Prevalence of psychiatric disorders among sentenced prisoners in a medium security prison in Ghana: Implications for mental health assessment and service

Abstract

AbstractBackgroundExtant literature has shown that there is a higher prevalence of mental disorders among prisoners compared to the general population. These findings have, however, mostly been from high‐income and westernised cultures. In Ghana, little is known about the extent of psychiatric disorders among prisoners, as is consistent with the dearth of scholarly work in low and middle‐income countries.AimsOur aim was to determine the prevalence of common mental disorders among sentenced prisoners in the second largest prison in Ghana.MethodsA cross‐sectional survey research design was used in one prison. The Mini International Neuro‐Psychiatric Interview questionnaire was used to collect data from men and women serving prison sentences who volunteered for the study. Socio‐demographic characteristics and criminal history data were collected using a questionnaire designed by the researchers.ResultsFive hundred prisoners participated. Nearly half (246, 49.8%) had at least one psychiatric disorder. The most prevalent disorders were major depression and a range of anxiety disorders (145, 29%, 132, 26% respectively). A smaller proportion recorded high scores on the antisocial personality disorder scale (13%); just 50 (10%) reported using substances in the 12 months before interview, but this is a minimum estimate of such problems as many were already in prison during that time. None of these prisoners, regardless of disorder, had been screened, diagnosed, or treated in prison.ConclusionsThis study contributes to the gap in scholarly literature in low‐ and middle‐income countries on psychiatric disorders in the prison population. It will be important to explore further the extent to which the internationally recognised screening tools used led to under‐estimation of psychiatric disorders. The findings are of immediate practical importance nationally as they highlight the need to implement reforms anticipated by the new mental health legislation of 2012 and strategies for interagency working to improve health services and their uptake in the criminal justice system.
