In adolescence and adulthood, mental illness is well known to be associated with an increased risk of criminal justice contact, including contact with police, but whether the association is also important in earlier life is unknown.
In a sample of 79,801 children entering their first year of full-time schooling (average age 5 years) in New South Wales in 2009, emotional and behavioural problems, along with previously established profiles of developmental risk using data from the Australian Early Development Census, were examined in relation to subsequent contact with police using survival analysis of the period following school entry up to age 13 years.
An association between childhood emotional/behavioural problems, developmental risk, and contact with the police was confirmed. Amongst children with at least one police contact, almost one-third had been identified as having emotional/behavioural problems at school entry. Rates of police contact for the full range of reasons (as a person-of interest, victim, witness) were all increased for children with identified emotional/behavioural problems, as well as for those with particular developmental risk profiles (particularly those in with the ‘pervasive’ risk profile). Key differences were identified when the relationship was examined separately for boys and girls, and when rates of police contact were calculated in relation to sociodemographic covariates.
The results of this study have implications for understanding risk of early criminal justice contact, an outcome known to be a strong marker for long-term adversity across educational, occupational, health and justice domains. Interventions intended to reduce risk of early justice contact need to consider children with developmental vulnerabilities, including but not limited to emotional/behavioural problems, and may need to target boys and girls differently.
