ABSTRACT
BACKGROUND: Extant 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. AIMS: Our aim was to determine the prevalence of common mental disorders among sentenced prisoners in the second largest prison in Ghana. METHODS: A 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. RESULTS: Five 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. CONCLUSIONS: This 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.
ABSTRACT
BACKGROUND: Research shows that the prevalence of substance use disorders among the prison population is high globally. Although prisons are highly controlled environments, access to drugs and other substances in prison remains a major problem. Yet, previous research is focussed mainly on the Western context, with the studies generally reporting on lifetime prevalence without reference to whether the disorders are manifest even within the controlled environment. AIMS: To estimate the prevalence of substance use disorders evident while in prison in Ghana and associated risk indicators. For these purposes, substance use disorder was defined by any indication of dependency, or escalating use or socially problematic use during the 12 months of imprisonment prior to the interview. METHODS: The study involved 500 adults (443 men and 57 women) in a medium-security prison in Ghana who had served at least 1 year of a prison sentence. Participants' alcohol use disorder was assessed separately from other substance use disorders which included cannabis, cocaine and other stimulants using the Mini International Neuropsychiatric Interview (MINI); it is a structured interview and diagnostic tool for major psychiatric and substance use disorders in DSM-5 and ICD-10. RESULTS: Two percent of the 500 participants had used alcohol to the level of alcohol use disorder, and 6% had other substance use disorders in 12 months prior to interview and while in prison. Cannabis (4%) and stimulants (3%) were the most frequently reported substance use disorders. Logistic regression model estimates indicate that younger age, prior offending and alcohol use dependence were significantly associated with such disorders in prison. CONCLUSION: In spite of efforts to prevent substance use in prison, nearly one in 10 of these prisoners were using alcohol or illicit drugs to a level indicative of substance use disorders. Our findings suggest that prioritising brief assessment may help identify those in most need of clinical help to limit their alcohol and illicit substance use problems.
