Abstract
The report is the first interim analysis concerning the effectiveness of the CDUI Project's education programs for first offender DUI's. Treatment effectiveness was assessed in terms of recorded accidents, DUI offenses, and total moving violations occurring subsequent to random assignment. Survival analysis was used to compare control, home study, and in-class education groups. Comparisons were made for the total research sample (all assigned as of October, 1979), for two age subgroups, and three diagnostic subgroups (drinking problem severity). A comparison was also made between the research sample and a sample of non-volunteers to assess ability to generalize results.
