Across 38 effect sizes reflecting 37 studies and nearly 22,000 women offenders, women who participated in correctional interven...

Despite evidence that the incidence of female-to-male intimate partner violence (IPV) in the general population is as high as that of male-to-female intimate violence, until recently little attention has been devoted to understanding women perpetrators of partner violence or to the design of programs to address their violence. This study explored t...

Results of outcome evaluations of the domestic violence (DV) programs are not encouraging. Overall, the most optimistic conclusion is that these programs have only a modest impact on reducing repeat partner violence. Recently, there are calls for DV programs to "grow up," adapt a paradigm shift, shed ideology, and determine how the maximum impact c...
