A Monte Carlo study comparing PIV, ULS and DWLS in the estimation of dichotomous confirmatory factor analysis

2012

We conducted a Monte Carlo study to investigate the performance of the polychoric instrumental variable estimator (PIV) in comparison to unweighted least squares (ULS) and diagonally weighted least squares (DWLS) in the estimation of a confirmatory factor analysis model with dichotomous indicators. The simulation involved 144 conditions (1,000 replications per condition) that were defined by a combination of (a) two types of latent factor models, (b) four sample sizes (100, 250, 500, 1,000), (c) three factor loadings (low, moderate, strong), (d) three levels of non-normality (normal, moderately, and extremely non-normal), and (e) whether the factor model was correctly specified or misspecif…

STATIS and DISTATIS: optimum multitable principal component analysis and three way metric multidimensional scaling

2012

STATIS is an extension of principal component analysis PCA tailored to handle multiple data tables that measure sets of variables collected on the same observations, or, alternatively, as in a variant called dual-STATIS, multiple data tables where the same variables are measured on different sets of observations. STATIS proceeds in two steps: First it analyzes the between data table similarity structure and derives from this analysis an optimal set of weights that are used to compute a linear combination of the data tables called the compromise that best represents the information common to the different data tables; Second, the PCA of this compromise gives an optimal map of the observation…

The theme park experience: An analysis of pleasure, arousal and satisfaction

2005

Abstract This article analyses how visitor emotions in a theme park environment influence satisfaction and behavioural intentions. Emotions consist of two independent dimensions, i.e. pleasure and arousal. Two competing models were tested. The first model is derived from the environmental psychology research stream as developed by (An Approach to Environmental Psychology, MIT Press, Cambridge, 1974), where the visitor's arousal generates pleasure and, in turn, approach/avoidance behaviour. This emotion-cognition model is supported by Zajonc and Markus (1984). The second model to be tested is based on Lazarus’ (Emotion and Adaptation, Oxford University Press, New York, 1991) cognitive theory…

Revista electrónica de investigación y evaluación educativa

2010

Este trabajo tiene el propósito de mostrar el uso de la metodología de Modelos de Ecuaciones Estructurales (SEM) para validar la estructura conceptual de cuestionarios de contexto que se utilizan en los estudios nacionales e internacionales para evaluar el logro educativo de los escolares. Desgraciadamente, los organismos evaluadores no destinan los mismos recursos técnicos a los cuestionarios de contexto que a las pruebas de aprendizaje, por lo que rara vez los primeros son sujetos a estudios de validez. Para mostrar el uso de la metodología SEM, se seleccionó el cuestionario dirigido a alumnos que utilizó el Instituto Nacional para la Evaluación de la Educación (INEE) para conocer los fac…

Psychometric properties of the Spanish version of the Temporal Satisfaction with Life Scale (TSLS): A study on elderly attending to university progra…

2015

Several measures have been developed for the operalization of well-being, standing out the Satisfaction With Life Scale (SWLS). To cope with some of its problems the Temporal Satisfaction with Life Scale (TSLS) was developed. The aim of this study is to present and validate the Spanish version of the TSLS, in a sample elderly attending to University programs. The sample was composed of 737 elderly. Together with the TSLS, an indicator of general life satisfaction and the SF-8 Health Scale were used. Analyses included the study of factorial validity, estimations of reliability and external validity. Results of the confirmatory factor analysis were adequate: χ2(87)=454.593 (p<.001), CFI=.9…

The SCIA Questionnaire: standards for communities for children and adolescents – a tool for the evaluation of good practices

2019

Purpose The purpose of this paper is to present the Italian validation of the standards for communities for children and adolescents (SCIA) Questionnaire, an evaluation tool of communities quality standards, based on the “Service Standards for Therapeutic Communities for Children and Young People – 2nd edition” of the Community of Communities (2009), that enables an empirical, multidimensional and complex evaluation of the therapeutic community (TC) “system”. It is a self-report that sets out and measures variables that allow to get an overview of organisational models and the possible development areas to improve the effectiveness of the protection of child and adolescents in community tr…

Assessing teacher leadership in physical education: the Spanish version of the transformational teaching questionnaire

2018

<p>Drawing from the transformational leadership theory, this study aims to translate and analyse the psychometric properties of a Spanish version of the Transformational Teaching Questionnaire (TTQ).</p><p>A cohort sample of 2107 adolescents (997 males and 1110 females) from 82 secondary schools voluntarily participated in the research.</p><p>In Study 1 ((<em>n</em> = 1066), the exploratory factor analysis informed a one-factor solution. In Study 2  (<em>n</em> = 1041), the confirmatory factor analysis showed the single-factor and the four-factor models showed satisfactory and adequate goodness of fit indices, respectively. Confirmatory …

Information assets: A typology of disclosed and non-disclosed information

2020

Abstract The debate surrounding the value of disclosed and non-disclosed information as a competitive element has stalled; it has not been possible to make a universal, precise claim as to their potential to generate competitive advantages. This empirical inconsistency can be explained in part by the heterogeneity of information assets, which can give rise to different information dimensions, each offering different potential for generating results depending on the degree to which they meet the conditions of complementarity and co-specialization with other resources. This article helps to move forward on this issue by presenting a theoretical construct of the concept “information assets" an…
