She believes that a combination of medication (Abilify) and psychotherapy (Dialectical Behavior Therapy; DBT) will be more effective than medication or therapy alone in reducing impulsive behavior in patients with borderline personality disorder. To test this, she performs only DBT on 5 of her patients with borderline personality disorder, she treats 5 of her patients with Abilify, and she uses a combination of both on another 5 of her patients. Participants are randomly assigned to treatment conditions. After two months of treatment, she administers the Barratt Impulsivity Scale (BIS; scores range from 30 to 120) where higher scores indicate more impulsivity. Below are her results.
