Background: Guy’s Neurological Disability Scale (GNDS) is designed to assess disability (i.e. activity limitations) in patients with multiple sclerosis. It contains 12 functional domains, each indicating a level of disability. Four domain scores and a total score can be calculated. Objective: The aim of this study was to evaluate the structural validity of the GNDS in a Dutch population who were definitely diagnosed as having multiple sclerosis. Methods: Data of 974 patients were available. The structural validity of the GNDS was evaluated by confirmatory item factor analysis (CIFA). Two first-order models and two bifactor models were investigated. Results: The best fitted model was a bifactor model with a general factor underlying all items, and 10 items loading on 3 group factors. Cronbach’s alpha on the general factor (0.78) and on the group factor spinal-plus (0.74) were satisfying. Cronbach’s alpha on the group factors mental (0.56) and bulbar (0.48) were low. Reliability based on CIFA was 0.85. Conclusion: Results showed a clear factor structure of the GNDS. It justifies the use of the total score of the GNDS. In addition, three sub-scale scores could be used.

Abstract Introduction Background: The assessment of sex addiction among different populations requires a valid and reliable tool. Since the Bergen–Yale Sex Addiction Scale (BYSAS) was not available in Iran, this study aimed to evaluate the validity and reliability of the Persian version of the BYSAS. Method: After translation/back-translation procedure, a total of 756 Iranian men and women completed the BYSAS. The structural validity of this tool was evaluated by exploratory and confirmatory factor analyses. An expert panel review also examined content validity of the items. Psychometric properties of the scale including validity, reliability (internal consistency [Cronbach’s alpha]) and test-retest) and factor structure were assessed. Results: Content Validity Index (CVI) and Content Validity Ratio (CVR) scores for the BYSAS were 0.75 and 0.62, respectively. In the measure's structural validity, the results of exploratory and confirmatory factor analysis supported the One-factor structure. Data analysis demonstrated satisfactory internal consistency (Cronbach’s alpha ranging from 0.88 to 0.89). Discussion: Study findings suggest that the BYSAS is a valid and reliable instrument for assessing sex addiction among Persian speaking adults. Replication of research findings is needed to expand the BYSAS for clinical and non-clinical Iranian populations.

Multigroup Ethnic Identity Measure

The current study examined psychometric properties of the Japanese version of Abbreviated Multidimensional Acculturation Scale (AMAS-ZABB-JP) and the 20-item Multigroup Ethnic Identity Measure (MEIM-JP) with 273 Japanese sojourners and immigrants to the United States. The theoretical six-factor structure for the AMAS-JP and two-factor structure for the MEIM-JP was consistent with the literature. The subscales of the AMAS and MEIM showed expected patterns of correlation with each other and with additional variables (i.e., number of years in the United States), providing evidence for construct validity. Cronbach’s alpha reflected high levels of reliability for both scales. Despite strong psychometric findings, there were translational and cultural-based findings that suggest the need for further research.

Simulation Evaluation

Background and objective: Globally, the use of clinical simulation has been incorporated in different nursing programs. It is important to evaluate simulation using reliable and valid instruments. Using the same instrument helps to evaluate simulation under the same criteria both nationally and internationally. The National League of Nursing developed three simulation scales which is widely used in different countries and demonstrates a good reliability and validity. Nevertheless, it is only available in English. The aim of the study was to translate the original NLN simulation evaluation scales into Traditional Chinese and evaluate its psychometric properties.Methods: Beaton and colleague’s (2000) cross-cultural adaptation guidelines was adopted. Cronbach’s alpha coefficient (α) and Corrected item-total correlation was used to determine the internal reliability. Haccoun’s single group technique was used to assess the equivalent of the scale in the original and the translated version. Lastly, Exploratory Factor Analysis (EFA) was used to determine the factor structure and Intra-Class Correlation Coefficient (ICC) to test the stability of translated scale.Results: Nine simulation experts from Hong Kong, Mainland China, Singapore and Taiwan confirmed translation of the NLN scales (EPQ-C, SDS-C, SSCL-C). Cronbach’s alpha of all subscales and overall scales were acceptable (0.72-0.89). The intra-language, inter-language and temporal inter-language cross correlations between the original and translated scales were correlated (p < 0.01). ICC of the translated scales ranges from good to excellent (0.78-0.91). Lastly, EFA also demonstrated the items were theoretically coherent (≥ 0.40) and have the same factor structure as the original English version.Conclusions: Traditional Chinese NLN simulation evaluation scales demonstrated strong validity and reliability.

Introduction: Since the development of the 10 item Purdue Pharmacist Directive Guidance (PPDG) Scale several studies of the psychometric properties of the PPDG have been conducted. Although Cronbach's alpha was calculated as a means of internal consistency reliability, a demonstration of the mean centering of the individual items from the instrument were not explored. Objectives: This study focused on investigating the mean stabilization of items within the PPDG as they pertain to Cronbach's reliability coefficient calculation. Methods: Using item analysis procedures in SPSS, the mean stability of items within the general factor of directive guidance and subscales of instruction and feedback and goal setting were examined for the PPDG. Results: Mean stability scores for entire PPDG scale and the subscales of instruction and feedback and goal setting were strong. Also, corrected item-total correlations and Cronbach's alphas following item deletion were good for the overall PPDG scale and the subscales. Conclusions: The results provide evidence to enhance understanding of the psychometric stability of the PPDG scale and its subscales.   Type: Original Research

Mobbing has been recognized as a psychosocial risk to the mental health of employees, but also as an organizational problem that has been the object of attention among scholars in sociological, psychological, medical, and criminologist sciences. This study is the preparatory phase of the implementation of The Negative Acts Questionnaire-Revised (NAQ-R, Einarsen, Hoel and Notelaers, 2009)which tests for exposure to harassment in the workplace. The main aim of the study was to determine whether the instruments are applicable to the sample of Croatian employees, by means of testing the factor structure and internal reliability of the said questionnaire. The sample encompassed 209 police officers of both genders in the Split-Dalmatia Police District, and the data were acquired by means of a survey. We used descriptive statistics to show the characteristics of the sample and to analyse the findings, and we tested the factor structure by utilizing principal factor analysis, relying on the Kaiser-Guttman criterion. We tested the internal reliability of the sample with the Cronbach’s Alpha coefficient. The results suggest that there is a two-factor structure in the questionnaire, with the first factor referring to harassment aimed at the employee’s personality, and the second factor referring to harassment that is aimed at the employee’s work. Cronbach’s Alpha coefficient shows a high level of reliability (α = 0.959).

This study used exploratory factor analysis to test the factor structure of the Project for Educational Research That Scales (PERTS) instrument. Research that reports the reliability, construct validity, and factor structure of the PERTS scale is useful for interpreting the results from the use of the widely distributed survey and for suggesting interventions to develop an academic mindset in the classroom. Correlations and exploratory factor analyses were performed using pre-existing data from a medium-sized, rural school district, in a large southwestern state of the U.S. as self-reports from a sample of 2,908 students, in grades 3 through 8, at three elementary and two middle schools. Results of the exploratory factor analysis confirmed the proposed four-factor structure. The PERTS survey demonstrated internal reliability on three of the four scales above the pre-determined indices of Cronbach’s alpha > .80, with the exception of the individual mindset scale with a Cronbach’s alpha of .772.
