INTRODUCTION: Justice-involved adolescents are at high risk for sexually transmitted infections; one primary reason is co-occurring substance use. This study investigates the additive benefit of including alcohol and cannabis use content in a theory-based sexual risk reduction intervention, delivered using group-based motivational enhancement therapy.
STUDY DESIGN: This study had a cluster randomized design, with randomization of single-sex clusters to 1 of 3 interventions.
SETTING/PARTICIPANTS: Participants were male and female justice-involved adolescents (N=460) residing in youth detention facilities. Data were collected from 2010 to 2014; analyses were completed in 2018-2019.
INTERVENTION: Adolescents were randomized to 1 of 3 motivational enhancement therapy interventions: sexual risk reduction intervention, sexual risk reduction intervention with alcohol content, or sexual risk reduction intervention with alcohol and cannabis content.
MAIN OUTCOME MEASURES: The primary outcome was risky sexual behavior (aggregation of condom use and frequency of intercourse), measured every 3 months for 1 year. Secondary outcomes were theoretical mechanisms on which the intervention was based (condom use attitudes, self-efficacy, peer norms, and behavioral intentions), collected at baseline and post-test.
RESULTS: Risky sexual behavior significantly decreased from baseline to 3-month follow-up (t=10.59, p<0.001) and this decrease was maintained 1 year later (t=9.04, p<0.001). Intervention was associated with improved values on all theoretical mechanisms. Although all outcomes improved over time, changes did not differ by intervention condition (p>0.29 for all). Comparisons to a historical, information-only, sexual risk reduction control arm conducted with a similar juvenile justice sample confirm the effectiveness of all 3 motivational enhancement therapy-based interventions.
CONCLUSIONS: All 3 interventions were associated with decreased sexual risk up to 1 year later, suggesting that the intervention modality (motivational enhancement therapy) may resonate with this population beyond the specific substance use content. This single-session manualized intervention can be readily disseminated to juvenile justice settings.
