may involve problematic drinking in addition to PTS symptoms. The young ages at which subjects first reported trauma underscores further the clinical importance of early detection and intervention in families where there is a history of AUD. Increasingly COGA researchers have noted that trauma exposure is salient to our understanding of family alcoholism (Bender et al., 2020; Meyers et al., 2019). Among the offspring of parents with AUD, trauma exposure is common and symptomology is complex, involving features of multiple psychiatric disorders. Using person-centered methods such as LCA is a commonsense approach to understanding the heterogeneity of symptoms, trauma types, and individual-level characteristics associated with trauma-exposed individuals and comorbid AUD-PTSD. We situate our findings within the understanding that research into effective prevention and treatment strategies for AUD ought to take the likelihood of trauma exposure and the co-occurrence of PTS symptoms into account.
