Two research studies at the National Institute of Mental Health—one investigating bipolar disorder and the other obsessive-compulsive disorder—will look at genetic markers and genes to help medical researchers understand more about the biological bases for these disorders.

For one of the studies, the Family/Genetic Study of Bipolar Disorder, NIMH researchers are inviting families with two or more siblings with bipolar disorder and their parents to participate in an interview and give a blood sample. The interview gathers information about the participant’s health history, as well as that of some relatives. It will be scheduled at the participant’s convenience, and no travel is needed—most of the work is done by telephone. Participants will be paid $25 dollars for this interview. In addition, a sample of blood will be drawn, allowing researchers to examine DNA, which carries the individual’s genetic information. The blood can be drawn at a clinic or doctor’s office, and the participant is paid an additional $25 for the blood sample.

The other study, the Family/Genetic Study of Obsessive-Compulsive Disorder, is looking to enroll individuals with obsessive-compulsive disorder and their close relatives to complete questionnaires, participate in a phone interview, and give a sample of blood.

The questionnaire will gather a variety of background information about the participant, and the interview will gather a complete health history. Those who join the study will be paid up to $75, as taking part in the questionnaire, interview, and blood sample phases will pay $25 each.

All of the information obtained in the two studies will remain confidential. No information about participants is shared with employers, insurance companies, or any other government agencies.

Individuals who are interested in participating in the Family/Genetic Study of Obsessive-Compulsive Disorderor or would like more information are asked to call John Gause collect at (301) 496-3421.
