Officers employed in jails, short-term correctional facilities with high resident turnover, work in conditions with high exposure to critical incidents and workplace stressors. Jail officers are at high risk for fatal and nonfatal inmate-to-staff and inmate-to-inmate violent incidents, including criminality, gang activity, contraband, manipulation, and rape that contribute to sustained periods of alertness or hypervigilance. Common organizational stressors include inadequate training, low staffing, overtime, poor leadership, and excessive punitive discipline. Although posttraumatic stress disorder (PTSD) has been highlighted among prison officers, little research has been undertaken among this more narrow population of jail correctional officers as a consequence of their particular work setting.
