McDonald's Omega Coefficient Research Articles

This study aimed to develop and validate an instrument to assess dentists' adherence to infection control protocols and explore psychological factors related to infectious diseases in dental practice. The instrument was developed through phases including context validity, face and semantic analysis, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Internal consistency was evaluated using McDonald's Omega coefficient (ω) and Cronbach's Alpha (α). A total of 405 individuals completed the instrument. EFA (n = 135) revealed a four-factor structure (Work Environmental Protection, Disinfection, Team Training, and Fear and Anxiety) with 23 items with factor loadings above 0.60. The Kaiser-Meyer-Olkin (KMO) value was 0.803, and Bartlett's test of sphericity was significant (χ2: 2501.136, df:253.000, p < 0.001). CFA (n = 270) confirmed an acceptable model fit: χ2/df: 1.75; Comparative Fit Index (CFI): 0.997; Tucker-Lewis Index (TLI): 0.996; Standardized Root Mean Square Residual (SRMR): 0.079; Root Mean Square Error of Approximation (RMSEA): 0.053, supporting the four-factor structure from the EFA. Reliability analysis demonstrated strong internal consistency across all factors (ω and α ≥ 0.70). The developed instrument exhibited appropriate validity, reliability, and internal consistency, providing a suitable tool to evaluate infection control adherence and psychological aspects among dentists facing infectious diseases.

In accordance with the two-way integration requirements of Chinese professional degree training and resident standardization training, we have gradually established a competency comprehensive assessment system (CAS) for professional postgraduate education since 2015. In this study, we aimed to evaluate the scientific and practicality of CAS through a Delphi study. There were two parts in CAS such as dissertation of clinical study and oral clinical proficiency assessment, which including formative assessment and summative assessment. A Delphi questionnaire was scheduled to assess the acceptance about two parts of CAS. Through two rounds of questioning, forty experts were invited to score for each item according to Likert-scale. The scores were analyzed and comments were conducted. The questionnaire responses rate of two rounds were 85% and 97.1%, respectively. The reliability of the results was high with Cronbach's alpha more than 0.8 and the McDonald's omega coefficients more than 0.7. Moreover, most indicators were obtained agreement with high importance mean scores and full-score rates according to the first round. However, the scores of two indicators such as clinical chairside skill examination and patients' satisfaction were relatively low. After second round, the chairside skill examination was suggested being organized after trainees' application, or conducted by the department. The recommended evaluation methods for patients' satisfaction were telephone follow-up by hospital randomly, patients' scores to student immediately, or evaluation by teachers. The CAS integrating research assessment with clinical assessment to evaluate the clinical competency of dental students was acceptable. Most content were highly agreed by experts, indicating the possibility of further promotion.

Challenges during the transition to adulthood affect how adolescents and young adults (AYA) with autism integrate their autism diagnoses into their self-concept. A positive autism identity is crucial for their psychological and social well-being. This study examined the suitability of the Illness Identity Questionnaire (IIQ) for assessing autism identity by assessing its construct validity and internal consistency among 102 autistic AYA (12–25 years). Participants completed the IIQ, which measures four illness identity dimensions: rejection , engulfment , acceptance , and enrichment . We conducted confirmatory factor analysis (CFA) to evaluate the IIQ's factor structure and McDonald's omega coefficients for internal consistency. The CFA demonstrated a good fit between the theoretical model and data, χ²(242) = 257.12, p = .241, comparative-fit index [CFI] = .98, goodness-of-fit index [GFI] = .84, root-mean-square error of approximation [RMSEA] = .02, standardized root-mean-square residual [SRMR] = .09. Internal consistency was high across all dimensions (ω = .85–.90). Acceptance was significantly higher than rejection , engulfment , and enrichment , indicating more adaptive identity integration. The findings support the IIQ as a robust tool for assessing autism identity in AYA. The higher acceptance scores align with previous findings indicating more positive than negative feelings towards autism identity. However, the presence of rejection and engulfment underscores the need to promote more positive perceptions of autism identity. The IIQ offers valuable insights into how autistic AYA integrate their diagnoses into their self-concept. A positive autism identity is essential for improving psychological and social outcomes, making the IIQ valuable for researchers and clinicians.

This study was conducted methodologically to determine the reliability and the validity of the Turkish version of the hemodialysis self-management scale in hemodialysis patients in Turkey. The study was conducted with 200 patients who received hemodialysis treatment between October 2022 and April 2023. Data were collected using a Patient Information Form and the Hemodialysis Self-Management Instrument. To test the reliability of the scale, the internal consistency coefficient Cronbach's Alpha, McDonald Omega, and test-retest reliability coefficients were calculated. Confirmatory factor analysis was performed to evaluate the validity. Unlike the original version, the scale consisted of 11 items and 4 subscales and showed an acceptable fit. The Cronbach alpha coefficient was 0.89; the McDonald Omega coefficient was 0.90. The hemodialysis self-management instrument is a reliable and valid scale in Turkey.

ABSTRACT Findings are reported on initial validation of a Greek translation of the 16-item French adaptation of the Revised Competitive State Anxiety Inventory – 2 (CSAI-2R) capturing self-reported intensity of cognitive anxiety, somatic anxiety, and self-confidence. The sample comprised 402 adult martial arts athletes of Kick Boxing, Muay Thai, Tae Kwon Do, and Jiu Jitsu (257 males, 145 females) aged 18–57 years. CSAI-2R data were collected one hour before competition while performance data were collected up to 30 min. after competition. Confirmatory factor analyses supported the structural validity of the Greek CSAI-2R responses. McDonald's omega coefficients supported subscale internal reliability. Measurement invariance analyses supported item meaning equivalence across males and females, participants with secondary and post-secondary education, athletes who lost or won the match, and athletes who reported having achieved their goal in the match or not. Lower cognitive and somatic anxiety, and higher self-confidence emerged for athletes of the good performance category compared to the poor performance category. Lower cognitive anxiety and higher self-confidence emerged for athletes who won the match, and for athletes who reported achieving their goal in the match. Lower somatic anxiety and higher self-confidence was found for males compared to females. The present findings provide initial psychometric support to the Greek 16-item CSAI-2R scores and extend validity evidence of the CSAI-2R.

This study evaluates the psychometric properties of the Vietnamese version of the Copenhagen Burnout Inventory (CBI-V) and examines factors associated with burnout among community pharmacists in Thua Thien Hue, Vietnam. A cross-sectional, interview-based study was conducted in Hue City from January to June 2023, involving 362 pharmacists. The following measurement properties of CBI-V were tested: distributional characteristics, structural validity (principal component and confirmatory factor analyses), internal consistency reliability (Cronbach's alpha and McDonald's omega), known-groups validity (Mann-Whitney U or Kruskal-Wallis H test). The CBI-V demonstrated good internal consistency, with Cronbach's α and McDonald's Omega coefficients ranging from 0.867 to 0.904. The 19-item, three-factor model showed a good fit, supported by Kaiser-Meyer-Olkin measures. CPs working in hospital retail settings, experiencing higher job satisfaction, and having a better grasp of accurate drug information sources were associated with higher burnout scores (p<0.05). This psychometric assessment study in community pharmacists concludes that the CBI-V is a reliable tool for assessing burnout, providing insights for public health interventions in healthcare digital transformation.

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.

Validity and Reliability of the Korean Version of Supportive Care Needs Survey-Short Form 34 for Patients With Cancer: A Methodological Study.

The prevalence of Generalized Anxiety Disorder (GAD) has increased rapidly, highlighting the importance of its detection using quick tools applicable to men and women from different countries. To analyze the psychometric properties of the Generalized Anxiety Disorder Test (GAD-7) by gender and country in Latin America and the Caribbean (LAC). A cross-sectional e-health study with 12,124 participants from 15 LAC countries (54.32% women, 45.68% men) was conducted, including participants from Argentina (7.3%), Bolivia (6.7%), Colombia (10.3%), Chile (6.9%), Costa Rica (4.9%), El Salvador (5.7%), Ecuador (7.2%), Guatemala (4.7%), Panama (5.1%), Paraguay (5.7%), Peru (8.6%), Puerto Rico (5.8%), the Dominican Republic (6.6%), Uruguay (6.3%), and Venezuela (8.2%). All participants completed the GAD-7 scale digitally. A unidimensional structure of the GAD-7 was confirmed, explaining 70% of the variance. The model fit indices were adequate (RMSEA = 0.062; CFI = 0.997; TLI = 0.995; SRMR = 0.017; p < 0.001), and the factor loadings for each item were satisfactory (> 0.70). Additionally, the factor structure showed measurement invariance between genders and countries, with adequate fit indices at all levels (configural, metric, scalar, and strict), suggesting that the measurements are equivalent in both contexts. Finally, the internal consistency of the GAD-7 was high, with a McDonald's Omega coefficient of 0.91. The GAD-7 exhibits a factor structure that is equivalent across genders and countries, demonstrating its validity and reliability for the rapid detection of GAD symptoms in different countries within the region.

This study aimed to adapt and analyze the psychometric properties of the Exercise Behavior Regulation Questionnaire (BREQ-3) for assessing motivation towards incidental physical activity. An instrumental study in a sample of 346 university students (21.1 ± 2.6 years, and 61.3% women) from various universities in Chile was undertaken. An adaptation of the BREQ-3 was applied, and a confirmatory factor analysis was performed using a robust weighted least squares estimator to assess the construct validity of the scale. Also, the convergent validity was evaluated using the average variance extracted, the discriminant validity using composite reliability, and the internal consistency using Cronbach's alpha (α) and McDonald's omega (ω) coefficients. The six-factor structure of intrinsic motivation (α = 0.96, ω = 0.96), integrated regulation (α = 0.95, ω = 0.95), identified regulation (α = 0.89, ω = 0.90), introjected regulation (α = 0.75, ω = 0.77), external regulation (α = 0.80, ω = 0.83), and amotivation (α = 0.75, ω = 0.79), with acceptable fit indices after eliminating items 8 and 11, was confirmed-χ2/df: 2.196, CFI: 0.99, TLI: 0.99, RMSEA: 0.059 (90% CI; 0.051-0.067). Adaptation of the BREQ-3 appears to be a reliable measure for assessing motivation in the context of incidental physical activity. Its use will contribute to understanding the explanatory mechanisms underlying this behavior.

The Depression Anxiety Stress Scale for Youth (DASS-Y) is a self-report instrument recently developed to evaluate negative emotional states in children and adolescents. However, the Persian version's factor structure and psychometric properties have yet to be investigated in Iranian youth. The study aimed to assess the factor structure and reliability of the Persian DASS-Y in a sample of Iranian children and adolescents. The study recruited 1,277 children and adolescents, 703 (55.1%) being girls and 574 (44.9%) being boys (aged 7-18 years), from schools in Tehran, Iran. Confirmatory factor analysis (CFA) was conducted to evaluate structural validity and test the fit of three-factor models. Internal consistency reliability was examined using Cronbach's alpha and McDonald's omega coefficients for the DASS-Y total and subscale items. Convergent and discriminant validity were also assessed. The CFA results supported the original 3-factor structure of the DASS-Y, consisting of Depression, Anxiety, and Stress subscales in both groups of Iranian children and adolescents. Subsequently, the Pearson correlation coefficient assessed the scale's convergent and discriminant validity, which was relatively appropriate. Also, the DASS-Y's internal consistency reliability was satisfactory. The Persian DASS-Y is a reliable and valid Instrument for measuring depression, anxiety, and stress in Iranian children and adolescents. It can be helpful for both research and clinical work, helping to assess psychological distress in children and adolescents.

To adapt and evaluate the psychometric properties of the SUSESO/ISTAS21 questionnaire for nurses in Spain. Cross-sectional study for the cross-cultural adjustment and psychometric validation of the COPSOQ-ISTAS21 scale. Descriptive analyses were conducted, and data was correlated. A confirmatory factor analysis was performed, thus assessing the reliability and criterion validity. The sample consisted of 2757 Spanish nurses. The exploratory factor analysis identified a 5-factor structure with 15 items, which explained 63.6% of the variance. The factors were named: Support at work; Job satisfaction; Work-related emotional well-being; Job insecurity; and Double presence. The internal consistency of the questionnaire, measured by Cronbach alpha and McDonald omega coefficient, was adequate, with values of 0.764 and 0.741, respectively. The results of the confirmatory factor analysis indicated a good model fit. Three levels of psychosocial risk (low, intermediate, and high) were identified based on percentiles and quartiles of mean scores. The adapted version of the SUSESO/ISTAS21 questionnaire showed reliable psychometric properties in Spanish nurses, making it a valid and robust tool for assessing psychosocial risks in this group.

This study was conducted to culturally adapt the Epilepsy-Related Apathy Scale in Adults with Epilepsy (E-RAS) to Turkish and to assess its psychometric properties in adult epilepsy patients. A total of 172 epilepsy patients receiving care at the Neurology clinic and outpatient clinic of Fırat University Hospital from February to July 2023 were included in this methodological investigation. The E-RAS was translated into Turkish, and its content and construct validity were thoroughly examined. Construct validity was assessed through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Reliability was evaluated through item analyses, internal consistency analysis, composite reliability coefficient, and mean explained variance analysis. The factor loadings of the scale items ranged from 0.66 to 0.89. The fit index values of the scale were X2 = 467.09, df = 245 (p <0.05), X2/df = 1.9, RMSEA = 0.073, CFI = 0.97, RMR = 0.046, SRMR = 0.057, TLI = 0.97, and AIC = 557.09. The Cronbach's alpha coefficients of the sub-dimensions of the scale ranged from 0.880 to 0.992, and the total Cronbach's alpha coefficient was 0.928. The total McDonald's omega coefficient was 0.916, and the McDonald's omega coefficients of the sub-dimensions ranged from 0.880 to 0.947. The Turkish form of the 24-item and 4-sub-dimensional scale was validated without any changes to the original scale form. The Turkish adaptation of E-RAS is a valid and reliable instrument for measuring apathy in adult epilepsy patients. Its use in clinical practice is strongly recommended. The E-RAS scale can be used to assess apathy in adults with epilepsy. The was determined that the adapted Turkish form had a similar structure to the original scale. It was determined that the E-RAS scale is valid and reliable in Turkish culture. The fact that the Turkish adaptation of the scale is similar to the original structure and other adapted cultures is a factor that facilitates its use and acceptance in international comparisons. The scale can be used to assess apathy in adults with epilepsy.

This study aims to assess the linguistic and cultural validity of the translated Multidimensional Scale of Perceived Social Support (MSPSS) in Persian, ensuring that the nuances of social support are adequately captured and comprehended by Iranian cancer patients. In this cross-sectional study, 400 cancer patients from Iran were assessed using the MSPSS. By using exploratory factor analysis (with Maximum Likelihood factor analysis and Promax rotation) and confirmatory factor analysis, the construct validity of this scale was assessed. To check for internal consistency, the average inter-item correlation, Cronbach's alpha, and McDonald's omega coefficients were used. Most of the participants ranged in age from 49 to 59 years (n = 102, 34%). Two factors were extracted from EFA and the total cumulative variance explained by these factors was 61% of the total variance. Item factor loadings varied between 0.613 and 0.949. Internal consistency coefficients were considered acceptable (>0.7). The Farsi version of the MSPSS as a self-report measure showed acceptable reliability and validity. Consequently, the scale can be used by nurses to evaluate perceived social support among Farsi-speaking cancer patients that can help them to take necessary actions to decrease the level of concern in these patients.

Professional socialization is a critical process that influences hospital nurses' professional identity, competence, and ethical standards, ultimately impacting the quality of patient care. This study aimed to translate the Professional Socialization Scale (PSS) for Hospital Nurses into Persian and evaluate its psychometric properties among Iranian nurses. A cross-sectional methodological study was conducted in two phases: translation and psychometric evaluation. A stratified sample of 511 nurses from both public and private hospitals in Kermanshah City, Iran, participated in the study. The scale was translated into Persian using the Douglas and Craig model, and its content and face validity were assessed. Construct validity was evaluated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The internal consistency of the scale was assessed using Cronbach's alpha and McDonald's omega coefficients, while test-retest reliability was evaluated using the intraclass correlation coefficient (ICC). The PSS scale maintained the meaning of the original English version and was clear and understandable for hospital nurses. In qualitative face validity, one item changed slightly and all items were retained in the quantitative face validity assessment. Each item's content validity ratio ranges from 0.71 to 1, the Item content validity index ranges from 0.79 to 1, while the Scale-level Content Validity Index was 0.89. The EFA and CFA confirmed a four-factor structure of the Persian version of the scale, with 21 items explaining 67.72% of the total variance. The model fit indices indicated excellent model fit. The scale demonstrated acceptable internal consistency (Cronbach's alpha = 0.908, McDonald's omega = 0.904) and test-retest reliability (ICC = 0.908). The Persian version of the PSS for Hospital Nurses is a valid and reliable instrument. Nursing managers should facilitate the professional socialization process for nurses. This scale can be used to assess the socialization of nurses and guide their career development.

The aim is to reevaluate the measurement properties of the Portuguese version of the Work Ability Index (WAI). A cross-sectional study was conducted with 3,051 nurses in the state of São Paulo. Participants answered a questionnaire on individual characteristics, working conditions, and WAI. Validity was assessed through discriminative analysis of known groups and exploratory factor analysis (EFA) with parallel analysis (PA). Reliability was assessed using Cronbach's alpha and McDonald's omega coefficients. In the analysis of known groups, all investigated individual and work variables showed statistically significant associations with WAI (p < 0.005). EFA revealed a unidimensional structure, which was confirmed by PA. The model proved to be appropriate (root mean square error of approximation = 0.125; Tucker-Lewis Index = 0.900), although the Comparative Fit Index = 0.882 was slightly lower than expected. Reliability was satisfactory (Cronbach's alpha coefficient = 0.787 and McDonald's omega = 0.819). The WAI continues to be a valid and reliable measure to evaluate work ability in the current context of Brazilian work.

The purpose of this study was to identify and test the factor structure of the Agricultural Producer Barriers to Care Scale (APBCS), which assesses barriers to engaging with health care in rural US farmers. Respondents (n = 1045) completed an online survey that was distributed digitally and in-person by researchers and community partners at farming events and via farm-related social media. Exploratory and Confirmatory Factor Analysis were used to assess the underlying factor structure of the APBCS, and McDonald's omega coefficients were calculated to test the reliability of each factor and the instrument as a whole. Data analysis was conducted in SPSS 28.0 and MPlus Version 7.4. The exploratory factor analysis (n = 689) indicated a four-factor structure for the APBCS with domains of (i) formal health care challenges, (ii) cultural barriers to help-seeking, (iii) stigma, and (iv) resilience, which explained 38.408% of the overall variance. The confirmatory factor analysis (n = 231) found that a three-factor structure, where questions from "cultural barriers to help seeking" were applied to factors for stigma and resilience, was a better fit for the model than the four-factor model hypothesized by the EFA. The final APBCS showed reliability within each domain, and across the full three-factor scale. The APBCS is a promising tool that shows high internal consistency and could inform researchers and practitioners about the structural and cultural barriers to engaging with health care in agricultural producers living in the United States.

Phubbing-the act of snubbing someone by concentrating on a smartphone-is claimed to be an increasing, even normative, behavior receiving more research attention. However, evidence about the adequacy of instruments that allow screening for phubbing is limited. Thus, the main purpose of the present study was to analyze the psychometric properties of the Phubbing scale in a sample of adolescents and young adults and present a reliable and valid short form. The final sample included a total of 1351 adolescent students (54.25% males), aged between 12 and 21. The study used a self-administered questionnaire with different scales for collecting data. A two-dimensional model of a short version of the PS with 6 items (PS-6) displayed appropriate goodness-of-fit indices. Strong measurement invariance for the two-dimensional model across gender and educational levels was confirmed. McDonald's Omega coefficients for the Communication, the Obsession, and the Total score of the PS-6 were 0.617, 0.669, and 0.701, respectively. The PS-6 was positively associated with several indicators of psychological difficulties and negatively associated with psychological well-being and self-esteem. The present study contributes valuable information about the psychometric adequacy of the PS-6, a short instrument that allows screening for Phubbing in adolescents and young adults.

A new version of the Sleep Hygiene Index (SHI-10) has recently been introduced, and the psychometric performance in other populations is unknown. This study aimed to determine the dimensionality, internal consistency, and nomological validity of the SHI-10 among medical students in Santa Marta, Colombia. A psychometric study was designed to determine indicators of validity (construct and nomological) and reliability (internal consistency) in which 309 medical students between 18 and 39 years (20.83±2.68) and 54.69% were female. Construct validity (dimensionality) was tested through confirmatory factor analysis, internal consistency with Cronbach's alpha and McDonald's omega coefficients, and nomological validity through correlations with the Athens Insomnia Scale, Epworth Somnolence Scale, Generalized Anxiety Disorder (GAD)-7) and Patient Health Questionnaire (PHQ-9). The four-dimensional structure of the SHI-10 showed adequate indicators of goodness of fit (Satorra-Bentler’s chi-square of 43.30 [df of 29, p=.04], chi-square/df of 1.49, RMSEA of .04 [90%CI .01-.06], CFI of .97, TLI of .96 and SRMR .04). The four dimensions of the SHI-10 showed values less than .70 and limited nomological validity (most Pearson correlations were less than .30). In conclusion, the SHI-10 shows a four-dimensional structure of SHI-10; however, the four dimensions of the SHI-10 present low internal consistency and limited nomological validity. More studies are needed to show the psychometric performance of the SHI-10.

Lesbian, gay, bisexual, and transgender (LGBT) individuals often face discrimination in healthcare settings, resulting in health disparities. Evaluating healthcare professionals' affirmative practices is essential for promoting inclusive care and addressing these disparities. The aim of this study was to assess the psychometric properties of the Spanish version of the Gay Affirmative Practice Scale (GAP-ES), which measures healthcare professionals' affirmative practices towards gay individuals. Before assessing its psychometric properties, the original Gay Affirmative Practice Scale (GAP) was translated and culturally adapted from English to Spanish. Following the translation, the psychometric properties were tested on a sample of 236 healthcare professionals. The internal consistency of the questionnaire was measured using Cronbach's alpha and the discriminatory power index. Factor structure was evaluated with Confirmatory Factor Analysis (CFA) using the Diagonally Weighted Least Squares method. The sample consisted of 152 female (64.41%) and 84 male (35.59%) participants, with 58.05% identifying as heterosexual, 28.81% as homosexual, and 13.14% as bisexual. The internal consistency of the GAP-ES was strong, with Cronbach's alpha values of 0.915 for the Beliefs subscale and 0.902 for the Behaviors subscale. The McDonald's Omega coefficient was 0.942, indicating high reliability. CFA confirmed a two-factor structure with satisfactory fit indices (CFI = 0.999, RMSEA = 0.071). The GAP-ES demonstrates strong internal consistency and a stable factor structure. It is a reliable tool for evaluating affirmative practices toward LGBT patients in Spanish-speaking healthcare contexts, supporting improved care for this population. The integration of the GAP-ES into clinical practice and training programs may support the enhancement of cultural competence among healthcare professionals, contributing to the reduction of health disparities for LGBT patients in Spanish-speaking settings.
