Eating disorder behaviours can be seen as self-destructive behaviours to a great extent related to inhibited anger expression. However, a treatment protocol targeted at anger and aggression in these disorders is lacking. This paper describes a psychomotor therapy (PMT) model as a body-oriented method to help patients with eating disorders to cope with anger and aggression. They learn to see aggression as a positive, relational, body-felt experience, and to control anger expression at the right time with appropriate intensity. Our clinical experience indicates that PMT can accelerate the overall treatment process by triggering hidden feelings and thoughts and by developing expression skills. This article discusses PMT principles of aggression regulation and the methodological procedures of the intervention. Randomised controlled research is needed to validate clinical experiences.     

Brief report: The Adolescent Child-to-Parent Aggression Questionnaire: An examination of aggressions against parents in Spanish adolescents

The objective of this study was to develop a questionnaire to assess child-to-parent aggression in adolescents and to document the extent of the problem. The questionnaire developed in this study, the Child-to-Parent Aggression Questionnaire (CPAQ), includes forms of physical and psychological aggression directed at both the mother and the father. It also includes open questions about the reasons for the aggressive acts. The CPAQ was completed by a sample of 2719 adolescents (age range: 13–18 years old, 51.4% girls). Confirmatory factor analysis supported a four-factor correlated structure (physical aggression against mother, physical aggression against father, psychological aggression against mother, and psychological aggression against father). Psychological and physical aggression against the mother was more frequent than against the father. However, there were no differences with regard to severe forms of aggression. Girls scored significantly higher on all indicators of psychological aggression, including severe psychological aggression. Nevertheless, except for the prevalence of physical aggression against mothers, which was higher in females, there were no significant differences in physical aggression against parents. Finally, the reasons provided by the adolescents for the aggression included both instrumental (e.g., to obtain permission to get home late and to access their computers) and reactive reasons (e.g., anger and self-defense). These findings highlight the complexity of child-to-parent aggression in adolescence.     

The Healthy Brains and Behavior Study: objectives,design, recruitment,and population coverage

Violence is increasingly viewed as a public health issue that may be ameliorated by health‐based interventions. The Healthy Brains and Behavior Study (HBBS) aims to identify environmental and biological risk factors for aggression in late childhood and to reduce aggression through psychological and nutritional treatments. Utilizing a cross‐disciplinary collaborative research approach, the HBBS has both human and animal components. The human component has two stages consisting of risk assessment followed by treatment. The risk assessment is based on 451 community‐residing children aged 11–12 years and their caregivers, during which genetic, brain imaging, neuroendocrine, psychophysiology, environment toxicology, neurocognitive, nutrition, psychological, social and demographic risk variables are collected. Children who met criteria (N = 219) for problematic aggressive behaviors were assigned to one of four treatment groups: cognitive‐behavior therapy (CBT) alone, nutritional supplements alone, both CBT and nutrition, or treatment‐as‐usual. Treatment duration was 12 weeks and all children whether in treatment or not were followed‐up at three, six, and 12 months. The animal component assessed the effects of dietary omega‐3 fatty acids on the development of aggression. This study contributes knowledge on how biological factors interact with social factors in shaping proactive and reactive aggression and assesses the efficacy of treatment approaches to reduce childhood aggression.

Factors associated with retaliatory attitudes among African American adolescents who have been assaulted

OBJECTIVES: (a) To describe attitudes regarding retaliation among adolescents who have been assaulted. (b) To examine assault/event characteristics, personal, parental, and environmental factors associated with the retaliatory attitudes of adolescents who have been assaulted. METHODS: African American youth aged 10-15 years presenting to two large urban hospitals with peer assault injury and a parent/caregiver completed interviews in their home after their emergency department visit. RESULTS: Multivariate analyses revealed that lower SES, older age, and adolescents' perceptions that their parents support fighting were related to endorsing retaliatory attitudes. Girls who were aggressive were more likely to endorse retaliatory attitudes. However, level of aggression did not impact boys' retaliatory attitudes. Affiliating with aggressive peers influenced the retaliatory attitudes of boys, but did not influence girls' retaliatory attitudes. Overall, youths' perceptions of their parents' attitudes toward fighting had the greatest impact on retaliatory attitudes. CONCLUSIONS: Adolescents' perceptions of their parents' attitudes toward fighting may be a factor in subsequent re-injury among youth. Violence prevention and intervention efforts need to involve components that assess parental attitudes and incorporate strategies to engage parents in violence prevention efforts. In addition, interventions for youth who have been assaulted may need to incorporate some gender-specific components in order to address the unique needs of girls and boys.     

Junior staffing changes and the temporal ecology of adverse incidents in acute psychiatric wards

AIM: This paper reports an examination of the relationship between adverse incident rates, the arrival of new junior staff on wards, and days of the week on acute psychiatric wards. BACKGROUND: Incidents of violence, absconding and self-harm in acute inpatient services pose risks to patients and staff. Previous research suggests that the arrival of inexperienced new staff may trigger more adverse incidents. Findings on the relationship between incidents and the weekly routine are inconsistent. METHOD: A retrospective analysis was conducted of formally reported incident rates, records of nursing student allocations and junior doctor rotation patterns, using Poisson Regression. Variance between days of the week was explored using contingency table analysis. The data covered 30 months on 17 psychiatric wards, and were collected in 2002-2004. FINDINGS: The arrival of new and inexperienced staff on the wards was not associated with increases in adverse incident rates. Most types of incidents were less frequent at weekends and midweek. Incident rates were unchanged on ward-round days, but increased rates were found on the days before and after ward rounds. CONCLUSION: Increased patient tension is associated with raised incident rates. It may be possible to reduce incident rates by moderating stimulation in the environment and by mobilizing support for patients during critical periods.     

Impaired Hippocampal Neuroligin-2 Function by Chronic Stress or Synthetic Peptide Treatment is Linked to Social Deficits and Increased Aggression

Neuroligins (NLGNs) are cell adhesion molecules that are important for proper synaptic formation and functioning, and are critical regulators of the balance between neural excitation/inhibition (E/I). Mutations in NLGNs have been linked to psychiatric disorders in humans involving social dysfunction and are related to similar abnormalities in animal models. Chronic stress increases the likelihood for affective disorders and has been shown to induce changes in neural structure and function in different brain regions, with the hippocampus being highly vulnerable to stress. Previous studies have shown evidence of chronic stress-induced changes in the neural E/I balance in the hippocampus. Therefore, we hypothesized that chronic restraint stress would lead to reduced hippocampal NLGN-2 levels, in association with alterations in social behavior. We found that rats submitted to chronic restraint stress in adulthood display reduced sociability and increased aggression. This occurs along with a reduction of NLGN-2, but not NLGN-1 expression (as shown with western blot, immunohistochemistry, and electron microscopy analyses), throughout the hippocampus and detectable in different layers of the CA1, CA3, and DG subfields. Furthermore, using synthetic peptides that comprise sequences in either NLGN-1 (neurolide-1) or NLGN-2 (neurolide-2) involved in the interaction with their presynaptic partner neurexin (NRXN)-1, intra-hippocampal administration of neurolide-2 led also to reduced sociability and increased aggression. These results highlight hippocampal NLGN-2 as a key molecular substrate regulating social behaviors and underscore NLGNs as promising targets for the development of novel drugs for the treatment of dysfunctional social behaviors.
