Differences between juvenile offenders with and without intellectual disability in offense type and risk factors.

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.
