Family features and characteristics are often identified as central to the development of antisocial behavior and are thus attractive targets for risk-focused preventive intervention. Using meta-analytic techniques, we examined the covariation between 21 family constructs with the current or later display of problem, aggressive, criminal, or violent behaviors. The 80 mean relationships, based on 3,124 correlations from 233 reports of 119 longitudinal studies, discussed in this paper are generally moderate, with a grand mean across outcomes of [`(rx,y)] = .15 \overline {{r_{x,y}}} = .15 . Family constructs were most predictive of problem behaviors, [`(rx,y)] = .21 \overline {{r_{x,y}}} = .21 . Predictors measured earlier in life were significantly stronger in 12 relationships and significantly weaker in 18 relationships. These findings are discussed with reference to Rutter’s (American Journal of Orthopsychiatry 57:316–331, 1987) conceptualization of protective mechanisms which suggests that if family factors warrant the attention they have engendered, then it is through their interaction with other developmental and situational factors.  相似文献

To investigate gender and ethnic differences in experiences of violence, 415 Black and White males and females were asked about some of their aggressive behaviors in the past. In their most aggressive encounters, males were more likely than females to have received and instigated physical violence and females to have experienced violence in a sexual context; same-sex aggression was more common than cross-sex violence. More males than females had urged or screamed at others to be more aggressive, with males more likely to incite other males and females to urge other females to be aggressive. Males were more likely than females to have last been angry with a male, and a number of sex differences were found in the behaviors exhibited when last angry. Although positive consequences of aggression did not differ significantly by sex, females were more likely to have experienced negative interpersonal effects of behaving aggressively and males to have suffered physical harm or legal troubles. Relatively few differences between Black and White subjects were found, but Black males were more likely than Whites to keep their anger to themselves and to get the target in trouble; White males were more likely to yell at the target and tell the target of their anger. White females were more likely than Blacks to get the target in trouble. In general, the results are consistent with sex role stereotypes and suggest that the experiences of aggression and responses to anger may be substantially different for males and females.  相似文献

Previous research indicates that observation of marital violence has a deleterious impact on children's adjustment. However, little is known about the mechanisms underlying this relationship. The present study examined the relationships between observation of marital violence, mother-child aggression, father-child aggression, and child behavior problems in a sample of 185 children (ages 7 to 13) and their mothers who were residing at battered women shelters. A significant positive association was found between amount of marital violence witnessed and father-child aggression. However, the correlation between the amount of marital violence witnessed and mother-child aggression was not significant. Hierarchical regression analyses revealed that both the amount of marital violence witnessed as well as mother-child aggression were significantly related to child behavior problems, even when controlling for the effects of child age, race, and father status (i.e., whether the mother's partner was the biological father or stepfather/cohabitee). Family violence variables were better predictors of girls' rather than boys' behavior problems, particularly externalizing behavior problem scores. The lack of significance between father-child aggression and child behavior problems, as well as the implications of the findings, are discussed.  相似文献

Seventy per cent of general practitioners (GPs) were found in an earlier study to have been subject to aggressive/intrusive behaviours by patients, with nearly 20% stalked and 20% harassed. Using the same sample, an exploration was undertaken of patterns of behaviour, patient characteristics, including mental illness and motivation, GP characteristics, and effects upon them of aggression/intrusion. There were significant differences in patterns of behaviour between stalking and harassment. Nearly half the patients involved were suspected to be mentally ill, including 54.5% of stalking cases. Stalking was significantly associated with intimacy-seeking motivation, and harassment with resentful motivation. No significant associations emerged between sex of patients or GPs and aggressive/intrusive behaviours. Measures of GP time-at-risk were associated with higher prevalence of individual behaviours. GPs’ responses to aggressive/intrusive behaviours included increasing security and changing routines, with small minorities afraid to go out or be at home alone, and a proportion experiencing adverse effects on personal relationships.  相似文献

Numerous studies uncover a link between cognitive skills and adolescent violence. Overlooked is whether the relationship changes at varying levels of neighborhood disadvantage. We examine the issue by contrasting two models that place individual difference in cognitive skill within a social‐structural framework. Using five waves of the 1997 National Longitudinal Survey of Youth and a three‐level hierarchical model, results indicate that cognitive skill is inversely associated with violence and that the relationship is strongest in non‐disadvantaged neighborhoods. However, the cognitive skills–violence relationship is indistinguishable from zero in the most disadvantaged neighborhoods. The findings are therefore consistent with the hypothesis that social expression of developed ability is muted in disadvantaged contexts.  相似文献

The objective was to evaluate a new scale aimed at assessing antisocial attitudes, the Pro-bullying Attitude Scale (PAS), on a group of 259 voluntarily-recruited male juvenile delinquents from a juvenile correctional institution in Arkhangelsk, North-western Russia. Exploratory factor analysis gave a two-factor solution: Factor 1 denoted Callous/Dominance and Factor 2 denoted Manipulativeness/Impulsiveness. Subjects with complete data on PAS and Childhood Psychopathy Scale (CPS) (n = 171) were divided into extreme groups (first and fourth quartiles) according to their total scores on PAS and the two factor scores, respectively. The extreme groups of total PAS and PAS Factor 1 differed in CPS ratings and in violent behavior as assessed by the Antisocial Behavior Checklist (ABC). They also differed in the personality dimension Harm Avoidance as measured by use of the Temperament and Character Inventory (TCI), and in delinquent and aggressive behavior as assessed by the Youth Self Report (YSR). The extreme groups of PAS Factor 2, in turn, differed in aggressive behavior as assessed by the YSR, and in the TCI scale Self-Directedness. When PAS was used as a continuous variable, total PAS and PAS Factor 1 (Callous/Dominance) were significantly positively related to registered violent crime. The possible usefulness of PAS in identifying high-risk individuals for bullying tendencies among incarcerated delinquents is discussed.  相似文献

Previous studies have reported numerous correlations between psychopathy and various personality traits, behavioural tendencies or clinical characteristics. The present study examined in greater depth the relationships between the components of psychopathy as measured by the Psychopathy Checklist—Revised (PCL-R) and intelligence as well as impulsivity. A total of ninety male violent offenders were recruited from a prison and a forensic–psychiatric hospital in Germany. All of the subjects were assessed using the PCL-R, the Barratt Impulsiveness Scale (BIS-11), and a short version of the German Wechsler Adult Intelligence Scale (WIP). As expected, a canonical correlation analysis showed a negative association between spatial intelligence and the Factor 2 subtotal on the PCL-R (reckless lifestyle/antisociality). In addition, our results agreed with the assumption of an association between impulsivity and the subtotal for PCL-R Factor 2. The positive relationship between verbal intelligence and the subtotal for Factor 1 of the PCL-R (insincere, manipulative conduct/affective deficits) vanished after controlling for educational level. The results indicate that there is a relationship between the spatial components of intelligence and the concept of psychopathy as described by Hare. This result supports the spatial impairment aetiological model of antisocial behaviour.  相似文献

Abstract

Until recently, relatively little attention has been paid to young children who are sexually aggressive to other children. In this paper, cognitive-behavioural group techniques which have been used in the treatment of aggressive, impulsive behaviour in young children were applied in a small group setting to the sexually aggressive behaviour of pre-pubescent boys. The boys initially learned a ‘Stop and Think” model for general interpersonal problem-solving, which was then used to work on their difficulties with verbal and physical sexual aggression. Observation of the children's behaviour, reports from carers, school staff and social workers indicated that the group programme increased the children's ability to inhibit impulsive, aggressive behaviour. In the nine months after the group finished there were no known incidents of sexual aggression. In the context of certain limitations discussed in the paper, this positive outcome suggests that these methods have potential for reducing the likelihood of sexually aggressive behaviour becoming habitual.  相似文献

Video games often feature a character that evolves into an iconic superhero. In a strange twist of fate, the video game medium will have the opportunity to become a superhero itself. The recording, comic book, and movie industries have rallied around video games as the case of Arnold Schwarzenegger vs. Entertainment Merchants Association and Entertainment Software Association reaches the Supreme Court of the United States. The case concerns a 2005 California ban on the sale of violent video games to minors. The law was later overturned by the District Court and the 9th Circuit Court on appeal. At issue is whether the law violates the First Amendment of the Constitution. Do video games deserve the full protection of the Constitution as a legitimate form of speech, or should it be limited due to its alleged effects on the psychological well-being of minors? This Article will look at the impact this case may have when it reaches the Supreme Court, an analysis of the issues that will be argued, and the history of legislation involving violent video games.  相似文献

The present experiment examined whether or not relatively simple cognitive and information-processing limitations may prevent us from recognizing instances of organizational discrimination. It was hypothesized that the perception of discrimination would be more difficult when the relevant information had been presented in a case-by-case basis rather than in aggregate format. The obtained results provided strong support for the original hypothesis. Subjects who had been presented with company data in aggregate format provided significantly higher ratings of discrimination than those subjects for whom the information had been presented in sequential form. The implications of these findings to the policy of affirmative action are also discussed.  相似文献

现代西方心理学在经过了行为主义、认知主义的描写后,正在接受一种新的描述方式."第二次认知革命"有可能使心理学向心理学是有关个体或者群体中的积极人的研究这一传统的、常识性观念回归.认知革命明确了一个真理,心理学应该成为对意义的心理研究.然而,在方法论上传承了行为主义的认知心理学,片面地将"意义制造"理解为"信息加工",追求心灵——"自然之镜"——中的"心理表象".话语观念的导入,使得处在语用平台上心理学家认为,语境、社会-语言的约定以及社会交换的模式,是构成意义的唯一决定因素.在这三描述方式中,对意义的理解和建构发挥着关键的作用.话语在心理现象中占有中心地位.这使我们认为,心灵是个动态的观点,植根于历史、政治、文化、社会和人际的语境之中.  相似文献

The present study examined sex differences in initiation of physical aggression as observed during discussion tasks and in the likelihood of a similar response from the partner. In addition, patterns for men and women in the prevalence of aggression initiation and partner reciprocation across 4 time points spanning approximately 9 years from late adolescence through the mid-20s are examined, as well as overall associations with reported aggression and injuries. Findings indicated that the young women were more likely than the men to initiate physical aggression at late adolescence. However, by the mid-20s in early adulthood there were no significant sex differences in initiation rates. The average rates of reciprocation across the 4 time points appeared to be similar for men and women. Women and men appeared more likely to report injuries if the couples observed involved mutual physical aggression in their interactions.  相似文献

What influence do the personal belief in a just world (i.e., the perception that one usually gets what one deserves) and different kinds of causal attributions have on adjustment to sexual violence? Using a sample of N = 62 victims of sexual aggression (mean age = 21.7) it was shown that respondents were better able to adjust to their experience of sexual violence the higher their personal belief in a just world. Moreover, the more respondents attributed their victimization to situational circumstances (external attributions) and the less they attributed their victimization to their character and personality (characterological self-attributions), the less they felt distressed by past victimization. The degree to which participants attributed their victimization to their own concrete behavior (behavioral self-attribution) was not related to their adjustment. Further analyses showed that the influence of the personal belief in a just world was mediated by the three attribution styles. Additionally, the adaptiveness of external attributions was moderated by participants’ just world belief.  相似文献
