The factors associated with criminal recidivism in Finnish male offenders: importance of neurocognitive deficits and substance dependence

Neurocognitive deficits and psychiatric disorders are often brought up as risk factors of recidivism. In this study, we investigated how neurocognitive and academic deficits and psychiatric disorders (including substance dependence) are associated with criminal recidivism and prison career among male offenders. In a health survey of Finnish prisoners, 72 sentenced male prisoners were examined in Turku prison using a neurocognitive test battery and psychiatric assessment including a standardized psychiatric interview (SCID-I, II). The neurocognitive and academic tests were chosen to assess domains of cognitive functioning and reading, spelling and mathematical skills. Our results showed that the combination of neurocognitive deficits and substance dependence was connected to recidivism. Axis I diagnosis (major mental disorders) and substance dependence were connected with neurocognitive and academic deficits. Moreover, first-time offenders had fewer neurocognitive deficits and Axis I disorders, less substance dependence and fewer personality disorders than those with several convictions. Rehabilitation of cognitive functions and academic skills, along with intervention for mental health problems and substance dependence could help to prevent the unfavourable circle of criminal career.
