Psychometric Analysis and Structural Invariance of the Life Orientation Test-Revised (LOT-R) Across Genders in a Latin American Sample

Dispositional optimism is associated with various health and well-being outcomes, underscoring the importance of having valid assessment tools. The Life Orientation Test-Revised (LOT-R) is widely used for this purpose, but its factorial structure is still debated. This study aimed to validate the LOT-R’s factorial model and assess its Spanish version’s psychometric properties with a sample of 687 participants. Bayesian and DWLS Confirmatory factor analysis favored a Hierarchical model and a Bifactor MC model. All items showed good discrimination and correlation. The optimism factor had a reliability of 0.72, while the pessimism factor was 0.6. The criterion validity of the two factors was established through correlation analysis with the PANAS scale. Metric invariance across gender was not achieved, and items 4 and 5 exhibited differential item functioning (DIF), suggesting that gender differences on this scale may be attributed to variations in item interpretation rather than true differences in the underlying construct. The factorial structure of the LOT-R indicates the presence of a general factor encompassing both optimism and pessimism. While the optimism-related items exhibit strong psychometric properties and can be reliably used as a standalone factor, the pessimism-related items fail to meet the required reliability thresholds for independent use.

An Evaluation of the Psychometric Properties of the Short Form of the Speech, Spatial and Qualities of Hearing Scale in Swedish: Online Versus Paper-and-Pen.

The purpose of this study was to examine the psychometric properties of the Swedish short form of the Speech, Spatial and Qualities of Hearing Scale (SSQ12) and investigate whether the paper-and-pen and online formats could be used interchangeably. Individuals with and without hearing problems were invited to participate in this study. The participants (N = 125) were randomized into four groups: paper-paper, online-online, paper-online, and online-paper. All participants completed the Swedish SSQ12 twice. Principal components analysis revealed one component. Statistical analysis revealed good psychometric properties. Administration formats were compared using repeated-measures analysis of variance, which revealed no statistically significant differences. The results indicate that the Swedish SSQ12 is possible to use in paper-and-pen and online formats interchangeably. The questionnaire has potential to be used by Swedish audiologists seeking to understand the individual experience of hearing loss or to evaluate hearing rehabilitation. To further understand the possible differences and to broaden the use and understanding of the SSQ12, future studies should aim to determine the minimal clinically important difference for the SSQ12.

Instruments for the assessment of quality of life in children and adolescents with Down syndrome: a scoping review

The construct of quality of life (QoL) includes aspects of health and well-being of people. Down syndrome [DS] or trisomy 21 is one of the most common congenital anomalies. DS is characterized by motor and cognitive alterations that affect health and QOL of both the child and caregiver.In pediatrics, there are various instruments to assess Health-Related Quality of Life (HRQoL) and QoL. The advantage of these instruments is that they can be implemented in any type of disease and population in general. However, they may have certain disadvantages, such as the difficulty in evaluating specific aspects of each disease or condition related to Down syndrome. The aim of this study was to identify 1: instruments used to assess quality of life in children with Down syndrome. 2: psychometrics properties of instruments validated in children with Down syndrome to assess quality of life.Methods A Scoping review was conducted to identify instruments used in children and adolescents with Down syndrome, and a second systematic searched psychometric properties of these instruments. The electronic databases PubMed, Embase, Epistemonikos and other sources were explored with a search strategy that included keywords such as “Down syndrome,” “Quality of life” or “Life Quality,” “Health-Related Quality of Life” and psychometrics properties. The quality of the included studies was evaluated using the COSMIN (Based Standards for the Selection of Health Measurement Instruments) methodology.Results Twenty-seven studies were selected that used twelve instruments to evaluate quality of life in children or adolescents with Down syndrome. Two of the twelve evaluated quality of life and ten health-related quality of life. In the second search, ten studies reported the psychometric properties of six instruments evaluated in minors with Down Syndrome.Conclusion There is limited information available regarding the psychometric properties of instruments used to assess quality of life, particularly health-related quality of life. Commonly employed instruments in this area include the PedsQL 4.0 and KIDSCREEN. Notably, while the PedsQL 4.0 lacks specific evaluation in children with DS, data from KIDSCREEN assessments are inconsistently reported. Rigorous evaluation of the performance of Kidslife and Kidslife Down in clinical settings is necessary, or the development of new instruments tailored for children with DS is warranted to comprehensively assess quality of life in clinical settings.

Fidelity, acceptability, and feasibility of the revised functional autonomy measurement system for hospitalised people: An implementation study.

The revised functional autonomy measurement system (SMAF-R) is an outcome measure of activity performance and resource needs. This study aimed to measure the implementability of the SMAF-R as a routine outcome measure in acute and subacute inpatients. This was a mixed-methods implementation study. Occupational therapists were asked to complete the SMAF-R in hospitalised people with an anticipated length of stay greater than 48 hours over a 12-month period (n= 13,348). A baseline audit of SMAF-R completion rates was conducted, and behaviour change interventions were delivered over 12 months. The Implementability of Healthcare Interventions conceptual framework was used to evaluate fidelity (completion rates), acceptability (staff survey with quantitative and qualitative responses), and feasibility (change in SMAF-R scores from admission to discharge). Quantitative and qualitative (analysed thematically) data were integrated. Occupational therapists and other staff working to improve outcome measure completion within the electronic medical record and other allied health teams were consulted when developing and delivering behaviour change interventions. Peak completion of the SMAF-R did not meet an 80% fidelity success rate (admission: 32% in acute and 66% in subacute; discharge: 12% in acute and 48% in subacute). Two thirds of occupational therapists reported the SMAF-R was an acceptable measure to use, but only 38% liked using it. Thematic analysis revealed three themes: (1) A greater understanding of the relevance of the SMAF-R influenced acceptability; (2) using the SMAF-R within an electronic medical record may facilitate completion; and (3) it takes more time to complete SMAF. Patients made clinically significant improvements in SMAF-R scores during their hospital stay (median difference 16.5 [6.5-27.0], p< 0.001, n= 764). Although most occupational therapists reported the SMAF-R was acceptable, there were mixed opinions regarding the relevance of the SMAF-R in this setting, which may have impacted fidelity. Additional prompting and training (especially regarding understanding SMAF-R relevance to practice) may assist with improving SMAF-R completion. Further research is required to assess the psychometric properties of the SMAF-R in the hospital environment. The revised functional autonomy measurement system (SMAF-R) is an assessment tool used to measure performance in everyday activities (such as showering) and the resources needed to complete these tasks (e.g., a shower chair or someone's help). Occupational therapists can use it at the start of a patient admission and again at the end in different hospital settings to assess patients' needs and see if they improve. This study aimed to measure (1) how often occupational therapists use the SMAF-R with patients in hospital, (2) how acceptable occupational therapists find the SMAF-R, and (3) whether the SMAF-R shows changes in patients' abilities during their hospital stay. Before the study, usual completion of the SMAF-R was measured, and it was found to be completed in less than 1% of patients. Strategies were introduced to improve SMAF-R completion over 12 months. After this, completion of the SMAF-R improved to between 9% and 38% in different hospital settings. Changes in SMAF-R scores showed that patients improved during their time in hospital. Most occupational therapists reported the SMAF-R was an acceptable measure, but less than half liked using it. The low completion rates suggested that either the SMAF-R was not fit for purpose in this setting or that more support is needed to increase completion.

Psychometric validation of the Chinese version of the longer-term Unmet Needs after Stroke monitoring tool for stroke patients

Purpose This study aimed to translate, adapt, and test the psychometric properties of the Longer-term Unmet Needs after Stroke (LUNS) monitoring tool for Chinese stroke patients. Materials and Methods The LUNS monitoring tool was translated and cross-culturally adapted using the Functional Assessment of Chronic Illness Therapy translation methodology and two rounds of expert consultation. A cross-sectional study was conducted to test the validity and reliability of the Chinese version of the tool from April to October 2023 in Xi’an. Results The Chinese version of the LUNS monitoring tool had a Cronbach’s alpha value of 0.702 and the ICC was 0.732 (p < 0.001). The I-CVIs were above 0.90 and the S-CVI/Ave was 0.983. The factor analysis extracted eight factors, collectively accounting for 66.283% of the data variance. The correlation coefficient between the LUNS and WSO needs assessment questionnaire was 0.105 (p = 0.019). Conclusions The study confirmed good reliability and validity of the Chinese version of the LUNS monitoring tool in measuring the prevalence and level of unmet need in stroke patients. It will help identify the unmet needs of stroke patients, and to guide rehabilitation service response during individual patient consultations, facilitate service development, and inform commissioning decisions.

Hedonic vs. Eudaimonic Ways of Living on the Path to Well-Being and Psychological Distress: Turkish Validation of HEMA-R

The Hedonic and Eudaimonic Motives for Activities-Revised (HEMA-R) measures eudaimonic, hedonic, hedonic pleasure, and hedonic comfort motivations. We tested the psychometric properties of the HEMA-R among Turkish-speaking university students (N = 255) and adults (N = 460). Confirmatory factor analyses among university students demonstrated both two-factor and three-factor solutions of the HEMA-R, while confirmatory factor analyses among adults identified a three-factor solution. Internal consistencies of the HEMA-R were largely over α and ω &gt; .80. In both samples, eudaimonic motivation always had at least slightly more positive associations with well-being indicators compared to hedonic motivation, hedonic pleasure motivation, and hedonic comfort motivation, while having negative weak relationships in half of the analyses with ill-being indicators. Hedonic motivation had mostly weak positive associations with the majority of well-being outcomes, while surprisingly having weak positive associations with several indices of ill-being. Hedonic pleasure motivation had weak positive associations with the majority of well-being indicators, and hedonic comfort motivation did not have any association with some of the well-being indicators. They predominantly had no associations with ill-being indicators. Eudaimonic and hedonic indicators of motivation both related to need satisfaction and meaning in life indicators. Implications are discussed for future research.

The Children’s Somatic Symptoms Inventory-8: Psychometric Properties of a Brief Measure of Somatic Distress

Background: Children often present to primary and specialty care clinics with multiple somatic symptoms of nonspecific origin that can be highly distressing and prompt significant health service use. We evaluated the psychometric properties of the eight-item Children’s Somatic Symptoms Inventory (CSSI-8) as a brief measure of somatic distress that could be easily integrated into clinical systems. Method: Eight items from the 24-item CSSI were selected based on their representation of multiple bodily systems, association with high base rates, and ability to maximize the separation of the items’ Rasch measure scores. The psychometric quality of the eight-item scale was evaluated in 876 pediatric patients with chronic abdominal pain and a nonclinical sample of 954 school children using methods from three psychometric models (the classical test theory, Rasch modeling, and confirmatory factor analysis). Results: The CSSI-8 showed good measurement properties on an extensive array of psychometric criteria, had adequate Rasch person separation reliability for a brief instrument (rsep = 0.74–0.75), and distinguished between clinical and nonclinical youth. Girls in both groups had significantly higher CSSI-8 scores than boys. Norms for the clinical sample are presented. Conclusions: The CSSI-8 is a psychometrically sound measure suitable for use as a brief dimensional assessment of pediatric somatic distress.

Psychometric evaluation of the persian version of Existential Concern Questionnaire (ECQ) in Iranian general population: a cross-sectional study

BackgroundExistential anxiety is the anxiety that goes beyond objective threats and is related to a person’s existence. Due to the lack of appropriate instrument to measure all five domains of existential anxiety in the Iranian population, this study aimed to examine the psychometric properties of the Existential Concern Questionnaire (ECQ) in the Iranian general population.MethodsThis online cross-sectional survey was conducted from October 9 to December 11, 2023 in Tehran, Iran. We used an Internet-based data collection method. A total of 549 participants completed the questionnaires. The research instruments included the Existential Concern Questionnaire, Existential Anxiety Questionnaire, Meaning in Life Questionnaire, Short version of the Beck Depression Inventory, Intolerance of Uncertainty Scale-12, and Death Attitude Profile Revised. Confirmatory factor analysis, convergent validity, and concurrent validity were used to measure the validity of ECQ. Cronbach’s alpha and split-half methods were employed to assess the reliability of the ECQ.ResultsConfirmatory factor analysis showed a good fit of the unidimensional model (CMIN/DF: 2.802, RMR: 0.066, GFI: 0.914, NFI: 0.911, CFI: 0.941, PNFI: 0.769, PCFI: 0.794, RMSEA: 0.057). Also, the correlation of ECQ with other variables was as expected except for the search for meaning in life (r: 0.010, P = 0.808), which indicates the validity of this questionnaire. The reliability of the questionnaire was also acceptable (Cronbach’s Alpha: 0.935).ConclusionsThe results supported the validity and reliability of the ECQ. The mentioned questionnaire can be used in Iranian general population. Considering the importance of existential anxiety in etiology of some disorders, it is suggested that the future studies focus on validation of the ECQ in different clinical samples and cultures.

Comparing the properties of traditional and novel approaches to the modified Rankin scale: Systematic review and meta-analysis.

The Modified Rankin Scale (mRS) is the most commonly used functional measure in stroke research but is limited by inter-rater reliability (IRR). Various interventions to improve mRS application have been described. We aimed to compare properties of differing approaches to mRS assessment. Multidisciplinary databases (MEDLINE, EMBASE, Health and Psychosocial Instruments [OVID], CINAHL, PsycINFO [EBSCO]) were searched for adult human stroke studies describing psychometric properties of mRS. Two researchers independently screened 20% titles and abstracts, reviewed all full studies, extracted data, and conducted risk of bias (ROB) analysis. Primary outcomes for random-effects meta-analysis were IRR measured by kappa (K) and weighted kappa (KW). Validity and inter-modality reliability measures (Spearman's rho, KW) were also summarised. From 897 titles, 46 studies were eligible, including twelve differing approaches to mRS, 8608 participants. There was high ROB in 14 (30.4%) studies. Overall, reliability was substantial (n = 29 studies, K = 0.65, 95% CI: 0.58-0.71) but IRR was higher for novel approaches to mRS, for example, the Rankin Focussed Assessment (n = 2 studies, K = 0.94, 95% CI: 0.90-0.98) than standard mRS (n = 13 studies, K = 0.55, 95%CI:0.46-0.64). Reliability improved following the introduction of mRS training (K = 0.56, 95% CI: 0.44-0.67; vs K = 0.69, 95% CI: 0.62-0.77). Validity ranged from poor to excellent, with an excellent overall concurrent validity of novel scales (n = 6 studies, KW = 0.86, 95% CI: 0.75-0.97). The agreement between face-to-face and telephone administration was substantial (n = 5 studies, KW = 0.80, 95% CI: 0.74-0.87). The mRS is a valid measure of function but IRR remains an issue. The present findings are limited by a high ROB and possible publication bias. Interventions to improve mRS reliability (training, structured interview, adjudication) seem to be beneficial, but single interventions do not completely remove reliability concerns.

Parenting styles as predictors to female students’ sexual promiscuity in tertiary institution in delta state

This study investigated the relationship between parenting styles and female students’ sexual promiscuity in tertiary institutions in Delta State. The study was led by two research questions and two hypotheses. The study used an ex-post facto research design with a correlational technique. The population comprised all female students of tertiary institutions in Delta Central Senatorial District with a total sample of 1,566 students. Questionnaire was used as instrument of data collection. The questionnaire was validated by experts’ judgement and factor analysis, with a sound psychometric property indicating that the instrument is valid and reliable. The data obtained were analysed with the aid of regression statistics at 0.05 level of significance. The result showed a significant relationship between parenting styles and sexual promiscuity and that the relationship can be moderated by socio-economic status of parents. The study recommended amongst others that Parents should improve on their relationship with their adolescents and choose the right parenting style that will help the adolescents to abstain from risky sexual behaviour.

Psychometric properties of the Persian version of the workplace fun scale among nurses: a cross-sectional study

Previous research has highlighted the importance of workplace fun in enhancing employee satisfaction and performance, particularly in high-stress professions like nursing. However, a notable gap exists in understanding how workplace fun is perceived and measured among nurses in Persian-speaking countries. This study addresses this gap by translating the Workplace Fun Scale and assessing its psychometric properties among nurses. The findings will provide insights into the scale’s applicability in these contexts and pave the way for healthcare organizations to significantly explore ways to enhance nurses’ enjoyment of work in Persian-speaking countries. This survey, which involved 321 nurses from medical education centers in Ardabil, was conducted with a meticulous and rigorous methodology. Standard questionnaires collected the data, including a demographic form and the translated Workplace Fun Scale. The study examined the three aspects of workplace fun: fun activities, coworker socializing, and manager support for fun. Confirmatory factor analysis was used to validate the structure, and reliability was assessed through retest coefficients, Cronbach’s alpha coefficients, and composite reliability coefficients. The data were analyzed using SPSS version 14 and LISREL version 8.8, ensuring the highest research standards. The validity of both form and content was confirmed through translation and reverse translation. The Workplace Fun Scale showed high internal consistency and reliability, with significant Cronbach’s alpha coefficients, composite reliability, and two-week retest coefficients of 0.859, 0.885, and 0.459, respectively (all at the p < 0.01 level). Fit indices, including GFI (0.97), AGFI (0.94), CFI (0.99), NFI (0.98), TLI (0.97), and SRMR (0.04), indicated a good fit of the measurement model, confirming the validity of the scale in assessing workplace fun. The confirmatory factor analysis results indicated that the translated version of the workplace fun scale, adapted from Tews, exhibited a robust factor structure and internal homogeneity within the Iranian sample. Furthermore, the scale demonstrated positive internal validity and reliability in Persian translation. These findings suggest that the scale possesses acceptable psychometric properties, making it a valuable tool for assessing workplace fun among nurses in Persian-speaking countries.

Are you really satisfied in life? Developing a scale on life satisfaction

PurposeThis study attempted to measure life satisfaction and developed a scale to measure its dimensions with the required psychometric properties (validity and reliability). In today’s scenario, organizations are focusing on life satisfaction by helping employees to maintain their work-life balance. Therefore, this paper aims to develop a robust scale of life satisfaction.Design/methodology/approachThe methodology consists of three broad stages: item generation, scale development, and validity. Using the sample of 198 working executives, this study used the exploratory factor analysis (EFA) and concluded the four dimensions of life satisfaction: work satisfaction, family satisfaction, societal satisfaction and self-satisfaction.FindingsThe results provide academicians and practitioners with new insight and dimensions of life satisfaction. The result of this study shows that life satisfaction has societal satisfaction, family satisfaction, job satisfaction and self-satisfaction dimensions.Practical implicationsThis study will provide practitioners with new dimensions to measure life satisfaction. They can help employees achieve life satisfaction across four different factors. This will enable more employee satisfaction, an increase in retention rate and an increase in employee performance. Furthermore, this study provides implications from a policy perspective to design the business policy by considering life satisfaction as an important part of formulating and implementing human resource policies.Originality/valueThis study is unique in terms of exploring the dimensions of life satisfaction in a structured manner and establishing the psychometric properties as construct, content, and criterion validity along with reliability. This scale can be further used in future research to measure the life satisfaction construct.

Psychometric Properties of the TWente Engagement with Ehealth Technologies Scale (TWEETS) Among Patients with Hypertension in Italy.

Engagement with mobile health (mHealth) technologies among patients with hypertension is linked to reduced blood pressure and improved patient understanding of the condition. This study aimed to evaluate the psychometric properties (validity and reliability) of the TWente Engagement with Ehealth Technologies Scale (TWEETS) in an Italian cohort with hypertension. This study is the first attempt to evaluate the psychometric characteristics of the TWEETS in this population. The study was conducted in three phases. The first phase encompassed the translation and cultural adaptation of the TWEETS to the Italian setting. The second phase involved an expert panel evaluating the instrument's face and content validities. The third phase wasa cross-sectional study aiming to test construct validity and reliability. Adults diagnosed with hypertension were eligible for participation. Additional inclusion criteria included stable antihypertensive treatment for at least 2 weeks before enrolment and the provision of written informed consent. Patients were taught how to use two mHealth devices using the teach-back method. A total of 131 patients were enrolled. Exploratory and confirmatory factor analyses revealed that the TWEETS had a one-factor structure and a good level of fit. Cronbach's alpha coefficients suggested good internal consistency. The findings indicate that the TWEETS is a valuable tool for assessing the engagement of patients with hypertension with mHealth devices. Further assessment is needed in various cohorts to confirm the psychometric equivalence of the construct across different groups with hypertension.

Design and evaluation of a questionnaire to assess learners’ understanding of quantum measurement in different two-state contexts: The context matters

The teaching and learning of quantum physics has recently become a topic of increasing interest in physics education research. In particular, the study of two-state systems is gaining importance as a means of teaching quantum physics at various educational levels. Meanwhile, a number of approaches have been developed that are also suitable for high school students. It can be assumed that the different approaches have different degrees of effectiveness in teaching central quantum concepts. However, suitable evaluation instruments to test this are still lacking. Therefore, as a first step, a short questionnaire on quantum measurement, suitable for both research and classroom use, was developed in several steps. First, a questionnaire with open and closed items was created and piloted with a total of N=120 learners. The responses were evaluated qualitatively using a comprehensive coding manual, which provided insights into learners’ conceptions. These results led to the development of an eight-item questionnaire that could be adapted to different teaching approaches. This questionnaire was subjected to expert review and, finally, successfully tested for its psychometric properties with a sample of N=201 learners. Overall, our results provide initial empirical evidence that context (i.e., which two-state approach is used) does matter for student learning, but in general, two-state approaches appear to be particularly conducive to learning quantum concepts (specified in this article for quantum measurement) compared to traditional instruction.

Measuring health-related quality of life in a Chinese Mainland adolescent population: psychometric properties of the Mandarin Chinese self-reported KIDSCREEN-27 and KIDSCREEN-10 index

BackgroundThe self-reported KIDSCREEN questionnaires are ideal for capturing children’s and adolescents’ health-related quality of life (HRQoL) and have gained worldwide popularity. Responding to demands for the concise nature of KIDSCREEN among Chinese Mainland researchers and practitioners, this study aimed to evaluate the psychometric properties of the Mandarin Chinese self-reported KIDSCREEN-27 (KS-27) and KIDSCREEN-10 index (KS-10), which are short versions of the self-reported KIDSCREEN-52 (KS-52).MethodsThis study reanalyzed the validation dataset of the Mandarin Chinese self-reported KS-52. The dataset originated from a cross-sectional survey conducted in Weifang City, the Chinese Mainland, from October to November 2016. Adolescents aged 11–17 years (N = 4385) were surveyed, and sub-samples (N = 841) were retested. Statistical analyses were conducted on the feasibility, item and dimension properties, reliability, and validity of the Mandarin Chinese self-reported KS-27 and KS-10.ResultsIndirect evidence from the Small Group Pilot Survey indicated that the Mandarin Chinese self-reported KS-27 and KS-10 can be completed on average in less than 12.33 mins. Their response rate exceeded 90% regardless of the unit- and item (dimension)-level. The psychometric properties of items and dimensions were likewise found to be satisfactory. Internal consistency was robust with inter-item and item-total correlations (0.173–0.873, 0.422–0.786), Cronbach’s alpha (0.786–0.881), Guttman’s lambda-2 and - 6 (0.807–0.889, 0.829–0.896), and McDonald’s omega (0.725–0.886). Test–retest reliability at both item- and dimension-level was excellent, with intraclass correlation coefficients (ICCs) of (0.590–0.696, 0.785–0.842); standard error of measurements (SEMs) of (0.352–0.635, 0.949–1.949). Confirmatory factor analysis (CFA) confirmed their five- and one-dimensional structures, albeit with slight modifications. Moreover, the multi-group confirmatory factor analysis (MG-CFA) substantiated their configural and metric invariance across gender and grade groups. Convergent validity was robust, with stronger correlations observed with comparable dimensions of the Mandarin Chinese self-reported PedsQL™ 4.0, while discriminant validity was evident with low correlations observed with less comparable dimensions. The known-group validity was mainly supported by medium to large effect sizes concerning differences in socioeconomic status (η2 = 0.07–0.17, Cohen’s d = 0.55–1.03) and mental health status (η2 = 0.09–0.40, Cohen’s d = 0.73–1.83). The Mandarin Chinese self-reported KS-52 served as the criterion; the ICCs between the Mandarin Chinese self-reported KS-27 and KS-10 and their comparable dimensions were stronger, indicating robust criterion validity.ConclusionsThe Mandarin Chinese self-reported KS-27 and KS-10 demonstrated excellent psychometric properties, indicating their good potential for measuring HRQoL for children and adolescents in the Chinese Mainland.

Turkish Version of the Norwich Patellar Instability Score: Minimal Detectable Change among Patients with Traumatic Patellar Dislocation

Objective: This study aimed to calculate the minimal detectable change (MDC) in the Norwich Patellar Instability score (NPI) and validate the score for Turkish-speaking individuals with patellar instability. Method: Sixty-four patients (mean age 21.87 ± 9.44 years) who had experienced at least one patellar dislocation during athletic activities participated in the study. The Turkish version of the NPI (NPI-T) was evaluated for reliability and internal consistency. The Minimal Detectable Change was calculated as an overall value for the participants. MDC was calculated based on the standard error of measurement (SEM) and the selected confidence level (ICC) for the study population. Pearson's correlations were examined to assess construct validity between the Kujala Patellofemoral Disorder score and the Lysholm Knee Score. Result: The MDC for the NPI-T was 17.29, with a SEM of 6.24. The score demonstrated high internal consistency, with a Cronbach’s alpha value of 0.85, indicating substantial reliability. The consistency of measurements was excellent, with an ICC2,1 of 0.95. Additionally, the NPI-T score exhibited a strong negative correlation with both the Kujala (r = -0.85, p &lt; 0.001) and Lysholm (r = -0.89, p &lt; 0.001) scores. A floor effect was observed, but no ceiling effect was present. Conclusion: The study confirms that the NPI-T demonstrates strong psychometric properties, with high internal consistency and excellent reliability, as evidenced by its low MDC and SEM. The use of the NPI-T as a reliable and valid tool for assessing patellar instability in patients with patellar dislocation will provide valuable information to clinicians.

Measuring depressive symptoms among Latinos in the US: a psychometric evaluation of the CES-D Boston form.

We present a psychometric evaluation of the Center for Epidemiologic Studies Depression Boston Form (CES-D-B) for use with different Latino subgroups as there is inconsistency regarding its performance across subgroups of Latinos, a large and rapidly growing cultural group in the United States. We evaluated the reliability and structural validity of the scores generated by the CES-D-B using four distinct Latino samples residing in US: Mexicans, Venezuelans, Cubans, and "other Latinos" (total N = 1033). To further explore structural validity of CES-D-B scores, we conducted measurement invariance analyses across different countries of origin, gender groups, educational levels, and languages of assessment (English, Spanish). For all four samples, CES-D-B scores were highly reliable as indicated with the coefficients ranging from 0.82 to 0.88, and the factor structure provided an adequate fit to the data with the fit indices CFI/TLI ranging from 0.96 to 0.99, RMSEA estimates between 0.02 and 0.07, and SRMR estimates between 0.02 and 0.04. While measurement invariance analyses for different educational levels indicated scalar invariance across all samples, the same level of measurement equivalency was achieved only for Mexicans and Venezuelans with varying gender and languages of assessment. The findings indicated that CES-D-B scores are internally consistent, possess a strong four-factor structure, and have somewhat equivalent psychometric properties across diverse Latino groups. Findings from this study highlight the importance of considering gender and languages of assessment when assessing depressive symptoms of various Latino subgroups.

Translating and validating the Ghosting Questionnaire into Arabic: results from classical test theory and item response theory analyses

BackgroundGhosting refers to the sudden cessation of communication in interpersonal relationships. Ghosting has gained attention as a phenomenon commonly encountered in the context of digital communication. Earlier studies on ghosting mostly focused on Western societies while, in Arab societies, research into this practice has yet to be initiated. The current study aimed to address this gap by translating and validating the commonly used Ghosting Questionnaire (GHOST) into Arabic.MethodsThe translation process involved forward and back translation, expert review, and pilot testing to ensure linguistic and cultural equivalence. A convenience sample of 607 participants from Bahrain, Egypt, Jordan, Oman, and Tunisia completed the Arabic version of the GHOST. Statistical analyses, including reliability testing and confirmatory factor analysis, were conducted to assess the psychometric properties of the instrument.ResultsThe Arabic version of the GHOST demonstrated high reliability. The Cronbach’s alpha (α = 0.87) and McDonald’s omega (ω = 0.87) coefficients indicated strong internal consistency. Test-retest reliability coefficients confirmed the stability of the responses over time (ICC 0.89, p < 0.001). CFA supported a single-factor structure in alignment with the conceptual framework of the original English version.ConclusionsThe successful translation and validation of the GHOST into Arabic provide researchers with a reliable tool for investigating ghosting behavior within Arab societies. Future research endeavors can build upon these findings to explore the psychological implications of ghosting. Researchers can now also develop culturally sensitive understanding of online dating and related practices in Arab communities.

COPD empowerment scale: a scale development and validatıon study

Abstract Background The fact that COPD symptoms seriously affect daily life makes it different from other chronic diseases. The purpose of this study was to develop the COPD Empowerment Scale and test its psychometric properties. Methods This study, carried out with a methodological design, was carried out in a Chest Diseases Hospital in Istanbul, Turkey, between June 2023 and March 2024. A scale item pool was created by literature review and semi-structured interviews with COPD patients, and opinions were obtained from 16 experts. The draft scale, consisting of 55 items, was applied to 30 COPD patients as a pilot study. The draft scale was applied to 275 COPD patients and its psychometric properties were tested. The validity of the scale was evaluated by Content Validity Index (CGI) and exploratory and confirmatory factor analysis. Its reliability was evaluated by internal consistency analysis (Cronbach Alpha coefficient), item-total score correlations and test-retest analyses. Statistical significance level was accepted as p &amp;lt; 0.05. Results The KGI of the scale was found to be 0.97. The draft scale was transformed into a scale with five sub-dimensions and 31 items as a result of exploratory factor analysis. Cronbach’s Alpha value of the total scale is 0.896, and its sub-dimensions Cronbach’s Alpha values are; knowledge and understanding was found to be 0.731, access to health services was 0.816, self-efficacy was 0.719, symptom management was 0.842, and psycho-social coping was 0.728. Factor loadings of all items were 0.40 and above. As a result of confirmatory factor analysis, χ2 /df (2.59), RMSEA (0.076), NFI (0.92), NNFI (0.95), SRMR (0.03) and CFI (0.95) measurements are within the desired fit values. In the test-retest reliability study of the scale, the Pearson moment correlation coefficient was found to be rᵪᵪ=.996 (p&amp;lt;.01). Conclusions The COPD empowerment scale was found to be psychometrically valid and reliable. Key messages • The developed scale is a valid and reliable tool to determine the reinforcement needs of COPD patients. • The scale can be used to evaluate the effectiveness of empowerment initiatives.
