Schema-Focused (SF) Therapy is an extension of cognitive therapy that was developed to address the treatment needs of patients with long-standing mental disorders. SF therapy focuses on early maladaptive schemas (EMS): broad, pervasive themes regarding oneself and one's relationship with others, developed during childhood and elaborated throughout one's lifetime, which are dysfunctional to a significant degree. SF Therapy involves the identification of the particular EMS that is most relevant for each patient and attempts to modify the relevant schemas by altering the distorted views of self and others.
