A Confirmatory Factor Analysis of the “Autoconcepto Forma 5” Questionnaire in Young Adults from Spain and Chile
2011
The aim of this work is to examine the pentafactorial validity of the AF5 Self-Concept Questionnaire in Spanish and Chilean young adults. From the responses of a total of 4,383 young adults aged 17 to 22 years (1,918 Spanish, 44%, and 2,465 Chilean, 56%) it was analyzed the reliability of the instrument, the compared validity of the 5 oblique factor model proposed by the authors versus the unifactorial and the orthogonal alternative models, and was studied the invariance of one Chilean sample. The results of confirmatory factor analyses supported the authors' pentafactorial model. The multi-group factorial invariance showed that Chilean sample of the AF5 does not change neither the Spanish …
Psychometric evaluation of the Finnish version of the impact on participation and autonomy questionnaire in persons with multiple sclerosis
2017
Objective: The objective of this study was to evaluate the psychometric properties of the impact on participation and autonomy (IPA) questionnaire. The Finnish version of IPA (IPAFin) was translated into Finnish using the protocol for linguistic validation for patient-reported outcomes instruments. Methods: A total of 194 persons with multiple sclerosis (MS) (mean age 50 years SD 9, 72% female) with moderate to severe disability participated in this study. A confirmatory factor analysis (CFA) was used to confirm the four factor structure of the IPAFin. The work and educational opportunities domain was excluded from analysis, because it was only applicable to 51 persons. Internal consistency…
Compassion Satisfaction, Compassion Fatigue, and Burnout in Spain and Brazil: ProQOL Validation and Cross-cultural Diagnosis
2017
Abstract Context Palliative care professionals' quality of life has emerged as a growing issue of interest in health care literature, centered on concerns about professionals' compassion within a context of work characterized by pain and death. Objectives The aim of this study was threefold: 1) to study the psychometric properties of both the Spanish and the Portuguese versions of the ProQOL scale, by means of confirmatory factor analyses; 2) to offer a diagnosis of compassion satisfaction and compassion fatigue levels of Spanish and Brazilian palliative care professionals; and 3) to compare levels in ProQOL between countries. Methods Two surveys with a cross-sectional design were carried o…
Does the Spanish version of the SWLS measure the same in Spain and Peru?
2019
Aim Satisfaction with life is a measure of protection in older adults. There lies the importance of providing quality instruments. The aim of the study was to evaluate the invariance of the life satisfaction scale (SWLS) in two samples of older adults in Spain and Peru. Method The participants were 857 older adults in Spain (mean age = 68.23 years, SD = 5.93) and 336 older adults in Peru (average age = 72.42, SD = 7.07). All multi-group confirmatory factor analyzes were estimated in Mplus 8.0. Results The results indicate the presence of a strict invariance of the one-dimensional structure of the SWLS in samples of older adults in Spain and Peru, which allows for meaningful comparisons of l…
How students perceive the university's mission in a Spanish university: Liberal versus entrepreneurial education?
2013
AbstractThis study explores the extent to which undergraduate students perceive a dichotomy between a liberal vs. an entrepreneurial model of university. This research is important in that it compares the stated aims of university education, particularly within the Bologna Process, with students' expectations regarding liberal education and employability. A Likert-type questionnaire containing 25 statements reflecting liberal and entrepreneurial features of university education was answered by 488 students from 10 disciplines at the University of Valencia, Spain, just before the implantation of the Bologna curriculum. An exploratory factor analysis revealed that students clearly perceive th…
The Impact of Acculturation on Attitudinal Familism in a Community of Puerto Rican Americans
1998
The goal of this study was to examine the relationship between acculturation and familism in a samnple of 182 Hispanics of Puerto Rican descent. Exploratory factor analysis was used to establish the multidimensionality of each construct. Consistent with earlier studies, three dimensions of acculturation and familism were identified. Each dimension offamilism was then regressed on a set of explanatory variables that included three dimensions of acculturation. For two dimensions offamilism (familial obligations and support from relatives), acculturation was positively related to familism; for the other dimension (family as referents), the relationship was nonsignificant. In explaining varian…
Different facets of attitudes towards having children: The Procreation Attitude Scale (PrAttS)
2020
The attitudes towards children are more complex than simple positive/negative distinctions. In the present study, we sought in two studies (N = 445) to provide a tool to explore different facets of attitudes towards babies and procreation by developing and validating a questionnaire regarding attitudes towards procreation. Study 1 was conducted to develop an English language scale tapping into adults’ attitudes toward having offspring. A larger number of statements were formulated that expressed an emotional value and motivational attitudes towards having babies. The sample consisted of n = 157 participants. Participants’ responses were subjected to a preliminary principal components analys…
Factor analysis of the Spanish Burnout Inventory among public administration employees
2014
Burnout has been recognized as an important stress-related problem. Researchers have been troubled by some of the psychometric limitations of the questionnaires developed to evaluate burnout. This study was designed to assess the factor structure of the Spanish Burnout Inventory in a sample of 548 Brazilian public administration employees. This instrument comprises 20 items distributed in four dimensions: enthusiasm toward the job (5 items), psychological exhaustion (4 items), indolence (6 items), and guilt (5 items). The factor structure was examined through confirmatory factor analysis. To assess the factorial validity of the Spanish Burnout Inventory, four alternative models were tested.…
Tensor decomposition of EEG signals: A brief review
2015
Electroencephalography (EEG) is one fundamental tool for functional brain imaging. EEG signals tend to be represented by a vector or a matrix to facilitate data processing and analysis with generally understood methodologies like time-series analysis, spectral analysis and matrix decomposition. Indeed, EEG signals are often naturally born with more than two modes of time and space, and they can be denoted by a multi-way array called as tensor. This review summarizes the current progress of tensor decomposition of EEG signals with three aspects. The first is about the existing modes and tensors of EEG signals. Second, two fundamental tensor decomposition models, canonical polyadic decomposit…
National collective identity in transitional societies: Salience and relations to life satisfaction for youth in South Africa, Albania, Bulgaria, the…
2017
In this study we investigated the salience of the construct of national collective identity and its associations with life satisfaction among adolescents living in transitional societies characterised by relevant change in the last decades. Participants were 1 066 adolescents (M = 15.35 years, SD = 1.35) from South Africa (n = 186) and five Central Eastern European countries, including Albania (n = 209), Bulgaria (n = 146), Czech Republic (n = 306), Kosovo (n = 116), and Romania (n = 103). They completed a questionnaire including national identity and life satisfaction scales. Data were analysed using confirmatory factor analysis and multi-group structural equation modeling. Results showed …
