Long-term Observation of Participants With Mood Disorders

Study Description: The proposal will leverage existing data on former participants with mood disorders collected in the Experimental Therapeutics and Pathophysiology Branch in order to identify predictors of long-term depressive symptoms, suicide attempts and ketamine utilization. The ETPB has collected a wealth of clinical, biologic, neuroimaging and sleep data on individuals with treatment resistant depression and bipolar disorder over the last 20 years. This study would re-contact these individuals for online and telephone assessment of current symptoms. We would then determine the ability of these clinical and biological measures to predict long-term outcomes. For individuals who do not participate in online or telephone data collection, we would like to identify incidence of premature death, including suicide, using linkage to data sources such as the National Death Index. We will also use this protocol for recruitment for in-person neurobiological studies and clinical trials of treatment resistant depression, bipolar disorder and suicide risk, both for ETPB and other branches of the NIMH IRP. Objectives: The primary objective is to identify predictors of long-term treatment-resistant depression. The secondary and tertiary objectives are to identify predictors of long-term risk for suicide attempt and identify predictors of repeat use of ketamine, respectively Endpoints: Primary Endpoint: Score on Beck Depression Inventory Secondary Endpoint: Self-reported suicide attempt after NIH study participation Secondary Endpoint: Self-reported ketamine utilization after NIH study participation Secondary Endpoint: Suicide death as reported by the National Death Index Study Population: The sample size will be up to 1000 participants who previously signed consent into Protocol 01-M-0254: The Evaluation of Patients with Mood and Anxiety Disorders and Healthy Volunteers and will include participants 18 years and older, any gender and health status. Description of Sites/Facilities Enrolling Participants: The study will be conducted online through a secure study website. Data collection can also occur over the phone. Study Duration: 1 year Participant Duration: 20 minutes- 4 hours
