Relational tools for working with mild-to-moderate couple violence: Patterns of unresolved conflict and pathways to resolution.

This article offers psychologists an insider’s view of couples’ experiences with partner violence. Eleven couples seen at a university-based family and marriage clinic provided data on escalation of violence; 10 provided data on de-escalation, with 8 common to both analyses. In the Patterns and Pathways intervention, the couples first detailed their patterns of unresolved conflict and described barriers that impeded their willingness to resolve their conflicts peacefully. The progressive stages of (a) First Signs of Conflict, (b) Stirring the Pot, and (c) Point of No Return repeat themselves if couples fail to find alternative routes to conflict resolution. In the intervention’s Pathways phase, the couples examined their strategies for interrupting these sequences and created nonviolent pathways to constructive resolution, which included (a) taking responsibility for self, (b) demonstrating respect for one’s partner, and (c) making efforts to improve communication. Psychologists can glean new perspectives from this intervention by understanding how internal experiences influence aggression in high-conflict couples, and clinicians may use it to assist couples in changing their conflict resolution methods from escalating and abusive to more constructive and respectful interactions.

Public health approaches to family maltreatment prevention: Resetting family psychology's sights from the home to the community.

The authors review recent trends within the family maltreatment research field toward a public health approach, discuss the rationale for community-level interventions for family maltreatment, and sketch the history and development of community-level prevention approaches. Next, to illustrate the both the logistic and the scientific challenges of such work, the authors discuss the development and testing of an empirically guided, research-community partnership for the prevention of family maltreatment, the United States Air Force's NORTH STAR initiative (New Orientation to Reduce Threats to Health From Secretive Problems That Affect Readiness). Finally, recommendations are made for effective and disseminable family maltreatment prevention interventions. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

唐·德里罗小说中的技术暴力与责任伦理

美国作家唐·德里罗在小说中关于技术暴力的描写可以归纳为直接性暴力、慢性暴力、类像暴力等三种形态。技术的直接性暴力指的是技术对包括人体在内的物质环境所造成的短期内可以察觉的伤害与污染，而慢性暴力指的是技术对物质环境所造成的隐性和潜伏性的破坏，类像暴力则以媒体技术对人类主观能动性构成的威胁体现出来。通过这三种暴力形态，德里罗小说对现代技术的责任伦理限度和责任伦理主体进行了思考。     

环境暴力暴露、暴力态度对社会民众心理安全感的影响

目的考察社会民众心理安全感的基本状况以及环境暴力暴露、暴力态度对民众心理安全感的影响。方法对随机抽取的278名一般社会民众开展问卷调查。结果暴力暴露与暴力态度、心理不安全感之间存在显著正相关,与心理确定感之间存在显著负相关;暴力态度与心理不安全感有显著正相关;心理不安全感与心理确定感有显著负相关。暴力态度在环境暴力暴露与心理不安全感间有显著的中介作用。结论可见减少日常环境中的暴力线索暴露,改变民众的暴力态度是维护民众心理安全感的有效手段。     

Assessing gender role of partner-violent men using the Minnesota Multiphasic Personality Inventory-2 (MMPI-2): Comparing abuser types.

This study investigated traditional masculine gender role differences between male partner abuser types using the Masculinity/Femininity subsection scales of Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Structural Summary. We examined differences between four groups of partner-violent men (borderline, antisocial, psychotic features, and nonpathological partner violent) and one group of nonpartner-violent men on five MMPI-2 subscales: Masculinity-Femininity, Gender Role-Feminine, Gender Role-Masculine, Ego Inflation, and Low Self-esteem. Results indicated that the borderline group reported the most consistent traditional feminine gender role orientation of all the groups, whereas the antisocial group reported the most consistent traditional masculine gender role orientation of all the groups. The psychotic features group reported characteristics associated with both traditional masculinity and traditional feminine gender role making it distinct among all the groups. The nonpathological intimately violent group and the nonpartner-violent group reported no extreme scores when compared with the other three groups. The borderline and antisocial groups reported significantly more exposure to family of origin violence and use of more severe forms of partner abuse than the other three partner abuse groups. Treatment implications are addressed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

"Persist. persist.": A qualitative study of women's decisions to disclose and their perceptions of the impact of routine screening for intimate partner violence.

Objective: To understand the conditions under which a group of women recruited from antenatal, mental health, and substance abuse services disclose abuse in response to routine screening for intimate partner violence and their constructions of the impact of routine screening. Method: In-depth interviews with 20 women followed up 6 months after disclosing abuse in response to screening. Results: Women were in diverse situations relating to trajectories of abuse that included continued abuse despite interventions and abuse cessation within relationship. Women disclosed their abuse after making active judgments about safety on three dimensions: from the abuser, from shame and from relinquishing control. Most women described valued impacts from screening, though this was less common for those who had previous contact with statutory agencies. The process of asking shaped constructions of abuse, giving name to it. Health workers' responses to disclosures often helped to create a sense of connection. Conclusions: These effects align with Herman's work identifying naming and reconnection as important steps in recovery from trauma. The diversity of women's situations may explain difficulties in achieving significant findings by RCTs on screening impacts. Screening can bring about important changes for some women and is not simply a strategy for identification and referral. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Domestic Violence and Employment: A Qualitative Study.

This exploratory study sought to gather detailed information about how domestic violence affects women's employment, specifically to identify the types of job interference tactics used by abusers and their consequences on women's job performance; identify and understand the context associated with disclosure about victimization to employers and coworkers; and identify the supports offered to employees after disclosure. Qualitative analyses, guided by grounded theory, revealed that perpetrators exhibited job interference behaviors before, during, and after work. Abuser tactics reduced women's job performance as measured by absenteeism, tardiness, job leavings, and terminations. Among women who disclosed victimization to employers, informal and formal job supports were offered. Workplace supports led to short-term job retention, but fear and safety issues mitigated employers' attempts to retain workers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychophysiological Profiles of Batterers: Autonomic Emotional Reactivity as It Predicts the Antisocial Spectrum of Behavior Among Intimate Partner Abusers.

On the basis of studies finding heart rate deceleration among severely violent (SV) batterers (J. M. Gottman et al., 1995) and unsuccessful psychopaths (S. S. Ishikawa, A. Raine, T. Lencz, S. Bihrle, & L. Lacasse, 2001), this study compares the physiological reactivity of SV batterers (n = 35) with low-level violent (LLV) batterers (n = 37) and nonviolent men (n = 21) during 2 laboratory tasks. Men's heart rate and skin conductance level were recorded during baseline, a conflict discussion, and a standardized anger induction. Results suggest that autonomic hyporeactivity is a risk marker for antisocial features among SV men, whereas autonomic hyperreactivity is a risk marker among LLV men. Psychophysiological responding appears to be a stronger correlate of general antisocial behavior than of intimate partner abuse. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Peace psychology for a peaceful world.

Although the literature in peace psychology has been growing rapidly, many American psychologists are unaware of how conflict is resolved and peace is conceptualized and achieved. This article reviews the long history and broadening scope of peace psychology and introduces a model of peace that is useful for organizing the literature. The model suggests that peace can be facilitated at four different points of intervention. The authors discuss relationships between positive and negative peace, structural and direct violence, and peacekeeping, peacemaking, and peacebuilding. They advance some challenges for peace psychologists and conclude that peace psychology is a crucial field for grappling with humanity's most pressing problems in the coming decades.
