Dogs may cause zoonoses and damages; especially when we accept as normal some dangerous behavior, losing the perception of disease risk. The purpose of this review was to demonstrate that the presence of stray dogs as well as community dogs, are public health hazard. Through sustainable epidemiological information, we believe this measure could prevent it from spreading. Dog's aggressiveness regulates its social relationships through submission or dominance; those characteristics are difficult to be recognized by human population...

Glioblastoma multiforme (GBM) is a highly aggressive brain cancer and its survival after diagnosis is less than 2 years. Therefore, GBM patients are especially prone to co-occurring psychological conditions such as anxiety and depressive disorders. Furthermore, aggressive medical therapies affect patients' lives, undermining their sense of meaning and coherence. The main aim of this study was to determine the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) therapy on anxiety, depression and sense of coherence in patients with GBM...

Individuals with larger facial width-to-height ratios (FWHRs) are judged as more threatening, and engage in more threat-related behavior, than do individuals with smaller FWHRs. Here we identified components of threat potential that are related to the FWHR. In Study 1, the FWHR was correlated positively with physical threat potential (bicep size) in women and with both physical and psychological (anger proneness) threat potential in men. Behavioral aggression was measured in a subset of these participants using the Point Subtraction Aggression Paradigm (costly aggression) and a Money Allocation Task (non-costly aggression)...

Psychologists often argue that sex roles direct different types of socializing behaviors toward males and females and that this differential treatment, in turn, leads to sex differences in personality. Widely cited in support of this thesis has been the Fels longitudinal study finding that dependency and passivity are stable from childhood to adulthood for females only and aggressiveness and sexuality for males only. The present article explains why the type of sex differences in personality stability cited by Fels researchers actually contradicts the view that sex role expectations cause these differences...

Background/Aims: Behavioral and psychological symptoms of dementia (BPSD) are exhibited in most patients with Alzheimer disease (AD). Although white matter hyperintensity (WMH) is often observed with AD, the precise role of WMH in BPSD remains unclear. The current study aimed to identify the impact of regional WMH on specific features of BPSD in persons with mild to moderate AD and amnestic mild cognitive impairment (aMCI). Methods: A sample of 256 female outpatients with AD ( n = 217) and aMCI ( n = 39) were recruited...

Animal cruelty is a form of passive and active aggression that is largely undocumented and unreported. Given that animals are voiceless victims, we have to rely on witnesses and frontline staff (e.g., veterinarians) to report incidents of abuse, which suggests the number of convicted animal abusers is an under-representation of actual perpetrators. The primary aim of the current study was to identify the static and dynamic factors that distinguish animal abusers from non-abuse offenders (i.e., individuals who self-reported antisocial behavior, but not animal abuse), and non-offenders (i...

This study investigated the development of relational aggression (RA) in a sample of Chinese youth (N = 2,274, 52% boys) from fourth (Mage  = 10.27 years) to ninth grade. Using latent class growth analysis, four trajectories were identified for both peer- and teacher-rated RA: a no aggression trajectory, a low-increasing trajectory, a moderate-decreasing trajectory, and a chronically high trajectory. Chronically high RA showed a chronicity effect on adolescent peer acceptance, rejection, and rule-breaking behaviors...

BACKGROUND AND PURPOSE: Violence among nurses and in nursing academia is a significant issue, with attention increasingly focused on damage resulting from psychological violence, such as bullying, harassment, aggression, and incivility. Each workplace's interpretation of violence will impact individual behavior within the organization. Organizational and environmental factors can contribute to violent behaviors becoming normalized in the workplace. When violent behaviors go unconstrained, they become imbedded within the workplace culture...

Omega-3 supplementation has been found to reduce externalizing behavior in children. Reciprocal models of parent-child behavior suggest that improving child behavior could lead to improvements in parent behavior, however no study has examined whether omega-3 supplementation in children could reduce intimate partner violence or child maltreatment by their adult caregivers. In this randomized, double-blind, placebo-controlled, stratified, parallel group trial, a community sample of children were randomized to receive either a fruit drink containing 1 gm of omega-3 fats (Smartfish Recharge; Omega-3 group, n = 100) or the same fruit drink without omega-3's (Placebo group, n = 100)...

Chronic social isolation causes severe psychological effects in humans, but their neural bases remain poorly understood. 2 weeks (but not 24 hr) of social isolation stress (SIS) caused multiple behavioral changes in mice and induced brain-wide upregulation of the neuropeptide tachykinin 2 (Tac2)/neurokinin B (NkB). Systemic administration of an Nk3R antagonist prevented virtually all of the behavioral effects of chronic SIS. Conversely, enhancing NkB expression and release phenocopied SIS in group-housed mice, promoting aggression and converting stimulus-locked defensive behaviors to persistent responses...

We review the literature on aggression in women with an emphasis on laboratory experimentation and hormonal and brain mechanisms. Women tend to engage in more indirect forms of aggression (e.g., spreading rumors) than other types of aggression. In laboratory studies, women are less aggressive than men, but provocation attenuates this difference. In the real world, women are just as likely to aggress against their romantic partner as men are, but men cause more serious physical and psychological harm. A very small minority of women are also sexually violent...

Research into parenting influences on child conduct problems in Asian countries has been limited compared to that conducted in Western countries, especially with regard to interplay between parenting and callous unemotional (CU) traits (e.g., lack of guilt and empathy). This study examined associations between dimensions of aggressive parenting practices (psychological aggression, mild and severe physical aggression), dimensions of child aggression (proactive, reactive), and child CU traits, in Singapore. Participants were children and adolescents with clinic-referred externalizing problems (N = 282; 87...

The goal of this project is to develop a novel and innovative mobile solution to address behavioral and psychological symptoms of dementia (BPSD) that occur in individuals with Alzheimer's. BPSD can include agitation, restlessness, aggression, apathy, obsessive-compulsive and repetitive behaviors, hallucinations, delusions, paranoia, and wandering. Alzheimer's currently affects 5.4 million adults in the United States and that number is projected to increase to 14 million by 2050. Almost 90% of all affected with AD experience BPSD, resulting in increased healthcare costs, heavier burden on caregivers, poor patient outcomes, early nursing home placement, long-term hospitalizations, and misuse of medications...

Inspired by an evolutionary psychological perspective on the Napoleon complex, we hypothesized that shorter males are more likely to show indirect aggression in resource competitions with taller males. Three studies provide support for our interpretation of the Napoleon complex. Our pilot study shows that men (but not women) keep more resources for themselves when they feel small. When paired with a taller male opponent (Study 1), shorter men keep more resources to themselves in a game in which they have all the power (dictator game) versus a game in which the opponent also has some power (ultimatum game)...

BACKGROUND: Dementia has a huge physical, psychological, social and economic impact upon caregivers, families and societies at large. There has been a growing impetus to utilize Internet interventions given the potential scalability, and presumed cost-effectiveness and accessibility. In this paper, we describe the design of a randomized controlled trial (RCT) aiming to study the impact of online self-help programs on caregivers of people with dementia in India. The experimental group will receive an interactive training and support program and the comparison group will receive an education-only e-book...

BACKGROUND: Although research on the relation between testosterone and aggression in humans is inconclusive, guidelines (including the World Professional Association for Transgender Health Standards of Care, edition 7) have warned for an increase in aggression in transgender men taking testosterone treatment. AIMS: To investigate the association between levels of testosterone and aggression in treatment-seeking transgender people and explore the role of mental health psychopathology (anxiety and depressive symptoms) and social support in aggression in this population...

BACKGROUND: Agreement about acts of aggression in couples on the Conflict Tactics Scales (CTS-2) was evaluated. METHOD: We conducted a quota sampling method to recruit a community sample of 590 heterosexual adult couples from the Region of Madrid (Spain). RESULTS: Prevalence rates based on the maximum dyadic report identified more aggressive behaviors than did individual reports of perpetration and victimization in men and women. Partner agreement about physical and psychological aggression was significant and moderate...

People with Down syndrome (DS) are prone to develop Alzheimer's disease (AD). Behavioral and psychological symptoms of dementia (BPSD) are core features, but have not been comprehensively evaluated in DS. In a European multidisciplinary study, the novel Behavioral and Psychological Symptoms of Dementia in Down Syndrome (BPSD-DS) scale was developed to identify frequency and severity of behavioral changes taking account of life-long characteristic behavior. 83 behavioral items in 12 clinically defined sections were evaluated...

REVIEW
Andrew C Gallup, Bernhard Fink
Handgrip strength (HGS) is a robust measure of overall muscular strength and function, and has long been predictive of a multitude of health factors and physical outcomes for both men and women. The fact that HGS represents such a ubiquitous measure of health and vitality may reflect the significance of this trait during human evolution. This trait is also highly sexually dimorphic due to influences of androgenic hormones and fat-free body mass, suggesting that it has been further elaborated through sexual selection...

Mental health problems are disproportionately prevalent in forensic and correctional settings, and there have been numerous attempts to develop screening tools to evaluate individuals in such contexts. This study investigates the clinical utility of the Personality Assessment Screener (PAS; Morey, 1997), a brief self-report measure of risk for emotional and behavioral dysfunction, in a large mixed-gender offender sample (N = 1,658). The PAS is a 22-item measure derived from the Personality Assessment Inventory (PAI; Morey, 1991, 2007), a more comprehensive self-report instrument widely used to assess for psychological disturbances among forensic and correctional populations...
