Metacognitively oriented psychotherapy for schizotypal personality disorder: A two-case series.

Abstract

Schizotypal personality disorder represents a broad range of maladaptive behaviour, which has been linked to both personality disorder and schizophrenia spectrum disorders; however, to date, little effort has been devoted to developing psychosocial treatment approaches to address it. In response, we conducted two case studies exploring the effects of two metacognitively oriented forms of psychotherapy: metacognitive interpersonal therapy and metacognitive reflection and insight therapy for patients with schizotypal personality disorder. We chose these two forms of therapy as they have been successfully delivered, respectively, to persons with other personality disorders and schizophrenia spectrum disorders. Both treatments consisted of weekly individual psychotherapy sessions over a period of 6 months. General symptoms were assessed during the first week of treatment, at treatment end and at 1 month following treatment using the Symptom Check List-90-Revised, while schizotypal traits were assessed with the Structured Clinical Interview for DSM-5. Both patients completed all sessions, and there were no reports of any adverse outcomes. Both patients achieved reliable change in symptoms (ranging from 4.98 to 9.81) and a significant reduction in schizotypal features. Results provide preliminary evidence of the feasibility of metacognitively oriented interventions for schizotypal personality disorder. © 2019 John Wiley & Sons, Ltd.
