Results are presented as unadjusted comparisons of group means across the conduct-problem subgroups. Alternative specifications were also fit to the data and illustrated that results from between-group comparisons were robust to months spent outside of New Zealand, childhood socioeconomic status, and the differential sex composition of conduct trajectory groups by statistically controlling for months spent in the country, socioeconomic status, and sex, respectively (see online version for tables S1, S2, and S3). Furthermore, patterns of service use across conduct trajectory groups were similar for males versus females, as evidenced both by disaggregating results by sex and by testing for sex interactions in all models (see online version for tables S4 and S5).
