Behavior and symptoms seen in 48 24-h periods preceding violent episodes and 93 control observations were studied. Six behaviors were more common before violence: confusion, irritability, boisterousness, physical threats, verbal threats and attacks on objects.

Recent research reveals that playing prosocial video games increases prosocial cognitions, positive affect, and helpful behaviors [Gentile et al., 2009; Greitemeyer and Osswald, 2009, 2010, 2011]. These results are consistent with the social-cognitive models of social behavior such as the general learning model [Buckley and Anderson, 2006]. However, no experimental studies have examined such ef...

Earlier studies have linked lipid metabolism to suicide and impulsive-aggressive behaviors. We previously reported that suicide attempters had significantly lower leptin and cholesterol levels than controls. Since lower cholesterol levels have been related to violence alone, we decided to evaluate serum total cholesterol and leptin levels in violent and non-violent suicide attempters. In the pr...

Observing violent content has been hypothesized to facilitate antisocial behaviors including interpersonal violence. Testosterone is released in response to perceived challenges of social status, often followed by an increase in aggressive behaviors and physiological activation. Prior investigations evaluating the impact of observing violence on autonomic function have focused on sympathetic me...

Deliberate self-harm behavior (DSH) can have profound effects on a person's quality of life, and challenges the health care system.

This study aims to (1) specify the prevalence and character of DSH, (2) identify clinical, neurocognitive, psychosocial...

This study investigated the long-term relationship between abusive parenting and adolescent mental health, and the path to delinquent behavior. Longitudinal data from 5th through 7th graders from the Korean Children and Youth Panel Survey (KCYPS) were analyzed to examine if abusive parenting was a predictor of early adolescent delinquency behavior, via aggression and depression as mediating fac...
