Cross-cultural adaptation, reliability, and validity of the Persian version of the overactive bladder questionnaire (OAB-V8).

Background and objectives: Overactive bladder (OAB) is characterized by urinary frequency and is recognized as a disorder. Various tools are available for diagnosing this condition. This study aimed to evaluate the reliability and validity of the Persian version of the 8-item Overactive Bladder Scale (OAB-V8). Methods: This analytical cross-sectional study was conducted on a sample of 150 OAB patients. The OAB-V8 scale was translated and culturally adapted following established guidelines. Face and content validity were assessed using the Impact Score (IS), Content Validity Index (CVI), and Content Validity Ratio (CVR) indices. Reliability was evaluated by calculating Cronbach's alpha (α) and utilizing the test-retest method (Intra-class correlation coefficients (ICC)). Construct validity was explored through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). All statistical analyses were carried out using SPSS version 24 and AMOS version 24, with a significance level set at 5 %. Results: The face validity was confirmed, with all items having an IS value greater than 1.5. Content validity was also confirmed, as most items had a Content Validity Index (CVI) higher than 0.79, and the average Content Validity Ratio (CVR) value was 0.96. In the initial phase of Exploratory Factor Analysis (EFA), the sample adequacy and suitability of the exploratory analysis were confirmed (Kaiser-Meyer-Olkin (KMO) test value = 0.784, Bartlett's Test p-value <0.05). Two dimensions explaining 61.87 % of the variance were then extracted. In the Confirmatory Factor Analysis (CFA), the fit indices were deemed acceptable (χ^2/df = 2.006, CFI = 0.96, GFI = 0.95, AGFI = 0.89, TLI = 0.93, RMSEA = 0.08). The reliability was confirmed with an alpha coefficient of 0.81 and an Intraclass Correlation Coefficient (ICC) of 0.98. Conclusion: The Persian version of the OAB-V8 questionnaire demonstrated good validity and reliability, indicating its suitability for use in Persian-speaking countries.

Validity and reliability of the Turkish version of the Australian National University-Alzheimer's Disease Risk Index (ANU-ADRI).

INTRODUCTION: There is still a requirement for concise, practical scales that can be readily incorporated into everyday schedules and predict the likelihood of dementia onset in individuals without dementia. This study aimed to assess the reliability of the ANU-ADRI (Australian National University Alzheimer's Disease Risk Index)-Short Form in Turkish geriatric patients. METHODS: This methodological study involved 339 elderly patients attending the geriatric outpatient clinic for various reasons. The known-group validity and divergent validity were assessed. The ANU-ADRI was administered during the baseline test and again within one week for retest purposes. Alongside the ANU-ADRI, all participants underwent a comprehensive geriatric assessment, including Activities of Daily Living (ADL), mobility assessment (Performance-Oriented Mobility Assessment (POMA) and Timed Up and Go Test), nutritional assessment (Mini Nutritional Assessment (MNA)), and global cognition evaluation (Mini-Mental State Examination (MMSE)). RESULTS: The scale demonstrated satisfactory linguistic validity. A correlation was observed between the mean scores of the ANU-ADRI test and retest (r = 0.997, p < 0.001). Additionally, there existed a moderate negative linear association between the ANU-ADRI and MMSE scores (r = -0.310, p < 0.001), POMA (r = -0.406, p < 0.001), Basic ADL (r = -0.359, p < 0.001), and Instrumental ADL (r = -0.294, p < 0.001). Moreover, a moderate positive linear association was found between the ANU-ADRI and the Timed Up and Go Test duration (r = 0.538, p < 0.001). CONCLUSION: The ANU-ADRI-Short Form was proved as a valuable tool for clinical practice, facilitating the assessment of Alzheimer's disease risk within the Turkish geriatric population.

Psychometric evaluation of the Chinese version of alcohol relapse risk scale (C-ARRS) in patients with alcohol use disorder.

Alcohol use disorder (AUD) is recognized as a chronic relapsing disorder. Alcohol Relapse Risk Scale (ARRS), a multidimensionally self-rating scale, was developed initially by the Japanese to assess the risk of alcohol reuse. The study aimed to validate the reliability and factor structure of the Chinese version of the ARRS (C-ARRS) for patients with AUD. A total of 218 patients diagnosed with AUD according to DSM-5 were recruited for self-administering C-ARRS. We assessed the internal consistency of C-ARRS using Cronbach's α coefficients and examined the factor structure through confirmatory factor analysis (CFA). Additionally, we investigated the concurrent validity by correlating C-ARRS with the Visual Analog Scale of Alcohol Craving (VAS), Penn Alcohol Craving Score (PACS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) scores. CFA demonstrated inadequate data fit for the original 32-item C-ARRS, prompting the development of a revised 27-item version consisting of 6 subscales with satisfactory model fit estimates. The 27-item C-ARRS exhibited favorable internal consistency, with Cronbach's α ranging from 0.611 to 0.798, along with adequate factor loadings. The 27-item C-ARRS scores displayed significant correlations with the scores of VAS, PACS, BDI and BAI (p < .001). Our results indicated favorable reliability and factor structure of the 27-item C-ARRS. The significant correlation between the 27-item C-ARRS and clinical measures (such as depression, anxiety, and craving) demonstrates satisfactory concurrent validity. These observations collectively support the feasibility of using 27-item C-ARRS to assess the risk of alcohol relapse in patients with AUD.

Estimating intracluster correlation for ordinal data.

In this paper, we consider the estimation of intracluster correlation for ordinal data. We focus on pure-tone audiometry hearing threshold data, where thresholds are measured in 5 decibel increments. We estimate the intracluster correlation for tests from iPhone-based hearing assessment applications as a measure of test/retest reliability. We present a method to estimate the intracluster correlation using mixed effects cumulative logistic and probit models, which assume the outcome data are ordinal. This contrasts with using a mixed effects linear model which assumes that the outcome data are continuous. In simulation studies, we show that using a mixed effects linear model to estimate the intracluster correlation for ordinal data results in a negative finite sample bias, while using mixed effects cumulative logistic or probit models reduces this bias. The estimated intracluster correlation for the iPhone-based hearing assessment application is higher when using the mixed effects cumulative logistic and probit models compared to using a mixed effects linear model. When data are ordinal, using mixed effects cumulative logistic or probit models reduces the bias of intracluster correlation estimates relative to using a mixed effects linear model.

Gameful Experience Scale: Reliability and Validity in Nursing Students.

Objective: Nursing students are among the groups where gamification applications are used effectively and frequently in educational technologies. This study aimed to adapt the Gameful Experience Scale (GAMEX) to the Turkish language and test its validity and reliability. Materials and Methods: The study was conducted with 620 nursing students studying an undergraduate nursing program between March and May, 2023. Data were collected using a personal information form and GAMEX-Turkish Form. Results: The validity and reliability of the five-factor structure scale with 27 items were confirmed. In confirmatory factor analysis, all factor loads were found to be >0.56. The fit indexes of the scale were χ2/df = 2.8, goodnessof-fit index = 0.90, comparative fit index = 0.94, and root mean square error of approximation = 0.55. Cronbach's alpha coefficient of the overall scale was 0.89. Conclusion: As a result of this study, the Turkish version of GAMEX was found to be a valid and reliable tool that can be used to evaluate the game experience in nursing students' training.

Reliability and validity tests of the Chinese version of the Geriatric Locomotive Function Scale (GLFS-25) in tumor survivors.

Objective: To evaluate the reliability and validity of the Chinese-translated Geriatric Locomotive Function Scale (GLFS-25) for the assessment of locomotive syndrome (LS) in individuals surviving malignancies. Methods: 393 tumor survivors at a general hospital in China were recruited. The Chinese version of GLFS-25 was utilized to conduct a cross-sectional survey to ascertain the tool's efficacy in measuring LS in this cohort. The scale's validity was examined through content, structural and discriminant validity assessments, while its reliability was investigated by determining the internal consistency (via Cronbach's α coefficient) and test-retest reliability (via intragroup correlation coefficient, ICC). Results: The Chinese-adapted GLFS-25 demonstrated a robust scale-level content validity index of 0.94, while item-level content validity indices ranged from 0.83 to 1.00 across individual items. The suitability of the scale for structural validity assessment was confirmed via exploratory factor analysis, yielding a Kaiser-Meyer-Olkin measure of 0.930 and a significant Bartlett's test of sphericity (χ2 = 3217.714, df = 300, P < 0.001). Subsequent confirmatory factor analysis (CFA) extracted four distinct factors: Social Activity Engagement, Daily Living Ability, Pain Experience and Physical Mobility. These factors accounted for 72.668 % of the variance, indicating substantial construct validity for measuring LS among this population. CFA supported the model's fit with the following indices: χ2/df = 1.559, RMSEA = 0.077, GFI = 0.924, CFI = 0.941, NFI = 0.919, and TLI = 0.933. The factor loadings for the four factors ranged from 0.771 to 0.931, indicating the items corresponding to the four factors effectively represented the constructs they were designed to measure. The correlation coefficients among the four factors were between 0.306 and 0.469, all lower than the square roots of the respective AVEs (0.838-0.867). This suggests a moderate correlation among the four factors and a distinct differentiation between them, indicating the Chinese version of the GLFS-25 exhibits strong discriminant validity in Chinese tumor survivors. Reliability testing revealed a high Cronbach's α coefficient for the overall scale at 0.961, with the subscales yielding coefficients of 0.751, 0.836, 0.930, and 0.952. The overall ICC was determined to be 0.935, with subscale ICCs ranging from 0.857 to 0.941, reinforcing the scale's reliability in this context. Conclusions: The Chinese version of the GLFS-25 exhibits strong reliability and validity for the assessment of LS in tumor survivors. It may serve as a diagnostic tool for LS, contributing to the prevention and management of musculoskeletal disorders and enhancing the prognosis for this patient population.

Is a portable pressure plate an alternative to force plates for measuring postural stability and interlimb coordination of quiet standing balance control?

Introduction: Center-of-pressure (COP) synchronization and symmetry can inform adaptations in balance control following one-sided sensorimotor impairments (e.g., stroke). As established force plates are impossible to transport, we aimed to criterion validate a portable pressure plate for obtaining reliable COP synchronization and symmetry measures, next to conventional postural stability measures. Methods: Twenty healthy adults participated. In a single session, three 40-s eyes-open and eyes-closed quiet stance trials were performed per plate-type, randomly ordered. Individual-limb COPs were measured to calculate between-limb synchronization (BLS) and dynamic control asymmetry (DCA). Net COP (i.e., limbs combined) area, amplitude, and velocity were used to describe anteroposterior (AP) and mediolateral (ML) postural stability. Criterion validity was evaluated using Spearman correlations (r) and Bland-Altman plots. Test-retest reliability was tested using intraclass correlation coefficients (ICC). Results: Strong correlations (r > 0.75) and acceptable reliability (ICC > 0.80) were found regarding individual-limb COP velocity and DCA, net COP ML amplitude and AP and ML velocities. Bland-Altman plots yielded possible proportional bias; the pressure plate systematically underestimated COP scores by force plates and a larger error associated with a larger measurement. Conclusions: Despite correlations between instruments and sufficient reliability for measuring postural stability and DCA, this technical note strongly suggests, due to a systematic deviation, using the same plate-type to accurately assess performance change within subjects longitudinally over time.

Developing and Validating the Preschool Nutrition Education Practices Survey.

OBJECTIVE: Validate the Preschool Nutrition Education Practices Survey. DESIGN: Iterative approach combining design-based research and Standards for Educational and Psychological Testing. SETTING: Los Angeles, CA and Philadelphia, PA Early Care and Education (ECE) classrooms. PARTICIPANTS: Expert panel members (n = 7); ECE teachers: interviews (n = 8), pilot survey (n = 31), and final survey (n = 136). VARIABLES MEASURED: Early care and education nutrition education practices used in the classroom either during class time or mealtime. ANALYSIS: Qualitative content analysis was implemented for content, response process, and consequences of testing validity evidence. Rasch rating scale analysis was conducted for the response process and internal structure validity and reliability evidence. RESULTS: Qualitative field-testing produced strong content, response process, and consequences of testing validity evidence to inform survey modifications. Quantitative field-testing generated a psychometrically sound, well-targeted 12-item survey on a 4-point frequency scale with excellent item and person reliability (0.97 and 0.93 respectively) and separation (5.36 and 3.77 respectively); good Rasch Principal Components Analysis findings (60.3%); and productive item fit statistics (0.50-1.50 logits). CONCLUSIONS AND IMPLICATIONS: Robust validity (content, response process, consequences of testing, internal structure) and reliability evidence were demonstrated for using the Preschool Nutrition Education Practices Survey to assess ECE teachers' use of nutrition education practices. Future research is needed to examine its relationship to other variables, such as nutrition teaching efficacy, and to determine its ability to detect change in ECE nutrition education practices over time and across groups.

Turkish translation and transcultural validity and reliability of an assessment tool for spasticity: Leg Activity Measure (Leg A).

BACKGROUND: The Leg Activity Measure is the only self-report measure that has been published to date that takes into account both the influence on quality of life and passive and active function in the literature. AIMS: The purpose is to examine the translation, cross-cultural adaptation validity and reliability of the Turkish version of the Leg Activity Measure (Tr-LegA). METHODS: Neurological patients (n = 52) with lower limb spasticity (aged 47.09 ± 14.74 years) were enrolled. The study consisted of two stages. At the first stage, the scale was translated into Turkish and culturally adapted. Validity and reliability analyses were conducted at the second stage. Construct validity was evaluated by exploratory factor analysis (EFA). The Rivermead Mobility Index (RMI), Nottingham Health Profile (NHP), and Functional Independence Measure (FIM) were used for convergent validity. The reproducibility (test-retest reliability) was assessed by the intraclass correlation coefficient (ICC). Furthermore, the standard error of measurement (SEM) was calculated. RESULTS: EFA suggested one factor for the Passive Function and two factors for the Active Function and Impact on Quality of Life Scales (QoL). Tr-LegA Passive and Active Function Scales were correlated with the total RMI, NHP, and FIM (p < 0.05). Tr-LegA Impact on Quality of Life Scale was correlated with the RMI and NHP (p < 0.05). Tr-LegA Passive Function Scale (ICC = 0.997), Tr-LegA Active Function Scale (ICC = 0.996), and Tr-LegA Impact on Quality of Life Scale (ICC = 0.976) had good reliability. Only Passive Function Scale had a significant floor effect (25%). CONCLUSIONS: Tr-LegA is a valid and reliable multidimensional scale for passive and active function and quality of life in patients with lower limb spasticity. THE CLINICAL TRIAL NUMBER: NCT05182411.

The kmo sampling appropriateness of the scale is 0.800. The load of six dimensions in the total amount table is between 0.58 and 0.73. The fitting coefficient of each item of the structural model is between 0.45-0.73, and the correlation between each dimension and the total table is between 0.24-0.52. Scale cronbach's α The coefficient was 0.83 and the test-retest reliability was 0.90. The content validity of the scale ranged from 0.554 to 0.775. The scale has good reliability and validity, and can be used to evaluate undergraduate students' educational psychology.

Examining the Performance of the Sexual Minority Adolescent Stress Inventory with Transgender and Gender-Diverse Youth and Sexual Minority Emerging Adults: A Methodological Study.

Purpose: We examined the psychometric properties and criterion validity of the Sexual Minority Adolescent Stress Inventory (SMASI) among 730 sexual minority (SM) and transgender and gender-diverse (TGD) youth aged 14 to 24 years who participated in a human immunodeficiency virus study. Methods: We tested the factor structure of the global scale and subscales and measurement invariance across age, gender identity, sex assigned at birth, sexual identity, ethnoracial identity, and city. For criterion validity, we regressed mental health and substance use measures on the global scale. Results: The global scale had excellent fit (comparative fit index = 0.95) and high reliability (omega = 0.89). Subscale model fit was adequate. We confirmed invariance by gender identity and age and established criterion validity. Conclusion: The SMASI exhibits strong psychometric properties among SM emerging adults and TGD youth. Modifications could enhance the SMASI to better capture both sexual and gender minority stress among ethnoracial minority youth.

The Validity and Reliability of a Smartphone Application for Measuring Wrist and Metacarpophalangeal Joint Motion.

Background Accurate measurement of the range of motion (ROM) is crucial for guiding upper extremity rehabilitation. Inaccurate measurements can mislead clinicians and harm patient compliance. This study aimed to evaluate the validity and reliability of a smartphone application (Angulus) for measuring wrist and metacarpophalangeal (MCP) joint ROM. Methodology This study included 64 volunteers with no prior wrist injuries. The wrist flexion/extension, radial/ulnar deviation, and MCP joint flexion/extension ROM were assessed by an experienced physiotherapist (Assessor 1) using the Angulus and a standard two-arm goniometer. The validity of Angulus was evaluated by correlating it with the goniometer measurements using the Pearson correlation coefficient. For the reliability analysis, an inexperienced biomedical engineer (Assessor 2) performed the same measurements using Angulus twice in different sessions, in addition to Assessor 1. The intra-rater and inter-rater reliability were tested using the intraclass correlation coefficient. Results The mean age of the participants was 29.5 ± 8.2 years, with 62% being female. The validity of the Angulus app measurements was indicated by the adequate to excellent correlation between the Angulus and goniometer measurements (ranging from 0.44 to 0.81). The intra-rater reliability of the Angulus app was excellent for Assessor 1 (ranging from 0.76 to 0.90) and adequate to excellent for Assessor 2 (ranging from 0.71 to 0.88). The inter-rater reliability of Angulus was excellent (ranging from 0.91 to 0.96). Conclusions Angulus is a valid and reliable method to measure the wrist and MCP joint ROM.

Development and Validation of the Resilience Scale for Kidney Transplantation (RS-KTPL).

PURPOSE: This study developed a resilience scale for kidney transplantation (RS-KTPL) and assessed its reliability and validity. METHODS: During the tool development phase, the concept of resilience in 10 patients who had undergone a kidney transplant was analyzed by integrating results from the theoretical and field research stages. Initial tool items were then derived. These items underwent content validity verification, item review, and a preliminary survey. The validation phase involved two main surveys, conducted using the preliminary 59 items derived from the development phase for data gathering. The first survey had 266 participants, and the second had 205 participants. Using the collected data, the structural validity, convergent validity, discriminant validity, criterion validity, and reliability of the tool items were verified, ultimately establishing the final items. RESULTS: The RS-KTPL comprises six factors with 27 items confirmed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) on a 4-point Likert scale: positive thought transition through recovery belief, supportive relationships with others, self-awareness of negative psychological reactions, physical health control, homeostasis control, and supportive relationships with medical staff. The cumulative explanation of the tool was 50.71%. The model fit of the RS-KTPL was represented as follows: GFI 0.88, CFI 0.93, TLI 0.91, RMSEA 0.04, and SRMRI 0.06. Convergent, discriminant, and criterion validity were also secured. The reliability of the tool, measured by Cronbach α was 0.87. CONCLUSIONS: The RS-KTPL can be used to identify the level of resilience in patients who have undergone a kidney transplant, enabling them to recognize their strengths and areas of improvement for enhanced resilience. This tool can be applied in clinical nursing practices to comprehensively assess the resilience of patients with a kidney transplant, providing direction for nursing intervention plans to enhance patient resilience.

Validity of the Korean Version of the Brief Irritability Test in Psychiatric Patients.

OBJECTIVE: This study aimed to investigate the validity and reliability of the Korean version of the Brief Irritability Test (BITe) and adapt it for Korean patients with psychiatric disorders. METHODS: A total of 296 patients at the Department of Psychiatry of Hanyang University Guri Hospital completed the BITe, Korean Beck Depression Inventory-II, Korean Beck Anxiety Inventory, the Korean version of the State-Trait Anger Expression Inventory, and Barratt Impulsiveness Scale-11. Construct validity was confirmed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Reliability testing included assessments of internal consistency (Cronbach's α) and item-total correlations. Convergent validity was examined through correlational analyses with variables such as anxiety, depression, anger, and impulsivity. RESULTS: First, the scale had good internal consistency with a Cronbach's α of 0.88. Second, EFA indicated a single dimensionality of the BITe, and CFA demonstrated a reasonable fit for the single-factor model (comparative fit index=0.97, Tucker-Lewis Index=0.95, normed fit index=0.97, goodness-of-fit index=0.96, root mean square error of approximation=0.12, standardized root mean residual=0.03). Finally, the convergent validity analysis revealed a significant positive correlation with depression, anxiety, and anger, except for anger control, which is a sub-variable of anger. CONCLUSION: The results showed that the Korean version of the BITe had good psychometric properties, and might serve as a valuable tool for assessing irritability in Korean patients with psychiatric disorders.

Croatian Translation and Validation of the Patient Satisfaction with Nursing Care Quality Questionnaire (PSNCQQ).

Patient satisfaction is a crucial measure of the quality of healthcare, especially with regard to nursing services in hospital settings. Understanding and increasing patient satisfaction with nursing care is critical to improving overall healthcare and ensuring positive patient experiences during their hospital stay. The aim of this research was to evaluate the psychometric properties of the Croatian version of the Satisfaction with Nursing Care Quality Questionnaire (PSNCQQ), test the reliability and validity of the tool after translation, and investigate differences in patient satisfaction based on demographic variables, as well as their contribution to satisfaction with the quality of nursing care. After translation and adaptation, the Croatian version of the PSNCQQ was applied to 350 hospitalized patients (average age 51.19 years (range: 18-87)), of whom 194 (55.4%) were men and 156 (44.6%) were women. The results showed high internal consistency (Cronbach's α = 0.977) and confirmed the one-factor structure of the questionnaire, explaining 70.64% of the total variance. Confirmatory factor analysis supported the unidimensional model, showing strong fit indices (χ2 = 583.047, df = 149, p < 0.001, GFI = 0.861, AGFI = 0.818, NFI = 0.936, TLI = 0.946, CFI = 0.955, RMSEA = 0.080, PCLOSE < 0.001). In conclusion, the validation of the PSNCQQ in the Croatian language increases resources for evaluating and improving the quality of nursing care. This research lays the foundation for future studies and practical applications aimed at improving patient satisfaction and nursing care outcomes in Croatia, but there are also limitations to this study, including its one-institution scope, the possible influence of factors outside the current treatment on satisfaction, and the lack of comparison with objective clinical indicators.

Early Childhood Oral Health Impact Scale: Psychometric Evaluation in Portuguese Preschoolers.

Objective: to contribute to the validation of the Early Childhood Oral Impact Scale (ECOHIS) by studying its psychometric properties when applied to a Portuguese preschool population. Methods: Cross-sectional study conducted with children aged between three and five-years-old. The non-probabilistic sample included two preschools in the municipality of Lisbon. Children who agreed to participate and whose guardians signed the informed consent were included. Data collection included a questionnaire, administered to the parents, and an intraoral examination of the children. The questionnaire included the Portuguese version of ECOHIS. The intraoral examination included the caries diagnosis according to the World Health Organization criteria. Discriminant validity compared the ECOHIS score between children with and without caries experience (Mann-Whitney U-test). Cohen's d was calculated to estimate the magnitude of the difference. Reliability analysis included Cronbach's α and test-retest. Construct validity was analyzed by the correlation between the ECOHIS score and dmft (Spearman's correlation). A significance level of 5% was used. Results: The sample included 104 children (mean age 4.1 years). ECOHIS values were significantly different between children with and without caries (p=0.004). The Cohen's d was 0.84. The Cronbach's was 0.78, with no significant increase in value when eliminating any of the items. The test-retest showed significant correlation (r=0.76; p=0.01). There was a significant correlation between the ECOHIS score and caries experience (r=0.28; p=0.004). Conclusion: The Portuguese version of the ECOHIS showed good psychometric properties, indicating that it is a reliable and valid tool to measure the impact of oral health in preschool children.

Compilation of a self-management assessment scale for postoperative patients with aortic dissection.

Objective: The aim of this research was to compile a self-management assessment scale for patients with aortic dissection (AD). The questionnaire is useful in making the patient aware of the need for post-operative care in order to contribute to improving the outcome and quality of life. Methods: The initial version of the "postoperative self-management assessment scale for patients with aortic dissection" was developed using the Delphi expert consultation method based on qualitative research results, consultation of self-management-related literature, reference to the existing self-management scale, and self-efficacy theory, combined with the disease characteristics of AD. By using the convenience sampling method, a total of 201 patients with AD who had undergone surgery were selected as the research participants. The initial version of the scale was used for follow-up investigation, and the scale entries were evaluated and exploratory factor analysis carried out to form the formal version of the "postoperative self-management assessment scale for patients with aortic dissection." A total of 214 patients with AD after surgery were selected as the research participants. The formal version of the scale was used for follow-up investigation, and its reliability and validity were evaluated. Results: The formal version of the scale had 6 dimensions and 35 entries. The Cronbach's α coefficient for the total scale was 0.908, the split-half reliability was 0.790, and the test-retest reliability after 2 weeks was 0.471. The content validity index of the total scale was 0.963. Exploratory factor analysis yielded six common factors, and the cumulative contribution rate of variance was 66.303%. Confirmatory factor analysis showed that except for the incremental fit index, Tucker-Lewis index, and comparative fit index >0.85, slightly lower than 0.90, χ 2/df <3, root mean square of approximation <0.08, parsimonious goodness-of-fit index, and parsimonious normed fit index >0.50; all other model fitting requirements were satisfied, indicating that the model fitting was acceptable. Conclusion: We compiled the postoperative self-management assessment scale for patients with AD, which has demonstrated excellent reliability and validity and can be used as a tool to evaluate the postoperative self-management level in patients with aortic dissection.

Accuracy, concurrent validity, and test-retest reliability of pressure-based insoles for gait measurement in chronic stroke patients.

Introduction: Wearables are potentially valuable tools for understanding mobility behavior in individuals with neurological disorders and how it changes depending on health status, such as after rehabilitation. However, the accurate detection of gait events, which are crucial for the evaluation of gait performance and quality, is challenging due to highly individual-specific patterns that also vary greatly in movement and speed, especially after stroke. Therefore, the purpose of this study was to assess the accuracy, concurrent validity, and test-retest reliability of a commercially available insole system in the detection of gait events and the calculation of stance duration in individuals with chronic stroke. Methods: Pressure insole data were collected from 17 individuals with chronic stroke during two measurement blocks, each comprising three 10-min walking tests conducted in a clinical setting. The gait assessments were recorded with a video camera that served as a ground truth, and pressure insoles as an experimental system. We compared the number of gait events and stance durations between systems. Results and discussion: Over all 3,820 gait events, 90.86% were correctly identified by the insole system. Recall values ranged from 0.994 to 1, with a precision of 1 for all measurements. The F1 score ranged from 0.997 to 1. Excellent absolute agreement (Intraclass correlation coefficient, ICC = 0.874) was observed for the calculation of the stance duration, with a slightly longer stance duration recorded by the insole system (difference of -0.01 s). Bland-Altmann analysis indicated limits of agreement of 0.33 s that were robust to changes in walking speed. This consistency makes the system well-suited for individuals post-stroke. The test-retest reliability between measurement timepoints T1 and T2 was excellent (ICC = 0.928). The mean difference in stance duration between T1 and T2 was 0.03 s. We conclude that the insole system is valid for use in a clinical setting to quantitatively assess continuous walking in individuals with stroke.

Operational criteria application does not change clinicians' opinion on the diagnosis of mental disorder: a pre- and post-intervention validity study.

Objective: Our objective was to check if the ICD-10 operational criteria application changes non-operational, prototype-based diagnoses obtained in a real-life scenario. Methods: Psychiatry residents applied the diagnostic criteria of the ICD-10 as a "diagnostic test" to five outpatient patients they were already following who had a prototype-based diagnosis. Tests were used to ascertain whether changes in opinion were significant and if any of the diagnostic groups were more prone to change than others. The present paper is part of the study with UTN U1111-1260-1212. Results: Seventeen residents reviewed their last five case files, retrieving 85 diagnostic pairs of non-operational-based vs. operational-based diagnoses. The Stuart-Maxwell test did not indicate a significant opinion change (χ2 = 5.25, p = 0.39; power = 0.94) besides 30% of diagnostic changes. Despite not being statistically significant, 20.2% of all evaluations resulted in a change that would affect treatment choices. Using ICD-10 operational criteria slightly increased the number of observed diagnoses, but probably without clinical relevance. None of the non-operational diagnoses have a higher tendency to change with operational criteria application (χ2 = 11.6, p = 0.07). The female gender was associated with a higher diagnostic change tendency. Conclusion: Applying ICD-10 operational criteria as a diagnostic test does not induce a statistically significant diagnostic opinion change in residents and no diagnostic group seems more sensible to diagnostic change. Gender-related differences in diagnostic opinion changes might be evidence of sunk cost bias. Although not statistically significant, using operational criteria after diagnostic elaboration might help to deal with subjects without adequate treatment response.

Psychometric Analysis of the Obsessive-Compulsive Spectrum Self-Report and Social Anxiety Spectrum Self-Report in the Korean Population.

OBJECTIVE: The present study aimed to assess the psychometric properties of the Korean versions of the Obsessive-Compulsive Spectrum Self Report (OBS-SR) and the Social Anxiety Spectrum Self Report (SHY-SR) questionnaires, along with determining their optimal cut-off points in a Korean population. METHODS: The study included outpatients with obsessive-compulsive disorder (OCD) (n=86), or social anxiety disorder (SAD) (n=52), those with major depressive disorder (MDD) (n=27), and 33 healthy controls. Participants were administered the Korean versions of the OBS-SR and SHY-SR questionnaires. Clinical symptoms were also assessed with several self-rating scales. RESULTS: The Korean versions of the OBS-SR and SHY-SR demonstrated good internal consistency, test-retest reliability, and convergent validity. Both questionnaires effectively differentiated between individuals with OCD or SAD and normal controls or those with MDD. Receiver-operating characteristic analyses of the OBS-SR and SHY-SR yielded area under the curve values of 0.89 and 0.96 for Diagnostic and Statistical Manual of Mental Disorders, Forth Edition diagnosis, respectively, and showed optimal threshold values of 50 and 44. CONCLUSION: The Korean versions of OBS-SR and SHY-SR demonstrate good reliability and validity in assessing manifestations of obsessive-compulsive and social anxiety psychopathology in Korean populations.
