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.

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.

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.

Assessment of patients’ dental anxiety levels in the context of infectious diseases: development and validation of Musa Kazim’s Dental Anxiety Scale (MK-DAS)

ObjectivesThe study aimed to develop and validate a new scale called Musa Kazim’s Dental Anxiety Scale (MK-DAS) to measure dental anxiety in relation to infectious diseases.MethodsThe study utilized a cross-sectional design and recruited participants from Faculty of Dentistry, Altinbas University. The sample included 289 participants who were seeking dental treatment. The Modified Dental Anxiety Scale (MDAS) was employed for the purpose of assessing levels of dental anxiety. In contrast, the MK-DAS, comprised a series of seven inquiries specifically targeting concerns regarding the treatment procedure and the fear of contagion. The data was analyzed using various statistical methods, including descriptive statistics, exploratory factor analysis, criterion validity, cluster analysis for cut-off points, and test-retest reliability.ResultsThe factor analysis revealed that MK-DAS had a two-factor structure. The first factor consisted of five items related to various aspects of the treatment process (α:0.837), while the second factor included two items related to the fear of infectious diseases (α:0.747). The scale showed good reliability, as indicated by high Cronbach’s alpha coefficients for both factors. Strong positive correlations were found between MDAS and the first factor of MK-DAS (r = 0.857; p < 0.01), moderate positive correlations between MDAS and the second factor (r = 0.323; p < 0.01), and a strong positive correlation between MDAS and the overall of MK-DAS (r = 0.782; p < 0.01). Additionally, the cluster analysis yielded a cut-off score of 17 based on the k-means analysis. Moreover, test-retest reliability analyses indicated that dimension 1 (ICC: 0.904), dimension 2 (ICC: 0.840), and overall MK-DAS (ICC: 0.944) demonstrated high internal consistency.ConclusionThe MK-DAS is an innovative and modern dental anxiety scale that has been proven to be reliable and valid, surpassing the comprehensiveness of the MDAS.

Development and psychometric validation of the hospitalized patients' expectations for treatment scale-clinician version.

Patient safety management systems in general hospitals require a comprehensive tool for assessing the expectations of inpatients across different wards. This study aimed to develop and psychometrically validate a new scale, the hospitalized patients' expectations for treatment scale-clinician version (HOPE-C), to meet this requirement. We interviewed 35 experts and 10 inpatients while developing the HOPE-C scale. The scale was initially designed with three dimensions: clinicians' expectations regarding doctor-patient communication, clinicians' expectations regarding treatment outcome, and clinicians' expectations regarding disease management. We recruited 200 inpatients from a general hospital in China. At the same time, 51 clinicians were assigned to the enrolled patients who completed the HOPE-C to examine the reliability, validity, and psychometric characteristics of the questionnaire. We applied item analysis, assessed construct validity, evaluated internal consistency, and conducted a test-retest reliability analysis over 7 days. Both exploratory and confirmatory analyses supported a 2-dimensional structure, comprising doctor-patient communication expectations and treatment outcome expectations, with favorable model fit parameters (root mean square residual [RMR] = 0.042, root mean square error of approximation [RMSEA] = 0.049, comparative fit index [CFI] = 0.989, Tucker-Lewis index [TLI] = 0.984). Item analysis demonstrated appropriate item design (r = 0.744-0.961). The scale exhibited strong internal consistency, with Cronbach's α values of 0.884, 0.816, and 0.840 for the overall scale, the doctor-patient communication expectation subscale, and the treatment outcome expectation subscale, respectively. The 7-day test-retest reliability was 0.996 (p < 0.001). Our findings suggest that the HOPE-C is a reliable and valid assessment tool for measuring the expectations of inpatients in general hospitals. It effectively identifies patients' expectations concerning doctor-patient communication and treatment outcomes.

The Development and Validation of a Scale to Assess Perception of Physical Education Among University Students in China

This study aimed to develop and test a University Students’ Perceptions of Physical Education (PE) Scale. The study was conducted in three phases in a southwestern city in China from December 2021 to October 2022. In Phase 1, an item pool was constructed based on a literature review and semi-structured interviews. In Phase 2, expert evaluations and university student interviews were conducted to evaluate the content validity of the questionnaire. In Phase 3, a cross-sectional study was administered to university students. Composite reliability (CR) and average variance extracted (AVE) for internal consistency and test-retest reliability analyses were calculated for the stability reliability analysis. The validity evaluations included content, construct, and discriminant validity and an invariance test. The developed scale comprises 20 items covering six domains: habituated behavior in physical activity, self-efficacy in PE, attitude and experience in PE, skills and knowledge, classroom climate, and facilities, equipment and norms. Each domain’s CR and AVE values exceeded 0.7 and 0.5, respectively. The statistical indices of the final model were chi-square (χ2) = 458.227, degrees of freedom ( df) = 155, Comparative Fit Index = 0.957, Tucker–Lewis Index = 0.947, standardized root mean square residual = 0.061, and root mean square error of approximation = 0.066, supporting the reliability and viability of the scale. A scientific process was adopted in constructing the University Students’ Perceptions of PE Scale. High validity and reliability scores indicate the suitability of using this scale for further research.

Test of Oral Health Literacy in Adults (TOHLA): development and psychometric evaluation of a new scale.

This study aimed to develop and rigorously evaluate the Test of Oral Health Literacy in Adults (TOHLA) for the Iranian population, addressing the limitations of existing oral health literacy (OHL) measurement instruments and contributing to the literature on OHL assessment. The development of the TOHLA involved a qualitative approach, which included a comprehensive literature review and semi-structured interviews with a panel of 15 experts from diverse fields and 22 Iranian adults aged 18 to 64 years. The instrument was designed with 48 items categorized into four domains: cognitive skill, communication skill, media skill, and functional skill. Content validity was established through expert input and content validation indices. Construct validity was supported by factor analysis, and concurrent validity was assessed by comparing TOHLA scores with demographic variables. Internal consistency and test-retest reliability analyses were performed to assess the instrument's reliability. The psychometric evaluation of the TOHLA demonstrated strong content validity, construct validity, concurrent validity, internal consistency, and test-retest reliability. The instrument exhibited a high level of internal consistency, with a Cronbach's alpha coefficient of 0.81 for the entire scale. Test-retest reliability was satisfactory, with an intraclass correlation coefficient (ICC) of 0.83. Concurrent validity analysis showed statistically significant associations between OHL scores and demographic variables, supporting the instrument's overall performance. The TOHLA overcomes the weaknesses observed in existing instruments and offers a comprehensive tool with strong psychometric properties to assess the OHL of the Iranian adult population. Researchers, policymakers, and healthcare providers can utilize the TOHLA to address oral health challenges and enhance overall oral health outcomes among Iranian adults.

Strengthening pharmacy practice: Development and validation of the resilience scale

Background/Aim. Despite the demanding nature of their roles in community pharmacies and their critical importance to patient safety, healthcare professionals, including pharmacists, are often not covered by the Resilience Scale. Therefore, the aim of the study was to develop and validate a resilience scale specifically tailored for pharmacists working in community pharmacies. Methods. The study involved the development and validation of a scale aimed at assessing psychological resilience among community pharmacists. The domains and items of the scale were considered from the aspect of review-ing the available literature. Content validation by subject matter experts and subsequent computation of the content validity index ensured the scale?s content validity. Face validity assessment ensured alignment with the in-tended construct. The final scale was distributed to a sample of 504 community pharmacists, after which the scale was analyzed using statistical methods such as factor analysis, multiple regression, and reliability analysis. Additionally, test-retest reliability analysis was performed on 80 community pharmacists. Results. During the brainstorming sessions and focus groups, 95 items were generated within five domains - Confidence, Agility, Coping with stress, Interpersonal relations, and Developmental thinking. Following expert review and rigorous content and face validity analyses, 30 items with Content Validity Index and Face Validity Index values surpassing 0.80 were retained. The scale exhibited strong internal consistency, with Cronbach?s alpha exceeding 0.9. Factor analysis confirmed the five-factor structure, with each component displaying high factor loadings and significant variable loadings on only one component. Conclusion. The Resilience Scale emerged as a promising tool for assessing community pharmacists? resilience, demonstrating robust psychometric properties. The study contributed validity evidence concerning content and internal structure, thereby enhancing the scale?s credibility in evaluating resilience domains within the pharmacy profession.

The development and validation of the S-scan-parental self-management support (S-scan - PS): A self-reflection tool for child healthcare professionals.

Professionals providing self-management support to parents regarding the care for their child with a chronic condition nowadays is an important aspect of child healthcare. This requires professionals to orient themselves towards partnership and collaboration with parents. The aims of the current study were the development and validation of the S-Scan-Parental self-management Support (S-scan - PS) as a tool for healthcare professionals to reflect on their attitude and practices regarding the support for parental self-management. An existing instrument was adapted together with field experts for professionals to self-evaluate their support for self-management of parents. The resulting 36-item self-report questionnaire was filled in by healthcare professionals in the Netherlands working with children and their parents. Cognitive interviews, exploratory and confirmatory factor analysis (CFA), and test-retest reliability analysis were part of the development and validation process. In total, 434 professionals, including physicians, physiotherapists, occupational therapists, and nurses, from 13 rehabilitation institutes and 5 medical centres participated. The cognitive interviews with child healthcare professionals indicated adequate face and content validity. The S-scan - PS scale had acceptable internal consistency (0.71 ≤ α ≤ 0.91) for the total score as well as the domain scores. CFA showed acceptable root mean square error of approximation (RMSEA) model fit (0.066), though not on other tested goodness-of-fit indices. Test-retest reliability of the instrument was moderate with an average intraclass correlation coefficient (ICC) = 0.61. The S-scan - PS fulfils important psychometric criteria for use by child healthcare professionals to reflect on parental self-management support. Such self-reflection might help to improve their approach towards supporting self-management of parents in the care for their child with a chronic condition. Further research is needed into the construct validity and test-retest reliability of the instrument.

Factor analysis and evaluation of one-year test-retest reliability of the 33-item Childhood Trauma Questionnaire in Chinese adolescents.

The 33-item Childhood Trauma Questionnaire (CTQ-33) is a recently developed tool expanded from the 28-item Childhood Trauma Questionnaire (CTQ-28) to assess childhood trauma events, which showed good test-retest reliability over 2 weeks. However, little is known regarding the factor structure and long-term test-retest reliability of the CTQ-33. To fill such a gap, this study investigated the factorial validity of the CTQ-33 and test-retest reliability of the scale over a relatively long interval of 1 year. Data on demographics, the CTQ-33 scores, and mental health statuses such as depressive/anxiety symptoms were collected in Chinese adolescents (n = 188) twice across a one-year period. Results of the confirmatory factor analysis (CFA) revealed that the Chinese version of CTQ-33 has close factor validity when compared to the original CTQ-28 in college students. Furthermore, the total and most subscale scores of the CTQ-33 have fair to good test-retest reliability (intra-class correlation coefficients >0.6 for the total score, and > 0.4 for most subscales), except for the physical abuse subscale. Moreover, we replicated previous findings of significant positive relationships between levels of different childhood trauma subtypes using the CTQ-33. These findings provide initial evidence supporting that the CTQ-33 is overall reliable to assess childhood traumatic events in adolescents over relatively long intervals.

Spanish adaptation and validation of the Dula Dangerous Driving Index (DDDI).

The Dula Dangerous Driving Index (DDDI) is a widely used questionnaire that measures the tendency to drive dangerously on the road through three different types of behaviors: aggressive driving, risky driving, and experiencing negative emotions while driving. This study aimed to develop a Spanish version of the DDDI and verify the reliability and validity of this questionnaire in the Spanish population. A community sample of 2174 Spanish participants (51.1% male; age range: 18-79 years) completed the 28-item Spanish version of the DDDI. Confirmatory factor analysis revealed that a three-factor model fitted adequately to the data. Analysis of internal consistency, test-retest reliability, and convergent validity showed that the Spanish adaptation of the DDDI had good psychometric properties and retains the theoretical consistency of the original scale. Gender and age differences were observed. The Spanish version of the DDDI can be considered a good instrument for assessing dangerous driving behavior, thus contributing to the cross-cultural study of these types of behaviors and the possible development of intervention programs aimed at reducing road traffic accidents.

Psychometric evaluation of the Danish version of the Pain Self-Efficacy Questionnaire in patients with subacute and chronic low back pain.

The Pain Self-Efficacy Questionnaire (PSEQ) is a widely used patient-reported outcome measure designed to assess the level of pain self-efficacy in patients with low back pain (LBP). Although the PSEQ has been translated into Danish, its measurement properties remain unknown in patients with subacute and chronic LBP in Danish outpatient clinics. The aim of this study was to investigate the construct validity, internal consistency, test-retest reliability, and measurement error of the Danish version of the PSEQ in a group of Danish patients with subacute and chronic LBP in a hospital outpatient setting. Patients with LBP referred to two Danish outpatient clinics were recruited for this study. Two days after the consultation, the participants were emailed a link to a survey that included the following outcome measures: the PSEQ, the Oswestry Disability Index, the Numeric Pain Rating Scale, and the Tampa Scale of Kinesiophobia. Five days after completion of the survey, a new survey that included the PSEQ was sent to the participants. In total, 109 participants were included for the analysis of construct validity and internal consistency, with 94 participants included for the analysis of test-retest reliability and measurement error. Construct validity was found to be high and internal consistency was acceptable, with Cronbach's alpha = 0.93 (95% confidence interval [CI] = 0.91-0.93). Test-retest reliability was found to be good, with an intraclass correlation coefficient (ICC2.1) of 0.89 (95% CI = 0.82-0.92). The standard error of measurement was calculated to be 4.52 and the smallest detectable change was 12.5 points. The Danish version of the PSEQ showed acceptable measurement properties in terms of construct validity, internal consistency, and test-retest reliability in a group of patients with subacute and chronic LBP. However, further studies are needed to investigate other aspects of the measurement properties.
