Brain mechanisms of rumination and negative self-referential processing in adolescent depression.

Background: Depression is linked to cognitive biases towards more negative and less positive self-relevant information. Rumination, perseverative negative thinking about the past and the self, may contribute to these biases.

Methods: 159 adolescents (12-18 years), with a range of depression symptoms, completed the SRET during fMRI.

Predicting states of elevated negative affect in adolescents from smartphone sensors: a novel personalized machine learning approach.

Background: Adolescence is characterized by profound change, including increases in negative emotions. Approximately 84% of American adolescents own a smartphone, which can continuously and unobtrusively track variables potentially predictive of heightened negative emotions (e.g.

Multi-modal assessment of reward functioning in adolescent anhedonia.

Background: Anhedonia is a core symptom of depression that predicts worse treatment outcomes. Dysfunction in neural reward circuits is thought to contribute to anhedonia. However, whether laboratory-based assessments of anhedonia and reward-related neural function translate to adolescents' subjective affective experiences in real-world contexts remains unclear.
