Spanish Validation of the Emotion Regulation Questionnaire for Children and Adolescents (ERQ-CA): Introducing the ERQ-SpA

Research on emotion regulation is now extensive and shows the benefits of the adaptive management of emotions for social functioning and psychological well-being. Our purpose was to test the psychometric properties of the Emotion Regulation Questionnaire for Children and Adolescents with a sample of nonclinical Spanish adolescents. A total of 462 secondary education students (223 girls, mean age = 13.89 years, SD = 1.38) participated. The instrument proved to be two-factor and gender-invariant. Results revealed the temporal stability of both emotion regulation strategies, while the predictive validity study revealed that depressive symptoms were negatively related to cognitive reappraisal, and positively related to expressive suppression. Our findings support the use of the ERQ-SpA in Spanish adolescents

Longitudinal study of physical activity in college students: Testing self-determination theory based on stages of change

The main purpose of this study was to longitudinally test the relationships of Self Determination Theory variables on physical activity, analyzing the model based on stages of change. The study is a longitudinal and quantitative research. We have developed a longitudinal cross-lagged design for structural equation models of three time points and multi-group analysis. Participants were 772 Spanish college students from the University of Zaragoza (M = 19.74, SD = 2.76) studying several degrees. Participants completed different self-reports, assessing: physical activity, stages of change, motivation and basic psychological needs, at three time points (November, January and March). The analysis indicated that intrinsic motivation positively predicted physical activity at the 3-time points, both directly and indirectly. Intrinsic motivation was negatively predicted by autonomy and positively predicted by competence (from time point 2 to 3). No relationships were found with relatedness for the entire sample. Regarding the stages of change multi-group analysis were run: in the low active group, we found a negative relationship between relatedness and physical activity, and a positive association between competence and intrinsic motivation and physical activity, whereas intrinsic motivation did not predict physical activity. Our findings showed that intrinsic motivation was the most consistent predictor of physical activity. The competence need played an essential role in intrinsic motivation and physical activity for both active and passive subjects. However, the basic psychological needs have not worked as indicated by the theory when it was examined longitudinally. The findings of the study highlight the need for different strategies to improve physical activity levels according to the stages of change

The WaveDriving Course

In the last ten years our knowledge about the formation of traffic jams has changed substantially, so that the idea of »phantom traffic jam» could soon seem naive to us. But transforming traffic flows and eliminating traffic jams requires that each individual driver (human or non-human) understands their role in traffic flows, the genesis of traffic jams, and how to behave to avoid them. Based on previous studies we have termed this adaptive, anti-jam behavior Wavedriving. This paper presents the design and structure of an online WaveDriving course (WDC) conceived to teach to avoid traffic jams, as well as its first pilot tests. Although some improvements have been identified after the pilots, the preliminary results confirm that the WDC manages to transform car-following behavior of participants, from ordinary drivers to WaveDrivers

The NEXT experiment: A high pressure xenon gas TPC for neutrinoless double beta decay searches

Abstract Neutrinoless double beta decay (ββ0ν) is a hypothetical, very slow nuclear transition in which two neutrons undergo beta decay simultaneously and without the emission of neutrinos. The importance of this process goes beyond its intrinsic interest: an unambiguous observation would establish a Majorana nature for the neutrino and prove the violation of lepton number. NEXT is a new experiment to search for neutrinoless double beta decay using a radiopure high-pressure xenon gas TPC, filled with 100 kg of Xe enriched in Xe-136. NEXT will be the first large high-pressure gas TPC to use electroluminescence readout with SOFT (Separated, Optimized FuncTions) technology. The design consists in asymmetric TPC, with photomultipliers behind a transparent cathode and position-sensitive light pixels behind the anode. The experiment is approved to start data taking at the Laboratorio Subterráneo de Canfranc (LSC), Spain, in 2014

Transactional Links between Teacher-Adolescent Support, Relatedness, and Aggression at School: A Three-Wave Longitudinal Study

This study examines the reciprocal effects between two school-based relationships within the classroom-namely, perceived teacher support and relatedness with classmates-and school aggression (overt and relational) across two courses of secondary education. Participants were 654 adolescents (48% boys), who were assessed in three waves: first, at the beginning of the academic year (T0), second, at the end of the same academic year (T1), and third, at the beginning of the next academic year (T2) (Mage wave 1 = 13.98 years). Autoregressive cross-lagged modeling was applied. Results show a protective effect of relatedness against relational aggression in both genders. Moreover, we observed a protective effect of perceived teacher support at the beginning of the course for later school aggression as well as a risk effect if this perceived teacher support is maintained throughout the course. These effects were observed in relation with gender-atypical forms of aggression (overt in girls and relational in boys). Finally, aggression had negative consequences for relatedness in girls and for teacher support through the mediation of relatedness in boys. Gender differences and practical implications of these findings are discussed

Psychological Flexibility With Prejudices Increases Empathy and Decreases Distress Among Adolescents: A Spanish Validation of the Acceptance and Action Questionnaire–Stigma

Empathy is an emotional response that may facilitate prosocial behavior and inhibit aggression by increasing empathic concern for others. But the vicarious experience of other’s feelings may also turn into personal distress when the person has poor regulation skills and holds stigmatizing beliefs. In thinking about the processes that may trigger the experience of personal distress or empathic concern, research on the influence of psychological flexibility and inflexibility on stigma is showing promising results. Both processes are assessed with the Acceptance and Action Questionnaire–Stigma (AAQ-S). The current study sought to carry out a validity study of a Spanish version of the AAQ-S with a sample of adolescents aged 11–17 years. The study included an expanded test of its predictive validity with measures at three times to evaluate the role of psychological flexibility and inflexibility as risk or protective variables for the development of personal distress and/or empathic concern in the stigmatizer. Statistical analyses confirmed a two-correlated-factor solution, the adequate reliability of both factors, and their construct and predictive validity in the expected direction. The stigmatizer’s inflexible reaction to their stigmatizing thoughts predicted the occurrence of personal distress, whereas the stigmatizer’s flexible reaction to their stigmatizing thoughts predicted the occurrence of empathic concern for others. These findings confirm the importance of considering the role of regulatory skills in the experience of empathic concern or personal distress in the presence of stigmatizing thoughts, with possible implications for the promotion of prosocial behavior and the reduction of aggressive behavior among adolescents.

Effects of pubertal timing and pubertal tempo on social physique anxiety, self-determined motivation, and exercise in early adolescent girls

Purpose: Research has shown that there is a decrease in physical activity levels during early adolescence, especially for girls. Previous studies have shown that the social physique anxiety (SPA) may be a controlling factor influencing exercise motivation and engagement in this behavior; however, the potential role that puberty plays in this decrease has not been considered until now. The objective of the present study was to examine the impact of pubertal timing and pubertal tempo on SPA and exercise motivation and behavior. Methods: Data from 328 early adolescent girls, aged between 9 and 12 at the time of joining the study, were collected in 3 waves over a 2-year period. Using structural equation modeling techniques, different 3-time-point growth models were estimated to examine if earlier maturing and compressed maturing in girls had differential effects on SPA and exercise motivation and behavior. Results: The results from growth analyses suggest that early maturing (according to all the pubertal indicators considered, except menstruation) tends to translate into (1) an increase in SPA levels and (2) a decrease in exercise - in the latter case, by reducing self-determined motivation. However, no differential effects from any of the pubertal indicators were found for compressed maturing in girls. Discussion: These results highlight the need for increased efforts toward developing programs aimed at helping early maturing girls to cope with the challenges of puberty with a particular focus on SPA experiences and exercise motivation and behavior

Toroidal magnetized iron neutrino detector for a neutrino factory

A neutrino factory has unparalleled physics reach for the discovery and measurement of CP violation in the neutrino sector. A far detector for a neutrino factory must have good charge identification with excellent background rejection and a large mass. An elegant solution is to construct a magnetized iron neutrino detector (MIND) along the lines of MINOS, where iron plates provide a toroidal magnetic field and scintillator planes provide 3D space points. In this paper, the current status of a simulation of a toroidal MIND for a neutrino factory is discussed in light of the recent measurements of large θ13. The response and performance using the 10 GeV neutrino factory configuration are presented. It is shown that this setup has equivalent δCP reach to a MIND with a dipole field and is sensitive to the discovery of CP violation over 85% of the values of δCP
