The relationship between prior suicidal behavior and mortality among individuals in community corrections

Individuals under community corrections have multiple risk factors for mortality including exposure to a criminal environment, drug use, social stress, and a lack of medical care that predispose them to accidents, homicides, medical morbidities, and suicide. The literature suggests that prior suicidal behavior may be a particularly potent risk factor for mortality among individuals in the criminal justice system.

This study looked to extend the link between history of a suicide attempt and future mortality in a community corrections population.

Using an archival dataset (N = 18,260) collected from 2002 to 2007 of individuals being monitored under community corrections supervision for an average of 217 days (SD = 268), we examined the association between past history of a suicide attempt and mortality.

A Cox Proportional Hazard Model controlling for age, race, gender, and substance dependence indicated that past history of a suicide attempt was independently associated with time to mortality, and demonstrated the second greatest effect after gender.

These data suggest the need for a greater focus on screening and preventive services, particularly for individuals with a history of suicidal behavior, so as to reduce the risk of mortality in community corrections populations.
