There are four modules of Dialectical Behavioral Therapy (DBT): mindfulness, interpersonal effectiveness, distress tolerance, and emotional regulation. Clients are taught to recognize different states of mind. A pilot study found that participating in a 12-week DBT inpatient program, including group and individual sessions, significantly reduced activity in the caudal anterior cingulate cortex, improving regulation of affective arousal in patients with borderline personality disorder. Practicing mindfulness can help manage stress and its physiological effects by improving mood control, motivation, and interpersonal relationships.
