I write to correct some of the misrepresentations of fact in Bob McCoskrie's opinion piece that appeared in the Herald this week.
The claim that one in three women have been victims of intimate partner violence in their lifetime is correct. The statistic is based on findings from the New Zealand Violence Against Women Study, published in the New Zealand Medical Journal in 2004. The largest of its kind ever undertaken in New Zealand, the study used state-of-the-art methods in collecting information on prevalence of violence, based on a questionnaire developed and used extensively by the World Health Organisation.
We collected data from almost 3000 New Zealand women. Yes, they lived in Auckland and the Waikato, but comparison of the characteristics of our sample (e.g. age, ethnicity, marital status) with women in the nation as a whole makes it clear that our findings can be generalised to women in NZ. The one-in-three statistic refers to women's experience of physical and/ or sexual violence by an intimate partner in their lifetime. Physical violence includes such things as being slapped, kicked, hit with a fist, burned, choked or threatened with a weapon.
Yes, the entry criteria was "did this happen to you one or more times in your life", but we also have data on frequency. Over 80 per cent of women who experienced physical violence, and over 90 per cent of those who experienced sexual violence were hurt on more than one occasion, in multiple ways, or both.
The statistics are actually worse if you include prevalence of emotional violence. Data from the same study indicate that in their lifetime just over half of New Zealand women report that their partners have: insulted them or made them feel bad about themselves; belittled or humiliated in them front of other people; or scared or intimidated them on purpose. Physical and sexual violence almost always co-occurred with emotional violence. These high lifetime rates of physical, sexual and emotional violence are of concern because of the long-term health and social consequences created by trauma.
