Brief Summary

Negative symptoms (e.g. diminished pleasure and motivation) are common in people with a diagnosis of schizophrenia. Little is known about the psychological mechanisms involved in negative symptom development and maintenance and there is limited evidence for current treatment options. Some research suggests that difficulties with metacognition; the capacity to develop and use complex ideas about oneself and others, may predict experiences of negative symptoms. This study will investigate whether Metacognitive Reflection and Insight Therapy (MERIT) improves metacognition in people experiencing negative symptoms, and if metacognitive changes lead to observable differences in behavioural manifestations of negative symptoms (e.g. low activity levels). Data will be collected via standardised assessments of metacognition and negative symptoms. Activity levels will be measured with actigraphy, which has been shown to capture differential activity patterns for individuals who experience negative symptoms compared to control groups. An assessment will also be made of whether improvements in specific aspects of metacognition (e.g. self-reflectivity) relate to changes in individual negative symptoms, such as motivation levels, and other markers of personal change, including personal and social performance, insight, and beliefs about recovery. Additionally, factors that may have impacted on the study results, such as therapist adherence to the treatment, will be reported. Eligible patients with capacity to consent will be recruited from the inpatient rehabilitation psychology services in National Health Service (NHS) Greater Glasgow and Clyde. They will be aged 18 or over, have a schizophrenia spectrum disorder diagnosis, and experience current negative symptoms. The target sample size is up to 8 patients. Participants will be measured at baseline and will receive up to 26 sessions of the MERIT treatment approach. Any therapeutic change will be observed via changes from assessments at baseline to the assessments in the initial, middle and last therapy sessions, and also metacognitive assessments at two other randomly selected time-points during therapy.
