designed to reduce drinking and offending behaviors. Some dependent variable differences between the two groups were observed at follow- up. The second study was established in Glasgow as a replication of the main study. The third study used a quasi-experimental design to establish a no- intervention control group in the Perth courts. Young offenders were recruited to complete screening interviews, without any intervention. The intervention group was re­ cruited from courts in Forfar, a similar rural town. This group completed an infonoation-based ABC, using educational materials about alcohol and its effects. Some dependent variable differences were observed at follow- up. The fourth study was based in a Young Offender Institution at Forfar. Prerelease young offenders were randomly assigned to either a no-intervention control group or a behavioral ABC group. Some dependent variable differences were reported at follow-up.
