Multicentre RCT comparing two interventions targeting externalizing behavior in patients enrolled in opioid agonist treatment (OAT)
Externalising behavior
A parallel group, two arm, superiority trial comparing ILC with MOVE individual treatment for opioid use disorder (OUD). Participants will be recruited at four Danish treatment centers in four large Danish cities and municipalities, where the treatment will take place. In all, 137 individuals who seek/are undergoing treatment for opioid use disorders will be offered participation in the study. At each treatment center, participants will be randomized to one of two conditions: ILC/MOVE or MOVE. Recruitment will continue for one year. An extensive baseline assessment will be made approximately one week after randomization (interview by clinician), and follow-up assessments will be conducted at 3 and 9 months post-randomization. The most important outcome measures are: retention; substance use; every day functioning; illegal activities, social interaction with individuals (family, friends, acquaintances) with non-criminal behavior and/or with no substance abuse; employment/educational activities. The two interventions that are tested in the trial: 1. The Impulsive Lifestyle program (ILC): Eight sessions targeting externalizing and criminal behavior. The ILC aims to support change in lifestyle, and involves a psychoeducational and motivational approach. The eight sessions will be followed by six MOVE (i) sessions. 2. MOVE: 14 MOVE sessions (a combination of motivational interviewing, cognitive behavioral therapy, and contingency management). All participants will receive vouchers (200 DKK) at every second session attended, and at participation in follow-up interviews. Case control: The case-control group will be drawn from The Registry of Drug Abusers Undergoing Treatment (SIB). The trial conditions will be compared using SIB; the Danish National Patient Register (Landspatienregistret); The Danish Registry for Causes of Death (Dødsårsagsregistret); The Psychiatric Central Research Register (Det Psykiatriske Centralregister); The Danish Central Crime Register (Det C
