title: DUI offenders' experience with an ignition interlock program: comparing those who have and have not adapted from their primary drinking location.
abstract: OBJECTIVE
  The purpose of this study was to compare driving under the influence (DUI) offenders on an alcohol ignition interlock program who had or had not changed their primary drinking context from a bar/restaurant where they might be required to drive after drinking before the interlock was installed to drinking at home where driving would not be likely to be required following interlock installation.
  
  
  METHODS
  A total of 171 DUI offenders who were on an ignition interlock program completed a web-based survey. All of these offenders reported that they drank primarily in a bar/restaurant before the interlock was installed. These offenders were classified into 2 groups: adapters who said they currently drink at home and nonadapters who said they still drink in a bar/restaurant. Measures were made of their reported drinking, driving patterns, perceptions of the likely outcomes of being on the interlock, perceived effectiveness of various prevention strategies, and demographic characteristics. Chi-square and t-test analyses were used to compare these 2 groups.
  
  
  RESULTS
  Adapters and nonadapters did not differ with regard to any of the demographic characteristics, whether they were a first-time DUI offender, the length of time in the interlock program, number of lockouts (being blocked from starting their cars) they had experienced, miles driven per week, or current driving patterns since being on the interlock program. Adapters were more likely to report changing their drinking plans and habits. Currently they reported fewer drinks per occasion than nonadapters. They were more likely to report reducing the amount they drink, solo drinking or only drinking with a spouse/significant other, and changing their drinking plans and habits. They were also more likely to say that the interlock reminded them to limit their drinking after it is removed and that it might have longer term benefits in preventing future DUIs. They were also more receptive to interventions that might help them separate their drinking from their driving.
  
  
  CONCLUSIONS
  Interlock clients who report that they have altered their drinking context and a willingness to receive programs that help them separate their drinking from their driving may be more receptive to and benefit from ignition interlock programs.
