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…
Separation of Cognitive Impairments in Attention-Deficit/Hyperactivity Disorder Into 2 Familial Factors
2010
Contains fulltext : 89304.pdf (Publisher’s version ) (Open Access) CONTEXT: Attention-deficit/hyperactivity disorder (ADHD) is associated with widespread cognitive impairments, but it is not known whether the apparent multiple impairments share etiological roots or separate etiological pathways exist. A better understanding of the etiological pathways is important for the development of targeted interventions and for identification of suitable intermediate phenotypes for molecular genetic investigations. OBJECTIVES: To determine, by using a multivariate familial factor analysis approach, whether 1 or more familial factors underlie the slow and variable reaction times, impaired response inhi…
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…
Spanish validation of the PICCOLO (Parenting Interactions With Children: Checklist of Observations Linked to Outcomes)
2019
Background/Objective: The aim of this study was to explore the psychometric properties of the Spanish version of the Parenting Interactions with Children: Checklist of Observations Linked to Outcomes (PICCOLO; Roggman et al., 2013a). This observational measure is composed of 29 items that assess the quality of four domains of parenting interactions that promote child development: affection, responsiveness, encouragement, and teaching. Methods: The sample included 203 mother-child dyads who had been video-recorded playing together. Fifty-six percent of the children were male, and 44% were female, aged from 10 to 47 months. Video-recorded observations were rated using PICCOLO items. Results: …

Willingness to Donate Organs After Death
2023
Abstract: Background: Despite the growing number of organ transplants, there is still a significant difference between the number of donated organs and the number of people waiting for them. Knowing the reason people decide to donate is the first step to increasing organ donation rates. Aims: The main aim of the present study was to develop and validate a new scale for organ donation. Method: In three studies, 3,585 participants ranging in age between 14 and 89 years were selected through systematic random sampling. In the first study, we created a scale following the organ donation model theoretical framework and submitted the scale to exploratory factor analysis. In the second study, we …
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…
