Binary Logistic Forward (Wald) Regression Examining Childhood Maltreatment, CD, Parental Substance Use, Maltreatment * Parental Substance Use Problems, and Maltreatment * CD as Predictors of Adolescent SUDs

Variable	β	SE	Wald	p	OR	CI (95%)
SES (control variable)	.030	.017	3.02	.082	1.03	0.99–1.07
Maltreatment	1.99	.723	7.56	.006	7.30	1.77–31.14
Conduct Disorder	1.26	.567	4.88	.027	3.52	1.15–10.73
Parental Substance Use Problems	1.19	.645	3.38	.066	3.28	0.93–11.60
Maltreatment * Parental Substance Use Problems	1.13	.595	3.58	.060	3.08	0.96–9.88
Maltreatment * CD	−2.37	1.74	1.85	.173	.093	.003–2.84

Note. β = regression coefficient; SE = standard error; Wald = z-score; p = probability value for Wald; OR = odds ratio expressed as % increase in odds: 100(e^β − 1); CI = 95% confidence interval for the odds ratio. The above models included 3 variables; Maltreatment, CD, Parental Substance Use Problems, using the forward (Wald) stepwise method, and 2 interaction terms; Maltreatment by Parental Substance Use Problems and Maltreatment by CD. Parental Substance Use Problems did not reach statistical significance on any step. The interaction terms were not significant. SES was entered as a control variable in the equation.
