Victim Impact Panels (VIPs) were introduced by Mothers Against Drunk Driving (MADD) in 1982 and have since spread throughout the United States in an attempt to reduce drunk driving. The objective of 5 VIP is to expose DUI offenders to the pain and suffering caused by drunk driving without necessarily condemning the DUI offender. The few scientific evaluations of the effectiveness of VIPs have produced mixed results. The present investigation draws on evidence from a quasi-experimental design and a five-year follow-up to probe further the effects of VIPs on DUI recidivism. Results show that 33.5% of the comparison group, but only 15.8% of the VIP group, were rearrested over the five-year period. Discrete-time event history analyses suggest that VIPs are associated with a 55.7% overall decrease in the hazard of rearrest; the VIP effect is strong in the first two years but then wanes dramatically. Methodological threats stemming from the study’s design are considered. The implications of the differing styles of VIP and the resultant outcomes are also discussed. (authors' abstract)
