Abstract
In this study we have evaluated the prognostics value of a wide range of clinical, demographic and genomic variables in the classification of depression recurrence and outcome in the Generation Scotland cohort; using a set of 14 machine learning methods. In total, 21,476 study participants under took the structured clinical interview for the Diagnostic and Statistical Manual of Mental Disorders (SCID); following data editing and quality control 475 single and 960 recurrent case episodes, and 1,130 cases and 5,043 controls were available for inclusion in the analysis. The recurrence and outcome of depression could be discriminated based on clinical and demographic
variables alone with up to 71% and 77% accuracy respectively. The inclusion of different genomic data sources did not augment the classification accuracy of depression outcome, and only increased the prognostic value for depression recurrence by 2% in two the methods applied.
