Clinical Trial Summary
This study will determine whether dialectical behavior therapy and fluoxetine are more
effective combined or alone in treating people with borderline personality disorder.
Description:
Borderline personality disorder (BPD) can be a serious and very complex condition. BPD
affects 2% to 3% of the population and is more commonly diagnosed in young women. BPD is
characterized by mood swings, impulsive behavior, difficulty controlling emotions, and acting
out inappropriately either through self-harm or attempts of suicide. Other illnesses such as
depression and anxiety are also very common in people diagnosed with BPD. Various treatments
exist that aim to reduce self-harm and suicide among people with BPD. Dialectical behavior
therapy (DBT), an outpatient behavioral therapy shown to help self-injurious patients with
BPD, has become a popular treatment. Another useful treatment, the antidepressant fluoxetine,
can help to regulate mood and diminish suicidal or self-destructive urges. Although
combination treatments of DBT and fluoxetine are common, little research has been conducted
on the effectiveness of this kind of combined treatment. The purpose of this study is to
determine whether DBT and fluoxetine are more effective combined or alone in treating people
with BPD.
All participants in this double-blind study will receive a psychiatric and medication
evaluation prior to starting treatment. Participants taking psychiatric medications prior to
the study will be slowly withdrawn from the medications over a period of 2 to 6 weeks.
Psychological interviews and self-report questionnaires will be administered, taking
approximately 5 to 10 hours to complete. Once all preliminary interviews and evaluations have
been completed, each participant will be randomly assigned to one of the four following
treatment groups:
- Group 1 will receive DBT and fluoxetine (Prozac). DBT teaches patients new skills to
replace old coping strategies such as suicide attempts and self-injury. Participants
will work with an individual therapist for 1 hour a week to learn these new skills. This
group will also be expected to keep a weekly diary that will discuss their current mood;
suicidal and self-harming urges; and possible use of medications, drugs, and alcohol.
Once a week participants will engage in a 90-minute skills training group to review the
skills learned during therapy. Homework will be assigned between sessions to review
these new strategies and skills. Participants will meet regularly with a psychiatrist to
receive fluoxetine, discuss any side effects, and adjust dosage if necessary.
- Group 2 participants will receive DBT and placebo medication.
- Group 3 participants will receive supportive therapy and fluoxetine. Supportive therapy
is nondirective and focuses on strengths, coping abilities, and current areas of
difficulty in life in an unstructured format. Participants in this group will meet with
an individual therapist each week for 50 minutes. Patients will also be assigned to a
psychiatrist to receive fluoxetine every other week.
- Group 4 participants will receive supportive psychotherapy and placebo medication.
All patients participating in this study will continue treatment for 12 months and will be
evaluated bimonthly. After 12 months, participants will undergo neuropsychological testing to
identify any changes that occurred over the last year. The clinical status of each
participant will also be assessed at 18 and 24 months.
