title: Prevalence and predictors of parasuicide in chronic psychosis. UK700 group.
abstract: OBJECTIVE
  This study estimates the prevalence of and risk factors for parasuicide in a large community-based sample of patients with chronic psychosis.
  
  
  METHODS
  A total of 704 subjects with chronic psychosis were interviewed using a battery of instruments. The 2-year prevalence of parasuicide was estimated and a comparison was made between attempters and nonattempters on a wide range of sociodemographic and clinical variables.
  
  
  RESULTS
  The 2-year prevalence of parasuicide was 18.8%. Attempters were significantly more likely to be younger, of white ethnic origin, to have a diagnosis of affective disorder, to be currently depressed, to have experienced more auditory hallucinations and to have received treatment with antipsychotic drugs for a longer period.
  
  
  CONCLUSIONS
  Parasuicide was found to present a considerable clinical problem in this group. Continual risk assessment is essential to reduce this unacceptably high rate.
