Selecting outcomes for intimate partner violence intervention trials: overview and recommendations

 Intimate partner violence (IPV) is endemic in societies around the world and detrimental to women's wellbeing. Abused women are frequent users of health services. Despite the recent World Health Organization guidelines on IPV and sexual violence, we need more evidence on effective responses to women in health care settings. Developing robust evidence with potential to inform policy and clinical practice requires greater clarity and consistency across studies in the selection and use of outcomes to evaluate interventions. Drawing on systematic reviews and individual trials aimed at reducing abuse and improving women's health, we discuss critical issues in respect of outcomes. We discuss primary, secondary, intermediate and proxy outcomes and measures used to evaluate interventions for women who experience IPV. We offer recommendations about which outcomes to assess and approaches to doing so within the context of trials in health care settings. © 2014 Elsevier Ltd. All rights reserved.

Offending competency and coercive control in intimate partner violence

This paper considers some of the ways in which intervention approaches for perpetrators of intimate partner violence (IPV) might be enhanced through the explicit consideration of the offense process. It is suggested that those who are experts in perpetrating this type of violence routinely use coercive controlling violence in intimate relationships. This group, for whom violence is instrumental, are not only likely to be at highest risk of offending, but also the most difficult to treat. They are more likely to have long developmental histories of violence, hold entrenched attitudes, and utilize knowledge about the effects of intimidation to avoid detection. It is suggested that specific consideration of what is known about the causes and correlates of IPV in those who follow this approach-explicit pathway can improve the outcomes of current perpetrator behavior change programs.

Problem gambling and intimate partner violence : a systematic review and meta-analysis

This study provides a systematic review of the empirical evidence related to the association between problem gambling and intimate partner violence (IPV). We identified 14 available studies in the systematic search (8 for victimisation only, 4 for perpetration only and 2 for both victimisation and perpetration). Although there were some equivocal findings, we found that most of the available research suggests that there is a significant relationship between problem gambling and being a victim of IPV. There was more consistent evidence that there is a significant relationship between problem gambling and perpetration of IPV. Meta-analyses revealed that over one third of problem gamblers report being victims of physical IPV (38.1%) or perpetrators of physical IPV (36.5%) and that the prevalence of problem gambling in IPV perpetrators is 11.3%. Although the exact nature of the relationships between problem gambling and IPV is yet to be determined, the findings suggest that less than full employment and clinical anger problems are implicated in the relationship between problem gambling and IPV victimization and that younger age, less than full employment, clinical anger problems, impulsivity, and alcohol and substance use are implicated in the relationship between problem gambling and IPV perpetration. The findings highlight the need for treatment services to undertake routine screening and assessment of problem gambling, IPV, alcohol and substance use problems, and mental health issues and provide interventions designed to manage this cluster of comorbid conditions. Further research is also required to investigate the relationship between problem gambling and violence that extends into the family beyond intimate partners.

Cross-cultural differences in intimate partner violence and depression: a systematic review

Intimate partner violence (IPV) is a serious issue that affects women from many different cultures and contexts around the world and has serious mental health consequences such as depression. This review has systematically identified studies that have made cross-cultural comparisons of the relationship between IPV and depression. Parallel literature searches of PsychInfo, Academic Search Complete, and the Web of Knowledge were conducted for the period between January 1993 and August 2013 and reference lists of articles were scanned. Studies written in English that included a measure of depression and IPV and compared these constructs across women of different cultural groups were included. Eleven studies with a total of 33,716 participants met all the inclusion criteria. While all studies found a relationship between IPV and depression, six found that there were significant differences in IPV and depression between cultures and five indicated that there was no significant difference in this relationship between cultures. The reviewed literature suggests that where there are cross-cultural differences in the relationship between IPV and depression, factors such as help-seeking behavior, individual coping strategies, racism, identity as a wife, and cultural values are likely to play a mediating role. Future research should examine the unique contribution of these factors in alleviating depression associated with IPV within cultural groups

The health and economic benefits of reducing intimate partner violence: an Australian example.

BACKGROUND: Intimate partner violence (IPV) has important impacts on the health of women in society. Our aim was to estimate the health and economic benefits of reducing the prevalence of IPV in the 2008 Australian female adult population. METHODS: Simulation models were developed to show the effect of a 5 percentage point absolute feasible reduction target in the prevalence of IPV from current Australian levels (27%). IPV is not measured in national surveys. Levels of psychological distress were used as a proxy for exposure to IPV since psychological conditions represent three-quarters of the disease burden from IPV. Lifetime cohort health benefits for females were estimated as fewer incident cases of violence-related disease and injury; deaths; and Disability Adjusted Life Years (DALYs). Opportunity cost savings were estimated for the health sector, paid and unpaid production and leisure from reduced incidence of IPV-related disease and deaths. Workforce production gains were estimated by comparing surveyed participation and absenteeism rates of females with moderate psychological distress (lifetime IPV exposure) against high or very high distress (current IPV exposure), and valued using the friction cost approach (FCA). The impact of improved health status on unpaid household production and leisure time were modelled from time use survey data. Potential costs associated with interventions to reduce IPV were not considered. Multivariable uncertainty analyses and univariable sensitivity analyses were undertaken. RESULTS: A 5 percentage point absolute reduction in the lifetime prevalence of IPV in the 2008 Australian female population was estimated to produce 6000 fewer incident cases of disease/injury, 74 fewer deaths, 5000 fewer DALYs lost and provide gains of 926,000 working days, 371,000 days of home-based production and 428,000 leisure days. Overall, AUD371 million in opportunity cost savings could be achievable. The greatest economic savings would be home-based production (AUD147 million), followed by leisure time (AUD98 million), workforce production (AUD94 million) and reduced health sector costs (AUD38 million). CONCLUSIONS: This study contributes new knowledge about the economic impact of IPV in females. The findings provide evidence of large potential opportunity cost savings from reducing the prevalence of IPV and reinforce the need to reduce IPV in Australia, and elsewhere.

Brief report: associations between self-reported paternal relationships, anger, alcohol, and intimate partner violence in a prison sample

This study investigates the association between family relationships, anger, alcohol use, and self-reported intimate partner violence (IPV). Participants were 55 male prisoners who completed a survey about their family relationships, anger, alcohol use, and aggression. Exposure to parental IPV predicted rates of self-reported perpetration of IPV, suggesting the importance of understanding more about the developmental pathways to IPV if effective prevention, intervention, and assessment strategies are to be developed for use with this high-risk population.

Receiving care for intimate partner violence in primary care: barriers and enablers for women participating in the weave randomised controlled trial

BACKGROUND: Interventions in health settings for intimate partner violence (IPV) are being increasingly recognised as part of a response to addressing this global public health problem. However, interventions targeting this sensitive social phenomenon are complex and highly susceptible to context. This study aimed to elucidate factors involved in women's uptake of a counselling intervention delivered by family doctors in the weave primary care trial (Victoria, Australia).

METHODS: We analysed associations between women's and doctors' baseline characteristics and uptake of the intervention. We interviewed a random selection of 20 women from an intervention group women to explore cognitions relating to intervention uptake. Interviews were audio-recorded, transcribed, coded in NVivo 10 and analysed using the theory of planned behaviour (TPB).

RESULTS: Abuse severity and socio-demographic characteristics (apart from current relationship status) were unrelated to uptake of counselling (67/137 attended sessions). Favourable doctor communication was strongly associated with attendance. Eight themes emerged, including four sets of beliefs that influenced attitudes to uptake: (i) awareness of the abuse and readiness for help; (ii) weave as an avenue to help; (iii) doctor's communication; and (iv) role in providing care for IPV; and four sets of beliefs regarding women's control over uptake: (v) emotional health, (vi) doctors' time, (vii) managing the disclosure process and (viii) viewing primary care as a safe option.

CONCLUSIONS: This study has identified factors that can promote the implementation and evaluation of primary care-based IPV interventions, which are relevant across health research settings, for example, ensuring fit between implementation strategies and characteristics of the target group (such as range in readiness for intervention). On practice implications, providers' communication remains a key issue for engaging women. A key message arising from this work concerns the critical role of primary care and health services more broadly in reaching victims of domestic violence, and providing immediate and ongoing support (depending on the healthcare context).

An investigation of trauma responses to intimate partner violence

This research identified a high prevalence of posttraumatic stress, and complex trauma symptoms among victims of intimate partner violence; trauma symptoms may result from even moderate levels of violence. Exploration of the relationship between trauma symptoms and risk suggests that specific mental health treatment is indicated for this population.

Intimate partner violence perpetrator subtypes and their developmental origins: implications for prevention and intervention

Intimate partner violence (IPV) is a major issue for many Australian families and yet progress towards the development of effective prevention and behaviour change programs has been relatively slow. In this paper, it is proposed that the tendency to treat perpetrators as a homogenous group has hampered progress, and that treatment outcomes can be improved by tailoring treatment responses to a small set of personal and offence-related characteristics. It explores the developmental origins and trajectories of these presentations and identifies some new directions for further research in this area.

Problem gambling and family violence : family member reports of prevalence, family impacts and family coping

There exists only a small number of empirical studies investigating the patterns of family violence in problem gambling populations, although some evidence exists that intimate partner violence and child abuse are among the most severe interpersonal correlates of problem gambling. The current article reports on the Australian arm of a large-scale study of the patterns and prevalence of co-occurrence of family violence and problem gambling in Australia, New Zealand and Hong Kong. The current study screened 120 help-seeking family members of problem gamblers in a range of clinical services for both family violence and problem gambling. The main results showed that 52.5% reported some form of family violence in the past 12 months: 20.0% reported only victimisation, 10.8% reported only perpetration and 21.6% reported both victimisation and perpetration of family violence. Parents, current and ex-partners were most likely to be both perpetrators and victims of family violence. There were no gender differences in reciprocal violence but females were more likely to be only victims and less likely to report no violence in comparison to males. Most of the 32 participants interviewed in depth, reported that gambling generally preceded family violence. The findings suggest that perpetration of family violence was more likely to occur as a reaction to deeply-rooted and accumulated anger and mistrust whereas victimisation was an outcome of gambler’s anger brought on by immediate gambling losses and frustration. While multiple and intertwined negative family impacts were likely to occur in the presence of family violence, gambling-related coping strategies were not associated with the presence or absence of family violence. The implications of the findings for service providers are discussed.

Understanding women's experience of sexual desire to inform scale development

Interviews with women regarding their experiences of sexual desire informed the development of the Female Sexual Desire Questionnaire. A validation sample of 741 women completed this questionnaire, with six interrelated factors found. These components of sexual desire were labelled: Dyadic Desire, Solitary Desire, Resistance, Positive Relationship, Sexual Self-image, and Concern. The portfolio concludes that a standard evaluation process is needed to assess the effectiveness of men's behaviour change groups (MBCGs), and that such programs should comprise only one component of a comprehensive multifaceted intervention strategy against intimate partner violence (IPV). Four case studies are presented.

Cruelty to animals and psychosocial adjustment among Chinese children

Childhood cruelty to animals is associated with interpersonal violence in later life. The study for this thesis investigated risk factors for childhood cruelty to animals in China. For both boys and girls externalising problems, poor communication within families, and harsh parental discipline predicted animal cruelty, providing targets for intervention to prevent later violence. The portfolio presents four clinical case studies which demonstrate the complex and varied impact that intimate partner violence has on women, and the importance of psychological intervention in assisting women to manage their physical and mental health and well-being.

The societal benefits of reducing six behavioural risk factors : an economic modelling study from Australia

Background
A large proportion of disease burden is attributed to behavioural risk factors. However, funding for public health programs in Australia remains limited. Government and non-government organisations are interested in the productivity effects on society from reducing chronic diseases. We aimed to estimate the potential health status and economic benefits to society following a feasible reduction in the prevalence of six behavioural risk factors: tobacco smoking; inadequate fruit and vegetable consumption; high risk alcohol consumption; high body mass index; physical inactivity; and intimate partner violence.
Methods
Simulation models were developed for the 2008 Australian population. A realistic reduction in current risk factor prevalence using best available evidence with expert consensus was determined. Avoidable disease, deaths, Disability Adjusted Life Years (DALYs) and health sector costs were estimated. Productivity gains included workforce (friction cost method), household production and leisure time. Multivariable uncertainty analyses and correction for the joint effects of risk factors on health status were undertaken. Consistent methods and data sources were used.
Results
Over the lifetime of the 2008 Australian adult population, total opportunity cost savings of AUD2,334 million (95% Uncertainty Interval AUD1,395 to AUD3,347; 64% in the health sector) were found if feasible reductions in the risk factors were achieved. There would be 95,000 fewer DALYs (a reduction of about 3.6% in total DALYs for Australia); 161,000 less new cases of disease; 6,000 fewer deaths; a reduction of 5 million days in workforce absenteeism; and 529,000 increased days of leisure time.
Conclusions
Reductions in common behavioural risk factors may provide substantial benefits to society. For example, the total potential annual cost savings in the health sector represent approximately 2% of total annual health expenditure in Australia. Our findings contribute important new knowledge about productivity effects, including the potential for increased household and leisure activities, associated with chronic disease prevention. The selection of targets for risk factor prevalence reduction is an important policy decision and a useful approach for future analyses. Similar approaches could be applied in other countries if the data are available.

Homicide law reform in Victoria, Australia from provocation to defensive homicide and beyond

Homicide law reform surrounding the partial defences to murder currently animates legal stakeholders in Australia and the United Kingdom, particularly in relation to cases of lethal intimate partner violence. In 2005, the Victorian Government implemented a series of homicide law reforms, central to which was the abolition of the partial defence of provocation and the instatement of an offence of defensive homicide. This article, based on a larger qualitative research study with British, Victorian and New South Wales legal stakeholders, explores experiences and perceptions of reforms in Victoria. An analysis of the impact of homicide law reform, using Hudson's principles of discursiveness and reflectiveness as a framework for analysis, reveals some dissonance between the intent and outcomes of these legal reforms. This study concludes that reforms crafted to counter gender bias in the operation of homicide law have produced mixed results for female victims of intimate partner homicide and related case law.

Poster presentation for the 7th Australian Women's Health Conference

This poster presentation demonstrates the significant impact Intimate Partner Violence is having on health outcomes in Australia.  One in three Australian women will experience Intimate Partner Violence within their lifetime. Despite nurses and midwives being in an ideal position to care for women who have expereinced Intimate Partner Violence, they have not been trained to do so.  This poster outlines the issue of Intimate Partner Violence in Australia and highlights how imprtant it is that nurses and midwives are able to assess and care for women who have been victimised.  This poster also provides information about a national Australian study which commences in 2014 with the aim to promote the ability for Australian nurses and midwives to be able to assess and care for women experiencing Intimate Partner Violence.
