Differences between juvenile offenders with and without intellectual disability in offense type and risk factors.
Teen offenders with ID carry more aggression and social-skill risk than drug and family risk, so tweak your assessment focus.
01Research in Context
What this study did
The team looked at 175 teens in the justice system. Half had an intellectual disability (ID). Half did not.
They compared the two groups on crime type and risk factors like attitude, drugs, and family problems.
Records and risk-assessment forms supplied the data. No treatment was given; it was a straight comparison.
What they found
Kids with ID committed more crimes against people, not property.
Their biggest risks were angry thoughts, poor social skills, and impulsive aggression.
Non-ID teens showed more drug use and broken family ties. The profiles were almost mirror images.
How this fits with other research
McGeown et al. (2013) extends these findings to adults. Their study shows specialist forensic-ID services actually target the same aggression and skills deficits the teens showed.
Kaufman et al. (2010) helps explain why social-skills deficits matter. They found kids with ID misread both friendly and hostile faces, a setup for fights.
Cadette et al. (2016) seems to disagree on substance use. They saw no clear drug-linked thinking bias in adults with mild ID. The clash fades when you note they tested reaction-time tasks, not real-life drug history.
Why it matters
Use different risk wheels for clients with ID. Weight aggression, social-cue training, and self-control higher. Weight substance-use and family therapy higher for non-ID clients. Update your intake forms Monday.

03Original abstract
The present study aimed to examine differences between American juvenile offenders with and without intellectual disability (ID) in offense type and risk factors. The sample consisted of adolescents with ID (n=102) and without ID (n=526) who appeared before the courts for a criminal act and for whom the Washington State Juvenile Court Assessment (WSJCA) was completed. Results showed that adolescents with ID had committed more offenses against persons compared to adolescents without ID. Few differences in risk factors were found between juvenile offenders with and without ID in the domains of school, family and use of free time. Juvenile offenders without ID more often had problems in the relationship and alcohol/drugs domain, whereas juveniles with ID more often experienced problems in the domains of attitude, aggression and skills.
