Tests of Slope Main Effects for Parallel Process Growth Curve Modeling for Peer Delinquency and Depression on Substance Use

Parameter Estimate S.E. pseudo z
Peer Delinquency (S1) −0.05 0.03 −1.71
Substance Use Categorical (S2a) 0.17 0.07 2.53*
Substance Use Continuous (S2b) 0.03 0.02 1.58
S1 → S2a 2.61 0.71 3.68***
S1 → S2b 0.76 0.36 2.14*
Depression (S1) −0.76 0.25 −3.06**
Substance Use Categorical (S2a) 0.18 0.16 1.11
Substance Use Continuous (S2b) 0.03 0.05 0.54
S1 → S2a 0.26 0.15 1.73
S1 → S2b 0.09 0.04 2.40*

Note. S.E. = standard error. Pseudo z = Estimate/S.E. S1 = linear slope for peer delinquency. S2a = linear slope for categorical part of substance use two-part model. S2ba = linear slope for continuous part of substance use two-part model.
