Plain English Summary

Background and study aims
Some people who abuse alcohol or other drugs also have persistent problems with impulsive behaviour, crime and aggression. This is called an antisocial personality disorder. There is currently no specialized help for people with these problems in outpatient substance abuse treatment services.

Who can participate?
Men and women, aged over 17, who have attended substance abuse treatment services in Denmark.

What does the study involve?
The study involves a brief interview and the completion of a questionnaire. After this, half the participants receive the best standard of care at their local substance abuse treatment unit. The other half receive the same care plus six sessions of counselling and information about impulsive and aggressive behaviour. The treatment to which a participant is allocated to is decided by a process called ‘randomisation’, which is like a coin toss. Three months after this, all participants are invited to an interview about their current situation and the treatment they have received.

What are the possible benefits and risks of participating?
There are no immediate benefits to participating. If the counselling program turns out to be helpful, participation may help future patients receive a better standard of care. The same standard of care applies to all patients whether or not they choose to participate, and they can withdraw from the study at any time.

Where is the study run from?
University of Aarhus (Denmark).

When is the study starting and how long is it expected to run for?
March 2012 to July 2013

Who is funding the study?
1. Reckitt Benckiser (Denmark)
2. University of Aarhus (Denmark)

Who is the main contact?

Antisocial personality disorder


Treatment as usual (TAU):
All participants in the control group receive treatment as usual, i.e. whatever treatment they would have received if the trial had not been taking place. Treatment as usual include casework, whatever counseling models each of the participating clinics provide, opioid substitution treatment, referral to psychiatric treatment as needed.

Experimental treatment:
Patients in the experimental condition receive treatment as usual, and are additionally offered a 6-session therapy based on the Lifestyle Issues program developed by Glenn D. Walters. In line with the Criminal Lifestyle Theory, the ILC program is presented as an approach to change the client’s life.
All six sessions take one hour. The first 5 sessions focus on separate issues: session 1 focuses on educating the client about the treatment approach, increasing awareness of problems associated with an impulsive lifestyle, and identifying client goals. Session 2 uses a problem-solving approach to identify concrete difficult situations that the client encounters in daily life. Session 3 focuses on “streetwise pride” and client experiences of self-esteem based on streetwise pride. Session 4 addresses pro-social and antisocial values, session 5 focuses on social networks and their push or pull effect regarding change of lifestyle, and session 6 is a booster session which takes place 6 weeks after session 5. Here the client is invited to discuss the issues that have come up in previous sessions. All sessions are described in a detailed manual with pre-printed handouts and pre-printed homework assignments.
