Validation of the Quality Analysis of Medical Artificial Intelligence (QAMAI) tool: a new tool to assess the quality of health information provided by AI platforms.

The widespread diffusion of Artificial Intelligence (AI) platforms is revolutionizing how health-related information is disseminated, thereby highlighting the need for tools to evaluate the quality of such information. This study aimed to propose and validate the Quality Assessment of Medical Artificial Intelligence (QAMAI), a tool specifically designed to assess the quality of health information provided by AI platforms. The QAMAI tool has been developed by a panel of experts following guidelines for the development of new questionnaires. A total of 30 responses from ChatGPT4, addressing patient queries, theoretical questions, and clinical head and neck surgery scenarios were assessed by 27 reviewers from 25 academic centers worldwide. Construct validity, internal consistency, inter-rater and test-retest reliability were assessed to validate the tool. The validation was conducted on the basis of 792 assessments for the 30 responses given by ChatGPT4. The results of the exploratory factor analysis revealed a unidimensional structure of the QAMAI with a single factor comprising all the items that explained 51.1% of the variance with factor loadings ranging from 0.449 to 0.856. Overall internal consistency was high (Cronbach's alpha = 0.837). The Interclass Correlation Coefficient was 0.983 (95% CI 0.973-0.991; F (29,542) = 68.3; p < 0.001), indicating excellent reliability. Test-retest reliability analysis revealed a moderate-to-strong correlation with a Pearson's coefficient of 0.876 (95% CI 0.859-0.891; p < 0.001). The QAMAI tool demonstrated significant reliability and validity in assessing the quality of health information provided by AI platforms. Such a tool might become particularly important/useful for physicians as patients increasingly seek medical information on AI platforms.

Validity and Reliability of the Turkish Version of the Glottal Function Index

ObjectivesA comprehensive evaluation is necessary for voice-related complaints, as it can benefit both the patient and physician in busy clinical settings. This study aimed to examine the Turkish adaptation of the Glottal Function Index (GFI-T), which can be quickly administered. Study DesignsPhase 1 methodological, phase 2 prospective cohort. MethodsThis study was conducted in two phases. Firstly, the GFI was translated into Turkish, and its content validity were examined. The GFI-T was administered to 40 participants with voice disorders (M=41.3, SD=10) in the study group and 40 participants without voice disorders (M=37.5, SD=11.3) in the control group. Then GFI-T was re-administered two weeks later. The collected data were used for structural and convergent validity [correlation with Turkish version of the Voice Handicap Index-10 (VHI-10)], internal consistency, and test-retest reliability analyses. Secondly, 24 participants with vocal nodules were recruited separately from the first phase and were randomly divided into three groups. The first group underwent lax-vox therapy+vocal hygiene, the second group underwent resonance therapy+vocal hygiene, and the third group was provided only with vocal hygiene recommendations. The discriminative ability and construct validity of the GFI-T were examined by comparing pre-and post-assessments. ResultsThe results indicated that the content validity indexes were 0.98 in the experts and 0.99 in the participants. Confirmatory factor analysis of the scale confirmed that a single-factor structure and goodness-of-fit indices were suitable. The GFI-T correlated 0.92 with the Turkish version of the VHI-10. The internal consistency was 0.96, and the test-retest value was 0.99. Significant differences (p<0.001) and correlations with the Turkish version of VHI-10 were found in intragroup comparisons. ConclusionsThe GFI-T is a reliable and valid tool for the self-assessment of voice disorders. The adaptation of this study to the pediatric population is recommended.

THE RELIABILITY AND VALIDITY OF THE BALANCE MAT

BACKGROUND Reliable and accurate postural sway assessment tools are important for monitoring the postural stability of individuals so that interventions can be evaluated, and balance ability is better assessed. The Balance Mat (PSI, ACT, Australia) is a new postural sway assessment device that is relatively cheap and highly portable, but it is yet to be scientifically validated and its reliability tested. Therefore, the aims of this project were to assess the test-retest reliability and validity of the Balance Mat (BM). METHODS Seventeen participants (age range 18 – 67) were recruited, and they performed nine balance tests. The reference method for obtaining balance measurements was the AMTI AccuSway-Optimized force platform (Advanced Mechanical Technology, Inc., MA, USA), which was placed below the BM so that force plate and BM data were collected simultaneously. Each participant performed two trials for each test, which were 20 seconds in duration each. From the BM software, the sway variance, mean sway distance, sway range, sway velocity, and sway path were obtained for each trial. From the force platform, the following centre of pressure (COP) measurements were obtained: standard deviation of the radial displacement of the COP; mean radial displacement of the COP; 95% confidence ellipse area; average velocity of the COP; and COP path length. Spearman’s rank-order correlation coefficient was used to test the validity and reliability of the BM. RESULTS For the comparison between BM and force plate data, correlation coefficients ranged from 0.63 to 0.79 (p&amp;lt;0.001). For the test-retest reliability analyses, correlation coefficients ranged from 0.77 to 0.85 (p&amp;lt;0.001) among the nine tests. CONCLUSIONS The strong to very strong positive correlations suggest that the BM is a valid and reliable tool for assessing postural sway.

Turkish Adaptation, Reliability, and Validity Study of the Vaccine Acceptance Instrument

This research study aimed to assess the reliability and validity of the Turkish version of the Vaccine Acceptance Instrument (VAI). The VAI is a 20-item Likert-type scale, with responses ranging across seven points. A systematic approach was followed to translate the scale into Turkish, involving translation, expert panel evaluation, back-translation, and pilot testing. The Vaccine Acceptance Instrument and a sociodemographic data form were used for data collection. The reliability of the scale was tested by test–retest analysis, and its internal reliability was examined by Cronbach’s alpha test. The factor structure was examined using Exploratory Factor Analysis (EFA). Confirmatory Factor Analysis (CFA) was employed to assess the scale’s fit. Overall, 229 participants were included in the study. In test–retest reliability analysis, the intraclass correlation coefficient of the scale was 0.992 (95% CI: 0.987–0.996). The Cronbach’s alpha value of the scale was 0.824. A four-factor structure was determined. The model had an acceptable fit [χ2/df = 380.04/164 (2,317) p &lt; 0.001, CFI = 0.91, GFI = 0.90, AGFI = 0.906, NFI = 0.90, RMSEA = 0.076]. The mean total VAI score was 112.71 ± 17.02. The low education level of the mother, being a housewife, and parents not having the COVID-19 vaccine were statistically significantly associated with a low scale score and low vaccine acceptance (p &lt; 0.05). The Turkish adaptation of the VAI demonstrated satisfactory levels of validity and reliability following rigorous testing.

Vision-related quality of life in children: Cross-cultural adaptation and test-retest reliability of the Danish version of the paediatric refractive error profile 2.

To translate and cross-culturally adapt PREP2 into Danish and to investigate the face validity and reliability of Danish PREP2 through cognitive interviewing, Rasch and reliability analyses. The Danish PREP2 was translated using a standardized procedure and then pretested following the Three-Steps-Interviews (TSTI) process. A total of 15 myopic children aged 7-14 wearing either orthokeratology lenses (ortho-k) or single-vision spectacles (SVS) were included in pretesting comprising cognitive interviews and Rasch analysis. Data from cognitive interviewing was analysed thematically according to Collins. Rasch analysis was used to pretest the psychometric properties in terms of person- and item-fit statistics. Reliability was assessed via test-retest using Intra-class correlation coefficient (ICC) in the CONTROL study population, which consisted of 60 Danish children aged 7-14 years wearing either ortho-k or SVS. Fifteen children participated in pilot studies comprising of cognitive interviewing and Rasch analysis and 44 out of 60 CONTROL children participated in test-retest reliability analysis. The translation process resulted in a Danish version of PREP2 corroborating the original. Pretesting highlighted issues in the contextualization of items and in marking responses. Thus, we introduced a digital format with help texts. Cognitive interviewing identified issues in the following Collins' themes: comprehension (understanding of concepts), judgement (ambiguity of items) and response (selecting answers). Rasch analysis indicated that help texts were useful for clarifying context. The ICC was 0.77 (95% CI: 0.66-0.85). The cross-cultural adaptation of PREP2 was satisfactory and issues were identified and corrected through pretesting. The test-retest reliability showed substantial consistency. The instrument could be validated in a more generalizable setting in future studies. NCT03246464 (CONTROL study).

NITES, a nocturnal bladder score to aid diagnosis during the transition to older age care.

As adults transition to older age, bothersome nocturnal lower urinary tract symptoms (LUTS) become common. There is need for a reliable assessment metric to detect and measure specific symptoms. To subject the nocturnal LUTS score for older individuals, Nocturia, Incontinence, Toileting and Enuresis Symptom Score (NITES), to psychometric analysis. Factor analysis of the metric was conducted with completed questionnaires from 151 older individuals who were either admitted to a tertiary hospital or attending an outpatient continence clinic. Test re-test reliability involved 18 older community dwelling individuals attending a Geriatrician clinic completing the metric at two timepoints separated by at least 1 week. Intra-class correlation coefficients were determined for reliability of each factor and item. The NITES metric was completed by 98 hospitalized older individuals and 53 attending a continence clinic (mean age 83.2 years [SD 7.0]). Factor analysis demonstrated that one item had a floor effect and two items had poor endorsement. After test re-test reliability analysis, a further three items were removed: one due to poor correlation between timepoints and two demonstrating inadequate internal consistency. The final NITES metric is comprised of three factors: Sleep 4-items, Incontinence 4-items, and Personal Bother 2-items. A 4-item short form for symptom screening was extracted from the longer measure. The final NITES metric is a 10-item questionnaire with an embedded 4-item short symptom screen. It has utility utilized to detect nocturnal bladder symptoms in both community dwelling and hospitalized older adults.

Measuring the Reliability of a Gamified Stroop Task: Quantitative Experiment.

Few gamified cognitive tasks are subjected to rigorous examination of psychometric properties, despite their use in experimental and clinical settings. Even small manipulations to cognitive tasks require extensive research to understand their effects. This study aims to investigate how game elements can affect the reliability of scores on a Stroop task. We specifically investigated performance consistency within and across sessions. We created 2 versions of the Stroop task, with and without game elements, and then tested each task with participants at 2 time points. The gamified task used points and feedback as game elements. In this paper, we report on the reliability of the gamified Stroop task in terms of internal consistency and test-retest reliability, compared with the control task. We used a permutation approach to evaluate internal consistency. For test-retest reliability, we calculated the Pearson correlation and intraclass correlation coefficients between each time point. We also descriptively compared the reliability of scores on a trial-by-trial basis, considering the different trial types. At the first time point, the Stroop effect was reduced in the game condition, indicating an increase in performance. Participants in the game condition had faster reaction times (P=.005) and lower error rates (P=.04) than those in the basic task condition. Furthermore, the game condition led to higher measures of internal consistency at both time points for reaction times and error rates, which indicates a more consistent response pattern. For reaction time in the basic task condition, at time 1, rSpearman-Brown=0.78, 95% CI 0.64-0.89. At time 2, rSpearman-Brown=0.64, 95% CI 0.40-0.81. For reaction time, in the game condition, at time 1, rSpearman-Brown=0.83, 95% CI 0.71-0.91. At time 2, rSpearman-Brown=0.76, 95% CI 0.60-0.88. Similarly, for error rates in the basic task condition, at time 1, rSpearman-Brown=0.76, 95% CI 0.62-0.87. At time 2, rSpearman-Brown=0.74, 95% CI 0.58-0.86. For error rates in the game condition, at time 1, rSpearman-Brown=0.76, 95% CI 0.62-0.87. At time 2, rSpearman-Brown=0.74, 95% CI 0.58-0.86. Test-retest reliability analysis revealed a distinctive performance pattern depending on the trial type, which may be reflective of motivational differences between task versions. In short, especially in the incongruent trials where cognitive conflict occurs, performance in the game condition reaches peak consistency after 100 trials, whereas performance consistency drops after 50 trials for the basic version and only catches up to the game after 250 trials. Even subtle gamification can impact task performance albeit not only in terms of a direct difference in performance between conditions. People playing the game reach peak performance sooner, and their performance is more consistent within and across sessions. We advocate for a closer examination of the impact of game elements on performance.

Development and validation of the pathological lying inventory

AbstractPathological lying has been studied for over a century, but only recently validated diagnostic criteria were developed that consider the frequency, pervasiveness, and chronicity of lying, along with the distress, dysfunction, and risks of danger caused by lying. Using these new criteria, we crafted a set of survey items aimed at measuring those features. In study 1, we carried out exploratory factor analyses that confirmed a three-factor model for our resultant 19-item Pathological Lying Inventory (PLI). In study 2, we validated the PLI against several measures, demonstrating the scores on the PLI are associated with frequent, pervasive, and chronic lying, psychological distress, social dysfunction, and negative life outcomes. In study 3, we conducted a test-retest reliability analysis of the PLI over two weeks, demonstrating that the PLI has high test-retest reliability. Finally, we conducted a confirmatory factor analysis to evaluate the three-factor structure of the PLI. We believe that the PLI will offer researchers and clinicians a brief and valid tool for assessing the degree to which people exhibit patterns of pathological lying.

A new look at parenting through the cultural context: Development and initial psychometric evidence of the Interculturally Sensitive Parenting Scale (ISPAS)

This study aimed to evaluate the measurement characteristics of a newly developed scale to assess interculturally sensitive parenting for mothers and fathers of children and adolescents ranging from 4 to 18 years of age. The development of the Interculturally Sensitive Parenting Scale (ISPAS) ended up with five separate samples, with a total of 1522 parents (884 mothers and 638 fathers), in a five-step process. In the first phase, we generated a pool with 28 items and received input from content experts (n = 5) and cognitive interviews (n = 10), resulting in 23 items. In Study 2 (n = 602), which included inter-item and item-total correlations, eigenvalues, exploratory factor analysis, scree plots, and parallel analysis, six more items were excluded from the item pool, resulting in a one-dimensional construct with 17 items. In Study 3 (n = 607), along with parenting role (mother and father) invariance, confirmatory factor analysis supported the single-factor construct with 17 items, with excellent internal consistency with a high Cronbach's alpha. In Study 4 (n = 303), the analyses indicated that the ISPAS with a one-dimensional construct had good discriminant and convergent validity. Lastly, the 4-week test-retest reliability analysis of the ISPAS in Study 5 (n = 204) supported the stability of the measure. Taken together, the findings validated the usage of the 17-item ISPAS in reliably assessing mothers' and fathers' interculturally sensitive parenting. We hope academics from different disciplines, practitioners, mental health professionals, and educators will benefit from the assessment of the ISPAS presented in this study.

Development and Evaluation of a New Self-Administered Near Visual Acuity Chart: Accuracy and Feasibility of Usage.

Background: Visual acuity (VA) assessments are crucial in ophthalmology but traditionally rely on in-clinic evaluations. The emergence of telemedicine has spurred interest in creating dependable self-administered VA tests for use beyond standard clinical environments. This study evaluated the practicality and validity of a self-administered near VA card test against traditional Snellen and Rosenbaum Pocket Vision Screener (RPVS) methods for home monitoring and enhancing clinical workflow. Methods: In a cross-sectional study, a near VA card (Hadassah Self-Visual Acuity Screener (HSVA)) was developed with written and videotaped instructions for self-use. Patients with a minimal best-corrected VA (BCVA) of 1.0 LogMAR in at least one eye were recruited from ophthalmology and optometry clinics. Outcomes included the mean BCVA difference between the self-administered values and those obtained by the examiner, and correlations between BCVA values obtained by the Snellen, RPVS, HSVA, and previous distance BCVA methods according to the patients' electronic medical records. Results: A total of 275 participants (mean age: 42.5 ± 19.4 years; range: 18-89 years; 47% female) were included. Test-retest reliability analysis of the HSVA demonstrated a very good correlation and repeatability (n = 38 patients; Rs = 1.0; p < 0.001). Accuracy analysis revealed the mean LogMAR BCVA values of an additional 237 patients obtained by the Snellen, RPVS, and HSVA methods were similar (p = 0.10). The self-test BCVA results obtained by the HSVA agreed with the masked examiner-tested VA results (n = 67 patients; p = 0.17; Rs = 0.87; ICC = 0.96). Similar results were obtained when stratification by median age (42 years) was performed. Bland-Altman analysis of the HSVA and RPVS methods demonstrated a good agreement. To assess whether the HSVA could predict the VA results in the clinically used charts, multivariate analysis was used and revealed that the HSVA predicted the RPVS results (β = 0.91; p = 0.001; R2 = 0.88), and the self-test HSVA predicted the Snellen VA results within two lines (β = 0.93; p = 0.01; R2 = 0.36). Conclusions: The home-based HSVA assessment exhibited high test-retest reliability, accuracy, and alignment with clinical-standard VA tests. Its efficacy in self-testing mirrored examiner-conducted VA assessments and accurately predicted Snellen VA outcomes, indicating the HSVA's suitability for self-monitoring in chronic ocular conditions or when access to conventional examinations is limited. The utility of self-administered VA tests may extend beyond ophthalmology and optometry, potentially benefiting primary care, emergency medicine, and neurology. Further research is needed to explore and validate the practical applications of remote VA testing.

Reliability and validity estimation of Urdu version of Children Emotion Management Scales (CEMS) in Pakistan.

The present study aimed to translate and validate Children's Emotion Management Scales into Urdu, the national language of Pakistan. The current study comprised three different phases, i.e., phase I: Cross-language validation over a sample of (N = 169) school children, estimated at a 1-week interval. The results indicate a significant correlation (r = 0.846-0.891) at p < 0.01. In phase II, the internal consistency reliability (r = 0.808-0.904) and split-half reliability (r = 0.737-0.898) of the scale were assessed (N = 683) at p < 0.01. Furthermore, significant results for test-retest reliability analysis (N = 168) were obtained (r = 0.736-0.917 at p < 0.01), following the confirmatory factor analysis (CFA) (N = 1,083). Exploratory factor analysis (EFA) was conducted on the same sample chosen for CFA. EFA resulted in the retention of original inhibition (INH), dysregulated expression (DYS), and emotional coping (EMO) factors. CFA findings suggest a good model fit. In phase III, convergent validity and divergent validity were checked (N = 385, 255, and 213). Convergent validity of INH and DYS subscales and divergent validity of EMO subscales were established, with SBI (r = 0.217-0.609; 0.210-0.445; -0.026 to -0.553), SHS (r = 0.417-0.441; 0.480-0.546; -0.338 to -0.582), and suppression subscale of ERQ (r = 0.430-0.480; 0.468-0.522; -0.245 to -0.369) at p < 0.01. For divergent validity of INH and DYS subscales and convergent validity of EMO subscales, their scores were correlated with the SPS (r = -0.204 to -0.350; -0.318 to -0.459; 0.191-0.531), RSE Scale (r = -0.226 to -0.351; -0.279 to -0.352; 0.255-0.507), DTS (-0.290 to -0.617; -0.369 to -0.456; 0.246-0.680), and reappraisal subscale of ERQ (r = -0.456 to -0.541; -0.329 to -0.544; 0.446-0.601) at p < 0.01. It is concluded that the scale is reliable and valid with sound psychometric properties.

[Spanish version of the Nordic Musculoskeletal Questionnaire: cross-cultural adaptation and validation in nursing aides].

The aim of this study is to translate, culturally adapt, and validate a Spanish version of the Nordic Musculoskeletal Questionnaire for a sample of nursing assistant aides. The questionnaire was translated and culturally adapted. Next, it was included in a battery of tests that was completed by 526 nursing assistants working in residential care homes in the Principality of Asturias (Spain). To assess its validity, the Exploratory Factor Analysis and the Confirmatory Factor Analysis were used. The internal consistency was estimated with McDonald's Omega coefficient (?), complemented by the test-retest reliability analysis through the intraclass correlation coefficient. The validity of the criteria was established by the correlation between total score on the test and quality of life measures, job insecurity and psychological demand, and social support at work. The Exploratory Factor Analysis and Confirmatory Factor Analysis adjustment indices confirmed it is a unidimensional test. The internal consistency values indicated very high reliability (? = 0.81). Similarly, the intraclass correlation coefficient showed statistically significant values and an excellent correlation coefficient (r = 0.95). The validity of the criteria showed a statistically significant correlation with all the constructs studied, particularly with quality of life. This Spanish version of the Nordic Musculoskeletal Questionnaire has good psychometric qualities for a population of nursing aides and therefore may be a valid and reliable tool for assessing musculoskeletal disorders.

Development and validation of fall risk perception scale for patients with Parkinson's disease.

Perception assessment plays an important role in fall risk awareness and fall prevention. Parkinson's disease patients with motor dysfunction are at high risk of falling. Currently, no instrument has been explicitly crafted to assess the risk perception of fall in PD patients. The purpose of this study was to develop and validate the fall risk perception scale for PD patients (FRPS-PD), providing healthcare professionals with a effective assessment tool to enhance proactive fall prevention initiatives. Based on the Proactive Health theory and Risk Perception Attitude (RPA) Framework, the questionnaire was developed through literature review, semi-structure interview, expert consultation and pilot testing. A total of 428 patients with PD from Grade A tertiary hospitals in Shanghai, Hangzhou and Anhui from January 2023 to July 2023 were recruited. The items and dimensions in the scale were explored and confirmed using item-analysis, content validity, exploratory factor analytical (EFA), confirmatory factor analytical (CFA), internal consistency and test-retest reliability analysis. A total of 16-items, 2-dimensions structure were identified, including 12 items of risk perception and 4 items of self-efficacy dimension. The cumulative variance of EFA model was 73.669%, further CFA showed that acceptable model fit (χ2/df = 2.226, RMSEA = 0.074, NF = 0.928, TLI = 0.951, CFI = 0.959, GFI = 0.887 and AGFI = 0.848). The content validity index was 0.956. The reliability of the scale was 0.952 using Cronbach's α coefficient method. The test-retest reliability was 0.944. The FRPS-PD is a valid and reliable measurement for evaluating fall risk perception level for individuals with PD in mainland China.

Digital Gait Measures Capture 1-Year Progression in Early-Stage Spinocerebellar Ataxia Type 2.

With disease-modifying drugs in reach for cerebellar ataxias, fine-grained digital health measures are highly warranted to complement clinical and patient-reported outcome measures in upcoming treatment trials and treatment monitoring. These measures need to demonstrate sensitivity to capture change, in particular in the early stages of the disease. Our aim is to unravel gait measures sensitive to longitudinal change in the-particularly trial-relevant-early stage of spinocerebellar ataxia type 2 (SCA2). We performed a multicenter longitudinal study with combined cross-sectional and 1-year interval longitudinal analysis in early-stage SCA2 participants (n = 23, including nine pre-ataxic expansion carriers; median, ATXN2 CAG repeat expansion 38 ± 2; median, Scale for the Assessment and Rating of Ataxia [SARA] score 4.8 ± 4.3). Gait was assessed using three wearable motion sensors during a 2-minute walk, with analyses focused on gait measures of spatio-temporal variability that have shown sensitivity to ataxia severity (eg, lateral step deviation). We found significant changes for gait measures between baseline and 1-year follow-up with large effect sizes (lateral step deviation P = 0.0001, effect size rprb  = 0.78), whereas the SARA score showed no change (P = 0.67). Sample size estimation indicates a required cohort size of n = 43 to detect a 50% reduction in natural progression. Test-retest reliability and minimal detectable change analysis confirm the accuracy of detecting 50% of the identified 1-year change. Gait measures assessed by wearable sensors can capture natural progression in early-stage SCA2 within just 1 year-in contrast to a clinical ataxia outcome. Lateral step deviation represents a promising outcome measure for upcoming multicenter interventional trials, particularly in the early stages of cerebellar ataxia. © 2024 The Authors.

The Italian version of the 16-item Prodromal Questionnaire (PQ-16) and its psychometric features in help-seeking ultra-high-risk subjects and in the general population.

Increasing attention to the early stages of psychosis and the identification of symptomatic prodromal states have led to the development of a growing number of screening tools. The 16-item version of the Prodromal Questionnaire (PQ-16) is a worldwide used self-administered tool for this purpose. However, to date, fundamental psychometric properties of PQ-16 were not thoroughly investigated. This study aimed to examine the structural validity, measurement invariance, reliability and other psychometrical properties of the Italian version of the PQ-16 (iPQ-16) in help-seeking individuals and in the general population. The iPQ-16 was administered to 449 young outpatients attending six community mental health services and to 318 control participants enrolled in educational environment. Confirmatory factor analyses (CFAs), measurement invariance (MI) between the help-seeking group and the general population sample, convergent validity, test-retest reliability, internal consistency, and prevalence analyses were performed. Lastly, the validity of the adopted PQ-16 cut-offs through Receiver Operating Characteristic (ROC) curves plotted against CAARMS diagnoses was also tested. CFAs confirmed the single-factor structure for the iPQ-16 and scalar MI was reached. The iPQ-16 showed high internal consistency, test-retest reliability, convergent validity, and acceptable diagnostic accuracy. ROC analysis suggested a score of ≥4 as best cut-off. The iPQ-16 represents a valid and reliable questionnaire for the assessment of high mental risk in both Italian outpatients and general student population. It has good psychometric properties and is easy to implement as UHR screening for clinical as well as research purposes.

Validity and Reliability Study of Online Cognitive Tracking Software (BEYNEX).

Detecting cognitive impairment such as Alzheimer's disease early and tracking it over time is essential for individuals at risk of cognitive decline. This research aimed to validate the Beynex app's gamified assessment tests and the Beynex Performance Index (BPI) score, which monitor cognitive performance across seven categories, considering age and education data. Beynex test cut-off scores of participants (n = 91) were derived from the optimization function and compared to the Montreal Cognitive Assessment (MoCA) test. Validation and reliability analyses were carried out with data collected from an additional 214 participants. Beynex categorization scores showed a moderate agreement with MoCA ratings (weighted Cohen's Kappa = 0.48; 95% CI: 0.38-0.60). Calculated Cronbach's Alpha indicates good internal consistency. Test-retest reliability analysis using a linear regression line fitted to results yielded R∧2 of 0.65 with a 95% CI: 0.58, 0.71. Beynex's ability to reliably detect and track cognitive impairment could significantly impact public health, early intervention strategies and improve patient outcomes.

Development and validation of nursing students' moral sensitivity questionnaire in Taiwan.

Ethical literacy is a critical aspect of professional nursing development. It is considered an essential quality that nursing professionals should possess throughout their careers. Moral sensitivity serves as the foundation for developing ethical literacy. The objective of this study was to develop a reliable tool for assessing moral sensitivity among nursing students. The questionnaire was developed following a rigorous approach, consisting of three stages process, combining the Schwartz-Barcott and Kim hybrid model of concept development with the methodology suggested by Devellis and Waltz. A total of 297 nursing students (287 females, 10 males; mean age: 18.7 years) participated in the study, with five invalid questionnaires excluded from the analysis. The questionnaire's reliability was established through internal consistency and test-retest reliability analyses. Furthermore, the moral sensitivity questionnaire for nursing students demonstrated satisfactory validity through the results of construct, convergent and discriminant validation procedures. The study findings revealed a significant correlation between the internship performance of students and their overall moral sensitivity score. The questionnaire would be appropriated to be included as a supplemental measure for ethical literacy evaluation.

The Psychometric Properties of the Arabic Version of the Anxiety and Preoccupation About Sleep Questionnaire (APSQ).

Insomnia disorder is a common health condition; it has a role in increasing the possibility of developing other psychological disorders, including anxiety and depression. Anxiety and preoccupation with sleep are two examples of common cognitive factors that contribute to the development of chronic insomnia; thus, it is important to have a tool that assesses worry in insomnia. There is no comprehensive psychiatric measure to assess anxiety and preoccupation with sleep in Arabic. We conducted this study to translate, adapt, and validate the Arabic version of the Anxiety and Preoccupation about Sleep Questionnaire (APSQ), providing a reliable psychometric tool to assess concerns regarding sleep within Arabic-speaking communities. The translation process of the scale involved several steps, including forward and backward translation. A cross-sectional study was conducted using an online survey completed by 523 participants from various Arabic-speaking countries. Psychometric analysis was performed utilizing the R software, including internal consistency, test-retest reliability, and confirmatory factor analysis. In addition, convergent and divergent against the Athens insomnia scale (AIS) and general anxiety disorder (GAD) were conducted. The Arabic-translated form of the APSQ expresses excellent internal consistency with a value of 0.91 for both Cronbach's α and McDonald's ω. The test-retest reliability of a subsample showed an excellent coefficient of 0.93 (p<0.01). A good fit of the APSQ was observed by CFI = 0.93, TLI = 0.91, SRMR = 0.05, and RMSEA = 0.1. Convergent and divergent against AIS and GAD showed statistically significant correlations of 0.85 (p<0.01) and 0.69 (p<0.01), respectively. Our sample showed a mean APSQ score of 31.28 ± 8.31, and the mean age was 23.62 ± 7.5. The Arabic APSQ is reliable and valid for measuring anxiety and preoccupation with sleep in Arabic countries. Using translated APSQ for clinical diagnosis and research is currently trustworthy.

Digital Life Balance Scale: Validity and Reliability in the Turkish Context

In our increasingly interconnected world, maintaining a healthy balance between online and offline activities is crucial for personal well-being. The Digital Life Balance (DLB) Scale has been introduced to understand the impact of Internet use on well-being, drawing upon the framework of the psychology of harmony and harmonization. This study is aimed at validating and assessing the reliability of the DLB Scale among Turkish university students. A sample of 424 university students (50.7% females, 49.3% males; age range: 20-31 years) participated. The scale was translated into Turkish, and its language validity was ensured through expert reviews. Confirmatory factor analysis supported the construct validity of the scale, effectively measuring Digital Life Balance in the Turkish context. Convergent validity analysis revealed significant correlations between the DLB Scale and measures of well-being and addiction tendencies. The DLB Scale exhibited good internal consistency (Cronbach’s alpha and composite reliability). Test-retest reliability analysis showed consistent responses over a three-week interval. These findings provide empirical evidence for the validity and reliability of the scale, making it a valuable tool for assessing individuals’ perceptions of balance in their online and offline activities.

Cross-Cultural Adaptation and Psychometric Properties of the Chinese Version of the Knee Osteoarthritis Fears and Beliefs Questionnaire

This study aimed to adapt and validate the Knee Osteoarthritis Fears and Beliefs Questionnaire (KOFBeQ) for Chinese patients, thereby advancing the understanding of fear-avoidance behaviors. Adopting a cross-sectional design, data were collected for 241 subjects (78.8% women; mean age 68.0 ± 7.8 years) across various healthcare settings in Hong Kong. Exploratory factor analysis resulted in an 11-item questionnaire with three distinct subscales, covering fears and beliefs related to physicians and disease (six items), daily living activities (three items), and sports and leisure activities (two items). The overall Cronbach’s α coefficient was 0.86, indicating strong internal consistency. The questionnaire exhibited favorable convergent validity. Confirmatory factor analyses confirmed a good model fit. Test–retest reliability analysis indicated a high intraclass correlation coefficient of 0.93 (95% confidence interval: 0.88, 0.96), and a Bland–Altman plot revealed a slight bias in two measurements (0.97 [0.19]) without a systematic trend. The adapted Chinese version of the KOFBeQ demonstrated robust psychometric properties in terms of validity and reliability, providing an effective tool for surveying Chinese patients with knee osteoarthritis. These findings offer valuable insights for clinicians and patients, aiding in informed decision-making and improved rehabilitation strategies.
