Background: Although previous studies from Western nations had reported elevated rates of antisocial personality disorder (ASPD) among incarcerated offenders, there are limited studies from the developing nations like ours. The study was aimed at determining the prevalence of ASPD in a prison population and its association with social and substance use variables. Methods: Using a cross-sectional survey, 277 randomly selected incarcerated offenders were assessed using a sociodemographic questionnaire and Structured Clinical Interview using the Mini-International Neuropsychiatric Interview plus to assess ASPD and substance use disorders. Diagnoses were made based on the Diagnostic and Statistical Manual of Mental Disorders-4th edition and the 10th revision of the International Statistical Classification of Diseases and Related Health Problems. Results: The prevalence of ASPD in this population of offenders was 13.5%. The most common offense was armed robbery. Offenders with ASPD were more likely to be unemployed prior to imprisonment and have a father who uses or abuses alcohol or cannabis. Significantly, those with ASPD were more likely to meet criteria for alcohol and cannabis use disorders. Conclusion: There is an elevated rate of ASPD among incarcerated offenders, and such offenders need to be evaluated for alcohol and substance use disorders to ensure smooth rehabilitation.
