Behavioral and psychological symptoms of dementia (BPSD) occur in up to 80% of AD patients and represent one of the largest factors contributing to caregiver burden. To analyze the effect of galantamine on BPSD and caregiver burden, we treated a total of 50 patients with mild AD for 12 weeks and evaluated them using the Neuropsychiatric Inventory (NPI) and Japanese version of the Zarit Caregiver Burden Interview (ZBI). We also performed regional cerebral blood flow single photon emission computed tomography (rCBF SPECT) at baseline using three-dimensional sterotatic surface projections...

A task force of experts was convened by the American Psychological Association (APA) to update the knowledge and policy about the impact of violent video game use on potential adverse outcomes. This APA Task Force on Media Violence examined the existing literature, including the meta-analyses in the field, since the last APA report on media violence in 2005. Because the most recent meta-analyses were published in 2010 and reflected work through 2009, the task force conducted a search of the published studies from 2009-2013...

BACKGROUND AND OBJECTIVES: Psychological symptoms can be associated with celiac disease; however, this association has not been studied prospectively in a pediatric cohort. We examined mother report of psychological functioning in children persistently positive for tissue transglutaminase autoantibodies (tTGA), defined as celiac disease autoimmunity (CDA), compared with children without CDA in a screening population of genetically at-risk children. We also investigated differences in psychological symptoms based on mothers' awareness of their child's CDA status...

BACKGROUND: Bullying is a major problem worldwide and Chile is no exception. Bullying is defined as a systematic aggressive behavior against a victim who cannot defend him or herself. Victims suffer social isolation and psychological maladjustment, while bullies have a higher risk for conduct problems and substance use disorders. These problems appear to last over time. The KiVa antibullying program has been evaluated in Finland and other European countries, showing preventive effects on victimization and self-reported bullying...

REVIEW
Christopher J Ferguson, Eugene Beresin
For nearly half a century, psychologists, pediatricians and psychiatrists have studied the potential impact of media violence on aggression and societal violence, particularly among youth. Despite hundreds of studies, scholars have failed to find consensus on potential effects. Nonetheless, professional organizations such as the American Academy of Pediatrics and American Psychological Association have released policy statements conclusively linking violent media to societal concerns. In reaction, some scholars have accused these professional groups of distorting evidence and failing to inform the public of the inconsistent nature of studies in this field...

Behavioral observation techniques which relate action to personality have long been neglected (Furr and Funder in Handbook of research methods in personality psychology, The Guilford Press, New York, 2007) and, when employed, often use human judges to code behavior. In the current study we used an alternative to human coding (biomechanical research techniques) to investigate how personality traits are manifest in gait. We used motion capture technology to record 29 participants walking on a treadmill at their natural speed...

Although cases of child abuse among migrant families are often reported by social media, the issue of child maltreatment among migrant families in China has received little empirical attention. This study investigated both the prevalence of child maltreatment by parents among migrant families, and the individual, family and community-level risk factors associated with child abuse in this context. A survey was conducted with 667 migrant and 496 local adolescents in Shenzhen, South China, with a stratified two-stage cluster sampling design...

Some children who bully others are also victimized themselves ("bully-victims") whereas others are not victimized themselves ("bullies"). These subgroups have been shown to differ in their social functioning as early as in kindergarten. What is less clear are the motives that underlie the bullying behavior of young bullies and bully-victims. The present study examined whether bullies have proactive motives for aggression and anticipate to feel happy after victimizing others, whereas bully-victims have reactive motives for aggression, poor theory of mind skills, and attribute hostile intent to others...

Aggression in mental health units is a significant and pervasive problem. However, the characteristics of patients associated with increased aggression propensity remain unclear and there are few attempts to expand understanding of these characteristics by drawing upon contemporary aggression theory. This study assessed the influence of interpersonal (hostile-dominance) and personality (psychopathy), General Aggression Model-specified (aggressive script rehearsal, attitudes towards violence, and trait anger), and clinical (psychiatric symptoms) factors on aggression during psychiatric hospitalization in 200 inpatients (132 men and 68 women; 19-64 years, M=38...

Meifang Wang, Li Liu
This research examined the overtime reciprocal relations between maternal and paternal harsh discipline and children's externalizing behavior. Seven hundred two father-mother dyads of children (6-9 years of age at baseline) completed measures of parental harsh discipline and children's externalizing behavior at five time points, 1 year apart. Autoregressive latent trajectory models revealed that maternal and paternal corporal punishment predicted subsequent children's externalizing behavior (parent-driven effects), whereas children's externalizing behavior predicted subsequent maternal and paternal psychological aggression (child-driven effects)...

C J Eubanks Fleming, Patricia A Resick
This study examined individual behavioral predictors of help-seeking using the frameworks of the Andersen model and thetheory of planned behavior in a sample of help-seeking female survivors of intimate partner violence (IPV). In-person interviews were conducted with 372 women (<em>M</em><sub>age</sub> = 34.41 years, 66% African American). Results indicated that variables suggested by the Andersen model, including age, depression, psychological aggression, and posttraumatic stress-related arousal symptoms, were significant predictors of help-seeking...

Past research suggests that exposure to parent psychological control and peer relational aggression and victimization experienced during adolescence is associated with relational intimate partner violence (IPV) in young adults (ages 22 to 29). However, the effects of continuities in these concerns across young adulthood have not been assessed. Relational IPV is characterized by behaviors intended to damage partner's emotional well-being and security in a romantic relationship (e.g., threatening to break up, purposefully ignoring, or causing jealousy)...

Facial expressions are important for humans in communicating emotions to the conspecifics and enhancing interpersonal understanding. Many muscles producing facial expressions in humans are also found in domestic dogs, but little is known about how humans perceive dog facial expressions, and which psychological factors influence people's perceptions. Here, we asked 34 observers to rate the valence, arousal, and the six basic emotions (happiness, sadness, surprise, disgust, fear, and anger/aggressiveness) from images of human and dog faces with Pleasant, Neutral and Threatening expressions...

BACKGROUND: Agitation in patients with dementia increases caretaker burden, increases healthcare costs, and worsens the patient's quality of life. Antipsychotic medications, commonly used for the treatment of agitation in patients with dementia have a box warning from the FDA for elevated mortality risk. Electroconvulsive therapy (ECT) has made significant advances over the past several years, and is efficacious in treating a wide range of psychiatric conditions. We provide a systematic review of published literature regarding the efficacy of ECT for the treatment of agitation in patients with dementia (major neurocognitive disorder)...

Scott O Lilienfeld
The microaggression concept has recently galvanized public discussion and spread to numerous college campuses and businesses. I argue that the microaggression research program (MRP) rests on five core premises, namely, that microaggressions (1) are operationalized with sufficient clarity and consensus to afford rigorous scientific investigation; (2) are interpreted negatively by most or all minority group members; (3) reflect implicitly prejudicial and implicitly aggressive motives; (4) can be validly assessed using only respondents' subjective reports; and (5) exert an adverse impact on recipients' mental health...

Callous-unemotional traits - the insensitivity to other's welfare and well-being - are characterized by a lack of empathy. They are characteristic of psychopathy and can be found in other anti-social disorders, such as conduct disorder. Because of the increasing prevalence of anti-social disorders and the rising societal costs of violence and aggression, it is of great importance to elucidate the psychological and physiological mechanisms underlying callousness in the search for pharmacological treatments. One promising avenue is to create a relevant animal model to explore the neural bases of callousness...

BACKGROUND: Children who engage in regular physical activity are protected from developing behavioral problems at home and school, but many children do not have the opportunity to participate in regular physical activity. The purpose of this study was to determine whether a non-curricular school-based physical activity program resulted in reductions in children's psychological problems in two domains: internalizing (e.g., depression) and externalizing (e.g., aggression) and whether these effects varied according to ethnicity, gender, and baseline psychological symptoms...

BACKGROUND: The ability to participate in valued activities, whether for work, leisure or family, is an important aspect of personal identity. In dementia, progressive memory loss means that abilities developed over a lifetime begin to be lost as well, contributing to the loss of self and identity. Some studies have reported that activities or interventions tailored to be meaningful to the person with dementia (defined as any activity important to the individual) are more effective in addressing behavioral and psychological symptoms of dementia (BPSD) and improving quality of life (QoL) than those that are not so tailored...

Psychological assessment can play an important role in informing the intervention process with child and adolescent victims of maltreatment. This study investigated the validity of the Rorschach in assessing aggressive drive derivatives using a profile-based approach, with a sample of 108 children and adolescents in foster care. Aggression indicators were derived from the work of Gacono and Meloy ( 1994 ). Latent class analysis yielded a 4-class model including gender and age as covariates. The first 2 classes were characterized by low prevalence rates across all indicators of aggression, and were distinguished primarily on the basis of participant's age...
