Externalizing psychopathology and persistence of offending in childhood first-time arrestees

This study aims to investigate the predictive validity of externalizing psychopathology for persistence in delinquent behavior when controlling for socio-demographic and first arrest characteristics in childhood first-time arrestees. A sample of first-time arrestees aged under 12 (n = 192) was assessed using the Diagnostic Interview Schedule for Children (DISC-IV) parent-version on attention deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD) and conduct disorder (CD). Based on child and parent reports of offending as obtained at arrest and at 2-year follow-up, three groups of offenders were differentiated: (1) persistent high (n = 48), (2) occasional (n = 62), and (3) persistent low offenders (n = 82). Over one-third of the sample (33.9%) was diagnosed with an externalizing disorder, and 13.5% with both ADHD and ODD or CD. Higher levels of externalizing psychopathology distinguished persistent high offenders from occasional (comorbid ADHD and ODD/CD: OR 8.2, CI 2.6–25.5) and persistent low offenders (comorbid ADHD and ODD/CD: OR 18.2, CI 4.6–72.3; ADHD: OR 4.1, CI 1.3–13.0), over and above socio-demographic and first offense characteristics. Living with both biological parents distinguished the persistent low offenders from the occasional offenders (OR 2.5, CI 1.2–5.0). Since the prevalence of externalizing disorders was high and predicted re-offending, mental health screening and intervention initiatives, aiming at these conditions, should be investigated for this high-risk sample.
