The relation between mild to borderline intellectual disability (MBID) and violent offense behavior was studied among a group of former juvenile delinquents currently in a diversion program for persistent young adult violent offenders from Amsterdam (N = 146). Offenders were considered MBID if they had received juvenile probation from the local youth care agency specialized in intellectual disability (21%). A file study was used to estimate prevalence rates of criminogenic risk factors. Police data were used to depict recent criminal behavior. Nearly all offenders grew up in large and unstable multi-problem households and had psychosocial problems. More MBID offenders displayed externalizing behavior before the age of 12, were susceptible to peer pressure, and had low social-relational skills. MBID offenders committed more violent property crimes than offenders without MBID. Youth care interventions for MBID offenders should focus on the acquisition of social-relational skills and on the pedagogical skills of parents.
