Background

In order to gain understanding of changes over time and across genders with regard to intimate partner homicide (IPH), more research is warranted. International research, mainly from the U.S., demonstrates a radical decrease in female-perpetrated IPH over time, while the decrease in male-perpetrated IPH has been modest.

Objectives

The overall objective is to examine trends of IPH across time, in which homicides committed between 1990 and 2013 in Sweden, will be investigated. Perpetration rates of male- and female-perpetrated IPH will be compared, furthermore, the gender-specific rates of IPH will be compared to rates of male- and female-perpetrated homicides that are not partner related.

Method

The retrospective study is based on a dataset collected by the Swedish National Council for Crime Prevention, which comprises data on all homicide cases in Sweden from January 1st, 1990, to December 31st, 2013. Rates of gender-specific IPH and non-IPH will be analysed and presented using the Poisson Regression and Incidence Rate Ratio (IRR). Predictive factors of male- and female-perpetrated IPH will be analysed by using multiple logistic regressions, in which socio-demographic, criminological and crime scene factors will be considered.

Hypotheses

Homicide rates overall are hypothesized to have decreased, however, IPH rates are hypothesized to display more modest reduction in comparison to non-IPH.

Implications

Current research on gender-specific characteristics and trends related to IPH is limited. In the long run, research of such may have critical implications for policy initiatives and community safety planning.

Biography

Shilan Caman is a PhD-candidate at Karolinska Institutet in Stockholm, Sweden, and currently a visiting PhD-candidate at Griffith University. Her research interests broadly include various forms of violence, especially partner violence. Her thesis treats intimate partner homicides, in which offender; victim and incident correlates are compared to correlates of homicide cases that are not partner related. She is currently investigating intimate partner homicides across time and gender, in which incidence rates and characteristics of all homicides committed in Sweden between 1990 and 2013 are examined.
