Plain English Summary

Background and study aims
Dialectical behavior therapy (DBT) is a psychological treatment that is known to work well for women with borderline personality disorder (BPD). It has been developed from cognitive behavior therapy (CBT) but modified to meet the needs of people with BPD. CBT focuses on helping people change unhelpful ways of thinking and behaving. DBT does this too, but it also encourages people to accept who they are and includes elements of mindfulness, a mind-body approach developed to help people change how they think about experiences and how to reduce feelings of stress and anxiety. However, to date, there has been a lack of DBT-treatment studies looking at how it may help men with BPD being treated in outpatient clinics. Here, we will look at how well DBT performs when treating men with BPD with a history of anti-social behavior. We want to know to what extent 12 months of DBT might reduce suicidal, impulsive and antisocial behaviors, how much it improves psychological well-being and whether it is considered useful by the participants involved. We also want to investigate variables that might influence the effect of the treatment.

Who can participate?
Men with a diagnosis of borderline personality disorder and antisocial behaviors within Stockholm Psychiatry

What does the study involve?
After the diagnosis of BPD has been made, participants are asked to self-record their antisocial and impulsive behaviors for 4 weeks before the treatment starts. They also attend an interview where they recall their antisocial behavior. They then start a 12 month course of DBT therapy, where they learn how to manage their emotional reactions and destructive behaviors. Participants are asked to self-record their antisocial/impulsive behaviors and attend further interviews 6 months after the treatment starts and at the end of treatment.

What are the possible benefits and risks of participating?
All participants receive intensive DBT treatment, which is known to be helpful for women with BPD. Based on earlier studies, we expect the treatment to help most participants reduce their self-harming, impulsive and anti-social behaviors.

Where is the study run from?
The treatment will be conducted at two psychiatric outpatient clinics in Stockholm.

When is the study starting and how long is it expected to run?
December 2013 to December 2016

Who is funding the study?
Swedish Prison and Probation Service (Sweden)
