Forecasting recidivism in delinquency by intelligence and related constructs

Area of Science:

• Neuroscience
• Criminology
• Psychology

Background:

• Understanding factors influencing criminal recidivism is crucial for effective rehabilitation and public safety.
• Intelligence and neuropsychological functioning are potential correlates of criminal behavior and reoffending patterns.

Purpose of the Study:

• To investigate the relationship between intelligence (measured by Wechsler Adult Intelligence Scale - WAIS), neuropsychological scales, and delinquency in a cohort of criminal offenders.
• To identify predictors of recidivism among young adult offenders.

Main Methods:

• A longitudinal survey of 122 healthy male criminal offenders aged 18-37 years.
• Assessment of intelligence using the Wechsler Adult Intelligence Scale (WAIS) and other neuropsychological tests.
• Tracking of recidivism rates over 1.5 and 3-year periods.

Main Results:

• Offenders had normal average intelligence scores (IQ=102) but poor educational and work histories.
• Significantly worse performance on the WAIS Verbal Scale and Block Design sub-test was observed in offenders who relapsed.
• Poor performance in WAIS Information and Block Design, low education, and external locus of control predicted higher recidivism risk.

Conclusions:

• Specific cognitive deficits, particularly in verbal and visual-spatial domains measured by the WAIS, are associated with a higher risk of recidivism in criminal offenders.
• Neuropsychological assessments, alongside educational background and locus of control, can aid in identifying individuals at high risk for reoffending.
