Secondly, we examined associations of trauma types and parental AUD status with the latent classes of AUD and PTSD symptom clusters, using multinomial logistic regression. This model enabled us to determine the association of mother-only, father-only, or both-parent AUD with the class profiles. For the regressions, we hypothesized that the presence of one or more parents with AUD would be significantly, positively associated with experiencing any trauma, and that this relationship would be particularly strong for family configurations in which the mother was affected by AUD, in keeping with a previous analysis of these data (e.g. Bender et al., 2020).
