Note: Marijuana use was based on any past 30-day use. Intentions were measured from 1 = definitely no to 4 = definitely yes. Expectancies were measured from 1 = strongly disagree to 4 = strongly agree. Consequences were based on whether youth experienced any consequences in the past year. All growth factor estimates are significant at p < .05. Model fit indices: Use (χ2 = 250.84, p < .05, RMSEA = 0.01, CFI = 0.98, WRMR = 1.17); Intentions (χ2 = 421.54, p < .05, RMSEA = 0.02, CFI = 0.98, WRMR = 1.45); Expectancies (χ2 = 274.57, p < .05, RMSEA = 0.01, CFI = 0.97 WRMR = 1.17); Consequences (χ2 = 277.08, p < .05, RMSEA = 0.01, CFI = 0.97, WRMR = 1.24).
