The relationships between posttraumatic stress symptom clusters and marital intimacy among war veterans.

This study examined (a) the relationships between posttraumatic stress disorder (PTSD) symptom clusters and marital intimacy among Israeli war veterans and (b) the role of self-disclosure and verbal violence in mediating the effects of PTSD avoidance and hyperarousal symptoms on marital intimacy. The sample consisted of 219 participants divided into 2 groups: ex-prisoners of war (ex-POWs; N = 125) and a comparison group of veterans who fought in the same war but were not held in captivity (N = 94). Ex-POWs displayed higher levels of PTSD symptoms and verbal violence and lower levels of self-disclosure than did controls. Although ex-POWs and controls did not differ in level of marital intimacy, they did, however, present a different pattern of relationships between PTSD clusters and intimacy. In ex-POWs, self-disclosure mediated the relations between PTSD avoidance and marital intimacy. Verbal aggression was also found via indirect effect of hyperarousal on marital intimacy. The results point to the importance of self-disclosure and verbal violence as interpersonal mechanisms for the relations between posttraumatic symptoms on marital intimacy of ex-POWs.

Psychopathy and violence: The importance of factor level interactions.

The power of scales based on the Psychopathy Checklist (PCL; R. D. Hare, 1980) for prediction of violent behavior is well established. Although evidence suggests that this relationship is chiefly due to the impulsive and antisocial lifestyle component (Factor 2), the predictive power of psychopathy for violence may also reflect the multiplicative effects of this component with interpersonal and unemotional traits (Factor 1). The determination of the extent to which psychopathy subcomponents interact to predict violence has theoretical and practical implications for PCL-assessed psychopathy. However, the relationship between violence and the interactive effects of psychopathy subcomponents remains largely undetermined. The authors used prospective and cross-sectional designs to examine the independent and interactive effects of the factors of PCL-assessed psychopathy in 2 samples: (a) 199 county jail inmates and (b) 863 civil psychiatric patients. The Factor 1 × Factor 2 interaction predicted violence in both samples, such that the predictive power of Factor 2 was attenuated at lower levels of Factor 1.

Conceptualizing Housing Instability: Experiences with Material and Psychological Instability Among Women Living with Partner Violence

Although recent research has documented that partner violence places women at risk of homelessness and material housing instability, sparse evidence yet documents the existence or importance of psychological housing instability for this group. We draw from 45 women’s reports of their experiences of housing instability across three periods: while living with their abusive partner, immediately after leaving the partner, and long after leaving. Housing instability—material and especially psychological—was a major concern for women across all periods, along with co-occurring social, familial, financial, mental health, and violence related problems. In the absence of coordinated services models, access to and navigation of available services to address these simultaneous problems posed important challenges for these women. The concept of housing instability should be expanded to include psychological instability, and, for women who are experiencing abuse, should be considered alongside numerous social and health problems that exacerbate housing precarity.

Development of a safety awareness group intervention for women with diverse disabilities: A pilot study.

Objective: Describe the development and preliminary evaluation of a safety awareness program for women with disabilities. Design: Baseline and postintervention questionnaires administered to a sample of women who completed a safety awareness program. Participants: Seven women with diverse disabilities. Intervention: Eight interactive sessions designed to increase protective factors. Setting: Community site for persons with disabilities. Main Outcomes: Safety self-efficacy, safety skills, social support/isolation, and safety promoting behaviors. Results: Significant increases from baseline to postintervention were found on measures of self-efficacy and safety skills. Although not statistically significant, improvements were also found in safety promoting behavior. Conclusion: Despite the small sample, findings suggest that participation in a safety awareness program may improve protective factors.

The mediating role of empowerment for African American women experiencing intimate partner violence.

Intimate partner violence (IPV) is a significant societal problem associated with posttraumatic stress disorder (PTSD) and depression, which in turn can cause impairment in a variety of areas. Previous research suggests that African American women experience more frequent and severe IPV than White women, yet report fewer PTSD symptoms related to their abuse. One proposed explanation for this relationship is that African American women are more resilient due to internal coping methods such as empowerment; however, this relationship has yet to be empirically tested. The current study investigates the role of empowerment in mediating IPV-related psychological distress in a sample of African American and White battered women (N = 204). As hypothesized, personal empowerment mediated the relationships between race and PTSD and race and depression, suggesting that empowered African American women may demonstrate greater resiliency when faced with IPV. Results are discussed in terms of their implication for developing culturally sensitive empowerment-based interventions for battered women.

Making sense of family conflict: Intimate partner violence and preschoolers’ externalizing problems.

This research examines relations among parental intimate partner violence (IPV), preschoolers’ narrative coherence about family conflict situations, and preschoolers’ externalizing problems. Participants were 57 mothers and their 4- to 5-year-old children. Mothers provided data on IPV and children’s externalizing problems. Narrative coherence was coded from children’s play narratives in response to story stems from the MacArthur Story Stem Battery. Results are consistent with theory suggesting that exposure to IPV may adversely affect preschoolers’ ability to understand family conflict situations in an organized manner, which in turn may contribute to their externalizing problems.

Predictors of domestically violent men's aggression toward children: A prospective study.

This research examines predictors of domestically violent men's aggression toward children after the children and their mothers sought help at an emergency shelter for domestic violence victims. Participants were 62 women who had sought refuge at a domestic violence shelter and who had at least one child between 4 and 9 years old. During their shelter stay, women provided data on partner–child aggression that occurred before shelter entry. After leaving the shelter, they also provided data on postshelter partner–mother intimate partner violence (IPV), children's postshelter contacts with their mothers' partners, and postshelter partner–child aggression on 5 occasions after their shelter departure (4, 8, 12, 16, and 20 months postshelter). Consistent with our hypotheses, the level of partner–child aggression before the family entered the shelter, the level of partner–mother IPV after shelter departure, and the frequency of children's contacts with the partners after shelter departure each predicted postshelter partner–child aggression. Clinical and policy implications are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
