Modelling the acceptance of internet sites with domestic-violence information

Both in terms of prevalence and impact, domestic violence is a significant problem in modern society. The current study investigated women's acceptance of internet sites with domestic-violence information as an additional source of support. Perceived ease of use, perceived usefulness, social influence and awareness of sites were predictors of intention to use sites. However, awareness and experience of domestic violence predicted use of sites. We argue that technology acceptance needs to be studied in the context of a detailed analysis of ‘Everyday Life Information Seeking’ to better understand acceptance and as a basis for designing effective support sites.     

The public health approach to youth violence and child maltreatment prevention at the Centers for Disease Control and Prevention.

Millions of people in the United States suffer the consequences of violence, including physical injuries, psychological trauma, and death. Solutions to violence have traditionally been reactive. Through the lens of the public health perspective, the Centers for Disease Control and Prevention (CDC) views violence as predictable based on various contributing factors, and thus as preventable. Within CDC, the Division of Violence Prevention (DVP) leads efforts to prevent injury, death, and disability, and to reduce the suffering and medical costs caused by violence. DVP employs a multidisciplinary, public health approach to identify factors associated with violence, and to develop, evaluate, and disseminate preventive interventions. Psychology is one discipline that has contributed to our approach. The authors present a series of violence prevention initiatives funded by the CDC that are framed within a public health perspective, with attention to the contributions of psychology to youth violence and child maltreatment prevention.

The impact of family and community violence on children’s depression trajectories: Examining the interactions of violence exposure, family social support, and gender.

This longitudinal study used multilevel modeling to examine the relationships between witnessing intimate partner violence (IPV), community and school violence exposure (CSVE), family social support, gender, and depression over 2 years within a sample of 100 school-aged children. We found significant between-child differences in both the initial levels of depression and the trajectories of depression; depression over time was positively associated with change in witnessing IPV and CSVE and negatively associated with change in support. Two significant 3-way interactions were found: Gender and initial support, as well as gender and initial witnessing IPV, both significantly moderated the effect of change in witnessing IPV on the children’s depression over time.

Main, mediating, and moderating effects of social support on the well-being of survivors of intimate partner violence across 2 years.

Intimate partner violence is a serious and pervasive social problem with deleterious consequences for survivors’ well-being. The current study involved interviewing 160 survivors 6 times over 2 years to examine the role of social support in explaining or buffering these negative psychological consequences. The authors examined both between- and within-persons variability to explore women’s trajectories regarding their experiences of abuse, social support, depression, and quality of life (QOL). Findings revealed the complex role of social support on women’s well-being. Evidence was found for main, mediating, and moderating effects of social support on women’s well-being. First, social support was positively related to QOL and negatively related to depression. Social support also partially explained the effect of baseline level and subsequent change in physical abuse on QOL and depression over time, partially mediated the effects of change in psychological abuse, and moderated the impact of abuse on QOL. The buffering effects of social support were strongest at lower levels of abuse. Implications for future research and intervention are discussed.

Challenges to engaging Black male victims of community violence in healthcare research: Lessons learned from two studies.

A dearth of literature exists on barriers to conducting research with Black male victims of community violence, despite the need for evidence-based postinjury interventions. This study used qualitative data from a cross-sectional interview study (n = 16) and a pilot intervention study (n = 11) conducted in Boston, MA to identify challenges and facilitators to conducting research with Black male victims of community violence, particularly with regard to recruitment and maintenance of a study sample. Qualitative methods, including Grounded Theory and ethnography, were used to analyze the data. Challenges included a fear of police involvement, an impression of “snitching” when disclosing personal information, mistrust of research motives, suspicion of the informed consent process, the emotional impact of the trauma itself, and logistical issues. Facilitators to research included monetary incentives and motivation to help oneself and others. Participant recommendations on recruitment methods relating to approach and timing are provided. Findings from this study may assist in the planning of research studies for Black male victims of community violence. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Interpersonal victimization patterns and psychopathology among Latino women: Results from the SALAS study.

[Correction Notice: An erratum for this article was reported in Vol 3(1) of Psychological Trauma: Theory, Research, Practice, and Policy (see record 2010-26899-001).

Another deficiency includes mainly using convenience and/or geographically restricted samples, which impacts the generalizability of the results. To overcome these research limitations, the Sexual Assault Among Latinas (SALAS) study aimed to evaluate the broader scope of victimization among Latino women. The study surveyed a national sample of 2,000 Latino women using random digit dial methodology. Women were asked about various forms of victimization in childhood and adulthood including physical assaults, sexual assaults, stalking, threats, and witnessed violence, as well as psychological symptomatology including depression, anxiety, anger, and dissociation. This analysis found that victimized women were more likely to experience some form of polyvictimization and/or revictimization throughout their lives, with only 36% of victimized women experiencing one form of victimization in childhood or adulthood alone. Furthermore, multiple victimization experiences significantly increased the proportion of women who experienced psychological distress symptoms in the clinical range. For almost all evaluated symptoms, the multiple forms of victimization or varying victimization patterns significantly predicted clinical levels of psychological distress over any specific form or single incident of victimization. The results suggest that victimized Latino women experience multiple forms of victimization and that the evaluation of a broader spectrum of victimization better accounts for pathological symptomatology. Clinical implications for Latino women and future research directions are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)

Violence classifications and their impact on observed relationships with key factors in young offenders.

The understanding of violent criminal behavior is hindered by definitional problems in both the legal and research communities. Different definitions of violent criminal behavior and different classifications of the severity of violence are fundamental problems that need to be resolved in order to develop better conceptual models of the precursors to criminal violence that can inform management and treatment of violent young offenders. This study evaluated 6 classifications of violent juvenile offenses derived from the legal system and published research. The authors compare frequencies from different classifications and examine the influence of classifications on observed associations with expected predictor variables. Differences in frequencies and perceived associations between classifications highlight the need to adopt a consistent method of coding violent offenses for research purposes in order to obtain valid results that are capable of informing policy, the judiciary, and the development of effective interventions. The final classification system offers a method of systematic coding based on the type, frequency, and outcome of the violent behavior that distinguishes between levels of violence severity.

The complex relationship between dependency and domestic violence: Converging psychological factors and social forces.

Research indicates that economic dependency in women and emotional dependency in men independently contribute to domestic-partner abuse risk and that high levels of emotional dependency in an abused partner may reduce the likelihood that the victimized person will terminate the relationship. An analysis of psychological factors and social forces that contribute to domestic violence suggests that multimodal intervention strategies are needed to combat this complex problem.
