Gender moderates the association between psychopathic traits and aggressive behavior in adolescents

The Longitudinal Effect of Peer-Nominated Popularity on Defending Behaviors in Chinese Adolescents: The Moderating Role of Manipulative Traits, Desired Popularity, and Gender

The factors influencing popular adolescents to defend victims require further exploration, particularly concerning their traits and the desire for higher peer status. In this one-year longitudinal study, 2464 Chinese adolescents (48.50% girls, Mage = 13.40 years, SD = 0.61) were investigated to examine the relationship between peer-nominated popularity, manipulative traits, desired popularity, and defending behaviors. The results revealed that peer-nominated popularity had a positive predictive effect on Chinese adolescents' defending behaviors. Furthermore, this longitudinal association was accentuated by desired popularity and manipulative traits in girls but was not in boys. Specifically, popular girls with high desired popularity demonstrated a higher likelihood of engaging in defending behaviors compared to other girls. These findings carry significant implications for understanding the influencing factors behind peer status and adolescents' defending behaviors.

Basic psychological need satisfaction and aggressive behavior: the role of negative affect and its gender difference

Background

Basic psychological need satisfaction (BPNS) is a significant factor in a person's development, especially for adolescents, and the failure to satisfy these basic needs may contribute to individuals' aggressive behavior. However, it is still unclear about the underlying mechanism by which BPNS is negatively associated with aggressive behavior. This study aimed to explore the relationship between BPNS and aggressive behavior in Chinese adolescents, with a focus on the mediating role of negative affect and its gender differences.

Method

A sample of 1,064 junior high school students from three schools in China were selected randomly for the cross-sectional survey. The revised Need Satisfaction Scale, the Positive and Negative Affect Schedule, and Youth's Self-Report were used to measure BPNS, affect, and aggressive behavior. The proposed model was examined by the structural equation modeling test and multi-group comparison analysis.

Results

The results showed that BPNS was negatively linked with adolescents' aggressive behavior, and this effect was mediated by negative affect. Moreover, multigroup analysis demonstrated that there existed a stronger negative association between BPNS and negative affect in female group. Also, the mediating effect of negative affect in the model was greater for girls.

Conclusions

Our findings highlighted the importance of BPNS in adolescents' social behavior (i.e., aggressive behavior), and reveal disparate patterns in how BPNS affects aggressive behavior in girls as compared to boys.

Callous and Unemotional Traits as Precursors to the Development of Female Psychopathy

OBJECTIVE

Conduct a systematic review concerning the literature that reflects whether the callous and unemotional traits present in childhood and/or adolescence are precursors in the development of female psychopathy in adulthood.

MATERIALS AND METHODS

A systematic review involved consulting three databases-EBSCO, the Web of Science, and PubMed-for peer-reviewed and quantitative studies within the period 2000-2023. Nine articles with quality of three and above were included.

RESULTS

The presence of callous and unemotional traits designates a group of youth that show characteristics associated with psychopathy, specifically when predicting a more severe and chronic pattern of antisocial behaviour. Children with high rates of callous and unemotional traits, who show symptoms of attention deficit hyperactivity disorder in combination with severe conduct problems, are most likely to show features associated with psychopathy. The multidimensional psychopathy construct is considered a better predictor of future and stable antisocial behaviour than the callous and unemotional traits alone model.

CONCLUSIONS

According to the studies selected, the callous and unemotional traits in childhood seem to be precursors of female psychopathy in adulthood, but only because of the way they seem to enhance conduct problems, disruptive behaviour disorders, and, as a possible outcome, delinquency and antisocial traits, which may be precursors of future psychopathy.

Autistic Traits and Cyberbullying Involvement Mediated by Psychopathologies and School Functions in a Nationally Representative Child Sample

Cyberbullying has become an international concern among youth with autistic traits in the digital age. It draws the attention of professionals in mental health and education due to its potentially severe psychosocial and academic impacts. However, there is limited knowledge about the mediators for these associations. This study investigated whether school dysfunction and comorbid psychopathologies mediated the link between autistic traits and cyberbullying. We used a nationally representative sample of 9,483 students (9-14 years of age). The instruments included the Social Responsiveness Scale for autistic traits; the Cyberbullying Experiences Questionnaire for cyberbullying victimization and perpetration; the Swanson, Nolan, and Pelham, version IV for inattention, hyperactivity/impulsivity, and oppositional behaviors; the Child Behavior Checklist for anxiety/depression; and the Social Adjustment Inventory for Children and Adolescents for impaired school functions. Multiple mediation models were used for statistical analyses. The results showed that the 1-year prevalence rates of pure victims, pure perpetrators, and bully-victims of cyberbullying were 7.9 percent, 2.4 percent, and 5.7 percent, respectively. Cyberbullying victimization and perpetration were positively associated with autistic traits, school dysfunction, and comorbid psychopathologies. The associations between autistic traits and cyberbullying victims and bully-victims were significantly mediated by school dysfunction and hyperactivity/impulsivity (only for bully-victims), independent of sex and age. Our results suggest that early identification and intervention of these difficulties may mitigate the risks of cyberbullying. ClinicalTrials.gov ID: NCT02707848.

Genetic versus environmental influences on callous-unemotional traits in preadolescence: The role of parenting and parental psychopathology

Children with callous-unemotional (CU) traits are at risk for severe conduct problems. While CU traits are moderately heritable, parenting also predicts risk. However, few studies have investigated whether parenting factors (e.g., acceptance, conflict, parental psychopathology) moderate the etiology of CU traits, while accounting for gene-environment correlations. To address this knowledge gap, we used data from 772 twin pairs from the Adolescent Brain and Cognitive Development Study to test bivariate models that explored overlapping etiological influences on CU traits and child reports of their parenting environment. We also used gene-by-environment interaction models to test whether parenting moderated genetic versus environmental influences. There were no overlapping etiological influences on CU traits and parental acceptance, but modest genetic and non-shared environmental overlap between CU traits and family conflict. Parental acceptance and psychopathology moderated non-shared environmental influences, with stronger non-shared environmental influences on CU traits among children who experienced lower parental acceptance and greater parental psychopathology. Family conflict only moderated environmental influences when models did not covary for conduct problems. Parental acceptance and parental psychopathology may be specific environmental protective and risk factors for CU traits, whereas family conflict may represent a general environmental risk factor for both CU traits and conduct problems.

Dark triad and cyber aggression among Chinese adolescents during COVID-19: A moderated mediation model

During the COVID-19 pandemic, the use of online learning has become a necessary choice for students, and would increase the probability of cyber aggression (CA). Despite the relationship between Dark Triad and CA previous was explored in previous research, the underlying psychological mechanism of CA in adolescents is still unclear. The current study aimed to examine the mediating role of moral disengagement (MD) and the moderating of gender in the relationship between Dark Triad and CA. A sample consists of 501 Chinese adolescents (246 females; 255 males) between the ages of 11 ~ 20. Participants completed the Dirty Dozen Scale, Moral Disengagement Scale, and Cyber Aggressive Behavior Scale. Results show that higher levels of dark personality were associated with higher levels of MD and CA. Moral disengagement partially mediated this positive effects of dark personality on CA. Moreover, gender moderated the mediation model. Specially, the positive relationship between dark triad personality and CA was stronger among females adolescents. These findings advance the understanding of how dark triad personality induces Chinese adolescents' cyber aggressive behavior.

Resisting aggression in social contexts: The influence of life-course persistent antisocial behavior on behavioral and neural responses to social feedback

•

Negative social feedback (vs positive / neutral) evoked more retaliatory aggression.

•

Persistent and desistent antisocial development associated with similar and dissociable neural activity:

•

During social feedback processing: Increased Insula (both groups) or dlPFC activation (desisters)

•

During retaliation: Increased dlPFC and ACC activity after positive feedback.

•

During retaliation: ACC activity correlated with inhibition of retaliation (desisters)

Early adulthood has long been recognized as a potential turning point for the development of antisocial behavior, due to changes in social contexts and ongoing psychological and neurobiological maturation. However, it remains unclear how different developmental trajectories of antisocial behavior, their neural underpinnings, and individual differences in psychopathic traits may help explain the distinct developmental outcomes of individuals who persist in or desist from antisocial behavior in early adulthood - such as how they respond to others in social contexts. Therefore, in the current study, young adults (aged 18–30, 68% male) with a persistent or desistant antisocial trajectory (N = 54), as well as healthy controls (N = 39), completed the Social Network Aggression Task, during which they received positive, neutral, or negative feedback on a personal profile and got the opportunity to retaliate by blasting a loud noise. On a behavioral level, results indicated that in all groups, negative peer feedback evoked higher retaliatory aggression, compared to positive and neutral feedback. On a neural level, when receiving social feedback, individuals with persistent or desistent trajectories showed both similar and dissociable patterns of neural activity; desisting and persisting trajectory groups showed higher activity in the Insula, and the desisting trajectory group showed higher activity in dlPFC. Finally, when participants retaliated, they showed increased dlPFC and ACC activity following positive relative to neutral and negative feedback, where ACC activity correlated most strongly with inhibition of retaliatory responses in the desisting trajectory group. Together, these findings provide novel insights in dissociable patterns of brain activity that may increase our understanding of the mechanisms underlying different developmental trajectories of antisocial behavior.

Gender Differences in the Personality Correlates of Reactive and Proactive Aggression in a Spanish Sample of Young Adults

Since the conceptual distinction of reactive and proactive aggression has been proposed, numerous studies have tried to disentangle the correlates of each function of aggression. While reactive aggression tends to be more strongly related to impulsivity, angry reactivity, or hostility, proactive aggression has proved to be more associated with psychopathic traits and goal-directed behaviors. However, in addition to the current debate about the actual distinction of reactive and proactive aggression, the study of gender differences is still scarce. Thus, the aim of the current study is to evaluate the distinctiveness of reactive and proactive aggression by means of the examination of their differential personality correlates (i.e., HEXACO, psychopathic traits, and impulsivity facets), as well as the assessment of gender differences in those relationships. To that end, a sample composed of 326 young adults aged 18-34 was recruited in Spain. The results evidenced unique associations of reactive and proactive aggression with a set of personality traits, including the HEXACO factors, psychopathic traits, and impulsivity facets, both at raw and residual level. Furthermore, when all the variables were entered in the model, proactive aggression remained strongly related to the factor of Honesty/humility and Emotionality, whereas reactive aggression remained associated with the impulsive/irresponsive factor of psychopathy and, specifically, with the facet of negative urgency, as well as with lack of Agreeableness. Likewise, some gender differences emerged as regards certain correlates. Specifically, proactive aggression was related with lack of Agreeableness and sensation seeking only in males and with the impulsive/irresponsive factor of psychopathy only in females, although these differences were not statistically significant. The conceptual and practical implications of these finding are discussed in terms of prevention.

Interaction of Psychopathic Traits Dimensions in the Prediction of Psychological and Physical Child-to-Parent Violence in Adolescents

This study examined the longitudinal relationships between three psychopathic trait dimensions (callous-unemotional, CU; grandiose-manipulative, GM; and impulsive-irresponsible, II) and their interaction in the prediction of psychological and physical child-to-parent violence (CPV). Furthermore, the study examined whether the predictive relationships were different for boys and girls. A total of 765 adolescents (463 girls), with a mean age of 15.28 years (SD = 1.04), completed measures of the psychopathic trait dimensions (CU, GM, and II) and psychological and physical CPV at the beginning of the study and six months later. At the cross-sectional level, all the psychopathic trait dimensions were related to psychological and physical CPV, although the effect sizes were small. At the longitudinal level, II predicted increased psychological CPV. A significant three-way interaction between the three psychopathic trait dimensions (CU, GM, and II) indicated that the longitudinal association between II and physical CPV was higher for adolescents with high CU and low GM. However, the predictive model did not differ for boys and girls.

An antisocial alchemy: Psychopathic traits as a moderator of the different forms and functions of aggression in delinquency and conduct disorder among youth

The aim of the present study is to examine the possible role of psychopathic traits as a moderator of the aggression-antisociality/delinquency link. Our sample was composed of 567 youth (M = 15.91 years, SD = 0.99 years, age range = 14-18 years) from Portugal. Results indicated that psychopathic features significantly moderate four different forms and functions of aggression - proactive overt, proactive relational, reactive overt, and reactive relational - when predicting delinquency. However, psychopathic traits only significantly moderate proactive relational aggression when predicting Conduct Disorder. Psychopathic traits and aggression constitute an antisocial alchemy for antisocial behavior but more research is needed about moderation effects therein particularly among clinical and justice system involved samples of youth to inform behavioral interventions.

Perpetration of and Victimization in Cyberbullying and Traditional Bullying in Adolescents with Attention-Deficit/Hyperactivity Disorder: Roles of Impulsivity, Frustration Intolerance, and Hostility

Victimization and perpetration of cyberbullying and traditional bullying are prevalent among adolescents with attention-deficit/hyperactivity disorder (ADHD). This study examined the associations of impulsivity, frustration discomfort, and hostility with victimization and with the perpetration of cyberbullying and traditional bullying in adolescents with ADHD. Self-reported involvement in cyberbullying and traditional bullying was assessed in 195 adolescents with a clinical diagnosis of ADHD. Adolescents also completed questionnaires for impulsivity, frustration discomfort, and hostility. Caregivers completed the Child Behavior Checklist for adolescents’ ADHD, internalization, oppositional defiance, and problems with conduct. The associations of impulsivity, frustration discomfort, and hostility with victimization and perpetration of cyberbullying and traditional bullying were examined using logistic regression analysis. The results demonstrated that after the effects of demographic characteristics and behavioral problems were controlled for, frustration intolerance increased the risks of being cyberbullying victims and perpetrators whereas hostility increased the risks of being the victims and perpetrators of traditional bullying. Impulsivity was not significantly associated with any type of bullying involvement. Prevention and intervention programs should alleviate frustration intolerance and hostility among adolescents with ADHD.

Parental Corporal Punishment and Peer Victimization in Middle Childhood: A Sex-Moderated Mediation Model of Aggression

There is a peak in peer victimization during middle childhood, with multiple negative consequences. Parental use of corporal punishment and child aggression are the most widely studied predictors of this phenomenon. The aim of the present study was to analyze whether parental use of corporal punishment affects peer victimization through child aggression. This mediation model was explored for both mothers and fathers and for both physical and relational forms of aggression and peer victimization. Furthermore, we also analyzed whether the mediation models were moderated by the sex of the child. Participants were 234 third graders (46% girls). Child aggression and victimization were measured by peers using the Mini Direct Indirect Aggression Inventory. Independent measures of mother's and father's use of corporal punishment were obtained from a PCA of items from the Parental Styles and Dimensions Questionnaire (PSDQ). Conditional process modeling was carried out using a macro for SPSS developed by Hayes (2013). Results indicated that aggression mediated the relation of parental corporal punishment to peer victimization. Some interesting moderating effects of sex in this mediation model were found; specifically, physical, and relational aggression mediated the relation of maternal corporal punishment to peer victimization only in boys. Few studies to date have addressed the connection between aggressive behavior and peer victimization as outcomes of corporal punishment, taking into consideration the role of parent's and child's sex, and both physical and relational forms of aggression and victimization during childhood.

Bivariate Growth of Perceived Containment and Functions of Aggression Over 2 Years

Perceived containment is the belief that one can be controlled by the limits set by authority figures, with low levels of perceived containment indicating that one does not believe they can be controlled by others. Low levels of perceived containment have been associated with a range of problem behaviors in youth, including proactive and reactive aggression. However, the stability of perceived containment across time and authority figures in middle childhood is not well understood. Additionally, more research is needed to understand how perceived containment is associated with the trajectories of related problem behavior, such as proactive and reactive functions of aggression. Thus, the current study evaluated univariate and bivariate growth trajectories of perceived containment and proactive and reactive aggression across 2 years in middle childhood. Participants were 249 elementary school youth (41% female, 7-10 years old). Children self-reported on perceived containment and proactive and reactive aggression at 4 time points across a two-year period. Results indicated that perceived containment and proactive aggression remained stable, while reactive aggression increased over a two-year period. Bivariate models indicated that perceived containment was negatively associated with the latent intercept of proactive and reactive aggression; however, perceived containment was not significantly associated with growth of reactive aggression. Findings and implications for treatment and prevention are discussed in turn.

ADHD symptoms and callous-unemotional traits as predictors of violent media use in adolescence

We investigated ADHD symptoms and CU traits as predictors of violent media use in adolescence, controlling for delinquency and ODD symptoms. The effects on of disinhibition and arousal to negative stimuli, core characteristics of ADHD symptoms and CU traits, and of gender were investigated. At age 15, 88 adolescents, 50 % boys reported on CU traits, ADHD symptoms and delinquency. Parents rated the adolescents' CU traits, ADHD- and ODD symptoms. At age 16, adolescents reported on their media habits and performed tests of disinhibition and arousal to negative stimuli. Boys had higher levels of CU traits and violent media use and girls had higher levels of arousal to negative pictures. CU traits and inattention symptoms predicted violent media use, the latter association applying only to boys, with CU traits being the strongest predictor. Low arousal to threat pictures explained variance in violent media use, above CU traits. Attraction to violent media seems affected by problem behaviors, with CU traits coming forth as especially important.

Mindfulness, impulsivity, and moral disengagement as parameters of bullying and victimization at school

The aim of the present study was to examine the existing association between mindfulness, impulsivity, moral disengagement, and bullying experiences at school. Longitudinal data were collected in three points in time (T1, T2, T3) with 6 months interval between them. Participants were 558 adolescents attending secondary schools in Cyprus, with their ages ranging from 14 to 17 years (M = 15.3; standard deviation = 0.69). Through structural equation modeling, it was found that mindfulness at T1 had a significant negative effect on both impulsivity and moral disengagement at T2 and these, in turn, had a positive effect on bullying and victimization at T3. Thus, mindfulness had an indirect effect on both bullying and victimization, fully mediated by impulsivity and moral disengagement.

Are Sexist Attitudes and Gender Stereotypes Linked? A Critical Feminist Approach With a Spanish Sample

This study aims to verify the psychometric properties of the Spanish versions of the Social Roles Questionnaire (SRQ; Baber and Tucker, 2006), Modern Sexism Scale (MS), and Old-Fashioned Sexism Scale (OFS; Swim et al., 1995; Swim and Cohen, 1997). Enough support was found to maintain the original factor structure of all instruments in their Spanish version. Differences between men and women in the scores are commented on, mainly because certain sexist attitudes have been overcome with greater success in the current Spanish society, while other issues, such as distribution of power in organizational hierarchies or distribution of tasks in the household, where traditional unequal positions are still maintained. In all cases, it was found that men showed greater support for sexist attitudes. The correlations between the three instruments were as expected in assessing sexist attitudes that tend to relate to each other. Eventually, we found no empirical evidence for the postulated link between sexist attitudes and traditional gender stereotypes. Our results call for the validity and effectiveness of the classic theories of gender psychology, such as gender schema theories (Bem, 1981; Markus et al., 1982) and the notion of a gender belief system (Deaux and Kite, 1987; Kite, 2001).

Arab youth involvement in violence: A socio-ecological gendered perspective

BACKGROUND

Previous research has extensively used a socio-ecological perspective to find the correlates of youth involvement in violence. However, little is known about the extent to which ecological factors correlated with youth violence are affected by gender, especially in non-Western cultures.

OBJECTIVE

The role of gender in the association between individual, family, and contextual factors and Arab youth involvement in several types of violence (severe physical, moderate physical, and verbal and indirect violence) was explored using a socio-ecological perspective.

PARTICIPANTS AND SETTING

The study was based on a large random sample of 3,178 Arab students, aged 11-18, from Israel.

METHODS

Information was collected from the adolescents through a structured, anonymous self-report questionnaire which they completed in the classroom under the guidance of a research assistant. Confidentiality and anonymity were ensured for all participants.

RESULTS

Gender was found to moderate the association between impulsivity and parental support and all types of violence except verbal violence. No interaction effect was found in the association between affiliation with delinquent peers and exposure to community violence and Arab youth involvement in violence.

CONCLUSIONS

The results emphasize the importance of exploring gender differences with respect to risk and protective factors for violence. This knowledge is an important step in the design and implementation of gender-specific intervention strategies to deal with youth violence.

Psychopathic Traits and Moral Disengagement Interact to Predict Bullying and Cyberbullying Among Adolescents

The aim of this study was to test a model in which psychopathic traits (callous-unemotional, grandiose-manipulative, and impulsive-irresponsible) and moral disengagement individually and interactively predict two types of bullying (traditional and cyberbullying) in a community sample of adolescents. A total of 765 adolescents (464 girls and 301 boys) completed measures of moral disengagement and psychopathic traits at Time 1, and measures of bullying and cyberbullying at Time 1 and 1 year later, at Time 2. The results showed that callous-unemotional traits predicted both traditional bullying and cyberbullying, grandiose-manipulative and impulsive-irresponsible traits only predicted traditional bullying, and moral disengagement only predicted cyberbullying. Callous-Unemotional Traits × Moral Disengagement and Grandiose-Manipulative × Moral Disengagement were significantly correlated with the residual change in cyberbullying. Callous-unemotional traits were positively related to cyberbullying at high levels of moral disengagement but not when moral disengagement was low. In contrast, grandiose-manipulative traits were positively related to cyberbullying at low levels of moral disengagement but not when moral disengagement was high. These findings have implications for both prevention and intervention. Integrative approaches that promote moral growth are needed, including a deeper understanding of why bullying is morally wrong and ways to stimulate personality traits that counteract psychopathic traits.

Longitudinal relations between beliefs supporting aggression and externalizing outcomes: Indirect effects of anger dysregulation and callous-unemotional traits

Aggression is prevalent in early- to mid-adolescence and is associated with physical health and psychosocial adjustment difficulties. This underscores the need to identify risk processes that lead to externalizing outcomes. This study examined the extent to which the effects of three dimensions of beliefs supporting aggression on physical aggression and externalizing behavior are mediated by anger dysregulation and callous-unemotional (CU) traits. Three waves of data were collected from a primarily African American (77%) sample of 265 middle school students between the ages of 11 and 15 (52% were female). We found evidence supporting mediation such that the effects of beliefs supporting instrumental aggression and beliefs that fighting is sometimes necessary at Wave 1 on student-reported physical aggression at Wave 3 were mediated by CU traits at Wave 2, and relations between beliefs supporting reactive aggression at Wave 1 and teacher-report of student frequencies of physical aggression and externalizing behavior at Wave 3 were mediated by anger dysregulation at Wave 2. Our findings demonstrated the importance of distinguishing between dimensions of beliefs supporting aggression, as differential paths emerged between specific beliefs, CU traits and anger dysregulation, and externalizing outcomes. These findings have important clinical implications, as they suggest that specific dimensions of beliefs supporting aggression could be targeted based on whether an individual is at risk for behavior patterns characterizing CU traits or anger dysregulation.

Psychopathic Traits' Differential Relations With Aggression Forms: Considering the Roles of Gender and Gender Role Adherence

Research has yielded inconsistent findings between psychopathy and aggression, with findings varying as a function of type of psychopathic trait (i.e., affective, behavioral) and aggression form (i.e., physical, relational). Although some research has explored the role of gender in these relations, gender role adherence has received scant attention. Using an undergraduate sample (N = 320), we aimed to clarify mixed findings on how psychopathic traits relate to aggression forms across males and females; examine how psychopathic traits relate to gender role adherence; and ascertain the roles of gender and gender role adherence in the relations between psychopathic traits and aggression. Psychopathic traits manifested differential relations with gender role adherence such that Psychopathic Personality Inventory-Revised (PPI-R) Fearless Dominance was most strongly and positively associated with Bem Sex-Role Inventory (BSRI) Masculinity, whereas PPI-R Self-Centered Impulsivity and Coldheartedness were negatively associated with BSRI Femininity. BSRI Masculinity and Femininity were uniquely and differentially associated with aggression forms, and remained associated with aggression forms above and beyond both psychopathy and gender. In addition, BSRI Masculinity moderated the relations between PPI-R Self-Centered Impusivity and physical aggression such that those high in both Masculinity and Self-Centered Impulsivity were most prone to physical aggression. In contrast, although BSRI Femininity was negatively associated with aggression, it did not buffer against aggression in the presence of psychopathic traits. Overall, our results underscore the importance of considering gender role adherence in understanding differences in psychopathy and aggression.

Effect of a Mindfulness Training Program on the Impulsivity and Aggression Levels of Adolescents with Behavioral Problems in the Classroom

Objective: The aim of the present study was to analyze the effects of a mindfulness training psycho-educative program on impulsivity and aggression levels in a sample of high school students.

Methods: A randomized controlled trial with pre-test–post-test measurements was applied to an experimental group and a control group (waiting list). The Barratt Impulsivity Scale (BIS-11) Patton et al. (1995) and the Aggression Questionnaire (Buss and Perry, 1992) were used.

Results: Statistical analyses showed a significant decrease in the levels of impulsivity and aggressiveness in the experimental group compared with the control group. These results have important implications for improving the level of academic engagement and self-efficacy of students and for reducing school failure.

Conclusion: This is one of the first studies showing the effectiveness of mindfulness training at reducing impulsive and aggressive behaviors in the classroom. The efficacy of mindfulness-based programs is emphasized.
