Risk factors

Individual and environmental risk factors exist, and include clinical factors, housing, and social connection.

Individual factors

  • Pre-existing mental disorders: mood, anxiety, psychotic, and substance use disorders are particularly strong risk factors. Comorbidity (having multiple disorders) further increases risk.
  • History of self-harm or suicide attempts: prisoners with a prior history of self-harm are up to seven times more likely to engage in suicidal behaviour while incarcerated.
  • Suicidal ideation: both current and previous suicidal thoughts are among the strongest predictors of suicide and self-harm in prison.
  • Trauma and childhood abuse: Histories of trauma, including childhood maltreatment, are robust risk markers.
  • Impulsivity and aggression: traits such as poor behavioural control, often seen in violent offenders, are linked to higher suicide risk.
  • Socioeconomic disadvantage: social disadvantage and marginalization are overrepresented in prison populations and contribute to vulnerability.
  • Gender: while both men and women who are incarcerated are at elevated risk compared to their counterparts in the general population, women may have a slightly higher prevalence of suicide attempts, though findings are mixed.

Prison environment factors

  • Solitary confinement and single-cell occupancy: isolation, whether through solitary confinement or being housed alone, is strongly associated with increased suicide risk.
  • Lack of social support: absence of social visits or poor support networks within prison increases risk.
  • Victimization and bullying: experiencing physical or sexual victimization while incarcerated is a significant risk factor.
  • Remand status: prisoners awaiting trial (remand) are at higher risk than those already sentenced.
  • Type of offense: those incarcerated for violent offenses, especially homicide or sexual offenses, have higher suicide risk.
  • Loss of autonomy and purpose: The restrictive, monotonous, and often overcrowded environment of corrections contributes to psychological distress and risk.
  • Disciplinary infractions: involvement in disciplinary incidents within a facility is associated with increased risk of self-harm and suicide attempts.
  • Duration and stage of incarceration: Risk may be heightened during certain periods, such as early incarceration or after disciplinary actions, but this varies by context.

Prisoners who have recently received bad news from home or are demonstrating an inability to adapt to the institutional environment may also be at higher risk.

Prisoners with illnesses are at higher risk of suicide. Prisoners with AIDS have a suicide rate between 16 and 36 times higher than that of the general population.
