Drivers Under the Influence Intensive Supervision Program

An Evidence-Based Practice

Description

The Drivers Under the Influence (DUI) Intensive Supervision Program (DISP) is a court-based intervention for repeat impaired-driving offenders. DISP is an incentive-based plea program that allows eligible participants to enroll in the program rather than face traditional sanctions. After choosing to join, participants come under the Court's supervision and are required to serve some or all of their confinement time, participate in alcohol and drug monitoring, undergo random alcohol and drug testing, refrain from driving, and make regular court appearances. Participants are electronically monitored and must attend mandated treatment sessions, weekly Alcoholics Anonymous meetings, a victim impact panel discussion, and monthly meetings with a probation officer. Those that meet the requirements of each phase of the DISP plan graduate from the program and the sentence against them is either amended or deferred. Those that are noncompliant with the program requirements are served additional jail time.

Goal / Mission

The goal of the DISP program is to reduce drunk driving among alcohol traffic offenders.

Results / Accomplishments

This program was evaluated using a randomized controlled trial to compare recidivism among DISP participants and a comparison group. The relative risk for DISP participants of re-arrest for DUI was 0.52 (95% CI = 0.36-0.76) when compared to the control group, after adjusting for gender, age, and number of DUI convictions. Relative risk for driving while revoked or suspended was 0.46 (95% CI = 0.34-0.63), and risk for all other convictions was 0.61 (95% CI = 0.48-0.77). Number of prior arrests had no statistically significant impact on traffic outcomes.

An Evidence-Based Practice meets the following HCI criteria:

  1. The program description includes at a minimum: the sponsoring organization, program goals, program implementation steps, and outcomes that have demonstrated program success in achieving the program goal in one or more localities.
  2. The results from an evaluation of the program include quantitative measures showing improvement in the outcome(s) of interest after the implementation of the program (i.e. increase in smoking cessation, not just the delivery of a smoking cessation program). The outcome measure(s) is/are compared at relevant time periods before and after the intervention or program implementation. Alternatively, the evaluation study compares the outcome(s) between an intervention group and an appropriate control group.
  3. The study is of peer-review quality and presents numbers in a scientific manner; measurements of precision and reliability are included (e.g. confidence intervals, standard errors), results from statistical tests show a significant difference or change in the outcome measure(s), and relevant point estimates and p-values are presented. Note: if the results from an evaluation of a program are presented in a scientific manner and the outcome measure is improved compared to the baseline measurement or the control group but the difference is not statistically significant, the practice is classified as effective and not evidence-based.
