offenses. The study included 568 drivers, predominantly male (69%) and aged between 30 and 49 years (42.1%). The findings revealed that T-LOC-A exhibited robust psychometric properties, with excellent reliabilities (α = 0.85) and adherence to the original four-factor structure, encompassing self (α = 0.88), other drivers (α = 0.91), vehicle/environment (α = 0.86), and fate (α = 0.66). The multidimensional structure was statistically supported by favorable fit indices. Gender differences revealed men attributing responsibility to other drivers, while women leaned towards fate and luck beliefs. Regarding driver behavior, the "other drivers" and self-dimensions of T-LOC-A correlated positively with aggressive violations. The fate dimension showed positive associations with aggressive violations and lapses. The "other drivers" subscale correlated positively with errors, and the vehicle/environment subscale with lapses. External T-LOC factors were positively associated with accident involvement, while the "LOC self" factor emerged as a protective element. In terms of traffic offenses, "LOC fate" displayed a positive association, while the "LOC self" factor showed a protective effect. In conclusion, the Arabic T-LOC is a reliable and valuable instrument, suggesting potential improvements in driving safety by addressing drivers' locus of control perceptions.

Abstract
OBJECTIVE To develop a scale to assess the excessive behavior of superfans in celebrity worship and to test its reliability and validity in China. METHODS The scale was developed based on the netnography and interviews of celebrity fans and the existing problematic Internet usage scales. Sample 1 (n = 465) was used for exploratory factor analysis, and Sample 2 (n = 804) was used for confirmatory factor analysis, reliability test, criterion validity, and discriminative validity test. RESULTS There were 36 items in the final scale, including nine factors: impaired social functioning, replacement of real to virtual social relationships, sleep and eating problems, withdrawal, mood alteration, salience, excessive buying, increased craving, and escape from real life. The factor loadings ranged from 0.565 to 0.803. Confirmatory factor analysis showed that the scale was well structured. The reliability of the scale and each factor were satisfactory. The scale showed good discriminant validity in reflecting celebrity worship behavior. In terms of scores, mood alteration was the highest, excessive buying was the lowest, and there were certain gender and age differences. CONCLUSION This study initially identified the main characteristics of excessive celebrity worship behavior among young fans on social media. The developed Chinese scale has good reliability and validity and can be used as a measurement tool.

Abstract
The Experience of Embodiment Scale (EES) is a recently developed instrument that assesses experiences of living in the body. Here, we prepared a novel Greek translation of the EES and examined its psychometric properties. We initially prepared a Greek translation of the EES using a 5-step procedure recommended for test adaptation studies. Next, in a cross-sectional study, we asked a sample of 933 women from Cyprus to complete the Greek EES, alongside additional, previously validated measures assessing body appreciation, psychological well-being (self-esteem, life satisfaction), eating restriction, perfectionism, and internalisation of appearance ideals. Our analyses showed that EES factorial models based on confirmatory factor analysis (CFA) roundly had poor fit. Conversely, models based on exploratory structural equation modelling (ESEM)-which accounts for the fact that EES items cross-load across factors-had adequate fit to the data. Additionally, we found that both higher-order and bifactor-ESEM models that controlled for the uniqueness of negatively worded items had adequate fit. The bifactor-ESEM model had the best fit of all the models tested, and was invariant across ethnicity (Greeks and Greek-Cypriots) and was unaffected by differential item functioning based on age and body mass index. Additionally, construct validity of the final, optimal model was adequate, especially for its G-factor, as indicated by significant associations with additional constructs in expected directions. These results suggest that a bifactor-ESEM model of the Greek EES has adequate psychometric properties. Our work highlights important psychometric issues relating to the manner in which the EES should (or could) be conceptualised and modelled, which should be considered more fully in future work.

Abstract
The assessment of dietary intakes and habits using reliable and youth-specific measurement tools during adolescence is essential. The aim of the present study was to culturally adapt and investigate the psychometric properties of the Persian version of the food preferences questionnaire (Persian-FPQ) among Iranian adolescents. This methodological cross-sectional study was conducted among 452 Persian-speaking adolescents, living in Isfahan, Iran. Translation of the FPQ was performed using forward-backward method. Intra Class Correlation (ICC) and Cronbach's α were used to assess test-retest reliability and internal consistency, respectively. Construct validity was investigated by using exploratory factor analysis (EFA). Divergent validity was determined using correlation analysis with Kessler Psychological Distress Scale (K-10). Known-group validity was assessed based on differences in mean food preference score between boys and girls and different categories of body mass index (BMI). The internal and external reliabilities for the Persian-FPQ were in the range of good to excellent in all domains (Cronbach's α: 0.76-0.96 and ICCs: 0.982-0.998). Boys had higher scores of food preferences than girls, indicating good known-group validity. Construct validity evaluated by EFA led to extraction of seven factors ("Vegetables", "Fruit", "Dairy", "Snacks", "Meat/Fish", "Starches" and "Miscellaneous foods"), explaining 37.8% of the variance. Divergent validity revealed significant negative correlations between five sub-scales of the Persian-FPQ and psychological distress. The Persian version of the FPQ is a reliable and valid instrument with applicability in a broad range of the population of Persian-speaking adolescents for assessing food preferences in community-based research projects.

Abstract
Trust in one's physician drives positive health practices. However, the conceptualization and subsequent operationalization of trust have become clouded due to the multitude of approaches that have resulted in several different measures with varied dimensions and indicators. The objectives of this scoping review were: 1) to discover any new developments in the measurement of trust, 2) to identify those measures of trust, whether newly created or refined in the last ten years, that have known reliability and validity, and 3) to compare those instruments' conceptualizations, dimensions, and indicators. This researcher conducted an electronic search of three databases (PubMed, SOCAB, and PsycINFO). Two reviewers screened those selected studies and identified the following six key measurement tools, of which three had shorter, more abbreviated derivatives: the Trust in Physician Scale and its modification, the Wake Forest Physician Trust Scale and its short form, the Health Care Relationship Trust Scale and its refinement, the Trust in Oncologist Scale and its shortened form, the Trust in Health Care Providers Scale, and the Trust in My Doctor Scale. Of these six distinct tools, only the Trust in Oncologist Scale was developed and validated in non-US populations. Also identified were ten dimensions of trust: fidelity, technical competence, communicative competence, interpersonal competence (i.e., caring), honesty, confidentiality, global, behavioral, fairness, and system trust/accountability. Interpersonal competence and fairness emerged as newer dimensions that deserve further study. A comparative analysis of the indicators of these trust dimensions revealed some discrepancies that deserve theoretical and psychometric attention. In addition, incorporating item-response theory to assess measurement invariance has enhanced the assessment of external validity. This review provides a resource for researchers that will lead to a more uniform understanding of trust, thereby setting the basis for future theoretical integration and measurement development.
