Epidemiology of intimate partner violence perpetration and victimisation in a representative sample.

AIMS: Intimate partner violence (IPV) is a major global public health problem. Although IPV is known to be frequent and perpetration and victimisation often co-occur, large representative samples assessing both, male and female IPV perpetration and victimisation and overlaps are missing to date. Thus, we aimed to assess victimisation and perpetration and its overlap in physical, sexual, psychological and economic IPV in a representative sample of the German population. METHODS: We conducted a cross-sectional, observational study in Germany from July to October 2021. Using different sampling steps including a random route procedure, a probability sample of the German population was generated. The final sample consisted of 2503 persons (50.2% female, mean age: 49.5 years). Participants were asked about socio-demographic information in a face-to-face interview and experience of physical, psychological, sexual and economic IPV using a questionnaire. RESULTS: A significant proportion of persons in Germany reporting IPV are both perpetrator and victim for each IPV form. The biggest overlap between perpetration and victimisation was seen for psychological IPV. Major risk factors for IPV perpetration only were male gender and adverse childhood experiences (ACEs) while major risk factors for IPV victimisation only comprised of female gender, low household income and ACEs. In the perpetration and victimisation group, gender differences were less significant; older age and lower household income did increase the likelihood of combined perpetration and victimisation. CONCLUSIONS: We have identified a significant overlap of perpetration and victimisation of IPV in the German population for men and women. However, men are at much higher risk to perpetrate IPV without being a victim. Further research and the development of adapted approaches for contexts of overlapping IPV are necessary.

Prevalence and Predictors of Affirmations of Intimate Partner Violence in Germany: A First Nationwide Study on Victimization in Women and Men.

Large-size studies on the prevalence of female intimate partner violence (IPV) victimization in Germany are rare and partly outdated; representative data on male IPV victimization are lacking altogether. The present survey addresses these gaps. For this study, the instrument of the WHO Multi-country study on women's health and domestic violence has been translated to German and adapted to be used with females and males. A random route procedure in selecting household addresses has been used to gather data on IPV in combination with an omnibus survey on (mental) health issues. A total 2,503 respondents with a minimum age of 14 years have participated (response rate=44.1%). The resulting distribution of age and gender was representative for the German population above the age of 14 years. A total of 57.6% of female participants and 50.8% of male participants have reported victimization by intimate partners during their lifespan; gender distribution differs significantly (Chi2=43.43; p<0.001). Out of the different documented subtypes, psychological IPV was most prevalent (53.6% in females, 48.0% in males). Other forms ranged between 15.2% (physical IPV) and 18.6% (sexual IPV) for females, and 5.5% (sexual IPV) and 10.8% (physical IPV) for males. All forms of victimization regularly coincided, both in females and males. Experiencing any IPV was not only significantly associated with female gender, but also with older age, periods of unemployment, poverty, and IPV perpetration. The findings highlight the still much needed global efforts to prevent IPV against women - and in general. They further support previous research in underlining that fighting poverty might also be instrumental in reducing the likelihood of IPV. The discussion further addresses the issues of reciprocity in IPV.
