Lifestyle intervention on psychotherapy and exercise and their effect on physical and psychological health in outpatients with schizophrenia spectrum disorders. A pragmatic clinical trial

Introduction Patients with Schizophrenia Spectrum Disorders (SSD) often lead unhealthy lifestyles with higher prevalence of obesity and unfavourable cardiometabolic parameters with less life expectancy and often worse quality of life compared with general population. Objectives Evaluate the effectiveness of a combined intervention of exercise and psychoeducation in 48 SSD outpatients with metabolic syndrome (MetS), treated with second-generation antipsychotics and also aimed to explore if the effect persisted in a long-term follow-up of 24 months. Methods The intervention included a 12-week aerobic exercise program and a session of lifestyle psychoeducation. Effectiveness was measured in terms a wide range of outcomes involving physical and psychological health, functioning, quality of life, physical activity and changes in motivation to exercise in the context of the self-determination theory. Results The active intervention group showed benefits after Bonferroni correction over clinical global impression, identified motivation to exercise and changes of physical activity pattern. Maintenance of effects after 24 months of follow-up was observed for identified regulation to exercise and also for negative symptoms of psychosis (Table). Table.
