Studies

Strategies to Tailor Existing Interventions for Depression During Pregnancy

The goal of this study is to develop a predictive model for antidepressant response and adherence in women experiencing depression during or in the year after pregnancy, and to bridge the implementation gap by identifying barriers and facilitators to model implementation in the health care system.

Investigator: Erickson-Ridout, Kathryn

Funder: TPMG Physician Researcher Program

Computational Strategies to Tailor Existing Interventions for First Major Depressive Episodes to Inform and Test Personalized Interventions

The goal of this study is to develop a model examining clinical, genetic, and demographic factor relations to depression course/outcomes and treatment response, using Kaiser Permanente Northern California data and the Kaiser Permanente Research Bank to develop and apply predictive computational algorithms to inform and test interventions; prepare the model for clinical implementation using a human factors framework and stakeholder input; and translate probability thresholds into treatment recommendations.
