Examining an Extension of Johnson's Hypothesis: Is Male Perpetrated Intimate Partner Violence More Underreported than Female Violence?
This author examined two hypotheses about under-reporting in intimate partner violence data. The first hypothesis holds that significant amounts of under-reporting of intimate partner violence occur due to stigma. The second is based on Johnson's (1995) hypothesis and proposes that missing data techniques will reveal more unreported male violence than underreported female violence. In the Project on Human Development in Chicago Neighborhoods, expectation-maximization (E.M.) and data augmentation are used to correct for item non-response. One of the unique aspects of this analysis is that it allows for the use of child outcome measures as predictors of the non-response cases of intimate partner violence. Strong evidence was found of under-reporting of both intimate partner violence and parent violence against children. Some evidence was also found to support the hypothesis that severe male violence may be more underreported than severe female violence. Modified Author Abstract.
