Young offenders show high levels of substance use. Treatment programs within detention settings are less effective. Cognitive bias modification (CBM) is a promising supplement to substance use treatment. This study tests the effectiveness of CBM in young offenders to reduce cannabis and alcohol use, and delinquent recidivism. A randomized controlled trial added CBM to treatment as usual (TAU), among 181 youth in juvenile detention centers. In a factorial design, participants were randomly assigned to either active- or sham-training for two varieties of CBM, targeting attentional-bias (AtB) and approach-bias (ApB) for their most used substance. Substance use was measured with the Alcohol and Cannabis Use Disorder Identification Tests. Delinquent recidivism was measured with the International Self-Report Delinquency (ISRD) survey. At pretest, participants showed AtB but no ApB for both substances. For alcohol, a decrease was found in AtB in the active-training group. For cannabis, a decrease was found in AtB for both active- and sham-training groups. Regardless of condition, no effects were found on substance use or ISRD scores at follow-up. The sample is judicial, not clinical, as is the setting. TAU and participant goals are not necessarily substance related. Young offenders show a significant attentional-bias towards substance cues. CBM changed attentional-biases but not substance use. Combining CBM with a motivational intervention is advised. Follow-up research should better integrate CBM with running treatment programs. New developments regarding CBM task design could be used that link training better to treatment. • First implementation of Cognitive Bias Modification with detained juveniles. • Attentional biases found for alcohol and cannabis stimuli. • CBM training tasks successfully reduce attentional biases. • Substance use at follow-up is not significantly lower compared to sham-training.
