Notes

^*1. p<0.05,

^**p<0.01, and

^***p<0.005 (Bonferoni Adjustment for 10 tests);

2. O.R. = Odds ratio without controls;

3. A.O.R. = Adjusted odds ratios by including earlier delinquency, internalizing behavior, education expectation and aspiration, and demographic factors (i.e., gender, age, and parental educational level) as controls.
