How do you describe dichotomous thinking of Borderline Personality Disorder?
Patients with Borderline Personality Disorder (BPD) tend to perceive and evaluate every thought or situation as
black or white
good or bad
all or nothing
This dysfunctional extreme thinking can be one source of extreme actions like leaving a partnership, quitting a job or other impulsive actions. This can be the main source of extreme reactions, mood swings and interpersonal problems.
To change this dichotomous thinking a psychotherapist will point out examples of daily life to the patient and try to discuss different point of views in terms of a continuum. So the client learns a more realistic perception of his environment and personal relationships.
