Metacognition over time is related to neurocognition, social cognition, and intrapsychic foundations in psychosis

Core impairments underlying schizophrenia encompass several domains, including disruptions in metacognition, neurocognition, social cognition, and intrapsychic foundations. Little is known about how these phenomena change over time and whether changes co-occur. The current study sought to address these gaps and examine the relationships between these cognitive domains across a 12 month period in adults with schizophrenia. Seventy-five adult outpatients with schizophrenia spectrum disorders were enrolled in a randomized trial comparing two cognitive interventions designed to improve work performance. Cognitive outcomes were measured at baseline, a 6-month follow-up and a 12-month follow-up. Multilevel linear modeling was used to understand the longitudinal relationships between metacognition and social cognition, neurocognition, and intrapsychic foundations across the 12-month follow-up. Metacognition significantly improved across 12 months. Improvements in overall neurocognition were significantly associated with increases in the metacognition domains of self-reflectivity and mastery across time. Improvements in social cognition over time were associated with improvements in total metacognition and the metacognitive domain of mastery. Improvements in intrapsychic foundations scores over 12 months were significantly associated with improvements in overall metacognition, self-reflectivity, and mastery. In conclusion, over time, improvements in metacognition across domains co-occur with other core cognitive and social capacities in persons with schizophrenia. As persons became better able to form integrated senses of themselves and adaptively use this knowledge, improvements in neurocognition, social cognition, and intrapsychic foundations were also present.
