Metacognitive reflection and insight therapy for schizophrenia: Case study of a patient with a co-occurring substance use disorder

Abstract

Decrements in metacognitive functioning, or the ability to form complex and integrated representations of oneself and others, have been identified as a core feature of schizophrenia. These deficits have been observed to be largely independent of the severity of psychopathology and neurocognitive functioning and are linked to poor outcomes for those with the disorder. This study is a case illustration of the efficacy of metacognitive reflection and insight therapy (MERIT) in increasing the metacognitive capacity of an individual diagnosed as having co-occurring schizophrenia and a substance use disorder during three years of individual therapy. The eight elements of MERIT, which promote metacognitive growth, are presented as they apply to the present case. Case conceptualization, outcomes, and prognosis are also presented. These eight elements enabled the patient to move from a state of gross disorganization-unable to identify his thoughts or present them in a linear fashion-to one in which he was able to develop increasingly complex ideas about himself and others and integrate this understanding into a richer sense of himself, of his psychological challenges, and of the role that substance use played in his life. Results of the study also illustrate the foundational necessity of self-reflectivity in order to facilitate understanding of the mind of others and the relationship between psychological pain and the emergence of disorganization.
