All analyses were conducted with version 14 of StataSE; analyses proceeded as follows. First, Poisson regression models were used to test whether children on the LCP pathway, on average, went on to consume more criminal justice, health care, and social welfare services in adulthood than their peers on the low, childhood-limited, and adolescent-onset pathways. The average number of criminal convictions, hospital bed-nights, prescription fills, emergency department visits, injury claims, and social-welfare benefit-months by trajectory group are reported. Additionally, the proportion of total services used by children on the LCP pathway was computed to describe whether they consumed more than their expected share of services as adults. Next, Poisson regression models were used to investigate whether individuals following the childhood-limited pathway resembled “true recoveries” in terms of their service utilization by testing whether they used significantly more services than their peers on the low-conduct problem trajectory. Finally, logistic regression models were used to test whether LCP and childhood-limited study members had significantly higher odds of accumulating high multiple-domain service usage relative to those on the low conduct-problem trajectory.
