title: Early detection of psychosis: finding those at clinical high risk.
abstract: OBJECTIVE
  In early detection work, recruiting individuals who meet the prodromal criteria is difficult. The aim of this paper was to describe the development of a research clinic for individuals who appear to be at risk of developing a psychosis and the process for educating the community and obtaining referrals.
  
  
  METHODS
  The outcome of all referrals to the clinic over a 4-year period was examined.
  
  
  RESULTS
  Following an ongoing education campaign that was over inclusive in order to aid recruitment, approximately 27% of all referrals met the criteria for being at clinical high risk of psychosis.
  
  
  CONCLUSIONS
  We are seeing only a small proportion of those in the community who eventually go on to develop a psychotic illness. This raises two important issues, namely how to remedy the situation, and second, the impact of this on current research in terms of sampling bias and generalizability of research findings.
