Adolescence is a vulnerable period for developing Major Depressive Disorder (MDD) and represents an opportune time to identify early risk factors for this debilitating illness. Although previous studies have documented multiple risk factors for the development of MDD—including demographic, clinical, psychosocial, and neurobiological predictors—research in this area has mostly focused on a relatively limited set of risk markers rather than optimizing prediction across a broad set of factors. Phenotyping at this scale is resource intensive and often requires multi-site initiatives to sufficiently sample an expansive parameter space. Using data-driven statistical methods, researchers can then identify top features in a predictive model and effectively constrain this parameter space, which has enormous potential to guide future depression studies with more limited sample sizes.In this issue of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, a study by Toenders et al.(1) makes significant strides in identifying multi-level risk factors for adolescentonset depression by leveraging data from the IMAGEN consortium, an eight-site European collaborative where over 2,000 adolescents at age 14 were assessed and followed through ages 16, 19, and 22. In their investigation, the authors included 145 baseline variables—including clinical, cognitive, and environmental factors, as well as measures of gray matter morphometry from 34 cortical and 8 subcortical regions—in a penalized logistic regression to identify depression (defined as meeting subthreshold or full-threshold MDD from a well-validated selfreport measure of depression symptoms) by age 19. The authors found that baseline depression severity at age 14, female sex, neuroticism, stressful life events, and surface area of the supramarginal gyrus were the strongest contributors to a model that predicted onset of depression (AUROC values: 0.68–0.72). Critically, the authors used different levels of penalization and evaluated their model performance on an independent set of data (n= 137) that were not used to train their model (n= 407). Interestingly, the same model was also predictive of the onset of risky alcohol use in an independent subsample from the data, which highlights that these features are likely to be predictive more generally of mental health outcomes during adolescence.
