Integrating the longitudinal study of intimate partner violence perpetration within life course criminology

Lead Research Organisation: Cardiff University
Department Name: Sch of Social Sciences

Abstract

Intimate Partner Violence (IPV) is abusive behaviour between (ex)partners and is a serious problem in society. Almost 1 in 4 women and 1 in 10 men experience IPV at some point in their lives, whilst it is estimated that £4 billion of public money is spent on responding to IPV annually. That said, there is clearly a pressing need to better understand IPV perpetration, one that can inform an evidence-based system of prevention and intervention. Therefore, this study will enhance our understanding of IPV perpetration by integrating two previously separate fields: IPV research and life course criminology. By doing so, this research will mark the next step in realising my ambition: to become an international research leader on policy-oriented theorization and investigation of criminal development and desistance (i.e. the process of stopping offending).
This research will make five important long-term contributions to criminological research and its practical applications.
First, by adopting the life course criminological approach this research will enhance our understanding of IPV perpetration. This research will establish general patterns in the development of IPV, and will explain the process of desistance from IPV.
Second, by integrating the study of IPV within the study of general criminal development this research will further develop the field of life course criminology. Whilst the life course criminological perspective is considered to be the main paradigm for understanding offending, to date IPV has been ignored in the development of life course criminological theory. Incorporating IPV perpetration in developmental models of criminal behaviour, then, will enhance our understanding of the development of offending and the pathways out of crime.
Third, as I am proposing to integrate two largely separate fields of criminological study, I will be able to establish a profile as a leading expert in this field. The research has a significant international component, s I aim to systematically compare datasets from the UK, the USA and the Netherlands. I aim to establish and lead the International Network on Criminal Development and Desistance: research, policy and practice (INCreDD). I will collaborate with American and Dutch experts during three overseas research visits. The findings from this research will be disseminated via publications in high-impact international journals, presentations at academic conferences, and at an international academic workshop. The research thus enables me to develop myself into an internationally recognized future research leader.
Fourth, this research employs existing international longitudinal datasets. Longitudinal data is vital for a comprehensive understanding of the development of criminal behaviour and the desistance process. As existing longitudinal datasets are generally underused, I aim to use the INCreDD network to encourage cross-national investigations of longitudinal data on criminal development and desistance. To consolidate my expertise in longitudinal data analysis I will participate in the prestigious Essex summer school.
Fifth, the research findings will be invaluable for policy makers and practitioners working in the criminal justice system, social care and the voluntary sector, whose work it is to develop and implement prevention and intervention programmes. Services to reduce IPV perpetration which are informed by academic research will affect the wellbeing of hundreds of thousands of partners and children, as well as reducing government spending. The INCreDD network will include an extensive network of policy makers and practitioners. The organisation of a dissemination event, presentations at practitioner organisations, and the distribution of research bulletins will enhance my knowledge exchange skills and will enable me to develop myself into a research leader who is able to effectively communicate with and impact on the work of policy makers and practitioners.

Planned Impact

This research will generate knowledge of characteristics of IPV perpetration, and factors that can promote the process of desistance from IPV. Therefore, the findings from this research will yield important opportunities to realize impact in terms of primary and secondary prevention (see Pathways to Impact for details). Prevention and intervention programmes that are informed by academic research are vital, as research has demonstrated that formal sanctions imposed by the criminal justice system do not have any lasting or significant impact on reducing IPV perpetration.

Government. It is estimated that nearly £4 billion of public funds annually is spent on responding to IPV, excluding costs associated with lost economic output or individual emotional costs, which are estimated at a further £12 billion (Walby 2009). The UK government (in particular the Ministry of Justice and the Home Office) will therefore benefit from reductions in IPV perpetration, which will be achieved through designing more effective prevention and intervention programmes informed by this research.

Policy makers. The findings will be relevant to the work of policy makers working in the areas of criminal justice, education, social care and public health, who make decisions about IPV related policies. These include policies regarding general prevention programmes implemented in education and prevention programmes aimed towards at-risk groups, as well as policies concerning responses to and punishment of IPV.

Criminal justice system and social care. The insights on IPV perpetration generated by this research could be used to inform and refine risk assessment tools that are being used by police, probation and social care professionals, to improve early identification of IPV perpetrators and to tailor their response to perpetrators. Enhancing early and accurate identification of at-risk individuals is crucial for delivering early intervention, thereby minimalizing chances of escalation. This search will also have important implications for organisations within the criminal justice system who deliver interventions for perpetrators, as the findings will underpin more effective intervention programmes aimed at reducing the perpetrator's abusive behaviour.

Voluntary sector. The research will inform the work of domestic abuse charities (e.g. SafeLives, Respect) that deliver prevention programmes and training for professionals who deal with IPV in their work. The voluntary sector will be able to deliver more complex prevention initiatives. Moreover, as charities often work alongside the criminal justice system to deliver interventions, the research findings will also contribute to the development of evidence-based interventions for IPV perpetrators.

Victims. Through improved prevention and intervention programmes for IPV perpetrators, the quality of life for victims of IPV will be greatly enhanced. In the UK an estimated 1.4 million women and 700,000 men suffered from IPV in 2014 (ONS 2015). Each year more than 100,000 people in the UK are at high and imminent risk of being murdered or seriously injured as a result of IPV, and more than 100 people each year are killed by their (ex)partners. Prevention and intervention programmes informed by this research will thus greatly improve the safety and wellbeing of hundreds of thousands of partners and children of IPV perpetrators.

Perpetrators. The findings will impact on the quality of life of perpetrators of IPV. Interventions for IPV perpetrators informed by this research will be more effective in reducing their abusive behaviour. This will improve their quality of life in terms of healthy relationships, avoidance of sanctions and the negative consequences associated with criminal justice system involvement (e.g. a criminal record).

Description The aims of the research project were to examine the development of intimate partner violence (IPV) perpetration, to investigate this development of IPV perpetration in relation to the development of general criminal behaviour, and to identify 'desistance' factors for IPV perpetration, using different longitudinal quantitative datasets from the Netherlands and the United States.

Key research findings:

1. Development of IPV perpetration: IPV perpetration is relatively common during young adulthood. It mainly concerns psychological and minor physical IPV, whereas severe physical IPV is less common. Prevalence and frequency of IPV perpetration decrease throughout young adulthood. However, a considerable proportion of young adults show continuity in psychological aggression, whilst a smaller group of young adults show persistence in physical IPV perpetration. The findings highlight the importance of examining the development of IPV perpetration longitudinally, to distinguish between those perpetrators who desist from or persist in IPV perpetration over time.

2. The relationship between general criminal behaviour and IPV perpetration: The research project demonstrated a robust relationship between patterns in general criminal behaviour and IPV perpetration. The findings indicate that those who show higher levels of general offending and/or more diverse offending patterns are more likely to engage in (psychological and physical) IPV perpetration, to use severe physical violence, to use their violence more frequently, and to persist in IPV perpetration over time. Therefore, it is useful to view IPV perpetration as part of a broader criminal career, and to use longitudinal methods and a life course criminological approach to examine the development of IPV perpetration alongside the development of general criminal behaviour.

3. Factors associated with (changes in) IPV perpetration: Both background and current factors were found to be associated with either an increased or decreased likelihood and/or frequency of IPV perpetration. First, experiencing family violence in childhood was related to (higher levels of) psychological and physical IPV perpetration, as well as to continuity in IPV over time. General aggression and low levels of self-control were also found to be associated with an increased risk of IPV perpetration.
Second, among older men, being married was associated with an increased risk of IPV perpetration, whereas among young adults, cohabitation was related to psychological and physical IPV perpetration. Those who rate their relationship as being of a higher quality report lower rates of IPV perpetration. Furthermore, employment was associated with a lower risk of IPV perpetration among older men, whereas time spent in employment and/or education was largely unrelated to IPV perpetration among young adults.
Third, drug use was associated with an increased likelihood and frequency of physical IPV perpetration throughout young adulthood, whilst mental health problems were related to psychological IPV in young adulthood.
Thus, the research project demonstrated that both background and current factors, as well as the level of general criminal behaviour, explain (changes in) IPV perpetration. This indicates that an integrated theoretical approach is most useful to understand IPV perpetration, with the ultimate aim of informing evidence-based programmes which are crucial to prevent and reduce IPV.
Exploitation Route Academic routes: Academic researchers could replicate and expand on the findings from this research project by conducting further longitudinal research on IPV perpetration using datasets from different countries containing information on different samples of respondents, to further enhance our understanding of the development of and process of desistance from IPV perpetration.
Moreover, academic researchers could design future longitudinal studies (or future waves in existing longitudinal studies) which include measures of IPV perpetration to facilitate the longitudinal study of IPV. It is especially important that quantitative measures of IPV perpetration accurately reflect the various forms and the dynamics of IPV.

Non-academic routes: Criminal and youth justice agencies that work with general offenders could use the findings from this research project to improve early identification of (potential) IPV perpetration among general offenders. Third sector organisations, in particular organisations working with perpetrators of IPV and/or those at risk of becoming involved in IPV, could use the findings from this research project to inform their prevention and intervention efforts.
