外周血IL-17蛋白表达与双相躁狂破坏攻击行为的相关性

目的探讨白介素17(interleukin-17,IL-17)在外周血的蛋白表达水平及其与双相躁狂破坏攻击行为的关系。方法纳入符合DSM-IV-TR诊断标准的双相躁狂患者36名,予以锂盐联合喹硫平治疗,同时纳入性别和年龄匹配的正常对照36名。采用酶联免疫吸附法(ELISA)检测两组基线及第2、4、8周末IL-17水平。结果双相躁狂组基线、第2周末、第4周末的IL-17蛋白水平高于对照组,而第8周末与对照组差异无统计学意义(P0.05)。双相躁狂组Young氏躁狂量表(Young Mania Rating Score,YMRS)总分以及YMRS第9项破坏攻击行为评分在第2、4、8周末均显著低于基线水平(P0.05),且基线IL-17蛋白水平与该两项分呈正相关(P0.05)。结论双相躁狂可能与外周血IL-17蛋白表达水平上调相关,同时基线期IL-17蛋白表达水平与双相躁狂严重程度,尤其是攻击破坏行为的严重程度相关。     

Domain-Specific Self-Concept in Relation to Traditional and Cyber Peer Aggression

Individuals who aggress against others have been described both as having overall low self-concept and as having high, inflated self-concept. The conceptualization of self-concept as domain specific provides an alternate means to resolving this controversy. In this study, 223 middle school students completed self-report measures assessing self-concept across six domains as well as engagement in peer aggression, including cyber aggression. Hierarchical regression analyses revealed that individuals who reported engaging in higher levels of traditional and cyber peer aggression reported significantly lower self-concept in the domains of behavioral adjustment, intellectual and school status, and happiness and satisfaction. Higher levels of traditional and cyber peer aggression were not significantly related to self-concept in the domains of popularity, physical appearance and attributes, and freedom from anxiety. Implications for research and practice are discussed.     

A fatal interaction: The role of the victim and function of aggression in intrafamilial homicide

Abstract

This study examines the interaction between the victim and offender during intrafamilial homicide. It is hypothesised that in order to understand the fatal consequences of the interaction, a psychological model must take into account both the role of the victim, as either a significant person or non-significant object, and the function of the aggression, as either instrumental or expressive. The combination of these two proposed facets gives rise to four hypothesised styles of intrafamilial homicide. This hypothesis was tested by analysing 191 intrafamilial homicide cases from the Chicago HITS database. Fifty two crime-scene actions were analysed using Smallest Space Analysis which revealed four distinct thematic clusters of variables. These themes corresponded to the hypothesised facets of victim role and function of aggression. Two related to expressive acts, (a) those murders where the offender kills multiple members of his family and subsequently takes his own life, and (b) cases where the victim is not treated as a significant person in the interaction but is simply used as a target for the offender's rage. The other two relate to instrumental acts, (c) those murders that are a culmination of years of abuse in which the offender sees the killing as the only means of escape, and (d) homicides where the victim is seen as an obstacle to the offender achieving a goal and is removed.

A further test of the validity of these four themes in describing distinct forms of interaction within intrafamilial homicide was to examine the proportion of cases which could be classified according to the framework. The hypothesis that each relationship would map onto just one of the interactional styles was tested by χ² which confirmed that such exclusive relationships existed at the p < .001 level of significance. This has theoretical as well as practical implications in that in using this method of classification it may be possible to infer which family member is responsible for killing their relative.     

Consulting to residential programmes for sexually aggressive delinquents

Abstract

Delinquent adolescent boys, especially those looked after in residential settings, often have a long history of coercive antisocial behaviour. Many have a history of aggression and violence, including serious sexual offences such as rape and indecent assault. In light of the Criminal Justice Act 1991 the residential care sector will come under more pressure to accommodate sexually aggressive recidivistic delinquents. However, few staff who work in residential settings with delinquents have received training in the management and treatment of sexually aggressive behaviour. Time spent in residential care settings may therefore do little to reduce the risk of sexual aggression. This paper proposes that the assessment and management of risk is central to the effective rehabilitation of this group of young people. Based on work carried out at Glenthorne Centre a risk assessment strategy is presented consisting of several different strands: an analysis of organisational decision-making; identification of sources and types of information to inform decisions; the development and implementation of a risk assessment protocol; and staff training. A case example is used to illustrate the use of the protocol at Glenthorne.     

Social problem-solving correlates of sexual deviancy and aggression among adult child molesters

Cognitive-behavioral treatment programs for adult sex offenders often include training geared to improve a perpetrator's social problem-solving skills. However, little empirical evidence exists to date that documents the relationship between problem-solving and deviant sexual interest or behavior among child molesters. As such, this study investigated the association between problem-solving and two aspects of sexual offending—self-reported sexual deviancy and clinician-rated sexual aggression among a recruited sample of incarcerated child molesters. To minimize the potential for biased self-reports, criterion scores on a lie scale were employed to exclude individuals who might be prone to misrepresent their responses. Results indicated this sample to be characterized by significant deficits on all measures of social problem-solving as compared to the general population. In addition, a series of correlational analyses indicated that an avoidant problem-solving style was significantly associated with past sexual aggression, whereas a negative problem orientation and an impulsive/careless problem-solving style were significantly related to a measure of current sexual deviancy. Of particular interest is the finding that a rational problem-solving style (i.e., the constructive style that involves the systematic application of specific problem-solving skills geared toward identifying an effective solution) was not significantly related to either sexual offending measure. The implications of these collective results are discussed.     

Inpatient aggression by mentally ill offenders: a retrospective case-control study

A retrospective case-control study was conducted examining relationships between patients’ socio-demographic, clinical and admission characteristics and inpatient aggression. Patients aged 18–64?years with a recent offence episode, who were admitted to a regional acute mental health unit, were included as cases (N?=?82), while controls comprised the next available admission, matched for age and gender (N?=?82). The prototypical patient was a young, single male, with a diagnosis of schizophrenia, a history of substance use and previous psychiatric admissions. The majority of cases had a history of aggression and recent offences against public order. They also revealed a higher likelihood of involvement in ‘less serious’ aggressive incidents (e.g. verbal threats or demands) during the index admission. Clinically, knowledge of each patient’s recent offence history, arrival mode and observed characteristics on admission (including any verbal aggression) may be important in the management of subsequent inpatient aggression.     

Transportation and Socioemotional Well-Being of Urban Students With and Without Disabilities

This study explored the extent to which transportation difficulties were associated with social, psychological, and academic experiences of urban, at-risk students who recently experienced a school transition. Participants included 165 predominantly African American and Latino/a high school youth with and without disabilities, a critical population for community psychology to address given their likelihood of multiple marginalizations. Results suggested transportation problems within school predicted more school stressors and aggressive behavior. Transportation problems to and from school predicted fewer school resources, less school belonging, and more school stressors, anxiety, and depression. Greater time to get to school predicted fewer school resources, less school belonging, and more depressive symptoms. This study demonstrates the importance of including transportation in how the school day is conceptualized, and offers several implications for how transportation services can be best addressed.
