title: "Normal" control subjects are hard to find: a model for centralized recruitment.
abstract: A central program for recruiting "normal" control subjects is examined by considering the yield of subjects who meet criteria for "healthy" as defined by their personal and family histories of mental disorders. Of the 267 applicants, 30.3% have no lifetime diagnoses, 41.2% are currently healthy with a history of mental illness, and 27.7% are currently mentally ill. Only 16.1% met Research Diagnostic Criteria for "never mentally ill" and reported no family history of mental disorders. Benefits of a central recruitment program for studies of mental disorders include increased information on a large subject pool and decreased volunteer bias.
