Clinical depression is a recurrent illness requiring treatment and often hospitalization. During the 1980's the federal government, through the National Institutes of Health (NIH), sponsored a multi- centered, randomized, controlled, clinical trial to evaluate two drugs to prevent the recurrence of depression in patients who have had at least one previous episode of the illness. 109 volunteers with diagnosed clinical depression were randomly assigned to one of 3 treatment groups taking lithium, imipramine, and a placebo. Patients were followed for 2-4 years to see whether or not they had a recurrence of depression. If they did not have a recurrence of depression within this time frame, then their treatment was considered a "success". If they did have a recurrence, it was considered a Failure. The study was double-blinded. A number of additional background variables were measured for each patient. The following variables were recorded.
