Abstract:
A permutation procedure to compute a resampling probability value and empirical quantile limits is provided for Cronbach's alpha measure of internal reliability. The underlying assumptions for the conventional use of alpha are discussed. The use of a permutation test for Cronbach's alpha is highlighted as a valuable tool when sample sizes are small and necessary assumptions cannot be met.

Abstract:
Cronbach alpha coefficient is still commonly used in research dedicated to the development of psychologicaltests. However, there is a certain lack of understanding of the significance of real and, especially, has its limits.The article presents the fundamental postulates of classical test theory and analyzes, in this context, the mainissues affecting the calculation and interpretation of Cronbach alpha coefficient: unidimensionality, internal consistency,item number, characteristics of the data, the sampling error. Finally, are summarized recommendationsof good practices on the use and reporting Cronbach's alpha.

A translation of the Rathus Assertiveness Schedule (Rathus, 1973) was tested for psychometric properties on two Swedish samples of college students. Scores from the first sample ( n = 144) indicated high reliability for the original scale (Cronbach's alpha = .82) and an item analysis showed that the scale if shortened by six items had improved reliability (Cronbach's alpha = .84). This new scale, tested for validity on another sample ( n = 28), showed acceptable discriminative validity. The shortened version is recommended for use in different kinds of settings.

Abstract:
RESUMENLa introducción del enfoque de aprendizaje por competencias, consecuencia del proceso de convergencia europea, ha supuesto para el titulado en Pedagogía una mayor profesionalización de su formación. No obstante, dicho planteamiento requiere de procesos de revisión y evaluación que garanticen un vínculo efectivo entre la oferta educativa y el mundo laboral. En este contexto, el objetivo del presente trabajo es abordar el diseño y validación de la Escala de Competencias Específicas para Graduados en Pedagogía (ECEG-P). En el estudio participaron 275 egresados del Título de Grado en Pedagogía de la Universidade de Santiago de Compostela. Se analizaron las propiedades psicométricas de la ECEG-P por medio de análisis factoriales, análisis de correlaciones, y fiabilidad a través del alfa de Cronbach. Los resultados obtenidos informan de una estructura compuesta por dos factores, con un valor de alfa de Cronbach superior a .96 en ambos casos. Las correlaciones entre las competencias específicas y el nivel de ajuste de la formación a las necesidades del mercado laboral son significativas, apoyando la validez de constructo de la escala. Se obtuvieron valores alfa de Cronbach de .98, evidenciando la consistencia interna del instrumento. En conclusión, los resultados aconsejan la utilización de la ECEG-P en el estudio de las competencias específicas del graduado en Pedagogía. ABSTRACT The introduction of the competency-based learning approach as a consequence of the European convergence process, has meant for the graduate in Pedagogy a greater professionalization of their training. However, this approach requires processes of review and assessment that guarantee an effective link between the educational provision and the world of work. In this context, the aim of this paper is to design and validate the Specific Competences for Graduates in Pedagogy Scale (ECEG-P). The study involved 275 graduates in Pedagogy from the University of Santiago de Compostela. The psychometric properties of the ECEG-P were examined through factor analysis, correlation analysis, and reliability (Cronbach's alpha). The results report a two-factor structure, with a value of Cronbach’s Alpha above .96 in both cases. The correlations between the specific competences and the level of adjustment of the training to employment are significant, supporting construct validity of the scale. Cronbach's alpha values of .98 were obtained, highlighting the internal consistency of the instrument. In conclusion, the results suggest the use of the ECEG-P in the study of the specific competences of the graduate in Pedagogy.

Objectives: To test the psychometric properties of the Suicidal Ideation Questionnaire (SIQ) among Chinese high school students. Methods: The reliability and validity of SIQ were analyzed with data of 505 high school students in Jinan, China. Results: The Cronbach's coefficient alpha of SIQ was above 0.95 and the Cronbach's coefficients alphas of SIQ when each item was deleted were relatively stable. The convergent validity analyses showed that there were statistically significant correlations between SIQ total scores and DSD total scores by gender. Exploratory factor analysis produced four factors of SIQ. Conclusion: The SIQ has a high level of reliability and validity and should be a reliable measure for suicide ideation in Chinese high school students.

Introduction: Women's screening beliefs play an important role in their performance. Since a short form questionnaire is necessary in the assessment of screening beliefs in Iranian society, this study was conducted with the aim of psychometric evaluation of the Breast Cancer Screening Beliefs Questionnaire (BCSBQ) among Iranian women. Methods: In this cross-sectional methodological study, 300 Iranian women who were aged 18 years or older, and who were attending healthcare centers of Shahid Beheshti University of Medical Sciences, were selected in 2017-18. After a backward-forward translation procedure of BCSBQ was carried out, the face, content and construct validity of breast cancer-screening beliefs questionnaire were evaluated. In addition, the reliability was measured using the Cronbach's alpha and intra class correlation coefficients. Results: The results of the exploratory and confirmatory factor analysis were used to extract three distinct factors, including: attitude, knowledge, and barriers to screening. The three-factor model fit was accepted for all factors based on standard indices (RMSEA = 0.12, χ2 = 2.832, GFI = 0.87, AGFI = 0.8, CFI = 0.94, NFI = 0.92). In addition, the instrument’s reliability was measured using the Cronbach's alpha coefficient. The instrument had an appropriate Cronbach alpha (0.78). The interclass correlation coefficient was obtained to be 0.93 within a range of 0.83-0.97. Conclusion: The three-factor structure of the BCSBQ-12 had appropriate validity and reliability among Iranian women. Considering its appropriate psychometric properties, this instrument can be employed in subsequent studies to measure women's breast cancer screening beliefs in Iran.

Abstract:
This study aimed to verify the association between self-care ability and sociodemographic factors of people with spinal cord injury (SCI). It was a cross-sectional study, conducted in 2012, in all 58 Basic Health Units of Natal/RN, Brazil. Seventy-three subjects completed a sociodemographic form andSelf-Care Agency Scale. Statistical analyses were performed using SPSS,including Cronbach’s Alpha, Chi-square, Fisher’s and contingency coefficient tests. The Cronbach's alpha was 0.788. The result verified that sex (p = 0.028), religion (p <0.001), education (p = 0.046), current age (p = 0.027), SCI time (p = 0.020) and the SCI type (p = 0.012) were variables associated with self-care ability of the subjects. It was concluded that sociodemographic factors may interfere with the self-care ability of persons with SCI, and nurses should consider this aspect during the execution of the nursing process.

Background. Over the last 15 year, DREEM was applied in various educational settings to appraise educational climate. So far, none of article reported its stability in Malaysian medical students.Objective. To determine stability of the DREEM to measure educational climate at different time and occasions using a sample of medical students.Methodology. A prospective cohort study was done on 196 first year medical students. It was administered to the medical students at four different intervals. The Cronbach's alpha and intraclass correlation analysis were applied to measure internal consistency and agreement level across the intervals. The analysis was done using SPSS 18.Result. A total of 186 (94.9%) medical students responded completely to the DREEM inventory. The overall Cronbach's alpha value of the DREEM at the four measurements ranged between 0.91 and 0.94. The average Cronbach's alpha values of the five subscales ranged between 0.45 and 0.83. The ICC coefficient values for the DREEM total score was 0.67 and its subscales ranged between 0.51 and 0.62.Conclusion. This study supported satisfactory levels of stability and internal consistency of the DREEM to measure educational climate over multiple observations in a sample of Malaysian medical students.

Abstract:
Background and Purpose: Patients who have coexisting medical conditions tend to be more depressed. The purpose of this study was to examine the reliability, validity, and dimensionality of the Patient Health Questionnaire-9 (PHQ-9) in patients with heart failure and gastrointestinal (GI) symptoms. Methods: The cross-sectional data for this secondary analysis were collected in four studies. Cronbach's alpha was used to examine reliability. Concurrent validity with the Beck Depression Inventory-II (BDI-II) was examined. Results: Cronbach's alpha for the PHQ-9 was .87. Concurrent validity with BDI-II was excellent (r = .78, p < .01). Conclusions: The evidence from this study supports the reliability and validity of the PHQ-9 as a measure of depression in patients with heart failure and GI symptoms.

Abstract:
Background and Purpose: Patients with heart failure (HF) often have increased hostility. The Brief Symptom Inventory (BSI) Hostility subscale has not been evaluated in this population. The purpose of this study was to explore dimensionality, internal consistency, and construct validity of BSI Hostility subscale in HF. Method: Measures examined were BSI Hostility, Depression, and Anxiety subscales; Patient Health Questionnaire-9 (PHQ-9); and Multidimensional Scale of Perceived Social Support (MSPSS). Cronbach's alpha, exploratory factor analysis, and correlational analysis were used. Results: Cronbach's alpha for the BSI Hostility subscale was .77. Hostility was positively associated with the PHQ-9, BSI Depression, and Anxiety subscales and negatively related to the MSPSS. Discussion: The BSI Hostility subscale provides a reliable and valid measure of hostility in patients with HF.

Abstract:
Background and PurposeInstruments to measure pain must be cross-culturally adapted through rigorous processes, so they can provide equivalence of measure regardless of the context in which they are applied. The study aim was to perform a cross-cultural adaptation of Multidimensional Pain Evaluation Scale (MPES) for use in the United States.MethodsCross-cultural adaptation study entailed translation, back translation, and review by a committee, face and content validity and pilot testing with 90 participants with acute or chronic pain from United States. The Cronbach's alpha coefficient was calculated.ResultsSome items of MPES was changed to maintain the highest level of similarity between the original scales in Portuguese and adapted to English.ConclusionThe Cronbach's alpha was high showed this scale has internal consistency and reliability.

Abstract:
Background and PurposeNipple shield use is common among breastfeeding mothers, yet no instrument measures maternal satisfaction. The new Maternal Nipple Shield Satisfaction Scale (MNSSS) was evaluated for reliability and validity.MethodsThe MNSSS for was tested in two phases: women (N = 128) using nipple shields in the previous 6 months and the second, women, (N = 57) within the first 3 weeks postpartum.ResultsFrom the original 21-item scale, content validity analysis, Cronbach's alpha, item to total correlation testing, exploratory factor analysis resulted in a one factor scale consisting of nine items with a Cronbach's alpha of .90. Convergent validity testing resulted in a small, but significant negative correlation.ConclusionThe MNSSS may be a useful instrument for examining satisfaction of women using nipple shields for breastfeeding.

Abstract:
Climate change poses significant health risks. Nurses assess, treat, and educate patients about health risks. However, nurses' level of awareness, motivation, and behaviors related to climate change and health is not known. This study developed and tested a novel tool measuring these elements. Three hundred fifty-seven nurses responded to the overall survey. Exploratory factor analysis (EFA) assessed the factor structure of the 22-item CHANT survey and Cronbach's alpha estimated internal consistency. A five-factor model was retained through the EFA, demonstrating good model fit (comparative fit index [CFI] = .95, root mean square error of approximation [RMSEA] = .04, standardized root mean square residual [SRMR] = .09), and items were internally consistent (Cronbach's alpha for each subscale >.70). CHANT has been developed and psychometrically examined and is ready for further use and study.

Abstract:
Background and Purpose: The Caring Loneliness Scale (CARLOS) includes 5 categories derived from earlier qualitative research. This article assesses the reliability and construct validity of a scale designed to measure patient experiences of loneliness in a professional caring relationship. Methods: Statistical analysis with 4 different sample sizes included Cronbach's alpha and exploratory factor analysis with principal axis factoring extraction. Results: The sample size of 250 gave the most useful and comprehensible structure, but all 4 samples yielded underlying content of loneliness experiences. The initial 5 categories were reduced to 4 factors with 24 items and Cronbach's alpha ranging from .77 to .90. Conclusion: The findings support the reliability and validity of CARLOS for the assessment of Finnish breast cancer and heart surgery patients' experiences but as all instruments, further validation is needed.

Abstract:
Background and Purpose: The purpose of this study was to develop a reliable and valid measure of faculty response patterns to the needs of underrepresented minority (URM) nursing students. Methods: A mixed-method approach. Results: The 10-item scale was found to be valid (content validity index [CVI] = .81) and reliable (Cronbach's alpha = .81). Principle component factor analysis with varimax rotation yielded a 3-factor solution that explained 66% of the variance in faculty engagement with URM students. The Cronbach's alpha for the 3 factors ranged from .72 to .78. Higher scores were associated with older faculty who had been teaching longer and had more experience teaching URM students. Conclusion and Implications: The results of the study provide preliminary evidence for the internal consistency and content, criterion-related, and construct validity of the scale.

Abstract:
Background and PurposeCardiovascular disease (CVD) is a major cause of death in the United States. The military are viewed as fit, ready to fight and that jumping out of perfectly good airplane or going to war is a greater risk than CVD. The purpose of this study was to determine reliability and validity of the Cardiovascular Risk Perception Survey (CRPS).MethodsA cross-sectional descriptive design was performed, supported by the Health Belief Model. Internal consistency reliability (Cronbach's alpha) and validity (principal component analysis) were examined.ResultsFifty-five participants were included in this study. Construct validity of the CRPS was supported by principal component analysis; indicating one scale that measured cardiovascular risk perception. The Cronbach's alpha is reported .865.ConclusionInitial psychometric testing of the CRPS provides evidence for construct validity and internal consistency reliability.

Abstract:
Introduction. Most dietary questionnaires are not created for use in a clinical setting for an adult health exam. We created the Healthy Eating Vital Sign (HEVS) to assess eating behaviors associated with excess weight. This study investigated the validity and reliability of the HEVS. Methods. Using a cross-sectional study design, participants responded to the HEVS and the Block Food Frequency Questionnaire (BFFQ). We analyzed the data descriptively, and, with Pearson’s correlation and Cronbach coefficient alpha. Results. We found moderate correlation (rho>0.3) between multiple items of the HEVS and BFFQ. The Cronbach's alpha was 0.49. Conclusion. Our results support the criterion validity and internal reliability of the HEVS as compared to the BFFQ. The HEVS can help launch a dialogue between patients and providers to monitor and potentially manage dietary behaviors associated with many chronic health conditions, including obesity.
