Shift- and scale-invariant recognition of contour objects with logarithmic radial harmonic filters.

2008

The phase-only logarithmic radial harmonic (LRH) filter has been shown to be suitable for scale-invariant block object recognition. However, an important set of objects is the collection of contour functions that results from a digital edge extraction of the original block objects. These contour functions have a constant width that is independent of the scale of the original object. Therefore, since the energy of the contour objects decreases more slowly with the scale factor than does the energy of the block objects, the phase-only LRH filter has difficulties in the recognition tasks when these contour objects are used. We propose a modified LRH filter that permits the realization of a shi…

Rumination for innovation? : analyzing the longitudinal effects of work-related rumination on creativity at work and off-job recovery

2017

ABSTRACTWork-related rumination is not a single construct, but consists of a dimension associated with negative emotions or affect (affective rumination), and a dimension associated with reflective thinking and applying strategies to solve problems (problem-solving pondering). In this three-wave longitudinal study across two years (N = 630) we investigated whether the relationships between work-related rumination, off-job recovery, and creativity at work varied along the two dimensions of work-related rumination. In addition, we tested whether the relationships followed normal, reversed, or reciprocal causation. The results showed, first, that in a one-year perspective affective rumination,…

Factor Structure and Measurement Invariance Across Gender Groups of the 15-Item Geriatric Depression Scale Among Chinese Elders

2019

The 15-item Geriatric Depression Scale (GDS-15) is widely used to screen depression among elders. But the factor structure of the Chinese version GDS-15 remains unclear. This study was conducted to determine the best-fit factor structure of GDS-15 and to assess measurement invariance across gender groups in a sample of Chinese elders recruited from Mainland China (final sample N = 2428). The best-fit factor structure was examined by confirmatory factor analysis (CFA). Multigroup CFA was utilized to test the measurement invariance across genders of the factor structure. The results of CFA revealed that a three-factor model, including life satisfaction (four items), general depressive affect …

A cross-country examination of emotional eating, restrained eating and intuitive eating: Measurement Invariance across eight countries

2020

This study examined the measurement invariance of three scales that assessed emotional eating, restrained eating, and intuitive eating across eight countries (Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States) in order to determine their suitability for cross-country body image research. A total of 6272 young adults took part in this study. Participants completed an online survey including the Emotional Eating subscale of the Three Factor Eating Questionnaire-Revised 21, the Restraint subscale of the Eating Disorder Examination Questionnaire, and the Reliance on Hunger and Satiety Cues subscale of The Intuitive Eating Scale-2. Multi-group confirmatory factor analy…

Bryant's Empathy Index: Structure and Measurement Invariance across Gender in a Sample of Primary School-Aged Children.

2016

AbstractThe purpose of this study was to examine the dimensional structure and measurement invariance of Bryant’s Index of Empathy for Children and Adolescents (IECA) (Bryant, 1982) across gender in a representative sample of primary school-aged children in Spain. The sample consisted of 2,050 children (50.80% girls), with a mean age of 9.80 years (SD = 1.24), recruited from 27 primary schools. Exploratory and confirmatory factor analyses were conducted. The model that presented the best fit indices was Lasa, Holgado, Carrasco, and del Barrio’s (2008) three-factor model: Understanding Feelings, Feelings of Sadness, and Tearful Reaction. The levels of internal consistency for the subscales r…

Adaptation of the Participant Role Scale (PRS) in a Spanish Youth Sample

2014

In recent years, bullying research has transitioned from investigating the characteristics of the bully–victim dyad to examining bullying as a group-level process, in which the majority of children play some kind of role. This study used a shortened adaptation of the Participant Role Scale (PRS) to identify these roles in a representative sample of 2,050 Spanish children aged 8 to 13 years. Confirmatory factor analysis revealed three different roles, indicating that the adapted scale remains a reliable way to distinguish the Bully, Defender, and Outsider roles. In addition, measurement invariance of the adapted scale was examined to analyze possible gender differences among the roles. Peer…

FACTORIAL INVARIANCE OF PERSONALITY RATINGS

1969

Kuusinen, J. Factorial invariance of personality ratings. Scand. J. Psychol., 1969, 10, 33–44—Three studies employing the same set of 33 personality rating scales are described. (I) Five factor structures of the scales, derived from ratings of five groups of stimuli, were compared. (2) One subject rated different personality concepts three times at one week's intervals. (3) 12 individual factor structures were compared to the factor structure computed from peer ratings of a group of 39 subjects. Results: (a) the factor structure of the scales was largely independent of stimuli, (b) the structure for an individual was stable, (c) the group structure represented the individual's structure, (d…

Association between Actual and Perceived Motor Competence in School Children

2020

(1) Background: The association between actual and perceived motor competence (MC) is one of the underlying mechanisms that influence the practice of physical activity. This study mainly aimed to analyze the structure and correlations between actual and perceived MC in schoolchildren and to compare actual and perceived MC between girls and boys. (2) Methods: A total of 467 fifth and sixth graders (43.9% girls, M = 11.26, SD = 0.70) participated. Actual and perceived MC were assessed. To examine the proposed four factor models, structural equation models (factor analyses, latent correlations, invariance testing for gender) were conducted. Student t-test for independent samples was used to co…

Researching Parental Socialization Styles across Three Cultural Contexts: Scale ESPA29 Bi-Dimensional Validity in Spain, Portugal, and Brazil

2019

Recent research that relates parenting with adolescent adjustment has shown the importance of considering the cultural context of the relationship. New results are emerging when considering the classical four-typologies model of parental socialization in some European and South-American countries. Among the instruments used in this emergent research is the Parental Socialization Scale ESPA29. This scale is a bi-dimensional parenting instrument that was specifically developed to measure the four parenting typologies, through the dimensions of acceptance/involvement and strictness/imposition. This study examines the good fit of the orthogonal bi-factor model based on the ESPA29 versus one-dim…

Dimensional structure and measurement invariance of the BRIEF-2 across gender in a socially vulnerable sample of primary school-aged children.

2018

The present study aims to analyze, on the one hand, the dimensional structure of the BRIEF-2 and, on the other, its measurement invariance across gender in a sample of primary school-aged children. Participants were 168 students (51.8% girls) in conditions of social risk and in foster homes, with ages ranging from 6 to 15 years old (M = 10.08; SD = 2.09). The children's executive functioning level was obtained from their parents or caregivers. The analysis of the internal structure using confirmatory factor analysis reveals that the model with three indexes (Behavioral, Emotional and Cognitive) and nine scales (Inhibit, Shift, Self-Monitor, Emotional Control, Initiate, Working Memory, Plan/…
