Genetic association study of childhood aggression across raters, instruments, and age
2021
AbstractChildhood aggressive behavior (AGG) has a substantial heritability of around 50%. Here we present a genome-wide association meta-analysis (GWAMA) of childhood AGG, in which all phenotype measures across childhood ages from multiple assessors were included. We analyzed phenotype assessments for a total of 328 935 observations from 87 485 children aged between 1.5 and 18 years, while accounting for sample overlap. We also meta-analyzed within subsets of the data, i.e., within rater, instrument and age. SNP-heritability for the overall meta-analysis (AGGoverall) was 3.31% (SE = 0.0038). We found no genome-wide significant SNPs for AGGoverall. The gene-based analysis returned three sign…
Agresividad y afrontamiento en la adolescencia. Una perspectiva intercultural
2008
La conducta agresiva es objeto de estudio con la finalidad de comprender los mecanismos básicos que causan y regulan esta conducta. La interculturalidad es una realidad que caracteriza a nuestra escuela y nuestra sociedad y el incremento acentuado en los últimos años de población inmigrante y el aumento de adopciones internacionales han generado en algunos centros un alto porcentaje de alumnos procedentes de otras culturas, lo que ha motivado en algunos centros un incremento de conductas agresivas y antisociales. El objetivo del estudio es analizar la conducta agresiva, los procesos implicados y los mecanismos de afrontamiento en una muestra de 1557 adolescentes entre 12 y 15 años, de Prime…
Los problemas de violencia en los adolescentes. ¿Incapacidad educativa de los progenitores?
2013
Es una realidad innegable que cada vez aparece más información en los medios de comunicación y en la producción científica que nos advierte de un incremento de la violencia y de falta de valores entre los jóvenes, sin lograr comprender qué sucede con ellos o, si bien, estamos ante una generación de madres y padres incompetentes para educar en una sociedad tildada de deshumanizada, tecnológica y global. Por ello, el objetivo de este artículo es partir de interrogantes y buscar explicaciones en estudios del espectro científico acerca del grado o tipo de influencia que ejercen los progenitores, desde sus estilos educativos, en el desarrollo prosocial versus antisocial de su progenie, contempla…
Reduction of sexist attitudes, romantic myths, and aggressive behaviors in adolescents: Efficacy of the DARSI program
2019
ABSTRACT. Background: The DARSI program (Developing Healthy and Egalitarian Adolescent Relationships) aims to prevent peer aggressive behaviors inside and outside social networks and educate adolescents on gender equality. The objective of this study was to evaluate the effects of the program on the reduction of sexist attitudes, myths of romantic love and aggressive behaviors in adolescents. Method: 191 adolescents, aged 12 to 17 years (53.93% girls), assigned to an experimental group (3 classrooms) and two control groups (6 classrooms in two educational centers) participated in this study. A quasi-experimental design with control group was used and the effectiveness of the program was eva…
The Structure and Correlates of a Measure of Prosocial Moral Reasoning in Adolescents from Spain
2013
Examined the structure and correlates of a measure of prosocial moral reasoning in a sample of young and middle-aged adolescents. 1556 students (53% male, M age = 13.12, SD = .87) from Valencia, Spain completed paper-and-pencil measures of prosocial moral reasoning (PROM), empathy, prosocial behaviors, and aggression. As expected, a series of confirmatory factor and structural equation modeling analyses revealed a four-factor solution of the PROM to have the best fit (as compared to alternative models) among Spanish youth (across gender and grade). Moreover, higher level and other-oriented forms of prosocial moral reasoning were generally positively related to empathy and prosocial behavior…
El trastorn de dèficit d'atenció amb hiperactivitat (TDAH) en població infantil i juvenil
2012
Fruit de la dedicació professional de les autores i enfront d'un problema no sols no resolt, sinó que es considera que està insuficientment abordat, el trastorn de dèficit d'atenció amb hiperactivitat (TDAH) en població infantil i juvenil, es planteja primerament una revisió de la bibliografia, seguida d'un recull de dades sobre la situació actual (amb abundància d'informació procedent dels Estats Units) i d'algunes consideracions i propostes per a posar en marxa les intervencions al nostre àmbit de referència, com ara l'educació que han de rebre, les concepcions morals, els hàbits, etc. Perquè avui dia els infants estan exposats a nombroses influències que han desencadenat que es disparen …
Comunicar : revista científica iberoamericana de comunicación y educación
2021
En el marco de la escuela inclusiva, el aprendizaje socioemocional y personalizado fomenta la implicación del alumnado en la vida del aula y se relaciona con la disminución de la conducta desadaptativa. El objetivo de este estudio es analizar el impacto de un programa de educación socioemocional en la agresividad y la inestabilidad emocional en la infancia. Han participado 555 niños/as de 7 a 12 años (M=9,2 y DT=1,5), 55,5% niños y 45,5% niñas. Estudian Educación Primaria en seis colegios públicos del área metropolitana de Valencia (España). La muestra se ha distribuido en un grupo experimental (317 niños/as; 57,2% de la población total participante) y un grupo control (238 niños/as; 42,8% …
Behavioural and neurochemical effects after repeated administration of N-ethylpentylone (ephylone) in mice
2022
N-ethyl-pentylone (NEP), also known as "ephylone" and N-ethylnorpentylone, has been identified as one of the most recent novel psychostimulants to emerge into the illicit drug market and it has been associated with some intoxications and even fatalities. However, little is known about the consequences of its repeated consumption as well as the role of the monoaminergic system in such consequences. Thus, the aim of our study was to investigate the neurochemical profile and the behavioural effects after both acute and repeated NEP exposure. Male OF1 mice were acutely (1, 3, 10 mg/kg, i.p.) or repeatedly (1, 3, 10 mg/kg, i.p., 5 days, twice/day) exposed to NEP, and anxiety-like behaviour, aggr…
The Mediating Role of Classroom Climate on School Violence
2021
Mediation analysis has been confirmed as a very useful statistical tool in the social sciences, especially in school-related studies. This type of analysis was used in the present study to examine the mediating role of classroom climate (measured with the classroom environmental scale), categorized into three dimensions, namely involvement, affiliation, and teacher support, on the relationship between peer victimization and peer aggression. The participants consisted of 2011 adolescents (50.67% boys and 49.32% girls), aged between 12 and 18 years old (M = 14.17
A visceral method to study gender-based violence among youth
2022
People do not always verbalise what they really think, and this becomes significant when analysing individuals’ publicly expressed views on gender equality and gender-based violence. We developed a new method we call visceral to find out about subjective beliefs that go unrecognised and we do not admit to ourselves. Here, we explain the characteristics of that method, its stages, and the decisions involved in implementing it. We show how it applied to young people in a specific project about sexual violence. Through the systematic use of previously selected photographs, the method enables us to discover the deeper invisible patterns that influence people’s behaviour and are an obstacle to a…
