A Two-Week Psychosocial Intervention Reduces Future Aggression and Incarceration in Clinically Aggressive Juvenile Offenders

Abstract

<div class="section"> <a class="named-anchor" id="S1"> <!-- named anchor --> </a> <h5 class="section-title" id="d3962960e150">Objective</h5> <p id="P2">There is a largely unmet need for evidence-based interventions that reduce future aggression and incarceration in clinically aggressive juvenile offenders serving probation. We addressed this gap using a group randomized controlled trial. Offenders both with and without clinical aggression were included, enabling comparison of intervention effects. </p> </div><div class="section"> <a class="named-anchor" id="S2"> <!-- named anchor --> </a> <h5 class="section-title" id="d3962960e155">Method</h5> <p id="P3">Juveniles 13–17 years old ( <i>N</i> = 310, mean = 16 years, 90% African-American, 66% male) on probation were assigned to a 2-week intervention targeting psychosocial factors implicated in risky behavior (e.g., learning strategies to manage “hot” emotions that prompt risk taking) or to an equally intensive health promotion control. Participants completed aggression measures at baseline, 6-, and 12-month follow-up and reported on incarceration at 12 months. Spline regression tested symptom change. </p> </div><div class="section"> <a class="named-anchor" id="S3"> <!-- named anchor --> </a> <h5 class="section-title" id="d3962960e163">Results</h5> <p id="P4">Among clinically aggressive offenders ( <i>n</i> = 71), the intervention arm showed significantly greater reductions in aggression over the first 6 months compared with controls. Juveniles from the intervention no longer met clinical criteria, on average, but clinically significant symptoms persisted in the control group. By 12 months, participants from the intervention appeared to maintain treatment gains, but their symptom levels no longer differed significantly from those in the control. However, the intervention group was nearly 4 times less likely than controls to report incarceration. Intervention effects were significantly stronger for offenders with clinical than nonclinical ( <i>n</i> = 239) baseline aggression. </p> </div><div class="section"> <a class="named-anchor" id="S4"> <!-- named anchor --> </a> <h5 class="section-title" id="d3962960e174">Conclusion</h5> <p id="P5">A 2-week intervention expedited improvements in aggression and reduced incarceration in clinically aggressive juvenile offenders. The findings underscore the importance of directing intervention resources to the most aggressive youth. </p> </div><div class="section"> <a class="named-anchor" id="S5"> <!-- named anchor --> </a> <h5 class="section-title" id="d3962960e179">Clinical trial registration information</h5> <p id="P6">PHAT Life: Preventing HIV/AIDS Among Teens in Juvenile Justice (PHAT Life); <a data-untrusted="" href="http://clinicaltrials.gov/" id="d3962960e183" target="xrefwindow">http://clinicaltrials.gov/</a>; NCT02647710. </p> </div>
