SUMMARY
A theoretical review of the Paranoid Personality Disorder (PPD) is presented along with its diagnosis criteria and treatment models used by the Cognitive-Behavioral Therapy (CBT) and the Schema Therapy (ST). The main question of PPD is distrust, based on distorted perceptions of reality. Its carriers find themselves vulnerable or defective, assigning spiteful and prevailed intentions to others. PPD shows the need for cognitive restructuring backed by techniques that enhance the reality test. On the other hand, ST highlights the correction of Early Maladaptive Schemas through experiential work. There are no studies describing the results obtained in treatment with this patient profile, but the PPD approaches are the only ones offering a specific clinical model elaborated from the work with Personality Disorders.
