title: Suicidal ideation in prisoners: risk factors and relevance to suicidal behaviour. A prospective case-control study.
abstract: OBJECTIVE
  To investigate risk factors for suicidal ideation (SI) in prisoners, as well as the prediction of suicidal behaviour by SI.
  
  
  METHODS
  Participants were recruited from the all-male,adults', high security prison of Patras, Greece. Sixty-seven prisoners who expressed SI were evaluated using a structured interview, Hamilton's Rating Scale for Anxiety (HAMA) and the Montgomery-Asberg Rating Scale for Depression (MADRS). Sixty-seven control prisoners without SI, matched for age, nationality and penal status were evaluated using the same structured interview and rating scales. All participants were followed-up prospectively for 12 months after their initial assessment and any acts of self-destructive behaviour were recorded.
  
  
  RESULTS
  Independent significant risk factors for SI in prisoners were the family history of suicidal behaviour (OR = 56.34, 95% CI = 4.23-750.1, p < 0.002), history of psychiatric hospitalisation (OR = 7.18, 95% CI = 1.83-28.16, p < 0.005), and higher scores in the MADRS (p < 0.03) and HAMA (p < 0.03) scales. During the follow-up period, suicidal behaviour (suicide attempt or self-mutilation) was observed in 12 (17.9%) inmates with SI, as opposed to none of the controls (p < 0.0001).
  
  
  CONCLUSIONS
  A family history of suicidal behaviour, history of psychiatric hospitalisation and symptoms of anxiety or depression were independent risk factors for SI in prisoners. Inmates with SI had a higher risk for self-destructive acts at follow-up. Inmates with SI are a high-risk group for future self-destructive acts, so special precautions designed to reduce this risk are warranted.
