This article is about "Batterer Intervention Programs" designed to reduce the odds of recidivism in men who have committed violence against their domestic partners. According to the article, BIPs have a "small but significant" effect on recidivism rates. It suggests that the effectiveness of these programs is reduced by several issues, such as the fact that 50% of participants do not complete programs and many participants have untreated mental issues and substance abuse problems. However, it has been determined that those who do complete these programs have lower recidivism rates than those who drop out. Indeed, one study found that those who complete these programs have a 46% chance of reoffending compared to 66% if they had not completed the programs.
The writers of this article have determined that a "larger, naturally occurring batterer intervention system," or BIS, should be examined as this might give a better indication of how these "community based intimate partner violence reduction projects" affect recidivism rates. Their research questions ask what predicts program completion and re-arrest, and what the effects of program completion are on re-arrest.
The results of the experiment conducted on 899 "batterers" in this article were that the odds of recidivism were reduced for those who completed the program. Those who completed had a 14.3% recidivism rate; those who did not had a 34.6% recidivism rate. These rates were higher than the re-arrest rates in other studies, such as Gondolf's multi-site study of BIPs (2002) which identified a recidivism rate of 11%.
The research found that the factors which increased the odds of redivism in batterers were younger age and use of illegal drugs. Those who completed a program could counter these increases. This research determined, in line with pre-existing research, that completing a program had a hand in preventing further violence as indicated by re-arrests. Married men and employed men were also both more likely to complete programs and less likely to reoffend in the future, as they would have more to lose by further convictions. Those with high motivation to change also were more likely to complete the BIP and BIS programs. Interestingly, it was also noted that Latino men were more likely to complete these programs, perhaps because of higher levels of community feeling among this group.
In summary, then, the research supports the concept of BIPs as an effective "extension of probation" and a measure which is proven to reduce recidivism rates and offer much-needed support to those who have been incarcerated for violent offenses.
