Summary
Background People with an intellectual disability are significantly over‐represented in the criminal justice system in many Western jurisdictions; early identification in the system is important if they are to receive appropriate services, protection, diversion and rehabilitation.
Methods The Kaufman Brief Intelligence Test (KBIT) and the Vineland Adaptive Behavior Scales (VABS) were compared with the Hayes Ability Screening Index (HASI), developed from a battery of items. In total, 567 adult and juvenile offenders, in custodial and community settings, were tested.
Results Receiver operating characteristic (ROC) curve analyses showed that the final version of the HASI was as effective as the KBIT or the VABS in predicting results on the other test. Correlation coefficients between the HASI, the KBIT and VABS were significant.
Conclusions The HASI is an effective screening instrument for determining offenders who may have an intellectual disability and need to be referred for full‐scale diagnostic assessment.
