Formal Tests of Mean Inattentive-Hyperactive Behavior, Oppositional Behavior, and Conduct Problems at 4–7 Years as Predictors of Mean Conduct Problems at 8–13 Years Using Log-Linear Regression in Generalized Estimating Equations

Predictor at 4–7 Years	β	z	p <
Separate Models: In Which Each Single Predictor¹ and the Demographic Covariates Were Entered Simultaneously in Three Separate Models
Inattentive-hyperactive behavior	.34	33.82	.0001
Oppositional behavior	.36	35.74	.0001
Conduct problems	.39	36.74	.0001

Single Model: In Which All Three Early Predictors and Demographic Covariates Were Entered Simultaneously in One Model
Inattentive-hyperactive behavior	.11	8.84	.0001
Oppositional behavior	.10	7.75	.0001
Conduct problems	.27	20.36	.0001

Each predictor was converted to a standardized z score to facilitate comparisons.
