Johnson’s Differentiation Theory: Is It Really Empirically Supported?

Michael Johnson’s differentiation of ‘‘types’’ of domestic violence has had a significant impact on courts and providers, in part because of its claim to an empirical basis. Unfortunately, the label ‘‘situational couple violence’’ has already been used by judges and evaluators to minimize abuse claims in custody cases. Johnson’s repeated assertion that SCV is the most common form of domestic violence reinforces the marginalizing of domestic violence. But what do his data actually show? Here Professor Meier takes a close look at the research Johnson relies on and finds that it fails to prove his thesis. Rather, the data suggest that Johnson has it exactly backward: Control-based abuse is probably far more common than ‘‘situational’’ domestic violence

The Influence of Divorcing Mothers' Demeanor on Custody Evaluators' Assessment of Their Domestic Violence Allegations

A gap exists between empirical evidence demonstrating the risks posed by domestic violence (DV) and the weight that evidence is given by custody evaluators. This gap may result from common beliefs about DV that diminish or deny its seriousness, which include that mothers often make false allegations to gain advantage and that DV and high conflict are synonymous and do not require differential approaches. Using a multiple segment factorial vignette design, we systematically assessed how these beliefs influenced custody evaluators\u27 (N = 603) recommendations and judgments of the believability of allegations. Mother\u27s demeanor (i.e., hostile vs. pleasant) was the most consistent predictor of evaluators\u27 recommendations and judgments of credibility. Findings have implications for providing research-based education and training for evaluators
