Title: Adolescent and Adult Offender Recidivism Rates After Cognitive Behavioural Therapy: A Comparison Using Meta-Analysis
Authors: Marshall, Alex
Award date: 2012
Abstract: Moffitt (1993) suggested that adolescence-limited offending may be normative; cognitive skills and prosocial models facilitate future desistance. However, life-course persistent offending may result from neuropsychological deficits and criminogenic environments. Cognitive-Behavioural Therapy programmes should dramatically reduce adolescent reoffending by providing opportunities for cognitive skill acquisition and prosocial modelling. Adult participants should not desist to the same degree due to lowered ability for skill acquisition. A meta-analysis of 41 studies investigated if there were significant differences between adolescents and adults on recidivism rates after completing CBT. It was found that CBT was more effective for adults (r = 0.11; CI = 0.07 – 0.15) than adolescents (r = 0.06; CI = 0.01 – 0.12); this was significant (z = 3.84, p < 0.05). Perhaps the negative effects from Criminal Justice System attention (e.g. labelling and criminal record) outweigh the positive effects of CBT. However, differences between the groups regarding CBT delivery may have confounded results. Issues included underreporting of integrity measures and changes to settings in which CBT is delivered compared to earlier studies that demonstrated higher success. Moderators that affect CBT’s success for adults included the recidivism measure, CBT’s emphasis and country of delivery. Implications for theory, practice and future research are discussed.
