Cronbach alpha and Cohen kappa were compared and found to differ along two major facets. A fourfold classification system based on these facets clarifies the double contrast and produces a common metric allowing direct comparability. A new estimator, coefficient beta, is introduced in the process and is presented as a complement to coefficient alpha in estimating the psychometric properties of test scores and ratings.

Object This study was undertaken to assess the reliability of observations of postoperative photographs in assigning House-Brackmann scores as outcome measures for patients following resection of vestibular schwannomas. Methods Forty pictures of differing facial expressions typically elicited from patients for assigning House-Brackmann scores were individually evaluated by neurosurgery residents and faculty members at the University of Alabama at Birmingham; a score was assigned to each picture by the individual raters. The interrater reliability was measured using the Spearman correlation coefficient, Kendall coefficient of concordance, and kappa statistic; internal consistency was calculated using the Cronbach alpha reliability estimate. Results The Spearman correlation coefficients showed strong positive association among raters, with a range of values of 0.66 to 0.90. Internal consistency measured by the Cronbach alpha coefficient was excellent (α = 0.97). The Kendall coefficient of concordance for the ordinal grades suggested a substantial degree of agreement among the raters (w = 0.76, p < 0.001). Conclusions Static postoperative photographs are a reliable outcome measure for determining facial nerve function after vestibular schwannoma resection and may serve as a surrogate for the dynamic patient interview.

Zimet's knowledge of AIDS scale was completed anonymously by 2,209 university students to assess whether a split-half approach in which items in each half were matched for content would provide better estimates of reliability than other methods. Analysis indicated that the odd-even Spearman-Brown split-half reliability coefficient was lower than both the alpha coefficient and the content-based split-half coefficient. The Cronbach alpha was similar to the content-based Spearman-Brown reliability coefficient.

Objective: Internal consistency of scales is crucial for the quality of clinical practices, and scales that measure various aspects of clinical disorders must possess acceptable internal consistency. In the assessment of the internal consistency of the scales, the present study considered the Cronbachs alphas coefficient. This study aims (1) to provide a practical sample size guide based on Cronbachs alpha for medical researchers; (2) to investigate the factors related to the determination of the sample size needed for a correct estimation of Cronbachs alpha. Method: The calculation steps of the two sample size approaches (desired precision and desired power) proposed by Bonett are detailed and the sample size tables of these approaches are tabulated. Results: Findings indicate that as the number of items in the scale increases, the sample size decreases to a certain level but reaches a plateau when the number of items is about 30. Furthermore, it is claimed that the sample size should be at least 45 (and more) in order to calculate a meaningful internal consistency coefficient. Conclusions: In the present study, we extracted detailed information about the key components of sample size calculation for Cronbachs alpha and provided an easy and practical tables, which will enable clinicians to determine the appropriate sample size for their internal consistency studies.

This study aimed to develop a scale to determine the democratic behavior levels of children in early childhood. The study group included a total of 486 children attending kindergartens and primary school nursery classes in Melikgazi, Kayseri. Scale reliability was tested by using intra-group correlation values, item analysis coefficients, Cronbach’s Alpha reliability coefficient (0,98), and the Hotelling T2 test result [ 830,12 and (p<0.001)]. For validity testing purposes, the Cronbach Alpha coefficient, KMO test result (0,97), the Bartlett test and item analysis (p<0.001) were calculated. It was consequently decided that the scale was suitable for factoring, and AFA was used in principal component analyses. Following this, the structural equation model of DFA was performed, which confirmed that the model suited the data and that the 3-factor structure of the scale was valid. Confirmed as valid and reliable, the scale consisted of a total of 38 items in the sub-dimensions of "Knowing Your Rights", "Autonomous Behaviors" and "Democratic Behaviors". The highest score possible from the scale is 190, while the lowest possible score is 38.

The estimation of reliability in any research is a very important thing. For us to achieve the goal of the research, we are usually faced with the issue of when the measurements are repeated, are we sure we will get the same result? Reliability is the extent to which an experiment, test, or any measuring procedure yields the same result on repeated trials. If a measure is perfectly reliable, there is no error in measurement, that is, everything we observe is true score. However, it is the amount/degree of error that indicates how reliable a measurement is. The issue of sample size determination has been a major problem for researchers and psychometricians in reliability study. Existing approaches to determining sample size for psychometric studies have been varied and are not straightforward. This has made the psychometric literature to contains a wide range of articles that propose a variety of sample sizes. This paper investigated sample sizes in test-retest and Cronbach alpha reliability estimates. The study was specifically concerned with identifying and analyzing differences in test retest and Cronbach alpha reliability estimate of an instrument using various sample sizes of 20,30,40,50,100,150,200,300, and 400. Four hundred and eight (408) senior secondary school students from thirty-eight (38) public senior secondary schools in Benin metropolis part took in the study. The Open Hemisphere Brain Dominance Scale, by Eric Jorgenson was used for data collection. Data were analyzed using Pearson Product Moment Correlation Coefficient (r) and Cronbach alpha. The findings revealed that the sample sizes of 20 and 30 were not reliable, but the reliability of the instrument became stronger when the sample size was at least 100. The interval estimate (Fishers confidence interval) gave a better reliability estimate than the point estimate for all samples. Based on the findings, it was therefore recommended that for a high reliability estimate, at least one hundred (100) subjects should be used. Observed or field tested values should always be used in the estimation of the reliability of any measuring instrument, and reliability should not be reported as point estimate, but as interval.

Background/Aims This study aimed to translate the perceived insufficient milk questionnaire into the Chinese language, Mandarin, perform cultural adaptation, and evaluate its validity and reliability. Methods The perceived insufficient milk questionnaire was translated using a forward-backward process. An expert panel evaluated content validity with both item and scale content validity indices. Construct validity was assessed by exploratory and confirmatory factor analysis. Internal consistency reliability was evaluated by the Cronbach alpha coefficient. With a 1-week interval, the test-retest reliability was assessed by intraclass correlation coefficient. Results A total of 328 participants were recruited. The item-level content validity index was as high (0.83–1.0), and the scale-level content validity index was 0.92, indicating excellent validity. A single-factor model was verified as acceptable with good fit indices. The internal consistency (Cronbach alpha coefficient=0.943) and test-retest reliability (intraclass correlation coefficient range: 0.870–0.974) were good. Conclusions The Chinese version of the perceived insufficient milk questionnaire had acceptable validity and reliability. It is helpful for healthcare providers to evaluate mother's beliefs about breastmilk quantity and nutritional quality, preventing early cessation of breastfeeding through timely interventions.

The purpose of this study was to investigate both the internal consistency and temporal reliability of the Measure of Self-actualization of Potential. Results from the initial pilot study ( n = 414) used to develop the inventory are compared with those of a new sample ( n = 156) designed to evaluate its stability. Responses from the new sample support our initial findings of moderate to relatively high alpha coefficients for the two main scales and five subscales. Test-retest reliability for the new set of responses indicates high stability, with intraclass correlation coefficients ranging from .74 to .88. For the over-all scale, Cronbach alpha reaches .90 and the intraclass coefficient .87. In addition to better psychometric properties, the new inventory has two other advantages over the Personal Orientation Inventory, fewer items and a self-report format.

Full textAbstract:
Mindfulness-based approaches, which have been used in many fields in recent years, have been widely accepted especially in practices in psychology and psychiatry, and have been integrated into traditional treatment methods. In parallel with the positive effects of the concept of mindfulness on mental, spiritual and physical well-being, researches have also steadily increased and various scales have been developed to measure mindfulness which can be summarized as the mindful awareness of the moment by accepting one’s experience without judgment.Some of these scales were adapted to Turkish in the last decade. Considering the extensive usage of the concept of mindfulness in health-related fields, this study aimed to introduce the State Mindfulness Scale into Turkish, as one of the important scales to be evaluated on a more solid theoretical and methodological basis. Accordingly, the source scale was translated into Turkish through the steps suggested by WHO. Confirmatory factor analysis (CFA) was performed for the validity of the scale. Cronbach alpha reliability coefficient, Item Total Score Analysis, Guttman reliability coefficients, Spearman-Brown confidence coefficients were evaluated and the findings regarding the internal consistency of the scale were used in terms of the reliability analysis of the scale. For CFA and other analyses, 345 students at Akdeniz University were included in the study. As a result of CFA, it was found that the 21 item 2-factor structure in the source scale was compatible with the target culture (X2/Sd: 3,41; RMSEA: 0,088: CFI: 0,95). The correlation reliability coefficients of the scale ranged from 0.484 to 0.743. The Cronbach alpha value of the first factor of the scale was 0.899, the Cronbach alpha value of the second factor was 0.728, and the Cronbach alpha value for the total score was 0.921. The findings show that the validity and reliability of the State Mindfulness Scale has been ensured and the scale has been successfully adapted to Turkish.

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.

This study aims to examine the relationship between leisure time satisfaction and life satisfaction of university students receiving Reformer Pilates training. For this purpose, 234 people from Afyonkarahisar province, reached by purposeful sampling method, constituted the research participants. Leisure Satisfaction Scale developed by Beard and Raghep (1980) and The Satisfaction with Life Scale developed by Ed Diener et al. (1985) was used as a data collection tool. The Cronbach Alpha reliability coefficient of the Leisure Satisfaction Scale was 0.76, and the Cronbach Alpha reliability coefficient of the life satisfaction scale was 0.70. For the sub-dimensions of the leisure satisfaction scale, the internal consistency coefficients ranged from 0.70 to 0.89. Validity and reliability analysis (EFA) of the obtained data was performed, then confirmatory factor analysis (CFA) and structural equation modeling (SEM) were applied. As a result of the established model (RMSEA = .07, CFI = .96), a highly significant relationship was found between leisure time satisfaction and life satisfaction (p0.05). It was found that the leisure time satisfaction levels of female students who took the reformer pilates training had a high effect on life satisfaction. The findings suggest that reformer pilates training plays an important role in increasing life satisfaction in young women as a leisure time evaluation tool.

ABSTRACTCaregivers of demented patients are under significant stress along with physical, psychological or social problems. Standardized and validated instruments are required for measuring consequences of caregiving or efficacy of support interventions. Reliability of French translation of these instruments has to be verified in order to confirm their psychometric properties. The goal of the present study is to assess reliability of the French translation of three instruments designed for evaluation of caregivers of demented patients. The Zarit's Burden Interview (BI) is a 22-items scale measuring the subjective burden of the caregiver. The Revised Memory and Behavior Problems Checklist (RMBPC), a 53 item scale, measures frequency of memory and behaviour problems of demented patients and the caregiver's reaction to these problems, which is another mean of burden assessment. The Alzheimer's Disease Knowledge Test (ADKT) assesses knowledge of caregivers about demented diseases and resources available using 20 multiple choice questions. A reliability study was conducted on a sample of 40 caregivers. The caregivers were questioned twice, the second time after one (N = 26) or eight (N = 14) weeks. The BI internal consistency (Cronbach alpha) yielded a coefficient of 0.85 and test-retest reliability (intra-class correlation coefficient) was 0.89. The RMBPC's Cronbach Alpha was 0.93 for frequency and 0.94 for reaction. Intra-class correlation coefficients were 0.77 (frequency) and 0.90 (reaction) for RMBPC and 0.71 for ADKT.

Full textAbstract:
Background Work addiction is a significant public health problem with a growing prevalence. The Work Addiction Risk Test (WART) is the gold standard questionnaire to detect workaholism. Objective The main objective of this study was to validate the French version of the WART. Methods Questionnaires were proposed to voluntary French workers using the WittyFit software. There were no exclusion criteria. The questionnaire was administered anonymously for initial validity testing and readministered one week later for test-retest reliability. We also assessed the workers’ sociodemographic characteristics, as well as other measurements for external validity, such as stress, well-being, and coaddictions to tobacco, alcohol, and cannabis. Several psychometric properties of the French-WART were explored: acceptability, reliability (internal consistency [Cronbach alpha coefficient] and reproducibility [Lin concordance coefficient]), construct validity (correlation coefficients and principal component analysis), and external validity (correlation coefficients). Results Among the 1580 workers using WittyFit, 187 (11.83%) agreed to complete the WART questionnaire. Of those, 128 completed the test-retest survey (68.4%). Acceptability found that all respondents had fully completed the questionnaire, with few floor or ceiling effects. Reliability was very good with a Cronbach alpha coefficient at .90 (internal consistency) and Lin concordance coefficient at .90 (95% CI .87-.94] with a difference on the retest of .04 (SD 4.9) (95% CI −9.6 to 9.7) (reproducibility). We identified three main dimensions (construct validity). Relationships between WART and stress and well-being confirmed its external validity. Conclusions The French version of the WART is a valid and reliable instrument to assess work addiction with satisfactory psychometric properties. Used in occupational medicine, this tool would allow the diagnosis of work addiction and can be easily implemented in current practice.

Introduction. Health-related quality of life (HRQL) of chronic patients has been researched as the ultimate goal of modern treatment of chronic diseases to improve patients? quality of life. Objective. The objective was to assess the reliability of the Serbian version of the Sickness Impact Profile (SIP) questionnaire on the sample of patients with chronic viral hepatitis. Methods. The research covered 102 patients with chronic hepatitis (47 type B and 55 type C). The assessment of the reliability of the SIP questionnaire was performed by testing the internal consistency of the questions by calculating the Cronbach?s alpha coefficient. The factor analysis was used to assess whether the grouping of the questions within dimensions matches the distribution of the questions in the original English version of the questionnaire administered to U.S. patient population. Results. The Cronbach?s alpha coefficient for the entire questionnaire is 0.925, 0.869 for the physical dimension, and 0.857 for the psychosocial dimension. After running a factor analysis of the psychosocial dimension, ?emotional instability? was extracted as the key factor, confirming the results of previous research. Compared with the English version of the questionnaire, the Cronbach?s alpha coefficient of the Serbian version does not diverge significantly, whereas the factor analysis confirms the classification of the questionnaire into two dimensions. Conclusion. Our study has shown that the Serbian version of the SIP questionnaire is a reliable tool for assessing the HRQL of patients with chronic hepatitis B and C before starting treatment.

The field research design applied the quantitative approach. The research population, 5.915 respondents, came from elements of the academic community at the Vocational Education Program, Brawijaya University, Malang, and the Vocational Faculty, Airlangga University, Surabaya. Then, the sampling technique determined 98 samples based on the Stratified Random Sampling approach. Data collection techniques were supported by questionnaires, documentation, and interviews. In order to facilitate the analysis, we used parametric inference statistical analysis techniques to test the validity and reliability. The results of the validity test through correlation (Pearson Correlation Coefficient) and the reliability test with the Cronbach Alpha method (Cronbach's Alpha) showed that all question items had been proven to be valid based on the sig value 0.05. From 18 items, the Cronbach alpha value was 0.785. As it was more than 0.6, the questionnaire was valid. Also, the reliability test of 16 items obtained from Cronbach's alpha value was 0.838. It was more than 0.6, meaning that the questionnaire was valid. The correlation value between items 1-18 had a fairly high correlation, and the view of the question value sig. 2 tailed overall was 0.05, meaning that each question item was valid. The findings from this study indicated that the existence of learning policies has a significant influence on the vocational learning process during the Covid-19 pandemic. This study recommends that in the post-Covid-19 pandemic, educational policies in higher education units of vocational type are more adaptive to digital-based learning by strengthening health principles and protocols.

Introduction: Long head of biceps (LHB) pathologies are an important cause of pain and dysfunction. As LHB pathologies have specific components from other underlying or related pathologies, the LHB score is designed for an accurate assessment. The aim of this study was to adapt the LHB score into Turkish and to assess its validity and reliability. Materials and Methods: LHB score was translated and culturally adapted from English to Turkish, and then it was applied to 62 patients with biceps long head pathology. The reliability of the scale was checked through internal consistency and test–retest methods. Internal consistency was computed with Cronbach alpha value. Test–retest reliability was assessed using an intraclass correlation coefficient. American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form and modified Constant–Murley score were used to analyze concurrent validity. Results: The Cronbach alpha value of the scale was found as .640. When the subsections of LHB score were computed separately, Cronbach alpha levels of pain/cramps and cosmesis sections were found as .753 and .774, respectively. The intraclass correlation coefficient value of the scale was found to be excellent (.940; P < .001). The total LHB score was determined to have a good positive correlation with the American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form (.527) and Constant–Murley score (.516). But an excellent correlation was revealed between the pain/cramps section of LHB score and other pain sections in American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form (.811) and Constant–Murley score (.816) (P < .001). There was an excellent correlation (.916) between cosmesis section and Popeye sign (P < .001). There was a moderate correlation (.469) between elbow-flexion strength section of LHB score and the digital handheld dynamometer outcomes (P < .001). Conclusion: The Turkish version of the LHB is a valid and reliable tool, especially for biceps pathologies.

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.

Full textAbstract:
BACKGROUND The Naranjo criteria are frequently used for determination of causality for suspected adverse drug reactions (ADRs); however, the psychometric properties have not been studied in the critically ill. OBJECTIVE To evaluate the reliability and validity of the Naranjo criteria for ADR determination in the intensive care unit (ICU). METHODS All patients admitted to a surgical ICU during a 3-month period were enrolled. Four raters independently reviewed 142 suspected ADRs using the Naranjo criteria (review 1). Raters evaluated the 142 suspected ADRs 3–4 weeks later, again using the Naranjo criteria (review 2). Inter-rater reliability was tested using the kappa statistic. The weighted kappa statistic was calculated between reviews 1 and 2 for the intra-rater reliability of each rater. Cronbach alpha was computed to assess the inter-item consistency correlation. The Naranjo criteria were compared with expert opinion for criterion validity for each rater and reported as a Spearman rank (rs) coefficient. RESULTS The kappa statistic ranged from 0.14 to 0.33, reflecting poor inter-rater agreement. The weighted kappa within raters was 0.5402–0.9371. The Cronbach alpha ranged from 0.443 to 0.660, which is considered moderate to good. The rs coefficient range was 0.385–0.545; all rs coefficients were statistically significant (p < 0.05). CONCLUSIONS Inter-rater reliability is marginal; however, within-rater evaluation appears to be consistent. The inter-item correlation is expected to be higher since all questions pertain to ADRs. Overall, the Naranjo criteria need modification for use in the ICU to improve reliability, validity, and clinical usefulness.

OBJECTIVE: To evaluate internal consistency and temporal stability trough test re-test reliability of the Portuguese version of the Social Phobia and Anxiety Inventory (SPAI) in a heterogeneous Brazilian sample. METHODS: After informed consent, the translated and adapted version of the SPAI Portuguese was tested and re-tested at a 14-day interval in a sample of 225 university students, both genders, from 4 different undergraduate courses. After double data entry, statistical analysis included Cronbach's alphas, Pearson and intra-class correlation coefficients. RESULTS: The studied sample consisted of 213 students from 4 sub-samples: 95 law students, 31 social communication students, 54 civil engineering students and 33 dental medicine students. The mean age was 23 (±6) years and 110 (51.6%) were female. The Cronbach' alpha was 0.96, no difference for both genders. The differential (total) score of the SPAI Portuguese showed Pearson coefficient 0.83 (95% CI 0.78-0.87) and Intra-class coefficient 0.83 (95% CI 0.78-0.86). There was no statistical difference in Pearson coefficients between genders (p = 0.121) and the 4 sub-samples (p = 0.258). CONCLUSION: The results do not ensure validity, however, the SPAI Portuguese version presented a good content homogeneity with satisfactory level of internal consistency. The temporal stability evaluated was substantial. The results showed that the Portuguese SPAI presents perfectly acceptable reliability for both genders and suggest that it can be used in Brazilian populations

Background Nomophobia or phobia of no mobile phone is the fear of being without a mobile phone or being unable to contact others via a mobile phone. It is a newly emerging psychiatric disorder among mobile phone users. Objective There are no psychometric scales available in China for examining nomophobia, although China has become the largest mobile phone handset consumer market in the world. Therefore, this study aimed to translate the original English version of a psychometric scale into Chinese and further examine its reliability and validity among Chinese college students. Methods The original version of the Nomophobia Questionnaire (NMP-Q) was first translated into Chinese using the backward and forward translation procedure. An exploratory factor analysis (a principal component analysis plus varimax rotation) and a confirmatory factor analysis (CFA) were performed to examine the underlying factor structure of the translated questionnaire. The internal consistency reliability of the scale was determined by computing the Cronbach alpha coefficient, the test-retest reliability, and the corrected item-total correlation. A multivariate regression analysis was used for examining associations between nomophobia and independent variables among the college students. Results A total of 2000 participants were included in the study. Their ages ranged from 16 to 25 years, with 51.95% (1039/2000) being male participants. The Chinese version of NMP-Q retained 18 items. The eigenvalues, total variance explained, and scree plot jointly support a 4-factor structure of the translated questionnaire. The CFA reached the adaptive standard, and the discriminant validity of the scale was good. The Cronbach alpha coefficient of this scale was .925, and the Cronbach alpha coefficients of the subscales were .882, .843, .895, and .818. The test-retest reliability was 0.947. Corrected item-total correlation ranged from 0.539 to 0.663. The significant predictors for each of the dimensions of nomophobia and total score of the questionnaire were the average number of hours spent on a mobile phone daily and gender. Conclusions The Chinese version of the NMP-Q exhibited satisfactory psychometric properties.

This study aimed to evaluate the validity and reliability of the Turkish version of the Schizophrenia Hope Scale (SHS). This methodological study was carried out with 214 participants diagnosed with schizophrenia who were followed up in the psychiatry outpatient clinics of a university hospital between August 2021 and August 2022. Data were collected using an Information Form and the Schizophrenia Hope Scale (SHS). Language and content validity, exploratory and confirmatory factor analyses, item-total correlation, Cronbach alpha coefficient, and test-retest reliability methods were used in the validity and reliability analysis of the scale. As a result of the exploratory factor analysis, no item was excluded from the scale and it was determined that the scale has nine items and a single-factor structure. The single-factor structure of the scale was confirmed with the confirmatory factor analysis. The Cronbach Alpha coefficient of the scale was 0.901 and the factor loads ranged between 0.70 and 1.0. The test-retest correlation coefficient was r=0.959. The Turkish version of the scale was found to be valid and reliable. SCH is important since it represents the subjective meaning of hope from schizophrenic patients’ perspective and allows an easier measurement of the level of hope in this population. Mental health professionals can use SHS to determine or increase the level of hope of schizophrenia patients in their studies.

Methods: 14 volunteer violinists aged 18.6 (SD 2.1) with a body mass index 20.05 (SD 2.3) were recruited. The violinists performed a legato bowing task. The DAid smart shirt worked as the assessment tool: a compression garment with textile strain sensors sewn onto it. Cronbach alpha coefficient, Interclass Correlation Coefficient were calculated to assess the within-session test-retest reliability. Results: An excellent and good result test-retest reliability was assessed in 57% of the violinists, for other 43%, the ICC and Cronbach alpha coefficient was less than 0.59. Conclusion: the DAid Smart shirt is reliable for shoulder girdle motion assessment during high string performance. The smart textile garment should be customized and suitable for the body in order to assess shoulder girdle motion during high level or advanced activities such as high string performance.

Full textAbstract:
Coefficient alpha is the most commonly used internal consistency reliability coefficient. Alpha is the mean of all possible k-split alphas if the items are divided into k parts of equal size. This result gives proper interpretations of alpha: interpretations that also hold if (some of) its assumptions are not valid. Here we consider the cases where the items cannot be split into parts of equal size. It is shown that if a k-split is made such that the items are divided as evenly as possible, the difference between alpha and the mean of all possible k-split alphas can be made arbitrarily small by increasing the number of items.

Objective: The aim of this study is to make the Turkish validity and reliability of the vaccine hesitation scale to be used in combating experienced or possible pandemics in the future. Methods: It is a methodological study in which the Turkish validity and reliability of the "Vaccine Hesitancy Scale" developed by Larson et al. (2015) was modified for pandemics. Explanatory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were conducted with the data collected from 617 volunteers for construct validity. Cronbach's Alpha Coefficient and language and construct validity were performed for reliability and validity. Results: As a result of EFA and CFA, the 10-item "Vaccine Hesitancy Scale in Pandemics" showed a two-factor structure. The two-factor structure explains 68.53% of the total variance. Factor loadings related to the items of the scale vary between 0.638 and 0.887. Confirmation of EFA results with CFA results was found to provide construct validity. It was observed that the reliability criterion was met by determining the Cronbach Alpha Coefficient as 0.901. Conclusion: It is thought that the "Vaccine Hesitancy Scale in Pandemics", which has been conducted with the data obtained from people with different socio-demographic characteristics of the Turkish people, can be a reference that can be used by researchers as a valid and reliable measurement tool.

Introduction and aim: This study investigates the validity and reliability of the Subjective Perception of Post-Operative Functional Impairment of the Arm (SPOFIA) scale in patients with postoperative breast cancer. Materials and methods: Research was designed as a methodological type. Required permissions were taken from the ethics committee, relevant institutions, and researchers who developed the SPOFIA scale. Data were collected as a research in Kocaeli University hospital, between November 2017 and October 2018. For the Turkish SPOFIA scale’s validity, data were collected from 142 patients. In the study, Patient Information Form, SPOFIA, and 36-item Short-Form Health Survey (SF-36) Quality-of-Life Questionnaire were used. In the analysis of data, descriptive statistical methods were used, and in the analysis of the validity of the scale, test-retest and Cronbach alpha reliability coefficient was used. Results: As a result of the analysis, we obtained Kendall W = 0.107, P > 0.05; correlation with SF-36 was P < .05, reliability studies test-retest analysis was P > .05, and Cronbach alpha reliability coefficient was 0.739. It was determined that the SPOFIA scale was valid and reliable for Turkish patients and that the subjective findings of the patients could be used as individual follow-up in longitudinal monitoring. Conclusions: As a result, it was determined that the SPOFIA scale was reliable in the patient follow-up of breast cancer women.

Responses of 228 subjects were factor analyzed. The analyses identified three independent factors. Analyses of variance, Cronbach alpha coefficient, and K-R-20 formula for estimation of reliability show the scale to be reliable and homogeneous. Domain sampling method for the estimation of reliability is very low for the full scale and moderate for the three independent scales. Item analyses and criteria validity are also reported. Taking gain in income as a criterion of success, the criterion validity of the scale is zero.
