AIM: This paper reports the rationale, methodology and baseline characteristics of a large long-term follow-up study of first-episode psychosis from a geographically defined catchment area. METHOD: A total of 723 first-episode psychosis patients were recruited from a specialized early psychosis service between 1989 and 2001 and prospectively followed up at a median of 7.4 years after initial presentation. Participants' baseline demographic, clinical and functional characteristics are described. Sampling bias at study recruitment was assessed by comparison with a more complete sample of Early Psychosis Prevention and Intervention Centre (EPPIC) cases rated directly from the medical records.
