National Network of Depression Centers Registry

Principal Investigator: Peter Zandi, Ph.D., M.H.S.

(IRB Protocol # NA_00040237)

What is the National Network of Depression Centers (NNDC) Clinical Care Registry?

Healthcare providers use many different questionnaires and tests to diagnose depression, bipolar disorder, and related conditions, but there is no one set of measurement tools used everywhere to take the mood “vital signs” of a patient, as one might measure a patient’s temperature or blood pressure.

The NNDC is taking the lead in developing such a set of measures which we hope will become the standard for tracking patient progress.

The information we collect from this set of measures will be managed and maintained by the NNDC in one central location called the Clinical Care Registry.

The NNDC has brought together the very best clinicians and researchers - including those here at Johns Hopkins – all working together towards one goal: to improve the lives of persons with mood disorders.

But there’s another crucial ingredient needed to reach this goal: YOU!

We need you, as a person whose life has been touched a mood disorder, to share with us your experiences.

For this research study, patients at NNDC clinics will be asked to fill out questionnaires, which ask about mood symptoms such as sleep and appetite disturbance, about your overall sense of wellbeing, the impact of symptoms on work and social activates, the impact of medication side effects, and other “How are you feeling today?” questions.

The idea is to figure out the best way to follow patients over time, and what sorts of questions most accurately measure improvement - or lack of improvement - during treatment.

We hope that you will join us!
