Effects of mother's parenting practices on child internalizing trajectories following partner violence.

Studies of children's functioning following exposure to a traumatic event rarely have investigated change over the weeks following the event, but examining recovery in the short aftermath of a traumatic event is important for understanding vulnerability to subsequent disorder, as well as the potential utility of preventive interventions. Data are reported from a short-term longitudinal study of 35 mother-child dyads over 14 weeks following exposure to an incident of severe intimate partner violence. Using a developmental-ecological framework, we proposed that maternal parenting practices would be associated with children's recovery, and that maternal distress would be associated with her parenting practices. Consistent with hypotheses, observed parenting practices at baseline predicted the trajectory of children's self-reported internalizing problems over the study period. Maternal mental health problems were associated with child depression symptoms, but not with overall child internalizing symptoms. Parenting was not associated with maternal mental health symptoms. Further studies should pay closer attention to the role of parenting in children's adjustment in the aftermath of a traumatic event. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

A randomized clinical trial to dismantle components of cognitive processing therapy for posttraumatic stress disorder in female victims of interpersonal violence.

The purpose of this experiment was to conduct a dismantling study of cognitive processing therapy in which the full protocol was compared with its constituent components--cognitive therapy only (CPT-C) and written accounts (WA)--for the treatment of posttraumatic stress disorder (PTSD) and comorbid symptoms. The intent-to-treat (ITT) sample included 150 adult women with PTSD who were randomized into 1 of the 3 conditions. Each condition consisted of 2 hr of therapy per week for 6 weeks; blind assessments were conducted before treatment, 2 weeks following the last session, and 6 months following treatment. Measures of PTSD and depression were collected weekly to examine the course of recovery during treatment as well as before and after treatment. Secondary measures assessed anxiety, anger, shame, guilt, and dysfunctional cognitions. Independent ratings of adherence and competence were also conducted. Analyses with the ITT sample and with study completers indicate that patients in all 3 treatments improved substantially on PTSD and depression, the primary measures, and improved on other indices of adjustment. However, there were significant group differences in symptom reduction during the course of treatment whereby the CPT-C condition reported greater improvement in PTSD than the WA condition.

Emotion regulation and intimate partner violence in newlyweds.

Is the inability to regulate negative emotions a risk factor for intimate partner violence (IPV)? To address this question, the authors asked 72 newlywed couples to report their levels of negative affect every day for 7 days and examined whether variability in those reports was associated with the IPV self-reported to have been perpetrated over the previous year. Although main effects of variability in both husbands' and wives' negative affect did not reach statistical significance, variability in husbands' negative affect significantly interacted with wives' reports of IPV to account for husbands' IPV, even after overall levels of husbands' negative affect, marital satisfaction, and chronic stress were controlled. Specifically, whereas variability in negative affect was unrelated to IPV among husbands with wives who reported no IPV, such variability was positively associated with the IPV perpetrated by husbands with wives who also reported having perpetrated IPV during the previous year. Although preliminary, these results support theories suggesting that the ability to regulate negative emotions may help intimates avoid perpetrating IPV, particularly when faced with a partner's IPV perpetration.

How useful are indices of personality pathology when assessing domestic violence perpetrators?

There has been considerable debate about profiling personality pathology when assessing and treating male perpetrators of domestic violence (DV). This study used the Millon Clinical Multiaxial Inventory (MCMI–III) to explore the severity and diversity of male perpetrator personality pathology and response bias in a group of DV perpetrators being assessed for a treatment program (N = 177). We analyzed the sample using the interpretive guidelines of White and Gondolf (2000); 54% of profiles in our sample fell into categories indicative of a personality disorder, and 37% of the total sample provided profiles indicative of severe personality pathology. These percentages were higher than White and Gondolf's findings but lower than some others. There was considerable diversity of personality pathology as well, supporting the contention that there is no one male DV perpetrator profile. Because of debate concerning the manner of responding on self-report instruments, we paid special attention to response biases in our sample. Twenty-six percent of our sample exaggerated (12%) or minimized (14%) their responses. We also found that response biases on the MCMI–III Modifying Indices were related to self-reported severity of psychopathology. This suggests that assessing severity of psychopathology is inadequate without reference to such biases. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Nailing the coffin shut on doubts that violent video games stimulate aggression: Comment on Anderson et al. (2010).

Over the past half century the mass media, including video games, have become important socializers of children. Observational learning theory has evolved into social–cognitive information processing models that explain that what a child observes in any venue has both short-term and long-term influences on the child’s behaviors and cognitions. C. A. Anderson et al.’s (2010) extensive meta-analysis of the effects of violent video games confirms what these theories predict and what prior research about other violent mass media has found: that violent video games stimulate aggression in the players in the short run and increase the risk for aggressive behaviors by the players later in life. The effects occur for males and females and for children growing up in Eastern or Western cultures. The effects are strongest for the best studies. Contrary to some critics’ assertions, the meta-analysis of C. A. Anderson et al. is methodologically sound and comprehensive. Yet the results of meta-analyses are unlikely to change the critics’ views or the public’s perception that the issue is undecided because some studies have yielded null effects, because many people are concerned that the implications of the research threaten freedom of expression, and because many people have their identities or self-interests closely tied to violent video games.

The effect of video game competition and violence on aggressive behavior: Which characteristic has the greatest influence?

Objective: This study is the first to our knowledge to isolate the effect of video game violence and competitiveness on aggressive behavior. Method: In Pilot Study 1, a violent and nonviolent video game were matched on competitiveness, difficulty, and pace of action, and the effect of each game on aggressive behavior was then compared using an unambiguous measure of aggressive behavior (i.e., the Hot Sauce Paradigm) in Experiment 1. In Pilot Study 2, competitiveness was isolated by matching games on difficulty and pace of action, and systematically controlling for violence. The effect of video game competition on aggressive behavior was then examined in Experiment 2. Results: We found that video game violence was not sufficient to elevate aggressive behavior compared with a nonviolent video game, and that more competitive games produced greater levels of aggressive behavior, irrespective of the amount of violence in the games. Conclusion: It appears that competition, not violence, may be the video game characteristic that has the greatest influence on aggressive behavior. Future research is needed to explore the mechanisms through which video game competitiveness influences aggressive behavior, as well as whether this relation holds in the long-term.

Looking Beyond Informality

It is all too easy to be optimistic about the economic and social future of Latin America. Daniela Fabricius , the author of 100% Favela: The Informal Geographies of Rio de Janeiro (forthcoming), calls into question architects working within the realpolitik of a globalised, post-nationalist world. Could an all too ready acceptance of existing conditions and the adoption of informality leave inhabitants short-changed? For to live informally is also to live precariously - no substitute for secure and prosperous living.     

Identifying a research gap in relation to family and domestic violence accommodation design within Victoria,Australia: A systematic review

Within Australia, domestic and family violence (DFV) is a major health and welfare issue that disproportionately impacts on women, children, and vulnerable segments of the population. This paper examines the results of a systematic literature review aimed at identifying the existing evidence base in relation to the nexus between accommodation design and the health and well-being of women seeking shelter within Victoria, Australia. The review focused on three primary questions: a. What literature currently exists in relation to the design of refuges? b. How does the design of DFV refuges impact on those within refuges? c. What methods and metrics have been used to assess the effectiveness of the design of housing interventions to support and promote agency, and better health and wellbeing?The review found that there is a significant lack of research into housing interventions for those seeking refuge. Of the 6038 records screened, only 2 studies were identified that fit within the review criteria, both of which focused exclusively on refuges within the USA. Among the very limited research that exists, there is little interrogation of the design of the refuge, nor an intersectional and geographically contextualized examination of how experiences of DFV and the shelter environment impact on wellbeing outcomes. Despite literature that demonstrates the positive impacts of well-being centered design approaches, the application of such research to the evaluation and design of DFV refuges, both within Australia and globally, remains an area in need of further research.

Social media jealousy and intimate partner violence in young adults’ romantic relationships: A longitudinal study

Social media have profoundly transformed young adults’ social interactions, especially within their romantic relationships. For instance, jealousy induced by the partner's activity on social media can cause conflicts that can escalate into controlling and aggressive behaviors. Previous cross-sectional studies show significant links between social media jealousy and intimate partner violence (IPV) perpetration. However, the directionality of these associations has not yet been examined using longitudinal designs. This study investigated the associations between social media jealousy and IPV perpetration in young adults’ romantic relationships over a year. Two samples, one composed of 111 couples (n = 222) and one composed of 286 individuals involved in a romantic relationship, completed online questionnaires at two time points over one year. Results of cross-lagged panel analyses were replicated across samples and suggested that the intra-individual association between social media jealousy and IPV perpetration is bidirectional and positive over time. Results also indicated a negative association between a person’s IPV perpetration at Time 1 and their partner’s online jealousy at Time 2. These findings highlight the reciprocal and dyadic influences of social media jealousy and IPV and provide a better understanding of the potential risks associated with social media use in young adults’ romantic relationships.
