Depression and anxiety disorders are common at all ages. Approximately one out of three people in the Netherlands will be faced with them at some time during their lives. It is still not clear why some people recover quickly and why others suffer for long periods of time. The Netherlands Study of Depression and Anxiety (NESDA) was therefore designed to investigate the course of depression and anxiety disorders over a period of several years. We have recruited 2981 partcipants with and without symptoms from primary care practices and specialised mental health institutions in the regions of Amsterdamand Leiden, and in the provinces of Groningen, Drenthe and Friesland. Inclusion is complete; we do not need any more participants.
The main aim of NESDA is to determine the factors that influence the development and the long-term prognosis of anxiety and depression. The researchers will try to find answers to important questions like:
- What makes people susceptible to anxiety disorders or
- Why is one person depressed for three months, while the other
is depressed for three years?
- What is the influence of biological and genetic factors?
- What are the implications of a depression or anxiety
disorder for income and work?
We expect the results of this study to contribute to the improvement of care for persons with anxiety or depression. In addition, reliable data is needed to establish appropriate preventative measures.
NESDA is a cooperative project of
- VU University Medical Center
- Leiden University Medical Center/Leiden University
- University Medical Center Groningen / Groningen University
- several mental health care institutions
- Trimbos, NIVEL, WOK
- several client organisations
