Spanish validation of the Servant Leadership Short Scale for young adults and adolescents / Validación de la Escala de Liderazgo de Servicio Versión …

2017

AbstractThe aim of the current study was to validate a shortened Spanish version of the Servant Leadership Profile (SLP). In Study 1, a number of experts evaluated and reduced the original scale to 14 items and named the revised version the Servant Leadership Short Scale (SLSS). An exploratory factor analysis conducted with a sample of 1,001 students revealed two possible structure solutions, a one-factor solution and a two-correlated factor solution. Study 2 used a different sample of 456 students to examine the explored structures using confirmatory factor analysis. A one-factor solution was proposed (χ2/df = 3.4, CFI = .91, TLI = .90, RMSEA = .07, SRMR = .06). Finally, in Study 3, servan…

Et si nous arrêtions d'utiliser systématiquement l’analyse en composantes principales (PCA)? Efficacité des méthodes d’extraction de facteurs dans l’…

2014

Fabrigar et al. (1999) et, en suite Worthington et Whittaker (2006) décrivaient les limites de l’utilisation de la PCA comme méthode d’extraction de facteurs dans les procédures d’EFA. Les auteurs soulignent que l’abus de cette pratique s’explique probablement par le fait que cette méthode est présentée comme premier choix dans la plupart des logiciels d’analyse des données. L’objectif de ce travail est de montrer qu’il y a encore un excès d’utilisation dans la pratique de la PCA et, de l’autre, de donner des indications de base pour le choix d’une méthode correcte pour l’EFA. Ce travail recense les principaux travaux de recherche parus, entre 2011 et 2013, dans des revues à facteur d'impac…

A Survey of Teacher Perceptions of the School Psychologist's Skills in the Consultation Process An Exploratory Factor Analysis

2004

The main purpose of this study is to present the construction and validation process of an instrument designed to evaluate the professional skills of the school psychologist in the teacher consultation process. Initially, an extensive list of items was created which evaluated the characteristics of school psychologists in this area. After carrying out a pilot study and making the necessary modi.cations, we presented the scale to a sample of 157 primary and secondary public school teachers in the Valencian Community. An exploratory factor analysis was carried out on the main components, applying the corresponding varimax rotation. The results show a factorial structure made up of three comp…

Introduction and Psychometric Validation of the Resilience and Strain Questionnaire (ResQ-Care)— A Scale on the Ratio of Informal Caregivers' Resilie…

2021

Background: Informal caregivers are a particularly vulnerable population at risk for adverse health outcomes. Likewise, there are many scales available assessing individual caregiver burden and stress. Recently, resilience in caregivers gained increasing interest and scales started to assess resilience factors as well. Drawing on a homeostatic model, we developed a scale assessing both caregivers' stress and resilience factors. We propose four scales, two covering stress and two covering resilience factors, in addition to a sociodemographic basic scale. Based on the stress:resilience ratio, the individual risk of adverse health outcomes and suggestions for interventions can be derived.Metho…

Smartphone Addiction Inventory (SPAI): Psychometric properties and confirmatory factor analysis

2016

The Smartphone Addiction Inventory (SPAI) was developed to assess smartphone addiction in Taiwanese university students. The purpose of the current research is to evaluate the factor structure and psychometric properties of the SPAI in Italian university students. A total of 485 university students (29.3% boys) completed the SPAI and the Young's Internet Addiction Test (IAT).The proposed four-factor model of the SPAI-I was tested by computing CFA, and the results of the goodness of fit indices indicated an ambiguous solution. An exploratory-confirmatory cross validation strategy was applied for a better trimming of SPAI-I factorial structure. Results suggested a five-factor solution that ex…

Transcultural adaptation and validation of the spanish version of the sexual satisfaction scale for women (SSS-W-E)

2021

Background: Sexual satisfaction is a complex and multidimensional concept. It encompasses physical, emotional, relational and cultural dimensions, and constitutes an essential component of sexual health, as well as an indicator of quality of life and wellbeing. The Sexual Satisfaction Scale for Women (SSS-W) was designed in the United States, and it is a valid and reliable tool to measure women’s sexual satisfaction. Aim: The aim of this study was to culturally adapt and translate the SSS-W into Spanish and analyze its psychometric properties. Methods: First, the original instrument was culturally adapted and translated from English to Spanish. Then, we tested the psychometric properties of…

Factorial Validity and Reliability of the Curricular Goals in Physical Education Questionnaire

2015

This study aimed to examine the validity and reliability of an instrument designed to measure student perceptions of curricular goals in physical education, the Curricular Goals in Physical Education Questionnaire. Participants were 879 Finnish students from grades 7 to 9 (412 girls, 467 boys; mean age 13.81). An exploratory factor analysis was performed on Sample 1 (n = 287), revealing a four-factor solution and suggesting that factor structure be cross-validated with confirmatory factor analysis in Sample 2 (n = 592). Confirmatory factor analysis demonstrated an acceptable fit and supported the four-factor model. Tests for gender invariance supported configural, metric, and scalar invaria…

CAT score single item analysis in patients with COPD: results from COSYCONET

2019

Abstract The COPD Assessment Test (CAT) is in widespread use for the evaluation of patients with chronic obstructive pulmonary disease (COPD). We assessed whether the CAT items carry additional information beyond the sum score regarding COPD characteristics including emphysema. Patients of GOLD grades 1 to 4 from the COPD cohort COSYCONET (German COPD and Systemic Consequences - Comorbidities Network) with complete CAT data were included (n = 2270), of whom 493 had chest CT evaluated for the presence of emphysema. Comorbidities and lung function were assessed following standardised procedures. Cross-sectional data analysis was based on multiple regression analysis of the single CAT items ag…

Dimensionality and factorial invariance of religiosity among Christians and the religiously unaffiliated: A cross-cultural analysis based on the Inte…

2019

We present a study of the dimensionality and factorial invariance of religiosity for 26 countries with a Christian heritage, based on the 1998 and 2008 rounds of the International Social Survey Programme (ISSP) Religion survey, using both exploratory and multi-group confirmatory factor analyses. The results of the exploratory factor analysis showed that three factors, common to Christian and religiously unaffiliated respondents, could be extracted from our initially selected items and suggested the testing of four different three-factor models using multi-group confirmatory factor analysis. For the model with the best fit and measurement invariance properties, we labeled the three resulting…
