Background/Objective: The Life Orientation Test-Revised (LOT-R) is often used to assess dispositional optimism. The aims of this study were to test psychometric properties of the LOT-R, to provide normative scores, and to test the association between optimism and several psychological, sociodemographic, and behavioral factors. Method: A randomly selected German general population community sample with an age range of 18-80 years (N = 9,711) was surveyed. Results: The Confirmatory Factor Analysis (CFA) proved two (correlated) factors: Optimism and Pessimism. Invariance tests across gender and age groups confirmed metric invariance. There were only small gender differences in the LOT-R total …

The Italian Version of the Inventory of Interpersonal Problems (IIP-32): Psychometric Properties and Factor Structure in Clinical and Non-clinical Gr…

2018

All versions of the Inventory of Interpersonal Problems (IIP) are broadly used to measure people's interpersonal functioning. The aims of the current study are: (a) to examine the psychometric properties and factor structure of the Italian version of the Inventory of Interpersonal Problems-short version (IIP-32); and (b) to evaluate its associations with core symptoms of different eating disorders. One thousand two hundred and twenty three participants (n = 623 non-clinical and n = 600 clinical participants with eating disorders and obesity) filled out the Inventory of Interpersonal Problems-short version (IIP-32) along with measures of self-esteem (Rosenberg Self-Esteem Scale, RSES), psych…

Development and Validation of the Test of Orthorexia Nervosa (TON-17)

2021

This study aims to develop and validate a new self-report questionnaire to measure orthorexia nervosa (ON). Based on a current review of the scientific literature and interviews with people at risk of orthorexia, 40 items were selected to test orthorexia nervosa (TON-40). A total sample of 767 individuals (M = 26.49, SD = 9.66, 56.98% women) participated in the study. The exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and composite construct analysis (CCA) were performed to find an appropriate model of sufficient reliability and validity and stable construction. Convergent validation was performed regarding the correlation of the TON-17 with another measure of ON (OR…

Expert In-depth Interview on Development and Efficiency of “RIGA International Airport” Reflecting Factors

2016

Abstract The aim of the paper is to identify development ways and effectiveness of RIGA International Airport. Theoretical evidence was examined and expert in-depth interview was carried out to explore the main circumstances affecting RIGA International Airport functioning. Findings of the study show that there are positive tendencies in the field of airport efficiency and development, but improvement is needed primarily for coordinating visions and resources managed by both state and airport administration bodies.

Assessing the factor structure of the Behaviour of Young Novice Drivers Scale (BYNDS)

2020

Abstract The Behaviour of Young Novice Drivers Scale (BYNDS) is a self-report instrument to assess risky driving behaviours among youth population. Although previous studies have offered evidences of reliability and validity for the BYNDS scores, results are not conclusive as regards its factor structure. The aim of this research was to assess the factor structure of the BYNDS via Confirmatory Factor Analyses (CFA). The BYNDS was administered to a sample of 832 drivers aged from 18 to 25 years (Argentina = 270, Colombia = 350, and Mexico = 212). Six models were examined: three derived from previous literature, one emerged from an exploratory factor analysis, a unidimensional model, and a bi…

Orientation-invariance of individual differences in three face processing tasks

2019

Numerous studies have reported impairments in perception and recognition, and, particularly, in part-integration of faces following picture-plane inversion. Whether these findings support the notion that inversion changes face processing qualitatively remains a topic of debate. To examine whether associations and dissociations of the human face processing ability depend on stimulus orientation, we measured face recognition with the Cambridge Face Memory Test (CFMT), along with experimental tests of face perception and selective attention to faces and non-face objects in a sample of 314 participants. Results showed strong inversion effects for all face-related tasks, and modest ones for non-…

El Análisis Factorial Exploratorio de los Ítems: una guía práctica, revisada y actualizada

2014

El Análisis Factorial Exploratorio es una de las técnicas más usadas en el desarrollo, validación y adaptación de instrumentos de medida psicológicos. Su uso se extendió durante los años 60 y ha ido creciendo de forma exponencial al ritmo que el avance de la informática ha permitido. Los criterios empleados en su uso, como es natural, también han evolucionado. Pero los investigadores interesados en asuntos sustantivos que utilizan rutinariamente esta técnica permanecen en muchos casos ignorantes de todo ello. En las últimas décadas numerosos trabajos han denunciado esta situación. La necesidad de actualizar los criterios clásicos para incorporar aquellos más adecuados es una necesidad urgen…

Desarrollo y validación del Cuestionario de Personalidad Vocacio-nal Adaptativa: un cuestionario para analizar la conducta vocacional de estudiantes …

2013

This study presents a personality evaluation instrument adapted to the vocational setting: the Adaptive Vocational Personality Questionnaire (AVPQ). The questionnaire was developed and tested in a sample of 2160 university students in the final years of their degree programs. The purpose of the study is to validate the questionnaire, providing evidence about its internal structure and its usefulness for predicting scores on a criterion scale. A confirmatory factor analysis combined with a cross-validation design was used: the exploratory sample (n = 879) helped to identify the model with the factorial structure that best fit the relations among the items. As expected, this model had two rel…

Development of a Brief Form of the Interpersonal Reactivity Index (B–IRI)

2016

ABSTRACTThe Interpersonal Reactivity Index (IRI) is a standardized self-report measure of disposition to empathic responsiveness for the general adult population (the domain for which it was developed), and for the general adolescent population. The IRI has a number of problems, however, including some uncertainty about its factor structure, low reliabilities, and poor readability of some items for people with limited literacy skills. To address these issues, we constructed an abbreviated form of the index, the Brief IRI (B–IRI). Three studies demonstrated that this 16-item B–IRI has a clear and coherent factor structure, adequate internal consistency, measurement invariance across gender a…

Psychometric evaluations of the Life Orientation Test-Revised (LOT-R), based on nine samples

2021

The aim of this study was to examine psychometric properties of the Life Orientation Test-Revised (LOT-R).The LOT-R was administered in five clinical samples, three samples of the adult general population, and one sample of adolescents. Seven of the studies were performed in Germany and two in Colombia. All of the sample sizes were above 300.Cronbach's alpha coefficients were between .57 and .75 for the eight adult samples, the correlations between the scales optimism and pessimism ranged from -.05 to -.37, and the coefficients of temporal stability (test-retest correlations) of the scales ranged from .43 to .69. There were no systematic age and gender effects observed in the nine studies. …
