| Lifetime SU by 1 year later | 2.47 (1.9–3.3) |
| SU initiated during subsequent year | 1.59 (1.1–2.3) |
| Lifetime conduct problems concurrent | 4.87 (3.5–6.8) |
| Lifetime conduct problems by 1 year later | 2.44 (1.8–3.3) |
| Conduct problems initiated during subsequent year | 1.63 (1.0–2.5) |
| Psychometric Sample | |
| Lifetime SU concurrent | 2.76 (2.0–3.8) |
| Lifetime conduct problems concurrent | 6.07 (4.1–9.0) |
| Well-Child Sample | |
| Lifetime SU concurrent | 2.55 (1.1–5.8) |
| Lifetime conduct problems concurrent | 3.69 (1.6–8.6) |
Note: All results p<.001, tested using χ2. Parenthetical values present 95% confidence intervals (an odds ratio meets p<.05 if the CI fails to cross 1.0).
