Volunteers were typically screened within 24 hours to one week from their initial contact. The days and times of the focus groups were predetermined with the goal of having about six groups of 4–8 individuals, over a period of six to eight weeks. By the time screening was complete and the groups were formed, 27 people had been eliminated. Thirteen were found to be ineligible on the basis of ethnicity, and 5 reported having had a history of psychosis outside of depression. Eight people had schedules that could not be accommodated by research staff.
