The effect of incarceration on prisoners' perception of their health.

The aim of the study is to assess the quality of life among male prisoners using the French version of the Nottingham Health Profile, then to investigate the influence of incarceration on emotional reaction. Before the obligatory medical examination at reception into prison, self-administration by prisoners of the French version of the Nottingham Health Profile. Two prisons in Toulouse (south-western France) are concerned: 199 men are included. The score of each dimension on the French version of the Nottingham Health Profile questionnaire and the responses to questions on socio-demographic and penal characteristics and results of medical survey have been studied. The response rate and rate of completion for each dimension are excellent (100%). Considerable evidence is found for the reliability of the Nottingham Health Profile (Cronbach a > 0.72 for all dimensions except energy 0.64 and physical mobility 0.64) and for construct validity in terms of distinguishing between groups with expected health differences. Three variables concerning aspects of life in prison are correlated with variation of the emotional reaction dimension. The Nottingham Health Profile can be used in prison populations. It is easy to use, acceptable to inmates, and fulfils stringent criteria of reliability and validity. It allows recognition of the factors correlated with variation of emotional reaction classically connected with suicidal behaviour in prison.
