This article summarizes a systematic review of published and unpublished evaluations of DWI Court programs released through April 2007. The review found that one evaluation exceeded 80% of recommended scientific criteria and was deemed "good", while four others exceeded 65% of criteria and were deemed "marginally acceptable". However, many evaluations had serious shortcomings like only reporting outcomes for graduates or failing to account for participant dropout. Overall, the state of the evaluation literature does not allow for scientifically defensible conclusions about the effects of DWI Courts due to inadequate methodological quality. The authors hope the criteria outlined can help improve future evaluations.
