Risk assessment tools for recidivism have been validated extensively in youth justice populations. These validation studies typically demonstrate good predictive accuracy, leading many jurisdictions to implement structured approaches across custody and community supervision settings. However, previous research has focused primarily on single supervision contexts, with limited examination of whether predictions maintain their accuracy when applied across different settings. This gap has implications for jurisdictions applying similar risk assessment protocols across different supervision settings. Our study examined whether violent recidivism predictions maintain their accuracy across youth custodial and community supervision contexts. We developed a predictive model using data from custodial youth (n = 790) and evaluated its performance among community-supervised youth (n = 766) in New South Wales, Australia. Two-year violent recidivism was higher in custody (37%) than in community supervision (27%). The model showed good discrimination in both custody (AUC 0.771, 95% CI: 0.735–0.807) and community settings (AUC 0.728, 95% CI: 0.685–0.770). While adjusting the baseline hazard improved absolute risk prediction, optimal performance across the risk spectrum required additional adjustments to the linear predictor. This suggests that the strength and pattern of risk factor relationships may vary across different settings; therefore, statistical adjustments may be necessary when applying predictions across various contexts.
