Findings from a randomized controlled trial of Metacognitive Reflection and Insight Therapy for people with schizophrenia: Effects on metacognition and symptoms.

Background: Research has suggested that people diagnosed with schizophrenia experience challenges in their abilities to reflect upon themselves, others and their actions in the world. One emerging approach to addressing these forms of subjective disturbance is Metacognitive Reflection and Insight Therapy (MERIT).
Aims: In this study, a randomized delayed trial was conducted to assess the effects of MERIT upon metacognition, psychiatric symptoms and quality of life.
Materials and Methods: Following recruitment and randomization, data from 54 adults diagnosed with schizophrenia were analysed.
Results: Findings included significant interaction effects between group (immediate intervention or waiting condition) and time (pre- and post intervention) with regard to the metacognition general score and its domain of mastery, as well as with regard to negative, positive and cognitive symptoms.
Discussion: Participating in MERIT seems to improve one's ability to use reflective knowledge to cope with psychological challenges and to improve, or at least maintain, level of symptomatology.
Conclusions: These findings are discussed within the framework of agency as an important aspect of recovery.
