Increases In Physical Aggression Research Articles

Relative likeability and relative popularity as sources of influence in children's friendships.

The present study contrasts two forms of peer status as sources of friend influence: Relative likeability and relative popularity. Participants included 310 children (142 boys, 168 girls), ages 9 to 12, in stable reciprocated friendships. Peer nominations were collected at two time points, 8 to 14 weeks apart. After removing overlapping variance through residualization, partners in each friend dyad were categorized into roles on the basis of relative (to the partner) popularity and relative (to the partner) likeability. Dyadic analyses compared more- and less-liked friends and more- and less-popular friends in terms of their influence over physical aggression, relational aggression, prosocial behavior, and academic achievement. Higher initial relational aggression, prosocial behavior, and academic achievement among more-liked partners predicted greater increases in the same among less-liked partners, but not the reverse. Unexpectedly, physical aggression among less-liked partners predicted increases in physical aggression among more-liked partners. More popular friends did not influence less popular friends on any of these variables, although (also unexpectedly) less-popular friends influenced the academic achievement of more-popular friends. Taken together, the findings suggest that during the pre- and early adolescent years, relative influence within a friendship tends to be apportioned on the basis of likeability, not popularity.

Trajectories of physical and relational aggression across early childhood: Relations with peer risk factors.

The goal of the current study was to examine trajectories of relational and physical aggression in early childhood and evaluate peer predictors of these trajectories (i.e., peer rejection, relational victimization, and physical victimization). The study spanned three-time points (T1 in the spring, T2 in the fall, and T3 in the spring) in early childhood (N = 300; 44.0% girls; Mage = 44.70 months, SD = 4.38; 3.0% African American/Black, 7.6% Asian/Asian American/Pacific Islander, 1.0% Hispanic/Latinx, 11.3% multiracial, 62.1% White, and 15.0% missing/unknown). Observations of peer victimization and teacher report of peer rejection were collected at T1, and teacher report of aggression was collected at all time points. Results from piecewise latent growth models demonstrated that both forms of aggression decreased from T1 to T2 as children entered a new classroom and increased from T2 to T3 as they remained in that classroom. The increase in physical aggression from T2 to T3 was only significant for boys. Peer rejection at T1 emerged as a predictor of both intercepts and slopes from T1 to T2, and physical victimization predicted the physical aggression intercept and physical aggression slope from T1 to T2. Children high on these peer risk variables had higher initial levels of aggression, followed by a greater decrease in aggression from T1 to T2. Results underscore the importance of studying incremental change in aggression in early childhood and suggest that children who experience negative peer treatment have greater fluctuations in aggression over time.

An Evidence-based Practice Project to Improve Sleep for Individuals with Autism

According to the Centers for Disease Control and Prevention Autism and Developmental Disabilities Monitoring (2023), autism spectrum disorder (ASD) is diagnosed in approximately 1 in 36 children. Common signs of ASD are difficulties with social interaction and communication, repetitive behaviors, delayed cognitive skills, and unusual sleep habits (Centers for Disease Control and Prevention, 2023). Sleep disorders are present in 80% of autistic children and 50% of autistic adults (Lane et al., 2022). Common sleep issues reported are prolonged sleep latency, reduced duration of sleep, and waking during sleep (Lane et al., 2022). These common sleep issues have been associated with an increase in physical aggression, inattention, oppositional behavior, tantrums, self-injury, and mood variability in the ASD population (Seo, 2021). Weighted devices such as weighted blankets, compression t-shirts, and garments are becoming a popular discussion for improving sleep for individuals with ASD. In theory, weighted devices such as weighted blankets create a deep pressure sensation that decreases one’s physiologic level of stress and arousal, potentially improveing sleep quality (Bolic Baric et al., 2021). Despite the increasing popularity of weighted devices, it remains unclear how effective these weighted devices are in reducing sleep disturbances for individuals with ASD.

Did physical aggression in women increase during the novel coronavirus 2019 (COVID-19) pandemic? A perspective of facial trauma.

PurposeThe present study aimed to assess whether there was an increase in physical aggression in women treated in Belo Horizonte, Minas Gerais, through the mandatory quarantine.MethodsData from a cross-sectional study were collected and analyzed, from March 1 to December 31, 2020. Additionally, data from the same period the previous year were collected for comparison.ResultsOf the etiologies reviewed for 2020, physical aggression had the highest percentage increase (+ 4.9%) and was the only etiology that showed a significant difference (p = 0.045). The mean age of the included patients was 34.05 years in 2019 and 33.97 in 2020, and most of the women had facial fractures, with nasal fractures being the most frequent, followed by jaw fractures. There was a significant increase (p = 0.34) in the conservative treatment of fractures from 2019 (48.6%) to 2020 (71.7%) and a minor (p = 0.088) increase in aggression toward intimate partners (2019, 40.9%; 2020, 63.9%).ConclusionPhysical aggression against women increased during the period of mandatory social isolation that resulted from the COVID-19 pandemic. Health professionals, including emergency services professionals, must be trained to identify victims and refer them to specialized care.

The development of forms and functions of aggression during early childhood: A temperament-based approach.

This study used a short-term longitudinal design with theoretically derived preregistered hypotheses and analyses to examine the role of temperament in the development of forms (i.e., physical and relational) and functions (i.e., proactive and reactive) of aggressive behavior in early childhood (N = 300, M age = 44.70 months, SD = 4.38, 44% girls). Temperament was measured via behavioral reports of emotional dysregulation, fearlessness/daring, and rule internalization/empathy and, in a subsample that completed a physiological assessment, via skin conductance and respiratory sinus arrhythmia. Emotion dysregulation generally served as a risk factor for all subtypes of aggression, with evidence of stronger associations with reactive as compared to proactive functions of relational aggression for girls. Daring predicted increases in physical aggression, especially among boys, and rule internalization predicted decreases in relational aggression, especially among girls. Rule internalization mediated longitudinal associations between daring and proactive relational aggression for girls. Some evidence also emerged supporting associations between adaptive functioning (i.e., high empathy, high respiratory sinus arrhythmia) and proactive functions of aggression. Findings highlight distinct temperamental risk factors for physical versus relational aggression and provide partial support for gender-linked theories of the development of aggression.

Female Aggression: Evolution’s Not So Secret Weapon

In the present article, we examine the relatively recent and substantial increase in physical aggression among adolescent females. We review what is known about the prevalence and specific characteristics of aggression among adolescent females, and then propose a novel way of understanding this behavior. Existing evidence from multiple academic disciplines is reviewed and integrated to propose a new framework for considering the underpinnings of physical aggression in females. Most examinations of physical aggression in females have focused on non-human animal models of maternal aggression. In spite of this, the growing prevalence of physical aggression among adolescent females continues to be poorly understood. We endeavor to integrate multiple viewpoints on female aggression and posit a conceptualization of female aggression among adolescents that reflects an immature, socially inexperienced, precursor to functional maternal aggression.

Physical Aggression and Coronary Artery Calcification: A North Texas Healthy Heart Study.

The purpose of this study was to determine the association between aspects of hostility and coronary artery calcification (CAC) scores. Specifically, analyses differentiated between subtypes of hostility and their relation to CAC. A sample of 571 patients aged 45 or older with no history of cardiovascular disease completed assessments of demographic, psychosocial, and medical history, along with a radiological CAC determination. Logistic regression was used to determine the association between hostility and CAC. Hostility was measured using the Aggression Questionnaire, which measured total aggression and how aggression is manifested on four scales: Physical, Verbal, Anger, and Hostility Aggression. Regression analyses indicated that only the physical aggression parameter was related to CAC: a 5% increase in odds of CAC presence was indicated for every point increase in physical aggression. The association remained significant in adjusted analyses. Other factors associated with CAC in adjusted analyses included: age, gender, race/ethnicity, BMI, and dyslipidemia. Psychosocial factors, such as physical aggression, are emerging factors that need to be considered in cardiovascular risk stratification.

Peer victimization and changes in physical and relational aggression: The moderating role of executive functioning abilities.

This study is the first to examine whether executive functioning (EF) abilities moderate longitudinal associations between peer victimization and engagement in physically and relationally aggressive behavior. Participants were 61 children (9-13 years, M = 10.68, SD = 1.28; 48% male) drawn from a partially clinical sample who were assessed at two time points, approximately 12 months apart. At time 1, children were administered a battery of EF tests; adult reports of children's relational and physical victimization and use of relational and physical aggression were collected. At time 2, adult-reported aggression was re-collected. Regression analyses tested whether EF ability moderated the association between peer victimization and increased engagement in aggression. Form-specific (e.g., physical victimization predicting physical aggression) and cross-form (e.g., physical victimization predicting relational aggression) models were tested. EF moderated the association between physical victimization and increases in physical aggression over time and between relational victimization and increases in relational aggression over time. Physical victimization predicted increases in physical aggression only among children with poor EF. However, relational victimization predicted increases in relational aggression for children with good EF skills but decreases in relational aggression for children with poor EF skills. Interaction effects for cross-form models were not significant. Results suggest that there are distinct risk factors implicated in children's engagement in physical and relational aggression. Established cognitive vulnerability models for engagement in physical aggression should not be assumed to apply to engagement in relational aggression.

Prenatal Reflective Functioning and Development of Aggression in Infancy: the Roles of Maternal Intrusiveness and Sensitivity

Maternal reflective functioning (RF) has been associated with quality of parent-child interactions and child development. This study investigated whether prenatal RF predicted the development of infant physical aggression and whether maternal sensitivity and/or intrusiveness mediated or moderated this association. The sample consisted of 96 first-time mothers (M = 22.57 years, SD = 2.13) and their infants (54 % male). Prenatal RF was measured with an interview, maternal behavior was observed during free play at 6 months post-partum, and infant physical aggression was assessed at 6, 12, and 20 months using maternal reports. Multivariate analyses of variance showed that relatively poor prenatal RF was related to relatively high infant physical aggression. These associations were moderated by maternal intrusiveness, with significant differences in physical aggression between RF-groups reportedly only in the absence of intrusiveness. Generally, mothers reported an increase in physical aggression between 6 and 12 months, except when they had both low RF-skills and were relatively less sensitive. It is concluded that prenatal RF is associated with (development of) infant physical aggression, and may be targeted in intervention programs aimed at reducing early physical aggression. Less adequate parenting, however, may counteract the beneficial effects of good RF, or obscure insight into children’s behavioral development.

Infant externalizing behavior as a self-organizing construct.

We evaluated the extent to which the externalizing behavior construct is self-organizing in the first 2 years of life. Based on dynamic systems theory, we hypothesized that changes in physical aggression, defiance, activity level, and distress to limitations would each be predicted by earlier manifestations of one another. These hypotheses were evaluated via mothers' and fathers' reports of 274 infants' externalizing behaviors at 8, 15, and 24 months of child age. Eight-month measures of physical aggression, activity level, and/or distress to limitations explained increases in physical aggression, defiance, activity level, and distress to limitations from 8 to 15 months. Increases in defiance and activity level from 15 to 24 months were predicted by 15-month physical aggression and/or distress to limitations. These findings suggest that the externalizing behavior construct is formed by dynamic interplay among its individual elements, particularly between 8 and 15 months.

Social goals, aggression, peer preference, and popularity: longitudinal links during middle school.

Social goals are associated with behaviors and adjustment among peers. However, it remains unclear whether goals predict adolescent social development. We examined prospective associations among goals, physical and relational aggression, social preference, and popularity during middle school (N = 384 participants, ages 12-14 years). Agentic (status, power) goals predicted increased relational aggression and communal (closeness) goals predicted decreased physical aggression. Popularity predicted increases and preference predicted decreases in both forms of aggression. Goals moderated longitudinal links between aggression and popularity: Aggression predicted increases in popularity and vice versa for youth with higher agentic goals, and popularity predicted increases in physical aggression for youth with higher agentic and lower communal goals. Implications for research on social goals, aggression, and popularity are discussed.

The effects of pathological gaming on aggressive behavior.

Studies have shown that pathological involvement with computer or video games is related to excessive gaming binges and aggressive behavior. Our aims for this study were to longitudinally examine if pathological gaming leads to increasingly excessive gaming habits, and how pathological gaming may cause an increase in physical aggression. For this purpose, we conducted a two-wave panel study among 851 Dutch adolescents (49% female) of which 540 played games (30% female). Our analyses indicated that higher levels of pathological gaming predicted an increase in time spent playing games 6 months later. Time spent playing violent games specifically, and not just games per se, increased physical aggression. Furthermore, higher levels of pathological gaming, regardless of violent content, predicted an increase in physical aggression among boys. That this effect only applies to boys does not diminish its importance, because adolescent boys are generally the heaviest players of violent games and most susceptible to pathological involvement.

Effects of a Tobacco Ban on Long-term Psychiatric Patients

A total ban on all tobacco products was implemented in a diverse psychiatric institution. A post hoc evaluation examined the effect of the ban on long-term patients by comparing their characteristics the year before the ban to the year after. Several variables measuring physical health, psychiatric symptomatology, feelings of well-being, and interpersonal conflict were coded with very high reliability from health records. For the majority of patients who were in the maximum security forensic division, the tobacco ban was associated with almost no detectable ill effects with some clear benefits. Among the remainder of the long-term patients, the ban might have been associated with a temporary increase in physical aggression towards staff members. It was concluded that successful implementation, and the avoidance of ill effects, depended entirely on the success staff members had in actually preventing patient access to tobacco.

Maladaptive Peer Relationships and the Development of Relational and Physical Aggression During Middle Childhood

AbstractThis study examined the unique roles of peer rejection and affiliation with aggressive peers in the development of relational and physical aggression in a sample of 979 2nd through 4th grade children. Information about target children and their best friends’ aggression and peer rejection was gathered via peer‐nominations when the majority of children were in the 3rd grade, and again approximately one year later. Friendships were identified by having target children nominate their three best friends in their classroom. Path analyses conducted with children who had at least one reciprocated friendship revealed that peer rejection and friends’ aggression predicted changes in target children's aggression; however, the patterns of relations varied by gender and form of aggression. Higher initial levels of rejection and friends’ relational aggression predicted increases in relational aggression among girls only, whereas rejection and friends’ physical aggression predicted increases in physical aggression among boys and girls. The significance of these results for the application of peer influence theories to relational aggression, and to females, is discussed.

The Effect of an Unlocked Door on Adolescent Runaway and Aggression

Abstract Runaway behavior and physical aggression were studied in 62 adolescents in an inpatient treatment program during periods when the main door was locked and unlocked. Unlocking the door had no effect on runaway behavior but was associated with a nonsignificant increase in physical aggression. Prior history of running away was an important factor in runaway behavior, while situational factors were more important for physical aggression. We discuss these findings in terms of their meaning for staff in the operation of an adolescent inpatient service.
