Longitudinal Assessment of Biomarkers Among Patients With MDD
This prospective observational study will evaluate whether speech collected through a smartphone application can be used to assess depressive symptom severity and detect symptom changes among adults with major depressive disorder receiving ketamine, esketamine, or infliximab.
Up to 100 participants will complete brief speech tasks and self-report measures of depression, anxiety, and insomnia at baseline, week 2, and week 4. Clinician-rated depression severity will be assessed at baseline and week 4.
Optional passive smartphone data, including activity and sleep measures, may also be collected. The study will examine the agreement between speech-based model predictions and established clinical assessments, as well as the ability of the model to identify symptom severity and treatment response. The study is observational and will not alter participants' clinical treatment. By evaluating remote speech-based assessments alongside optional passive behavioral monitoring, this research may support more effective measurement-based care and improve the evaluation and management of depression in clinical settings.

Gedetailleerde beschrijving
In this observational study, adults with Major Depressive Disorder (MDD) receiving ketamine, esketamine, or infliximab will be followed for up to 4 weeks. Data collection will include smartphone-based speech assessments, clinician-rated assessments of depression, self-report measures of depression, anxiety, and insomnia, and optional passive monitoring of sleep and activity patterns through a mobile application. The study will use machine learning and statistical methods to analyze speech-derived and behavioral data and to develop and evaluate digital biomarkers for assessing depression severity, tracking changes in symptoms over time, and predicting treatment response.
