Two-tailed tests.
Note: All measurement model coefficients statistically significant (p < .05). Model 1 includes a test of the focal relationship between puberty (Pub) and substance use (Sub Use). Model 2 adds dating/mixed sex peers (Date) as a mediator. Model 3 includes the focal relationship and social definitions of substance use (Defs) as a mediating construct. Model 4 includes both social definitions and dating as separate and related mediating constructs.
