Paranoid personality disorder (PPD) is a challenging mental illness to treat, as there are not a variety of options for treatment that are empirically supported. Cheli et al. (2021) conducted a case study, in which a 61 year old man presented with severe symptoms of PPD. The patient was treated with Metacognitive Interpersonal Therapy (MIT).
In MIT, the therapist will help the patient change their views on challenging situations that they encounter. The therapist helps the client become aware of their maladaptive schemas, which guide the client’s negative behavior.
After 6 months of MIT, the client “reported a reliable change in general symptomatology and, specifically, in interpersonal sensitivity, hostility, and paranoid ideation; he could no longer be diagnosed as PPD” (Cheli et al., 2021).
This study suggests that intervention is possible for PPD, and that patients with this condition can engage in therapy to lessen their symptoms.
