A multivariate investigation of dating aggression

This study investigated the following variables for their unique and combined contributions to dating aggression: exposure to aggression in the family of origin (witnessing interparental aggression or being the victim of aggressive parenting); attitudes justifying dating aggression (when humiliated or in selfdefense); child-to-parent aggression; child sexual abuse; violent sexual victimization; alcohol use; and socioeconomic status. One hundred and eleven male and 179 female undergraduates reported on their own aggressive behaviors directed toward dating partners. Together, the predictor variables accounted for 41% of the variance in male-to-female aggression but only 16% of the female-to-male aggression. Humiliation, as a justification for dating aggression, contributes to the prediction of both males' and females' dating aggression, while self-defense, although a highly endorsed condition for justifying dating aggression, does not predict actual aggressive behavior. Exposure to interparental aggression plus the product between exposure and humiliation contribute to the prediction of males' dating aggression but exposure does not play a role in females' dating aggression. Violent sexual victimization contributes unique variance to both males' and females' dating aggression. The present data highlight the importance of examining specific circumstances under which males and females justify dating aggression and how such attitudes condoning aggression affect actual behaviors.

Childhood Abusive and Supportive Experiences, Inter-Parental Violence, and Parental Alcohol Use: Prediction of Young Adult Depressive Symptoms and Aggression

Issues in both the children of alcoholics and child abuse literatures were addressed in an attempt to disentangle the effects on young adults of growing up in alcoholic homes versus abusive homes. Using multiple regression, retrospective reports of parental abuse (emotional, physical, and sexual) and parental support (love/support, independence, and fairness), witnessing violence between parents, and parental alcohol use were used as predictor variables for outcomes noted by both literatures. When the effects of all other predictors were statistically controlled, parental alcohol use was not significantly related to depressive symptoms or aggression. Different abusive and supportive behaviors, depending on sex of parent and sex of participant, were significant predictors of both depression and aggression. Results underscore the importance of including and controlling for inter-parental violence and for different types of child abuse (especially emotional abuse) and parental supportive behaviors in investigations of outcomes related to abusive and alcoholic families. Implications for treatment of individuals from these families are discussed.     

Perception of and Satisfaction with Relationship Power,Sex, and Attachment Styles: A Couples Level Analysis

Eighty heterosexual dating couples provided information about their gender, individual histories of abuse in their current relationship, attachment styles, perception of and satisfaction with relationship power. Partner report of physical abuse was the dependent variable. APIM actor results suggest that an individual's gender interacts with perceived level of relationship power and satisfaction with relationship power for physical abuse. Both dimensions of attachment interacted with perceived relationship power for physical abuse. Partner effects were also found. One's partner's sex interacted with perceived power and satisfaction with relationship power. Finally, the partner's avoidant attachment interacted with satisfaction with relationship power. These findings generally replicate and extend the work of H. M. Ronfeldt, R. Kimerling, and I. Arias (1998, J. Marriage Fam. 60: 70–78) by showing how attachment styles, perception of relationship power, and satisfaction with relationship power are related in predicting aggression against a romantic partner.     

Violence and Aggression in the Lives of Homeless Children

The present research examined the role of violence and aggression in the lives of children in homeless families, focusing on possible connections among family violence, children's aggression, and children's problems with social isolation and rejection. Measures were obtained from structured interviews with 93 sets of mothers and children. Consistent with past research, average estimates of specific violent incidents experienced by mothers (as adults) were quite high. Measures of this family violence were reliably correlated with children's behavior problems as well as with measures of aggression in peer relationships (victimization, ease of resolving fights with friends).Finally, results of regression analyses were most consistent with a model in which family violenceand economic distress contributed to problematic aggressive behaviors among children; that aggression, in turn, appeared to lead to social isolation and avoidance. The overall results emphasized the need to address violence and aggression in any intervention programs for homeless children and families.     

两类青少年暴力犯的共情差异

探讨两类青少年暴力犯在共性上的差异,为青少年犯的分类矫治提供心理学的依据。研究方法：采用冲动性／预谋性攻击量表和人际反应性指标（台湾修订版）对北京少管所的360名青少年暴力犯进行问卷调查并作统计分析。结果：对青少年暴力犯的分类是有效的;工具性青少年暴力犯在同情关怀上的得分显著低于反应性青少年暴力犯,在身心隐忧上的得分显著高于反应性暴力犯;青少年暴力犯的攻击行为与观点采择、同情关怀呈负相关,与身心隐忧呈正相关。结论：两类青少年暴力犯在共情上存在显著差异,在分类矫治中应区别对待。     

Reassessing the alcohol-violence linkage: Results from a multiethnic city

This article examines the relationship between alcohol availability and nonlethal violence at the census-tract level in Miami, a multiethnic city with high levels of disadvantage and immigration. The effects of alcohol (total outlet rate) are considered from the perspectives of social disorganization and routine activities theories. Nonlethal violence is the average annual rates of robbery, aggravated assault, and total violence (combined aggravated assault and robbery). The analyses include corrections for spatial autocorrelation. The results show that alcohol availability has strong positive effects on rates of nonlethal violence and that the percentage of recent immigrants is also a significant positive predictor.     

Experimental results on data analysis algorithms for extracting and interpreting edge feature data for duct tape and textile physical fit examinations

A physical fit is an important observation that can result from the forensic analysis of trace evidence as it conveys a high degree of association between two items. However, physical fit examinations can be time-consuming, and potential bias from analysts may affect judgment. To overcome these shortcomings, a data analysis algorithm using mutual information and a decision tree has been developed to support practitioners in interpreting the evidence. We created these tools using data obtained from physical fit examinations of duct tape and textiles analyzed in previous studies, along with the reasoning behind the analysts' decisions. The relative feature importance is described by material type, enhancing the knowledge base in this field. Compared with the human analysis, the algorithms provided accuracies above 90%, with an improved rate of true positives for most duct tape subsets. Conversely, false positives were observed in high-quality scissor cut (HQ-HT-S) duct tape and textiles. As such, it is advised to use these algorithms in tandem with human analysis. Furthermore, the study evaluated the accuracy of physical fits when only partial sample lengths are available. The results of this investigation indicated that acceptable accuracies for correctly identifying true fits and non-fits occurred when at least 35% of a sample length was present. However, lower accuracies were observed for samples prone to stretching or distortion. Therefore, the models described here can provide a valuable supplementary tool but should not be the sole means of evaluating samples.     

Violent girls in adolescent forensic care are more often psychotic and traumatized than boys in the same level of care

Background: Most research on violent perpetrators is based on male samples. Aims: To compare girls and boys admitted to an adolescent forensic unit due to physically violent and/or sexually coercive behavior. Methods: On an adolescent forensic ward, demographics, family, treatment, crime and victimization histories, diagnose, psychiatric symptoms and violent behaviors during care of all adolescents are collected in a cumulative database. These were compared between girls and boys admitted due to violent behaviors. Results: Girls were more often diagnosed with schizophrenia group psychoses. The symptom profiles and violence risk ratings did not differ by sex. The girls were less antisocial in general. They were more suicidal and displayed more promiscuous behaviors, and they had more commonly been victims of sexual abuse. During inpatient care they displayed much more often violent and uncontrollable behaviors than the boys. Conclusion: Treatment approaches that respond to the special needs of aggressive girls are required.     

HEART RATE AND ANTISOCIAL BEHAVIOR: THE MEDIATING ROLE OF IMPULSIVE SENSATION SEEKING

Although a low resting heart rate is considered the best‐replicated biological correlate of antisocial behavior, the mechanism underlying this relationship remains largely unknown. Sensation‐seeking and fearlessness theories have been proposed to explain this relationship, although little empirical research has been conducted to test these theories. This study addressed this limitation by examining the relationship between heart rate and antisocial behavior in a community sample of 335 adolescent boys. Heart rate was measured during a series of cognitive, stress, and rest tasks. Participants also completed self‐report measures of state fear, impulsive sensation seeking, and both aggressive and nonaggressive forms of antisocial behavior. As expected, increased levels of aggression and nonviolent delinquency were associated with a low heart rate. Impulsive sensation seeking, but not fearlessness, significantly mediated the association between heart rate and aggression. This study is the first to show that impulsive sensation seeking partly underlies the relationship between aggression and heart rate, and it is one of the few to examine the mechanism of action linking heart rate to antisocial behavior. Findings at a theoretical level highlight the role of impulsive sensation seeking in understanding antisocial behavior and at an intervention level suggest it as a potential target for behavioral change.
