Stress, health and the working environment of Swedish prison staff

Abstract
A random stratified sample of just over 2000 was drawn from staff working in 67 different prisons in Sweden. Questionnaires on working conditions and symptoms of ill health were administered and subjects were given health examinations. Morning plasma Cortisol and gamma glutamyltransferase (g GT) levels were measured and factual information on the prisons was collected for use in the analyses. There were differences between prisons in terms of both objective and self-reported working conditions which appeared to affect health status, physiological state and sick leave rate. Cardiovascular and hypertensive conditions were found more often among prison staff than among a large reference group made up of many different occupations. Sick leave rates among prison staff, especially those over 45 years old, were very high compared with this reference group. The situation appeared particularly difficult in prisons with a high proportion of drug abusing inmates. The data allowed the identification of several factors which might counteract the effects of stress at work: a proactive management style, goal consensus among staff, a high degree of decision latitude, satisfaction with work performance and a supportive psychosocial climate.
