Background: Alcohol use and misuse may be lower in people with intellectual disability (ID) than in the general population but may be related to offending. Method: Alcohol-related crime and history of alcohol use was recorded in 477 participants with ID referred to forensic ID services and related to offending. Results: Level of alcohol-related crime and history of alcohol misuse was lower than in some previous studies at 5.9% and 20.8%, respectively. History of alcohol abuse was associated with alcohol-related offences and theft. Higher rates of alcohol problem history were associated with histories of a number of offences, psychiatric disturbance in adulthood, psychiatric disturbance in childhood, and experiences of childhood adversity. Most effect sizes were weak or moderate. Conclusions: The convergence of childhood adversity, psychiatric problems in childhood and adulthood, and alcohol abuse is consistent with studies that have found these as risk markers for offending.
