ENThis research study aims to identify the key stresses encountered by police officers in Lithuania in 2003. A questionnaire was distributed to officers working in police departments throughout Lithuania. The 2003 results were a compared with a similar study carried out among male and female police officers in Lithuania 1999. The stressors determined to have the greatest negative effects were administrative problems, family problems, and an ineffective criminal justice system. Identified consequences of police stress included depression, alcoholism, physical illness, and suicide. Dealing with stressful situations led to more frequent physical illness in female police officers and higher alcohol consumption in male police officers. This paper confirms the findings of previous studies. It adds to the knowledge of the unique stresses affecting police officers. It briefly explores the consequences of stress in police work. Since the study represents a small sample of the 15,000 police officers in Lithuania, caution is urged in the application of the findings to other police departments. [From the publication]
