In contrast, the bulimia studies screened a larger group of contacts and met monthly randomization goals in the time allotted for recruitment. Participants eligible for a study but with a barrier to participation occurred at a much higher rate in the anorexia study than in the bulimia studies.<\/jats:p><\/jats:sec>Discussion<\/jats:title>These results reveal a difficulty in planning recruitment from a small population such as partially recovered anorexics. A small population's total pool size diminishes faster than it is replenished, suggesting that future studies of anorexia nervosa may recruit more successfully from many sites in a short period rather than at a few sites over a long period. \u00a9 2003 by Wiley Periodicals, Inc.
