Factorial Structure and Psychometric Properties of the Sensation Seeking Scale – Form V (SSS-V) in a Sample of Italian Adolescents
2013
The present study was designed to evaluate the psychometric properties of the Sensation Seeking Scale – Form V (SSS-V) for the Italian-speaking population. The instrument was administered to 1,530 high school and college students. A second group of 268 high school students completed the SSS-V and the Impulsiveness Questionnaire (IVE). Exploratory factor analysis highlighted a 2-factor structure, Thrill and Adventure Seeking (TAS) and Disinhibition (Dis). Confirmatory factor analysis revealed an adequate model fit. Internal consistency of the subscales was marginally supported using the alpha reliability measure. Convergent validity was supported by significant positive correlations between …
Validation of the German Version of the Music-Empathizing-Music-Systemizing (MEMS) Inventory (Short Version)
2018
Background: Kreutz et al. (2008) developed the Music-Empathizing-Music-Systemizing (ME-MS) Inventory to extend Baron-Cohen's cognitive style theory to the domain of music. We sought to confirm the ME-MS construct in a German sample and to explore these individual differences in relation to music preferences. Methods: The German adaptation of the MEMS Inventory was achieved by forward and backward translation. A total of 1014 participants (532 male, age: 33.79 ± 11.89 years) completed the 18-item short version of the MEMS Inventory online. Confirmatory factor analysis (CFA) was performed and cut-off values were established to identify individuals who could be classified as ME, Balanced, or M…
Development and Psychometric Validation of the Brief Nurses' Practice Environment Scale and Its Relation to Burnout Syndrome and Job Satisfaction: A …
2020
Introduction: Nursing environment is a vast concept that traditionally has included a wide range of job characteristics and has been related to burnout and job satisfaction. For its measurement, the Practice Environment Scale of the Nursing Work Index (PESNWI) stands out. However, shorter instruments are needed. The purpose of the study is to develop and test the Brief Nurses' Practice Environment (BNPE) Scale.Methods: The BNPE Scale was developed and tested in a sample of 210 Spanish nurses (data collection 2018).Results: Cronbach's alpha was 0.702. The confirmatory factor analysis (CFA), with an excellent fit, offered evidence of internal validity. Regarding validity, the BNPE Scale predi…
APROXIMACIÓN CONCEPTUAL Y PRÁCTICA A LOS MODELOS DE ECUACIONES ESTRUCTURALES
2017
En el presente trabajo se expone una aproximación conceptual y práctica a los Modelos de Ecuaciones Estructurales o Structural Equation Modeling (SEM). Los SEM están considerados entre las herramientas más potentes para el estudio de relaciones causales en datos no experimentales. Son una combinación del análisis factorial y la regresión múltiple y están compuestos por dos componentes: el modelo de medida y el modelo estructural. El modelo de medida describe la relación existente entre una serie de variables observables; mientras que en el modelo estructural se especifican las relaciones hipotetizadas entre las variables, es decir, se describen las relaciones entre las variables latentes me…
Capturing the Severity and Impairment Associated With Depression: The Overall Depression Severity and Impairment Scale (ODSIS) Validation in a Spanis…
2019
Background: The Overall Depression Severity and Impairment Scale (ODSIS) is a self-report scale designed to evaluate the severity and functional impairment associated with depression. Objective: This study evaluated the psychometric properties of the online version of the ODSIS in Spanish outpatients with depression and anxiety disorders. Method: Patients with a main diagnosis of a depressive (n = 283) or anxiety disorder (n = 191) and a mean age of 38.15 (SD = 12.06) were evaluated with a clinical diagnostic interview and measures assessing depression, anxiety, positive and negative affect, and quality of life. Factorial structure, internal consistency, convergent, and discriminant validit…
Measuring pre-service teachers' attitudes towards inclusive education: Psychometric properties of the TAIS scale
2015
The Teachers’ Attitudes towards Inclusive Education (TAIS) scale was designed to measure pre-service teachers’ attitudes towards inclusion, as defined in the Salamanca Statement of UNESCO. The 10-item scale was developed using a sample of 185 final-year pre-service subject teachers. It was validated in four subsequent studies with various samples of teachers and pre-service teachers. The unidimensionality of the scale was established in all samples except the first-year students, and its validity was confirmed in psychometric analyses. The scale is suggested for use in intervention studies aiming to develop positive attitudes towards inclusion among teachers and pre-service teachers. peerRe…
Couches minces d'oxynitrure de titane : la réactivité comme moyen original de caractérisation physico - chimique
2002
Titanium oxinitride thin films, TiNxOy, were elaborated on Si(100) by the MOCVD (Metal Organic Chemical Vapor Deposition) method, using titanium isopropoxide Ti(OCH(CH3)2)4 and ammonia NH3 as precursors. By varying the growth temperature, it is possible to modify the N/O ratio and change the conductivity of the films.The target of this work was to determine the composition and the structure of these TiNxOy thin films in order to understand the electrical properties. However, this study was difficult because classical characterization techniques (SEM, XRD, Raman, XPS...) were unable to describe the whole TiNxOy system. Indeed, only a structure which is isomorphic to TiN (NaCl structure) was …
Are Happy Workers More Productive? The Mediating Role of Service-Skill Use
2020
The purpose of this paper is to examine the relationship between happiness at work and cross-selling performance in the banking sector. In addition, the mediating effect of service-skill use is analyzed in the relationship between happiness at work and performance. Confirmatory factor analysis is used by means of structural equation models to assess the relationship between happiness at work, service-skill use, and cross-selling performance. A sample of 492 financial service employees is examined. Results reveal that happiness at work positively and directly affects cross-selling performance. The study also shows that service-skill use plays a partial mediating role in the relationship betw…
Detecting Authoritarianism Efficiently: Psychometric Properties of the Screening Instrument Authoritarianism – Ultra Short (A-US) in a German Represe…
2020
With right-wing-extremist and -populist parties and movements on the rise throughout the world, the concept of authoritarianism has proven to be particularly valuable to explain the psychological underpinnings of these tendencies. Even though many scales to measure the different dimensions of authoritarianism exist, no short screening instrument has been tested and validated on a large scale so far. The present study examines the psychometric properties of the screening instrument Authoritarianism ��� Ultrashort (A-US) in three representative German samples (n = 2,524, n = 2,478, and n = 2,495). Using exploratory and confirmatory factor analysis, the A-US demonstrated acceptable internal co…
Psychosocial Work Factors, Job Stress and Strain at the Wheel: Validation of the Copenhagen Psychosocial Questionnaire (COPSOQ) in Professional Drive…
2019
Introduction: Psychosocial work environment has been related to many negative health outcomes in different workforces. However, evidence in this regard is still limited in the case of transport workers, and most of the tools used in research, often excessively generic, do not fully consider the specific key stressors and adverse issues present in the psychosocial environment of professional driving. Objective: Thus, the purpose of this study was to obtain a complete description of the validation of measurement applied to psychosocial factors at work in professional drivers, using the Enterprise version (2018) of COPSOQ-III. Methods: The data was collected from 726 Spanish professional drive…
