Motivational counseling reduces future police charges in court referred youth.

By the age of 18, between 16 and 27% of adolescents in the U.S. have been arrested for an offense and by the age of 23 this increases to a staggering 25-41%. Most youth that get into legal trouble have a substance abuse problem and many youth report high risk driving behaviors. Adjudication of adolescents for an offense may provide an opportunity to provide a secondary prevention program for such high risk behaviors. In this regard the primary aim of the present study was to test two hypotheses: (1) that interventions involving group motivational interviewing would decrease future legal charges beyond those achieved by the combination of sanctions and remedial actions otherwise mandated by the court; and (2) that the addition of a trauma room exposure to the group MI intervention would increase the effectiveness of MI in decreasing these future legal charges. Court mandated youth who have had a high risk driving police charge and/or alcohol related police charge and who are drivers (n=992) were randomly assigned to one of the three 20h interventions; enhanced prototypic community service (CS), Motivational Intervention with typical community service (MI), and Motivational Intervention with exposure to a hospital trauma center (MI-H). As hypothesized, the probability of being charged with an offense within the 6 months post-treatment was significantly less for participants in the combined MI groups than those in the CS group. The combined MI groups also had significantly fewer overall number of police charge events than the CS group at 6 months. Mediation analyses revealed that the relationship between MI vs. CS interventions and subsequent police charges was partially accounted for by the youth's experience of the MI component of the intervention. Despite fewer police charges at 6 months the combined MI group reported (1) significantly more hazardous drinking and (2) a greater amount of speeding and distracted driving than the control group over this same 6-month period. Hypothesis 2, that MI-H would be more effective than MI in reducing police charges, was not supported. This was so despite evidence supporting the hypotheses that (1) trauma room exposure would increase participants' emotional arousal during the intervention and (2) increased arousal would be predictive of fewer police charges. Despite support for the theorized causal pathway, the combination of trauma room exposure and MI did not result in better outcomes than MI combined with traditional community service. Given this discrepancy between empirical supports for the theory in the face of the absence of incremental effectiveness of the MI-H treatment condition, a better understanding of the participant's hospital experience will be necessary if we are to successfully utilize the trauma room exposure to increase the effectiveness of MI interventions for this target group to achieve better outcomes.
