TY - JOUR AB - Purpose Elucidating where antisocial or violent behaviour arises within the life course of individuals with intellectual disability (ID) could improve outcomes within this population, through informing services and interventions which prevent behaviours reaching a forensic threshold. The paper aims to discuss this issue.Design/methodology/approach The Historical Clinical Risk Management-20, Version 3 assessments of a cohort of 84 inpatients within a forensic ID service were analysed for this study, with a particular emphasis on items concerned with the age at which antisocial or violence first emerged.Findings For most participants, violent or antisocial behaviour was first observed in childhood or adolescence. The study also highlighted a smaller subgroup, whose problems with violence or antisocial behaviour were first observed in adulthood.Originality/value The study findings suggest that targeted services in childhood and adolescence may have a role in reducing the offending behaviour and forensic involvement of people with ID. This has implications for the service models provided for children and adolescents with ID with challenging or offending behaviour.
