The purpose of this study was to investigate whether or not specific differences existed between
Driving While Intoxicated (DWI) offenders mandated to attend VIPs and offenders who were not
mandated. The authors used a local substance-dependency screening program to determine the
severity of drug and alcohol dependency or abuse in first-time and repeat DWI offenders convicted
in Bernalillo County, NM. The final sample consisted of 5,238 first-time and 1,464 repeat convicted
offenders referred for drug and alcohol screening by the court. The authors found that 20 percent
of first-time offenders were repeat offenders who had been mislabeled owing to faulty data.
Logistic regression analysis found that participation in a VIP was not associated with reduced
recidivism risk, but that certain factors were highly predictive of re-offense: male gender, Native
American race or Hispanic ethnicity, unmarried status, fewer than 12 years of education, previous
substance dependency treatment, a DWI arrest resulting from a crash, a BAC of .20 or higher at
time of arrest, and a refusal to submit to a blood or breath test. The authors also found that female
judges were significantly more likely to assign offenders to VIP participation, though no explanation
for this finding emerged from the data.

This was a follow-up study of the same VIP and comparison groups selected in C’De Baca et al
(2000). This study investigated recidivism among drivers convicted of DWI in New Mexico, two-
thirds of whom attended VIPs. Earlier research identified several covariates predicting DWI
recidivism, including age, marital status, educational attainment, prior driving record and treatment
history, BAC at time of arrest, ethnicity, and whether DWI arrest coincided with a vehicle crash.
Thus, where possible those variables were also obtained for each subject. Gender is a well-known
covariate, so male and female offenders were analyzed separately, for both first-time and repeat
offenders. The follow-up period lasted between two and a half to eight years to ensure more
complete results. Data analysis showed no significant difference in DWI recidivism between first-
offender males or females sentenced to VIPs versus those who did not attend VIPs. The same
finding held true for repeat-offender males sentenced to VIPs and their matching controls.
However, female repeat-offenders who attended VIPs were more than twice as likely to recidivate
as female repeat-offenders who did not attend. To explain this counter-intuitive finding, the
authors cited research showing that a repetitive focus on painful current-life situations can
engender “a sense of distress, helplessness, and hopelessness, leading to increased drinking and
recidivism” (619).
