Cox proportional hazard (PH) regression analyses predicting time to onset of AUD were conducted for the total sample considering the interaction between race and CPA endorsement pattern. We observed a significant interaction for race and CPA behavioral endorsement (X2 = 2.77, p = .096), which motivated stratification of further analyses by race, – considering models for EA and AA women separately. Cox PH regression analyses based on a) behavioral questions; b) trauma checklist items and finally c) CPA reporting pattern as predictors for DSM-5 AUD diagnosis were considered. In the complete model, predictors included dummy variables representing behavioral endorsement only, checklist endorsement only, and behavioral and checklist endorsement groups as well as maternal and paternal alcohol problems, MDD, CD, regular smoking, cannabis dependence, and history of CSA as covariates using the method previously described. All CPA variables, as well as MDD, regular smoking, cannabis dependence, and history of CSA were considered as time-varying predictors.
