Assessing the Effect of Batterer Program Completion on Reassault: An Instrumental Variables Analysis
The main objective of this paper is to investigate the utility of using the instrumental variables (IV) method to estimate batterer program efficacy, i.e., the program effect among batterers who complete batterer programs. This method takes account of possible confounding due to unmeasured traits of compliers and non-compliers. A structural model is used to estimate the impact of program completion on reassault using instrumental variables (IV) regression. Data on 640 batterers enrolled at three batterer programs are used. Results obtained from IV regression are compared with those obtained from a more traditional regression analysis. The results indicate that usual regression methods yield estimates of program effect that may be biased due to confounding by unmeasured batterer characteristics. Unfortunately, IV estimates may be unreliable due to failure of some of the assumptions on which they are based. If equations are adequately identified by the non-linear functional form used to estimate them, then IV results indicate that among a very select group of batterers, program completion significantly reduces the probability of reassault. The implications of confounding due to program non-compliance, program non-enrollment and attrition for future evaluations of batterer programs are discussed. 相似文献

The majority of research on the psychosocial impact of intimate partner violence (IPV) exposure for children has focused on
IPV occurrence. The current study extended this research by examining three dimensions of IPV exposure: frequency, proximity,
and severity, and tested whether these dimensions predicted variance in adolescents’ psychosocial problems over-and-above
that accounted for by IPV occurrence. Participants included 140 adolescents and their caregivers, who were recruited for an
intervention involving maltreated youth placed in out-of-home care. After controlling for IPV occurrence, exposure to community
violence, and severity of maltreatment, results indicated a positive association between the multidimensional IPV index and
youth report of psychosocial problems. There was also a trend for a positive association between the IPV index and caregiver
report of psychosocial problems for boys. The study’s results are discussed in terms of their implications for prevention
researchers and child welfare agencies. 相似文献

Current theories of community-based collaborative governance arrangements rely on the presence (or absence) of certain antecedent community conditions as well as incentives for institutional change deriving from the sociopolitical and economic environment. The combination of antecedent conditions and incentives is helpful in understanding why collaboratives emerge and succeed in "easy" cases (strong incentives, conducive antecedent conditions). Yet the combination is of little help in understanding the institutional change puzzle for collaboratives in "tough" cases (strong incentives, poor antecedent conditions). Examination of a "tough" case in the Blackfoot watershed (Montana), which eventually blossomed into a successful collaborative, shows the importance of a particular set of new ideas, or shared norms, around which participants coalesced. These new ideas for understanding public problems, the community itself, and the relationships among stakeholders, became a broad conceptual framework for guiding stakeholder interaction as they attempted to manage the many public problems facing the watershed. 相似文献
