The reliability and validity of the multidimensional scale of perceived social support (MSPSS) in mothers of children with developmental disabilities in Saudi Arabia

Academic procrastination, defined as the intentional delay of important tasks, is a frequent phenomenon among university students and is associated with low performance, stress, and anxiety. The Tuckman Academic Procrastination Scale (TPS) is a widely used psychometric tool to assess this behavior. Although it has been validated in several countries, there is no empirical evidence regarding its validity and reliability in the Ecuadorian context, which limits its use for assessment and intervention. To psychometrically validate the Ecuadorian version of the TPS (TPS-E) in university students, assessing its factor structure, reliability, and cultural adequacy for measuring academic procrastination. An instrumental design was used with a non-probabilistic sample of 1,007 students (39.9% women; Mage = 21.88; SD = 3.69) from a private Ecuadorian university. The Spanish adaptation (Argentinean) was linguistically reviewed and applied using a 16-item Likert-type scale. Confirmatory Factor Analysis (CFA) with the DWLS estimator on a polychoric correlation matrix was conducted, evaluating CFI, RMSEA, and SRMR indices. Internal consistency was estimated using Cronbach's alpha and McDonald's omega. The initial unidimensional model (16 items) showed acceptable fit (CFI = 0.975; RMSEA = 0.078; SRMR = 0.061), but item 16 presented a very low factor loading (0.050; p = 0.231). After removing it, the 15-item model showed improved fit (CFI = 0.980; RMSEA = 0.055; SRMR = 0.057) and all factor loadings exceeded 0.500, except for item 7 (0.084; p = 0.033), which was retained for theoretical relevance. Internal consistency was high (α = 0.87; ω = 0.88; CR = 0.89; AVE = 0.62). The 15-item TPS-E showed adequate psychometric properties in Ecuadorian university students, being a reliable and valid instrument for assessing academic procrastination in this context. Its use in research and intervention is recommended, and future adaptations should explore convergent validity and potential cultural differences affecting specific items.

The aim of this study was to determine the transplant readiness levels of patients awaiting organ transplantation, to assess the ability of the patient to adjust to life post-transplant, and to conduct a validity and reliability assessment of the organ transplant readiness scale to be able to offer patients the support they require. This Methodological descriptive study was conducted between December 2023 and February 2024 on 227 patients awaiting kidney transplantation. The data were evaluated using IBM SPSS Statistics 23 and IBM SPSS AMOS 23 programs. Descriptive statistics (n, %) were given for categorical variables. In evaluating the scores given by experts, the Content Validity Index (CVI) and Content Validity Rates (CVR) were calculated. The characteristics of the participants were examined with frequency and percentage distributions. Exploratory and confirmatory factor analysis, Cronbach's alpha coefficient and item-total correlation were used to evaluate the data for construct validity. The total Cronbach's alpha coefficient of the Turkish scale was 0.94. From the confirmatory factor analysis, the results of the model-fit index were: RMSEA: 0.099, GFI = 0.829, NFI: 0.886, IFI: 0.919, CFI = 0.918, RFI: 0.85. According to the explanatory and confirmatory factor analysis, 11 items with low factor loads were discarded, and the scale was finalised as 21 items. The Organ Transplant Readiness Scale was determined to have a 5-factor structure: knowledge, treatment compliance, healthy living, cognition, and social support. Test-retest reliability evaluated using intraclass correlation was found to be 0.99. The Turkish version of the Organ Transplant Readiness Scale, prepared for patients waiting for organ transplantation, would be a valid and reliable measurement tool for Turkish society. The findings showed that the Turkish version of the scale consists of 5 subscales, and the Cronbach's alpha value of the scale was high. This scale can determine the needs of patients preparing for organ transplantation and guide nurses in planning the nursing care. Thus, it can give healthcare professionals an idea about how ready patients are for organ transplantation and how patients will be able to adapt after organ transplantation.

PurposeThis study aimed to adapt and assess the validity and reliability of the Spanish version of the Exercise in Eating Disorders Questionnaire (EED-Q) in order to diversify and offer a more comprehensive, effective, and standardized assessment of maladaptive exercise (ME) in ED. MethodsThe EED-Q is a self-reported questionnaire that assesses eating disorders (ED) patients' attitudes towards exercise. Based on the four-factor model of the original version, the EED-Q was adapted through forward and back-translation and inconsistencies were addressed through a committee of experts. Then, the EED-Q Spanish version (S-EED-Q) was administered to 172 patients with eating disorders (age = 15.28 ± 1.64 years). An exploratory factor analysis was computed to assess the construct validity. Inter-item correlations, item-factor correlations, McDonald's Omega, and Cronbach's Alpha were estimated to test the internal consistency (reliability). In addition, convergent validity was tested by relating EED-Q and the Eating Disorders Inventory 2 (EDI-2) scores, discriminant validity was assessed comparing EED-Q item-factor correlations, and divergent validity was conducted by analyzing EED-Q factor correlations. ResultsThe S-EED-Q revealed significant generalized correlations among the scale items and showed good reliability scores (McDonald's Omega and Cronbach's alpha >0.7) except for Factor 2 (McDonald's Omega = 0.63 and Cronbach's alpha = 0.58). After eliminating items 8 and 15 due to their low factor loadings, the EFA revealed a robust empirical factor structure, adequate to the theoretical model, with good levels of total explained variance (65%). Convergent, discriminant and divergent validity showed good performance: results showed expected correlations between EED-Q and EDI-2, all items achieved higher item-factor correlations in their theoretical factor than in the others, and all factor-factor correlations were as expected. ConclusionThis study is the first to adapt and validate the S-EED-Q. The psychometric properties of the S-EED-Q compared to the original version were supported with some limitations. Although the psychometric properties of the scale are adequate and the construct, convergent, discriminant and divergent validity are endorsed, some of the original items are questionable. Likewise, the items of the positive and healthy exercise factor require an in-depth revision.

Introducción. En comparación con la polisomnografía (PSG), la escala de somnolencia de Epworth (ESE) tiene propiedades clinimétricas limitadas, por tanto es necesario revisar su estructura factorial.Objetivo. Revisar la estructura factorial (dimensionalidad) y la consistencia interna de la ESE en un grupo de pacientes a los que se les realizó PSG en Santa Marta, Colombia.Materiales y métodos. Se realizó una investigación para medir las propiedades clinimétricas de la ESE. La muestra estuvo compuesta por 684 adultos entre 18 y 64 años (media=43.2, desviación estándar=13.4) que habían completado los 8 ítems de dicha escala. 440 eran hombres y 244, mujeres. Para probar la estructura factorial se usó el análisis factorial confirmatorio (AFC) y para computar la consistencia interna, los coeficientes omega de McDonald y alfa de Cronbach.Resultados. La estructura de factores fue unidimensional y explicó el 42% de la varianza. En cuanto al AFC, los coeficientes de bondad de ajuste fueron insatisfactorios: χ²=146.47 (gl=20, p=0.001), RMSEA=0.096 (IC90%: 0.082-0.111), CFI=0.902, TLI=0.863 y SMSR=0.047. Los coeficientes omega de McDonald y alfa de Cronbach fueron ambos de 0.80 (IC95%: 0.78-0.82).Conclusiones. La ESE presentó una estructura unidimensional limitada, por lo que es necesario revisar el constructo de somnolencia excesiva o refinar su estructura factorial, pues es posible que con ello se obtengan mejores indicadores en comparación con el mejor criterio de referencia para diagnosticar somnolencia diurna excesiva.

Artificial intelligence (AI) has recently entered the medical field, but the level of readiness of medical students for it is not obvious. A tool with appropriate psychometric properties for use in different languages and for international comparison is required to measure this readiness. Medical Artificial Intelligence Readiness Scale for medical students (MAIRS-MS) is most complete scale for this purpose till now. The purpose was to evaluate the Psychometric properties of the Persian-translated version of the MAIRS-MS and verify the replication of the original factor structure in Persian. This study was conducted at Guilan University of Medical Sciences in 2023. Validation of the Persian translated scale (P-MAIRS-MS) was performed by determining the face, content, and construct validity and reliability, impact Score, CVI, CVR, Cronbach's alpha, McDonald's omega, and ICC, and performing confirmatory factor analysis (CFA). AMOS26 and SPSS26 software were used. The translated scale had good quantitative and qualitative face and content validity (all items had the Impact Score higher than 1.5, CVI >= 0.8 and CVR>= 0.8). CFA confirmed the appropriate fit of the four-factor model (χ2/df = 1.963, RMSEA-0.063, CFI = 0.939, GFI = 0.901). Convergent validity was suitable in the first- and second-order CFA (AVE > 0.5, CR > 0.7 CR > AVE for each factor except Ability). Cronbach's alpha (α=0.938) and McDonald's omega (ω= 0.938), and ICC (0.992) indicated acceptable reliability and reproducibility of the scale. The P-MAIRS-MS demonstrated good psychometric properties and can be used for measuring and international comparing the medical students' readiness for AI.

Self-Efficacy scale for teachers. The items of the scale were prepared as a result of examining the literature on self-efficacy and project-making. In the first stage, the scale, which contains 40 items, was applied to a total of 578 teachers working in different branches in 7 geographical regions of Türkiye. The collected data were used to perform exploratory factor analysis (N=199) and confirmatory factor analysis (N=379). As a result of the exploratory factor analysis, it was determined that the scale, which was reduced to 19 items, had a 3-factor structure (project topic selection guidance, project implementation guidance, and project reporting guidance). The confirmatory factor analysis showed a good fit of the 19-item three-factor structure. The results revealed Cronbach's Alpha coefficient (α=.96) and McDonald's Omega (ω=.96) in the exploratory factor analysis data set, indicating a good internal consistency for the overall scale; and Cronbach's Alpha coefficient (α=.95.) and McDonald's Omega (ω=.95) in the confirmatory factor analysis data set, reflecting an excellent internal consistency. The results of the study show that the developed project guidance self-efficacy scale has good psychometric properties and reliability to measure teachers' self-efficacy for project guidance.

BackgroundReasonable instruction and promotion of appropriate exercise are crucial to improving the exercise status of pregnant women and safeguarding the health of both mother and fetus. However, there is a lack of validated Pregnancy Exercise Attitude Scales with a complete evaluation system in China. This study aims to assess the validity and reliability of the Pregnancy Exercise Attitude Scale (C-PEAS) in Chinese to give medical professionals a reference for carrying out pregnancy care services and promoting the health of the mother and fetus.MethodsIn this study, the scale was translated, back-translated, and cross-culturally adapted using the Brislin translation model to form the C-PEAS. 528 pregnant women were conveniently selected for the questionnaire survey to evaluate the scale's reliability. The scale's content validity was assessed by the content validity index, while its structural validity was investigated using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Cronbach's alpha coefficient, McDonald's omega coefficient, split-half reliability, and retest reliability were used to evaluate the scale's internal consistency.ResultsThe C-PEAS contains two dimensions with 37 entries. The EFA supports a two-factor structure with a cumulative variance contribution of 62.927%. The CFA model was well fitted (χ2/df = 1.597, RMSEA = 0.048, IFI = 0.955, TLI = 0.952, and CFI = 0.955). The C- PEAS' Cronbach's alpha coefficient was 0.973, and the range of Cronbach's alpha values for the dimensions was 0.976, 0.944. McDonald's omega coefficient was 0.971, the half-point reliability of the scale was 0.856, and the retest reliability was 0.966.ConclusionsThe Chinese version of C-PEAS has good psychometric properties. It can be used as an effective measurement tool to evaluate the attitude of pregnant women to exercise during pregnancy.

AimTo evaluate the psychometric properties of the Post-Stroke Depression Scale in the Sequelae Stage (PSDS-SS).BackgroundThe incidence of the sequelae stage Post-Stroke Depression (PSD) is high, and the best screening tools are still lacking. Under this circumstances, our research team developed the PSDS-SS by Delphi method, but its psychometric properties need to be further verified.MethodThis was a cross-sectional study. Seven hundred and sixteen stroke patients in the sequelae stage were enrolled by purpose sampling from May 2022 to September 2022. The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to verify the factor structure of the scale. The reliability of the scale was tested by Cronbach’s α coefficient, test–retest reliability and composite reliability. The validity of the scale was tested by criterion-related validity, convergent and discriminant validity.ResultEight items were deleted through item analysis. The EFA ended up with a 5-factor scale including 24 items after removing one item with low factor loading. Finally, a 21-item model was established by confirmatory factor analysis, and all the fit indexes were acceptable. The reliability and validity of the total scale and each factor are acceptable.ConclusionThe PSDS-SS has a stable factor structure, and demonstrated good reliability and validity. And it would be an effective tool to assess PSD in the sequelae stage.

COVID-19 pandemic causes drastic changes in workplaces that are likely to increase quite quitting among employees. Although quiet quitting is not a new phenomenon, there is no instrument to measure it. To develop and validate an instrument assessing quiet quitting among employees. We identified and generated items through an extensive literature review and interviews with employees. We carried out the content validity by content experts and we calculated the content validity ratio. We checked face validity by conducting cognitive interviews with employees and calculating the item-level face validity index. We conducted exploratory and confirmatory factor analysis to investigate the quiet quitting scale (QQS) factorial structure. We checked the concurrent validity of the QQS using four other scales, i.e., Copenhagen burnout inventory (CBI), single item burnout (SIB) measure, job satisfaction survey (JSS) and a single item to measure turnover intention. We estimated the reliability of the QQS measuring Cronbach's alpha, McDonald's omega, Cohen's kappa and intraclass correlation coefficient. After expert panel review and item analysis, nine items with acceptable corrected item-total correlations, inter-item correlations, floor and ceiling effects, skewness and kurtosis were retained. Exploratory factor analysis extracted three factors, namely detachment, lack of initiative and lack of motivation, with a total of nine items. Confirmatory factor analysis confirmed this factorial structure for QQS. We found statistically significant correlations between QQS and CBI, SIB, JSS and turnover intention confirming that the concurrent validity of the QQS was great. Cronbach's alpha and McDonald's omega of the QQS were 0.803 and 0.806 respectively. QQS, a three-factor nine-item scale, has robust psychometric properties. QQS is an easy-to-administer, brief, reliable and valid tool to measure employees' quiet quitting. We recommend the use of the QQS in different societies and cultures to assess the validity of the instrument.

Cross-cultural adaptation and psychometric validation of an Arabic version of the 12-item Zarit burden interview.

Suicide resilience has garnered increasing attention from researchers due to its potential role in suicide prevention. In 2021, Sánchez-Teruel etal. developed a tool to assess the resilience levels of individuals with a history of suicide attempts. The Scale of Resilience to Suicide Attempts (SRSA) is composed of 18 items across three dimensions: internal protection, emotional stability, and external protection. While the scale has shown robust psychometric properties in Spanish-speaking populations, cultural differences call for a revalidation of its psychometric characteristics among suicide attempters in Mainland China. This study aims to translate and adapt the SRSA into Chinese, and to evaluate its psychometric properties in adolescents who have attempted suicide in Mainland China. Following Brislin's translation model, a survey was conducted using purposive sampling on 393 adolescents who had attempted suicide at the Hangzhou Normal University Affiliated Hospital and the Affiliated Mental Health Center of Zhejiang University School of Medicine. An expert panel evaluated the content validity. The scale's structural validity was assessed through exploratory factor analysis and confirmatory factor analysis, along with measurement invariance. Additionally, tests for convergent validity, discriminant validity, and criterion-related validity were conducted. Reliability was evaluated using Cronbach's alpha coefficient, McDonald's omega, test-retest reliability, and split-half reliability. The Chinese version of the SRSA comprises three dimensions and 16 items. The item-level content validity index for all items ranged from 0.88 to 1.00, while the Scale-Level Content Validity Index was 0.97. The three common factors explained a cumulative variance of 59.339%. Confirmatory factor analysis demonstrated a good model fit. The Cronbach's alpha coefficient for the entire scale was 0.908, and McDonald's omega was 0.910, with individual dimension Cronbach's alpha values ranging from 0.780 to 0.869 and McDonald's omega ranging from 0.859 to 0.910. The Chinese version of the SRSA is a valid and reliable tool for assessing the resilience levels of adolescents who have attempted suicide in Mainland China.

This study was conducted to examine the validity and reliability of the Turkish version of the Public Stigma of Stroke Scale (PSSS). The stigma perceived by patients who have had stroke affects the quality of life as well as many health-related factors. Therefore, it is necessary to determine the society's stigmatization of the stroke patient and to reveal the differences related to stroke in different cultures. This study is methodological research. This study was conducted with 410 individuals aged 18 and over. The data were collected by using descriptive information form and PSSS. The data were evaluated by using exploratory and confirmatory factor analysis, Cronbach's alpha, McDonald's Omega reliability, composite reliability, mean variance extracted and test-retest analysis. Factor load values of the scale items were found to vary between 0.585 and 0.904. The fit index values in the scale were found as X2/df = 2.42, < 0.001, CFI = 0.934, TLI = 0.928, SRMR = 0.042 and RMSEA = 0.059. It was found that Cronbach's alpha coefficients of the factors of the scale ranged between 0.916 and 0.946, and the total Cronbach's alpha coefficient was 0.897. Total McDonald's omega coefficient was found to be 0.897, and McDonald's omega coefficients of the factors were found to be between 0.921 and 0.951. Total composite reliability was found to be 0.981, and total mean variance extracted was found to be 0.740. It was found that the Turkish version of the 33-item and four-factor scales was confirmed without any changes in the original scale form. Turkish version of PSSS is a valid and reliable measurement tool for the evaluation of the stigmatization of stroke patients by the public and for use in clinical practice.

Loneliness has a significant impact on mental and physical health across different stages of development, with particularly evident effects during adolescence. During this period, young individuals undergo substantial social and emotional transformations, making loneliness a global concern. This study aimed to analyze the psychometric properties of the UCLA-R Loneliness Scale in Ecuadorian adolescents through exploratory and confirmatory factor analysis, assess its internal consistency, and examine factorial invariance across genders. The sample consisted of 718 school-aged adolescents (288 males and 430 females) aged 14-17 years (M = 15.72, SD = 0.747), selected through probabilistic sampling. A sociodemographic ad hoc questionnaire and the Spanish version of the 20-item UCLA-R Loneliness Scale were administered. The sample was randomly divided into two equivalent subsamples (n = 359) to separately perform an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA). The EFA was conducted using principal axis factoring, oblique rotation, and polychoric correlations. The CFA evaluated one-factor, two-factor, and three-factor models, employing fit indices such as CFI, TLI, RMSEA, and SRMR. Internal consistency was estimated using Cronbach's alpha and McDonald's omega coefficients. Additionally, factorial invariance analyses by gender were performed, along with a univariate ANOVA to examine potential gender differences. The exploratory factor analysis (EFA) results indicated the presence of two factors, whose structure explains 40.8% of the total variance, with 19 items. The confirmatory factor analysis (CFA) confirmed that the bifactor model with 19 items exhibited a superior fit compared to the unidimensional and three-factor models with 20 items, with fit indices falling within acceptable to excellent ranges (CFI = .936, TLI = .927, RMSEA = .050, SRMR = .048). Additionally, the bifactor model demonstrated measurement invariance across genders. Regarding internal consistency, the scale demonstrated a Cronbach's alpha of.876 and an omega coefficient of.83, confirming its reliability. It is concluded that the 19-item UCLA-R Loneliness Scale is a valid and reliable instrument for assessing perceived loneliness in Ecuadorian adolescents, regardless of gender. Future research could replicate these findings in other regions and cultural contexts to validate its use on a larger scale.
