Purpose: Between 2000 and 2012, the incident dialysis population in the United States increased by nearly 60%, most sharply among adults 75 years and older. End-of-life (EOL) conversations among dialysis patients are associated with better patient-centered outcomes and lower use of aggressive interventions in the last month of life. This study examined how health literacy may affect engagement, comprehension, and satisfaction with EOL conversations among elderly dialysis patients. Design and Methods: Qualitative/descriptive study with semi-structured interviews about health literacy, EOL conversations, and goals of care with 31 elderly dialysis patients at 2 centers in Boston...

Group housing is highly important for social animals. However, it can also give rise to aggression, one of the most serious welfare concerns in laboratory mouse husbandry. Severe fighting can lead to pain, injury and even death. In addition, working with animals that are severely socially stressed, wounded or singly-housed as a result of aggression may compromise scientific validity. Some general recommendations on how to minimize aggression exist, but the problem persists. Thus far, studies attempting to find solutions have mainly focused on social dominance and territorial behavior, but many other aspects of routine housing and husbandry that might influence aggressive behavior have been overlooked...

Understanding how social experiences are represented in the brain and shape future responses is a major challenge in the study of behavior. We addressed this problem by studying behavioral, transcriptomic and epigenetic responses to intrusion in honey bees. Previous research showed that initial exposure to an intruder provokes an immediate attack; we now show that this also leads to longer-term changes in behavior in the response to a second intruder, with increases in the probability of responding aggressively and the intensity of aggression lasting two and one hours, respectively...

In recent years there has been much interest in investigating the social structure of group living animals using social network analysis. Many studies so far have focused on the social networks of adults, often excluding younger, immature group members. This potentially may lead to a biased view of group social structure as multiple recent studies have shown that younger group members can significantly contribute to group structure. As proof of the concept, we address this issue by investigating social network structure with and without juveniles in wild olive baboons (Papio anubis) at Gashaka Gumti National Park, Nigeria...

Firearm violence has been the second leading cause of death among adolescents and young adults in the United States since 2000 and is a major public health concern. But firearms may be related to less lethal forms of violence as well. Here we examine the relationship between the presence of a gun in the home and several behavioral and psychosocial measures related to aggression and violence among adolescents using data from a community-based survey of nearly 2,000 youths living in low-income neighborhoods. Our results indicate that adolescents living in homes where a gun is present display more aggressive attitudes and behaviors than their counterparts living in homes with no gun present...

Traumatic brain injury (TBI) represents a major public health problem, which is associated with neurological dysfunction. In severe or moderate cases of TBI, in addition to its high mortality rate, subjects may encounter diverse behavioral dysfunctions. Previous reports suggest that an association between TBI and chronic pain syndromes tends to be more common in patients with mild forms of brain injury. Despite causing minimal brain damage, mild TBI (mTBI) often leads to persistent psychologically debilitating symptoms, which can include anxiety, various forms of memory and learning deficits, and depression...

Although the assessment of empathy has moved from general empathy to differentiating between cognitive and affective empathy, no instruments have assessed somatic (motor) empathy, and none have separated positive from negative affect empathy. The main objective of this study was to develop a 30-item self-report cognitive, affective, and somatic empathy scale (CASES) with positive and negative affect components for use with children and adolescents. A community sample of 428 male and female 11-year-olds completed the CASES together with validity questionnaires and were assessed on IQ...

Yawning is a multifunctional behavior with a role in social communication. In Old World monkeys, the "tension yawn" is often used as a threat, allowing individuals to completely expose their canines. To explore the role of this phenomenon, we selected 2 closely related species-Japanese macaques (Macaca fuscata) and Tonkean macaques (M. tonkeana)-which differ primarily in terms of their tolerance levels. Japanese macaques are classified as despotic; Tonkean macaques are classified as tolerant. Both species live in multimale-multifemale societies, show a high level of sexual dimorphism, and have comparable yawning repertoires that include displaying a covered teeth yawn and an uncovered gums yawn...

Conspecific aggression in outdoor-housed rhesus macaques (Macaca mulatta) at primate research facilities is a leading source of trauma and can potentially influence animal wellbeing and research quality. Although aggression between macaques is a normal part of daily social interactions, human presence might affect the frequency of various behaviors and instigate increases in conspecific aggression. We sought to determine how and which human management events affect conspecific aggression both immediately after an event and throughout the course of a day...

Coping Power is an evidence-based preventive intervention program for youth with aggressive behavior problems that has traditionally been delivered in small group formats. Because of concerns about iatrogenic effects secondary to aggregation of high risk youth, the current study examined whether genetic risk may moderate intervention outcome when youth were randomly assigned to group versus individual formats of an intervention. The oxytocin receptor gene (OXTR) has been associated with social behavior and may influence susceptibility to social reinforcement in general and deviant peer influence in particular...

Many species engage in mutualistic relationships with other species. The physiological mechanisms that affect the course of such social interactions are little understood. In the cleaning mutualism, cleaner fish Labroides dimidiatus do not always act cooperatively by eating ectoparasites, but sometimes cheat by taking bites of mucus from so-called "client" reef fish. The physiological mechanisms in these interspecific interactions, however, are little studied. Here, we focussed on three neuromodulator systems known to play important roles in intraspecific social behaviour of vertebrates to examine their role in clients' interspecific behaviour...

OBJECTIVE: No prior study appears to have focused on predictors of suicide in the general patient population admitted to psychiatric acute wards. We used a case-control design to investigate the association between suicide risk factors assessed systematically at admission to a locked-door psychiatric acute ward in Norway and subsequent death by suicide. METHOD: From 2008 to 2013, patients were routinely assessed for suicide risk upon admission to the acute ward with a 17-item check list based on recommendations from the Norwegian Directorate of Health and Social Affairs...

Unlike any other species, humans frequently engage in altruistic behaviors by which they increase another individual's welfare even if this implies personal costs. The psychological motives underlying altruistic behaviors remain diverse, ranging from the ability to reciprocate trust and cooperation to bonding and empathizing with family members or even genetically unrelated others. This article explores the neuroendocrine architecture of altruism by emphasizing the crucial role of the evolutionarily highly conserved peptide hormone oxytocin as a modulator of cooperative behaviors including empathy-driven altruism...

The present short-term longitudinal study examined prospective associations between two forms of peer victimization (i.e., physical, relational) and both externalizing and internalizing problems in early childhood. The study assessed 97 children (42 girls; M age = 45.22 months, SD = 6.99) over the course of one school year with assessments occurring at the end of each semester (approximately 6 months apart). Multiple methods were used to collect data over the course of one school year to test theoretically driven hypotheses...

This study explored how the Pavlovian temperamental traits strength of excitation (SE) and strength of inhibition (SI) were related to rejection and aggression. We predicted that rejection would increase aggression, but that higher SE and SI would mitigate this effect. Participants (n = 117) completed Strelau and Zawadzki's (1998) Pavlovian Temperament Survey. A week later they were told that a peer wanted (acceptance) or did not want (rejection) to work with them and they were given a chance to react aggressively by damaging that person's chance of getting a job...

Autism spectrum disorders (ASD) are neuropsychiatric disorders characterized by impairment in social interactions, in verbal and non-verbal communication, and restricted and stereotyped patterns of interest and behavior within the first 3 years of life. Pharmacologic interventions may be needed for the treatment of temper tantrums, aggression, hyperactivity, and stereotypes in children with ASD. The approval of aripiprazole by the United States Food and Drug Administration (USFDA) for the treatment of temper tantrums in children and adolescents with ASD has gained increased interest for the use in these patients...

The nonapeptides isotocin (IT) and arginine vasotocin (AVT), along with their mammalian homologs oxytocin and arginine vasopressin, are well known regulators of social behaviors across vertebrate taxa. However, little is known about their involvement in paternal care. Here, we measured the effect of an IT and an AVT V1a receptor antagonist on paternal behaviors in the primarily paternal teleost Amphiprion ocellaris. We also measured the effect of the IT receptor antagonist on aggression in dyadic contests between two non-reproductive fish to assess specificity of the effect on paternal behaviors...

OBJECTIVES: The interpersonal theory of suicide posits that individuals who simultaneously experience high levels of thwarted belongingness, perceived burdensomeness, and acquired capability for suicide are at high risk for a lethal or near-lethal suicide attempt. Although supported by self-report studies, no study has examined facets of the theory experimentally. The present study aimed to examine the belongingness and capability components of the theory by testing whether experimentally manipulated social exclusion interacts with self-reported acquired capability to predict higher self-administered shock levels on a self-aggression paradigm...

Adolescence has lately been recognized as a key developmental phase during which an individual's behavior can be shaped. In a recent study with male mice varying in the expression of the serotonin transporter, escapable adverse social experiences during adolescence led to decreased anxiety-like behavior and increased exploratory and aggressive behavior compared to throughout beneficial experiences. Since in this study some behavioral tests took place with a delay of one week after the last social experiences have been made, it was not clear whether the observed effects really reflected the consequences of the experienced different social environments...

Social species in captivity may face allostatic overload due to artificial grouping and other social constraints. In rescue centres, groups of psittacines are constantly mixed due to the arrival and/or release of individuals; this procedure is potentially harmful to animal welfare. This study aimed at evaluating the possible impacts of mate replacement on the stress levels of captive blue-fronted amazon parrots (Amazona aestiva). During five weeks, we recorded agonistic interactions and dropping-glucocorticoid metabolites (GCM) concentrations of individuals allocated in a group whose members were kept constant and in a group subjected to frequent member replacement...
