McDonald's Omega Coefficient Research Articles

Resumen.Las estrategias conductuales de regulación emocional en adolescentes han demostrado estar asociadas a problemas de salud mental como la depresión, siendo importante contar con instrumentos que permitan su evaluación. Este estudio es de diseño instrumental y tiene como objetivo evaluar las propiedades psicométricas del Behavioral Emotion Regulation Questionnaire (BERQ) en adolescentes peruanos. La muestra se seleccionó mediante muestreo no probabilístico por conveniencia y estuvo conformada por 392 adolescentes entre 14 y 17 años (M = 15.75; DE = .85) donde el 52.5% fueron hombres. Mediante un modelamiento exploratorio de ecuaciones estructurales se obtuvo que la estructura original de cinco factores se replica (CFI = .988; RMSEA = .045, IC90% .031,.058; WRMR = .429) y cada uno obtuvo valores de confiabilidad aceptables mediante los coeficientes Alfa de Cronbach y Omega de McDonald. Además, se encontró que solo retirada (β = −.49), enfrentar activamente (β = −.21) e ignorar el problema (β = .24) son predictores estadísticamente significativos de la depresión. Se concluye que el instrumento puede ser utilizado en investigaciones y como apoyo de los profesionales en la evaluación del constructo.

Background & Aim: Emergency nurses face unique stressors that increase their occupational stress. Most existing tools measure general stress and overlook emergency-specific factors. This study aimed to assess the psychometric properties of the Persian version of the Stressor Scale for Emergency Nurses. Methods & Materials: This is a cross-sectional study that used the forward-backward method to translate the tool from English to Persian. Face and content validity were assessed by five emergency nurses and five nursing faculty members, respectively. Construct, known-group, and convergent validity were tested in 198 emergency nurses from Saqqez and Sanandaj hospitals (2024). Test-retest reliability was evaluated in 21 nurses over two weeks. Internal consistency was measured using Cronbach’s alpha and McDonald’s omega. Data were analyzed using Jamovi 2.4.14. Results: Face and content validity were satisfactory. Exploratory factor analysis identified four factors—conflicts, life and death situations, patients' families' actions and reactions, and technical/formal supports, which explained 60.64% of total variance. Convergent validity showed a correlation of 0.554 between job stress scores based on the Stressor Scale for Emergency Nurses and the Brief Nursing Stress Scale. Known group validity revealed that occupational stress scores were higher in women than men, and there was a significant negative correlation between occupational stress and work experience in the emergency department. Cronbach's alpha and McDonald's omega coefficients were 0.953 and 0.954, respectively; the intraclass correlation coefficient was 0.943. Conclusion: The Persian version of the stressor scale shows strong psychometric properties and is reliable for assessing occupational stress in emergency nurses.

Objective: To Determine the validity and reliability of the Scoliosis Research Society Questionnaire (SRS-22) in Peruvian adolescents with idiopathic scoliosis in a national rehabilitation institute. Materials and methods: Seventy-three adolescents affected by idiopathic scoliosis between 10 and 17 years of age [13.6±1.8), collected through non-probability sampling, were evaluated. Validity based on internal structure was reported through confirmatory factor analysis; reliability by means of Cronbach's Alpha and McDonald's Omega coefficient; and validity based on the relationship with other variables was tested between the SRS-22 with the Short Form Survey Questionnaire (SF-36) and QoL Profile for Spine Deformities (QLPSD). Results: The original model [SRS-22) was found to have adequate evidence of factorial validity with better fit indices (X2 /gL=1.36, CFI=0.962, TLI=0.956, RMSEA=0.07 [0.047-0.091], SRMR=0.122) compared to the short models [SRS-16 and SRS-7). The reliability of the original model was satisfactory for each of the factors, with values above 0.70. Regarding validity based on the relationship with other variables, direct significant relationships were identified between the SRS-22 and SF-36 and QLPSD. Conclusions: The SRS-22 has adequate evidence of validity and reliability for the sample evaluated, requiring further revision of the short versions.

The Social Attribution Task-Multiple Choice (SAT-MC) battery is one of tests used to evaluate social cognitive capacity. This study aimed to examine the reliability and validity of the SAT-MC for the first time in healthy adults and in individuals diagnosed with schizophrenia, then to investigate the effect on SAT-MC performance of clinical variables in schizophrenia patients. The study included 207 volunteers; 157 healthy adults, and 50 individuals diagnosed with schizophrenia. All the study participants were applied with the Raven Standard Progressive Matrices Test (RSPM), the Reading the Mind in the Eyes Test (RMET), and the SAT-MC. The results of the analyses showed that the SAT-MC had content and criteria validity in both the individuals diagnosed with schizophrenia and in the healthy control group. Internal consistency of test was calculated as McDonald's omega coefficient 0.81, and the test-retest reliability was found to be 0.75. Hierarchical multivariate regression analysis showed a predictive effect of RSPM and RMET on the SAT points. The results of this study demonstrated that SAT was valid and reliable in evaluating social attribution skills in both a healthy and a schizophrenia sample group. Social attribution skill was found to be related to the perceptual reasoning and abstract thinking skills of neurocognition. The social cognition dimension was determined to be related to the theory of mind skills. Insufficient social attribution skills, seen especially in schizophrenia patients, can lead to social withdrawal and isolation by disrupting interactions and relationships with others.

In this research, it was aimed to develop a valid and reliable measurement tool to determine the brain rot levels of individuals. The research study group was formed by selecting among the Alpha generation individuals who are accepted to use social media more intensively. In the scale development process, draft scale development, EFA, CFA, test-retest, and known group validity methods were used. Cronbach's Alpha and McDonald's Omega coefficients were calculated for the reliability analyses of the scale. According to the findings obtained as a result of the analyses, the scale consists of four dimensions and 18 items. The scale dimensions are cognitive load, cognitive fatigue, emulation, and depersonalization. The fit indices of the structure obtained with CFA are acceptable and good fit level. Cronbach's Alpha and McDonald's Omega coefficients calculated for the reliability of the scale are above 0.70. According to the methods of test-retest and known group validity methods, the developed scale makes measurements that are stable and can distinguish different groups. As a result of all analyses, it was determined that the developed brain rot scale is a valid and reliable measurement tool.

Introduction: It is essential to use valid and reliable tools in evaluating nurses' sexual health care practices. This study aims to develop a valid and reliable Sexual Health Care Practices Evaluation Scale (SHCPES) to be used in evaluating the sexual healthcare practices of nurses. Method: Cross-sectional and methodological research methods were used in the research. The research sample consisted of 309 nurses working in hospitals in Turkey's Central Black Sea Region. The results of quantitative and qualitative studies in the relevant literature were used to create the scale item pool. Expert opinion was taken to test the validity of the content. Content validity and factor analysis were used to determine the scale's validity, two-half test reliability was used to determine its reliability, and the Cronbach Alpha reliability coefficient was calculated. Results: According to the exploratory factor analysis results of the scale, the Kaiser-Meyer-Olkin test value was found to be 0.98, Bartlett test χ2 = 13275.67, df = 703, p <.000. After removing items with factor loading values below 0.40 from the scale, the factor structure obtained explained 68.71% of the total variance. According to the confirmatory factor analysis results, χ2 =.000, CMIN/DF = 2.74, RMSEA = 0.07, GFI = 0.79, NFI = 0.90, TLI = 0.92, and CFI = 0.93. . CSBU-SS consists of two sub-dimensions titled "Initiating and Maintaining Communication" and "Sexual Health Care Practices" and 30 items. In all subscales of the scale, Cronbach Alpha values were found to be 0.98 for the overall scale, 0.96, and 0.94 for the subgroups. McDonald's Omega Coefficient was used to show that the scale's internal consistency was strong, and similar results were obtained. McDonald's Omega Coefficient values were 0.98 for the overall scale and 0.98–0.94 for the subgroups. Split test reliability was calculated with the Spearman-Brown formula after dividing the scale into two equivalent halves, and the result was found to be 0.98. Conclusion: The study determined that CSBU-DS is a valid and reliable measurement tool in determining nurses' sexual health care practices. It is recommended that the psychometric structure of the scale be evaluated in more comprehensive studies on different samples.

The sustainable training of higher education teachers at a Sinaloa university is analyzed, in its academic units in the north of the State. The objective was to identify areas of opportunity in such training, so that HEIs have information that allows them to empower teachers as agents of change in sustainable matters. The approach of the study was quantitative, descriptive-transversal, applying a Likert-type instrument through the Google Forms platform to 239 teachers from a universe of 488 that make up the study area in 7 academic units (see table 2). The instrument was subjected to internal consistency measurement using McDonald's Omega coefficient, yielding an adequate value of W=0.874. The findings show that there are challenges for the educational institution and the teachers themselves in aspects of training, better self-management and programs that strengthen sustainable training are required, so the SDGs and the 2030 Agenda can help improve the situation. Research is recommended that supports what this study postulates, as well as institutional and personal initiatives on leadership issues that promote the proper role of the actors involved.

Introduction: Suicidal ideation is an understudied issue during the gestational period, requiring valid and reliable instruments for timely measurement and to provide support in perinatal mental health. However, there are limited scales available to assess suicidal ideation in pregnant women in Colombia.Objective: To explore the dimensionality and internal consistency of the Roberts’ scale for suicidal ideation in pregnant women from Santa Marta, Colombia.Methods: 172 pregnant women between 18 and 44 years of age (M=24.7; SD=5.49) completed the Roberts suicidal ideation scale. An exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out to determine dimensionality and Cronbach's alpha and McDonald's omega coefficients were calculated to establish internal consistency.Results: In the CFA the Roberts’ scale indicated a unidimensional internal structure explaining 50.5% of the variance and with adequate goodness-of-fit indicators (X2=5.85, gl=2, p<0.054; RMSEA=0.104 (CI90%=0.000-0.210); SRMR=0.025; CFI=0.981; TLI=0.944). Cronbach's alpha coefficient was 0.781 and McDonald's omega coefficient was 0.801, showing acceptable internal consistency.Conclusions: Roberts’ scale is a brief, reliable measure with strong validity evidence for assessing suicidal ideation in pregnant women. Further instrumental studies with a larger sample size are recommended to corroborate the psychometric performance of the instrument in the Colombian population.

Measurement of the quality of mother-infant feeding interactions across the first year: Reliability and stability of the parent-child early relational assessment.

Unesp-Botucatu sheep acute pain scale (USAPS) was validated for assessing postoperative abdominal pain. We aimed to investigate the clinical applicability and test the psychometric properties of USAPS to assess postoperative pain in sheep submitted to orthopedic surgery. Twenty-three healthy sheep undergoing patellofemoral joint arthrotomy were video-recorded for three minutes before and after surgery, after postoperative analgesic rescue, and 24 hours post-surgery. Four evaluators, unaware of the recording time points, randomly assessed all videos twice at one-month intervals. Intra-observer reliability based on the Intraclass Correlation Coefficient (ICC) was very good for all evaluators (ICC: 0.82-0.93). Inter-observer reliability was very good for four of six pairs of evaluators (ICC: 0.84-0.9) and good for two (ICC: 0.77 and 0.80). Principal component analyses and confirmatory factor analysis confirmed the USAPS´s unidimensional structure. The concurrent criterion validity had a strong Spearman correlation (rho: 0.80) between the USAPS and the Visual Analogue Scale. Responsiveness was evidenced by the highest USAPS total score 2 and 24 hours after surgery, and intermediate scores after analgesic rescue. USAPS items had an acceptable Spearman item-total correlation (rho: 0.38-0.64), except appetite (rho: 0.25). Internal consistency was excellent according to Cronbach's alpha (α: 0.84) and acceptable according to McDonald's omega coefficients (ω: 0.75). Specificity was 100% and sensitivity was 71%. USAPS cut-off point was ≥ 4 of 10, the same applied for soft tissue surgery. The area under the curve of 0.91 demonstrates the high discriminatory capacity of the scale. The item appetite can be excluded without affecting the USAPS cut-off point. We concluded that USAPS had satisfactory psychometric properties and, is a valid and reliable clinical tool for assessing pain in sheep undergoing orthopedic surgery.

BackgroundEducational leadership plays a crucial role in the development of nursing students, significantly enhancing their clinical skills and preparing them to lead advancements in healthcare. This comprehensive educational approach ensures that nursing students are well-equipped to address contemporary healthcare challenges effectively.AimThis study aimed to translate the Educational Leadership Scale for Nursing Students into Persian and evaluate its psychometric properties among Iranian nursing students.MethodsThis cross-sectional methodological study was conducted in two phases: translation and cultural adaptation, followed by psychometric evaluation. After obtaining permission from the original scale developer, the scale was translated into Persian using the Pilot and Yang model. Face and content validity were assessed both qualitatively and quantitatively. Construct validity was evaluated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). A convenience sample of 469 nursing students from nursing faculties in Kermanshah Province, Iran, completed the questionnaire. Internal consistency was evaluated using Cronbach's alpha and McDonald's omega coefficients. Test–retest reliability was assessed using the intraclass correlation coefficient (ICC) in a subsample of 47 nursing students.ResultsExploratory and confirmatory factor analyses confirmed the three-factor structure of the Persian version of the instrument, with 19 items accounting for 63.80% of the total variance. The model fit was excellent, as shown by the CFI, GFI, TLI, RMSEA, and SRMR values. The scale demonstrated acceptable internal consistency reliability, with Cronbach's alpha at 0.924 and McDonald's omega at 0.923. The ICC for the total score was 0.924 (95% CI: 0.910–0.936).ConclusionThe results of the present study indicate that the Persian version of the Educational Leadership Scale for Nursing Students possesses acceptable psychometric properties. The results of face, content, and construct validity, along with reliability indices (including internal consistency and test–retest reliability), indicate that this instrument is an effective tool for evaluating educational leadership characteristics among Iranian nursing students. However, to further confirm the validity and reliability of this scale, future studies with larger and more diverse samples of nursing students, including those in clinical settings, are recommended. Furthermore, examining the criterion validity and discriminant validity of this instrument could contribute to a better understanding of its psychometric characteristics.

Background/Objectives: The complexity of modern healthcare requires teamwork. Healthcare teams must be cohesive to ensure efficient and quality care. The objective of this study was to validate the Spanish short version of the Group Environment Questionnaire (GEQ) in undergraduate nursing students undergoing clinical simulation training. Methods: The psychometric properties of the questionnaire were analyzed. We began with a statistical analysis of the items. Internal consistency was assessed using McDonald's omega coefficient. Test-retest reliability was determined using Spearman's correlation coefficient. An exploratory factor analysis was performed using the principal components analysis method with varimax rotation. Finally, a confirmatory factor analysis of the proposed theoretical models was performed to select the most appropriate one using the weighted least squares method adjusted for mean and variance (WLSMV) and goodness-of-fit indices. Results: The questionnaire items showed a standard deviation higher than 1 and a negative skewness lower than 0.5. Internal consistency and test-retest reliability were higher than 0.8. The item-total correlation coefficient values were above 0.44. The exploratory factor analysis confirmed the presence of four factors, each with three items. Confirmatory factor analysis determined that the four-factor cohesion model was the one that obtained the best fit. Conclusions: The Spanish short version of the Group Environment Questionnaire (GEQ) is a valid and reliable instrument for analyzing group cohesion in teams of nursing students undergoing clinical simulation training.

ABSTRACTBackground and AimsExisting tools for measuring ethical competence in nursing students have limitations, often failing to comprehensively assess the general concept and are frequently developed for practicing nurses, limiting their applicability to students. This study aimed to develop and psychometrically evaluate an ethical competence tool specifically designed for nursing students.MethodThis methodological study employed an instrument‐development approach. The process involved developing an ethical competence measure for nursing students followed by a thorough psychometric evaluation. The tool's psychometric properties were assessed using face, content, and construct validity, as well as reliability through internal consistency and stability methods. Statistical analyses were conducted using SPSS version 27, JASP version 0.14, Microsoft Excel 2007, and Amos 25.ResultsA 26‐item tool with two dimensions—“commitment to professional ethics and humanistic care” (19 items) and “interaction and cooperation in the clinical environment” (7 items)—was developed. The tool demonstrated excellent psychometric properties, explaining 68.427% of the total variance. Individual item factor loadings ranged from 0.549 to 0.875. Cronbach's alpha and McDonald's omega coefficients for the total scale were 0.883 and 0.898, respectively, indicating high internal consistency. Test‐retest reliability also yielded strong results, with the intracluster correlation coefficient calculated at 0.998 (95% CI: 0.995‐0.999). The tool effectively captures key components of ethical competence in nursing students.ConclusionThe newly developed tool provides a reliable and valid measure of ethical competence in nursing students. This study offers educational managers in the healthcare field a valuable resource for designing a system to assess ethical competence among Iranian nursing students.

Smartphone addiction is very prevalent among university students and can negatively impact both their physical and mental health. This study aimed to translate the smartphone application-based addiction scale (SABAS) into Spanish and evaluate its psychometric properties among Spanish university students. A total of 297 university students (222 women and 75 men) participated in this study (M age = 20.88, SD = 4.58) by completing a sociodemographic questionnaire, the smartphone addiction scale-short version, the depression, anxiety, and stress scale-21, the fear of missing out scale, and the SABAS. The SABAS was translated into Spanish using the forward-backward method. The factor structure was analyzed using confirmatory factor analysis, while reliability was assessed with Cronbach's alpha and McDonald's omega coefficients. The SABAS showed acceptable reliability (α = 0.72; ω = 0.73), and all of its items were kept. Factor analysis revealed that the Spanish version of the SABAS was unifactorial and demonstrated excellent validity (χ2 = 10.285; p = 0.246; RMSEA = 0.034; CFI = 0.991; SRMR = 0.030). Significant associations were also observed between the SABAS score and the number of hours of smartphone use, fear of missing out, and psychological distress. Despite its brevity, the Spanish version of the SABAS provides good validity and reliability. Therefore, it can be used as a tool for screening smartphone addiction in Spanish university students.

The High Five Inventory (HFI) was developed to assess five positive personality traits: erudition, peace, joviality, honesty, and tenacity. Research on positive personality dimensions remains limited, emphasizing the importance of validating assessment tools in different cultural contexts. This study aimed to analyze the psychometric properties of the High Five Inventory (HFI) in a sample of Ecuadorian university students. An instrumental study was conducted to evaluate the construct validity and reliability of the HFI. A confirmatory factor analysis (CFA) was performed to assess the inventory's factorial structure. The sample consisted of 1,007 students (403 women, 39.9%) from various faculties at Salesiana Polytechnic University in Ecuador. Prior to data collection, a linguistic review was carried out by a panel of experts, including faculty members, researchers, and students, to ensure clarity and comprehension of the items. The final version of the inventory was administered after obtaining informed consent. The CFA results indicated an adequate model fit: χ2 (220) = 859.969, p < 0.001, robust CFI = 0.989, RMSEA = 0.054 (90% CI: 0.050-0.058), and SRMR = 0.045. Additionally, internal consistency was confirmed with Cronbach's Alpha (α) and McDonald's Omega (ω) coefficients ≥ 0.80, demonstrating strong reliability. The findings confirm that the High Five Inventory-Ecuador (HFI-E) exhibits robust psychometric properties, supporting its use in assessing positive personality traits within the Ecuadorian population. The study highlights the relevance of validating personality assessments across different cultural contexts and underscores the potential applications of the HFI-E in psychological and educational settings.

Rasch Analysis Of The Dermatology Life Quality Index

Employed households experience time poverty, which refers to feeling overwhelmed because of the struggle to balance work and life. Time poverty is subjectively perceived as a lack of personal free time. In Japan, long working hours and societal expectations regarding the division of work and family roles may influence the perception of time poverty. This issue is of significant concern, as it can impact individuals' rest time and work productivity. However, there is currently no standardized measurement method to assess time poverty appropriately in the Japanese context. The lack of such a method challenges establishing a foundation for developing effective support strategies. Given this background, this study aimed to quantify time poverty among employed households by developing a Japanese version of the Perceived Time Poverty Scale and examining its reliability and validity. In developing the Japanese version of the Perceived Time Poverty Scale, cultural adaptations were made in addition to the standard translation and back-translation procedures. Through discussions with researchers and translation experts, terms with differing scopes of interpretation in the Japanese context were revised, and expressions were adjusted to reflect the intended concepts better. The data for this study were collected through Wave 2 of the longitudinal survey, the Hama Study, conducted over a five-year period from 2022 to 2027. This survey randomly selected 10,000 employed households residing in Yokohama, Japan. Participants completed the Japanese version of the Perceived Time Poverty Scale developed in this study, along with the well-being scale, the Kessler Screening Scale for Psychological Distress, and the Japanese Short-Form UCLA Loneliness Scale. Exploratory and confirmatory factor analyses were conducted to evaluate the scale structure. Internal consistency was assessed using Cronbach's alpha and McDonald's omega coefficients. Furthermore, correlations between the Japanese version of the Perceived Time Poverty Scale and the other scales were examined to evaluate the structural validity of the scale. Data from 1,979 respondents who participated in the Wave 2 online survey were analyzed. The scale demonstrated high reliability, with a Cronbach's alpha coefficient 0.90 (95% CI: 0.89-0.91). Exploratory factor analysis confirmed a single-factor structure and confirmatory factor analysis supported this structure with fit indexes (CFI = 0.957, TLI = 0.929, RMSEA = 0.136, SRMR = 0.035). Perceived time poverty was negatively correlated with sleep time and leisure time, and positively correlated with childcare time. Furthermore, perceived time poverty showed significant correlations with well-being, psychological distress, social isolation, and job satisfaction, confirming the validity of the developed scale. The Japanese version of the Perceived Time Poverty Scale is a reliable tool with a certain degree of validity for assessing time poverty in Japan. This scale enables individuals and households to recognize time poverty as a modern form of poverty. Furthermore, businesses and local governments can utilize it as an indicator in practical settings, such as improving work environments, implementing childcare support programs, and promoting community health. Future longitudinal studies are needed to further validate the scale, including addressing issues related to model fit.
