Chunk #20 — Results — Analyses Predicting Intercept, Slope, and Quadratic Curvature of the Longitudinal Course of Heavy Episodic Drinking — Parental Separation
As shown in Table 3, in the EA sample, parental separation was associated with a higher HED intercept. PGSPAU was associated with a more rapid escalation of HED and a less pronounced quadratic decline, indicating a slower decline in HED in the mid and late 20s. Figure S1, available online, depicts the predicted value for HED across ages 12 to 32 years by sex, conditioned on parental separation. In the interactive effects model, there was no evidence that parental separation modified the effect of PGSPAU on the longitudinal course of HED. In the AA sample, as shown in Table 4, there were no significant main effects or interactive effects for PGSPAU and parental separation on the intercept, linear slope, or quadratic term of HED across time.
