Development and Preliminary Italian Validation of the Emergency Response and Psychological Adjustment Scale
2021
Evaluating the personal adaptation response to the emergency situations is very important for the prevention of mental distress, for the activation of network and community synergies and for the planning and implementation of appropriate psycho-social interventions. So far there are no short tools for the overall assessment of cognitive, emotional and behavioral responses of psychological adaptation to the emergency in the psychometric panorama. The Emergency Response and Psychological Adjustment Scale (ERPAS) was administered to a sample of 1,088 participants, while the concurrent validity was tested through a second administration to 600 participants along with the GSE (Generalized Self-E…
The Positivity Scale: Concurrent and Factorial Validity Across Late Childhood and Early Adolescence
2019
Despite the well-established protective functions of positivity (i.e., a dispositional selfevaluative tendency to view oneself, life, and future under a positive outlook) from middle adolescence to old age, its reliable assessment and contribution to a proper psychological functioning have received little attention during previous developmental phases. In this article, we aimed to evaluate the psychometric properties and construct validity of the eight-item Positivity Scale (P Scale; Caprara et al., 2012) during late childhood and early adolescence in a sample of British students (N = 742; 48% boys) from both primary (M age = 10.75, SD = 0.52) and secondary schools (M age = 13.38 years, SD …
Advanced spatio-temporal point processes for the Sicily seismicity analysis
2018
Due to the complexity of the generator process of seismic events, we study under several aspects the interaction structure between earthquake events using recently developed spatio-temporal statistical techniques and models. Using these advanced statistical tools, we aim to characterise the global and local scale cluster behaviour of the Easter Sicily seismicity considering the catalogue data since 2006, when the Italian National Seismic Network was upgraded and earthquake location was sensibly improved. Firstly, we characterise the global complex spatiotemporal interaction structure with the space-time ETAS model where background seismicity is estimated non-parametrically, while triggered …
On hidden heterogeneity in directional asymmetry – can systematic bias be avoided?
2006
8 pages; International audience; Directional asymmetry (DA) biases the analysis of fluctuating asymmetry (FA) mainly because among-individual differences in the predisposition for DA are difficult to detect. However, we argue that systematic bias mainly results from predictable associations between signed right-left asymmetry and other factors, i.e. from systematic variation in DA. We here demonstrate methods to test and correct for this, by analysing bilateral asymmetry in size and shape of an irregular sea urchin. Notably, in this model system, DA depended significantly on body length and geographic origin, although mean signed asymmetry (mean DA) was not significant in the sample as a wh…
Global Perspective on Marital Satisfaction
2020
Across the world, millions of couples get married each year. One of the strongest predictors of whether partners will remain in their relationship is their reported satisfaction. Marital satisfaction is commonly found to be a key predictor of both individual and relational well-being. Despite its importance in predicting relationship longevity, there are relatively few empirical research studies examining predictors of marital satisfaction outside of a Western context. To address this gap in the literature and complete the existing knowledge about global predictors of marital satisfaction, we used an open-access database of self-reported assessments of self-reported marital satisfaction wit…
Psychometric properties of the CYBVICS cyber-victimization scale and its relationship with psychosocial variables.
2019
The main goal of the present study was to analyze the psychometric properties of the revised version of the Adolescent Cyber-Victimization Scale (CYBVICS). This scale is composed of 18 items that assess direct and indirect cyber-victimization. Two subsamples participated in the present study. Sample 1 included 1318 adolescents (47.4% boys) from 12 to 16 years old (M = 13.89, SD = 1.32). Sample 2 was composed of 1188 adolescents (51.5% girls) from 12 to 16 years old (M = 14.19, SD = 1.80). First, an exploratory factor analysis was conducted on sample 1. Results yielded a bifactor structure: direct cyber-victimization and indirect cyber-victimization. To confirm the structure of the CYBVICS, …
Finnish students’ enjoyment and anxiety levels during fitness testing classes
2020
Background: Fitness testing is a commonly applied learning and teaching practice implemented in both secondary and elementary school physical education (PE). Many teachers believe that by using a variety of different tests, they are able to provide students with feedback regarding their fitness status, and furthermore, increase students’ willingness to be physically active later in their lives. However, empirical evidence concerning students’ affective responses during fitness testing classes is limited. Purpose: The primary aim of the study was to investigate whether students’ perceptions of enjoyment and anxiety differed between two different types of fitness testing classes and PE in gen…
The Low Dimensionality of Development
2020
AbstractThe World Bank routinely publishes over 1500 “World Development Indicators” to track the socioeconomic development at the country level. A range of indices has been proposed to interpret this information. For instance, the “Human Development Index” was designed to specifically capture development in terms of life expectancy, education, and standard of living. However, the general question which independent dimensions are essential to capture all aspects of development still remains open. Using a nonlinear dimensionality reduction approach we aim to extract the core dimensions of development in a highly efficient way. We find that more than 90% of variance in the WDIs can be represen…
An appraisal of the fit of a cognitive behavioural model of headache in University students
2018
The aim of this study was to evaluate the fit of a cognitive behavioural model of headache in the population of University students, from Córdoba,Argentina. The direct and indirect contributions to pain intensity of control beliefs, beliefs and thoughts about pain and coping strategies weredetermined, as were the direct contributions of pain behaviours and disability. The sample was comprised of 382 students of both genders fromseveral Universities. Multiple instruments were administered to measure the variables proposed in the cognitive behavioural model of headachefollowed by a descriptive and exploratory analysis of the data. Structural equation modelling was used and revealed an accepta…
Loneliness and its relation to mental health in the general population: Validation and norm values of a brief measure
2021
Abstract Background Loneliness has been increasingly recognized as an important determinant of mental health. The purposes of this study were to (1) determine the degree of loneliness of women and men across different age groups, (2) explore its association with distress, (3) psychometrically evaluate the Three-Item Loneliness Scale, (4) provide norm values. Methods The Three-Item Loneliness Scale was applied in a representative survey of the German population (N=2527; 14–95 years). Standardized scales were used measuring distress (depression and anxiety symptoms, perceived stress, hopelessness, suicidal ideation, fatigue, life satisfaction). Factor structure and measurement invariance acro…
