Anti-social personality disorder is a complex treatment problem. Usually, the treatment that uses psychotherapy takes a long time. Psychologists will recommend different types of psychotherapy based on the person's situation.

Cognitive behavioral therapy can help reveal negative thoughts and behaviors. It can also teach how to replace them with more positive thoughts and behaviors.

Psychodynamic or distraction therapy can increase awareness of consciousness, symptomatic meanings, and unconsciousness. This can help the person change them.
