Direct and indirect relationships among posttraumatic stress disorder,depression, hostility,anger, and verbal and physical aggression in returning veterans

Hostility, anger, and aggression are conceptually related but unique constructs found to occur more often among veterans with posttraumatic stress disorder (PTSD) than among civilians or veterans without PTSD. However, the pathways between PTSD, depression, hostility, anger, and aggression have not been comprehensively characterized. Therefore, drawing on a sample of returning Operation Enduring Freedom/Operation Iraqi Freedom combat veterans ( N = 175; 95% male; mean age 30 years), this study sought to examine the direct and indirect relationships among PTSD, depression, hostility, anger, and four types of aggression: verbal, and physical toward self, others, and objects. Functional modeling of direct effects was done using multiple least-squares regression and bootstrapped mediation analyses were carried out to test indirect effects. Results indicate that PTSD is not the overall direct contributor to different forms of aggression, supporting the mediating role of depression and trait anger. Depression symptoms explain part of the relationships between PTSD and verbal aggression, physical aggression toward objects, and physical aggression toward self and trait anger explains part of the relationships between PTSD and verbal aggression, physical aggression toward objects, and physical aggression toward others. Our findings support the importance of assessing for anger, depression, and different types of aggression among veterans presenting for PTSD treatment to develop individualized treatment plans that may benefit from early incorporation of interventions.     

Aggression and risk‐taking as adaptive implementations of fast life history strategy

Within the evolutionary life history (LH) framework, aggression and risk‐taking are adaptive implementations of a fast LH strategy to adapt to environmental unsafety and unpredictability. Based on a longitudinal sample of 198 Chinese adolescents living in rural areas, half of whom were separated from their parents, this study tested LH hypotheses about aggression and risk‐taking in relation to safety constraints in the childhood living environments. The results showed that proxies of environmental unpredictability, including parental separation, were positively associated with aggression and risk‐taking and negatively associated with slow LH strategy, which in turn was negatively associated with aggression and risk‐taking. Children separated from their parents scored lower on slow LH strategies and higher on aggression and risk‐taking. These findings support the evolutionary assumption that human development responds to safety cues through behavioral implementations of LH strategies.     

攻击性驾驶行为的综合模型

攻击性驾驶行为的综合模型(a comprehensive model of driver aggression)将“挫折-攻击”模型与一般攻击性模型相结合, 提出个人因素与情境因素对心理过程具有交互作用, 阐明了认知评估、情绪唤醒对攻击性驾驶行为的影响机制。该模型能很好解释在道路冲突中, 驾驶员的攻击性持续升级的原因, 以及为什么在道路攻击性驾驶行为事件中, “肇事者”和“受害者”的角色模糊不清, 这有助于更好地确定攻击性驾驶行为对交通事故和道路安全的影响, 对攻击性驾驶行为的对策研究具有重要价值。     

敌意解释偏向与攻击的关系

敌意解释偏向是一种认知加工偏向, 指个体将模棱两可信息以敌意的方式进行解释的倾向, 它会对个体的攻击行为产生影响。攻击也会影响个体的敌意解释偏向:作为一种人格特质, 高攻击性使个体更容易产生敌意解释偏向; 作为一种行为反应, 攻击对敌意解释偏向具有发展和强化作用。敌意解释偏向和攻击之间可能存在循环关系。两者关系会受到性别、年龄以及人格特点等因素影响。未来研究需要改进敌意解释偏向与攻击的测量工具, 使测量更为直接、客观; 拓展两者不同亚类之间的交互研究, 以全面系统地了解两者之间的关系; 深入探究情绪在敌意解释偏向与攻击行为关系中的作用; 整合信息加工过程, 探究它们的交互作用对攻击行为的影响等。     

Why aggression?2

On the basis of a formalised view of metapsychology, the author briefly considers the problems inherent in the Freudian notion of a death drive or aggressive drive and then goes on to develop a new theoretical conception of aggression. Aggression is understood as an affect, action or affective action and, in relation to these, as an expression of the intensity with which a drive'whether it be the sexual drive with its libidinal cathexes or the self‐preservative drive with its lethic cathexes'seeks to attain its object. In this context the author regards the regulation of closeness and distance with respect to the ‘psychogeometric locus’ of the relevant drive object as being of central importance. She contends that neurotic personalities suffer from specific distortions in the perception of the psychogeometric locus of their drive objects, which may give rise to an intensification of the drive tendencies prevailing in these individuals at any given time so that these tendencies take on an aggressive character. The author presents two clinical vignettes to show how her approach allows aggression and its occurrence to be conceptualised without resorting to the idea of a primary aggressive drive, and draws attention to the resulting technical consequences for interpretation.     

Spontaneous Trait Associations and the Case of the Superstitious Banana

We explored whether spontaneous trait transference (STT) occurs in cases where inanimate objects, rather than human bystanders, are presented in the context of trait-implicative behavior. The results provide a vivid demonstration of the associability of primed trait constructs by demonstrating STT to inanimate objects to which one does not normally attribute traits (e.g., superstitious being associated with a banana). This finding is consistent with the notion that the trait associations involved in STT are formed independent of person perception processes. The implications of this finding for the types of associative processes exposed by the popular savings in relearning methodology are discussed.     

Proactive and reactive aggression among school bullies,victims, and bully‐victims

Bullies, victims, bully‐victims, and control children were identified from a sample of 1062 children (530 girls and 532 boys), aged 10 to 12 years, participating in the study. Their reactive and proactive aggression was measured by means of peer and teacher reports. Peer and teacher reports were more concordant with respect to reactive than proactive aggression. Comparing the children in different bullying roles in terms of their reactive and proactive aggression, bully‐victims were found to be the most aggressive group of all. For this group, it was typical to be highly aggressive both reactively and proactively. Although bullies were significantly less aggressive than bully‐victims, they scored higher than victims and controls on both reactive and proactive aggression. However, observations at the person level, i.e., cross‐tabulational analyses, indicated that bullies were not only overrepresented among children who were both reactively and procatively aggressive but also among the only reactively aggressive as well as the only proactively aggressive groups. Victims scored higher than control children on reactive aggression, but they were not proactively aggressive. Furthermore, even their reactive aggression was at a significantly lower level than that of bullies and bully‐victims. Aggr. Behav. 28:30–44, 2002. © 2002 Wiley‐Liss, Inc.
